The mage in the late Qing Dynasty

Therefore, when Zhao Chuanxin and Miao Cuihua appeared on the deck, Rachel Kervis's face was still red.

She didn't even dare to look at the two of them, as if she took one more look, she would be seen through.

Zhao Chuanxin didn't pay much attention at first, but Rachel Kevis always dodged and evaded, so he asked curiously: "Is it because of the strong sea wind that I lost my eyesight?"

Rachel Kervis felt very excited: "No, no..."

They are all people who have been through this before, so they are no strangers to this kind of thing.

But the protagonist is Zhao Chuanxin.

At this time, Samuel Goldberg and Benjamin Goldberg, who were unaware of the situation, were having a cane-making conversation.

Samuel Goldberg said: "Benjamin, you should give me the money. You know what dad is capable of. When you make money, I can buy you a car or a house if you want."

Benjamin Goldberg said: "It's the same with me. I have a stronger ability to make money. When I earn more, Dad, I will buy you a house and a yacht."

The money won’t be given to you anyway.

Jiang Bo grinned when he heard this: These two men are more bragging than the other.

Zhao Chuanxin laughed and said, "You two are drawing cakes against each other to see who can be beaten to death!"

Father and son: "..."

Benjamin Goldberg took out a book and asked Zhao Chuanxin: "Master, look, this character is very rare. What do you mean?"

Zhao Chuanxin looked at her and said, "It's my concubine, read bi."

"What does master mean?"

"Master means master. My father dies as a test, my mother dies as a heir, and it's best for master to live forever."

"..." Benjamin Goldberg nodded: "Master, if I die, how will I write? Should I write about my beloved disciple Benjamin?"

"No." Zhao Chuanxin shook his head: "If you die, write a letter of great kindness!"

Miao Cuihua couldn't help laughing: "It's not formal."

Zhao Chuanxin smiled: "Evil disciple, don't read too much, otherwise your brain stem will get knotted."

Samuel Goldberg couldn't understand Chinese and was discussing the issue of clothes with Jiang Bo.

"What do you think of my custom-made suit?" Samuel Goldberg asked irritably.

He spent a lot of money to customize this.

Jiang Bo looked up and down: "It's not very good."

Samuel Goldberg's face froze.

Zhao Chuanxin knew that this boy had something in his stomach, so he asked, "What do you think of mine?"

Jiang Bo clicked his tongue and said: "Shockingly ugly, this appearance will cause your dignity to be lost..."

"Bleach!" Zhao Chuanxin slapped him on the head: "You're so stupid. You dare to say such things to your boss. It's really nonsense."

Jiang Bo instinctively rubbed his neck: "I'm not wrong. Of all the people present, only Sister Hua has the best taste in dressing."

Huh?

Zhao Chuanxin asked, is it true?

He always felt that his clothes were good, but he knew that Miao Cuihua had a unique talent in aesthetics.

Since there is an anchor point, it means that Jiang Bo is not just talking nonsense and deliberately suppressing him.

He said: "Since you don't distinguish between superior and inferior, I will fine you to customize a set of clothes for me, just to test your craftsmanship."

Jiang Bo spread his hands: "I have tools, but no fabric."

"I've prepared it for you, go to the cabin to get it."

Jiang Bo: "..."

There was nothing to do on the boat, so Zhao Chuanxin did what he said.

When Jiang Bo came to the cargo hold, he found that there were various fabrics piled inside, including tweed, fine wool and silk blends, worsted wool, and canvas...

He was shocked and said: "Zhao, are you going to take it back and sell it?"

"No." Zhao Chuanxin leaned against the hatch: "These are all prepared for me and my family and friends. The rest will be used to open a tailor shop."

Jiang Bo picked and selected, rolled the cloth out, took out the tools, and started to measure Zhao Chuanxin on the deck under the bright natural light.

Samuel Goldberg said shyly, "Make me a set too, by the way."

Jiang Bo rolled his eyes: "Why? He is my boss. You spend money to do it, and the fabric and handwork fees cannot be less."

Zhao Chuanxin used his body to block his view and secretly gave him a thumbs up.

Look, this is a solid partner.

Jiang Bo was even more proud when he saw that Zhao Chuanxin could praise others, which was rare.

Samuel Goldberg muttered dissatisfiedly: "I don't know your craft yet, let's take a look."

What he said was correct.

While measuring Zhao Chuan's salary, Jiang Bo said: "Generally speaking, there are only three styles of traditional suits, British, American and Italian. If I go to work in Asia, I will definitely have suits tailor-made for Asians and suitable for Asian figures."

Zhao Chuanxin felt that he had found the right person.

He had seen photos of Sun Gongwu. His Chinese tunic suit was modified with good intentions, but the rotator cuffs were not properly treated, causing the sleeves to turn outwards. Then there is not enough margin, causing the hem to diverge slightly, which is too tight.

So just copying a lot of things won’t work.

After measuring, Jiang Bo hurried back to his cabin with the tools.

Benjamin Goldberg said: "Master, let's study RPG."

Zhao Chuanxin had just finished working, and he wanted to get a deck chair, cover himself with a blanket, rest on the deck for a while, and read through his diary.

Because "I" will soon return to the city-state.

So he made an excuse: "Aren't you cold?"

Benjamin Goldberg flexed his biceps: "Ever since I practiced that magical skill, I have been immune to the cold and heat!"

Zhao Chuanxin saw that his face was indeed flushed and he looked very healthy.

On the other hand, Samuel Goldberg and Rachel Kravis looked pale.

"Okay then..." Zhao Chuanxin reluctantly said.

The rocket launcher itself has a very simple structure, consisting of a smooth-bore steel tube, a few stamped parts, and a wooden shell for heat insulation.

What is more difficult is the human-machine function of rockets and launch tubes.

This weapon must be versatile.

One day in the future, Zhao Chuanxin will use it to deal with the first- and second-generation tanks that invade Maozi.

The master and apprentice quickly drew the design of the launch tube.

"Master, let's build the launcher first?" Benjamin Goldberg asked.

"No." After all, Zhao Chuanxin knew that rockets were the key point. "First design rockets to deal with various armored units and make them together."

Benjamin Goldberg had no idea: "Master, are we going to wear armor?"

Zhao Chuanxin shook his head: "It's not armor-piercing, it's armor-breaking. Just imagine, the conical head of a rocket hits the steel. It's not a breakdown, it's just a simple break. It needs to eject the metal bullet stream, accompanied by high temperature. In this way, The people and equipment inside the armored unit suffered."

Benjamin Goldberg thought for a while: "Then after the warhead hits the object, the backward force is very small, but it has to push the gunpowder forward. So we should design a conical cavity."

Zhao Chuanxin added: "When rockets fly, they also need to remain stable."

Benjamin Goldberg immediately said: "The smooth-bore launch tube needs to fly smoothly, so adding a tail fin to the rocket is the right choice. The rocket will rotate. Finally, a windward impeller with a relatively large pitch deflection is designed. Launch. The barrel is very thin, so the tail has to be gradually opened during flight. However, it cannot be launched close to the ground, or it cannot be launched in jungles or places with wires, because the tail will be entangled in wires and branches. It is really distressing, and there is no suitable one. solution."

Zhao Chuanxin's eyes lit up: "Yes, that's it. You don't have to think about solving all the problems. Even a large-caliber rifle will be affected by wind resistance, not to mention such a large rocket?"

The cross-sectional drawing of the rocket appears on the paper.

There is a cone-shaped head in front, with a cone-shaped cavity at the front end and a half-bowl shape in the middle. There is no gunpowder in it and it is completely empty.

Zhao Chuanxin frowned and looked at it.

With his limited knowledge and imagination, he could not understand the principle of this cavity at all.

The apprentice had to explain to him: "Master, this rocket should not rely on the power of a large amount of explosives to break armor. We need to give the rocket a space to fully burn. The energy generated will be rapidly supercharged in this small space." , concentrating the force on one point to break the armor, the hot metal flow will penetrate the steel plate and enter the interior of the vehicle body, thereby damaging the personnel and equipment inside."

Zhao Chuanxin roughly understood.

When the rocket flies, gunpowder is fired backward from the inclined nozzle to ensure rotation.

But when it hits an obstacle and the fuse is lit, it will spray forward instead.

This is the secret why RPG rockets are so slow and have such a short range, yet they can penetrate armored tanks.

But a new problem arises here.

Zhao Chuanxin said: "How to design the impact fuse?"

Benjamin Goldberg thought for a while: "The only way is through experimentation."

The master and apprentice used a cone-shaped round head, put a small amount of gunpowder into it, and conducted a free fall experiment on the deck.

But I found that if it was just armor-piercing bullets, the classic fuze was acceptable.

But when it comes to high-explosive bombs, Benjamin Goldberg said: "It would be great if there was electricity, and the explosion could be triggered by electricity."

If Nikola Tesla’s imagination is unconstrained and contains many idealistic things, then Benjamin Goldberg needs to be more based on his own cognition.

As far as he knew, apart from his master's Thor's Hammer bracelet, there seemed to be nothing that could generate electrical energy in extremely small units.

Zhao Chuanxin suddenly thought of something - the electronics of the lighter.

But he couldn't describe the principle in detail. He could only say: "Silicon dioxide crystal has a piezoelectric effect. When the crystal is under pressure, voltage will be generated on both sides. The greater the pressure, the higher the voltage, but the electricity is not large. Connect a section A wire can ignite a fire."

Benjamin Goldberg clapped his hands: "Although I have never heard of it, if it is true and a very small volume can produce ignition, then this problem will be completely solved."

Zhao Chuanxin nodded: "When we get ashore, call Nicholas and ask him for advice."

Benjamin Goldberg looked dissatisfied: "Why use him? I can complete the experiment myself."

"Have ambition." Zhao Chuanxin was greatly relieved. "You should also have the ability to conduct independent experiments."

"Of course." Benjamin Goldberg held his head high: "But I'm still used to the feeling of Master turning my ideas into reality quickly."

"..."

Hard-working brains and lazy limbs, right?

It is easy to build rockets on a ship, but it is not easy to test them on a ship.

Zhao Chuanxin was not in a hurry anymore.

He waved his hand and said, "You can go back and perfect it again. Master is going to meditate on the recliner now."

Saying that, without waiting for his apprentice's reaction, he immediately took out the recliner, set up the formation, and took out the "Old God Codex"...
