Guan Yu saw that the trench was opened, so he commanded the sergeants to start filling the east side of the trench with sandbags that had been prepared, for a time tens of thousands of officers and soldiers were like ants swarming to the trench, one person carried a sandbag and rushed to the trench, throwing sandbags to the east of the trench, and soon the east side of the trench formed a sandbag cast "big lift", the height of this "embankment" is two meters, the purpose is very clear is to block the water flowing into the trench from leaking out, so that Shadaizi forced the river to rush to Feng Yicheng, The entire Feng Yicheng and Zhuti are all filled with river water Guan Yu saw that the preparations had been completed, so he led his men to go straight upstream, at the same time thousands of rafts were all on standby, just waiting for the upstream embankment to open the breach and then rushed up, Guan Yu took the soldiers to the confluence of the two rivers upstream, came to the embankment here, but saw that the embankment was still the same in the wind and rain, strong and ruthless, Guan Yu led the soldiers to climb the embankment, and commanded again, he ordered the soldiers to open the opening from the side of the embankment, Don't open too big, fill a fortification with sandbags near the embankment, the other side of the mouth is a mountain, and it will not be washed down, and this side is filled with a berm fortification to protect the embankment because of the breach and not be expanded, so the breach was opened, only to see a flood of the brain snatching the way out and rushing straight to the bottom of the river, a stream of floods surging in large numbers, can't wait to rush away, the water is very fierce, straight to the downstream of the river.

The upstream embankment was torn open, and the water potential suddenly increased, constantly rushing to Feng Yicheng in the lower reaches of the city, and soon the water potential rushed to Feng Yicheng. A sergeant had already reported that Xu Rong had come, and Xu Rong was puzzled when he heard it, and said angrily: "Fart." How is it possible, how can the flood sink under Feng Yicheng? ”

However, under the strong persuasion of his subordinates, he still came to the west of Feng Yicheng to investigate. But seeing that the city was already in the shape of an ocean, the entire west of Feng Yicheng was full of floods, and the water level was still rising, Xu Rong was stunned when he saw this, his intuition told him that things were not good, there was actually a flood in the west of Feng Yicheng, it must have been caused by the breach of the embankment upstream, otherwise it would not have been able to flood the west of Feng Yicheng with these rains.

Xu Rong finished surveying the west of the city and then moved along the west of the city to the east of the city, and the scene in the east of the city shocked him again: he saw that the east of the city was also an ocean. Not far from the east of the city, a large embankment can be faintly seen standing upright, the entire flood has surrounded Feng Yicheng, the water level is constantly rising, Xu Rong panicked when he saw it, if it goes on like this, shouldn't Feng Yicheng be flooded by the flood? He was not worried about the water in the east, but he was worried about the water in the west, and if the levee was opened, the city would be like a levee downstream, blocking the flood water pouring upstream. The flood water will grow higher and higher, and there is an artificial levee in the east to block the river, but the artificial levee is limited in height, so as long as the flood level does not exceed the levee, the flood will pour down again. It doesn't pose much of a threat to the city.

Xu Rong is worried that the flood level in the west of the city is constantly rising, so that it will flood the city, and the rain at this time is gradually getting smaller, but it is still sparse and non-stop, and the water level of the flood is surging up one by one, and it will soon be beyond the city gate, and it will be forced upward. Water has seeped into the city, and the water level in the east of the city is still rising. The vigilance in the distance seemed to have increased a lot, and Xu Rong couldn't help but worry. He wondered, why did the water keep rising? It's weird

It turned out that Guan Yu saw that the water was too fierce and felt that the height of the guard was not enough, so he beckoned the people to continue to increase the height of the guard, so the guard was raised to nearly three meters, which was enough to block a lot of floods, the height of the guard was three meters, and the flood entering the city was only one meter, because the terrain of Feng Yicheng was relatively higher, and the river was forced to pass and there was a certain resistance, at the same time, Guan Yu's more than 1,000 rafts and wooden boats were already ready to go, seeing that the flood had poured into the city, Guan Yu then ordered the upstream to seal the gap, The breach of the previous embankment was sealed again, and once the gap was sealed, the water potential was suddenly reduced.

Guan Yu saw that the time had come, so he ordered the raft to attack the city, but suddenly saw more than a thousand rafts and ships have flocked to Feng Yicheng, this raft is all the whole Ge Dai Jia, each raft is equipped with more than ten people, so that there are more than 10,000 people in the team to attack the city, at this time Feng Yicheng has been completely soaked in water, all the people are not in the water, the flood is not over the waist, but it will not pose a threat to people's lives, people can move forward in the water with difficulty, so that the soldiers defending the city will be bitter, and there is no resistance under the city at all, Guan Yu's soldiers rode a raft upstream, carrying a large amount of firewood, grass and shields, as well as siege equipment, and went straight to Feng Yicheng to kill, among which a few wooden boats in front of them were specially used as vanguards, and a few were command boats taken by the generals, and the rest were all rafts, and the army besieged Feng Yicheng mightily.

Chen Gong and Guan Yu were on the same wooden boat, and Chen Gong said to Guan Yu: "Yun Chang must not be in a hurry to attack the city, it is better to be patient!" ”

"What do you mean by that?" Guan Yu stroked his beard and asked.

Chen Gong analyzed: "Now the flood has seeped into the city, the water potential in Feng Yi's city must be not small, it is a good opportunity for us to attack the city, but although the city is trapped by water, the city defense on the city has not been affected at all, the personnel and equipment are in good condition, if we take it rashly, we will have to pay a heavy price, but wait a little and then say, if the water continues to spread, the people under the city will definitely rush to the city in a panic, and then the city will be in chaos, at this time Xu Rong has no time to deal with us, If we attack the city like this, the people in the city will rush to climb onto the raft when they see a raft coming, and this will bring a lot of inconvenience to our attack! ”

"Ha Lu Ha Ha Gongtai said is reasonable, now the initiative is mine, we can control Feng Yi's affairs, these remnants have now become a turtle in the urn, sooner or later it will be the meat in our mouths, as Gongtai said, we don't need to rush to attack the city this time, just create momentum for Xu Rong, put pressure on them, now they are already defeated, we will eat him sooner or later, but in order to reduce casualties, we can slow down, but we have to put pressure on them, and it will change later, as long as the pressure we cause is big enough, the soldiers in the city will inevitably mess up, Even if the officers and soldiers do not disturb the people in the city, they will not sit idly by, and they will definitely take action, as long as there is a commotion in the city, it will be much easier for us to attack the city again! Guan Yu explained.

Chen Gong continued: "In the current situation, what we do is reasonable, but how to exchange victory at the minimum cost is a crucial one, what Yun Chang said is very reasonable, creating some psychological pressure on them, it is particularly important at this time, the general is worthy of being resourceful!" Admire, admire! ”

After hearing this, Guan Yu continued: "The Art of War: Fiction and Reality, Reality and Fiction, Falsehood and Falsehood, Truth and Falsehood, Truth and Falsehood, the philosophical principles in this are really the same!" ”

The two of them said as they drove the boat towards Feng Yicheng

But it is said that Xu Rong saw that the water under the city was constantly spreading, it had been beyond his waist, the city was in a mess, a lot of grain and grass were all flooded, the officers and soldiers who defended the city were soaked in the water and still guarded the city gate, and the people under the city suddenly became refugees and gathered to the city, and the officers and soldiers continued to block, but at this time, the refugees gathered more and more, and the officers and soldiers resisted very hard, and they were surrounded by refugees and kept retreating.

The grain and grass were flooded, the refugees gathered more and more, and things became more and more unfavorable, Xu Rong was very anxious, what should I do? Just when Xu Rong was melancholy, he heard the gongs and drums outside the city, shouting and killing the sky, as if there were thousands of troops and horses killing the generals, Xu Rong was shocked when he heard it, and hurriedly waited for the city tower to watch it, it didn't matter when he saw it, but he saw hundreds of rafts on the water outside the city swept towards Feng Yi, the rafts were neatly arranged with soldiers, some rafts also set up flags, straw was piled up in front of each raft, the soldiers held shields in their hands, held sharp weapons, and looked at Feng Yicheng to kill the future, not only the entire Feng Yicheng in the east of the city was surrounded, There were Guan Yu's men and horses everywhere, Xu Rong couldn't help but be furious, and hurriedly ordered the city to release arrows, and suddenly the archers in the city began to shoot arrows to the city in turn, and for a while, the arrows in the city rained down.

The raindrop-like bow and arrow shot at Guan Yu's sailors, Guan Yu smiled when he saw this, and then made a gesture to the flag bearer, the flag bearer quickly understood, and soon blew the horn, after a trumpet, he saw that thousands of ships all turned the bamboo raft in unison, and the side of the piled firewood and grass was towards Feng Yicheng, so that when the raindrop-like bow and arrow came, they were caught by the straw piled up on the raft, and these straws were all tied upright, like a scarecrow tied to the raft, compared to the bow and arrow. All of them were intercepted by the scarecrow, and they fell on the straw with a crackle, but the real soldiers hid behind the scarecrow and covered the bows and arrows with their shields, and the archers in the city kept shooting, and the scarecrows on the raft were soon covered with bows and arrows, densely packed

Xu Rong saw that all the bows and arrows shot out of the river were all for Guan Yu to know that Guan Yu had fallen on Guan Yu's tricks, and he was really sad and angry, because of the flooding of Feng Yi, he was already anxious, and this time he was exploited by Guan Yu again, and he was so angry that he was so angry that he couldn't do anything for a while, Yang Fu saw that Xu Rong was angry and his mind was blank, so he said Xu Rongdao: "Guan Yu's attack on the city is fake, the purpose is to create pressure on us, and use this momentum to create panic in our hearts!"
