The gunpowder exploded, but the two were not harmed.

Qin Fan said to Li Shimin:

"I said that the first display was to be exciting, and this is why it is powerful."

"And this one, I have the amount of gunpowder to control, and the natural power is small."

As he spoke, he walked forward, stepping through the billowing smoke to the place where the gunpowder had been prevented.

Li Shimin hurriedly said: "Brother Qin, there may still be danger ahead, it's better to wait for the smoke to clear." ”

Qin Fan waved his hand and said, "It's okay, this gunpowder has already been blown up, there won't be anything!" ”

When Li Shimin heard this, he had to grit his teeth and keep up.

But in my heart, I was still very wary.

I was unharmed by such a big explosion before, and if I was killed by the explosion at this time, it would be too unjust.

However, the gunpowder has already ignited and exploded, and Li Shimin's worries will naturally not become a reality.

He came to Qin Fan.

"Look!" Qin Fan pointed to the two big pits on the ground, one large and one small.

"This one is the one that left the marks of the first explosion, when the smoke has cleared more than halfway through."

"And the lighter one that's still smoking is the smaller explosive we detonated the second time."

"There is a difference in the amount of explosives contained in the two, and the power naturally changes."

When Li Shimin heard this, he nodded and said, "If the power is controllable, then it can be used for mining." ”

Qin Fan nodded and said, "Not only that, but it is to dig a mountain and dig a road, and this explosive is also very good." _o_m ”

Hearing this, Li Shimin's eyes lit up: "Can it be used not only for mining? ”

Qin Fan smiled and said, "Why stop here? This gunpowder has a great effect! ”

Hearing this, Li Shimin's eyes moved, and he couldn't help asking: "Can it be used to retreat from the enemy?" ”

Qin Fan smiled: "Lao Li, I can't see that you are still a war maniac!" ”

Li Shimin ignored Qin Fan's ridicule, and just asked, "Can you use this?" ”

"Not to mention retreating from the enemy, if gunpowder is used in battle, it can completely carry out a weapon innovation!"

"Weapon innovation?" Li Shimin is a little confused, innovation? Whose life is the revolution!

"Yes, nowadays, the swords, guns, swords, halberds, clubs, spears, bows and crossbows we use are all cold weapons."

"Cold weapons?" Li Shimin was a little puzzled.

"Is this weapon hot or cold?"

Qin Fan nodded and said, "Not bad!" And the use of gunpowder is driven by hot weapons! ”

"Guns and artillery, mines, etc., ......"

When Li Shimin heard this, his eyes couldn't help but light up: "What are these things, tell me quickly." ”

Qin Fan began to introduce them one by one:

"Do you remember the pebble that flew towards us earlier?"

"Naturally remember! If it weren't for Brother Qin's knocking it away, I'm afraid the two of us would have been injured. ”

Qin Fan raised his hand, took off the saber from his waist, and handed it to Li Shimin: "Take a look!" ”

Hearing this, Li Shimin was a little puzzled, but he still took the saber and pulled it out.

But at this glance, he was dumbfounded.

"Knife edge, cracked?"

"Not bad." Qin Fan nodded.

"This is still the saber carefully crafted by the blacksmith I ordered, and it is not at the same level in strength compared to the swords used by ordinary soldiers on the battlefield."

"But even so, after knocking those pieces of rubble, it still made a gap, and even almost broke!"

"That's the power of gunpowder!"

"If you put this stone into a round boring, stuff enough gunpowder into its back, and ignite the gunpowder, and this stone shoots out, killing people is not a problem, right?"

Qin Fan assumed.

"Even Brother Qin's saber can be broken, it shouldn't be difficult to kill someone!"

Li Shimin said.

"It's just that if the other party is wearing thick armor, I'm afraid this stone will be difficult to build."

Qin Fan shook his head: "Not necessarily! ”

Hearing this, Li Shimin's eyes couldn't help but light up: "Brother Qin still has something to say?" ”

Qin Fan nodded and said, "Not bad!" ”

"First of all, the stone that was shot at us just now,. (This chapter is not finished!) )

Chapter 141: Money Darts to Flying Locust Stones

It was shattered by the explosion of explosives. Some of the power of the explosives is lost when it blows up the rocks. ”

"And how many stones did this whole explosive shoot? We're just one of them. ”

"The way I said before is to concentrate the power on one point, if that's the way. _o_m Both the power and the rate of fire will be much faster! ”

"Secondly, we assumed that it was a stone, but if we used iron instead of stone, what do you think would be the effect?"

Hearing this, Li Shimin's eyes couldn't help but light up: "The power of the money dart is naturally far better than the flying locust stone!" ”

When Qin Fan heard this, he couldn't help but be speechless.

What a metaphor these are!

But the good thing is that the meaning is not bad.

So, he continued: "When gunpowder and iron particles are placed in the chamber of a gun, and then the weapon is ignited at the target, it is a gun. ”

"A spear is far more powerful than a bow and arrow."

"If the Tang Dynasty soldiers and horses are equipped with guns, whether the enemy is a Hun on a horse, or a Roman soldier in strong armor."

"A salvo is enough to make them flee in fear."

Hearing this, Li Shimin was stunned: "If a round of salvo can't make a contribution, wouldn't it be a matter of waiting?" ”

Hearing this, Qin Fan smiled lightly: "One round is not good? What about those two rounds? ”

"If it doesn't work again, three rounds! Four wheels! ”

"As long as there are enough bullets! The chamber of the gun is not overheated, and it is not a problem if you just want to shoot the enemy into a hornet's nest! ”

Hearing this, Li Shimin couldn't help but be surprised: "Isn't this gun like a bow and arrow, which needs to be filled with ammunition?" ”

When Qin Fan heard this, he couldn't help but look at Li Shimin with admiration.

Although this person is a Tang person, he has a lot of opinions about many weapons of later generations.

"In the more primitive gun, after a salvo, the gun will heat up and it will be difficult to continue."

"If you want to reuse, you have to wait until the chamber has cooled, then clean up the remaining residue in the chamber, refill it with gunpowder, fuses, and stuff in bullets before you can use it again."

Hearing this, Li Shimin was not disappointed.

What Qin Fan said was the most primitive gun.

"What about the non-primitive?"

"There is a gun, called a machine gun, which is fixed in one place and can fire twenty rounds in the blink of an eye!"

Hearing this, Li Shimin couldn't help but open his mouth wide!

Twenty rounds in one second! Wouldn't it take less than half a stick of incense to kill all the troops of 10,000 people?

(One stick of incense lasts for 2 quarters of an hour, about 30 minutes)

It is the most skillful executioner, the knife falls in his hand, the knife is blunt, and the blood is so strong that it is difficult to reach the tenth and twelfth of it.

Qin Fan knew what he was calculating with Li Shimin's expression.

So I couldn't help but pour a basin of cold water.

"If you want to build a machine gun, it's still far away! Today's Datang is the most primitive kind of gun I said before, and it can't be made! Even if it is forcibly made, there is a chance that it will blow up. ”

"Explode?" Li Shimin was slightly stunned.

"It's the explosion of gunpowder, which shatters the chamber of the gun!" Qin Fan explained.

Hearing this, Li Shimin's back was cold.

They were fifty meters away, and the flying bullets could shatter the saber.

If it is close to being blown up, will the man with the gun have no bones?
