At the same time that Li Zhongwen was marching to Yanting County, Xincheng County with his 30,000 main force and many auxiliary units, a Sui army of about 500 people appeared in Xishui County. These were elite men belonging to the Sixth Army.

They were ordered by their coach Xue Wanjun to secretly go north to monitor Li Zhongwen's every move and provide Xue Wanjun with the most accurate intelligence so that he could plan his next military action.

Yu Zhan was the leader of this elite team. They used climbing tools to cut corners and straighten themselves, and shuttled directly between the mountains. It only took three days to reach Xishui County. Because the marching path was secretive, it was

Neither the woodcutter nor the mountain people knew they existed.

They were hiding in an inaccessible valley, only more than twenty miles away from the Tang Army's Xishui Camp.

The valley is very quiet at this time. Except for necessary patrols, most soldiers are seizing the time to rest. Only by cultivating enough energy can they complete the following tasks with strong physical strength and full spirit.

Two sentries on a leafy tree at the entrance of the valley suddenly noticed three figures running towards them. They immediately raised their crossbows and aimed at the figures that were getting closer and closer. When the uninvited guests approached, the two sentries recognized them.

Two of them were the spies they sent last night, but the other one was wearing a coarse cloth jacket and looked very strong, like a mountain villager.

When the sentry realized that he was one of his own, he put down his crossbow and whistled. The spies who stopped after hearing the sound waved to them, and then pointed to the valley, meaning that they wanted to go into the valley to report. A sentry then shot a loud arrow towards the valley.

Not long after, several soldiers rushed out and led the spies and mountain people into the valley.

There was only a small marching tent in a hidden corner of the valley. They were traveling lightly and should not carry too much supplies. They only used this small tent for command and decision-making. Yu Zhan was drawing a route on the map inside the small tent. His

There are two tasks, one is to closely monitor Li Zhongwen, and the other is to choose the opportunity to harass the Tang army's food route, so that Li Zhongwen's army cannot obtain sufficient supplies. Although the soldiers he leads are not many, their combat effectiveness is extremely high. These five hundred

It can be used as at least three thousand people, so he felt that it would be no problem to harass the Tang army's food supply.

At this time, a soldier reported outside the tent, "General, Shang Deng is back."

Shang Deng was an experienced scout brigade commander who was sent by Yu Zhan to inquire about the situation in the enemy camp. Hearing that he had returned, Yu Zhan quickly said: "Let him come in."

After a while, Shang Deng followed the ordering soldiers into the tent and saluted, "I'm sorry to see you, General."

Yu Zhan was not polite to him, and immediately asked: "How is the situation in the Tang Army's camp? Have you heard any news?"

Shang Deng quickly replied: "Reporting to General, Li Zhongwen has just led the main army to advance to the southwest at noon today. There are about 60,000 shi of food in the camp, and the deputy general Pi Lou Wuche and 5,000 soldiers are closely guarding it."

"Where did the food of the Tang army come from?" Yu Zhan was a little surprised. It would be incredible to him if the Tang army could transport more than 60,000 stones of food from Shu County to Xishui County in a short period of time. If there were powerful forces within the territory,

The water transportation network is pretty much the same; does Brazil County have transportation capabilities that I don’t know about?

"Reporting to the general, I found a woodcutter who has lived near the Xishui camp for a long time. He is familiar with the situation of the Tang army."

"Where are the people?"

"Just outside the tent."

"Bring him to see me quickly."

"Here." Shang Deng went out and brought a young mountain man to him. The man saluted and said, "The grass-roots people have come to the mountain to pay their respects to the general."

"Guan Zhuangshi is exempt from courtesy." Yu Zhan asked him to stand up and asked in a friendly voice: "Where is Guan Zhuangshi from?"

"The grass people are from Feishan Village, Xishui County, and they make a living by collecting firewood."

Yu Zhan asked again: "Guan Zhuangshi, do you know where the Tang army's food was transported?"

Guan Shan said uncertainly: "It was probably transported from Langnei County. I heard that General Zhang Shigui had placed the grain in Langnei County before. After he left Brazil, he did not have time to transport the grain."

Only then did Yu Zhan suddenly realize that Zhang Shigui was originally the Governor of the Brazilian Governor's Office. Qinghua and Tongchuan under his jurisdiction were both on the front line. It would be very unsafe if the logistics center was located in these two counties. Once the Sui army learned about it and launched a surprise attack,

If you fall into the dilemma of having no food to eat, you can simply put it in Langnei County. As long as it is transported from here to Qinghua County to govern Huacheng County, you can go north to Changchi in Qinghuabian County through Danqushui and go south to Tongchuan. Langnei County is also

With the Langshui River and the Western Hanshui River, grain can be sent to Pu'an, Yicheng and Shunzheng in the north through these two waters, and supplies can be obtained from Danququ and Fuling in the south. It can be said that he placed the important logistics in

Langnei is a shrewd choice to achieve multiple goals with one stone. This arrangement alone shows that Zhang Shigui is not a simple person.

Thinking of this, he asked again: "Besides the official road, is there any other shortcut from here to Xishui Camp?"

Guan Shan said: "There are still a few difficult mountain roads that require climbing rocks. Animals cannot walk at all. If there are too many things, even people can't carry them."

After Yu Zhan heard this, he was overjoyed. As long as there was a path to go, he could sneak to the Tang Army's Xishui Camp.

Guan Shan glanced at Shang Deng and whispered: "The general asked me yesterday if there was a way to climb to the top of the camp. I said no at the time, but I just looked at the picture the general drew and suddenly thought that there was a mountain road that could be climbed.

To the top of the military camp."

Yu Zhan was stunned, and then an extremely bold idea flashed across his mind.

...

The logistical center of the Tang Army in Brazil was indeed in Langnei County. However, as all surrounding areas fell into enemy hands, Langnei, as the county seat, had become unsafe. If this area was also lost, the Tang Army would not only lose a grain of food, but

On the contrary, he also funded the Sui army. For safety reasons, Li Zhongwen simply transported the grain from Langnei to Xishui County and set up a logistics camp to the west of Xishui.

The camp is backed by a steep mountain. The mountain is as sharp as a knife and the walls stand thousands of feet tall. There is also a stone wall with a radius of tens of feet hanging above the camp like a huge blue tile. Therefore, this mountain is called Wawu Mountain. But the top of the stone wall

There are thick bushes and vines, and the woods are dense.

At the third watch, Guan Shan brought Yu Zhan and his team to the top of the stone wall, pointed to the cliff in front, and whispered to Yu Zhan: "General, below is the Tang Army's camp."

After speaking, he pointed to the woods ahead and continued the introduction: "Going south from the trees in front of us, you can bypass Xishui County and directly enter Jincheng County."

"Thank you, Master Guan." Yu Zhan said, and walked to the edge of the cliff by the moonlight, grabbed an old mountain vine, gave it a try, and then slowly leaned forward and looked down, his whole body stretched across the cliff.

, everyone including Guan Shan broke into a cold sweat for Yu Zhan, this was really too dangerous.

But Yu Zhan, an expert in art, was bold and looked down without fear. He had extraordinary eyesight and saw a dark camp below. Occasionally, he also saw some torches. Together with the moonlight, Yu Zhan could clearly see the surrounding surroundings.

A circle of camp fence was built.

They had observed it during the day, and found that there were hundreds of large tents in the innermost part, as well as houses made of giant trees. These should be the food tents and warehouses of the Tang army. The large tents in the outer circle were occupied by soldiers guarding the food.

There are sentries patrolling back and forth outside. It is no exaggeration to say that the place is heavily guarded.

However, the Tang army seemed to only focus on what was within eye level, and did not mean that danger could come from above. Perhaps they thought there was no way to go up the mountain, or perhaps they believed that the Sui army had not captured the counties surrounding Xishui.

They were unable to go deep here, but tonight, one of the most elite Sui troops appeared above them.

Yu Zhan's original goal was not the Tang Army's food camp, but the food road that came and went. However, since the opportunity was in front of him, he would not give up casually.

Yu Zhan watched for a while, then returned to the woods and asked the soldiers to take out ten rope net bags. Then he asked the soldiers to take out balls of dried algae from the backpacks. The ones they brought were soaked in lamp oil for three days.

, and then took it out to dry in the sun. It has become light, soft and dry. It is not only easy to catch fire, but also resistant to burning. Each soldier brought a hundred regiments and compacted them in his backpack.

When a thousand balls of dried algae are placed into ten rope net bags, they become ten large round balls.

Yu Zhan said: "Although setting off rockets has the same effect, it also exposes our whereabouts. If it were replaced by these ten fireballs, Tang Jun would have no idea what was going on. As long as we throw the fireballs down, it will be the cliff."

The Tang Army's camp below, even if the mountain wind blows it away, will still fall within the camp. Whether it succeeds or not, we must retreat immediately."

When everything was done, everyone pushed the ten big balls to the edge of the cliff. A soldier lit the big balls with a torch. The flames spread quickly, and then Yu Zhan threw them off the cliff one by one. Everyone didn't even see the effect, and then

Evacuate deeper into the woods.

…

"Look, everyone, what is that?" At this time, a group of Tang soldiers were patrolling under the cliff. A soldier suddenly discovered ten fireballs falling from the sky and shouted in shock.

In fact, there is no need to remind others. After all, these ten big fireballs are so eye-catching. They all saw ten big fireballs falling one after another. When they reached the sky above the big tent, each big fireball suddenly exploded into countless balls and burned.

Small fireballs fell on the big tent.

This is the net bag of the big fire ball that was burned by the raging flames in mid-air. When the mountain wind blew, the oil-soaked and dry algae inside scattered and fell. These soldiers didn't know what was going on. They were scared to death and broke out in cold sweat. They thought it was a will-o'-the-wisp.

Heaven descends.

As countless small fireballs fell, dozens of large tents in the camp were set alight one after another.

The wind assisted the fire, and the fire took advantage of the wind's power. The fire spread quickly. In an instant, the flames soared into the sky. The fire devoured the food and materials in the tent and spread to all sides.

"It's so noisy outside, what happened?" Pilou Wuche, the commander-in-chief of the Tang Army who was sleeping, asked drowsily when he was pushed awake.

The soldier shouted anxiously: "General, something bad has happened. Our barracks is on fire, and the fire has spread to the entire grain camp."

"What?" Pilou Wuche was so shocked that he didn't even bother to put on his shoes, so he ran out of the tent barefoot to look. He saw that the fire in the inner camp was raging, and the raging fire engulfed the entire grain camp. Many soldiers were horrified.

He yelled and ran back and forth to put out the fire, but soon, even the military camp was ignited by the fire that swept over. The stunned Pilouwuche was at a loss for a while, and even forgot to give the order to put out the fire.

At this moment, I heard a panic shout from the soldiers, but a big burning tent was blown up by the strong wind and rushed towards Pilouwuche. The soldiers hurriedly pulled Pilouwuche.

Run, the flying tent happened to cover the main entrance of the Chinese army's tent. Not surprisingly, the Chinese army's tent was also completely engulfed in fire.

After running for a hundred steps, Pilou Wuche finally recovered from the shock. When he saw that the fire was about to engulf the entire military camp, he shouted anxiously: "The fire is too big. There is no need for everyone to work in vain. Everyone leaves the military camp."

, retreat to a safe area."

At this moment, the soldiers of the Tang Army also realized that there was no way to save the day, and they withdrew one after another outside the camp. Pilou Wuche and his soldiers escaped from the camp step by step, but there were still more than a thousand people close to the grain camp, sleeping soundly.

Zhengxiang's soldiers were unable to escape and were burned to death in the military camp.

On a safe high ground outside the camp, thousands of soldiers stared blankly at the raging fire that engulfed the grain camp and the military camp. They were both frightened and surprised at the prospect of surviving the disaster.

But all their rations, military supplies, and equipment were all burned down. What would happen to the army that had already set off? What should they do?

"For humble posts, please see the general." A group of patrolling soldiers were quickly brought to Pilowutcher. They were the first to discover the fire and ring the bell to warn.

"What exactly did you see? Tell me in detail, exactly!" Pilou Wuche's sharp eyes patrolled the sentries. They were very careful and did not allow anyone to bring fire into the grain camp.

, soldiers who patrol the grain camp must be inspected by his direct lineage before entering. In the military camp, even sleeping is not allowed to light a lamp. Even the meals are prepared by the Huotou Army ten miles away and then delivered to the camp.

, why did it catch on fire for no reason? Moreover, it was the internal grain camp that caught fire first, which made Pilowutcher really puzzled.

The sentry team was whispering: "Reporting to the general, I only saw ten groups of fire falling from the sky, and then spread out, falling on the tents of the grain camp, and then the fire broke out."

Pilowucher didn't quite believe it, and asked some witnesses who were sent in one after another. Everyone's stories were similar, so he couldn't believe it. So he looked up at the red mountain. In the middle was a cliff that was impossible to climb, and the top fell down.
