Three Kingdoms: Liu Daer Was Forced Out of the Mountain at the Beginning

"boom!"

Just when everyone was looking forward to it, the grenade exploded.

A huge roar echoed through the sky, and the steel balls inside exploded instantly.

The surrounding soldiers clearly saw that the mountains of sandbags around them were instantly penetrated, and the sand continued to flow out.

After the explosion, a huge crater was left on the spot.

The soldiers suddenly took a breath of air.

If you use this on the battlefield, it will definitely be a big killer!

If there were people around such a big pothole, wouldn't they be blown away?

And the marbles that pop out can hit even heavy sandbags.

If it were a human being, he wouldn't be able to bear it even if he was wearing armor.

Ma Jun was also shocked by this huge power.

In fact, Ma Jun was mentally prepared when he started making it.

However, when he saw the power with his own eyes, he still felt incredible.

This thing is simply too powerful!

However, Bai Feng frowned and sighed softly.

"Sir, isn't this powerful enough?"

Ma Jun suddenly said in confusion:

"If this thing explodes on the battlefield, it can take away countless enemy troops!"

"If there were more than one, I'm afraid they would have been blown to pieces before the enemy troops came over."

Bai Feng shook his head helplessly and said:

"The power is pretty good and has met my expectations."

"Why is the delay of this grenade so high?"

"Do you think that when the two armies are facing each other, and the enemy suddenly throws such a strange thing at you, what would you do?"

"Why don't we just stop fighting and get together to see what's going on?"

Hearing this, Ma Jun suddenly blushed.

This is definitely impossible!

During a battle, if the enemy throws something at you, your first reaction will definitely be to continue fighting.

No matter how far this thing is thrown, it can't kill anyone.

At most it's a joke.

But even if he went over to take a look out of curiosity, the explosion took away a group of people.

But this method works once, what about twice?

The enemy will definitely run away after seeing it.

By the time this thing explodes, I'm afraid the day lilies will be cold.

"A normal grenade must have at least ten seconds of explosion time, excluding the time it takes to linger in the air."

"Otherwise, where would it be enough?"

"This must be improved, otherwise this grenade will not work at all."

Lin Chuan smiled bitterly.

Ma Jun immediately nodded and said:

"Please rest assured, sir, I will definitely improve!"

Ma Jun was originally very confident in the grenade he made, but he did not expect that there would be such a big flaw.

It seems that a more careful inspection is needed.

Bai Feng smiled and said:

"Sir, you don't actually need to be under so much pressure."

"How could it be so perfect when it was first made?"

"It's already pretty good if it's not a dud. If the power is guaranteed, it means the direction is right."

"As for the ignition time, just check whether the internal structure caused the fuse to fail to contact the black powder for some reason."

"Black powder ignites slowly, so this grenade will explode slowly."

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

Listening to what Bai Feng said, Ma Jun suddenly felt confused:

"What is oxygen?"

"Does combustion still require this thing called oxygen?"

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

Bai Feng smiled and said:

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

"Oxygen, you understand, is a very flammable gas."

"If it was in a closed space, there would be no air and no oxygen, so it would explode so slowly."

"You just need to expand this compact shape to ensure that oxygen enters and explodes."

This time Ma Jun finally understood.

Just leave some space, wouldn't it be ok if there is some air inside?

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

But fortunately, it was finally explained.

After Ma Jun understood, he quickly returned to the military factory, summoned the craftsmen who were researching grenades, and told them the news.

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

Don't be too impatient when creating this thing yourself.

I can't eat hot tofu if I'm in a hurry, but it's not good if I'm in such a hurry.

Of course, Ma Jun didn't just make grenades during this period.

There are so many craftsmen, so naturally a group of people have to be divided into making fire guns.

Both are indispensable, each is needed on the battlefield.

Grenades are responsible for taking out most enemies.

But it definitely won't be cleaned up.

At this time, it’s time to use the firecracker.

According to Bai Feng.

Fireguns can be easily dealt with against stray soldiers, as long as they are accurate enough, they are more accurate and more powerful than crossbows.

Moreover, as long as you are an excellent crossbowman, not to mention the type of Huang Zhong and Qin Liangyu, you are an ordinary crossbowman commander. As long as you can use it, you can use the fire blunderbuss to perfection.

After all, the threshold for aiming a fire blunderbuss is much lower than that of a crossbow.

However, firecrackers are more precise and difficult to make than grenades.

When the fire blunderbuss was made, news came from Cao Cao that most of Bashu had been wiped out.

As for the Bashu army, they were trapped outside the city for half a month and could not break through the defense line.

Soon, it was time to test the firecrackers.

When testing a fire gun, the most important thing is to see if it will jam.

Once a bullet jams, the entire gun will no longer be usable and will need to be repaired.

After Bai Feng tried this, the problem of bullet jamming did not occur, which showed that the fire gun was relatively well-made.

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

Fortunately, Bai Feng reacted quickly enough and dropped the gun as soon as it exploded, so he survived.

Bore blasts and jamming are both fatal flaws.

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

Other than that, there are no other flaws.

But it was also when the firecrackers were being improved that an improved version of the grenade came out.

Detonation time, correct!

Powerful, unmistakable!

After testing, about four or five grenades were used, and all of them met Bai Feng's standards!

The grenade belonging to Wei Dynasty was finally made!

Ma Jun was immediately excited and quickly asked if there was anything that needed to be improved.

However, Bai Feng shook his head.

This grenade is enough.

The current Wei Dynasty cannot produce other variants of grenades.

The issue that worries me most now is no longer a technical issue.

Forged steel is mature and manufacturing is mature.

There was no shortage of black powder either.

What is lacking now is iron.

Iron is the source of everything. Without iron, everything is in vain.

After all, iron is not only used for grenades and firecrackers.

Armor, weapons, war horses and armor all require a large amount of iron.

At this time, it is necessary to start mining the iron ore.

After getting Cao Cao's permission, Bai Feng took action.
