Three Kingdoms: Liu Daer Forced out of the Mountain at the Beginning

He didn't expect that Deng Ai didn't play his cards according to the routine!

Originally, he would not fight behind closed doors. In this case, even if Deng Ai came aggressively, he might not be able to break through the city.

After all, even if it is the city defense army, the Bashu border guards are extremely strict.

It is simply impossible for a mere [-] soldiers to break through the city.

But Liu Zhang didn't expect it at all, and it can be said that he underestimated the abilities of Li Cunxiao, Li Yuanba and Qin Liangyu.

The three of them were like no man's land, using the siege arrows fired by the siege ballista, they directly led the army to climb up the city wall.

In just a quarter of an hour, the three generals climbed up the city wall together.

How can the city defense army beat them?There will be a steady stream of Cao Jun entering the city behind.

Immediately, the city defense army suffered countless casualties, and they couldn't resist Cao Jun's pace at all.

In half an hour, Bashu's first line of defense was directly taken down!

Liu Zhang was in a hurry!

Chapter 450 The Importance of Steel

At this time, in Xuchang.

Bai Feng was leisurely watering the crops in the farmland.

The crops are growing very well during this time.

Although this mansion has been abandoned for a long time, the land is indeed the most fertile in Xuchang.

During this period of time, Cao Jie often came to find Bai Feng and help Bai Feng water together.

After all, now Bai Feng has sent Yanyun Eighteen Cavalry, Li Cunxiao, Li Yuanba, and Qin Liangyu to attack Bashu with Deng Ai.

The farm work in this farmland can only be done by Bai Feng himself.

But after all, there are only five acres of land, and these crops only need to be watered, and there are no special requirements.

There's no need for deworming or anything like that.

The seeds given by these systems are completely free from insects.

After pouring the water, Bai Feng had nothing to do, so he opened the system mall to see what else could be used.

I have to say that the current system mall is much better than the previous one.

After improvement, it is estimated that the system also understood that the previous path was wrong, so it directly eliminated all the things that strengthened its own strength.

The rest are things that can be used as subjects instead.

Among them are many things that will only appear in modern or later generations.

Not only food, but even blueprints for firecrackers.

It's just that let alone Cao Cao, even if Bai Feng does it himself, he can't make a firecracker.

Thermal weapons are not something that can be made just by thinking about it, and it requires the cooperation of a very large and huge industrial system.

At the very least, there should be steel and the ability to produce parts, so that the firecracker can be made.

Otherwise, how could these things be made out of nothing?

After a general look, Bai Feng locked on a very good thing.

How to use black powder!

This is the only way to use thermal weapons that can be used now.

Black gunpowder can actually be manufactured since the Three Kingdoms period.

It's just that now is the era of cold weapons, and everyone doesn't have the idea of ​​hot weapons at all.

Everyone's thinking is still stuck in either hand-to-hand combat or shooting with arrows.

At most, there will be some construction machinery and catapults.

In fact, the catapult is similar to the cannon of later generations, but it is far less powerful than the cannon.

But even so, using this siege is extremely effective.

If black powder can be used to make something similar to a grenade, wouldn't it be possible to directly reduce dimensionality and attack Liu Bei and Sun Quan?

After all, even if Cao Jun's power is already very large, the number of people is also very large.

But fighting in the south is far less convenient than in the north.

The northern soldiers could not bear the southern climate alone.

What's more, we still have to fight on the river.

In this case, the strength of northern soldiers will be greatly weakened.

Of course, the same is true for the soldiers in the south. If they go to the north, they will not be able to stand the climate in the north, but they are much better than the northerners.

After all, to fight against the cold, you only need to stuff the armor with wool and other warm things.

But the soldiers in the north are different. Just being unaccustomed to the environment is a huge problem.
