After saying goodbye to the navigator, Ye Zhou walked out of the centrifugal cabin along the gangway. The instant disappearing gravity caught him off guard, and his brain felt a little confused. But soon, the instinct of long-term training once again controlled his body. He began to float forward in a gravity-free environment, while observing everything around him.

Obviously, this area is the main body of the spacecraft. The huge hull is surrounded by 12 working fluid engines for propulsion. These engines are not ignited at this time, and they just stay so quietly, as if they are lurking giant beasts.

The one who is truly responsible for the power of the spacecraft are the two working fluid-free fusion engines at the back end of the centrifugal living compartment. It is the engines in the past two days that have allowed the spacecraft named "Wei Qing" to cross 800 million kilometers to come from the Earth, the human parent planet, to this completely unfamiliar galaxy.

Ye Zhou touched the wall beside him, and the holographic screen lit up. As his thoughts flashed, the screen began to follow his sight and showed the scene of the spacecraft. Soon, Ye Zhou found his target.

Io.

This satellite is the most intense volcanic object in the solar system. It has a diameter of more than 3,600 kilometers and is scattered on the surface with more than 400 active volcanoes scattered on the ground.

Due to the gravity and tidal force of Jupiter and other satellites, the Io formation was extremely twisted and rubbed continuously. With constant friction, the volcano erupted violently. The eruption height could reach up to 480 kilometers from the surface and the temperature could soar to 1800℃.

It is Ioyu, which is like a terrifying purgatory.

Silicates, sulfur, sulfur dioxide and other surfaces are made of holes, and they are accompanied by strange and bright colors. Even if you look from a distance, you can feel a sense of suffocation that seems to be from the ancient times.

Now, the distance between Wei Qing and him is only 150,000 kilometers.

On the scale of the universe, this distance can be said to be a passing by.

Ye Zhou once couldn't understand the so-called "giant phobia". He felt that those things were just a little bigger and there was nothing scary. After all, who doesn't like big things?

However, when Io Dai gradually occupied the entire porthole in the holographic simulation video, he suddenly felt a series of heartbeats after wave.

The feeling of being shrouded and swallowed is probably the real "giant fear".

"What are you stupid here?"

The person floating behind him once again interrupted Ye Zhou's thoughts. When he looked back, the information flow immediately showed the identity of this person.

This man's name is Xu Chang. Like himself, he is also an engineer of the Wei Qing working fluid engine. In future operations, he will control the work of the fusion engine with him to provide the spacecraft with enough power to shake the asteroid.

"No, I just saw Io passing by, and it was a little shocked."

Xu Chang nodded and replied:

"I've seen it twice, it's really scary. Although I know we're still outside its capture distance, I can't help but tremble every time it passes... I didn't feel like this before in Earth's orbit."

Ye Zhou smiled and said:

"Can this be the same? The earth is a livable environment, and it is a hero if it lands. If it lands, Io... If it lands, it will probably not be even ashes left."

"That won't be that the materials of the fusion engine are resistant to high temperatures, and at least the engine can leave a whole body."

"......... There is actually no need for such rigor here, right?"

"Hahahahahaha, just kidding. How are you doing there? Is the filter working in normal?"

Hearing this, Ye Zhou shook his head. He did not forget the task he was going to perform in the simulation.

"The last time I checked everything was normal and the pilot fire was normal. I just don't know if it can withstand high temperature, high pressure and radiation impact in extreme environments."

Xu Chang frowned and said hesitantly:

"It should be fine, right? The ground test and space test were both smooth, and there would be no trouble in actual operation... Why, you don't have confidence?"

In the simulation, Ye Zhou is the chief designer of the entire fusion reactor filter. If he says he has no confidence in the filter, it will have a significant impact on the entire plan.

But even so, Ye Zhou still said cautiously:

"We have never conducted full load tests, and time constraints are one aspect, and necessity is also one aspect."

"According to design parameters, 48 ​​engines are more than enough to drive the carme, and they cannot reach full load."

"But the problem is that we don't have a chance to try it out again, and once we start, we have to go all out."

"I guess, when the implementation is really started, all four of our spacecraft will enter full load mode--you know, there are many people on this batch of push ships who didn't even think about going back alive."

"If this happens, it will be a great test for the engine, especially the filter bias."

"If the furnace can hold on for one more minute, our success rate will increase by one percentage point."

Xu Chang nodded, patted Ye Zhou on the shoulder and comforted:

"Don't worry too much, hasn't the simulation been passed? Believe in our processes and technology."

"Besides, full load testing is too dangerous. You can't just blow up a group of people before the earth even came out? This is also a consideration above."

"Besides, we may be a little reckless, but we are not brainless people. They will consider what situations need to be handled by themselves. We just need to provide technical support."

Ye Zhou sighed deeply without answering. Xu Chang was speechless when he saw his expression.

After a moment, he suddenly laughed inexplicably, and Ye Zhou looked at him in confusion and asked:

"why are you laughing?"

Xu Chang shook his head and replied:

"I just think it's quite Coke... Think about it, the neighboring dimension invasion, the higher civilization, we are now using such primitive means to deal with their attacks, and it's still useful.

”

"explode!"

"As a matter of fact, explosion is the source of everything... By the way, have you ever thought before that the overall logic of adjacent dimension invasion would be so simple?"

What Xu Chang mentioned is actually about the Silad enrichment effect. According to this theory, the spatial channels invaded by adjacent dimensions will be enriched in high-energy areas and will continue to transfer with the transfer of energy sources.

This theory has been verified for hundreds of years and has never had any problems, which proves one thing:

The so-called "higher civilization" opposite does not seem to be that high.

At least, their acquisition of the "information" in this dimension where humans are located is actually extremely limited.

Thinking of this, Ye Zhou replied:

"The logic is simple, but effective -- this is more important than anything else."

"No matter what stage of civilization development they are, at least they have pumps, and we don't have one yet, that's the key to the problem."

"No, no, that's not what I mean."

Xu Chang shook his head repeatedly and then continued to ask:

"I want to say, do you have a feeling that maybe the civilizations on the other side have gone astray?"

"Did you go off the wrong way? What does it mean?"

Ye Zhou asked in confusion.

Xu Chang breathed a sigh of relief and then asked:

"Have you heard of the interstellar pirates?"
