"Li Yu, this is a camera you are holding?"

Li Yu's hand was holding something similar to a camera that had just come out, it was erected on a tripod, and it was covered with a layer of black cloth, no matter how it looked, it looked like an old-fashioned camera, so Lin Wanbai asked this question.

"This thing! It's a very interesting thing, and you'll know in a moment what it's for! Li Yu sold a pass.

Lin Wanbai was dissatisfied with Li Yu's sale, so he really came to the tripod and tore off the black cloth: "Tell me what this is!" ”

Li Yu smiled helplessly, "There's no way to take you, I'll just say it briefly!" ”

"As you know, until some issues are resolved, we should not time travel. But in the current situation, the best thing to do is to travel through time and space to conduct research. So I came up with a temporary solution, which was to collect information from the past and then take pictures of it. ”

Lin Wanbai suddenly realized: "You mean, you can use this camera to take photos of the past?" ”

Li Yu wanted to refute it, but after thinking about it, he said: "That's probably what it means, we just need to determine when this research institute was abandoned, and then we can locate the time period and shoot!" ”

The specific process is, of course, more complicated than what Li Yu said. Taking images of the past with a camera is not a simple task, in essence, the camera can be said to have traveled through time and space.

In other words, the target that is photographed by the camera, it can travel through time and space, this is only a relative process, if you only look at the results, this process is negligible.

"How does it work?" Fang Qianmo also came to the equipment that Li Yu had spent three days researching, and compared to the camera described by Lin Wanbai, she thought it was a movie projector.

Its overall appearance is a cube, with a lens ten centimeters in diameter on the front side, and a twist on the top, with complex numbers on it, but Fang Qianmo can still see at a glance that it is to adjust the time.

There is an observation eyepiece in the rear, which, needless to say, is used to observe the target.

"It's very easy to use, you can see the twist above, use it to adjust the time, you can see what happened to the target in the selected time period, if something major happens, it can also save a month's image data."

"It's as simple as that?"

"Well, it's that simple! Actually, it's just a simplified device for me about the space-time scanner. Ever since I knew that if we planeswalked, it would put a lot of pressure on the planes of the past, I had an idea. ”

"If we can't go back in time, how can we observe what happened in the past?"

Li Yu's question, Fang Qianmo also thought about it. Her solution was simple, sending a spaceship to planeswalk. Because of their own strength, the members of the laboratory are prone to disturbing the past time and space, so why don't you go back at all, and send the spaceship back?

But Li Yu's imagination has gone further, I can't go back, so let you come over! Through special equipment, Li Yu can do this, such as the camera in front of him, if it is accurately described, it is more accurate to name it with a space-time observer.

"With this camera you've worked on? A good idea indeed! ”

Li Yu nodded and bowed his head: "That's true!" In fact, the best way is, of course, that we can travel through time and space to visit the site. The other approach is the spatio-temporal scanner I envisioned. The spatiotemporal scanner has not yet been studied, but there is no problem with the scanner for specific targets. ”

"Okay, let's not talk about theories or anything for the time being, let's quickly study whether the prehistoric civilization in the first season has also encountered great changes!"

The prehistoric civilization in the second season can already be sure that they have encountered a great change, and the prehistoric civilization Li Yu in the first season also guessed that they have encountered a great change, but there is no evidence. It can now be determined whether Li Yu's guess was right or wrong.

Lin Wanbai was anxious to know this, so he interrupted Li Yu and Fang Qianmo's previous discussion.

"Yes, who's going to observe?" Li Yu asked the others who wanted to use this simple camera scanner.

"I'm coming!" Lin Wanbai took the lead.

After Lin Wanbai got started, he directly set the observation time of the target to a million years ago, Li Yu originally wanted to say something, but after seeing Lin Wanbai's setting, he gave up.

What Li Yu wants to say is that it is a matter of time.

He wanted Lin Wanbai to determine the time when the institute was abandoned, and then make observations, and saw that Lin Wanbai was directly set to a million years ago, that is, when the Quinn civilization first appeared in this universe, he felt that this time point was not bad, so he didn't say anything.

The camera scanner can only allow one person to observe, and Li Yu and the others have nothing to do, so they can only wait for Lin Wanbai to see the results before discussing.

"Li Yu, I think you thing, can its observation mirror be set to projection mode, so that everyone can observe it? If you do this now, you can only let one person watch it, it's a little inconvenient" Looking at Lin Wanbai's voice of unknown meaning while watching, Fang Qianmo asked Li Yu a question.

"This is also a helpless move! Observing the past is not a simple task. The device I have developed now is just a simplified version, and the principle of its function, let me put it this way, is to play back the time experienced by the target in the interior of the space-time observer. ”

"This kind of playback is still susceptible to external interference, resulting in unstable playback quality. The observation eyepiece on it is equipped with anti-jamming equipment, which can be observed by the outside world. ”

Sun Yixuan felt a little regretful, "It seems that if you want to observe to your heart's content, you can only wait for you to improve its performance." ”

Li Yu was stunned: "Why should I improve it?" At that time, the space-time scanner will be studied, and we will also study the solution to the limitations of time and space, and this temporary emergency equipment has no improvement and value! ”

Together, everyone else thinks so. Li Yu wants to solve the restrictions on everyone's time and space, it is not a problem, Li Yu only needs time, with a more convenient method, this camera, there is really no room for improvement.

"Do you have an eyebrow for the solution?"

"It's been there for a long time! In fact, it's very simple, just shield the fluctuations of our own energy, there are many such methods, I'm just thinking about which method is more suitable, how to use it more conveniently! ”

It turns out that Li Yu has so many solutions?

"Speaking of which, time and space travel is really interesting, people with low energy have no ability to carry it out, and if they have the ability to do it, the space-time energy will be repulsed, it seems that the universe is still very unfriendly to non-spontaneous time and space travel!" Maggie felt it for a moment and couldn't help but say.

That's pretty much what it means. The balance of time and space is the most important balance in the universe, and if the mechanism is not rigorous, this universe will be ruined long ago! However, this mechanism is only aimed at ordinary people, and we will find a way to solve it eventually. ”

This is Li Yu, whether other civilizations can master the real theory of time and space is still two words! At the very least, whether it is in this Celestial Region or the Bone Celestial Region, no civilization has been found in the laboratory that can truly master space-time technology, even if it is a civilization at the Celestial Region.
