Shi Kun's face flushed, and he straightened his neck and said: "So what, we didn't know the instructor's kindness before, but now that we know, we naturally have to listen to the instructor." ”

"You kid ......."

"Shut up!" Lu Jincai let out a loud shout, interrupting the quarrel between the two.

At this time, another soldier said: "It's all on the same boat, what's the noise?" Let's think about how to win the generals of the party. ”

"That's right, but how do you win? The instructor trains the queue every day, and he doesn't let us practice anything else. ”

"You can't say that, haven't you seen the envy in the eyes of those onlookers when we stood in line these days?"

"Hey...... Oh, yes, I found out. ”

"I saw it too."

"The instructor is indeed capable of something, let's go to that station now, and the momentum is obviously different from usual."

"Does it work? When the time comes, it will not be as good as the queue. ”

So, the anger that had just been puffed up was vented again, and everyone fell silent.

Shi Kun said: "I think the instructor is right. Isn't the end gun that started training today just training to shoot accurately? ”

"That's right, it's just like that, when General Fang was training before, he didn't train like this. Maybe we'll win by then. ”

Shi Kun said: "Anyway, try your best to practice according to the instructor's method, and the instructor must have a number in his heart to win or lose." ”

"Also, dead horses are treated as live horse doctors."

Lu Jincai suddenly spoke: "Listen to the instructor, just call him to death...... I tell you, whoever dares to cheat and cheat, and if they lose the competition, they will be beaten to death one by one. ”

This sound was quite domineering, making the other people break out in a cold sweat on their backs, just imagine, this is a bull who even General Chi Yidaochi can do.

Shi Kun suddenly proposed, "Or ...... Let's change the nickname for the instructor? ”

This proposal attracted everyone's consent, and now Wu Zheng's identity is difficult to understand, and no one wants Wu Zheng to know about the indecent nickname.

"The ferocity must not be able to scream."

"Yes. Except for the elimination of the two on the first day, the instructor is still kind these days. ”

"In fact, what satisfies me the most is that the instructor does what he says and cashes in on the money...... Ha ha. ”

"There is money in the family."

"Landlord."

"Not bad."

So without Wu Zheng's knowledge, the nickname became "trustworthy landlord" again.

……。

I have to say that these days of training have given the image of these soldiers a makeover.

Between their gestures, they have the demeanor of professional soldiers.

Of course, these people are the best among them.

Under the sideways glances of their former comrades, who were also recruits, they unconsciously gave birth to a sense of honor as soldiers.

They feel that they are different from others.

This is a kind of momentum, a momentum that can make people strong, and a momentum that can make people no longer afraid of any pressure.

The sword, in hand, asks the world who is the hero's momentum.

This kind of momentum has attracted the trained recruits, as soon as they have free time, they will run to their side.

Some even spontaneously steal school and go back to practice on their own.

On the twelfth day, when all men could hang two hundred copper coins from their guns, and could lift them smoothly for half an hour.

There was no suspense, and Wu Zheng listed it as a regular training subject.

The new training is live ammunition shooting.

But the first class was in the house.

The three-point-one-line, a method known to everyone in later generations, was a novelty in this era when even muskets were not popular.

The best of these people are very receptive.

The shooting after class made Wu Zheng very satisfied, the distance of thirty steps, no one missed the target, the distance of fifty steps, the missed target was only thirty percent, of course, eighty steps, this distance Wu Zheng just tried, the result is no longer important, because Wu Zheng is not interested in training sniper officers.

Two days later, on the fifteenth day, Wu Zheng started the class again.

In the second lesson, the amount of advance on a moving target is taught, and the amount of the bullet falling in a parabolic line after a long flight to raise the muzzle of the shot.

After the class, Wu Zheng did not instruct the soldiers in live ammunition shooting.

Instead, they went to the military workshop, because Xu Shoujie and Qi Daokun had already trial-produced grenades, and they had already gone through the first test.

What Wu Zheng saw was the result of an improvement.

This is a product that is not quite the grenade in Wu Zheng's memory.

The warhead is in the shape of a goose egg, but much larger than a goose egg, and the cast-iron shell, the surface is engraved with cross twills as ordered by Wu Zheng.

The handle is also a wooden handle according to Wu Zheng, but it is very long, about 20 centimeters.

Looking at this, you know that this amount is far heavier than imagined, and there is no doubt that Wu Zheng is disappointed in his heart.

But in order not to dampen the enthusiasm of the craftsmen, Wu Zheng still smiled and encouraged, and then asked Qi Daokun: "How much does this grenade weigh?" What is the size? After the test explosion, how powerful is it? ”

Qi Daokun replied: "The grenade weighs two and a half catties, of which the warhead part weighs two catties, the iron shell is half a catty, the charge is one catty and six taels, and the wooden handle part is about four taels, which is filled with flint for igniting the fire rope." The size is, according to the prince's meter ruler, the warhead is seven centimeters, the wooden handle is twenty centimeters, minus the two centimeters that the warhead and the wooden handle fit, a total of 25 centimeters. ”

Wu Zheng thought to himself, it is really so long, too heavy and too long, this throw, it is like a short branch rolling in the air, how hard it is, it is estimated that it will not be far.

"After the test explosion, how is the power?"

Chen Shoujie replied: "The power is far greater than estimated, within three meters, the fragments can pierce the armor, and the left and right sheep will die." ”

This is satisfying to Wu Zheng, black powder, Wu Zheng's expectations are not so high, and it is already good to have a killing range of one zhang square.

Wu Zheng bowed his head slightly, and continued to ask: "Is the burning time of the fuse long enough to ignite and throw?" ”

Qi Daokun replied: "After improvement, it is enough, but it is just a rope flint, not every time it can ignite the fuse, it still needs to be improved." Therefore, in order to ensure ignition, two flints and two drawstrings were placed in the hole of the wooden handle. ”

Wu Zheng said: "Then try the explosion once, and let this king see the power of the explosion." ”

So, I came to the empty field.

For the sake of safety, no one was sent to conduct a trial vote.

Instead, the grenade is fixed on the ground, and then the test equipment such as livestock and armor are arranged.

Then use a long rope to lead it to a distance of 30 meters and detonate it.

The rope pulled, and a puff of light smoke began to rise.

Wu Zheng silently estimated, and in about ten seconds, the smoke became thicker, indicating that the black powder that had ignited the warhead had been ignited.

The explosion principle of black powder is different from that of yellow powder, black powder is a physical reaction, the combustion of sulfur, nitrate, and charcoal instantly generates a large amount of gas, forming a strong air pressure, acting on the projectile, and then bursting out.

Black powder is inferior to yellow powder in that the detonation speed of black powder is slower than that of yellow powder, and under normal circumstances, there will be a delay of two or three seconds after igniting the recharge.
