"Come on, prepare rockets, burn them!"

Zhang Liao looked at the grain and grass and warehouse area guarded by Mi Zhu and Wu Dun in front, as long as he sent the archers to the forefront, they were all within the range of the bow and arrow.

Anyway, the obstacles posed by those cars, although they prevented his people from approaching, also made Liu Bei and Zang Ba's army unable to kill and hurt the archers, so Zhang Liao didn't want to break through, but was just ready to set fire to the grain and grass inside, which could also achieve his strategic goal.

"No! Promise! ”

Several military marquis agreed to the order, and immediately went to arrange archers, and after a while, feather arrows with fire jumped over Liu Bei and Zang Ba's soldiers who were defending in the inner center, and shot towards the storage area in the rear.

Soon a rocket landed on a granary, but it was extinguished by the yellow mud smeared on the periphery, but one rocket after another pierced up, and finally ignited the grass and trees inside, as well as the stored corn and grain.

"It's water, it's water!"

When Liu Bei and Zang Ba's soldiers in the middle saw the fire, some auxiliary soldiers and young men couldn't help but exclaim in their mouths, and Mi Zhu and Wu Dun also understood Zhang Liao's intentions, but at this moment, there was no way to counteract, so they could only divide some people to extinguish the fire.

Seeing this, Zhang Liao's heart moved, and he looked around a few more times, and quickly ordered his soldiers to pick up some tents and so on that were on fire, and put them upwind with bamboo poles, etc., and suddenly some cloth with sparks floated to the storage area over there with the wind.

This kind of ignition effect can cover a wider range than that of a rocket.

Even if the storage area here is specially separated from the distance between the grain and grass piles and the material piles in order to prevent fire, which can prevent the flames from spreading rapidly inside, but now under Zhang Liao's arrangement, a large number of sparks and cloth have drifted in with the wind, not to mention blocking, it is not easy to find the location where they fall.

However, as long as they can ignite the dry grass and food, they will naturally cause fireworks, so it didn't take long for smoke to rise in many places in the storage area, and fires were ignited in many places.

Seeing this, Zhang Liao couldn't help but laugh proudly, and at this time, a scout suddenly rode to report that there were soldiers and horses in the direction of Pengcheng.

"Withdraw your troops!"

Zhang Liao looked at the storage area where there were more and more smoke and fires, and no longer hesitated, and directly beckoned his subordinates to evacuate, although it was not yet completely burned Liu Bei and Zang Ba's grain and grass, but at least part of it could be burned.

Anyway, this time he also destroyed this camp, and then he still has a chance to come again, and then it will be up to Liu Bei and Zang Ba to dare to attack Pengcheng with the whole army.

As long as Liu Bei and Zang Ba were afraid, their strength in attacking Pengcheng would naturally be weakened.

So Zhang Liao led his troops quickly through the burning camp area, and withdrew northwest along the Surabaya River, this time Zhang Liao was going to find a place to cross the Surabaya River and join Song Xian's soldiers and horses, so that he could have more soldiers and horses to fight in the periphery.

As a result, Zhang Liao withdrew in a very timely manner, and when Guan Yu came back with his troops, he basically only saw the ruin-like camp here.

Now the original more than 10,000 auxiliary soldiers and young Zhuang have fled four or five percent, plus the troops retained in the hands of Mi Zhu and Wu Dun, there are less than 6,000 remnants left.

Even in the grain and grass storage area that was taken care of by Mi Zhu and Wu Dun, there were many fires in many places, even if Mi Zhu and Wu Dun put out the fire in time, the stored grain and grass were still burned more than forty percent, which can be regarded as a great loss.

Guan Yu knew from Mi Zhu and Wu Dun that Zhang Liao had been gone for some time, and knew that he had no way to catch up, so he had no choice but to stay to extinguish the flames burning in the camp and clean up the mess.

Not long after, Liu Bei and Zang Ba also came back with a large army, but knowing the situation here, they also reluctantly accepted the current situation.

Of course, tonight, the soldiers of Liu Bei and Zang Ba's coalition army can only sleep in the open air, and even if they want to rebuild the camp, they may not be able to find enough trees and materials.

Fortunately, a lot of grain was still preserved by Mi Zhu and Wu Dun, and they would not be hungry, otherwise the army's spirit would be completely dispersed.

However, that night, Liu Bei and Zang Ba could only hold a meeting to discuss the current situation, obviously Zang Ba really had no intention of staying and fighting again, but Liu Bei was still a little unwilling.

"Xuande Gong, if it's not Zang Ba's cowardice, this really can't fight anymore! Now even the camp can't be built, if our army attacks Pengcheng again, then Zhang Liao comes to sneak attack again, then how to resist! This time I have lost a lot of grain and grass, if Zhang Liao sneaks up on the grain and grass next time, then my army may not even be able to return to Mount Tai! ”

Now that the tents have been burned down, now Liu Bei and Zang Ba can only find rocks by the Surabaya River and sit on them.

Zang Ba can be regarded as admitting it, and now that Zhu Wei's reinforcements have not arrived, the war will be like this, so if Zhu Wei's reinforcements arrive later, won't they even have a chance to retreat.

What's more, judging from the current battle situation, they may not be able to capture Pengcheng, and now even the ladder frame needed for the siege has been destroyed, and it is difficult to find bamboo and wood to build a new ladder around them, so how can they attack the city.

"Xuan Gao, it is precisely because of the war that we can't retreat! If we can't attack Pengcheng, not to mention the vain loss this time, we will negotiate with Na Zhu Wei in the future, and we will be underestimated! ”

Liu Bei was still unwilling to persuade, this time the loss was so big, if he couldn't get anything in Pengcheng, his side would also lose a lot.

"But Xuande Gong, now we don't even have the equipment to attack the city, do you want your subordinates to climb the city with a ladder?"

Seeing that Liu Bei still said this, Zang Ba mocked with an ugly face, the wall of Pengcheng is five or six stories high, and it is naturally impossible to climb it up by human ladders, and it is really a decoration to be a guard of Pengcheng.

This method can only be used when attacking ordinary dock forts and small county towns, and if it is used in Pengcheng, it will be in vain to send them to death.

Liu Bei also frowned and thought about it when he heard this, this is a tricky question, and suddenly he seemed to think of something, and said to Zang Zang, "Xuan Gao is not in a hurry, I was prepared to participate in the battle of Shouchun, but when I saw that Zhu Wei attacked Shouchun City, he used the technique of digging the city, and now since we can't climb the city and attack, we can also dig through Pengcheng and enter!" ”

"Digging the city? Wouldn't it take a lot of time, but what if Zhu Wei's reinforcements came? ”

Zang Ba didn't expect Liu Bei to say such a siege method, and it was feasible to think about it, but it would take time.

"Even if Zhu Wei's reinforcements come, it won't be the main force, now Zhu Wei has just won Shouchun, and he has no time to look around, and the strength of our coalition army is not weak, even if there are Zhu Wei's reinforcements, it's just a fight! Xuangao, this battle is unavoidable, it's just that it will be fought in Pengcheng, or in Taishan in the future! ”

Liu Bei saw that Zang Ba was still worried about Zhu Wei's army, but he also said coldly, now Liu Bei has made up his mind in his heart, if he can't capture Pengcheng this time, then he will simply abandon Xiaopei and go north to join Yuan Shao......
