Gao Shun was forced by Xu Rong to retreat and hurriedly fled, Xu Rong's brigade of men and horses poured out and went straight to the soldiers of the trench operation to kill, the soldiers of the operation saw that Xu Rong's brigade of men and horses were killed, and they left the guy in their hands and ran away, Xu Rong's brigade of men and horses all the way to the side of the trench, Xu Rong couldn't help but be attracted by the fortifications of the trench, and was about to go down to investigate the reality, at this moment only heard a series of cannon sounds, shouting to kill the sky, two teams of men and horses suddenly appeared, and Zhang Liao rushed over with a large number of men and horses on the left, On the right, Guan Yu took a large group of men and horses to cover up, Gao Shun in the middle turned over again and killed back, the three people and horses rushed to Xu Rong's army together, like three winds blowing over, Xu Rong was taken aback when he saw this, the amount was not an opponent, and he hurriedly retreated, the three people intercepted and killed, Xu Rong blocked the formation and killed back, the three people and horses chased and killed very urgently, Xu Rong killed and injured countless people, Xu Rong was quickly trapped in the heart of the left and right, and the conflict could not be stopped, and he was sweating profusely and soaked with armor.

Just when Xu Rong was under siege, he saw Feng Yicheng once again kill a large group of people, the head of the general is Yang Fuye, this Yang Fu is a Tianshui Ji people, at this time only 20 years old, make a pair of steel guns, immediately saw Xu Rong was trapped and led a large team of men and horses to rush out to catch Xu Rong, the arrival of reinforcements made the trapped Xu Rong see hope at once, Xu Rong swinging the big knife soon revealed the encirclement, Yang Fu jumped on the horse to catch Zhang Liao to fight, the two horses intersected, the two guns were raised, and there were more than 20 battles in a row, Gao Shun pursued in a hurry, Yang Fu didn't dare to sell a flaw in love and pulled the horse back, and soon retreated to Feng Yi City, and when he arrived in Feng Yi City, he saw that the city gate was lowered all of a sudden. Guan Yu led the generals to the city gate, but saw that the arrows on the city were raining down. Guan Yu was forced to retreat

It turned out that in order to prevent Xu Rong from coming to sneak attack, Guan Yu had already made preparations. The subordinates set a trap and waited for Xu Rong to lead the troops to come, Xu Rong really couldn't bear the loneliness and led the army to come, but was suddenly attacked by Guan Yu, almost lost his life, Xu Rong, who fled back to Feng Yi, no longer dared to easily try on Guan Yu's trench fortifications, and began to continue to retreat, no matter how Guan Yu's subordinates challenged, Xu Rong was unmoved.

"How's the raft going?" Guan Yu asked Li Yandao.

Li Yan replied: "Tell the general!" Everything went fairly well, but there was a lack of materials. Now that half of it has been built, there is no material, and the next plan is blocked! ”

"This is easy to do, the mountain opposite Weishui is full of trees, and it is autumn now, can you cut down some trees to use as necessary materials?" Guan Yu said.

After hearing this, Li Yan replied with relief: "Great! If you have the materials, you won't have to worry about building a raft! ”

"If we want to speed up the progress, it may not be long before it will rain here, and we can't catch it blind then!" Guan Yu admonished.

Li Yan then replied: "No! ”

After Guan Yu finished questioning, Li Yan came to Chen Gong's side again and asked about the trench fortifications, and Chen Gong said to Guan Yu: "Everything is ready, do you see if the depth and width of this fortification are enough?" ”

After Guan Yu heard this, he saw that this trench was dozens of miles longitudinal and horizontal. The depth is more than one meter deep, and the entire man-made river has been created, Guan Yu asked Chen Gong after reading it: "How about digging here, right?" ”

"It's so easy to dig, the surface here is washed by the river. The bottom is all sand, and the soil is soft and saves time and effort to dig, otherwise how can it be so fast? Chen Gong explained.

After hearing this, Guan Yu then asked, "This meter deep is full of sand?" ”

"Most of the sand layer is followed by the soil layer!" Chen Gong then replied.

Guan Yu nodded after hearing this: "God really helps me!" ”

He personally surveyed both of these fortifications. Guan Yu's heart has a bottom, and taking Feng Yicheng is just around the corner. And if Feng Yi is taken, Chang'an will be close at hand. After taking Chang'an, will the entire west be far away? And after the unification of the west, there will be a stable rear can stride eastward, I don't know how the war in the east of the road is, at that time Yuan Shao was called to recruit Cao Cao, I don't know what the results of the battle in the road are, but no matter what, as long as Yuan Shaoken sent troops is a good thing, it can put pressure on Cao Cao, Cao Cao did not dare to do Luoyang's plan, as long as Luoyang is fine, he can rest assured to conquer Li Dao.

Soon, as Guan Yu expected, Feng Yi's rainy season came again, this is the last rainy season in the local area, that is, the most rainy autumn rain has finally arrived, after this autumn rain Feng Yi will have no rain, that is, after this autumn rain, if Guan Yu does not seize this rare opportunity, then his plan will be in vain, but fortunately, Guan Yu still firmly grasped the last glimmer of hope, this autumn rain is very fierce, although it is not as lightning and thunder as in summer, wind and rain, But the rain poured down from the sky, and the river rose sharply.

At this time, Guan Yu has already built a thousand rafts, and the previous trench has already been dug up, just waiting for the rain to keep falling, this autumn rain is like a roar after the most reluctant, crackling and non-stop, it has been raining for three days and three nights in a row, and it still does not stop, it is still falling, this time the rain is more violent than Guan Yu expected, exceeding the expected effect, Guan Yu saw that the rain is not small, so he arranged for people to brave the rain to introduce the Weishui River and Luoshui into the trench dug in advance.

The autumn rain crackled and fell, and the whole space became a white patch, and something could be seen faintly, but it was blurry, the earth was hit by the rain and smoked, the whole suburbs were already muddy, the water of the Weishui River became more rapid, roaring and rushing into the distance, and then a group of people outside Feng Yi City were busy, holding the tools of digging in their hands and working nervously, their goal was to open the river channel in the north of the Weishui River, The water of the Weishui River was introduced into the trench dug before, but the team of hundreds of people was under the command of a person, wielding tools and constantly churning, a tall and mighty body in the crowd was particularly eye-catching, he gestured from time to time, and kept shouting, this person is Guan Yu, he came to the Weishui River together with the corporal to personally supervise and direct the excavation work, his scheduling is very in place, each process is commanded in an orderly manner, in Guan Yu's view, this is not only an excavation work but also a battleIf this is done successfully, then hope is not far away

The raging rain continues to devour people's clothes, the rain keeps slapping people's bodies, Guan Yu's face and body have been soaked with continuous dripping rain, but at this time he doesn't care about this at all, now he is too busy to get around, this fortification must be completed, the more the better, otherwise the river flooding will be out of control, so this task is more like a flood fight, we must buy time, improve efficiency, fortunately Guan Yu is an expert in this area, Before his rebirth, he went deep into the front line of flood fighting and rescue many times as a fire officer, and he was very familiar with this work, and Guan Yu, who had experienced how many times he had been honed like this, commanded this "flood fighting and rescue" with ease, and it seemed that he really responded to the sentence "Yiduo is not pressing", if you don't understand this, you are bound to be blind in this matter.

Under the strong command of Guan Yu, the river trough north of the Weishui River was quickly opened, and the river rushed to the trench that had already been dug like a floodgate, and soon filled the trench, and the river water of the Weishui River was introduced into the trench under the successful command of Guan Yu, and then waited for the news of Luoshui, but at this time, Guan Yu was already in a hurry, where can he wait!

After completing the introduction of the Weishui River, Guan Yu went straight to the direction of Luoshui non-stop, where Chen Gong was supervising and commanding, Chen Gong is a smart person but still very limited in terms of skills, so the command is not very effective, the excavation work of Luoshui is relatively slow, compared to Guan Yu rushed to Luoshui, Chen Gong is still busy nervously, but his command is really not very efficient, the water level of Luoshui is different from the downstream of Weishui, once skyrocketed, and the officers and soldiers sent did not have a good transfer, There is always where you need to be blocked, and you always miss the point.

Guan Yu's timely arrival solved everyone's urgent needs, Guan Yu saw that the situation in Luoshui was different from Weishui, and it was more complicated than the situation in Weishui, but he soon had an idea, changed the previous strategy, and used the previous strategy upside down. Because the water level of Luoshui is very high, the terrain of the river trough is also very steep, the slope is high, it is not easy to construct, and the rain is very large, and the difficulty of construction is further increased, so Guan Yu changed this situation, he decided to start from the trench, directly open the trench, let the trench pass in the direction of the river trough, and open up to the river trough of Luoshui, as long as the trench and the river trough are opened, Luoshui can successfully flow into the trench to complement each other with Weishui.

Guan Yu made up his mind after studying and began to command, he calmly dispatched, allocated manpower, gave orders, the entire construction began to be carried out in an orderly manner, the soldiers were no longer in a hurry, everyone had a clear goal, so that the efficiency was greatly improved, Chen Gong did not have Guan Yu's professionalism but was smart and many things were thorough, Guan Yu told him how to do it, he soon came to command his soldiers to do it according to Guan Yu's wishes, so that the two people cooperated with each other and quickly opened up the passage between Luoshui and the trench, Luoshui quickly filled the trench and spread out along the river, so that the two rivers were interconnected with the trench, and the entire east of Feng Yicheng became a man-made river.
