"Boom!" Three days later in the middle of the night, silver snakes cut through the night sky, and their long snake tails brought bursts of thunder!

Strips of pale lightning pierced the dark night sky, and the sound of huge thunder seemed to be ringing in my ears, which was really frightening. The pouring rain continued to fall along with the lightning and thunder.

Changsun Wugou woke up from her sleep. She heard a rustling sound around her and felt that there was someone in the room. She touched it casually, but when she pushed it away, she found that her husband was no longer around.

"Husband?" he called out vaguely.

"Yes!" Yang Tong agreed.

Yang Tong looked through the light of lightning. Changsun Wujia was wrapping herself tightly in a quilt and sitting up. She was tall and graceful. Even though only her face was exposed when curled up like this, she had a strange charm. , at this time, his expression seemed a little confused, but he kept his eyes open hard and asked: "Is it dawn yet?"

Yang Tong smiled and said: "It's still early, it's only about the fourth update."

"Husband, what are you doing up so early?" Changsun Wugou touched the fire sickle beside the bed and lit the candle. He saw that Yang Tong had already dressed and was bending over to put on his boots. His hair was long and draped. If he hadn't heard his words The sound, in this night, really made me think that a ghost had broken in. She chuckled, stretched out her jade lotus-like arm, and waved to him: "Husband, come here!"

"What else are you doing?" Yang Tong chuckled.

"Nonsense, I want to tie up your hair." Changsun Wugou sat up from the quilt. She only wore a bellyband and silk pants, revealing a large area of ​​skin as delicate as suet, "Sit down!"

Yang Tong followed her instructions and sat down next to her. The eldest grandson Wugou knelt on the bed, carefully pulled up his hair, and joked: "My husband got up so late, are you going to be a flower picker?"

Yang Tong touched her thigh with his backhand and said with a smile: "There is a saying that it is better to search far away than to crawl close. With a beautiful girl like you, you still want to be a flower picker? How stupid you must be."

"Stop touching." Changsun Wugu's face turned red again, and she rested her chin on his shoulder: "Would you like to sleep a little longer?"

Yang Tong was rather ticklish, so when he was teased by her thin breathing, his neck naturally shrank. He tried hard to restrain the love in his heart, smiled and shook his head, "I don't."

"Bad guy!" Changsun Wugou lightly punched him on the back and said coquettishly, "I'll just go and be your flower picker."

Yang Tong smiled and said nothing.

Changsun Wugou was just joking with him. He quickly tied his hair into a bun, pushed him, and said with a sweet smile: "Go! My flower picker."

After saying that, he got into the quilt and closed his eyes, "Well! It's still comfortable inside the quilt. Only a fool would run out in the middle of the night."

Yang Tong kissed her pretty face and hurried out. Changsun Wugou slowly opened his eyes, his eyes becoming very gentle.

She knew what her husband was going out to do. The heavy rain had been falling for three days and three nights, occasionally stopping for a moment and then continuing. Not to mention that her husband, the emperor, was worried, but she was also afraid of a shocking flood somewhere.

"Hey! It's not easy to be a good emperor." Changsun Wugao sighed lowly. After a while, he saw that he was tired of sleep, so he simply stopped sleeping. He simply tied up his long hair, put on a dress, and went to the child's room. Go.

…

But he said that Yang Tong left the Fengyi Hall and asked the palace maid to hold a lantern and walk towards the Qianhua Hall to the west of the Qianyang Hall and south of the Xuanzheng Hall.

When he was a left-behind manor in Luoyang, Qianhua Hall was used as a left-behind residence. After regaining the Central Plains, he himself was rarely in Luoyang, so he continued to use it as a left-behind residence, with courtiers on duty every day. Now he encountered this There must be people waiting for the latest news so that they can deal with it in time.

Along the way, it rained continuously.

Lightning tore apart the black clouds, racing and roaring over this long-drought land. The dark clouds gathered and dispersed, dispersed and gathered again, and the darkness was so dense that it was frightening.

The strong wind swept up the newly broken branches on the ground in the courtyard, and the soft flowers and plants trembled and crawled to the ground. Suddenly, in the dark sky above our heads, thunder flashed past, there was a loud roar, and heavy rain poured down with thunder!

This wave of rain was more fierce and violent, hitting the rubble of Langwu with a thunderous sound like hailstones.

Facing this endless rainstorm, Yang Tong felt extremely heavy. The climate this year was extremely abnormal. There had been a long drought and no rain in the past few months. It was only the beginning of summer, and the rolling heat wave had already swept the world. And now, there is another A heavy rainstorm with no end in sight.

What he was worried about was that the ground had been dry for a long time and the cracked soil had become very loose. A sudden flood would cause landslides and landslides. Every time he thought of the disaster in the seventh year of Daye that flooded more than 30 counties in the middle and lower reaches of the Yellow River, There was a heavy rainstorm, and Yang Tong, who had not known what to be afraid of for many years, actually had the same fear as when he first arrived.

Although it has been said throughout the ages that man can conquer nature and encourage people to conquer nature, in fact, mankind has always been made very miserable by God. There will either be a severe drought, a flash flood, or a plague...

When he arrived at the Qianhua Hall, he saw bright lights inside, including the chief officials of the three provinces and ten ministries, as well as the ministers of the nine temples.

Wei Yunqi, the minister in charge of the Ministry of Civil Affairs, Industry and Commerce, was standing next to the sand table at this time, and loudly introduced the situation of the Yellow River to everyone: "In the twelfth year of Yongping in the Han Dynasty, Emperor Ming summoned Wang Jing and asked about the strategy of water control. Wang Jing made a comprehensive analysis Emperor Ming greatly appreciated the incisive response to the situation of the Yellow River. Based on the natural terrain and water regime of the area where the Yellow River flows, he divided the Yellow River into four sections: upper, middle, upper middle, and lower reaches; the upper reaches from the source to Yulin County, this section

High mountains and steep slopes, large water potential differences, more water and less sand, relatively clear river water, and uniform flow are the characteristics of this river section. After the Yellow River leaves Qingtong Gorge in Feng'an County, Lingwu County, it enters the flat and open ancient Hetao Plain, where water canals crisscross. It became one of the earliest agricultural development zones in the upper reaches of the Yellow River."

"The middle reaches from Yulin to Tongguan, this section goes from north to south, shuttling between mountains such as the Qinjin Grand Canyon. Even if a heavy rainstorm occurs, it will not affect both sides of the strait, so it is not very descriptive."

"The middle and upper section is from Tongguan to Taohuayu in Xingyang. This section of the river is fed by tributaries with large flows such as Weishui, Fenshui, Luoshui, Qinshui, Danshui, and Sishui. It is characterized by heavy rains, water and sand in summer and autumn. The flood flow is large, the sand content is high, the river siltation and erosion river sections alternate, and the canyons and wide valleys alternate. It is also the most complex and uncontrollable sandy and watery river section of the entire Yellow River. Zhongtiao Mountain in the north of the river bed, Wang The remnants of the mountains such as Wushan Mountain and Taihang Mountain are higher than the Yellow River. They are natural river embankments and are not affected by floods. On the south bank, after passing the remnants of the Xiaoshan Mountains, there is a gap. To the south of this gap is the Heluo Plain. Shaanxi County. Whenever a flood breaks out, after the flood peak is blocked by the mountains on the north bank, a buffer backflow will be formed, and then it will attack Shaanxian County.

, once the river embankments in Shaanxi County burst, the floods will sweep across the Heluo Plain, directly affecting the safety of the imperial capital Luoyang. Luoyang has one of the most significant features, that is, the Yellow River, Luoshui, Yishui, and Xishui. The "Five Rivers Surrounding Luocheng" formed by the Jianshui River has a large amount of water. Every summer and autumn, the river water will surge, which will not play the role of dividing the Yellow River floods. If the embankment breaks in Shaanxi County, the river water will not only wash away the fields and destroy houses, but also The water levels of Gu River and Luoshui River are rising. If not controlled, it will cause flooding from all five rivers, putting Luoyang in a very dangerous situation. Therefore, Luo River flood control focuses on Shaanxi County."

"The lower reaches of the Yellow River is from Taohua Valley in Xingyang to the mouth of the sea, with a total length of more than 1,500 miles. This section

The slope of the river is small and the water is gentle. In addition, the river is wide, shallow and scattered, with serious sedimentation. The river bed gradually rises, and the embankments on both sides are intermittent and dilapidated. If one of the embankments is terminated, the consequences will be disastrous."

"Can the river embankment in Shaanxian County be defended?" Yang Tong, who was listening silently, saw that he had almost finished speaking, so he asked.

Only then did all the ministers realize that the emperor had arrived, and they all turned around and saluted, "See you, Your Majesty."

"No courtesy!" Yang Tong waved his hand, signaling Wei Yunqi to answer his question.

"Your Majesty, after the Sui Dynasty re-established its capital in Luoyang, we vigorously repaired the infrastructure of Henan County. The river embankments in Shaanxi County were the top priority. After redesign by the Ministry of Industry, the most complete flood control and sand drainage projects were formed. This embankment is divided into four parts from north to south. The low long embankment close to the river bed is called the levee. The levee confines water, shrinks the river bed, and enhances the river's ability to wash away sand. However, building the levee will narrow the river channel. In the event of a major flood, overflow often occurs, so a moon embankment similar to a river channel is built after the strand embankment. When the river water surges, the water will enter the moon embankment and flow eastward; behind the moon embankment is a grid embankment compacted into a tidal flat, which is up to three miles wide. After the grid embankment is the remote embankment that slopes downward. This embankment is two feet higher than the highest water level in history. Its function is to increase the storage and discharge capacity of the river and facilitate the discharge of the peak flow. Although this embankment consists of four embankments, A lot of land is wasted, but during the non-flood season, the dikes, moon dikes and grid dikes between the remote embankments and the river channels are covered with grass and can be used for grazing."

“Where has this long embankment been built?”

"Back to the Holy Spirit, since the remnants of the Yaoshan Mountains were built to the Beimang Mountains, the natural river embankments will be along the south bank of the Yellow River to the Beimang Mountains in Xingyang. Man-made and natural river embankments are connected, and the Heluo Plain will not be affected by the Yellow River. Flooding poison."

Yang Tong walked to the sand table and looked at the Yellow River basin on the sand table. He found that new-style levees had been built on both sides of the Yellow River. "Tell me about this kind of levee."

"Well." Wei Yunqi saluted and continued: "For the management of the Yellow River, the Ministry of Industry now has a relatively mature plan, which is to build a dike on both sides of the north and south to the sea. This new north and south dike contains There are two concepts: "river sand attack" and "wide river embankment consolidation". Among them, "river sand attack" is to stabilize the river channel through dikes on both sides, narrow the river channel, increase the flow rate of water, improve the ability of water flow to flush sand, and use hydraulic power to deepen the river channel. Avoid sedimentation and riverbed uplift. Corresponding to "Shuhe Sand Attack", "Kuanhe Embankment Consolidation" uses the vast beach area between the two banks of embankments to reduce the pressure of floods on embankments and prevent floods from breaking through embankments. At the same time, use The vast beach area detains floods and reduces the pressure on the downstream river section. It can stabilize the wandering river channel to prevent it from changing its course at every turn."

"'Shuhe Sand Attack' plays the role of concentrating water and sand, storing water and navigation during the dry season; 'Kuanhe Dike' plays the role of flood control, diversion and fixing the river course during the high water season. So the two are a kind of simultaneous

Construction, and non-contradictory projects.”

Yang Tong also saw the tributaries that merged into the Yellow River, and the docks and ports along the coast had also built new embankments. He said: "From Xingyang to the mouth of the sea, it is more than 1,500 miles, and the two sides are more than 3,000 miles. If it is a port, dock,

In addition, dozens of miles of new embankments were built on both sides of the tributaries that merged into the Yellow River, and the new embankments were estimated to be more than 4,000 miles long."

"Exactly!"

"This project is quite large."

"Your Majesty! When Wang Jing was ordered to renovate the Bian Canal, which is today's Tongji Canal, he found that the course of the Yellow River was unstable and often changed its course. The water diversion was not well controlled, which caused too much water to enter the Bian Canal, causing the Bian Canal embankment to break.

It was dangerous. So he first built the embankment of the Yellow River from Xingyang Banzhu to the mouth of the sea, and then started to repair the Bian Canal. The entire project involved hundreds of thousands of civilians, took a year, and cost more than 10 billion. Now we have less

In addition to the Tongji Canal, there is an additional north bank embankment. The length of the project is not much different from his. However, the construction volume of the new embankment is about four or five times greater than his. If we use the same number of civilian workers, it should take five times.

Six years, the cost... is naturally more than 50 billion. But..." Wei Yunqi chuckled: "But slaves and war criminals are not paid, they are only for food and drink, so the cost should be similar to him."

Yang Tong smiled knowingly: "From what Wei Pushe said, are you planning to build the Yellow River embankment?"

"Of course!" Wei Yunqi said: "Judging from historical records, the Yellow River after Wang Jing built the embankment has not had any major changes in its course for six to seven hundred years, and there have been only a few overflows. And our kind of line, moon, grid,

The new embankment composed of the four remote embankments has flood control capabilities that are many times stronger than the Wangjing Dike; once completed, it will at least benefit the people on both sides of the Yellow River for a long time to come."

Yang Tong frowned and said, "Wei Pushe, don't forget, we still have projects to divert Luo to Bian and the Yellow River to Huai."

Wei Yunqi cupped his hands and said: "Your Majesty, it is natural to build the project to divert Luo to Bian, and the sooner the better. As for the project of 'diverting the Yellow River to Huai' in the eastern region, I think it can be repaired or not."

Wei Yunqi's words almost represented the thoughts of most courtiers. When Yang Gongren heard this, he saluted and said: "The intention of digging the canal was very good, but now there are Yongji Canal, Tongji Canal, Gangou, and Jiangnan River to connect the north and the south.

The eastern one can indeed be repaired or not; if the goods between 'Liaodong-Yuhang' are really in a hurry to move north and south, they can just walk along the coast. Even if it really needs to be repaired, it should be prioritized and the Yellow River embankment should be built first.

Let’s talk about it after it’s fixed.”

"Your Majesty, I second the proposal!" Huangfu Wuyi saluted and said: "The new canal involves issues such as sand discharge from the estuary, river bank irrigation, lake water storage, river sluices, river bed bridges, etc. All of these, without detailed research and research, will start construction rashly.

It will definitely be an annoying project that people both love and hate. It will be a year later when the drawings are completed. In contrast, the Yellow River Embankment is both urgent and simple. Moreover, after it is completed, the distant embankments on both sides will be very complicated.

It became two official roads running through the east and west."

"What Huangfu said is absolutely true!" Li Jing continued: "Compared with the eastern canal, which makes the government and the public tremble every rainy season, the Yellow River is the top priority."

"I second the proposal"

"I second the proposal"

The rest of the ministers also came forward one by one. Last year, Si Tianjian said "There must be a flood", which made the government and the public nervous from the end of the year to this day. If there were such embankments as "shutting the river to attack sand" and "broad river embankments" coexisting,

Why have you been so nervous for so long? And now it is obvious that Yuan Xi is going to move.

"Since everyone agrees, let's build the Yellow River embankment first." Yang Tong was tyrannical towards his enemies and the family, but in terms of governing the country, he always followed everyone's reasonable suggestions. Everyone in front of him said that the Yellow River was the most important thing, so he suddenly

Be good and follow the flow.

In fact, what Yang Tong was thinking about at this time was waging war abroad and seizing a large number of prisoners from the battlefield to use as labor. Due to the heavy rain, it is not suitable for the several armies in the south to go to war for the time being, but the Fifth Army, headed by Qin Qiong,

The Fourth Army led by Xue Wanshu is far in the north, and the heavy rain will have little impact on them. Moreover, even if there is a disaster in the south, they will not be able to catch up and save the disaster. Rather than letting these 100,000 troops idle, it is better to let them go to the grasslands to train.

Capture slaves.

"The Holy One is wise." All the ministers sang a hymn.

"Your Majesty!" Wei Yunqi said again: "The total length of 'Diversion from Luo to Bian' is only more than seventy miles, half of which can use Guangwu Stream as a natural river bed; if too many people are arranged for the other half, it will be overcrowded and obstructive.

Wei Chen believes that this project only requires 150,000 yuan; the remaining war criminals and the foreign slaves who have repaired the "Kowloon Pilgrimage" project can be divided into two parts, one for Henan and one for Hebei. First, prepare earth, stone, and cement during the rainy season.

Wait for necessary items; in the autumn and winter when the water level drops, the river channel will be dug and the levees and moon embankments will be built. This period happens to be the slack season for farming, and people from both sides of the strait can also be hired to participate in the construction. This can not only ensure the progress of the project, but also increase the number of people.

share of income.”

Wei Yunqi also understood that the current emperor, like the previous emperor, was an impatient person. He would do whatever he wanted to do immediately and quickly. However, in comparison, the emperor in front of him could listen to your opinions and only wanted your opinions and suggestions.

Reasonable, he can give up his claim.

Wei Yunqi's suggestion also satisfied Yang Tong, but he also had his own thoughts and considerations, so he said: "If the levee needs to be repaired, it can be repaired first, but it cannot be repaired without any basis. I think there are two points that we should pay special attention to."

"Please, Your Majesty, please clarify."

"First of all, the concept of 'shushing the river with sand' is very good, but the earthen embankments, moon embankments, and grate embankments cannot withstand the impact and erosion of the flood. If this issue is not considered clearly, there will be endless problems in the future.
To be continued...
