After discovering evidence of the possible existence of higher alien civilizations, Chen Yu should be prepared to return quickly and bring his similar people back to Earth safely.

But the existence of the R-type deep space ship made him full of confidence.

Humans in 6877 were definitely higher civilizations spanning multiple planetary systems.

Chen Yu did not believe that Proxima Centauri would have a stronger civilization than humans in the 60th century.

In the world of technology, changes in every era exceed the world, not to mention the gap of thousands of years.

Therefore, with just one civil ship, Chen Yu had the confidence to beat the second-level civilization under the "Kardashev" system.

This three-body galaxy will not have a civilization of level 2 or above, otherwise the solar system, which is just a short distance away, would have been colonized long ago...

What's more, if the blue light ball is really a detector, then the existence of Chen Yu and his group will have been noticed. In order to ensure the safety of the earth four light years away, he has the obligation to investigate clearly and solve the problems that may pose a threat to the earth.

Standing there, Chen Yu looked at the dazzling double stars ahead, and his brain began to make various plans.

"I wonder if the distance between four light years of detonating a star here will affect the solar system..."

After a while, the spacecraft broke away from the scope of planetary gravity. Chen Yu immediately controlled the hull, pushed the normal navigation speed to the extreme, and began to rotate around the planet.

Looking at the red planet that was spinning rapidly under his feet, Chen Yu explained to the camera: "I'm scanning this planet to 360° to check whether it has life. There are two built-in scanning systems for the spacecraft, one is a Tongque Matter Analyzer and the other is a circularly polarized life scanner. They cooperate with each other to complete three-dimensional reconnaissance of the planet, which is very efficient."

"The analysis of the substance of the same questionnaire was born in 3155, and the actual use was around 4,000 years. As the name suggests, it is used to detect different nuclides of the same element with the same number of protons and different neutrons. By detecting these elements, you can keenly discover whether there are 'artificial' manufacturing elements above the standard amount in the planet. If so, it means that there is a smart civilization here. And the level of civilization has reached the atomic level."

"The circular polarization life scanner was born in the theory and was actually used in the 30th century. The detailed explanation of circular polarization is very complicated, involving physics, optics, and various complex formulas. I will just say it briefly, and it doesn't matter if I don't understand it."

"The amino acids that make up human proteins are all left-handed versions of their respective molecules. When light interacts with these long chains, it will become circularly polarized. Its electromagnetic waves will spiral motion clockwise or counterclockwise and propagate outward. The so-called circular polarization scan is to detect whether there is circular polarization in the planet. If so, it means that there is a creature here."

"Two systems, the latter determines whether the organism exists, the former verifies, and determines whether the organism reaches the level of intelligent civilization."

"Of course, it's worth ironic..." Chen Yu shrugged: "According to the knowledge I have obtained, the first time the circular polarized life scanner is used is not used to find alien life, but to war. It is determined by satellites and then targeted attacks. One hit and one hit is accurate, and it is so exciting."

【…】

【Because of being a human being.】

【Because of being human +1.】

【The real genius is a genius…】

[It's over, all countries must start researching this reminder.]

【Maybe it started long ago.】

[Please cherish the last issue.]

During the explanation, the R-type deep spacecraft completed a circle of orbiting the planets, but neither of the two systems received any prompts.

Chen Yu had no expression on his face, turned his direction, and continued to fly along the equator.

A few minutes later, another circle was over, but there was still no sign of life.

"It seems that it is not on this planet." Chen Yu turned the spacecraft and flew towards the two large stars: "It's normal, it's really not suitable for life to live here. Let's go to the double stars to take a look. I guess there should be a lot of planets there."

"The journey to Tianmen 2 a and b is very long, and you need to start the superluminal speed navigation. However, starting the superluminal speed requires running out of the gravitational range of the red dwarf. Therefore, it takes at least ten minutes during this period."

"Then let's make a very fun game while these ten minutes."

As he said that, Chen Yu pointed to the direction of the solar system: "Look at there, is there a star, right?"

The camera looked over at the same time as everyone in the ship.

"This beauty." Chen Yu walked to Xing Biqi in the corner: "I noticed that you have been looking at that star. Do you know what that is?"

"Solar system."

"How did you know?"

"I...I remember where it is."

Xing Biqi seemed a little nervous when she was staring at her intently. When she thought that hundreds of millions of people would see her in the live broadcast room, her mind was even more dizzy.

"Yes, that's the solar system."

After patting the girl's shoulder, Chen Yu walked into the crowd and talked: "There must be people who are very curious. We took four hours to walk four light years and look back. Can we see the earth four years ago clearly?"

As soon as these words came out, the interactive people on the ship, hundreds of millions of viewers in the live broadcast room, and the scientific researchers in various institutions all shone with their eyes!

This is an extremely interesting experiment for everyone.

"The answer is yes. The solar system we see now is the solar system four years ago, so the Earth is also four years ago. With the telescope technology built in the spacecraft, it can easily obtain most of the light information four light years away. It is no problem to restore the earth's image through the 60th century model filling."

"Then let's start now and see the Earth in 2017."

Chen Yu did it as soon as he said, without any verbalization, and directly turned on the amplification function in the direction of the solar system.

"Swish!"

"Swish!"

"Swish..."

As the distance narrows, the solar system, which was originally like a star, became like a full moon.

Jupiter and Saturn are also clearly visible under the reflection of the sun.

"See it? This is the solar system four years ago. The planets are completely different from now."

As he said that, he continued to zoom in.

"Swish..."

The blue earth appeared in the picture...

【Awesome!】

【Earth four years ago!】

【I've traveled through time!】

[Can you still enlarge the anchor? Look at the internal organs.]

【magic.】

[I have decided! Learn astrophysics in the future! It's so romantic!]

[Brother, I believe in me, I would rather study medicine than get involved in astrophysics. It is still time to look back now.]

[This review is really high-energy throughout the whole process! Just like watching a movie, stinger.]

"You are in the Earth in 2021, but you see the Earth in 2017 through my live broadcast room. From a certain perspective, this is also a kind of time and space travel."

"But with my current position, I can't adjust the direction at will, so I can only see a corner of the eastern hemisphere, barely reaching the border of China. It should... be the territory of Yunnan and Guizhou, right? Let's continue to zoom in now and try to see the telescope of the spacecraft."

After the words came, he controlled the screen and pulled it closer again.

Everyone in the hall, including Xing Biqi, quickly approached Chen Yu, stared at each other, and waited for the next magical scene...
Chapter completed!
