Let’s say that Xie Erjian and Song Dayan each led fifteen people to act separately, digging mountain-filled explosives in two places. When the operation started, each of them carried fifty kilograms of gunpowder, and the total amount was more than 1,500 kilograms. It was not backward black gunpowder, but it was modified and its power was several times stronger. Of course, due to the limited craftsmanship level, its power was naturally far less than that of modern TNT intense explosives, but the amount was large, and it was still more than enough to blow down the Yangyuan stone and cliff.

However, Xie Erjian and others did not make it smoothly. After about half an hour of digging, the brothers in charge of keeping watch sent out a signal of someone approaching, and everyone had to stop and quickly hide.

Soon, a patrol team riding a horse passed by the location where Xie Erjian and others worked, and they were also vigilantly searching along the river, as if they were looking for something. It is estimated that the patrol team that disappeared last night had already aroused the alert of the Yarkand people.

Xie Erjian decisively ordered all actions to be stopped, and he hid in the whole day, waiting until night to move.

There is no doubt that Xie Erjian's decision was very wise, because half an hour later, the second patrol team riding a horse passed by again. Five groups passed in half a day, and the density of the patrol in the afternoon decreased, only three groups.

When it was late at night, Xie Erjian and others immediately seized the time to dig it out. A patrol team came all night, and the light emitted by the torches was discovered by Brother Qianfeng, so Xie Erjian and others were able to hide in time and were not discovered. After the patrol team left, everyone continued to work in the dark. They went through two days and two nights, and before dawn on the third day, everything was ready.

At this time, a rising sun rose from the bottom of the horizon, emitting thousands of rays of light. Xie Erjian and others lay on their backs exhausted in a gully behind Yangyuan Stone, eating their own dry food while resting and resting.

Everyone was so tired that they couldn't eat well and couldn't sleep well. They had to work over night all night. Fortunately, it was early August now, and the weather was not cold at night, otherwise it would be even worse.

Now that the work of placing explosives has been completed, it is only the last step to ignite the mountain and explode it.

Before leaving, Xu Jin and Xie Erjian discussed that during the day, the Ming army attacked downstream to attract the attention of the defenders, so it is best to wait for the second half of the night to ignite the mountain to ensure that when the flood reaches the downstream, it is just dawn, which will not hurt the Ming army, but will also catch the defenders in the valley off guard.

Let’s say that Xie Erjian and others finished eating dry food in a hurry, then lay in the ditches with their clothes to rest as much as possible. They slept until the evening before they woke up.

"Report to the deputy general, there is something going on upstream!"

Shortly after Xie Erjian woke up, a brother in charge of keeping watch climbed down from a high place and tiptoed to him and reported in a low voice.

"What's the situation?" Xie Erjian asked hurriedly.

"A fleet came upstream, and it is estimated that it was transporting the enemy's logistics supplies." The brother rubbed his hands and said.

Xie Erjian's heart moved, and he jumped up. He climbed up to the top of a nearby earth and rock peak like a spirit monkey. He took out his cliff eyes and looked upstream. Sure enough, he saw a fleet of ships. Strictly speaking, it should be a wooden queue, because most of them were wooden rafts, about hundreds of them, and they were downstream in a mighty manner. The wooden rafts were carrying arrows and other items. It was probably the supplies for the Yarkand defenders downstream.

Seeing this, Xie Erjian couldn't help but feel alive. At this time, Song Dayan also climbed up and saw hundreds of rafts down the river. He couldn't help but lit up: "Deputy General Xie, our people should have withdrawn their troops at this time. Why don't we start to launch this fleet when it passes by and give them a big gift to the top of Mount Tai?"

Xie Erjian was just thinking this, but he was worried that the early launch would affect Xu Jin's plan. However, when he heard that Song Dayan was coincident with him, he couldn't help but feel even more moved.

Seeing that the fleet upstream was getting closer and closer, there would be no chance if it was missed. Xie Erjian was not a mother-in-law and immediately decided to start working. After all, the opportunity was rare.

"Big Eyes, let your brothers hide in a safe place. After watching me wave the flag, you should light the fire immediately." Xie Erjian ordered.

"Okay!" Song Dayan immediately climbed down Shi Feng and informed the brothers hiding behind Yang Yuanshi to transfer immediately, and the ignition lead was behind Yang Yuanshi.

After all the brothers were safely transferred, Song Dayan took out the fire and squatted there, while paying attention to the top of the earth and rock peak not far away. In less than half a cup of tea, he saw a small flag stretching out and waved it. Song Dayan was excited and immediately ignited the lead, and then flew like he ran along the earth ditch to the distance.

Speaking of which, the fleet downstream was indeed responsible for transporting supplies to the downstream defenders. A few days ago, Bayi and Li Daren won a battle and wiped out the Ming army's thousand-man team in one fell swoop. Then he sent someone back to Shache City to report the victory to Hasmu, exaggerating the victory with fire and urged the supply of supplies.

Hasmu happened to ascend to the throne to Khan these days, and good news came from the front line, which was a good omen given by heaven. It was a "long-faced joy". Not only did he make people publicize it in the city, but he also issued an order to reward Bayi, Li Daren and others on the spot, and then sent a fleet to transport a large amount of materials to support the front line.

Let’s say that the person responsible for transporting the supplies this time was a commander who used about 300 bamboo steaks. In addition to 100,000 arrows, there was also a large amount of food, etc.

Shache City is located in the middle of the Yarkand River, only three to four hundred miles away from the Mogui Grand Canyon, and it is downstream, so transporting materials and waterways is the most convenient and fastest, and it is also safe.

The Yarkand soldiers who were responsible for escorting supplies probably wouldn't even dream of a catastrophe waiting for them in front of them. Some people were standing on the raft and peeing leisurely on the river.

At this time, the fleet finally arrived under the huge protruding cliff. After a few breaths, there was only a shocking sound. The entire cliff collapsed and directly swallowed up more than a dozen wooden rafts passing by. At the same time, a huge wave was set off. Dozens of wooden rafts nearby were overturned by the huge waves, and people and things sank into the river. The overwhelming rockfall lasted for several minutes before stopping. Many Yarkand soldiers who fell into the river were smashed and injured and knocked out on the spot. The final result of those who were injured and knocked out was drowned.

There were about two hundred wooden rafts that were not affected by luck, but the Yarkand soldiers above were shocked and allowed the wooden rafts to continue to flow down the river. As a result, there was another shocking sound. The tall and long Yangyuan stone fell down and directly crossed the river surface. More than ten wooden rafts were smashed on the spot, and dozens of them were overturned at the same time.

At this time, a large number of falling rocks completely blocked the river channel. The river water rose sharply and spread to the exposed beaches on both sides of the river. The Yarkand soldiers who fell into the water suddenly became worse and countless drowned.

There were dozens of wooden rafts, but they were not affected because they were far behind and far away. The Yarkand soldiers who reacted were panicked and tied the wooden rafts to the shore, then rolled and crawled to the ground, looking at the hell-like river surface in horror.

At this time, the river surface was covered with scattered broken wood, and there were floating corpses everywhere. Some survivors struggled in the water. The strong survivors carried a piece of wood and tried to swim back to the shore. The injured and weakened, they could only turn into a floating corpse in the river.

There were about two or three hundred people in Yarkand Slovakia who had successfully escaped ashore. They stood on the river beach and looked around in horror, all of whom were helpless, obviously still in shock. At this time, the river water came up again, and they had to run upwards, running for five or six hundred meters before the river water stopped rising.

After all, it is not a specially built river dam, and the water leakage is very serious, so the river water can no longer rise after five or six meters high, and the sand and stones are constantly washed away by the water flow. It seems that it will be washed away in a short time and there is no need to try to explode.

Xie Erjian, standing on a high place, couldn't help but secretly complain. It would be even better if someone strengthened and repaired it at this time, and it would be even better to raise the river a few meters. However, being able to trick the enemy into a fleet of thousands of people would be considered a reward for his decisiveness.

At this time, the sunset had already set. The river surface hundreds of meters long upstream had become a landslide lake. The lake surface was dyed blood red by the sunset. The river water overflowed from the "dam" surface and made a rumbling sound, but I still wanted to be imposing.

Xie Erjian glanced at the last sunset in the sky, then looked at the dam below, and it was still stable. It turned out that the Yangyuan stone lying across the river had the effect of the "Dinghai Sword Needle", and it was indeed firm enough.

So Xie Erjian finally decided to throw the remaining explosives down and blow up Yang Yuanshi.

With a loud bang, hundreds of kilograms of explosives made huge waves on the river again, but... the Yang Yuan stone was not broken, and Xie Erjian and Song Dayan were stunned.

"After all our explosives are used up. Why is this thing so tough?" A brother scratched his cheek and said anxiously.

However, as soon as he finished speaking, he heard a click. The Yangyuan Stone, which stretched across the entire river, finally could not withstand the pressure of the water flow and broke from the middle. The entire dam collapsed with a bang, and the surging river water rushed downwards and rushed downstream.

This place is only more than thirty miles away from the narrowest part of the downstream canyon, and it is just a matter of time at the speed of flooding.

It was already dark at this time, and before sunset, the Ming army in charge of the attack downstream had withdrawn from the canyon. This hour was when the Yarkand defenders had eaten dinner, so the river water had obviously become shallowered and no one noticed it. However, Xu Jin, a "mind person", sent people to monitor the changes in the river water, so the river water suddenly became shallower, and Xu Jin immediately knew.

Although Xu Jin made an appointment with Xie Erjian and had to wait for the second half of the night before taking action, the river suddenly became shallower before sunset. It was probably because Xie Erjian took action in advance, so Xu Jin immediately ordered the battle to be ready.

At this time, the narrowest part of the canyon, the five thousand Yerkand defenders were enjoying their dinner, and Bayi and Li Daren were no exception. They were drinking fine wine while eating mutton, which was not ordinary hapi.

The tents of the Yarkand defenders were all set on the river beach, and they were continuous for two or three miles. The surging flood suddenly came. The Yarkand soldiers who were having supper were swallowed by the flood without any time to react.

The first wave of the flood was the most destructive. It swept across the river beach for several miles, destroying all the tents with great force, and most of the defenders were involved in the river.

As Xu Jin said, starting from this, you must always start with it. The position of the defenders is exactly the narrowest part of the canyon. The defense is indeed very beneficial, but the flood becomes the most unfavorable as soon as it arrives. As we all know, when the flood passes through a narrow river channel, the water level will rise sharply and the flow rate will accelerate, so the probability of death of the defenders involved in the river will also increase greatly.

As soon as the flood rushed by, all the fires were extinguished. The canyon was pitch black, and only the rumbling sound of water, shrill cry for help, and sharp screams echoed in the canyon, making people creepy.

The open entrance to the lower canyon was brightly lit. Xu Jin had personally led the Ming army to wait for the battle. The river surface of several miles was illuminated by the fire as bright as daytime.

After the flood rushed out of the canyon, it quickly became smoother. There were countless tents, wood and other debris floating on the river, including a large number of corpses.

The Ming army naturally would not have the effort to salvage the enemy's corpses. They also looked down on those broken tents and rotten wood. On the contrary, if they saw survivors holding floating objects, someone would immediately shoot and kill them.

There was no way, the Ming army was blocked here for six or seven days, and two or three thousand people were killed and injured. Everyone was holding a breath. At this time, if they didn't take the opportunity to beat the dogs in the water, then when would they? What's more, the general also swore in public to wipe out the Yarkand defenders in the valley to comfort the brothers who died here, so the Ming army would not be ruthless.

The flood came and went quickly. In just about ten minutes, the water flow returned to normal, but there were still corpses and surviving Yarkand soldiers floating down the water.

With Xu Jin's order, Ordos general Mu Zixing personally led 5,000 people into the canyon. This was Xu Jin's chance to give him a penalty and a chance to avenge the soldiers of Ordos.

Let’s talk about Mu Zixing leading 5,000 people into the canyon and found that the defenders’ originally tight fortifications had been washed away, but some of the wooden stakes were still there.

Mu Zixing ordered the removal of wooden stakes, clearing out obstacles on the river beach, and starting to hunt down the surviving Yarkand defenders. Not to mention, there were really many survivors. Some of the fast-moving defenders climbed up the cliffs on both sides of the canyon, and some of them were lucky enough to hold the big stones on the shore and were not washed away by the flood.

However, these survivors were soon found and killed. The angry Ming army did not intend to capture prisoners at all, but they grabbed people and killed them on the spot.
Chapter completed!
