Of course, what made Xiao Yi most uncomfortable was the disturbance made by Northern Qi outside the city.

The walls of Jiangling are towering and magnificent, and there are Jingnan soldiers mobilized by Xiao Yi in the city, and the garrison is sufficient, Gao Cheng did not have the idea of attacking the city from the beginning, and while waiting for the news of the battle of Anlu, the civil engineering work that should have been left has not fallen.

For example, after Gao Cheng's army arrived at Jiangling City, he mobilized the people to build Tushan in the east of Jiangling City, and because there were 20,000 remaining cavalry guards to protect it, the Liang army could only watch the Tushan outside the city rise above the city wall little by little.

On July 27 of the second year of Zhaode (549), on the fourth day of Liu Zhongli's escort to the city of Gangneung, he besieged Gangneung for more than 20 days, and the Northern Qi, which had finally completed the Tushan operation, immediately launched an offensive.

Since Tushan was in the east of the city, they attacked mainly from the east, and the archers of the Northern Qi Dynasty climbed Tushan and shot arrows condescendingly, suppressing the defenders on the city wall, and the people were able to fill the moat relatively safely.

The moat was filled, Gao Cheng immediately sent state and county soldiers to attack the city, and the momentum was very loud, but even if the Liang army defending the city was suppressed by the Tushan archers, the Northern Qi siege troops could easily approach the city wall, but the city guards were also concentrated in the east, and they attacked the city for several days in a row, and they could not succeed.

On the third day of the eighth month, watching the Northern Qi siege troops retreat back like a tide again, Gao Cheng's face was calm, and even with a hint of joy, the reason was that Li Bi had just reported that the tunnel had been dug under the Jiangling city wall, and now the towering Jiangling city wall was only supported by wooden pillars, and the soil under it had long been hollowed out by the Qi army.

The Murong family's lure the enemy to set up an ambush to learn, and the Gao family's ability to dig tunnels cannot be lost, Gao Cheng's father Gao Huan used this method to collapse the city wall of Yecheng, thus attacking Yecheng, Gao Cheng also used it when he was besieging Nanjingzhou seventeen years ago.

The siege of the city in the previous days was just to cover up the movement of the underground operation, and there were archers on the earth mountain to suppress the defenders of the Southern Liang, and the siege troops who dug tunnels to cover the city could also reduce casualties, and at the same time, the earth mountain could cover the sight of the Liang people, and the Northern Qi cavalry also covered the tunnel operations behind the earth mountain in the name of protecting the earth mountain.

Let's try it soon, everyone. 】

The key to the success of the tunnel lies in whether it can hide from the eyes and ears of the enemy defending the city

"Your Majesty, do you want to set fire to the stakes now?"

Li Bi asked.

Nine years ago, in the Battle of Guanzhong, Li Biyi turned his back on Hou Mo Chen Yue so before, surrendered to Yu Wentai, and surrendered to Northern Qi.

Gao Cheng knew his talent, but he also knew his nature, so he stayed by his side and became a governor of the account, the so-called governor of the account, that is, a general who can participate in military discussions, but has no troops under his command.

Li Bi complained a lot about his situation, but he didn't dare to say anything to others, this time he finally got an errand from Gao Cheng, responsible for digging tunnels, and even more energetically, lest he leak the news, and now his hard work has finally paid off.

Gao Cheng saw that the sky was about to get dark, so he didn't agree, and the Northern Qi army returned to the camp one after another, leaving only part of the army to take turns guarding Tushan.

The defenders of Nanliang at the head of the city have only then relaxed, in the past, they were condescending to defend the city, but now they are reversed at two levels, and from time to time arrows are lost in the head and fly wildly, and they are suppressed so that it is difficult to raise their heads, but fortunately, the Qi army's siege is not strong.

Wang Seng was suspicious in his heart, and reported to Xiao Yi, but Xiao Yi didn't think he knew:

"The high thieves are good at attacking the city with state and county soldiers, and they always suffer heavy casualties, but the reward is lower than the soldiers, and the morale of the besieging people is low, so they are naturally unwilling to fight to the death."

On the fourth day of the eighth month, it was only three o'clock in the morning (three o'clock in the morning), Xiao Yi, who was sleeping sweetly with his pet concubine in his arms, was awakened by a loud noise, and the sound of killing came from afar outside the city.

"What's the matter! What happened! ”

Xiao Yiguang got on the bed and came to the courtyard and howled.

Soon Wang Seng ran over and said with a sad face:

"My lord, several sections of the eastern city wall have collapsed."

"Then don't you hurry up and plug it!"

Xiao Yi said urgently.

"It can't be blocked, the Qi people have already prepared, and they lined up at night, while the soldiers of our army are resting, the city wall collapsed, and it didn't take long for the Qi people to rush in along the gap, and there was no time to block it!"

Wang Sengbi explained, and then Du An, the mastermind who came over, urged:

"The city wall has fallen, Jiangling is difficult to defend, the body of the king's daughter, you can't take risks lightly, it's better to get on the boat first and leave through the water gate."

There are two water gates in Jiangling, one is in the north of the city, there is a wide river dug by the population in the north of Jiangling City, and the other is in the south of the city.

Just when Xiao Yi hesitated, he suddenly heard a report that a large number of Northern Qi cavalry were coming to Xiangdong Wangfu, and it turned out that Gao Cheng ordered the foot soldiers to enter the city along the ruins of the collapsed city wall, so he seized the east gate, let the cavalry enter the city, and led the way along the avenue to the Xiangdong Wangfu.

In such a critical place as Gangneung, Gao Cheng has not been less meticulous, although it is night, but there will never be any troubles that make the wrong way.

When Xiao Yi heard this, he was shocked, not to mention burning books, he couldn't even take care of his wife and concubine, so he fled to the south of the city under the escort of Wang Shengbi, Du An and others and the guards.

When Xiao Yi got on the boat that had been prepared for a long time, left through the south water gate, and glanced at Jiangling City behind him, he could vaguely hear the exclamations of the people and the shouts of the soldiers.

But before he had time to take a breather, there was a Northern Qi Naval Division that had already been ambushed to kill him, if it wasn't for the timely rescue of the Jingxiang Naval Division and the repulsion, I was afraid that Xiao Yi would really not be able to escape.

In this world, like Wang Zhen, when the enemy army enters the city at night, there are only a few deeds of wearing hair and bare feet, and holding a wooden stick to repel the enemy army, otherwise Sima Ziru will not hold a grudge, and in the case of Gao Huan's intention to surrender, he will slander and kill Wang Zhen.

After all, this kind of thing is indeed shameful enough for the siege troops.

After Gao Cheng led the army back to the camp before, except for the patrol troops, the rest of the soldiers rested, which was the idea of attacking the city in the middle of the night.

At three o'clock in the morning, when the sleep was deepest, the city wall suddenly collapsed, and the Liang army did not have time to react, so it could be poured into the city by the prepared Qi army, which was the same as attacking the enemy camp at night, that is, using the enemy's panic to win.

Xiao Yi and others have taken advantage of the chaos to flee, and the Liang army, which was finally assembled in the city, under the leadership of the generals, took advantage of the night to escape, but after the panic of the people of Jiangling at the beginning, they saw that the Qi troops passing along the way did not loot, but most of them returned to the house, but closed the door.

The turmoil in the city quickly subsided, and the Northern Qi soldiers who poured in one after another guarded all the important places in the city, and at dawn, Gao Cheng entered the city surrounded by everyone.

He didn't stop along the way, and rushed straight to the Xiangdong Palace, at the moment when many sections of the city wall in Jiangling East City collapsed, this battle was no longer suspenseful, and he was more concerned about the more than 80,000 books that Xiao Yi had in the city.
