Life in the collapsed world from scratch

"Yes, I'm sorry..." Agreement whispered weakly, covering his head.

Fortunately, at least I know how to apologize and correct my mistakes.

Cheng Xi thought to himself, and just as he was about to help the girl rub her painful spot, he heard her continue to say:

"Then let's not do the experiment, let's just get started?"

Cheng Xi: "...?"

What about paying homage?

"Huh? Do you mean watching the stars?" Li Zhi tilted his head and said nonchalantly, "It's okay, I'll apologize to her later."

Is this something that an apology can fix?

Sure enough, there is indeed a big problem with this Herrscher's three views... It should be said that if she is not in charge, if she is allowed to mess around, the world will be messed up sooner or later, right?

Cheng Xi felt that the burden on his shoulders was a little heavier.

"However, Cheng Xi, why do you suddenly start to care about this kind of thing?"

Restriction looked at him suspiciously and asked, "It's almost like arranging funeral arrangements."

Cheng Xi: "..."

Although there are indeed considerations in that regard, can you please change the term? .

Chapter 490 How to defend better?Of course, it is to increase the lethality as much as possible!

Cheng Xi already knew that it was unreliable to seek restraint to discuss this kind of matter.I hoped that she would be serious, but it turned out that there was nothing wrong with her mind.

In other words, when I first saw Constraint, I felt that she was quite normal, how did she become like this.

Or, did it really come from a performance at that time?

"So, you thought of me~ didn't you?"

Guan Xing sitting opposite took a sip of coffee and frowned slightly, as if he was not used to this kind of taste.

"Because Guanxing, you are the most reliable person around me." Cheng Xi didn't hesitate to praise her.

In fact, he did think so.It's just that it was a simple meeting at first, but because of what Li Zhi said before, he always felt a little weird when facing the stargazing.

"Such empty compliments can be avoided." The girl replied like this, she didn't seem to buy it very much, but from the corners of her mouth slightly raised, it can be seen that she is actually in a good mood.

"Cough... so, what do you want me to do?"

I can't find you if I have nothing to do... Although I want to say this, but after all, I really have something serious to do, so Cheng Xi won't interrupt me.

He pulled out a crack from the void around him, took out a box from it and put it in front of the stargazer.

"I want to entrust this to you."

"...What is this?" Looking at the plain, even worn-out box in front of him, Guan Xing asked suspiciously.

"Humanity's final defense measure." Cheng Xi replied seriously.

"?"

"You mean...cookies?"

Looking at the biscuit label on the box, Guan Xing asked with some uncertainty.

"This, it's just that I didn't find a box of the right size..."

It just so happened that Xiao Cangxuan bought a box of biscuits and was forcibly requisitioned by him.She seemed to like this box quite a bit, and she was unwilling to talk to herself for two or three days after this incident.

However, these are not the point.

"The packaging is not important, what's inside is what matters."

"So, it contains what you said... the final defense measures for human beings?" the girl asked.

"To be precise, it's the final defense three-piece set...it's a three-in-one gift box."

"Really?" Stargazing glanced at the four blue cubes in the box, with a hint of doubt in his eyes.

However, what I saw were four "small boxes"?

"One of them is a combination pack."

Cheng Xi took out two of the cubes and put them aside, looked at the stargazer and said, "You know, although I have always believed that the Final Herrscher who destroyed the civilization of the previous generation is not an invincible final enemy, but There is nothing less to prepare for.”

The so-called despise the enemy strategically and pay attention to the enemy tactically is probably what it means.

Guan Xing nodded lightly: "I know, and... "Magic Wolf Fenrir" was created by you in the first place to deal with the final Herrscher, right? "

The final model of the imitation star series, with the Star of Eden as the core, combined with the full output of the Moonlight Throne, at the cost of half the moon's mass, is a god-killing weapon with only one chance. The craziest weapon ever conceived by the Last Herrscher.

· · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·?

Although now with the help of restraint, if you want to use this weapon, it is obviously much more convenient than before.

but……

"I heard that that weapon should have been eliminated and sealed up." Guan Xing asked aloud.

Cheng Xi nodded lightly: "The reason for elimination is of course because there are better and more lethal weapons."

 …  

In his mouth, the weapon that is more lethal than the "Magic Wolf Fenrir" that can burn through the entire earth, are these four small cubes packed in a biscuit box?

Stargazer was even more puzzled.

It's not that she doesn't believe in Cheng Xi, it's just that she recalled the floating battleship that was as big as an aircraft carrier, and then looked at the small cube that could be held with one hand. The strong contrast between the two made her feel Some violations.

What's in it?It can't be antimatter, can it?

"That's not true." Cheng Xi shook his head lightly and gave a negative answer.

"But it is indeed a way of thinking."

Instead of relying on the energy produced after annihilation, but relying on the rule that positive and antimatter will annihilate each other, it may also cause some damage to the other party.

While thinking this way in his heart, Cheng Xi raised his head to look at the girl across from him, paused for a moment and asked, "Stargazing, have you heard of the neutron star?"

Chapter 490 The most dangerous substance under the laws of physics

If we said that during the bubble period of the world, we did not understand it due to the limitation of the times, then after coming to this world and being exposed to so much knowledge, stargazing is impossible for the "neutron star", a well-known celestial body in the universe and astronomy I no longer know.

"As we all know, the reason why a neutron star is called a neutron star is because its own mass is too large, so that under the action of huge gravitational force, the atoms can no longer maintain their complete structure, and the degeneracy of the electrons is unable to maintain support, and the electrons are pressed into the Into the nucleus and combined with protons into neutrons, so that the whole planet eventually becomes a celestial body composed only of neutrons."

After briefly introducing the concept of a neutron star, Cheng Xi continued: "In the previous theories, we usually believed that the mass of a celestial body would increase by "[-]", and its gravitational force would be so strong that even neutron degeneracy pressure would not be able to withstand it. If maintained, the neutron star will collapse further, collapsing into an all-consuming black hole."

"But now we all know that neutrons and protons are not the basic forms of matter... Between black holes and neutron stars, theoretically there is still a 'quark star' that is made up of quark soup after neutrons are crushed ' That's right."

Neutrons are not the fundamental particles of matter, but are composed of smaller quarks, which is a fact recognized by the physics community today.

In physics, quarks cannot exist alone, but are constrained into a bound state by an effect called "quark confinement".To put it simply, the more you try to pull them apart, the stronger the "attraction" between them will become. Even if there is any energy that can break through the critical value to force them apart, they will use this energy to separate them. Create new quarks to maintain a stable bound state.

As a result, quarks only co-exist in the building blocks of other particles, and have never been observed individually.

There are many types of them, but only two of them can produce stable matter, which are named "up quark" and "down quark". For example, neutrons are composed of two down quarks and one up quark.

Other quarks, on the other hand, seem to decay rapidly.

But inside a neutron star, the situation may be different.

In the extreme environment of terrifying ultra-high pressure and ultra-high temperature close to the beginning of the Big Bang, the bound state of protons and neutrons may be released, and countless particles will be squeezed and dissolved to become a kind of pure quark. Quark matter.

A celestial body with this kind of matter as its core is called a quark star.

"But if the pressure inside the quark star is high enough, it is possible for the up quark and the down quark to collide, thereby producing another particle called a strange quark that is heavier than the up and down quarks." Cheng Xi explained road.

"And the nucleons composed of strange quarks and up and down quarks are substances called strange quark clusters."

Stargazer nodded slightly.

She doesn't know much about high-energy physics, but she has generally heard of such a theory.

"The next step is the key." Seeing that the girl had no doubts, Cheng Xi continued to explain without pausing.

"Strange quarks have weird nuclear energy properties. They can be regarded as the most stable and perfect matter in the universe, which allows them to exist independently of the environment of neutron stars. At the same time, because the density and stability of strange quark clusters far exceed that of protons And neutrons, they will tear the protons and neutrons close to them, release energy, and then form more strange quark clusters through the above process."

Hearing this, Guan Xing probably knew what Cheng Xi was going to say.

"You mean..."

"That's right." Cheng Xi nodded slightly, and said with a smile: "This also means that as long as it is contaminated with a little bit, even if it is just a subatomic strange quark, its 'infectiousness' is enough to make the whole contact objects until it is transformed into the same form.”

It doesn't matter whether the opponent is life or non-life, organic or inorganic, high-dimensional or low-dimensional, and no matter how huge the existence of the opponent is, it doesn't matter even if it faces a whole star, as long as there is a material basis, strange quarks will transform it equally . . .

If the earth touches it, it will become a celestial body the size of an asteroid. If the sun touches it, it will also be collapsed into a strange star. As for low-entropy life forms?The result is of course self-evident.

Theoretically, the conditions for the birth of this extremely dangerous substance are extremely harsh, but since Cheng Xi said so, it also means...

"That's right." Cheng Xi nodded, looked at one of the small cubes on the table and said, "Although it's only a little bit, we did prepare it."

It should be said that if the properties of strange matter are really as Cheng Xi said, then there is no difference between "a little bit" and "a lot", right?

With the help of the Herrscher's ability to break the rules of physics, although it took a lot of effort, after all, even black holes can be rubbed with hands. This is not something that cannot be done theoretically.

However, because it is similar to antimatter, but infinitely more dangerous than antimatter, so after it is manufactured, for insurance, it can only be contained and restrained in the empty space itself.

"What did you say that "Fenrir" is too risky... Isn't this infinitely more dangerous than that? "

Even stargazing, I can't help but want to complain at this time.

You also call this 5.5 "defense"?

Moreover, such an extremely dangerous "defense" method, if not counting "Magic Wolf Fenrir", he still has three... no, two.

The gaze of the stargazer fell on the other three small cubes on the table.

"Not really. If it is used to deal with the Herrscher, there is only one backup plan." Cheng Xi shook his head and said.

"Eh?" Guan Xing was slightly taken aback.

However, there are two groups...

"Because of this group..." Before she could ask a question, Cheng Xi's eyes fell on the blue cubes of the remaining two "combination sets", and she answered aloud:

"It was used to deal with the real god.".
