It's May in 10 months.

The drizzle of light rain has been falling from north to south, from east to west, and the arrival of the plum rain season officially announces the arrival of summer.

At this time, the emperor mobilized the entire palace and began to go south to escape the summer heat.

The place to escape the summer heat is naturally where Laojun Mountain is located, and the summer resort has been repaired.

Early in the morning, Li Fumu returned from school and jumped all the way, looking particularly happy.

After just a few days of studying with her companion, Bai Duoyang said strangely: "It's so comfortable to go to school, why doesn't the Seventh Prince like it?"

"What's the comfort of school?" Li Fumu turned his head and said, "It's only comfortable after school. From Luoyang to Laojun Mountain, you can walk at least two or three days, and then there will be two or three days off."

"Master, go to school and eat to fill your meals. Moreover, you just sit there without having to work, it's comfortable!" Bai Duoyang couldn't help but say.

"Hahaha!" Li Fumu smiled, feeling particularly happy: "Even if it's comfortable, it's really comfortable."

"However, leaving Luoyang, it's good. It's not that hot anymore. There are cool springs in the mountains and forests, so it's comfortable to take a bath!"

When the prince said this, the number of companions behind him became happy one by one.

Luoyang in May is like a steamer, which is quite hot. Everyone is lazy. The dogs on the streets and alleys are sticking out their tongues and lying in the shade.

The lively children were naked and joking from time to time, in groups of three or five. When they met those who sold smoothies on the street, they couldn't help but come over and stare at them.

The vendor didn't rush to speak out, saying bluntly: "Three copper coins are just a bowl, it's so comfortable and sweet!"

Often, the children couldn't help but tempt and ran home and started to make noise. Most of them had bruised noses and swollen faces, and they covered their butts and cried. Only those who were favored happily picked up the copper and bought a bowl.

At this time, it is also the most profitable time to get ice from saltpeter. This ordinary and convenient method is popular among noble families.

It was also at this time that the emperor faced the sun, accompanied by a large number of senior officials, and moved to Laojun Mountain in the south to escape the summer heat.

The entourage staff reached more than a thousand.

The rugged path made everyone feel extremely uncomfortable. After coming to Laojun Mountain, they took a breath.

Seeing this, the emperor couldn't help but say: "The road is so tortuous, the court can expand it, so it's better to marching and transport grain."

"What Your Majesty said is very true!" Sun Zhao couldn't help but agree. He lowered his head, with sweat on his forehead, and said softly: "Nanyang area has been an important food production area since ancient times. The two are smooth, so it's just right for the south to go straight to Luoyang."

Even for the convenience of the emperor and the nobles, Sun Zhao did not dare to make it openly, but instead found a reason and did it naturally.

And don’t you know that Li Jia is using this excuse to start sorting out this important road and relieve stress.

When the emperor heard this, he nodded with a little excitement in his expression. He looked at the road in front of him and couldn't help but say, "I have already made some plans!"

As he said that, he also gestured: "Tang and Dengzhou are located north of the Han River. There are Han Rivers that connect to the Yangtze River, Xiangyang, Jiangling, Changsha Prefecture and other places, and the grain can be transported."

"If you build a wooden rail carriage from Dengzhou, you can directly lead to Luoyang, and you can reach it in two days and nights."

"Wood rail carriage? Two days and nights?"

Sun Zhao felt that the emperor was afraid that it was not heatstroke, so he had never heard of it and had no impression of it.

"I also had a sudden idea."

The emperor smiled awkwardly and said, "The speed of the carriage is limited by the uneven roads. If you put two long wooden tracks in parallel on the ground, let the carriage run from above without any obstacles or interference, and the horses save effort."

"If you change horses and cars, you can even reach outside Luoyang City in one day or night."

Sun Zhao didn't understand any equipment at all and was confused, but he understood that such a cost would definitely be very large.

He said conservatively: "If it is really so powerful, the old minister thinks he should be cautious, and it is even more narrow than the canal!"

"Oh? How do you say it?" the emperor asked in confusion.

"From Dengzhou to Luoyang, there are hundreds of miles, Funiu Mountain, etc., there are many mountain roads. Regardless of the difficulty, just say that this wooden track is not as good as a canal, and it is really easy to be destroyed."

Sun Zhao said with some doubts: "Whether it is man-made or rocks, a little bit can destroy its track. Once it is repaired, it will not be worth the cost!"

After he said this, Li Jia was a little shaken. It was indeed a lot of money.

However, listening to both sides will make it clear, and listening to it partially will make it dark.

Sun Zhao knew that he was very stingy. This was a problem that he developed when he was rich and could not be cured.

Immediately afterwards, just in the afternoon, the emperor summoned the Henan prefect Huang Dezhang.

Huang Dezhang was quite special among the magistrates. He was a rare instrument talent. He started from the Ordnance Department.

Compared to governing the people, he prefers to study equipment.

However, geniuses are all good at it.

With the experience of managing the Ordnance Department, he managed Henan Prefecture with no means to do so.

Especially in managing the Yellow River, with the help of his exquisite equipment, the Yellow River has been very stable in the past two years, with a large amount of silt being dug out, and the Yellow River has suffered from floods, which has greatly improved its control.

With this alone, his political achievements are enough to be proud.

Hearing the emperor summoned, Huang Dezhang immediately entered the Summer Resort.

This villa was built by him personally, refreshing, cool and pleasing to the eye.

"Your Majesty—" Huang Dezhang bowed.

Huang Dezhang, who had more than thirty people, had a steady face and looked trustworthy.

The emperor was very touched, and he cultivated it himself.

"Dezhang, do you think the wooden track is feasible?"

The emperor told his thoughts again and said with expectation.

"Your Majesty, I have been thinking about it for a while, and I think it is feasible!"

Huang Dezhang nodded affirmatively and said, "But, it's better to make this thing yourself than to explain it a hundred times. Let's make a short paragraph first and see how it works!"

"What he said makes sense!" The emperor couldn't hold it in his heart. This thing was just seen in the movie where bullets flew for a while, and the rest were just discussions on the Internet, and he really needed to experiment.

"Your Majesty, not only wooden rails, but also wheels and carriages must be remade. The most important thing is that the distance between wheels must be equal to the distance between wooden rails. If there is a slight difference, the car will be destroyed and the people will die."

This has come to an idea.

There was no precise measurement since modern times in ancient times, and the ancients never realized that, for example, a few, slightly, in daily use, this was fatal in equipment.

However, the Ordnance Department is different. It has long been managed on a large scale, and the units of length have been unified.
