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

Bai Feng smiled and said:

"Sir, there is actually no need for such a great pressure."

"For the first time, how could it be so perfect?"

"It's not a dud, it's already very good, and the power can be guaranteed, which means that the direction is right."

"In terms of ignition time, you can see if the internal structure is not in contact with the black powder for some reason."

"The black powder is slow to ignite, so the grenade must be slow to explode."

"It exploded in thirty seconds, indicating that there was insufficient oxygen in the middle to cause combustion."

Hearing what Bai Feng said, Ma Jun suddenly felt confused:

"What is oxygen?"

"Don't you need this thing called oxygen for combustion?"

"But on the drawing, there is no such thing as oxygen. Where can I get it?"

Bai Feng smiled and said:

"What we breathe is called air, and it contains oxygen."

"Oxygen, you understand it as a very flammable gas."

"If it is in a closed space, there will be no air and no oxygen, so the explosion will be so slow."

"You just expand the compact form factor to make sure the oxygen explodes inside."

Now Ma Jun understood.

Just leave some space, isn't it all right if there is air in it?

Bai Feng explained the meaning of the word "air" for a long time.

But fortunately, it is finally explained.

After Ma Jun understood, he hurried back to the military factory, summoned the craftsmen who studied the grenade, and told them the news.

Only then did Ma Jun feel that he was a little too impatient.

You can't be too impatient to create this thing yourself.

I can't eat hot tofu in a hurry. It's not good to be in such a hurry.

Of course, Ma Jun didn't make light grenades during this time.

With so many craftsmen, it is natural to assign a group of people to make firecrackers.

Both are indispensable, and each is needed on the battlefield.

Grenade is responsible for destroying most of the enemies.

But definitely not clean.

At this time, it is necessary to use the firecracker.

According to what Bai Feng said.

Firecrackers can easily deal with soldiers, as long as they are accurate enough, they are more accurate and more powerful than bows and crossbows.

Moreover, as long as it is an excellent crossbowman, not to mention Huang Zhong and Qin Liangyu, it is an ordinary crossbowman leader, as long as he knows how to use it, he can use the firecracker to perfection.

After all, the threshold for a firecracker to aim is much lower than that of a crossbow.

It's just that firecrackers are more precise and difficult to manufacture than grenades.

When the firecracker was produced, news came from Cao Cao that most of Bashu had been wiped out.

And the Bashu army was trapped outside the city for half a month, unable to break through the line of defense no matter what.

Soon, it was time to test the firecracker.

The most important thing in the gun test is to see if the bullet will jam.

Once a jam occurs, the entire firearm will be unusable and will have to be repaired again.

After Bai Feng tried this, the problem of jamming did not appear, which meant that the firecracker was quite well made.

However, when testing ten rounds of bullets, the chamber exploded.

Fortunately, Bai Feng reacted quickly enough to drop the firecracker at the moment the chamber exploded, and survived.

Bursts, like jams, are fatal flaws.

Therefore, Bai Feng gave Ma Jun the direction of improvement and continued to develop the firecracker.

Other than that, there are no other flaws.

However, it was at the time when the fire gun was re-improved that the improved version of the grenade came out.

Detonation time, correct!

Power, unmistakable!

After testing, about four or five grenades were used, all of which reached Bai Feng's standard!
