The Granx Star Field has been left far behind the laboratory fleet, and Li Yu and the others have officially ended the expedition because of an accidental discovery.

All in all, Li Yu is very satisfied with this inspection action.

During this expedition, the laboratory was hidden behind the scenes almost the whole time, and did not directly appear and participate in the events caused by the Hedgehog.

The harvest is not small.

The most important thing is that the laboratory has set up a reliable space-time authority, which can contribute to the balance of the universe, and at the same time increase the understanding of space-time energy and the essential understanding of space-time travel.

The understanding of the universe itself has also deepened. There was also an unexpected gain, that is, the Lint people, but Li Yu did not expect that he could find another Lint city-level spaceship.

At this time, Lin Wanbai was on the phone with Cheng Yingnan.

"Let me tell you, Sister Yingnan, what we sent back to you this time can make the Time and Space Administration enter the state of trial operation, and you must let the members strictly abide by the staff handbook of the Time and Space Administration that we sent back."

"The precautions for time travel are the most important in the manual. Once you're familiar with the rules in the manual, you're ready to train for time travel. ”

"Our suggestion is that the time travel on the earth should be made before 5,000 B.C., so that there will be as little interference as possible to the historical development of mankind. Once you are familiar with the equipment and regulations, you can do whatever you want. ”

"Also, all the information about the time travel event we encountered this time has also been sent to you. The reference value of the things in there is very high. ”

Cheng Yingnan didn't hear the excitement after being able to travel through time and space, "I know, I said that you need to be in such a hurry?" From the information you gave, it can be seen that although there are many time-space travel phenomena in the universe, most of them are non-impact events, and those that have a significant impact are not on Earth. ”

Lin Wanbai shook his fingers: "Sister Yingnan, haven't you discovered a hidden benefit of the Time and Space Administration." ”

"Li Yu is now working on a specially built spaceship. This ship allows you to travel directly to the plane where the time travel occurred, deal with the time travel event, and then return to the normal plane. Did you think of anything? ”

Cheng Yingnan first looked at Lin Wanbai suspiciously, and then her eyes lit up: "You mean, as long as it is the time and space where the time and space travel occurs, the flight made by Li Yu can be reached, as long as the target is in this universe?" ”

"That's right! It's just that the space-time travel that happens in this universe, and the spaceships that Li Yu has researched can all be reached. Aren't you constantly complaining that we are dashing in the universe while you can only watch from Earth? ”

"With this, you can also explore in the universe, and it sounds even more high-end and atmospheric than the investigation we have conducted!"

Lin Wanbai tried his best to describe the wonderful future of the Time and Space Administration to Cheng Yingnan.

In fact, although the spaceship that Li Yu is researching can travel through time and space, it is not as Lin Wanbai said, it can be explored in the universe.

First of all, the behavior of time and space travel is strictly required, and it is not like Li Yu and others, who can do whatever they want, time and space travel, most of which occur in the present and the past, and more in the past.

Time travel occurs now, which is a rare event, and most of them occur in the past. And back in the day, the most troublesome thing is that behavior is always restricted.

However, Lin Wanbai is not wrong about one thing, the place that Cheng Yingnan can go to is much broader than the place where Li Yu and the others arrived. Judging from the frequency of space-time shuttle events that occur in the universe, Cheng Yingnan can say that she can go anywhere in the entire universe, but space-time fluctuations occur in that place.

"You have a conscience! When will the spacecraft be sent back to Earth? ”

"It will take some time for this, and Li Yu is also going to study some space-time equipment for you, equipment specially used to deal with space-time shuttle events. Well, it will take about half a year. ”

"At this time, you can train your employees and make them mentally prepared!"

Cheng Yingnan hung up the phone with satisfaction, and began to make every effort to prepare for the establishment of the Time and Space Administration, so that it could be set up in the work as soon as possible, as well as the work to prepare for the first time and space shuttle.

Time travel has never been a simple thing. Ten thousand preparations are just basic requirements, and Cheng Yingnan is busy next.

After Lin Wanbai and Cheng Yingnan finished their communication, they teleported to the space.

"Li Yu, I'm done explaining to Sister Yingnan, you have to hurry up your work here!"

"Got it, I don't know when a time travel event will happen on Earth, why are you in such a hurry? If you have this time, you might as well take a look at our inspection report! At the very least, it will give you a deeper understanding of the theory of space-time. ”

"Got it, that's long-winded! I'm here to ask you a question! ”

Li Yu put down the terminal, Lin Wanbai had a problem, of course he paid attention to it: "What is your problem?" ”

"The spaceship you built for Sister Ying Nan can allow her to reach any space-time anomaly, that is to say, she can reach billions of light-years in an instant, can't this kind of engine be applied to our current spaceship?"

"With this engine, won't we be able to reach Grimm's system all at once?"

It turned out to be this problem, Li Yu knew that not only Lin Wanbai had this idea, but Fang Qianmo and the others should also have this idea, so he decided to gather the others together before answering Lin Wanbai's question.

So he pulled Fang Qianmo and the others into a virtual conference room.

"Li Yu, what's the matter with you?" Fang Qianmo was conducting an experiment, and after receiving Li Yu's invitation, she put down the experiment at hand and joined the virtual conference room.

"Wanbai asked me a question just now, and I thought you should be interested in knowing the answer, so I pulled you in. The question Wanbai asked was whether we could apply the engine used to travel through time and space to our spaceship. ”

"Do you have any ideas before I answer?"

Fang Qianmo was indeed interested in this question, "I have this idea, using the space-time shuttle engine, according to your design, it can span tens of billions of light-years at once." Wouldn't it be great if our spacecraft had such an engine? ”

Li Yu looked at the expressions of the others and found that they all felt the same way, so he knew that the next popularization work was very important.

"It seems that you all have a misunderstanding of the function of the time-travel engine. Let me ask you a question, if Cheng Yingnan comes back from the space-time heterogeneous space-time, where will she return? ”

Lin Wanbai was stunned for a moment, and immediately reacted, "It should still be on Earth!?" ”

"You're right, it's still on Earth, or where the Space-Time Authority is located, that is, where they set off, and in this regard, they are actually in normal space, and they haven't moved an inch."

"In other words, the space-time shuttle engine is actually not as powerful as you think, it is just a professional engine, and in normal time and space, it can't even reach the speed of light."

When Li Yu said this, Lin Wanbai understood a little, but there was still a problem: "Then after passing through time, it is billions of light-years away from the earth at once, how to explain this?" ”

"Let me put it this way, in the past time and space, the moment you entered, time and space were actually meaningless, and only after entering did time and space recover. The Space-Time Mapping Engine, which I prefer to call the Space-Time Mapping Engine. ”
