Back in Jinling, Xu You moved from the Shangshu Province to the Baihu Hall office in the General's Mansion and officially entered a wartime state.

He personally took the counterattack manifesto, listing Bu Tian’s despicable and shameless behavior of being unkind and unfaithful, unfaithful, unfilial, and treasonous, willing to be a slave of the country, and mocking the Wei Lord for his personal desires and vain the welfare of the people, unilaterally tearing down the Zhuluying Alliance, betrayed the faithful, and punished the contemporary heaven and the world to fight against it.

Then multiple decrees were issued:

The governor of Yuzhou, Zuo Qi, was appointed as the governor of the Northern Expedition, and held the ranks and commanded the troops.

He appointed the governor of Yanzhou Qi Xiao as the vanguard and immediately went north and led the Yanzhou army and Xuzhou army to station in Pengcheng.

He ordered Shanzong to be the governor of Xuzhou, led the Youdu army to arrive, met with Qi Xiao's troops, and went to Zuo Tu's tent to listen to the order.

The governor of Jingzhou, Tan Xiaozu, ordered the Jingzhou army to lead the Jingzhou army as a strategic reserve force and ready to support Zuo Shi at any time.

He ordered the governor of Luozhou Ye Min and the governor of Qinzhou Zhu Li to join forces to conquer Luoyang and advance the war to the north bank of the Yellow River.

Cao Qing was ordered to lead the central army to strictly guard Jinling and surrounding important towns to prevent unrest.

The company is responsible for the preparation of grain and grass and the manufacturing of military ordnance, and must ensure quality and quantity supply to the front line.

The governor's offices of each state were ordered to strictly monitor the movements within the territory, and prohibit gatherings of more than 100 people. Anyone who takes the opportunity to cause trouble will be sentenced to death.

...

After these four years of development, the Chu State's national strength has increased by leaps and bounds, and the treasury has been abundant. However, through the elite military strategy, the number of troops has dropped by 30%.

This time, the troops dispatched 80,000 troops to the Northern Wei Dynasty. There was no pressure on the logistics side and they could also improve their food from time to time.

This is the biggest advantage over the Northern Wei Dynasty.

When fighting, it is logistics, money and food, sustainability and the national tolerance.

In these aspects, Chu State won completely.

However, Qingzhou changed its flag and instantly the five counties fell. The front line of Chu and Wei advanced near Pengcheng. The two sides arranged troops and set up their formations. The situation was tense and was about to break out.

At the end of November, the Wei army took the lead in attacking from three routes, and the left and right routes were unstoppable, conquering Langya County, Lanling County, Gaoping County and Donghai County.

The middle route was led by King Chengyang and drove straight into Pengcheng, and stationed on the banks of Sishui.

Qi Xiao's strategy was to concentrate superior forces. No matter how many enemies came, he only went all the way. While the Wei army in the middle was not yet stable, he became arrogant because of the great victory between the east and west routes. He did not take the defenders of Pengcheng seriously, so he led 5,000 elite troops to cross Sishui at night and attack the Wei army camps.

The Wei army was not ready for defense and immediately became in chaos and retreated thirty miles in a hurry. In the crisis, all rely on General Yang Luan, the Zhendong, stood up.

He was over 70 years old and had a long beard and white beard. He was incompetent to ten thousand men. He was ordered to lead two thousand cavalry to break the back, rush into the Chu army formation with bare shirt, and fought three times. He was hit by an arrow on his legs, and broke the arrows, crossing the back of the horse, shouting: "Yang Luan is here, who dares to fight?"

The Wei army was very powerful and resisted the attack of the Chu army and had the courage to counterattack. Seeing that the situation was not good, Qi Xiao hurriedly withdrew his troops and returned to the city.

In this battle, killing more than 7,000 Wei troops in formation was considered a great victory. If Yang Luan had not been brave enough to win the three armies, he might have defeated the Central Army in one battle.

King Chengyang suffered a great loss this time, and then he fought steadily. When the three routes met, they forced their way through Sishui again and surrounded Pengcheng.

Then, Pengcheng failed to defeat for half a month.

After failing to succeed, Yuan Yu sent a stern decree from Yedu. King Chengyang was under great pressure. He ignored his dissuasion and moved the camp from the north bank to the south bank, only more than ten miles away from Pengcheng. He also built two wide wooden bridges in Sishui to connect the north and south and transport food and grass.

Then countless fortresses were built along the south bank, and they made up their minds to completely encircle Pengcheng.

Shanzong led the Youdu army to Xiapi, and got Zuo Qi's secret order. He pretended to be drunk and revealed the past when he was incompatible with Qi Xiao. Now he was so happy to see him laughing at him, so he stationed his troops without moving.

The Hou Guan Cao learned that he reported to King Chengyang. King Chengyang was very happy and no longer defended the Shanzong troops in Xia Pi with heavy troops, but once again gathered troops to attack Pengcheng.

But Pengcheng is like a wall of iron. The two sides fought dozens of times a day, but there was no progress at all.

The city was besieged for two months. By the beginning of the next year, the river ice thawed. Yang Luan was worried and said to King Chengyang: "Pengcheng has been fighting for a long time, and the three armies are exhausted. I think it is best to retreat. Return to the army first to consolidate the results of Qingzhou, and then go south to find opportunities for fighters. Otherwise, in the spring and summer, the rain will increase, and the Chu army will build dams upstream, and there may be unexpected disasters..."

The King of Chengyang hurriedly ordered people to monitor the hydrology, but there was no change at all. He sent a scout cavalry to patrol twenty miles along the river, and it was nothing unusual. He smiled and said, "The Si River is turbulent, and at least tens of thousands of civilians have to be recruited to build a dam, which took several months or even a year to work. By then, Pengcheng would have already given me a happy land..."

Yang Luan thought about it and it was reasonable, so the Wei army no longer paid attention to the upstream trends.

At the same time, while the main force of the Wei army was completely trapped in Pengcheng, Zuo Qi led the Yuzhou army not to walk on the road, opened the road when they met mountains, and built bridges when they met water. They moved fifty miles upstream of Si Shui without knowing it.

The Ministry of Industry sent a large number of graduates from Wuguanxue who were proficient in geography, hydrological observation and civil engineering to follow the army. Using steel bars, cement and bricks developed by Tiangongfang, it took only seven days to build a river dam upstream of Sishui.

Xiao Yan of another time and space built a Fushan weir in the Huaihe River, conquering more than 200,000 civilians, and more than 100,000 were exhausted, which took more than two years to complete. As a result, he was washed away by the Huaihe River in five months and drowned more than 100,000 people downstream.

The tofu project is a terrifying thing that harms the country and harms the people!

However, in this time and space, the historical process reversed. In March, heavy rains fell one after another, and the Si Shui surged. Zuo Ting ordered the dam to blow up at night, and the surging waves swept across the sky.

The two sides of Pengcheng were established as a Ze Kingdom, which not only destroyed the two wooden bridges built by the Wei army and divided the Wei army on both sides, but also fed half of the main forces of the Wei army who were besieging Pengcheng on the south bank to fish and turtles.

Fortunately, all the people around him had been moved into the city in advance, and the damage was not serious.

Zuo Qi immediately led the Yuzhou army to go down the river by dragon boats. Shanzong, who had been guarding Xia Pi for three months, also led the Youdu army to go up the river.

The two sides met and joined forces with Qi Xiao's troops in Pengcheng to first annihilate the remaining enemies on the south bank, then cross the Si River, fight bravely and bloody all night, and defeat the panicked Wei army on the north bank.

King Chengyang fled north in a hurry under Yang Luan's cover. The Wei army behind him was floating on the pillow for more than a hundred miles, and the Si River cut off its current.

Zuo Qi took advantage of the victory to pursue Xuzhou, conquered the lost numbers, and then attacked Qingzhou. Bu Tian's Qingzhou army also mutinized. Bu Tian was saved and fled to Yedu.

Upon hearing that the front line was tragically injured, Yuan Yu carried his sick body to recruit 200,000 troops from six states and went out to fight in person. He quickly stabilized his situation by the Yellow River and returned to his country with the defeated troops.

Zuo Qi also received Xu You's order. He knew that the Northern Wei Dynasty had a deep foundation and was not yet the time to destroy the country. He shook his martial arts and power on the south bank of the Yellow River, and ordered tens of thousands of people under his command to shout in unison: "The Lord Wei was changed to Yuanniang, and when he went home to embroider the flowers, don't talk about war."

Then the general was left to guard the border and return to the court.

In the Battle of Pengcheng, nearly 100,000 elite Wei troops were killed or injured, 20,000 were captured, and only more than 30,000 troops remained, and they were unable to move south again.
