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

However, in order to completely enter the industrial age, it is far from enough to rely solely on the steel filling method. There are many other industrial systems that complement each other.

When Ma Jun saw the blueprint, his jaw almost dropped from shock.

Although Bai Feng had mentioned this to him before, he was still shocked when he saw it now.

Does this thing really exist?

Ma Jun could hardly believe his eyes.

These two blueprints are more precise, but the things they make are extremely small.

What the two drawings have in common is the black powder.

"Black powder? What the hell is this?"

Ma Jun rubbed his chin and murmured.

Bai Feng smiled lightly:

"Black powder, in simple terms, you can understand it as something that can burn."

"After ignition, the black powder will burn very regularly, producing a large amount of high-temperature heat energy, which can be used as the propellant for the firecracker and the grenade."

"Under certain circumstances, there will be an explosion."

"And the grenade uses this to explode the shell, and the small steel balls inside will scatter around."

"These small steel balls are basically the same as the bullets fired by the firecracker."

Ma Jun nodded thoughtfully.

He could only understand half of what Bai Feng said.

But it was also because of this that Ma Jun felt that these things were even more miraculous, and he also had the desire to create them.

In order to confirm that the steelmaking furnace was correct, Bai Feng continued to start it in the next few days, while Ma Jun observed to see if there was any problem.

Sure enough, in the past few days, Ma Jun discovered three small problems, most of which were parts problems, but the impact was not great.

Although you can't see it now, if you use it for a long time and the parts start to age, these things will easily loosen.

At that time, the steelmaking furnace will be in danger.

After that, Ma Jun didn't find anything abnormal again.

The steelmaking furnace also operates very smoothly.

After confirming, Bai Feng called hundreds of people in the barracks, and Qi Qi pulled the behemoth to the place where Bai Feng had applied to Boss Cao.

This is a wasteland, on the edge of the northern city gate.

Bai Feng deliberately divided this place to use it as a "military factory" in the future.

Ma Jun must not be the only craftsman in this military factory.

In this case, if we want to manufacture a large number of firecrackers and grenades, I am afraid that we will have to wait until the end of time.

Therefore, Bai Feng called the craftsmen who had come to help Ma Jun before, and wrote a letter to Cao Cao to allow them to pay.

In addition, Bai Feng also found many famous craftsmen in various places.

In just a few days, this temporary "military factory" has begun to take shape.

Chapter 460: Li Cunxiao's Battle with Sanying!

The establishment of a "military factory" is naturally built around the preparation of firearms.

Ma Jun and many craftsmen spent three full days studying the blueprints.

Three days later, Ma Jun and the craftsmen began to build.

In the past three days, the battle between Bashu and Hanzhong has become fierce.

After this period of time, Liu Bei also successfully marched from Jingzhou to Bashu, preparing to assist Bashu.

At this time, Zhang Fei and Guan Yu were riding on horses, looking fiercely at Deng Ai on the top of the city.

"Hey, Wuna kid, quickly open the door and surrender!"

"Otherwise, I'll have to poke a few transparent holes in your body!"

Zhang Fei cursed at Deng Ai.

Deng Ai smiled indifferently, ignored Zhang Fei, but looked into the distance.

Cao Jun's main force, which should have appeared long ago, has not yet arrived.

But according to the urgent report sent by the king of Wei yesterday, it should arrive today.

No matter what, he must stick to the city.

If the city is lost before the main force of Cao's army arrives, all the efforts during this period will be in vain.

Zhang Fei cursed for a long time, and suddenly felt dry mouth.

Guan Yu on the side snorted coldly and said:

"Third brother, why talk nonsense with him?"
