Liuyun smiled and patted Craven Kabein's shoulder: "Originally, I was still worried about how to choose a vacation location, but now I don't have to worry about it." ”

"Well," Kraven Kabein sighed helplessly, thought for a moment, and added, "My father asked me to tell you that this summer camp will be dangerous. ”

As soon as he heard that there was danger, Liuyun knew that old Bister was going to be a "wolf grandfather", so he put out the thought of carefully packing his luggage, and just hastily put some daily necessities and a few daily clothes into his backpack and pulled it down.

Thanks to the blessing of the cosmic century, after tens of thousands of years, Liuyun re-experienced the opportunity to ride an old antique.

In the Age of Discovery, the space shuttle that could re-enter the atmosphere could basically only be seen in museums. Even the most remote planets travel in and out of the atmosphere by space elevators.

Before fusion reactors were put into practical use, electrically driven particle thrusters were only on paper. So, before the departure from the moon, a large bundle of booster rockets was installed on the butt of the shuttle.

Liuyun and Craven Kabein were on a chartered plane of the Bister Consortium, and among the passengers on board, there were a few casual "elementary school students" like Liuyun and them, and the others were civil servants in suits and leather shoes.

After the boarding prompt began to play, only a few passengers in the waiting hall began to move towards the gate as requested. Most of the rest of the passengers were saying goodbye to their friends and family who had come to see them off.

It was old Kabein who saw off Liuyun and Craven Kabein, and he didn't say much nonsense, but in front of his son, he explained a few words to Liuyun and asked him to take care of little Kabine, and then left in a hurry......

The big guys are always the last to come out.

By the time everyone had boarded the plane, the smiling Cartier Bister was late.

The business people in suits and leather shoes are very eye-catching, and the moment they saw the eldest young master, the complaints in their stomachs disappeared, and they were replaced with a smiling face in response......

Seeing the same mechanical smile, Cartier Bist's already bad mood was even worse......

Craven Kabin, who had been playing games since boarding the plane, felt that the atmosphere in the cabin was a little weird, and looked up to find that his old acquaintance, Cartier Bist, was walking this way with a black face.

"Katias, this way!"

Seeing that his acquaintance was calling him, Katias Bister's face became very embarrassed for a while, and after being entangled for a long time, he still walked to the seat next to Claven Kabein and sat down: "I'm sorry, Kraven, it's me who has caused you trouble. ”

"How is that possible?" Claven looked at the embarrassed Katias Bist, "A few days ago, I was beaten up by a female officer of the Federation, and I was looking for a place to exercise myself......"

As he spoke, Kraven turned his head to look at Liuyun who was reading a book: "Claude, this guy, can't find a suitable vacation spot, am I right, Claude?" ”

Liuyun put down the book in his hand and smiled at Cartier Bist: "The opportunity to go on vacation to Earth is rare, not to mention that the ticket is still free. ”

Cartier Bister was silent......

After the space shuttle left the port, it has been accelerating, and the slight push back feeling made Craven Kabein, who likes speed, very excited, and what made the young master Kabein even more excited was that the speed of the spacecraft was much faster than his iron armor.

"Claude," Claven Kabein turned his head to glance at Katias, who was closing his eyes and recuperating, then turned his head and looked cautiously at the flowing clouds, "when we get back from the moon, let's build a space shuttle too." ”

"Isn't it the kind with excellent acceleration performance and fast speed?"

Overjoyed, Craven Kabein nodded his head: "That's right! ”

"And then, the probability of you becoming space junk is an infinite way?" Liuyun gave the loss friend a roll of the eyes, "With the current level of power, it can only guarantee that your small space shuttle will fly out, not the return trip." ”

"Ah......" The huge gap in his heart made Craven Kabein a little depressed, "I thought it was ......"

"No," Craven Kabein looked around, leaned over to Liuyun, and asked in a low voice, "Isn't the Ark reactor ......guaranteed?"

Liuyun gave Kleven Kabein a second tofu eye: "Young Master, you don't know how expensive firewood and rice are at home."

The Ark nuclear reactor has indeed achieved a fusion reaction, but the utilization rate of nuclear fuel is pitifully low, and the most important thing is that the metal palladium that controls the flow of tritium gas is extremely expensive: the entire reactor, the sponge palladium alone accounts for more than 90% of the entire reactor cost.

A large part of the reason why Marvel can afford to use palladium is that the industry has acquired an entire palladium metal industry chain in order to control the cost of Jericho missiles......

Although it is now the age of the universe, the metal palladium is still a precious metal, the production is very low, and the price is more than a thousand times that of gold.

After listening to Liuyun's explanation, Kraven Kabine's head suddenly drooped.

Liuyun shook his head helplessly: Old Kabein had already tried, if the Ark nuclear reactor could be enlarged, Anaheim would be able to set up a power branch half a year ago.

Although he has the technology of a nuclear fusion reactor in his hand, when the prospect is not very clear, Liuyun does not want to take it out, and he cheapens the Federation that already has a big tail.

Although he already knew that there was no room for upgrading the Ark reactor, Kleven Kabein still did not give up: the feeling of being able to gallop through the universe was too tempting......

Still, think about it.

Kraven didn't give up, and quickly used his brain, hoping for a better solution. Then Craven thought of the model of the Minovsky fusion reactor that he had seen from his father......

"Claude, have you heard of the Minovsky fusion reactor?"

Liuyun smiled and looked up at Kraven who was full of anticipation: "You are looking for the wrong person, the only Minovsky nuclear fusion reactor in the Federation, now in Oak Ridge, is still a non-display piece." ”

"Well," Kraven Kabein frowned, thought for a moment, and tentatively asked Liuyun, "If, I mean, if we get our hands on that prototype, can you crack it?" ”

"It depends on whether Minovsky deliberately set a limit on that prototype that is difficult to break!"

Craven Kabein nodded thoughtfully, and turned his head to look at Cartier Bist, who was recuperating with his eyes closed: With the wealth of the eldest young master Jia, there should be a chance to get that thing......

It took several hours for the shuttle to reach the Earth's periphery, surrounded by space junk, and then began to slow down......

The passengers on the space shuttle suddenly turned ugly when they saw the earth, which was already close at hand. Even Master Kabein, who has always liked to be nervous and exciting, clutched the handrail and stared straight at the portable armor on the luggage rack above his head......

The speed of the space shuttle was getting slower and slower, and Liuyun, who was reading a book, heard the clanging knock outside the window, raised his head, turned his head to look out the window......

What a big dump!

It has been more than 170 years since the first satellite was launched into the sky, and although there are special public welfare organizations responsible for cleaning up space junk, it is a drop in the bucket compared to the huge space junk belt......
