As soon as Chen Cang is facing the water, it is dangerous on three sides, such a terrain is destined to besiege Chen Cang cannot be like an iron bucket, in fact, the siege of the Shu army is indeed relatively loose, and many gaps are more like intentionally or unintentionally left, which makes Su Yu's breakthrough very easy.

Su Yu chose the breakthrough point in the northeast direction of Chencang, this position Su Yu observed in advance, and found that this was the junction of the Yang'an Camp and the Yong'an Battalion of the Shu Army, and the connection between the two battalions before looked loose, and a large gap appeared.

Unlike the upright and courageous Wang Hun, Su Yu is the kind of person who is smart and smart, and he is more on top of Mingzhe's self-protection, the failure of the battle of Wuzhangyuan made Su Yu feel that Chen Cang could not be defended, since he couldn't hold it, then staying in Chen Cang any longer would be a senseless sacrifice, and only by taking advantage of the fact that the Shu army had not yet formed a siege of Chen Cang and seized the opportunity to escape. Su Yu didn't even bother to pay attention to the stubborn Wang Hun, he was simply stupid. Now there is no point in defending Chencang, after the victory of the Shu army in Wuzhangyuan, the spearhead of the attack will naturally point to Chang'an, and the gains and losses of Chang'an will ultimately determine whether the Wei army can survive in Guanzhong.

In order to judge the situation and change the situation at the right time, Su Yu does not think that he is escaping from the battle, and the evacuation of Chen Cang is to preserve the strength of the Wei army, and to contribute to the next step of guarding Chang'an, Wang Hun is a martial artist, how can he think so thoroughly, it is simply playing the piano to the cow.

Anyway, he is also benevolent and righteous, Wang Hun is unwilling to go, so he has to go with him.

When Su Yu left the gate of Chencang, he suddenly felt infinite emotion in his heart, how full of ambition he was when he led his troops into Chencang, Chencang should have been the place where he became famous, but the world was unpredictable, only a few days later. Su Yu had to leave Chen Cang gloomily, the glory he had expected did not appear, and the results he originally longed for were also bleak, all of which were very different from what he imagined.

Liu Yin is really a terrible opponent! Su Yu sighed secretly in his heart, if Liu Yin adopted the same style of play as Zhuge Liang back then. Concentrate the army to attack Chen Cang, then Chen Cang will definitely become a stage for him Su Yu to play his strengths, relying on the seven thousand elite soldiers he brought and Chen Cang's rock-solid defense, Liu Yin will also be trapped under Chen Cang City and cannot advance an inch, and when Sima Wang's reinforcements come, there will be another inside and outside, everything will be perfect.

It's a pity that Liu Yin doesn't play cards according to common sense, and the siege of Chen Cang is only a partial division, while the real main force is waiting in Wuzhangyuan. The battle of Wuzhangyuan not only defeated Sima Wang's reinforcements, but also completely changed the overall situation of the Guanlong area, and also shattered the confidence of the Wei army in sticking to Guanzhong.

Su Yu is also familiar with military books, and he is also familiar with strategies such as attacking the east and west, and encircling Wei to save Zhao, but the strategies adopted by Liu Yin seem to be fundamentally different from these. The core of Shengdong attacking the west is the west, and the core of encircling Wei to save Zhao is Zhao. But Liu Yin's purpose was not in Chencang, his appetite was not just a small Chencang City, but was aimed at the main force of the Wei army that came to the rescue. Siege and reinforcement, siege is only a means, and reinforcement is the real goal.

Thinking of this, Su Yu couldn't help but shudder. Liu Yin's courage and resourcefulness are unmatched even by the soldiers of all dynasties, and such an opponent is a truly terrifying opponent.

Su Yu didn't want to stay in Chen Cang at this moment, God knows what more terrifying means Liu Yin has in the future, and the fall of Chen Cang is only a matter of time. Only by successfully breaking through can there be any hope of survival.

The Shu army outside the city seemed to be unprepared for the sudden breakthrough battle launched by the Wei army, and the time Su Yu chose to break through was four watch in the morning, and the location chosen was the gap between the two battalions of the Shu army, so after the operation began, it went very smoothly and soon broke through the first line of defense of the Shu army.

When Fu Tong received the report, the entire northeast defense line of the Shu army was full of murderous sounds, and the messengers looked panicked, and reported to Fu Tong without stopping their breath. However, Fu Yan was calm, although the breakthrough of the Wei army was a relatively unexpected thing, but whether it was a full or partial breakthrough of the Wei army, it was good news for the besieging Shu army, which proved that cracks had appeared in the ironclad Chencang City, and the capture of Chencang was just around the corner.

"The herald Yang'an Camp and the Yong'an Battalion don't have to desperately block the Wei army that broke through, you can consider giving them a way out, but this road can't let them pass easily, at least let them pay a price. At the same time, block the road in the direction of Chen Cangcheng, and don't let them turn back! Fu Yi ordered. Since the Wei army defending the city had the intention to break through, it would be a fulfillment for them, as long as they did not retreat to Chencang, there would be no place for them to escape there.

Under the cover of night, Su Yu's breakthrough plan went very smoothly, and the 7,000 Wei army, with cavalry as the lead and the left and right flanks as infantry, launched a rapid offensive against the defense line of the Shu army. On the fourth watch, it was the time when people were sleepy, although the Shu army camp sent a large number of patrol sentinels, but most of the soldiers experienced a day of fierce fighting, exhausted, and were asleep at the moment, the sudden attack of the Wei soldiers naturally woke up the good dream of the Shu army, and the horn of the warning also sounded poignantly, echoing in the night sky, the drumbeat of the assembly drove away the fatigue of the Shu army, and the Shu army crawled out of the camp tent one after another, and quickly completed the assembly to resist the attack of the Wei soldiers.

But no matter how well-trained a soldier is, it is impossible to complete the assembly in a single pillar of incense, and no matter how well-trained a soldier is, it is impossible not to produce a certain degree of chaos, Su Yu took advantage of the chaos of the Shu army and rushed over in one go.

However, the deeper the Shu army position, the greater the resistance, and as time went on, more and more Shu troops began to gather in this direction, even though the Wei army's breakthrough action brought many obstacles.

Such a situation had long been in Su Yu's expectations, but Su Yu's determination to break through was extremely resolute, and he forcibly ordered the Wei army's attacking arrow troops to speed up their march, and at all costs, to fight their way through the chaos.

In the dark melee, Su Yu didn't know how many people his army had lost, he had come to this point, he had no way to retreat, only by fighting desperately, he had a chance to break out of the encirclement.

When the sky was slightly dawning, the vanguard of the Wei army had already arrived at the periphery of Chen Cang, and the pursuers behind were getting farther and farther away, and Su Yu secretly breathed a sigh of relief. (To be continued.) )
