It can be said that before Tai Shici's Divine Arrow Battalion soldiers officially attacked, Zhu Weijun's various war equipment had already destroyed all kinds of defensive means arranged in front of Yuan's camp.

At the same time, Huang Zhongjun, who was in the rear of Yuan's camp, also launched a sneak attack on Yuan's army, and an army pretending to be a Zang Ba's army grain transport team slowly advanced towards the rear of Yuan's camp.

Now there are still 15,000 or 6,000 troops and nearly 10,000 logistics civilian service under Yuan Tan's account, plus nearly 3,000 or 4,000 people brought by Liu Beijun after he was attached to Yuan Tan's account, so that the scale of the entire Yuan army camp is at least the size of a town.

Therefore, when the front of the Yuan army camp was attacked by Zhu Wei led by Tai Shici, the rear of the army was still quiet.

As a result, at this time, a grain transport army under the banner of Zang Ba seemed to be moving slowly from the direction of Fenggao in the back of Zang Ba's back belly in the north, and slowly marched towards the rear village of the Yuan army, but it also attracted the attention of the officers and soldiers of the back village of the Yuan army.

However, when a large army fights, grain and grass are naturally indispensable.

The daily consumption of grain by tens of thousands of troops on the front line is also astronomical, and Zang Ba did not store too much grain and grass in Liangfu County, so naturally there was not enough grain to meet the needs of the combined forces of Yuan Tan, Zang Ba, and Liu Bei.

In this way, it is normal to transport grain and grass to the front line from the hinterland of Taishan County, which is controlled by Zang Ba in the rear.

Some of these grains and grasses were Zang Ba's own, but more of them were transferred by Yuan Tan from Qingzhou, just to facilitate transportation, the grain and grass from Qingzhou were first sent to Fenggao County of Zang Ba, and then Zang Bajun was responsible for receiving them, and then continued to be transported to Liangfu County.

On the surface, the Zang Ba army grain transport team that came to the back camp of the Yuan army camp seems to be no different from the grain transport team on weekdays, to say that the number of people seems to be more, at least four or five thousand, but the grain trucks they pushed are also much more than in the past.

Although the officers and soldiers of Yuan stationed in the back camp of the Yuan army camp were concerned, they did not have too many suspicions, and after the grain transport team approached, they just sent someone to check the order, and felt that there was no problem, so they directly opened the gate of the back camp and prepared to let the grain team in.

(In fact, under the planning of Xu Shu and Lu Su, Huang Zhongjun directly robbed a grain transportation team of Zang Bajun, thus replacing the original Zang Bajun with Zhu Weijun and then coming to Liangfu County, naturally there will be no flaws.) ）

And after the grain transport team entered most of the gate from the gate of Yuan Jun's rear camp, suddenly a grain truck broke the axle at the gate, and suddenly overturned and blocked the gate.

Immediately, as if they had received an order, these "Zang Bajun" transporting grain directly gave up their disguises, and rushed to kill in all directions in the rear camp of the Yuan army, and soon killed the defenseless defenders of the rear camp of the Yuan army, causing a great chaos in the rear camp of the Yuan army.

At this time, about one or two miles away from the rear camp of the Yuan army, Huang Zhong took the lead and took the elite of the Huainan battalion to the rear camp of the Yuan army to kill him.

The Huainan battalion brought by Huang Zhong also had more than 20,000 troops, and the number was enough to fight against Yuan Tan's army alone, not to mention that Yuan Tan's main energy was now focused on facing Tai Shici's side in front, so Huang Zhong led his troops to suddenly enter Yuan's army camp, which was like a sharp blade stabbing into a chrysanthemum, and he did not encounter any enemy who resisted at all.

After Huang Zhong led the 20,000 troops of the Huainan battalion into the Yuan army's camp, he quickly captured most of the area, causing a great chaos in the rear of the Yuan army.

And with the chaos in the rear of the Yuan army, the Yuan Tan army on the frontal battlefield naturally followed the chaos, Yuan Tan didn't know what was happening behind, but he just sent part of his troops back to resist Huang Zhong's army, but how could it play any role.

At the same time, Tai Shici, who was attacking head-on, discovered the fireworks burning in Yuan's camp, and knew that Huang Zhong must have led his troops to kill, so he also launched a frontal attack.

In this way, Tai Shi Ci's Divine Arrow Battalion soldiers also entered the Yuan army's camp from the front, and with the help of various war equipment to destroy the Yuan army's frontal defense methods, Tai Shi Ci's Divine Arrow Battalion soldiers did not encounter any obstacles in the past.

As a result, under the front and rear attacks of Zhu Weijun, Yuan Tanjun's army was completely chaotic.

Among them, Liu Bei was the smartest, and he found out that the situation was wrong at the first time, so he took Guan Yu, Zhang Fei and a group of subordinates and fled directly to the gate of Liangfu County, and then fled into the county seat.

But Yuan Tan was originally in front of the command of the battle against Tai Shici, and after he found out that the situation was not good, it was too late to escape.

And Tai Shici specifically targeted Yuan Tan, so he naturally sent people to chase Yuan Tan closely, so that when Yuan Tan fled to Liangfu County, Zang Ba didn't dare to open the city gate to receive Yuan Tan into the city, and when the time came, he was afraid that Zhu Weijun would also be able to take advantage of the situation to follow into the city.

Zang Ba had no choice but to guide Yuan Tan to retreat to the Culai Mountain in the north of Liangfu County, and at the same time, he also sent some men who were familiar with the mountain road to hang them from the city wall to the outside of the city to lead Yuan Tan in the mountains.

Yuan Tan naturally had no power to accuse Zang Ba of anything at this time, so he had no choice but to flee to the mountains according to Zang Ba's wishes.

But in the end, after he successfully crossed the Culai Mountain, there were less than 2,000 soldiers around him, and it can be said that the Qingzhou Yuan Tan army, which originally had at least 15,000 or 6,000 troops, died no less than 3,000 people under the attack of Zhu Weijun, and most of the remaining more than 10,000 people also became prisoners of Zhu Weijun.

However, Yuan Tan experienced this defeat, where did he dare to stay in Taishan County, so he withdrew to Qingzhou with the remnants of the army, and there was nothing to care about for the time being.

As for the side of Liangfu County, with the convergence of the Shenjian Battalion and the Huainan Battalion led by Tai Shici and Huang Zhong, Zhu Weijun surrounded Liangfu County to death with at least nearly 50,000 troops.

In Liangfu County, there were less than 8,000 Zang Ba's army, and Liu Bei's army who fled into the county seat was only 1 or 2,000 people.

At the same time, this Liangfu County is not a big county in Gaocheng, and there are not many grain and grass reserves in the city, so after Zang Ba and Liu Bei were besieged, they naturally fell into a desperate situation.

However, after Tai Shici and Huang Zhong led their troops to surround Liangfu County, they persuaded Zang Ba in the city to surrender.

Under the analysis of Xu Shu and Lu Su, Zang Ba actually has no need to carry it to the end in the city, and there is still the possibility of persuasion to surrender, and Zhu Weijun should not continue to delay too much time in Taishan County now, if Zang Ba is willing to surrender, it is the best result to quickly solve the war on the side of Taishan County.

Xu Shu and Lu Su have now realized the changes in the situation today, and they know very well that Zhu Wei needs the forces on their side to be deployed and used as soon as possible.

So according to the opinions of Xu Shu and Lu Su, Zhu Weijun proposed two conditions for surrender to Zang Ba, and gave Zang Ba a day to consider, if Zang Ba could not give an answer in time, then Zhu Weijun could only attack Liangfu County......
