"boom!"

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

A huge roar resounded through the sky, and the steel **** inside exploded instantly.

The soldiers around clearly saw that the sandbags piled up around him were pierced instantly, and the sand kept flowing out.

After the explosion, a huge crater was left in place.

All the soldiers suddenly took a breath of air-conditioning.

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

If there are people around such a big hole, wouldn't it be blown away directly?

And the marbles that popped up can hit even heavy sandbags.

If you are a human, you can't hold it even in armor.

Ma Jun was also shocked by this huge power.

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

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

This thing is simply too strong!

However, Bai Feng frowned and sighed softly.

"My lord, isn't this power enough?"

Ma Jun suddenly puzzled:

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

"If there are more than one, I'm afraid it will be destroyed before the enemy comes over."

Bai Feng shook his head helplessly and said:

"The power is good, and it has met my expectations."

"Just why does this grenade have such a high delay?"

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

"Don't fight anymore, gather together to see what it is?"

Hearing this, Ma Jun's face immediately blushed.

It must be impossible!

When the enemy threw something in the war, his immediate reaction would definitely be to continue the war.

No matter how far away this thing is, it won't kill anyone.

See it as a joke at best.

But even if it was because of curiosity, he leaned over and took a group of people away.

But what about this method once, twice?

The enemy will definitely avoid it after seeing it.

When this thing explodes, I'm afraid the day lily will be cold.

"Normal grenades, except for the time spent in the air, have at least ten seconds to explode."

"Otherwise, where is enough?"

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

Lin Chuan smiled bitterly.

Ma Jun nodded immediately:

"My lord, rest assured, I will definitely improve!"

Ma Jun was still very confident in the grenade he made, but he didn't expect that there would still be such a big mistake.

It seems that a good inspection is needed.

Bai Feng smiled and said:

"Mr. actually doesn't need such a lot of pressure."

"Where is it so perfect for the first time?"

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

"For the ignition time, you can see if the internal structure is due to some reason that the fuse fails to contact the black powder."

"Black powder ignites slowly, and this grenade must 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 in the mist:

"What is oxygen?"

"Does it require this thing called oxygen to burn?"

"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, which contains oxygen."

"Oxygen, you understand it as a very easy to burn gas."

"If it is in a closed space, there is no air and no oxygen, so it explodes so slowly."

"You just need to expand this compact shape and make sure that oxygen will explode inside."

This time Ma Jun can be regarded as understood.

Just leave some space, can't it be enough if there is air in it?

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

Fortunately, the explanation finally came through.

After Ma Jun understood, he hurriedly returned to the military factory, summoned the artisans who were studying the grenade, and told them the news.

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

If you create this thing yourself, you can't be too impatient.

I can't eat hot tofu if I am anxious.

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

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

The two are indispensable, each of which is needed on the battlefield.

The grenade is responsible for destroying most of the enemies.

But it must not be cleaned up.

At this time, fire guns are going to be used.

According to Bai Feng.

Fire guns can be easily solved against drifting soldiers, as long as they are accurate enough, they are more accurate and more powerful than crossbows.

Moreover, as long as it is an excellent crossbowman, not to mention Huang Zhong Qin Liangyu, it is an ordinary crossbowman.

After all, the threshold that the firecrackers need to aim at is much lower than that of a crossbow.

However, fire guns are more precise and harder to manufacture than grenade.

When the firearms were created, news came from Cao Cao that most of Bashu had been wiped out~lightnovelpub.net~ and the Bashu army was trapped outside the city for half a month and could not break through the line of defense. .

Soon, it was time to test the firecrackers.

The most important thing in the fire gun test is to see if it will get stuck.

Once a jam occurs, the entire firecracker will no longer be usable, and it will need to be repaired again.

Bai Feng tried this way, but the problem of stuck bullets did not appear, indicating that the firecrackers were relatively well-made.

However, when testing ten bullets, it exploded.

Fortunately, Bai Feng reacted fast enough and immediately threw the fire bludgeon down at the moment it exploded, so that he was spared.

Bursting and jamming are fatal flaws.

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

Apart from this, there are no other defects.

However, it was at the time when the firecrackers were 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!

The grenade that belonged to Wei was finally made!

Ma Jun was immediately excited, and quickly asked if there were any areas that needed to be remodeled.

However, Bai Feng shook his head.

This kind of grenade is enough.

Other variants of grenade can not be made by the current Dawei.

The problem that I worry about now is no longer a technical problem.

Forged steel is mature and manufacturing is mature.

There is no shortage of black powder.

What is lacking now is iron.

Iron material is the source of everything, without iron material, everything is in vain.

After all, iron is not only for grenade and firecrackers.

Armor, weapons, and battle vests all require a lot of iron.

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

After getting the permission of Cao Cao, Bai Feng began to act.
