There is only a pile of gravel lying on the bare island. The beaches made of golden sand and gravel wind into the sea, alternate with beautiful green and blue coastal scenery. In this island with only bare reefs and gravel, it is the southeastern island of Xinguo, located on the north side of the equatorial line.

The flat land and wide sandbars are its only advantages. The factory building standing in the middle of the island has not been painted yet, and it was obviously only built not long ago.

At this moment, Jiang Chen's private yacht was docked at the simple Fisherman's Wharf located on the edge of the island.

This pier originally belonged to a fisherman in the New Kingdom. The honest fisherman didn't even know that the regime had changed. It was not until the Star Ring Trading Company showed him the real estate certificate that he understood the fact that he illegally occupied private land.

However, Jiang Chen did not make things difficult for him and bought the simple wooden pier and nearby fishing ground from him for $10,000.

So this pier became the only building on this deserted island except for the factory in the center of the island.

"Is this our company's residence?" Looking at the bare factory, Kelwin's mouth twitched.

He felt he was being cheated in contract.

This is not what it is to work, it is like being exiled.

"Of course not. Before the office building is built, you will temporarily work in the Star Ring Trade Headquarters building on Koro Island. Of course, your main task is to learn the information I provide to you."

"Ahh? The information you provided to us." Kerrwen raised his eyebrows, obviously disdaining Jiang Chen's statement.

Jiang Chen just smiled slightly and did not explain anything about Kerwin's conceit.

"It's already here, let's get off the boat."

Because there is no vegetation, the soil here has been exposed to sunlight for many years, making it look fine and hot. Stepping on the sand outside the pier, Aisha, wearing thin-soled sandals, felt obviously uncomfortable. However, she did not show the discomfort, but just wrinkled her beauty slightly.

However, this subtle change did not escape Jiang Chen's eyes.

"Or why don't you go to the boat to rest for a while? Anyway, the island is very safe, and you don't need to worry about something happening to me." Jiang Chen said considerately in her ear when he noticed Aisha's discomfort.

Aisha's cheeks were red when she was seen through.

After some hesitation, she did not show off her strength anymore, nodded and accepted Jiang Chen's care frankly.

"Um."

Looking at Aisha who was returning to the boat, Jiang Chen smiled. He turned around and greeted Kerwin, and walked with him to the warehouse in the center of the island.

After pushing open the door of the warehouse, Jiang Chen drove away the ash in front of his nose and walked to the edge of the warehouse to open the metal blinds.

When the sun shone into the room, Kerwin noticed the rocket engine placed on a large square iron frame.

The cylindrical body and bowl-shaped tail end are slightly smaller than the spae-x Molin engine, making people wonder whether it can bear a rocket that is more than ten times its size.

"What is this?" Kerwin walked forward and stretched out his finger and tapped it on it.

"The RM-320 rocket engine is the technology I'm going to show you." As he said that, Jiang Chen handed the tablet computer with technical parameters and 3D concept diagram to his hand.

This is the rocket engine that Jiang Lin showed to Jiang Chen at the Institute of Aerospace Science and Technology last time, and it is also the normal size version of the Beifeng-76 (pseudo) ballistic missile engine deployed by NAC in Shenxiang Town.

From a screw to a wire, this engine is completely made of 3D printing technology and costs 30,000 credit points. The propellant used by the rocket is made by Lin Ling, and the cost is about 1,000 credit points per ton. However, because the materials can be shipped from the present world, the actual cost of these things may be cheaper.

Due to the emergence of space elevators, the working fluid-propelled rocket technology for aerospace uses was eliminated at the end of the 21st century. Therefore, this RM-320 rocket engine can be regarded as the most advanced manned space rocket in the wasteland.

The engine shell using advanced materials can withstand high temperatures of 10,000 degrees, and the combustion chamber can withstand pressures up to 500 atmospheres. The most important thing is that the rocket built with this engine can even reach a terrifying 1:300! It is undoubtedly a complete 1:150 for the Spae-x company Falcon Rockets!

"It's simply nonsense. Such an engine is simply impossible to achieve with current technology. What about the materials? Ordinary engines cannot withstand this pressure and high temperature... How is this possible... Wait, what's the chemical formula of this rocket propellant?"

Kerwen frowned, and the expression on his face kept changing. Sometimes he shook his head, sometimes he was surprised, sometimes he was glaring with his eyes...

Finally, his expression was frozen in his dumbfoundedness.

"This is ridiculous, no...this is too genius." murmured to himself. Kerrwin's hand holding the tablet kept trembling, "This is definitely possible, no, it is only theoretically possible... But if it is achieved, the Spae-x's Falcon Rockets will become a joke. But this is ridiculous..."

Suddenly, he looked at Jiang Chen and applied to grab Jiang Chen's shoulder fanatically.

"Please, can you recommend the designer of this rocket engine to me? He is simply a genius."

"I will convey your praise for you, but I'm sorry, I can't introduce him to you for the time being." Jiang Chen shook his head and said.

"Why! Are you worried about me leaking the secret? Don't worry, I will sign the confidentiality agreement no matter how harsh it is. Please! I hope to ask him for advice on many questions in person." Kelwin said excitedly.

At this moment, there was no longer the contempt he had when he had just got off the boat.

The design concept and technological innovation of this rocket engine deeply impressed him and shattered his pride in technology.

"No, please don't get me wrong. I trust your character very much. But the designer of this rocket is currently studying a project about the space shuttle and does not want to be disturbed by anyone... Well, you can understand that he is in a state of retreat. I promise that if you have the chance, I will definitely recommend him to you. As for your question, I will provide you with a detailed rocket design drawing, and you should be able to get the answer from it. If this still cannot solve your confusion, I can convey your problem for you." Jiang Chen said casually.

Just kidding, the designer of this rocket has not been born yet, where can I find it for you? In the future, when the jump bracelet can take people through time, just pull that kid Jiang Lin over to count.

"Wait, I have another question. Such a rocket engine cannot be completed with the industrial foundation of the new country... With the manufacturing capacity of the United States, it is also difficult. Where did you build it?"

"It's here." Jiang Chen smiled.

"That's it?" Kelvin was stunned.

"You must have heard of 3D printing technology. This rocket engine is made of industrial-grade 3D printers."

Can you print such high-strength materials with a 3D printer? And what is the new term for "industrial-grade 3D printer"?

Kerwin was completely shocked by the new technology and forgot his words for a moment.

Seeing this, Jiang Chen coughed gently, interrupting his thoughts.

"Okay, now that you have finished watching it. Then Mr. Kerrwin, our trip today is over...it's time to go back."

"No! Let me stay here! Please!" Kelvin gently stroked the shell of the engine, and his passionate expression and movement seemed to be stroking, touching his lover's skin.

Although I am very satisfied with the enthusiastic attitude of the scientists under my command towards technology, Jiang Chen always feels that this action is a bit disgusting no matter how you look at it...

"Mr. Kerrwin, I have to remind you that there is nothing here. And the Starring Trade Headquarters building has air conditioning and endless coffee, as well as a complete design for this rocket engine. Even if you are working there"

Kerwin interrupted Jiang Chen in a rude way and said without hesitation.

"Just give me a tent, I'll sleep here! There are those documents, please bring me over, please!"

Jiang Chen suppressed his smile and nodded.
Chapter completed!
