Johnson looked at what Lu Yuan pointed seriously and saw that the three robots had different tools on their hands. They collaborated with each other to assemble and polish an object in a pile of parts. This thing looked a bit like a large scooter, all white, and something similar to a jet engine.

He watched the robot assembled for a long time, but he could not tell what it was.

I could only tentatively speak: "Is this a? small rocket?"

Su Mei laughed out loud, then covered her mouth and said, "Look, I also said it looks quite like a Rocket, right?"

Lu Yuan walked over, shook his head, and snapped his fingers at the robot.

It seemed that he had received Lu Yuan's instructions, so the robots began to simply assemble the shell regardless of the complex parts inside the object. At this time, Johnson roughly realized that it was basically like a large sled board with a smooth panel at the bottom and a single person can stand on it. The panel seemed to be equipped with a relatively complex engine device that could spray propelling gas backwards.

"Is this a rocket sled?" Johnson couldn't help asking again.

"This time I got it right." Lu Yuan nodded and said, "Strictly speaking, this is a nuclear-powered jet sled."

But when Lu Yuan said this, Johnson became even more confused: "Nuclear-powered? Jet? Sled?"

He said these isolated words in succession.

"Why do you need to make a sled like this?"

Lu Yuan looked at Johnson and explained softly: "Because, I need a single-person vehicle that can drive in a vacuum-like environment of minus 200 degrees Celsius at a speed of 300 kilometers per hour."

The boy's voice was calm, but Johnson was confused when he heard it: "There is no need for such a vehicle on Earth, right? Even for extraterrestrial planet exploration, the exploration vehicle required will not have too high speed to facilitate the control of ground personnel."

On the side, Su Mei pursed her lips and stood up and explained: "I wonder if Dr. Johnson has personally experienced this game that will not come tomorrow?"

Johnson nodded slightly: "I only experienced it once a while ago."

He then reacted: "You mean?"

Su Mei nodded: "Yes, this is a vehicle that you want to use in a game that will not come tomorrow, so since we have the conditions, we will create a prototype in advance to see the effect."

Johnson knew that tomorrow would not come to the world, the world will be decades after the sun was extinguished, where the ice and snow were frozen, and the temperature was almost close to absolute zero, which was an extreme world that could not support the survival of humans or even any living creatures.

But even in such a world, why do you need to make such a vehicle?

Johnson continued to express his doubts.

"Because one of the difficulties we have in the game now is how to use the conditions at hand to travel through thousands or even tens of thousands of kilometers of snowfields and finally head to a distant base." Lu Yuan replied: "We have been thinking for a long time and believe that making a sled is the most suitable tool."

In fact, when Su Mei was playing tomorrow, she used sleds to explore and search the city in Binhai City. However, the sleds at that time were just pure sleds, and they still needed sled poles to accelerate the change of direction.

But if the big guy present in front of Johnson, if the driving force is the propulsion gas emitted from the nuclear-powered engine, then Johnson is not surprised to increase the speed to hundreds of kilometers per hour, but what about operations such as slowing down and changing direction?

Johnson continued to ask.

"Well, the design will eventually be a variable-direction vector nozzle to complete the operation of changing directions. In this way, this individual nuclear-powered jet sled can increase the maximum speed to 500 kilometers per hour, which is more than the high-speed rail currently running on the ground." Lu Yuan said.

"Okay, I understand the truth." Johnson nodded: "But in this case, isn't it easier for you to simply make it in the game?"

"After all, I have heard that you have simulated the operation of nuclear fusion in the game. I heard that there is a saying in the East that governing a big country is like cooking a small fresh food. Then you have even created a feast of a nuclear fusion device. You won't be able to handle this little thing."

"That's right, I can't handle it." Lu Yuan shook his head and said: "When testing nuclear fusion, I used plug-ins with top-level permissions, but now it needs to be performed in the game's built-in rules."

"Just like the game cracking work you are doing and the observation actions in the game, not to mention the former, but to the latter, the reconnaissance of the Mechanical Pioneer Base will only last less than two days, and it cannot promote the progress of the game's plot. Once promoted, it will cause the evolution of the plot and lose the opportunity to observe. Even saying that attracting the king's attention will lead to the failure of the game itself."

The road is long and slowly and well-organized, saying: "The same is true now. What we have to do is to defeat thousands of kilometers of frost and snowfields in multiplayer mode. The manpower and material resources of each scattered refuge are far inferior to our real world. Otherwise, I could directly build a comfortable and stable giant vehicle such as a polar track car in the game, rather than a simple nuclear-powered jet sled to travel into the snowfield."

"Wait first." Johnson said. He actually didn't know much about Tomorrow's Unreal, because as a top scientist, he could not be immersed in the game every day. Moreover, Tomorrow's Unreal is a new game that is not good, so he still has some understanding of the background and plot of the single-player mode, but he was completely confused about what Lu Yuan said: "Can you explain it to me more?"

"There is no time to explain." At this moment, Helen said at the door.

The blonde beauty stood straight at the entrance of the hall: "The live broadcast time has come, please leave with Mr. Lu Yuan and Ms. Su Mei."

Lu Yuan shrugged: "Yes, it's time."

"If Dr. Johnson is interested, you can join us in this live broadcast."

"I believe this must be a very good experience."

"Live broadcast?" Johnson asked, "What live broadcast?"

“It’s not convenient for me to show up in public now.”

"It's okay, it's just a game live broadcast." Lu Yuan shook his head and said, "And no one will show up in public, only the game characters are shown."

"Think about it?" Lu Yuan sincerely invited and extended his hand to the white bear in front of him.

Johnson thought about it carefully, and finally reached out and held Lu Yuan's hand together.

"Then I'll just listen to the Lord."
