On the seventh day of the siege of Yijing City by the Wuke Army, the embankment above Yishui was also built.

From Yishui to Yijing, and then to the mound in the city; From the Liangzhou military camp to the city, and then to the tunnel under the mound in the city, it has been completed.

With the construction of the Yishui Dam, the amount of water flowing into the city of Yijing is decreasing day by day.

At first, Gongsun Zhan and his civil and military forces did not pay much attention to it, but it was caused by the drought in early spring, and the flow of easy water became smaller.

But for three days, the water flowing into the city became less and less, not to mention the water used by livestock, and even the water used by people was no longer enough.

Since Gongsun Zhan stuck to Yijing City, he no longer sent scouts out of the city to inquire about the news; What's more, with the siege of the Liangzhou army, the scouts of the Youzhou army could not leave the city at all.

Therefore, the Liangzhou army blocked the water to build embankments and dig tunnels, and the Youzhou army naturally did not know.

Just when Gongsun Zhan and his civil and military forces were puzzled, Guan Jing was the first to react...... The Liangzhou army intercepted the water and built a dam, which was going to flood the capital of Yijing.

When Guan Jing told this speculation, Gongsun Zhan and Youzhou Junwen and Wu realized the seriousness of the situation.

Without water, no amount of food and grass in the city could sustain them.

However, Gongsun Chan was not afraid of the Liangzhou army flooding Yijing. Because the city has a perfect drainage system, no amount of water can flood the city.

It's just that what Gongsun Chan doesn't know is that the "insidious" Liangzhou Army has long blocked all the sewage outlets outside Yijing City.

The problem of water source has become a big problem for Gongsun Zhan!

Guoyuan Jinyan Gongsun Zhan...... Led the troops out of the city, attacked the Liangzhou army stationed on the embankment, and then took the opportunity to destroy the embankment.

Guan Jing, who was well aware of the sharp combat power of the Liangzhou Army, retorted with his words...... Since the enemy army can build a dam on top of the easy water, it must be prepared to prevent a sneak attack.

Before the Youzhou army retreated to Yijing City, it had already folded nearly 30,000 soldiers and horses, and Gongsun Zhan had long been frightened, so he naturally did not dare to lead his troops out of the city.

When Guan Jing had a flash of inspiration, he thought of a solution to the water source...... Dig a deep well in the middle of the city.

The soldiers of the Youzhou Army, who were about to die of thirst, immediately took action impatiently, and after digging five feet into the ground, they finally dug out the groundwater.

When the problem of water was solved, Gongsun Chan made up his mind, and he no longer had any worries, he could continue to stick to the city, and he could continue to sing and dance with his wives and concubines.

People have no long-term worries, but they must have near-term worries!

Within two days of the Youzhou army's peace of mind, the city began to stink. However, they still don't know what the reason is.

On the third day, the entire Yijing City was covered and permeated by a foul smell, and sewage slowly appeared at the sewage outlet in the city.

Soon, the Youzhou Army reacted, and the insidious and vicious Liangzhou Army blocked the sewage outlet outside the city.

The sewage channel could not be dredged, and the Youzhou army had no choice but to dig ditches and large pits in the city to channel the sewage into the deep pits.

On this night, the Liangzhou army outside the four gates of Yijing City pulled out the camp and retreated, and set up the camp on the high ground outside the city.

Also at the end of the day, the Liangzhou army dug the embankment above the easy water.

The rolling torrent with the overwhelming momentum of the mountains and seas, surging and surging, the huge waves are surging, sweeping and rushing down from the upper reaches of the easy water, if it is a galloping horse, it is like an evil dragon roaring.

When the flood rushed to the bottom of Yijing City, the water depth of the flat land was five zhang deep, and the entire Yijing City was surrounded by water.

The tunnel dug by the Liangzhou army was already filled with floodwater. 520

The mounds in Yijing City, except for the one where Gongsun Chan was located, were only five or six zhang.

Since then, the water surface that has spread is either more than the camp of the Youzhou army... One foot lower, or level with the enemy's barracks.

The Liangzhou army dug the embankment late at night, and the Youzhou army in the city was defenseless.

The enemy troops stationed on the barracks suffered no losses; The enemy troops stationed under the camp were all flooded, and none of them survived.

Set up a raft at night, and the Liangzhou army formed a formation in all directions outside Yijing City.

The Liangzhou army did not attack the barracks on the mounds in the city, but only besieged them.

The raft can't hold up the stone cart, but it can support a giant crossbow machine.

Besieged on the raft around the mound, the Liangzhou army shot the Youzhou army in the camp with giant crossbow arrows, crossbow arrows, and armor-piercing crossbow arrows.

In less than a day, most of the Youzhou troops stationed on the mound chose to surrender. There are dozens of camps surrendered by the Youzhou army.

The generals Tian Kai, Shan Jing, Wang Men, and Fan Fang under the command of Gongsun Zhan were all wiped out by the Liangzhou army when they led the troops to break through, and none of them survived.

At this time of great danger, Gongsun Chan did not let Guan Jing, Guoyuan, Yan Gang, etc. Retreat to his mound.

On the third day, except for the mound of Gongsun Zhan, all the Youzhou troops in the camps above the mounds surrendered to the Liangzhou army.

Seeing that the general trend had gone, and seeing that Gongsun Zhan was not saved when he saw death, the disheartened Guan Jing, Guoyuan, and Yan Gang led their troops to surrender to the Liangzhou army.

On this very day, the flood waters slowly receded, and all the small mounds, soaked in the water, collapsed with a bang.

Seeing this scene, those soldiers of the Youzhou Army who surrendered, while having palpitations, were secretly happy.

If they did not surrender, they would either fall to their deaths or be hacked to death by the Liangzhou army.

Although the mound where Gongsun Chan was located did not collapse, it was also in a precarious and crumbling state.

Zhang He once asked Guoyuan and Guan Jing to call out to Gongsun Zan to persuade him to surrender. But the fierce and brave Gongsun Chan refused to surrender.

The Liangzhou army assembled nearly 100 stone trucks around this mound more than ten zhang high, and bombarded them day and night.

At dawn the next day, Gongsun Zhan, who would rather die than surrender, saw that the general situation was gone, and took his wives and concubines to self-immolate in the camp.

Gongsun Zhan's younger brother Gongsun Fan, Gongsun Zhan's son Gongsun Xu, chose to kill himself. Gongsun Zhan's younger brother, Gongsun Yue, died at the hands of the Jizhou army a long time ago.

The Liangzhou soldiers attacked this mound without blood, and beheaded Gongsun Zhan, Gongsun Fan, and Gongsun Xu.

On the same day, the Wuke Legion took the heads of Gongsun Zhan, Gongsun Xu, and Gongsun Fan and marched eastward.

Within two days, the three counties of Youzhou Yuyang, Youbeiping, and Liaoxi were all captured by the Liangzhou army.

The Wuhuan people in these three counties, afraid of the momentum of the Liangzhou army, fled in the hope of the wind, or fled to Liaodong County, or fled to Saiwai.

The Liangzhou Army occupied the strategic point of the Liaoxi Corridor, and could attack Liaodong County in the east and the northern expedition outside the Saiwai; The counties in the western part of Youzhou can be retained.

The Wuke Legion is stationed in Youzhou!

Half a month later, Li Yan, Liu Bi, Ling Bao, Deng Xian, Guan Jing, Yan Gang, Guo Yuan, and 60,000 foot cavalry to guard Youzhou, Zhang He and Wutu led 10,000 troops to join the Canglong and Wuqian Legions.

Youzhou is included in the rule of the Liangzhou Army!
