Zhang Liao ordered to hold on to Nanpi City, and he also held the camp tightly and restored his morale first.

Tang He did not rush to attack, but began to build siege equipment. Tang He and Xue Rengui chose to release the siege of the city, he did not make too many trebuchets, but directly chose to attack with negative soil. However, his negative soil attack on Xue Rengui was not the same, but he directly built hundreds of cars, filled the cars with soil, and pushed them directly into the moat, filling the moat. And push it under the city with a car, which saves a lot of time.

It took too long to attack the soil, but Tang He was not in a hurry, after all, there were many soldiers in the city, and a little consumption was also needed.

Su Lie crossed the river from Eping, but was also blocked by Lejin. Le Jin is a fierce general, and he is also a fierce general who is very good at attacking the city, and he often climbed the city first in his early years. He is an offensive general, so he personally led the team in Liaocheng to prepare for a half-crossing attack.

But they encountered the same problem as Cao Ren, that is, in the face of the attack of the opponent's crossbow arrows, they could not prevent the other party from going ashore at all. They all seemed to have forgotten the strength of Zhang Yi's warship attack. However, Cao Jun seems to have not seen Zhang Yi's warship for a long time, and the last time it seems to be in Nanyang.

In the first Northern Expedition five years ago, Gan Ning's navy only blocked the river in the plains, but did not engage in many battles, and they all subconsciously ignored this matter, only Zhang Liao remembered.

Lejin suffered a wave of attacks, so he quickly retreated to Liaocheng, and it was really a loss to fight by the river.

Liaocheng is only a small county, and Lejin is stationed here just to prevent the army on the other side from crossing the river, and now people are lining up by the river, but he can't go up to fight, and the role of defense in Liaocheng does not exist. Lejin hurriedly retreated to Ganling in case he was pursued by enemy cavalry after the city was broken.

Su Lie directly marched into Liaocheng and sent Zhang Xiu to the west to recover Leping, Fagan, Yangping, and Dongwuyang, which were counties in Hebei. Then go north to Boping, attack Qinghe Guoling County, turn to Beiqiu, and march to Ganling.

Su Lie didn't have many soldiers and horses, only 30,000, which was much less than Lejin. Lejin didn't want to defend when he had an advantage, so he decided to lead his troops into the field.

Le Jin has been famous for a long time, he was a general during the Cao Cao period, and now he has an army of 70,000, which is more than twice the strength of Su Lie, if he still defends the city, he can't swallow a breath at all.

He thought that even if the soldiers under Su Lie's command were elite, but he had twice the number of troops, he should not lose. He asked Wang Ling to defend the city, and Lu Qian to command the crossbowmen on the flanks. He led the elite to form a formation and rushed towards Su Lie's ranks, but he still underestimated the cavalry in Su Lie's hands.

Zhang Xiu is Zhang Yi's brother, and his relationship with Zhang Yi has been very good in recent years, and Zhang Xiu's son Zhang Quan even married Lu Su's daughter under Zhang Yi's matchmaker. Zhang Yi's family is basically gone because of the war in Liangzhou, only Zhang Xiu, a relatively close relative, naturally will not treat him badly.

The most elite Xuanjia army was not assigned to Zhang Xiu, but the cavalry under his command was all built by Zhang Yi in the early years, and now they have become heavy cavalry, far stronger than ordinary cavalry.

When Le Jin attacked Su Lie, Zhang Xiu directly led the heavy armored cavalry and directly attacked Lu Qian's troops on the flank. The heavy cavalry charged, unstoppable.

Lu Qian found that Zhang Xiu's cavalry was rushing and immediately let the front row of the car formation hold on. But their arrows were not very powerful against the heavy cavalry, and the heavy cavalry rushed over, threw out their hooks and pulled the car formation, and the heavy cavalry behind immediately rushed into the bow and crossbow array.

Lü Qian's crossbowmen were hit and immediately retreated. But how could they outrun the cavalry? Constant slaughter.

Le Jin also saw it and immediately divided his troops to save him. But he was fighting against Su Lie, and as soon as his side moved, Su Lie launched a fierce attack and dragged Le Jin.

Le Jin was entangled by Su Lie and could only send a partial general to support, but the supporting soldiers did not resist the impact of the heavy cavalry, and fled with Lu Qian.

Zhang Xiu pursued all the way to the city gate, and Lu Qian didn't even have time to enter the city, so he could only pass the city and retreat north.

Le Jin didn't last long, and after two hours, he couldn't resist Su Lie's fierce attack, so he could only retreat to the city. But Zhang Xiu had already intercepted under the city, just outside the range of the bow and arrow in the city, sprinting back and forth, stopping Lejin.

Later, he pursued the soldiers, and there was an interception in front, and Le Jin could only cross the city like Lu Qian and go to join Lu Qian.

After the convergence, Le Jin said to Lu Qian: "I was too arrogant before, what should I do now?" ”

Lu Qian is also an old man in the Cao Cao era, and he is both civil and military, and he can be a general or a shepherd. Lu Qian said: "Now that Ganling is no longer defensible, it is better to withdraw troops from Guangzong and guard the boundary bridge." The terrain of the boundary bridge is easy to defend and difficult to attack, in the past, Yuan Shao defeated Gongsun Zan at the boundary bridge, and we may be able to follow suit. ”

When Le Jin heard this, he nodded and said, "Just do it!" ”

So Le Jin asked Lu Qian to evacuate first, and according to the boundary bridge, he went to pick up Wang Ling. After Wang Ling received Lejin's retreat order in Ganling, he immediately set fire to the city and then retreated.

Su Lie could only enter the city first to extinguish the fire and let Wang Ling retreat.

Wang Ling was a member of the Taiyuan Wang family, and his nephew of Situ Wang Yun of the Eastern Han Dynasty, fled back to Taiyuan after Wang Yun was killed by Li Dao and Guo Yan, and was later appointed as the head of the Fa Cadre and dismissed from office for his crimes. Cao Cao happened to meet Wang Ling, who was serving a sentence, and when he heard about him, he exempted him from punishment and summoned him to the Prime Minister's Mansion to serve. Wang Ling is also a figure who is both civil and military, and he is very talented.

Su Lie entered the city to extinguish the fire, and did not extinguish the flames until midnight. Although many houses were burned in Ganling City, Su Lie still seized dozens of grains.

After occupying Ganling, Su Lie rested while letting Lü Guang capture the surrounding county seats. There are seven counties in the Qinghe country, out of Guangchuan in the north of the Qinghe, the remaining six counties are in the south of the Qinghe, Ganling, Beiqiu, and Lingxian have been captured by Su Lie, and Lü Guang attacks Juxian, Yimu, and Dongwu City to the east.

After resting for more than ten days, Su Lie marched to the boundary bridge. The boundary bridge is located several miles east of Gwangjong, on the Qing River. It is an important strategic place, because this bridge is one of the few bridges that can easily pass through grain trucks, and there is no need to cross the river by boat, so Yuan Shao and Gongsun Zhan will fight here, and it lasted for two years.

When he arrived at the boundary bridge, Lu Qian put out a strong bow on the other side of the boundary bridge, wanting to intercept Su Lie at the boundary bridge.

However, Su Lie smiled coldly, the river Qinghe was almost the same as the river, how could it be difficult for him? It's just a boundary bridge, and if it weren't for the convenience of transporting grain, he wouldn't have come here.
