The sky was gray, and the lightning was like a snake and a dragon fighting. It was a sunny day, but suddenly it rained heavily.

The cold wind accompanied by the rain mercilessly slapped on Bai Xiaodao's body, and a chill instantly surged into his heart, and he couldn't help but shiver, and continued to walk towards the dormitory in the heavy rain.

The teaching building is several hundred meters away from the dormitory, and the white knife was originally with an umbrella, but unfortunately it was "borrowed" by others halfway.

"Fucking Wang Dafu!"

The white knife smacked a mouthful of rainwater, where is that guy borrowing, it's clear that it's robbing! Although his heart was full of anger, Bai Xiaodao could only hold back this anger, so when Wang Dafu borrowed an umbrella from him, he still had to pretend that he was willing.

There's no way, a student like him, who has no power, no power and no money, really can't afford to offend Wang Dafu, a bastard.

"The thief of the mud horse, why is it raining so decently!"

Just as the white knife stretched out two middle fingers into the air, something slammed into his head so hard that he almost burst out of the.

"Which guy smashed me!"

It was a pain second only to egg pain, and it seemed like the head had been smashed open.

Covering his head and looking around, Bai Xiaodao did not find any suspicious people, at this time, the rain was pouring down, and the students who had umbrellas and did not have umbrellas all went to the cafeteria, and he was the only one nearby who walked towards the dormitory in the rain.

Could it be hail? If you think about it, it is unlikely, after all, the probability of hail in this weather is simply lower than the probability of winning the lottery.

At this time, Bai Xiaodao suddenly found a ring with a metallic luster under his feet, and he quickly bent down to pick it up. Take a closer look, the shape of this ring is very high-end and high-grade, in addition to the surrounding 8 small "diamonds", the raised position in the middle is also inlaid with an oval sapphire.

"If this thing really is worth anything!"

Is this what is called a windfall? Bai Xiaodao was a little excited, and he forgot about his headache when he was excited.

He tried to put the ring on the middle finger of his left hand, and suddenly the ring began to vibrate and spin!

"Authentication failed, do you want to re-authenticate?"

Suddenly there was such a voice in my head, and the ring seemed to be alive, not only did it turn automatically, but it also shrank in a circle just enough to tightly cover the fingers of the white knife!

"Authentication failed, do you want to re-authenticate?"

After a few seconds, the voice came back in my head. Bai Xiaodao was completely stunned, he said a weak "yes", and the ring began to tremble and spin again, and finally clasped his middle finger.

"Authentication failed, do you want to re-authenticate?"

"No!"

As soon as the words fell, the ring stopped trembling or spinning, but the sapphire on it suddenly flashed a blue light, and then a clear screen appeared in front of the white knife out of thin air.

This abrupt phenomenon really startled him, the light screen that suddenly appeared in front of him was just like the fiction in a science fiction movie!

Hurriedly took out the ring, and the white knife ran back to the dormitory quickly, and he didn't care about getting wet, he went directly into the toilet of the dormitory, and then put the ring back on.

"Authentication failed, do you want to re-authenticate?"

"No!" Bai Xiaodao replied excitedly.

Immediately, a dozen inches of ultra-clear screen appeared out of thin air in front of him, judging from the screen, this ring is just like the fictional projection computer in science fiction films, what is even more amazing is that this air screen seems to be generated in the air, even if the ring is covered, it will not affect the appearance of this screen at all!

The index finger of his right hand trembled and clicked on the registration icon, and Bai Xiaodao was apprehensive to fill in the information, and then carried out fingerprint iris and other authentication, which obtained the control of this ring.

Immediately afterward, the white knife fiddled with it in confusion for half an hour before he figured out the true origin of the ring.

Super Ring Computer? This is actually a supercomputer in 2320! If this is true, then how did it end up here? Could it be that the humans of 2320 invented the legendary time machine!

As soon as this idea came out, Bai Xiaodao was a little uneasy, if human beings really invented a time machine three hundred years later, wouldn't the world be chaotic at that time?

Continuing to open the browser, Bai Xiaodao carefully checked the news three hundred years later. This super ring computer is really powerful, a small ring actually has eight miniature versions of super photovoltaic cells built-in, and it is also equipped with many delicate objects.

It is said that the Super Ring Computer can use the Internet signal no matter where it is, even in outer space, because it has a called a neutrino network chip installed in it.

Soon an hour passed like this, and if it weren't for the fat man's call, Bai Xiaodao would still be immersed in the future world 300 years later.

Unexpectedly, 300 years later, the earth has become an intelligent machine kingdom!

Due to the progress of science and technology, the life expectancy of human beings at that time could be extended to two or three hundred years. However, due to the increasingly harsh environment, the earth is becoming more and more unsuitable for human habitation, so people can only go to habitable planets, or hide in the underground cities of the earth, and use the power of science and technology to survive.

The polar climate has been significantly enhanced, and in 300 years, the earth will have a high temperature of more than 50 degrees Celsius in summer, and on the contrary, once it is winter, the world will become an icy world of tens of degrees below zero.

It is precisely because of the harsh climate of the poles that various natural disasters frequently occur on the earth, especially the high temperature that only rises but does not fall every summer, leading to a large-scale desertification on the earth, and most of the animals and plants are becoming extinct......

Fortunately, biotechnology at that time had successfully cultivated extinct organisms, so even some ancient creatures could be cultivated as long as the DNA on the fossils was collected.

Bai Xiaodao stared intently at the air screen, in 2201, human beings explored the mystery of the chrono tunnel, and after 98 years of repeated research, people finally had a way to enter the chrono tunnel. The most surprising thing is that in the chrono tunnel, any object that can move can travel through every corner of the universe at a speed several times that of superlight.

The speed of light is about 300,000 kilometers per second, and in the chrono tunnel, objects move faster than 1,000 times the speed of light! The speed is staggering light-years! It can be seen what a terrifying number this is!

Although Bai Xiaodao's results were not very good, he was still familiar with the distance unit of light years, so when he learned about the information of the Chrono Tunnel, the whole person was already stunned.

Three hundred years later, humanity has not developed a time machine that can travel between the past and the future, could it be that this ring fell here during the reverse current of the chrono tunnel? But if you calculate it at the speed of light, then this ring should cause a huge shockwave when it falls to the ground! But the ring looks intact, what is the reason for this?

Bai Xiaodao couldn't figure it out, the only thing he was sure of now was that this ring was a high-tech product from the year 2320!

At this moment, Bai Xiaodao's heart was like being beaten with chicken blood, and his brain suddenly thought of many possibilities.

So, can I connect with the world 300 years from now? If so, can I travel back in time to 2320?

In the past 17 years, Bai Xiaodao has almost lived in the way of hanging vegetables, and now he seems to see how bright his future is!

With this super ring computer, even if I can't get into a good university, I can be promoted and raised in minutes in the future, become a general manager, become a CEO, marry Bai Fumei, and go to the peak of life!

Hehe, it's a little exciting to think about...... xh:.74.240.212
