Liu Bei can be regarded as seeing the form clearly in his heart, if Zhu Wei really controls Pengcheng, he will inevitably seek to seize the entire territory of Xuzhou.

Now that the Xiaopei he occupies is so close to Pengcheng in Xuzhou, he will definitely not be let go easily by Zhu Wei, and I am afraid that he will not be allowed to live in Xiaopei safely at that time.

At the same time, Liu Bei was not willing to be sandwiched between the two major forces of Zhu Wei and Cao Cao to make sandwich cakes, so he "ate jujube pills", no matter which side sent troops, if he refused to surrender, he would be the first target to be eliminated.

Of course, Liu Bei is not willing to surrender to Zhu Wei and Cao Cao easily, then he will never come out, so if Zhu Wei's army comes, his Xiaopei will definitely not be able to resist, and it is impossible for Cao Cao to send troops to rescue him.

It's better to play now, if you can't do it, you can run away again.

At this moment, Liu Bei is also deliberately alarmist to Zang Ba, just to pull Zang Ba to join Yuan Shao, anyway, now that Zang Ba is already attached to his name, then it is best for him to be able to gain a foothold in the land of Mount Tai, Langxie, and Beihai in the north of Xuzhou with the support of Yuan Shao.

Then Liu Bei will still have the opportunity to peek into Xuzhou, and with the support of Yuan Shao, he can use the reputation and connections he left in Xuzhou in the past to seek opportunities to obtain Xuzhou.

Zang Ba also thought about it when he heard this, and felt that he might indeed want to try the combat effectiveness of Zhu Wei's army, if Zhu Wei's army was really as strong as the legend, then he could find a way to surrender to Cheng, as long as he could keep his territory in Taishan County.

"Okay, Xuande Gong, this time a certain is taking a risk, and Xuande Gong can't live up to a certain in the future!"

Zang Ba actually guessed a little bit of Liu Bei's thoughts in his heart, but he wouldn't show it at the moment, anyway, he still has Taishan County, a nest that has been entrenched for many years, and the big deal is to flee back to the mountains as a thief.

Liu Bei and Zang Ba reached an agreement again, just to prevent Zhang Liao from attacking again, after spending a night in the open air in the ruins of this camp, the two simply abandoned the camp here with the army, moved all the materials with the army, and came directly to the north gate of Pengcheng to station.

Later, Liu Bei and Zang Ba actually stopped the army at the original camp of Zhang Liao, although this side has been burned to the point where only a black place remains, but it is also a good place to camp.

Therefore, Liu Bei and Zang Ba spread their nearly 30,000 troops here, protected their remaining grain, grass and supplies, and then began to send troops to fill the moat of Pengcheng and launch an attack on Pengcheng.

Although in Zhang Liao's previous attack on the camp, Liu Bei and Zang Ba's camps were burned down a lot of things, but now Liu Bei still uses the remaining carriages and other vehicles to transform them into some simple siege cave houses.

In this way, Liu Bei could send troops to safely fill the moat outside the north gate of Pengcheng, which was the siege tactic that Liu Bei learned from Zhu Weijun.

Then Liu Bei also used the protection of the cave house car to dig up the city wall of Pengcheng closely, urging his auxiliary soldiers and young men to dig the city wall almost day and night, and the efficiency was not very slow.

Although Lu Lingqi, who guarded Pengcheng, led the troops to launch some defensive counterattacks, but with the protection of Liu Bei and Zang Ba's soldiers, as long as Lu Lingqi did not dare to go out of the city to engage in the battle, then the defense on the city wall was really nothing to do for the soldiers hiding in the cave house.

After that, when these cave houses filled the moat and were close to the city wall, the falling rocks, rolling wood, and fire oil on the city wall could also pose some threats to the cave house cars, but Liu Bei made up his mind to dig the city, so at the beginning, he didn't care about the consumption of the cave house cars, but just sent them to the wall and kept digging holes, and finally dug a cave at the bottom of the city wall that could accommodate people.

In this way, Liu Bei's auxiliary soldiers and young men hid inside and dug inside, which made the defenders on the city wall helpless.

Lu Lingqi knew that after Liu Bei and Zang Ba's army dug the city, they could only build a new wall urn city in the city, lest Liu Bei and Zang Ba's army dig through the city wall, and they could directly enter Pengcheng.

So the war was stalemate, waiting for the results of the excavation of the combined forces of Liu Bei and Zang Ba.

However, Liu Bei and Zang Ba's city-digging tactics do take a lot of time, so Lu Lingqi is not too worried, and when Zhu Wei's reinforcements come, he will naturally not be afraid of Liu Bei and Zang Ba's army.

And in this process, Zhang Liao also led his troops to join Song Xian's soldiers and horses, and secretly observed the movements of Liu Bei and Zang Ba's army, looking for an opportunity to raid.

However, at this time, Liu Bei and Zang Ba's army gathered together, although there was no protection of the camp, but they also strictly arranged the tour scouts around.

If this Zhang Liao wanted to lead troops to sneak attack, he would be detected by Liu Bei and Zang Ba far away, so that he would be prepared to face the battle, but the troops controlled by Zhang Liao did not dare to really compete with the more than 20,000 main forces controlled by Liu Bei and Zang Ba.

Therefore, Zhang Liao could only continue to spy around, but he never found any opportunity to sneak attack again.

Three days passed quickly, and the soldiers and horses of Xu Shu who set off from Guangling finally came to the territory of Pengcheng, and Zhang Liao led the troops to join Xu Shu's army in the periphery of Pengcheng.

However, Xu Shu brought more than 4,000 soldiers and horses, even if he joined forces with Zhang Liao's army, it would not pose much threat to Liu Bei and Zang Ba's army.

When Xu Shu understood the battle situation in Pengcheng, he did not have the intention of uniting Zhang Liao's army to attack Liu Bei and Zang Ba's coalition army, anyway, Liu Bei and Zang Ba are still digging the city wall of Pengcheng, and there will not be many changes for a while.

Xu Shu had already learned through the military newspaper that Zhu Wei had sent the main force of Tai Shi Ci's Divine Arrow Battalion to Pengcheng, so Xu Shu only continued to be stationed in the outer area of Pengcheng with Zhang Liao, waiting for the arrival of Tai Shi Ci's main force.

The current war situation cannot be solved by any strategy, and can only rely on the hard confrontation of the armies of both sides.

Now the combined forces of Liu Bei and Zang Ba are stronger than the combined forces of Zhang Liao and Xu Shu in terms of strength and combat effectiveness of the army.

Once the war is unfavorable, it will increase the morale of Liu Bei and Zang Ba's coalition army.

Therefore, even if Zhang Liao and Xu Shu want to attack, they must choose the right time, such as when Liu Bei and Zang Ba launch an attack on Pengcheng, so that they can flank the combined forces of Liu Bei and Zang Ba, and maybe have some chance of winning.

After another two days, the excavation of Pengcheng by the combined forces of Liu Bei and Zang Ba in front of him seemed to have some effect, and it actually dug up part of the north wall of Pengcheng.

In fact, this is an accident caused by the auxiliary soldiers and Qingzhuang driven by Liu Bei and Zang Ba who don't know any excavation techniques, but just cover their heads and wet the rammed earth city wall with water and dig the passage.

These auxiliary soldiers and young men brought by Liu Bei and Zang Ba dug the city wall with hoes and shovels, although they dug up a passage that was more than one person high and three people wide on the rammed earth city wall, but they did not take any reinforcement measures for the passage.

Therefore, as the passage deepened, the entire passage collapsed, but it also caused the collapse of the city wall, and a breach appeared......
