When Ma Jun saw this, he couldn't help being shocked, and quickly took it over for a closer look.

But after watching for a long time, Ma Jun suddenly frowned slightly, his face a little dignified:

"This... is a weapon."

After all, Ma Jun shook his head helplessly:

"My lord, if it's armor and equipment, a certain is better at it."

"But a certain person has been studying armor and equipment all the year round, but he is..."

After all, Ma Jun scratched his head in embarrassment.

This involves his knowledge blind zone.

Bai Feng sighed softly.

It seems that it is the same as I thought.

There is a specialization in the art industry, and this kind of thing can't be created just by wanting to make it.

If there is a military thorn, then in hand-to-hand combat, Cao Wei's army is invincible!

This thing bleeds quickly and is not easy to heal. Once stabbed, it can basically be declared dead.

What's more, this is still in ancient times.

Even if Hua Tuo was beside him, he couldn't save it at all.

But there is no way. You can't have both fish and bear's paws. Bai Feng wants to have them all, and he has to wait for a while.

At the very least, you have to wait until you reach Liu Bei before you can play Pu Yuan's idea.

Originally, Bai Feng didn't have much certainty to dig Pu Yuan from Liu Bei.

But after seeing Ma Jun's reaction, Bai Feng was at least 60% more sure.

The craftsman of this era is very energetic, if he himself gave Pu Yuan drawings, he might not be tempted.

...

One day passed quickly.

The steelmaking furnace rang all day, during which the guards continued to add raw materials to it according to Bai Feng's instructions.

Soon, the steelmaking furnace slowly ceased operation.

Hundreds of forged steel slowly came out of the furnace.

Ma Jun couldn't wait to rush over to check the results of forging.

"One hundred forged steel is one hundred forged steel!"

"No, it's better than the hundred forged steel that a certain person saw before!"

Ma Jun was immediately overjoyed, and his expression became more and more surprised as he watched the more and more steel shipped out.

It looks like it's definitely more than a thousand catties!

No... still shipping out!

Soon, all the steel forged in the steelmaking furnace was taken out.

The guards finally got the result after some calculations.

Ten thousand eight hundred catties!

Ten thousand catties per day!

"My lord does not deceive me! Really produces ten thousand catties per day!"

Ma Jun felt that he was simply dreaming for a while.

And this dream is extremely real.

Nissan produced a million catties, this kind of thing that I didn't even dare to think, actually happened!

If Ma Jun heard anyone bragging that they could produce a thousand catties of steel a day, he would have to slap him on the head.

Not to mention ten thousand catties?

"Yes, it looks like it can be used."

Bai Feng took a brief look at the steel, there was no impurities, it was perfect.

Each step is strictly in accordance with Bai Feng's requirements. Not only is the steel produced without impurities, it is even better than Bai Feng expected.

This is more than 100 forged steel.

If it takes longer to irrigate in the steelmaking furnace.

I am afraid that these steels will easily become thousands of forged steels!

Thousands of forged steel is something that almost exists in the legend.

It is said that the raw material of the Blue Night Sword seems to be a steel material that is relatively similar to Qian Forged Steel.

If energy produces the Blue Nightmare Sword, every Cao Wei soldier has one in his hand.

That close combat, no matter what weapon you encounter, can it be easily confronted?

Even though he said that, Bai Feng is still thinking of what swords.

Now, the raw materials for fire guns and grenade are available!

As long as you have steel and black powder is easy to handle, then fire guns and grenades can be made!

Before Ma Jun could speak, Bai Feng gave Ma Jun the drawings of the fire gun and the steel ball grenade.

Among them, there is a refining drawing of black powder.

To make thermal weapons, black powder is indispensable.

Although black powder was one of the four great inventions in ancient times, it did not appear until the late Tang Dynasty.

At that time, the black powder was invented because of alchemists' alchemy.

It was not until the Ming Dynasty that black gunpowder began to be officially used, opening the era of thermal weapons.

With black powder and steel, infinite possibilities can be created!

It's not just fire guns and grenades.

Cannons, mortars, etc. are all possible!

Even with the steel filling method, Cao Wei touched the threshold of the industrial age.

However, if you want to fully enter the industrial age, it is far from enough to just fill the steel method. There are many other industrial systems that complement each other.

When Ma Jun saw the drawing, his jaw almost fell out of shock.

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

Does this thing really exist?

Ma Jun could hardly believe his eyes.

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

And the common point of the two drawings is this black powder.

"Black powder? What the **** is this?"

Ma Jun rubbed his chin and murmured.

Bai Feng smiled lightly:

"Black powder, in simple terms, you can understand it as a combustible thing."

"After being ignited, the black powder will burn very regularly, producing a large amount of high-temperature heat, which can be used as a propellant for the firecrackers and grenade ~ lightnovelpub.net~ Under certain circumstances, it will explode."

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

"These small steel **** are basically the same as the bullets fired by the firecrackers."

Ma Jun nodded thoughtfully.

Bai Feng could only understand half of what Bai Feng said.

But that's also the case, Ma Jun felt that these things were even more magical, and he also had the desire to create them.

In order to confirm the correctness of the steelmaking furnace, Bai Feng continued to start it in the next few days, while Ma Jun was observing to see where there was a problem.

Sure enough, in the past few days, Ma Jun discovered three minor problems, most of which were part problems, but the impact was not significant.

Although it can't be seen now, if it takes a long time and the parts begin to age, these things will loosen easily.

The steelmaking furnace at that time will be in danger.

After that, Ma Jun found no abnormalities again.

The steelmaking furnace also operates very smoothly.

After confirmation, 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 specifically divided this area into a future "army factory."

The craftsmen in this military factory certainly cannot use Ma Jun alone.

In this case, a large number of fire guns and grenades have to be made, and I am afraid that it will not wait until the sky is old.

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

In addition, Bai Feng also found many famous craftsmen everywhere.

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