Of course, Zhu Wei couldn't feel that Puyang City was difficult to gnaw down, so he gave up withdrawing his troops.

Although when Zhu Wei came to the city wall of Puyang City and looked at the various block fortresses still occupied by Cao Jun in Puyang City and the inner city of Puyang at the core, he was also surprised by the defense of the city constructed by Cao Cao, but Zhu Wei would never give Cao Cao a chance to spare his life.

So after looking at the situation in Puyang City, Zhu Wei made a ruthless decision to set fire to the city.

Since Cao Cao made such a scene in Puyang City, Zhu Wei didn't want his army to fight inch by inch, and then consume a lot of troops in the senseless siege street battle.

Anyway, the houses and buildings in Puyang City are still mainly made of wood, so let's burn them all.

Even if Cao Cao gathered at least 60,000 or 70,000 people in Puyang City now, if he really set fire, he could easily burn so many people to death in the city, but because Cao Cao still had so many troops gathered in Puyang City, Zhu Wei could only use arson to eliminate them at the lowest cost.

Of course, Zhu Wei, as the lord, naturally couldn't speak out about this plan in person, so after Zhu Wei's army completely captured the outer city walls of Puyang City, opened up various city gates, occupied the urn city within the four gates, and cleaned up the area near the city gate to ensure safety, Zhu Wei convened his civil and military subordinates to hold a war symposium on the east gate tower of Puyang City.

At this time, the sky was already dark, and Cao Jun also lit bonfires around the fortresses in various blocks in the city to prevent Zhu Wei's sneak attack at night.

In this way, the various defensive fortresses of the Cao army in the entire Puyang City are also very obvious, and from the tower where Zhu Wei and the others are located, they can see the situation of most of Puyang City, and naturally they can also see the state of the Cao army in Puyang City.

"Princes, although our army has captured the outer city of Puyang, then Cao Cao intends to resist to the death in the city, and what should our army do next?"

Although Zhu Wei had the idea of setting fire to the city, on the surface, he still put on a posture of questioning these strategists and advisors under him, of course, if they had other better ideas, Zhu Wei could also consider accepting them.

"Lord, this battle may not be easy, now it looks like Cao Cao's layout in the city is also chaotic and orderly, it seems to be a hidden formation, our army must first explore the defense map of Cao Jun in detail, before we can find a solution!"

The relatively honest Lu Su looked at Cao Jun's arrangement in the city from afar, and seemed to see something, so he said with some warning.

"Lord, in fact, it doesn't matter, now that our army is here, as long as a few generals attack from several directions at the same time, then what means does the Cao army have, and it can't take care of each other, so naturally it can't cooperate, and it's only a matter of time before it breaks through Puyang City!"

Xu Shu said with a bit of radicalism, in his opinion, now that Zhu Weijun has many generals, he can completely push it over, and he doesn't have to worry about Cao Jun's arrangement.

It's just that their words didn't make Zhu Wei very satisfied, so Zhu Wei sighed and said, "Alas, it's just that if Cao Cao is stubborn, but he doesn't know how much our army will have to sacrifice to pacify this city!" The destiny of heaven is unpredictable, and after that, our army still has the battle of the Northern Expedition, if the loss here is too large, then the unification of the world will drag on for some time! ”

Jia Xu listened to Zhu Wei's words on the side, quietly looked at Zhu Wei's expression, and followed Zhu Wei's eyes to look at the fires in the city, and suddenly thought of something in his heart.

So Jia Xu stroked his beard a little and thought about it for a while, before he smiled and said, "Don't worry, my lord, although this Cao Cao is gathering troops in the city with the intention of resisting, he is actually trapped in the place of death!" Lord, if it is autumn today, it has not rained for days, and the weather is dry and dry, it is the time to use fire! Most of the buildings in this Puyang city are wooden, and Cao Cao has already driven the people in the city away, so our army can burn it, and it doesn't cost a soldier a single soldier, and Cao Cao is desperate! ”

"Your lord! There are still tens of thousands of lives in this city, although they are all Cao pawns now, but after all, they are human lives! If it is burned by fire, tens of thousands of lives will be burned, how can it be a tragedy! Lord, God has the virtue of a good life, so it's too cruel! ”

Listening to Jia Xu's words, Lu Su immediately spoke out against it, he could imagine that when the fire broke out, the entire Puyang City fell into flames, and now the Cao soldiers who looked at a glance would naturally be burned to ashes by the flames.

How can people bear such a miserable situation in the world.

But except for Lu Su, the others were just frowning and thinking, obviously still thinking about what kind of effect Jia Xu's fire attack strategy could have.

"Fire and water are ruthless, human life cannot be taken lightly, but now Cao Cao is stubborn, if our army attacks, it will also damage many lives! Zijing, Mr. Wenhe's strategy is also for our army's thoughts, but can you think about it again, or you can leave a glimmer of life for Cao Jun, if Cao Jun has a life, he can escape, if Cao Jun seeks his own death, then it is also his life! ”

Zhu Wei heard Jia Xu say his mind, of course he would not object, but Lu Su's words also made Zhu Wei have to consider the impact, you must know that when Bai Qi buried 200,000 Zhao Jun alive, the murderous reputation can be regarded as a legend through the ages, it can be seen that killing too many people at once by cruel means will also damage the reputation.

Therefore, while Zhu Wei roughly set up Jia Xu's fire attack plan, he also hoped that someone could come up with some methods to reduce Cao Jun's casualties in the flames.

"Don't worry, my army only needs to leave the main road in the city for Cao Jun to escape, and naturally we can do both!"

Jia Xu seemed to have thought of the possibility of setting the fire, so he spoke again, and then he explained in detail how to set the fire, how to leave a safe passage so that Cao's soldiers could escape from the fire.

Of course, Zhu Weijun will also set up a position outside the escape route, which can naturally easily make these escaped Cao soldiers feel at ease.

After listening to Jia Xu's words, Lu Su was speechless, after all, such a method could avoid Zhu Wei's army from attacking Cao Cao's stubborn formation, and it could also leave a glimmer of life for tens of thousands of soldiers of Cao's army, which was naturally the best way to capture Puyang City.

At the same time, in order to reduce the consumption of grain, grass and materials in the city and avoid the sluggishness in the command and transportation in the city, Cao Cao's earlier strategy of driving away the ordinary people in the city also made Zhu Weijun not have to worry about such a fire attack strategy would hurt the innocent, which naturally made the strategy of arson more acceptable.

So Zhu Weijun's final tactics for Puyang City were decided in this way.

On the second day, Zhu Weijun naturally sent someone to measure the direction of the wind, checked the celestial phenomena, and determined that there would be no rain in the near future, so he began to prepare for arson.

Many of Zhu Weijun's thunderbolt catapults were transported to various city walls, and these catapults would throw oil cans, firewood and grass into the city, which also saved Zhu Weijun's soldiers from going up to set fires.

In addition, all kinds of preparations to increase the fire are also underway, and naturally after the fire in the city, the fire will burn more and more, but Zhu Weijun has already occupied the outer city wall of Puyang City, so it is condescending to face all the neighborhoods in Puyang City, and many things are also much more convenient to do.

After a day of preparation, the preliminary means of arson have been prepared.

However, Zhu Wei did not set the fire immediately, but sent someone to send Cao Cao a final letter of persuasion to surrender, and at the same time asked people to shout words on the four city walls, so that the ordinary soldiers of Cao's army surrendered early.

Zhu Wei still gave Cao Cao a last chance......
