The bare island lies only a pile of gravel, and the sandy beach of golden sand winds its way into the sea, alternating between green and blue coastal scenery. The island is the southeastern part of the new country, with only bare reefs and rocks, on the north side of the equator line.

The flat land and wide sandbar are its only strengths, and the factory building that stands in the middle of the island has not yet been painted, apparently built only recently.

At this moment, Jiang Chen's private yacht docked at the humble fisherman's wharf located on the edge of the island.

The wharf originally belonged to a fisherman in the New Kingdom, and the honest fisherman didn't even know that the regime had changed, and it wasn't until someone from the Transwarp Trading Company showed him the real estate certificate that he realized that he was illegally occupying private land.

However, Jiang Chen did not embarrass him, and bought the humble wooden dock and the nearby fishing ground from him for $10,000.

As a result, this wharf has become the only building on this desert island, except for the factory building in the center of the island.

"This is where our company is located?" the corners of Kirwin's mouth twitched as he looked at the bare factory.

He felt like he had been cheated by a contract.

Where is this to go to work, it's like being exiled.

"Of course not, until the office building is built, you will be temporarily working in the Star Warp Trade Headquarters building on the island of Koro. Of course, your main task is to study the information I have provided you. ”

"Aha? Kerwin raised his eyebrows, obviously dismissive of Jiang Chen's statement.

Regarding Kerwin's conceit, Jiang Chen only smiled slightly. No explanation is given.

"It's here, let's get off the boat. ”

Because there is no vegetation, the soil is exposed to sunlight all year round. It appears finely crumbled and piping hot. Stepping on the sand outside the dock, Aisha, who was wearing small sandals with thin soles, was visibly uncomfortable. However, she didn't show her discomfort, but only slightly wrinkled her beauty.

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

"Why don't you go to the boat and rest for a while? It's safe on this island anyway, and you don't need to worry about what happens to me. Noticing Aisha's discomfort, Jiang Chen said thoughtfully in her ear.

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

After some hesitation, she didn't give up her head anymore and nodded. Frankly accepted Jiang Chen's concern.

"Hmm. ”

Looking at Aisha who was returning to the ship, Jiang Chen smiled and turned to greet Kirwin. Walk with him to the warehouse in the middle of the island.

Pushing open the door of the warehouse, Jiang Chen chased away the ash in front of his nose, walked to the edge of the warehouse and opened the metal shutters.

As sunlight poured inside, Kirwin noticed the rocket engine on a large square iron frame.

Cylindrical body. Bowl-shaped tail end. Slightly smaller than Space-X's Merlin engine, one wonders if it can afford a rocket more than a dozen times its size.

"What is this?" said Kirwin, holding out his finger and tapping on it.

"The RM-320 rocket engine, that is, the technology I am going to show you. As he spoke, Jiang Chen handed the tablet containing technical parameters and 3D concept drawings 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-sized version of the Beifeng-76 (pseudo) ballistic missile engine deployed by NAC in Shenxiang Town.

From a screw to a wire, the engine is entirely 3D printed and costs 30,000 credits. The propellant used in the rocket was made by Lin Ling. The cost is about 1,000 credits per ton. However, since the materials can be shipped from the present world, the actual cost of these things may be cheaper.

Because of the advent of the space elevator. Working fluid propulsion rocket technology for space applications was phased out at the end of the 21st century. So this RM-320 rocket engine can be regarded as the most advanced manned space rocket in the wasteland in a sense.

The engine shell using advanced materials is capable of withstanding temperatures of up to 10,000 degrees Celsius, and the combustion chamber can withstand pressures of up to 500 atmospheres. The most important thing is that the thrust ratio of the rocket built by this engine can even reach a terrifying 1:300! It is undoubtedly 1:150 of the Falcon rocket of Space-X!

"It's just nonsense, such an engine is impossible with the current technology, and what about the materials? It is impossible for an ordinary engine to withstand such pressure and high temperatures...... How is this possible...... Wait, what exactly is the chemical formula of this rocket propellant. ”

Kerrwin's brow furrowed, and the expression on his face kept changing. Sometimes shaking his head, sometimes surprised, sometimes staring at his eyes......

Eventually, his expression froze on his jaw-dropping.

"It's ridiculous, no...... It's genius. Muttering to himself, Kerwin's hand holding the tablet trembled, "This one will definitely work, no, only theoretically...... But if it happens, the Falcon rocket of Space-X will become a joke. But that's ridiculous......"

Suddenly, he looked at Jiang Chen and grabbed Jiang Chen's shoulder feverishly.

"Please, can you introduce me to the designer of this rocket engine? He's a genius. ”

"I'll pass on your compliments on your behalf, but I'm sorry I can't introduce him to you just yet. Jiang Chen shook his head and said.

"Why! Are you worried that I'm leaking secrets? Don't worry, no matter how harsh the confidentiality agreement is, I'll sign it, please! I want to ask him a lot of questions in person. Kirwyn said excitedly.

At this moment, his face no longer had the contempt he had when he first got off the ship.

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 have a lot of trust in your character. It's just that the designers of this rocket are currently working on a project about the space shuttle and don't want to be disturbed by anyone...... Well, you can understand that he is in retreat. I promise to introduce him to you if I have the chance. As for your question, I will provide you with a detailed drawing of the rocket design, from which you should be able to get the answer. If that still doesn't solve your confusion, I can relay your questions on your behalf. Jiang Chen said casually.

Just kidding, the designer of this rocket hasn't been born yet, where can I find it for you? In the future, when the jump bracelet can take people through, just pull Jiang Lin's kid over to fill the number.

"Wait, I have one more question, such a rocket engine is impossible to complete with the industrial base of the new country...... With the manufacturing capacity of the United States, it is enough, where did you make it from-"

"This is it. Jiang Chen smiled.

"Is this it?" said Kirwin.

"You've probably heard of 3D printing. This rocket engine is made by an industrial-grade 3D printer. ”

With a 3D printer, can you print such a high-strength material? And the "industrial-grade 3D printer". What is a new term?

Kirwin was so caught up in the shock of the new technology that he forgot his words for a while.

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

"Okay, now that you've finished reading. So Mr. Kirwin, our trip for today is over...... It's time to go back. ”

"No, let me stay here! please!" Kerwin caressed the shell of the engine, his frenzied expression and movements, as if he were caressing and touching his lover's skin.

Although he was very satisfied with the fanatical attitude of his scientists towards technology, Jiang Chen always felt that this action was a little inexplicably disgusting no matter how he looked at it......

"Mr. Kirwyn, I have to remind you that there is nothing here. The Transwarp Trade Headquarters building has air conditioning and endless coffee, as well as complete blueprints for the rocket engine. Even if you're working there—"

Kerrwin interrupted Jiang Chen's words very rudely and said unceremoniously.

"Just give me a tent, I'll sleep here! And those papers, bring them for me, please!"

Jiang Chen held back a smile and nodded.

"Since you insist. (To be continued.) )
