Xue Yu didn't expect time to pass so quickly, three years had passed in a blink of an eye, it was incredibly fast, and he was a little caught off guard.

"It's time to go back!"

Sighing slightly, Xue Jun and Xiao Jin discussed for a while, and then started to act, first of all, he released a miniature robot the size of a grain of rice to probe the outside world to see if there were monsters.

"Good chance!"

As a result, it was quiet outside, and after not seeing a single monster, Xue Jun couldn't help but be overjoyed, and his figure flew out of the neutron battle star in a flash, and then found the exit of the giant well, and flew out without saying a word.

"Quack~~"

Who would have thought that as soon as he flashed into the giant well, there was a deafening sharp neigh behind him, like a galloping horse, and like a giant baby roaring in unison, Xue Yu's scalp exploded violently, and a buzzing roar came from his head.

"Not good!"

Xue Yu was shocked, his body suddenly accelerated, turned into a bolt of lightning, and rushed outward.

"Poof—"

A few minutes later, he finally rushed out of the giant well, but as soon as he stopped his body, he couldn't help but open his mouth and spurt out a mouthful of blood, and there was also blood coming out of his nostrils and ears.

"Damn! Fortunately, I escaped quickly, otherwise I would have died below! ”

Xue Yan was shocked, the momentum on his body rose, and the blood that flowed out evaporated completely, and then he looked at the giant well with palpitations, and his face still had a look of fear.

He knew very well that his current soul had evolved to the seventh or third level, and in the face of a monster's soul attack, he could barely resist one or two, but if he faced countless monsters and launched a soul attack at the same time, he would have to be killed in one face.

Luckily, I ran early and escaped quickly!

"I'm glad I escaped alive, but I have to do something before I leave......"

A hint of strangeness flashed in his eyes, and with a wave of his hand, Xue Yu released all the robots in the Neutron Battle Star, and with a cursory sweep, there were billions.

"From now on, you are the person in charge here, and your task is very simple, that is, to lead the other robots and steal the Ice and Fire Divine Essence below!"

"Remember, steal as much as you can, and the more you steal, the better!"

Each robot is made by a seventh-level civilization, with absolute high intelligence, and its IQ is not inferior to Cybertron and Manta, the only drawback is that they are all puppet intelligent lifeforms, and they are controlled by people all their lives, and there is no freedom.

Xue Yu designated one of the robots and asked him to be the head of the team and lead the other billions of robots to complete the task of stealing the Ice and Fire Divine Essence.

"Yes!"

This robot respectfully should be!

"I wonder how many of these billions of robots will be left when I come back next time?"

Xue Jun glanced at the dense robots, and couldn't help but shake his head: "However, it doesn't matter, as long as I can get the Ice and Fire Divine Essence, even if they are all scrapped, I won't feel distressed at all!" ”

"Well, before leaving, you have to prepare a large vat to hold the Ice and Fire Divine Essence!"

Immediately afterward, Xue Yu spent several hours creating a large alloy giant and shelving it on the ground to hold the Ice and Fire Divine Essence.

This barrel covers an area of tens of kilometers, with a height of 10 kilometers, and the barrel wall is up to 20 meters thick, which is unusually strong.

"Remember, if you steal the Ice and Fire Essence, you will pour it into this bucket, understand?"

"Understood!"

"Good!"

Xue Jun took one last look at the dark giant well, his figure flashed, turned into a streamer and disappeared without a trace, and after a while, he came to the wormhole.

"It's finally back!"

Walking through the wormhole, returning to the earth, bathing in the warm sunlight and breathing the familiar air, Xue Jun was extremely satisfied.

"It's still comfortable on Earth!"

Out of the wormhole, it was daytime at this moment, the sun was shining in the sky, shining on the vast ice field, reflecting a dazzling light, Xue Jun squinted his eyes slightly, adapted to the light of the earth, and then habitually released the power of the soul to investigate.

"It's going well!"

With the continuous exploration, the scenes of the earth came into view, Xue Yu couldn't help nodding again and again, compared with three years ago, the earth has changed a lot.

Materially speaking, it is more affluent, more populous, and all kinds of developed means of transportation shuttle back and forth, becoming more and more prosperous.

Technologically, there has been a lot of change compared to three years ago.

In short, the earth has made considerable progress on a relatively stable basis.

"It's good that nothing happened! It's good that nothing happened! ”

Xue Yu let out a long sigh of relief, what he was most worried about was that he would leave, the Kayu Universe Kingdom would come to attack the Dana Universe Country, causing the Golden Dragon Empire and the Earth to be affected, that would not be good.

"Now it seems that I am worrying about the sky!"

"But it's also a little strange, what about the people of the Kayu Universe Kingdom?"

As long as the earth was fine, Xue Shu's heart let go of most of it, and then he teleported towards Yanlong Star in a happy mood.

Yanlong Star is still operating normally, and the science giant city is developing steadily, especially the technology sent by Xue Yu three years ago, and the speed of development is even faster.

Major breakthroughs occur almost every day.

In less than three years, the means of transportation on the earth have changed, and they have directly leaped from a regressive second-level civilization to a fifth-level civilization.

Yes, all the vehicles on the earth have been redressed and turned into technological products of the fifth-level civilization.

Originally, after the isolation of Planet 38, the scientific and technological civilization of the earth seriously regressed, from the fourth-level civilization to the previous second-level civilization, and the means of transportation returned to the previous explosive power tools.

Even due to the ravages of monsters, the vehicles on the earth were seriously damaged, and there were only a few left, but with the establishment of the science giant city on Yanlong Star, in just three years, the earth was greatly redressed!

Taxi, buses, trains, high-speed rail, airplanes, and ships have all taken on a new look and become the latest five-level civilization products.

The energy system, from the previous explosion power system, has become an elemental decay technology system, which directly spans thousands of years, or even tens of thousands of years.

It's as if you have traveled from the 21st century to tens of thousands of years later!

In the face of such a major change, the earthlings did not feel much surprised, and with the strong propaganda of the federal government, they quickly adapted.

People don't have to spend much money to have their own private transportation.

The productivity of science megacities is terrifying, hundreds of millions of flying machines can be built in a day, that is, it only takes a few days to build a flying machine for everyone on the planet.

A steady stream of alloy raw materials were transported from the Golden Dragon Empire, and then synthesized, manufactured, and produced in the science giant city, and the earthlings directly sat back and enjoyed the results.

Be the ultimate beneficiary!
