Qingyi Villa, in another open-air hot spring near the lake.

Zhao Hao, Li Chengen, and Zhao Shizhen, who came from the research institute after hearing the news, were also in a waste.

The scene here is much more bold. Lee Chengen and Xiwa were drinking three white wine while dancing naked.

It was mainly Lee Seung-en who boasted about his numerous achievements in hunting in Nanhaizi.

According to the little lord, his results include more than 200 wolves, more than 100 bears, thirty tigers, six elephants, and more than 1,000 rabbits...

Xiwa believed this deeply, shouting that the little lord was invincible, and kept asking Li Chengen, is the elephant's nose really that long?

No wonder Lee Cheng-en likes to play with him so much.

Zhao Hao and Zhao Shizhen sat on the other side of the bathtub, drinking Biluochun while whispering serious matters.

There is no way, the inventors are all workaholics, and Zhao Shizhen came to Mr. Zhao to report on his job.

"Uncle, the Longqing style has been finalized, and the paper-shell fixed loading has been developed." Zhao Shizhen said as if he was magical, and handed Zhao Hao a candy-like bullet.

Zhao Hao widened his eyes and looked at Zhao Shizhen up and down. He saw that the boy was naked and didn't know where he took out the bullet.

Mr. Zhao was somewhat suspicious and used bamboo tweezers to hold a teacup, took the paper-shell bullet, and looked at it through the light.

I saw it was about the same length as a human index finger, and it was wrapped in paper shells, one end pointed and the other end thick.

"When using it, just use your teeth to bite the bullet tip and pour the gunpowder inside into the fire pool. The projectile is in the middle of the paper shell, blocking the remaining gunpowder and not pouring out." Zhao Shizhen explained like a treasure:

"Then close the fire door, stuff the remaining gunpowder and projectiles into the barrel with a strip. We have tried it and can use this kind of bullet to fire three rounds in one minute."

The institute has long used Thai clocks from Macau, so naturally it has the concept of minutes.

"That's not bad." Zhao Hao thought for a moment. If this gun was in the hands of the Qi family, it would have been able to fire a sufficiently dense rain of bullets. Even if it was facing the cavalry's charge, it would no longer be weak.

‘Pairing the bayonet with it can basically meet the requirements of Zhang’s idol.’ Zhao Hao thought to himself that in this way, he would not have to worry about the meeting gift when he went to Beijing to see him next year.

"By the way, uncle, my mother-in-law gun is installed in the back," Seeing his uncle's approval, Zhao Shizhen plucked up his courage and said, "I'll name it Xunlei gun."

"Thunder gun." Hearing this name that is of great significance to the otaku, Zhao Hao silently took a sip of tea and praised it for a long time: "A good name, but unfortunately there is no magnetic chain, so he still can't rush up."

"Uh, magnetic chain?" Zhao Shizhen asked curiously: "What device is that?"

"Please I didn't say it." Mr. Zhao shook his head. Hey, when the teachers were not born, Thunder had nothing to do with it.

"..." Fortunately, Zhao Shizhen often heard some crazy new words from his uncle's mouth, and he was no longer surprised. He turned his attention back to the Thunder gun he was thinking about, and said: "My nephew fired a sample gun and tried it. It was indeed as my uncle said, the air leak was so bad that the bullet could not take thirty steps."

"Of course." Zhao Hao said lightly: "The superiority of installing a gun afterwards is great, but unfortunately this one is sentenced to death."

"No, uncle, I thought of a solution." Zhao Shizhen sat upright and said excitedly: "It's what my uncle once said - to do a miracle with great force!"

"Oh?" Mr. Zhao looked suffocated and looked awe-inspiring, thinking that he was a man who was determined to capture Ashi alive. Is he really going to create a miracle?

"Since the air leakage cannot be solved, I will increase the power of gunpowder, which can also drive the bullets far away!" The gun-making maniac shouted: "So I increased the charge!"

"What then?" Zhao Hao looked expectant.

"Then it exploded..." Zhao Shizhen collapsed and said, "Fortunately, my nephew was guarding against this move, using the extension trigger, otherwise he would have to blow up his fingers."

"..." A bright tea soup flowed down the corner of Mr. Zhao's mouth.

"So uncle, there is only one last solution for the present plan!" Zhao Shizhen looked at Zhao Hao with bright eyes, and said, "You said that nitroscopic cotton last time..."

"You are stupid, aren't you? Even black gunpowder can explode, but will the nitroscopic cotton not explode?" Zhao Hao slapped his head hard. "You'd better think of a way first and get the steelmaking process up!"

"My nephew has guessed that even if it is changed to a steel barrel, if you want to make a Thunder gun two hundred steps, you have to make the barrel as thick as your forearm." Zhao Shizhen still refused to give up and said, "Is it a gun or a cannon? So uncle, he still needs more powerful gunpowder..."

"No, absolutely not. That thing is too unstable, and you'll be killed..." Zhao Hao shook his head flatly when he heard this. He wanted to 'who made a gun for me', but he felt it was too unkind, so he changed his words: "I will feel distressed."

"Uncle..." The orphan Zhao Shizhen was immediately moved and tears were filled with tears. He looked at his uncle who was as old as him and said, "Just once, promise me once."

"If you say no, you won't do it." Zhao Hao knocked his head hard and said in a deep voice:

"I have told you many times that the reason why I didn't pass it on to the course "Chemistry" is because you are too impatient and too brave! If you talk nonsense to me again, go to Kunshan honestly and don't think about going back to the research institute!"

"Oh, I know, uncle..." Zhao Shizhen immediately looked like a deflated ball. There was nothing in the world that could threaten him more than this.

Seeing that he was hit hard, Zhao Hao sighed and said:

"You have to learn to be patient. This is how science comes about. The emergence of an invention can be applied in practice. It requires a long trial and error. You must do it step by step and avoid being impatient."

"I understand uncle." Zhao Shizhen nodded quickly after receiving the teachings.

In fact, Zhao Hao's words are half true and half false. Half true is that this is a common law that lies in the relationship between invention and application. It does take a long time to test the nitroscopic cotton to eventually turn into smokeless powder.

Half of the falsehood is that Zhao Hao knows how to prepare smokeless gunpowder, so there is basically no need to try and make mistakes repeatedly.

First soak the cotton wool with sulfuric acid and nitric acid mixture, then take out the cotton and wash it and dry it to make the nitrocellulose cotton.

Then use sulfuric acid and alcohol to prepare diethyl ether, dissolve the nitrosilicate cotton with a mixture of diethyl ether and alcohol, and then add camphor as a stabilizer to make a solid. The solid is tableted and divided into particles, and then it is made into smokeless gunpowder with two to three times the power of black gunpowder.

OK, let alone ether, Zhao Hao hasn't even started preparing sulfuric acid and nitric acid yet.

But Xishan Island has found pyrite. With pyrite, will sulfuric acid be far away? With sulfuric acid, will nitric acid be far away?

Zhao Hao is confident that he will overcome all difficulties within three to four years and meet all the conditions for preparing smokeless gunpowder.

Moreover, Zhao Shizhen's genius intuition is correct. It was the birth of smokeless gunpowder that replaced the front-loading gun.

But the problem is that Mr. Zhao has made up his mind and will not tell the disciples the formula of smokeless powder even if all the conditions have been met.
