Qiao Lu and Ding Yi waited on the wheat field for a while, and soon an anti-gravity boat flew over from a distance, like a flat boat floating on the golden ocean, and then slowly landed, keeping a distance of about 30 centimeters from the ground and opened the door.

"Get in the car."

Ding Yi walked into the passenger seat by himself, and Qiao Lu and 2B also sat in the back row.

The design of the cabin has not changed drastically, but the driver's seat is empty.

Ding Yi explained: "Under normal circumstances, these vehicles are unmanned, and only in unfamiliar environments or complex terrain do people need to drive. Nowadays, pilots are just like pilots of our time, and they can't be tested casually. ”

During the conversation, the anti-gravity boat gradually rose into the air, and Qiao Lu had to look down at the wider ground.

It has to be said that the surface of the wandering earth today may not look as prosperous as it was more than 2,000 years ago, and there are no large-scale urban settlements in sight, only a beautiful countryside, like a paradise.

"Are there no more cities on Earth?" Qiao Lu asked curiously.

"Of course there is, but the coverage rate is not so high, leaving more space to maintain the natural ecology."

After all, now the earth is used for living, and industry is transferred to space. People certainly want to live in a secluded place and then return to the bustling city to work.

As he spoke, the anti-gravity boat began to accelerate, like a meteor crossing the sky, and in a blink of an eye, he left the field with Qiao Lu and his party.

While the change in scenery from the window can be felt as fast as a supersonic fighter, there is hardly any feeling of acceleration overload in the cabin.

In an instant, the anti-gravity boat came to the sky above the city that Ding Yi said, and here Qiao Lu finally saw the familiar building - the planetary engine.

The whole city is built around the planetary engine, but the planetary engine stood out among all the buildings at the beginning, and the height of tens of thousands of meters is the existence that other so-called high-rise buildings can only look up to, which is like a toothpick in comparison.

However, today, the planetary engine is surrounded by countless buildings of the same height, or even slightly better, and tens of thousands of meters of buildings can be seen everywhere, forming a huge forest together.

Slender tree trunks jug into the sky, and each trunk has branches of varying lengths perpendicular to it, and other buildings hang from these branches like leaves.

Pedestrians in the city walk on these branches, and vehicles use anti-gravity technology to weave through the trees. The whole city is completely three-dimensional, and I don't know how many floors there are from top to bottom.

The planetary engine towers in the middle of such a city, and although it has been surpassed by the surrounding buildings in height, its blue light is still a conspicuous sight to shoot into the sky.

"Where is this?" Qiao Lu asked in surprise.

"Sulawesi." Ding Yi replied as a matter of course.

The Sulawesi equatorial engine was the last stop of the rescue team formed by Liu Qi and others, and it can also be said to be the place where the wandering earth crossing incident was induced.

I didn't expect to come here after many years, and now there is no trace of the implementation of the Wandering Earth plan except for the planetary engine.

Ding Yi suddenly pointed down excitedly and shouted: "Look below, Einstein equator!" After two years of hibernation, I finally got it done. ”

Looking in the direction he was pointing, Qiao Lu saw a massive accelerator pipe, passing through the planetary engines, across the city, all the way to infinity.

Einstein's equator circled the entire wandering earth, of course, it was impossible to see the end, and Qiao Lu regretted that he could not see it completed, but he didn't expect to make up for it so quickly.

"Then do you get the grand unified model of the universe?"

Qiao Lu still remembers that this is Ding Yi's lifelong dream, and it is also the original intention of Einstein's equator.

Ding Yi shook his head and sighed: "If it had gone so well, I wouldn't have hibernated until now." There has never been a way to avoid vacuum decay, not even the technology of pre-human civilizations. It may really be that only by destroying the universe once can we get the grand unification model. ”

Such an idea is really crazy, but for Ding Yi, it may be the truth.

Qiao Lu didn't comment on this, after all, in a sense, he was also waiting for the day when the universe would be destroyed.

"So what did Einstein do with his equator?" Qiao Lu changed the subject and asked.

Ding Yi replied impatiently: "What else can I do, large-scale antimatter mass production experiments, and further research on dark matter energy, anyway, they are all uninteresting experiments." ”

"What do you call it meaningful?"

Even if Qiao Lu's understanding of science is far inferior to Ding Yi's, he can know that these studies are very important to human science and technology, and it is really embarrassing to be said by Ding Yi to be an uninteresting experiment.

"But now I've finally waited for the opportunity, and look, I'll always get the grand unified model of the universe."

Ding Yi said confidently, making people wonder where his confidence came from, no matter how you look at it, this is not an experiment that can be approved.

"What the hell is going on?" Qiao Lu couldn't help but ask.

Ding Yi deliberately sold a pass and said: "Don't worry, this matter is also related to you, let's talk about it when we arrive." ”

The anti-gravity boat flew straight towards the pillars of light ejected from the planetary engines, and it seems that the planetary engine transmission towers are still an important transportation hub in this era, especially when it comes to access to outer space.

In addition to the anti-gravity boat that Qiao Lu and the others were on, there were other vehicles gathering on the side of the planetary engine, after all, it was an important transportation hub, and of course, Qiao Lu was not the only car in line.

However, when Qiao Lu's anti-gravity boat approached, the traffic in front of him took the initiative to give way to both sides, and since these vehicles were unmanned, it was obviously set automatically by the computer program.

The passengers on these aerial vehicles also poked their heads out curiously to look around, trying to know what was causing it.

Some people who are in a hurry can't help but complain that they are going to work in space, and the delay on the way to work will certainly make them unhappy.

However, all these complaints came to an abrupt end the moment they saw the license plate of Joe's anti-gravity boat, and were replaced by extremely respectful gazes, as if they saw an ambulance going against the road, and the police car chasing the gangsters was speeding.

Qiao Lu began to realize that behind Ding Yi's visit, things might not be so simple.

In the final analysis, Ding Yi does not have the ability to decide for himself when to wake up Qiao Lu, so it is self-evident who made the decision.
