Shi Kun blushed and said with his neck straight: "So what? We didn't know the instructor's kindness before. Now that we know, we naturally have to listen to the instructor."

"You boy..."

"Stop!" Lu Jincai shouted loudly, interrupting the quarrel between the two.

At this time, another soldier said, "It's all on the same boat, why are you quarreling? Think about it, how can you win General Fang and the others."

"That's right, how can I win? The instructor trains the queue every day and doesn't let us practice anything else. It's useless to just look good and it's just a flower stand."

"You can't say that. Is there any envy in the eyes of those onlookers when we were standing in line these few days?"

"Oh... I've said that, I've found it too."

"I saw it, too."

"The instructor is indeed capable of doing something. When we stand there, our momentum is obviously different from usual."

"Is it useful? Then it will not be better than the queue."

So, the breath that had just become bulging suddenly ejaculated and everyone became silent.

Shi Kun said: "I think the instructor is right. Isn't the gun that started training today just because the training is accurate?"

"That's true, that's the reason. General Fang didn't train like this before. Maybe we can win by shooting at that time."

Shi Kun said: "Anyway, you can try your best to practice according to the instructor's method, and the instructor must have a clear idea of ​​winning or losing."

"Yes, let's treat dead horses as live horses."

Lu Jincai suddenly said, "Listen to the instructor, just follow the orders from death... I tell you, whoever dares to be cheated and cheated will lose the competition, and they will beat you to death one by one."

This sound was quite domineering, which made the others sweat coldly on their backs. Just imagine, this is a great man who even General Chi Yidao could do.

Shi Kun suddenly suggested: "Why... let's change the instructor's nickname?"

This proposal attracted everyone's consent. Now Wu Zheng's identity is hard to be known, and no one wants to be known by Wu Zheng to get the indecent nickname.

"The evil demon must not be able to scream."

"Yes. Except for the two people who were eliminated on the first day, the instructors are still kind these days."

"Actually, what satisfy me the most is that the instructor will do his best and the money will be paid...haha."

“There is money at home.”

"Landlord."

"good."

So without knowing it, Wu Zheng's nickname became "trustworthy landlord".

....

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

They have the style of professional soldiers in every move.

Of course, these people are the best among the people.

With the comrades who were both new recruits looking sideways, they unknowingly developed a sense of honor as a soldier.

They feel that they are different from others.

This is a momentum that can make people stronger and can make people no longer fear any pressure.

With the sword in hand, I ask who is the hero in the world.

This momentum has attracted the trainees to run to them as soon as they have free time.

Some even spontaneously learn secretly and go back to practice on their own.

On the twelfth day, when everyone can hang two hundred copper coins at the gun, they can hold them smoothly for half an hour.

Without suspense, Wu Zheng listed it as a regular training subject.

The new training is live-fire shooting.

But the first class was inside the house.

Three points and one line, a method that everyone knows about later generations is a new thing in this era when muskets are not popular.

The best of these people have very strong acceptance skills.

The shooting after class made Wu Zheng very satisfied. No one had off-target at a distance of thirty steps. The distance of 50 steps was only 30% off-target. Of course, 80 steps, Wu Zheng just tried this distance, but the result was no longer important, because Wu Zheng was not interested in training sniper officers.

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

The second lesson teaches the advance amount of moving targets, the parabola descends after long-distance flight, and the increase in the muzzle.

After class, Wu Zheng did not guide the soldiers' live ammunition shooting.

Instead, they went to the military workshop because Xu Shoujie and Qi Daokun had tried to produce grenades and had already undergone the first test.

What Wu Zheng saw was the result of an improvement.

This is a product that is different from the grenades that Wu Zheng remembers.

The bullet is in the shape of a goose egg, but it is much larger than the goose egg. The cast iron shell has crossed twill engraved on the surface as Wu Zheng told him.

The handle is also the wooden handle mentioned by Wu Zheng, but it is very long, about twenty centimeters.

From this look, you can tell that this weight is much heavier than you imagined. Undoubtedly, Wu Zheng was disappointed.

But in order not to dampen the enthusiasm of the craftsmen, Wu Zheng still smiled and encouraged him, and asked Qi Daokun: "How much does this grenade weigh? What is the size? What is the power after the test explosion?"

Qi Daokun replied: "The grenade weighs two and a half kilograms, the warhead weighs two and a half kilograms, the iron shell is half kilogram, the medicine is one and six kilograms, and the wooden handle is about four kilograms, and the wooden handle is used to ignite the flint. The size is, according to the measurement of the prince, the warhead is seven centimeters and the wooden handle is twenty centimeters, and the two centimeters that match the warhead and the wooden handle are 25 centimeters in total."

Wu Zheng thought, it was indeed so long, too heavy and too long, throwing it out was like a short branch rolling in the air. It was so hard, I guess it wouldn't be thrown far.

"What's the power after the test explosion?"

Chen Shoujie replied: "The power is much greater than estimated. Within three meters, fragments can penetrate armor, and both sheep on the left and right will die."

This is what satisfy Wu Zheng. As for the black gunpowder, Wu Zheng’s expectations are not that high. It is already good to have a killing range of one meter in radius.

Wu Zheng gently asked, "Is the combustion time of the fuse enough to ignite and throw it?"

Qi Daokun replied: "It has been enough after improvement. It is just a rope flint. Not every time the flint can ignite the flint, but it also needs to be improved. Therefore, in order to ensure ignition, two flints and two ropes are placed in the hole of the wooden handle."

Wu Zheng said: "Then try to explode and let me see the power of the explosion."

So, we came to the empty venue.

For safety reasons, no one was sent to make a trial vote.

Instead, fix the grenades on the ground, and then arrange livestock, armor and other test equipment.

Then use a long rope to lead it to thirty meters away and detonate.

The rope was pulled, and a light smoke began to emerge.

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

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

What makes black gunpowder inferior to yellow gunpowder is that the detonation speed of black gunpowder is slower than that of yellow gunpowder. Under normal circumstances, after ignition of the recharged medicine, there will be a delay of two or three seconds.
