"It's ......"

When the professor led his students to the place where their guardians had arranged for them, they were instantly amazed by the grandeur of the place.

This is a "synthetic" city.

A large number of buildings are clustered one after the other in a prototype area, perfectly planned in advance that does not appear crowded and makes the most of every space.

Starting with metal floors, we continue to soar into the sky, one-piece towers.

From a multi-purpose amusement park that covers an area of several square miles, to a rice cooker connected to a metal base.

Everything in the city, including the city itself, is "synthesized" into something much larger.

In layman's terms, this is a city printed by a super-large 3D printer.

“…… Can you still have such thoughts? What a terrifying civilization......" Cooper's words were filled with a deep sigh, and his heart was also afraid.

He felt that he was a great blessing that he had never spoken ill of the "guardian" from beginning to end, and he could not imagine how powerful such a civilization was in its heyday, and that the Rabon Federation established by his own race might not even be a speck of dust in front of them.

"It would be easy for them to build a civilization that could build that kind of warship, and to build that kind of city." The professor was also amazed, and his eyes were full of fascination, as if what he was looking for was not a city but a work of art.

Li Wenyuan, the words touted by these aliens, is also quite comfortable to listen to, although the construction of this city has nothing to do with him, but who doesn't like to look at the envious eyes of others?

And their speculation also caught Li Wenyuan's attention, and after calling up the technology tree, he flipped through it.

"I guess the city must have used this technology, right?" With that in mind, he found the technology in a dark foliage.

【Large-scale printing project】

[Technology Level: 5]

[Introduction: In the past, the production line has greatly increased our industrial capacity, and the assembly plant has become synonymous with high efficiency. But in an age where products are becoming gigantic, we should try to find ways to be more efficient. Like what...... A machine capable of printing cities]

[Possible Technology: Synthetic Fleet (0%); Jumbo Printing Project (0%); Megastructure construction (0%)】

Li Wenyuan did not light up this technology, and the "synthetic city" in front of him is one of the legacies left by mankind.

However, there is only one city on the planet that is like this, indicating that the prospects of this "large-scale printing project" are not very optimistic, and mankind has only experimented once and then gave up.

Otherwise, there should be such "synthetic cities" everywhere.

After approaching the city, Li Wenyuan remembered one thing and said to the aliens:

"Speaking of which, if you want to use the city's facilities, you need to be connected to the internet......

"You're not robots, and you won't accept the method of implanting chips, so let's use this for the time being."

He pulled out something like a tablet and gave it to each of the aliens.

"There should be a lot of similar things in the interstellar, I believe that with your IQ, you will be able to adapt quickly, if you have any questions, contact me through this."

After saying this, he turned around in a dashing manner, took off directly on the spot, crossed an arc in the sky, and disappeared into the eyes of the aliens.

And the aliens also looked at each other, and Cooper couldn't help but say:

“…… Just gone? Don't have to spy on us? ”

The professor sighed and said helplessly, "For this one, the entire planet must be under his supervision, and so far, have you seen any other outsiders?" ”

"If I'm right, this person is probably a 'civilization'."

"Cultivate your heart these days, and be prepared to never go back for the rest of your life......

……

Li Wenyuan didn't hear the aliens' discussion, his control of the synthesizer flying away was just an illusion, in fact, his consciousness data returned to the guardianship core the moment he took off.

At this time, the autopsy results of the extremely confident alien named Hus also came out, and Li Wenyuan was curious about how he manipulated gravity.

And the answer is in front of his eyes.

In a laboratory in the research zone, a white crumb the size of a grain of rice is bound in the center by a powerful stand.

This is a special substance extracted from Hus's corpse, which also surprised Li Wenyuan.

Here's how it is presented in the database:

【Activated Neutron Star Matter】

[Introduction: The high-density neutron star material is artificially stripped away, and through a certain process, it still maintains the neutron degenerate state.] There seems to be a special group of people in the universe who can use this neutron star material to generate gravitational attraction in a small area.

“…… Even this race that is almost equal to superpowers? Li Wenyuan's brows furrowed, a little incomprehensible.

Knowing that this neutron star the size of a grain of rice weighs 10 million tons, he doesn't know how Hus, an ordinary and stupid alien, could keep it in his body without being torn apart.

“…… It can't have anything to do with those idealistic civilizations...... "The thought of that unscientific existence gave him a headache, and he wanted to dig out Newton's coffin and let him see for himself what "magic" was.

"But thanks to him, I've unlocked a new technology."

As the voice turns, the tech tree is once again displayed in the virtual world. Located in the middle level, there is also a technology that is lit up by a solitary light.

【Elemental Materials】

[Tech Level: 6]

[Introduction: High-density neutron materials may be able to solve the problem of warship protection that has plagued us for a long time.] After that, all attacks will be part of it.]

[Possible Technology: Elemental Armor (0%)]

This branch of "zero-element materials" ended with zero-element armor, which made Li Wenyuan a little surprised.

"It's a pity that I didn't light up the pre-technology 'zero-element mining', and I can't use this technology." Lamenting that he had one more technology that he couldn't use for the time being, he turned his attention to a project that had been completed not long ago.

“…… With this, there shouldn't be a need to worry about resources......" His eyes lit up, and his digital gaze was full of anticipation for the future.

At this time, a huge "black box" slowly rose from the earth.

This is a newly repaired "dimension maker" that can extract resources from parallel universes and realize the "creation of something out of nothing" in this universe.

Its main facilities are all in this huge "black box" covering an area of thousands of square kilometers, although it is much smaller than the "fourth-level singularity", it is a very special facility.

Li Wenyuan still remembers that the restoration drawings specifically stated that no personnel could be placed in the "black box" after the "dimensional manufacturing machine" was activated, not even robots.

At the same time, it is not possible to directly observe the inside of the "black box" with a device such as a monitor, and even if there is a problem and needs to be repaired, it must wait for the "dimensional manufacturing machine" to be shut down before entering the maintenance.

It can be said that, according to the special instructions in the drawings, after the "dimensional machine" is activated, it is a forbidden observation area that is not approached by the living.

Although the resources produced will be transported to the outside world through fully automated transportation pipelines, there is always a creepy feeling when looking at those special instructions for Li Wenyuan.

“…… Forget it, are there more strange things in this universe? Let's think more about the present. He didn't have any intention of going against the specifics, and had the synth pass through the indoctrination equipment from the outside world to deliver the last condition of the repair process, Zelo, into the "black box".

After that, it was calm, there were no explosions, and there was no weird light.

The world is still functioning normally.

But Li Wenyuan, who was looking closely at the planet management interface, gradually smiled.

[The current planetary energy output is about: 120,000 units of energy]

["Data Corruption" Energy Consumption: 72,000 Unit Energy]

[Energy consumption of dimensional manufacturing machine: 5000 unit energy]

……

[The current energy income is about: 15050 units of energy]

The dimensional machine began to operate normally, and he saw the soaring output value.

"It's good to have more things...... After I grow it for ten or eight years, I should be able to see the world on the interstellar stage, right? ”
