After another half a month, Cao Cao's army withdrew from Xuzhou, leaving Cheng Yu and Xiahoudun to guard the rear, and personally led Xun Yu, Xiahou Yuan, Yu Ban, Li Dian, Cao Hong and other generals to rush over. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

At this time, the morale of the Cao army was the most victorious, and the soldiers in the army were all veterans of a hundred battles and had rich experience.

He came this time to take revenge, and secondly, he wanted to use Yuan Shao's momentum to get some oil and water.

Cao Cao knew that the one who mastered the Xiliang army this time was a little-known hairy boy with no experience, let alone any background, but he was very loved by the Xiliang sergeant.

However, he has never taken Xiliangjun in his eyes, in his impression, the prestige of Xiliangjun in the past is long gone, and now it has become a black sheep who only knows how to rob homes and houses, and everyone avoids it.

Therefore, he hopes that Yuan Shao can enter Chang'an, and then he can take advantage of the situation to recover Xiliang and pocket the prosperous place of Chang'an and Hanzhong, which will be beneficial to a certain hegemony in the future.

The two armies and one place, with Yuan Shao as the commander and Cao Cao as the deputy commander, began to fight the wheel of Hangu Pass.

For such a level, there is really no good strategy to use, except for using slingstones, ladders, and giant crossbows to reduce the enemy's strength and demoralize the enemy, there is really no way at all.

However, Cao Cao secretly hid a killer feature, holding a secret letter from Wang Yun in his hand, which recorded in detail the city defense and military strength of Chang'an, and promised to be willing to do internal response, and even listed the details of the plan clearly.

In this way, the two sides fought day and night for a month, Yuan Shao and Cao Cao's soldiers were more generals, each time they took turns, each unit could rest for three or five days, but the Xiliang army was not good here, even if the soldiers were not afraid of death, but they also had to sleep, the three armies took turns to defend the city, they were already sleepy and tired, and the materials for the city defense were almost consumed, and the next battle would be a white-knuckle battle, without too much skill, that is, pushing the ladder and cutting the enemy who rushed up.

Cao Cao calculated the days, if what Wang Yunxin said was true, then in the past two days, the Xiliang Army should have changed guards with the Baibo Army, and this is also the best time to take Hangu Pass by himself.

As expected, on the morning of the third day, the flag on the city wall changed color, this time an unknown old general, leading the Baibo army to defend the city, exactly like what Wang Yunxin said.

Cao Cao was secretly happy in his heart, but with his suspicious character, he refused to go in person, so he handed over Wang Yun's secret letter to Yuan Shao, saying that it was a secret report received in recent days.

Yuan Shao attacked the city repeatedly, but he had no success, and he was anxious, seeing that Cao Cao had revealed such important information to himself, he did not doubt it at all, and according to the above agreement, at noon, he counted the men and horses, and prepared to take over Hangu Pass.

At midnight, the city gate of Hangu Pass was opened, and the flames on the city were lit up and extinguished, as if to send a signal to the city.

Yuan Shao sent Zhang He as the vanguard, led 5,000 men and horses to cross the Hangu Pass, left 20,000 infantry as backup, and personally led the army through the Hangu Pass.

Even though the troops of nearly 80,000 troops of the two armies passed through the Hangu Pass, Cao Cao was still not worried that the Baibo army would defend the pass alone, so he sent Xiahou Yuan with 2,000 crossbowmen to assist in defending the city, and transferred most of the surrendered Baibo army and stationed them in the south of Chang'an City, the purpose of which was to prevent these people from rebelling again.

The Cao Yuan coalition army was overwhelmed all the way, and although it encountered sporadic resistance, it was quickly suppressed, and it reached the city of Chang'an in less than two days.

The flag on the city is unfurled, with a big Lu character written on it, and a big man who is half a body taller than the soldier is standing on the city tower, it should be Lu Bu, it seems that this is Zhang Yuntian's last bargaining chip!

Cao Cao knew that Lü Bu was brave and good at fighting, so he consulted with Yuan Shao and sent troops to surround the north, east and south gates of Chang'an City, leaving only the west gate.

The purpose is to scare Zhang Yuntian away, and then send troops to set up an ambush on the road, as long as Zhang Yuntian is captured, Xiliang will definitely change hands again, and this time, it is likely that it will be his turn.

Yuan Shao didn't think so far-reaching, after all, Xiliang was too far away from Jizhou, and Gongsun Zan behind him hadn't finished fighting, and there was Zhang Yan's Black Mountain Army between the two places, and it was a taboo for soldiers to be cut off, so he didn't want to stay long at all, and was ready to capture Chang'an, loot it on a large scale, and then take Emperor Xian back to Yecheng, with Dong Zhuo and Zhang Yuntian in front of him to demonstrate, he also understood the benefits of having the Son of Heaven.

It's just that his reputation is outside, if he welcomes the Son of Heaven, he will inevitably let the world return to his heart, and this road to unification will be much easier.

The two armies were around Chang'an City for more than a month, although Chang'an City was not as easy to defend as Hangu Pass, but the city was rich in materials and had many troops, so this battle was not much easier than Hangu Pass.

Yan Liang rushed to the city with the death squad several times, but was finally blocked by Gao Shun and Zhang Liao.

After a few days, I suddenly reported that there were a large number of displaced people at the west gate of Chang'an, and they walked to the boundary of Xiliang under the escort of the Xiliang army, and there was a dragon in the team to offer the emperor.

Cao Cao was of course overjoyed when he received the news, and he discussed it with Yuan Shao.

Wen Chou led the troops to intercept and kill, Li Dian ambushed at the necessary place to Xiliang, and two soldiers and one captured Zhang Yuntian.

Because Lu Bu and Gao Shun are all in Chang'an City, there must be a lack of guards around Zhang Yuntian, and this blow can be described as foolproof.

As long as this side succeeds, Chang'an City will almost be self-defeating.

However, Wang Yun seemed to be very uneasy about Cao Cao, and sent someone to secretly send a secret letter, saying that he was willing to do internal response, and at the third watch, he led the family to open the south gate and welcome the coalition army into the city.

With the first experience, Cao Cao was of course reluctant to share this important matter with Yuan Shao, after all, this time it was Chang'an City, and whoever settled in first would have more control over wealth and a more famous reputation.

So he secretly ordered 10,000 horses, and took Cao Ren, Cao Hong, and Xu Huang to prepare to sneak into Chang'an City, and let Yu Banqin lead the remaining troops to feint at the east gate.

All this is too smooth and too unsmooth, what is not smooth is that Hangu Pass has been fought for so long, and Chang'an City has lost a lot of soldiers, and the smooth thing is that Wang Yun has made internal responses every time, it seems that when this battle is over, Wang Yun must be given a great credit.

At the time of the third watch, the east gate and the north gate were still killing the sky, the two sides fought to the death, but the south gate was quiet, not long after, a burst of blades intersected sounded, and the suspension bridge of the city gate was put down.

Cao Cao shouted and rushed in with a large army, so frightened that the soldiers defending the city fled one after another. (To be continued.) )
