An Cheng soldiers laughed. Su Yunchu's newborn calf and five thousand soldiers and horses didn't even scratch. Murong yuan is entangled with the soldiers on the east bank. They just need to keep an city well.

However, just when the soldiers of an City disdained to pay attention to the young Su Yunchu even at night, Su Yunchu took a group of elite soldiers and directly bypassed an city. He put all his horses in the front of an City, led the soldiers to use the terrain to bypass the front of an City, and attacked an City in the north before dawn.

An Cheng was caught off guard and fell.

In any case, the generals of Ancheng can't imagine why Daxin can bypass the front and directly attack the north of Ancheng, because under reasonable and normal circumstances, Ancheng is a special existence along the porphyrin River, surrounded on three sides. Only when the east bank falls, Ancheng will directly respond to the enemy, but now

However, no one knows that Su Yunchu likes to be surprised. She has studied the terrain and data around the porphyrin river. Since then, when she sneaked into an City, she found a dangerous place behind an city that is not easy to be detected. Because it is a dangerous place, the guard is not strict. It is by virtue of the terrain advantage that she opened the gap into an city.

In this battle, no one will ever understand that the fall of this important military town is due to a woman's strict requirements for terrain.

On the day when Su Yunchu captured Ancheng, Murong yuan attacked the east bank again. The Beiliang soldiers were excited about the fourth defeat of Daxin. The myth of Murong yuan's invincibility was about to disappear from their hands. It was the original general who had doubts about Murong yuan's obvious inability in recent days. However, seeing this opportunity, Without thinking, he ordered a fierce chase and never stopped.

The Daxin soldiers did not live up to their expectations and led a group of chasing Beiliang soldiers into the ambush circle that had already ambushed tens of thousands of Daxin soldiers. By the time Beiliang found something different, it was already late.

In this way, all the pursuers were destroyed.

Jia Cangfeng and the porphyrin River fell one after another, and even an city was destroyed. Jie City was in danger. After the fall of the two places, Gan Ji did not retreat to Jie City, but directly took the remaining soldiers and horses, left the three defense lines, retreated back and retreated to the next town. In this way, his hatred for Murong yuan rose again.

Murong yuan let him run away. Unexpectedly, today, Murong yuan still let him run away.

Gan Cheng, who is far away in Xiyuan, naturally heard the news, but what can he do? Xiyuan is also a formal crisis. Xiyuan's internal crisis has been solved, and the crown prince's rights have been successfully consolidated. Then, he will make every effort to carry out an offensive to meet the attack of Beiliang.

Empress Dowager Gan heard the news naturally in the palace. Gan Ji once vowed that he would guard the three lines of defense. These three lines of defense are a lifeline of Beiliang. If anything goes wrong, she told him that she was relieved to let Gan Ji go because she felt that the three lines of defense were very strong. Now, he has destroyed the three lines of defense.

As for the finishing work of the three lines of defense, it was more smooth in the later stage. Murong yuan took the East Bank of the porphyrin River, Su Yunchu took the an City, and Jie City, the second day after the attack of the porphyrin River, followed the same pattern. The Daxin army that had earlier circled behind Jie City also caused a fatal attack on Jie City.

Beiliang fell twice in the same place, and his morale was lower.

Yan Yishan on the other side, of course, has cut off the reinforcements from the towns near Beiliang according to the previous deployment.

To Yan Yishan's surprise, in addition to cutting off Beiliang's reinforcements in front of her, Su Yunchu took over the city of an after she captured it. However, she took two thousand blue eagles and three thousand light soldiers from the flank and went around to the back of Beiliang's reinforcements in the area of Chu mountain, The Beiliang reinforcements returned after being intercepted by Yan Yishan were blocked in the valley mouth of Chu mountain. The Beiliang reinforcements could not advance or retreat, and another round of reinforcements could not continue to arrive. There was Yan Yishan in front and blue eagle in the back. Under the command of Su Yunchu, a stone battle in the valley killed and injured more than 90% of the returned Beiliang reinforcements.
