At this time, no matter how Lu Xingchen increased the power, the speed was 50% of the speed of light and it was difficult to advance any further.

"Well, maybe we've reached the bottleneck of current technology..."

Lu Xingchen adjusted the parameters at this time, allowing the water drop aircraft to reach a perfect state.

"Okay, now let's try out the simple primary compression device!"

Lu Xingchen took out a unit of water and carefully added it to the device.

As the device started up, Lu Xingchen began to observe the state of the water through the device's display.

After a while, the water became unstable and the temperature began to rise.

Soon, the water was pressurized to a boiling point.

"Yeah, that makes sense. Keep increasing the pressure!"

Lu Xingchen increased the speed of pressurization, and the pressure directly reached 100,000 atmospheres.

"Oh my god, it really turned into ice crystals!"

At this time, all the hydrogen-oxygen bonds in the water are broken, and the water becomes a polymer of hydrogen atoms and oxygen atoms.

As the pressure continued to increase, the temperature of the mass continued to rise.

At this time, the molecular gap begins to decrease continuously with pressure.

After a while, a partially ionized plasma was born.

But the water that was there before no longer exists.

"Things are starting to get interesting, keep the pressure on!"

Lu Xingchen directly increased the pressure to one million atmospheres!

At this time, the distance between the atoms of this mass of matter becomes very close and the temperature rises extremely.

"Can the device still withstand the pressure now? Why doesn't this system have a tolerance chart?"

As soon as Lu Xingchen finished speaking, the mass of matter began a fusion reaction.

"Who cares! Keep applying pressure! I don't believe it will work. Blow me up if you dare!"

Lu Xingchen began to click the pressurization button frantically, and the pressure soared directly to 40 million atmospheres!

At this time, the mass of matter began to change slowly and eventually turned into a metal.

"My goodness, is this metallic hydrogen?"

Lu Xingchen immediately began to look up the effects of metallic hydrogen.

"Superconducting material? Oh my god! If this could be mass-produced, not to mention becoming the richest man on Blue Planet, it would be a huge advancement in technology!"

Lu Xingchen was not satisfied after reading the materials and continued to increase the pressure.

Soon, the pressure reached 200 billion atmospheres!

At this time, this mass of matter began to become extremely unstable, and the hydrogen atoms began nuclear fusion to become helium!

At this moment, the device was equivalent to a hydrogen bomb explosion!

Lu Xingchen quickly moved a little further away to observe the status of the instrument.

"There's no reaction at all? The system is so buggy!"

Lu Xingchen didn't believe it and continued to increase the pressure!

Gradually, the helium began to fuse. At this time, Lu Xingchen gradually slowed down the speed of pressurization, otherwise it would be embarrassing if he couldn't bear it.

After helium fusion, it became carbon, and the periodic table of elements appeared in Lu Xingchen's mind at this time.

"Oh my goodness, if this continues, will the entire periodic table be fused?"

"Logically speaking, it's impossible! At most, it should become iron and then it will stop working!"

Lu Xingchen began to observe and record the data carefully.

After a long wait, the device finally fused iron and stopped transforming.

Lu Xingchen looked at the pressure value and was so surprised that he couldn't close his mouth.

"This...this is...too terrifying! This pressure is several times greater than that of a collapsing star!"

But looking at the device that was still calm, Lu Xingchen gritted his teeth and stomped his feet, and an obsession emerged in his mind: "Keep going! Don't stop!"

"Come on! Show me what this can become!"

Lu Xingchen pressed the button hard, and the pressure continued to soar!

At the same time, Lu Xingchen enlarged the image of the material in the instrument and began to carefully observe the state of these iron atoms.

I saw that the electrons in the iron atoms were resisting frantically at this moment.

"Well, I want to see what I can squeeze it into!"

The speed at which the pressure surged may have sensed Lu Xingchen's madness at this time, and the speed increased exponentially.

Looking at the wildly jumping numbers, Lu Xingchen's breathing began to get heavier.

It was another extremely long wait, with the pressure approaching one hundred trillion atmospheres!

Staring closely at these iron atoms, Lu Xingchen began to feel excited.

In the end, the iron atom finally gave in, and the powerful pressure directly pushed the iron atom's electrons into the nucleus.

These electrons cancel each other out with the positively charged protons to form neutrons.

At this time, a neutron star appeared in the device.

"Oh my god! Mom, I made it! I rubbed a neutron star out of my hand!"

At this moment, the system suddenly jumped out in fear.

The system directly projected three-dimensionally next to Lu Xingchen.

[“Stop it! Host, stop it! Stop it now!”]

Lu Xingchen was startled by the sudden sound and began to wake up.

"What's wrong, Dai Mei'er System? Why did you suddenly appear?"

[Host! You've already created a neutron star! If you continue like this, you'll lose control!]

"Why? Isn't your device invincible? I think it's fine and I can keep pressing!"

[Hey, host, wake up! After a certain period of time, the device's energy system will fail, and then the compressed matter will be discharged!]

"Huh? This device also has an energy system?"

[Right! Energy can't just appear out of thin air, right? If it can't be contained and released, it will be a catastrophe for the entire solar system!]

When Lu Xingchen heard this, he suddenly remembered.

"That's right! As soon as it comes out, it will start accreting like crazy, and when its mass exceeds the Oppenheimer limit, it will collapse into a black hole!"

At this moment, Lu Xingchen finally understood why the system had asked him to be cautious when rewarding him.

It turns out that the phrase "Don't rub a black hole when the time comes" is not a joke!

"Oh my goodness, what should I do now?"

At this moment, the system suddenly became cunning.

【What's wrong, host? Are you scared now? 】

"I can tell you the truth, you can definitely handle this tiny neutron star!"

"What? My body is actually this strong?"

[Yeah, actually, if you want, you can jump into a star without any problem!]

"Good man, what is this? Can I think of it as you giving me the body of an emperor?"

[Haha, I can understand that. After all, you're not C-136...]

"What? What did you say? Give me more details!"

[No...it's nothing. Anyway, your current body can actually be considered "invincible"!]

[It's just not time yet. Once you get the final body upgrade card, you'll know what true invincibility means!]

Lu Xingchen became a little angry when he heard this.

"Good fellow, what do you mean? Are you treating me like a tool?"
