Guan Yu refused to let Zhang Ji retain military power, and the entire army withdrew to the northwest to wait and see, giving up the conditions for Chen Cang City. Out of concern and hesitation, Zhang Ji had to stop seeking peace and defended himself.

There is no way, both sides have their own concerns and reasons to refuse to believe each other. The life gate cannot be handed over to the enemy at will.

Especially Zhang Ji and Guan Yu, there were major misjudgments on the issue of "If Chen Cangcheng strictly guarded, how long can it last?", which led to Zhang Ji's inability to evaluate how much the chips he had in his hands were worth. The negotiation conditions set out seemed to be ridiculous in the eyes of the Han army.

Three days after the collapse of the talks, everything was safe. Guan Yu continued to organize and destroy the peripheral fortifications outside the west gate and build siege equipment. On the other hand, Zhang Ji felt it was impossible to attack the main attack, and secretly took advantage of the night to construct the construction and arrange boats to dispatch troops.

There is nothing to say about the war on the fourth and fifth days of the lunar month. Apart from destroying fortifications, they are just shouting to attack the heart. Some rumors that are very unfavorable to the morale of the defensive party have gradually spread along with the calls of the siegemen and the small notes emitted by shooting into the city with powerful crossbows.

At first, Zhang Ji did not pay attention to the notes tied to the arrows shot into the city by the siege troops. Later, he found that the message was being circulated in the army, and realized the importance of unifying the people's hearts. He sent personal soldiers to search, which made people more and more panic.

Rumors like this spread wildly in the city:

"Have you heard that? The reason why the east of the city was flooded and the water became deeper and deeper, it was flooding into the Wei River. It was not spring rain or melting snow, or the Western Han Dynasty water was changed direction!"

"The Western Han Dynasty water has changed its route? We have never heard of where the Western Han Dynasty water is." Many ordinary soldiers have no education, and the Liangzhou soldiers have never been to Shu, so they don't know what kind of river the Western Han Dynasty water is.

However, as long as a group of soldiers has a few words of one or two lengths, or know a few historical stories, you can solve this question:

"I heard that it was originally flowing from Hanzhong to Chencang, and from here to the Wei River. It was the old lady of Empress Dowager Lu. After she and Emperor Hui, the eldest son of Emperor Gaozu, died, the hen crowed and took charge of the government affairs, and violated the White Horse Covenant of Emperor Gaozu's "not the king of Liu's surname."

Emperor Gao was furious in the sky, so in the second year after Empress Dowager Lu's old lady was in power, Wudu County was in a major earthquake and the mountains collapsed. The collapsed mountains blocked the way of the Han River flowing north. From then on, the dragon veins of the Han Dynasty flowed southeast to Jingzhou, in Nanyang County, Jiangxia County entered the Yangtze River, instead of entering the Yellow River from the Wei River to the Yellow River. This was the Emperor Tian Buzuo Lu family.

So Emperor Guangwu later revived the Han Dynasty and started in Nanyang. Nanyang County was also the place where the Han River flowed through! I have never read books, but I heard that these are clearly written in the Book of Han, and can they still be fake? If you don’t believe it, go and ask Cao Guan, who has read history books, as long as you have the courage."

"Really and false? This is too mysterious. Is there any other evidence?" The big soldiers were stunned when they heard this. They wanted to believe it but didn't dare, and they didn't want to believe it but were unwilling to give up. They would try to ask for some circumstantial evidence again.

But the evidence for this incident is still very sufficient. In the spontaneous game of the masses' wisdom, "iron evidence" have been spread again, strengthening the persuasiveness of the previous words:

"Why is there no? There is still a lot of evidence. Do you know what year the Wudu earthquake in Han Shu was? It was the '27th day of the first lunar month'. This time I heard that the Hechi Mountain collapsed, and it was also the 27th day of the first lunar month, but the river flowed to us at the end of the first lunar month.

Han Xin was able to secretly visit Chen Cang because he followed Emperor Gao of the True Dragon, and had the protection of Emperor Gao. Liu Bei heard that he had also had a dream in his mind. He clearly told Liu Bei that the day of the earthquake and landslide was spread throughout the camp in the opposite camp."

Such rumors spreading are getting higher and higher, and the panic of Chen Cang's defenders can be seen.

It must be clarified that the rumor formed this way, and it is definitely not the version that the person who originally spread the archery book wanted to spread. The original version is far less detailed and colloquial.

But rumors are like viruses. They can mutate themselves during the transmission process, and the more they spread, the more they change. Every word of mouth is the recreation of the translator with his own wisdom, and it will not be the same as the version he hears.

So after being spread for a long time, it will definitely be the most down-to-earth and logically self-consistent version, the most tenacious vitality, and the most heard - just like a virus, mutating more contagious and latent DNA, so that more contagious and hidden DNA can be passed down and squeezed out the infectious and weak concealing version.

The above exquisite rumors are the final version of the group wisdom of the soldiers in the city that iterates through the continuous iteration of creation, so it looks so vivid.

After Zhang Ji discovered this problem, he could only engage in a reign of terror, investigate the main evil, kill dozens of influential and nonsense people, and hang their heads on the city towers everywhere to show publication, which was considered to suppress the nonsense of the soldiers and ensure that only a few thousand of the 15,000 soldiers had heard such rebellious remarks that would hit the military.

But while killing the spreader of rumors, Zhang Ji himself became more and more afraid, because even he felt that the will behind this seemed quite real.

When he went to bed on the night of the fifth day of the second month, Zhang Ji was even awakened by a nightmare and screamed in shock.

He dreamed of the surrendered general of the Qin Dynasty, Zhang Han, who was defeated by Han Xin secretly in Chen Cang, was eventually besieged in Wuqiu and died by Han Xin's flooding. As he dreamed in his dream, Han Xin became Guan Yu, and Zhang Han became himself. The Chen Cang city wall in his dream was also soaked like the Wuqiu city wall. The flood surging in, and he was also killed by Guan Yu leading a warship into the city.

"General, are you okay? Is it a nightmare?" The close servant beside him woke up when he saw Zhang Ji screaming and came over to care.

"It's okay! It's okay! Don't talk nonsense!" Zhang Ji was in a dream and sweated in his cold sweat. He still had to hold on, so that the servants were not allowed to speak out.

After being disturbed by this, Zhang Ji had no intention of continuing to sleep. He always felt uneasy. He put on his armor overnight and took a team of soldiers to patrol the city again in the middle of the night. Even the soldiers complained and thought to himself:

If you don’t want to sleep, we still want to sleep. And the east gate has been flooded for several miles. What’s the best place to patrol? The water outside the east gate is wider than the Wei River and Yellow River. It’s not as good as any moat. There is still someone who can rush so far to attack the city? Even if you take a boat, you can’t attack from there.

Because the night was too dark, Zhang Ji couldn't come out, so he finally came to dawn. He was really sleepy, but instead fell asleep on the city tower at the East City Gate, wearing armor and falling asleep. The cold in the early February of the lunar calendar was almost 100% frozen cold.

Fortunately, Zhang Ji didn't need to suffer slowly by catching a cold, and he felt more painful.

On the sixth day of the second month, at the end of the Chen hour, it had been bright for a long time. Zhang Ji woke up on the city tower. He patrols the city until the beginning of the Mao hour, so he only slept for three hours.

After waking up, he ate something, rubbed his eyes, observed the situation on the battlefield, and found a lot of amazing things for him.

"Why are there a few earthen platforms coming out of the water two hundred steps outside the city gate? The water depth is more than half a foot there, right? It was not a high ground before. Could it be that Guan Yu had someone piled up the soil overnight? It must be that there were small boats coming and going to deliver things next to it! Hurry out, go out of the city to destroy and kill the civilians. No matter what they are doing, it is definitely not a good thing!"

Zhang Ji remembered last night's nightmare and intuition told him that no matter what Guan Yu wanted to do, it would be right to destroy it. Everything was against Guan Yu.

However, no one listened to him, and the officers just looked at each other: "General, the water outside the city is half a meter deep. Our army is from Liangzhou. We are not familiar with water wars, and there are no ships. There are only rafts temporarily tied with beams and pillars. How can we fight?"

Zhang Jibing was ignorant of the doctor: "Then let's shoot the arrow! Try the hardest crossbow on the city wall. Isn't it just over two hundred steps, and the crossbow can't be shot?"

Someone listened to this time, but the attempt was soon failed, because the crossbow could only kill people, but could not destroy the fortifications. The enemy used rammed earth and wooden pillars as fences, which could not be destroyed at all.

I waited uneasy until noon in my heart, and the answer was finally revealed. It turned out that Guan Yu pretended to destroy the peripheral fortifications in the dry area of ​​the west of the city in the past few days and built a trencher. In the end, he transported the semi-finished trencher to the east position by ship. He also transported several platforms to load the trencher, and then aimed at the southern section of the east side, which was soaked in water at the base of the wall.

The counterweight catapult cart has been built by Liu Bei's army for three or four years, but it was originally kept confidential and was only used in remote stations such as Shu. The external warlords didn't know much about it, but they should have heard of the wind and sounds. They vaguely knew that "Liu Bei's catapult was particularly powerful", but they didn't know the principle and appearance.

However, the scale of Liu Beijun's trench machine is also constantly developing and evolving. What he took out three years ago was only a single-headed stone bomb that was thrown out 70 kilograms at one time. Now it has been strengthened to throw 150 kilograms of kilograms, and its destructive power to the city wall is even more amazing.

To put it bluntly, 150 Hanjin is not an exaggeration. In history, the Mongols smashed Hui Hui cannons that broke Xiangyang City and Lin'an City, and recovered it from about 150 kilograms of stones, equivalent to 300 city kilograms and 600 Hanjin, so it is four times larger than Li Su's current goods!

The reason why Liu Bei's camp was so well prepared this time was because the city like Chen Cang and the ones to attack were taller and thicker than the walls of the mountain cities in Shu. As for Chang'an, there was only Meiwu. Compared with this, Luoyang Energy was all terrifying existences of "seven feet high and thick" in the city wall.

No matter whether the rammed earth in the city wall is hard or not, just thinking that the thickness is seven feet, which is equivalent to sixteen meters, few people will think that just by hitting stones of seventy or eighty kilograms can knock down the wall. At most, some of the top earth collapses and becomes lower.

Less nonsense, one hundred and fifty kilograms of stones may still not be enough to deal with the Chang'an city wall. It may take several days to deal with Chen Cang under normal circumstances. It has to take the chance to smash the dense firepower at a point in a row.

But fortunately, the southern section of the city wall on the east side of Chen Cang that Guan Yu is facing now is no longer the "normal Chen Cang wall".

First of all, the base of the city wall has been flooded from the 30th day of the first lunar month. Today is the sixth day of the second lunar month. It has been soaked for six days. The deepest water level is more than half a meter, which is equivalent to 1.5 meters in later generations, which is enough to drown Guo and Feng and Liu.

When Qin Shihuang destroyed the Wei Kingdom in history, Wang Ben dug the Yellow River embankment and flooded Daliang City (Kaifeng). The Yellow River was soaked for three months, and there was no need to do anything else, and the Daliang City Wall collapsed directly.

Chen Cang is not as good as Daliang. If he only relies on soaking, he would collapse after soaking for more than a month, but Guan Yu couldn't wait for that long.

So while he soaked the crispy puffs, he cooperated with the heavy catapult.

"Boom!"

"Hulong!"

Large stones roared over two hundred steps and smashed scattered on the Chencang city wall. In just half an hour, the bricks and foundation stones outside cracked and fell off, and were smashed to pieces, gradually revealing the rammed earth inside.

The texture of these rammed earth does not look like loess or kaolin used for rammed earth. Instead, many places are dark in color, and they all look like humus silt dug out from the river.

Including Guan Yu himself, he hadn't even remembered it until this moment. Before entering Sichuan five years ago, Liu Bei's army, Huangfu Song and Dong Zhuo's army joined forces to fight a battle with Han Sui between Wuzhangyuan and Chen Cang.

After Han Sui was repelled that time, Huangfu Song and Dong Zhuo were responsible for pursuing and expanding the results of the battle. Liu Bei's army helped defend the city for a period of time. Li Su was very kind and offered a wallet to not provide materials. He helped Huangfu Song repair the city walls on both sides of the northwest that were attacked by Han Sui for half a year and were destroyed.

It was just because Liu Bei and Li Su were not budgeted at the time, and contracting labor was already the limit and could not afford to package materials. They had to dismantle the high-quality rammed earth and stone on the southeast sides to repair the northwest sides, and then dug the black silt from the Wei River to fill it into the sandwich cores of the city walls on both sides of the southeast. There was no tofu project on the surface.

There was no bad intention at that time, and he just put himself in his shoes as the loyal ministers of the Han Dynasty, Huangfu Song and Dong Zhuo. Considering that their main threat was Han Sui, Chen Cangcheng's defense should focus on the northwest and neglect the southeast.

Besides, this matter has been five years. If the Xiliang Army has a little patience to farm, manages its own territory well, and often renovates the city walls, then you can find these tricks.

Who made Chen Cangcheng fight many times in the years since then? Only the ones who were attacked were indeed facing Han Sui's walls on both sides of the northwest? The southeast walls did not play a role in one time, nor were they destroyed by the enemy, so the hidden danger of this tofu shit was hidden so deeply.

To put it bluntly, if another siege comes to smash it once, it is equivalent to the hacker gang Killing Soft Company finding a backdoor loophole, which is a matter of immeasurable merit.

Since you have not farmed for five years, you can't blame Guan Yu.

"Crash!" With a loud bang, even Guan Yu himself felt incredible. Why did it take a long time to smash the wall? A large hole in the city wall was smashed to only about one meter at this location. Then, under the influence of water pressure, the wall collapsed, and soon all the water poured into the ground and rushed in.

"The soldiers with ships, the whole army took the boat to assault! They rushed in through the gap in the city wall that was smashed! This is the appearance of Emperor Gao again! It is the King of Hanzhong!"
