"Four-phase bomb?" Chiyo wondered, "What's that?"

"Sit down and talk, do you two want to eat something and talk while eating?" Mr. Xun said, "It's a bit unreasonable for five people to stand here and talk." ”

Yu Zecheng nodded, and sat on the sofa on the second floor of Mr. Xun's house with Xiao Qianyo, Wei Shengnan and Huang Yanbo then sat down, and Mr. Xun went downstairs and quickly brought the fruit bowl up.

"Eat, you're welcome. Mr. Xun greeted.

Except for Wei Shengnan, everyone picked up a piece of fruit, Yu Zecheng ate very slowly, Xiao Chiyo took a small bite while glancing at Yu Zecheng with the rest of her eyes, it seemed that she still cared about Yu Zecheng's emotions.

Seeing that Wei Shengnan didn't move the fruit, Mr. Xun picked up a piece and handed it over, Wei Shengnan took the fruit but didn't take a bite for a long time, his eyes showed a hint of rejection, not because he was angry or deliberately losing weight or anything, but the kind of look that really didn't have any interest in fruit.

Mr. Xun was the first to finish eating the fruit, and when he saw that everyone had no intention of talking, he took out a tissue on the table and wiped his hands and said, "Then I'll help Xiao Chiyo explain what a four-phase bullet is." ”

"The atomic theory was verified in the middle of the twentieth century and developed very rapidly, so it was born from the basic atomic theory, and in just a dozen years there was a model of a three-phase bomb. ”

"What is a three-phase bomb?" said Chiyo with a wink. Her eyelashes became long and charming after gaining Tomie's ability, and judging from her appearance alone, Xiao Chiyo's appearance was already on par with Wei Shengnan and Huang Yanbo, and even far surpassed Wei Huang's second daughter in terms of femininity.

"The so-called three-phase bomb simply means that an ordinary hydrogen bomb is covered with a layer of depleted uranium (uranium-238) material. Although uranium-238, a cheap material used in tank armor and armor-piercing shells, is very safe in peacetime, when a hydrogen bomb undergoes nuclear fusion, a large number of high-energy neutrons will be produced, and the uranium nucleus of uranium-238 will cause fission, producing energy and fission neutrons, the former enhancing the killing power, and the latter in turn impacting the lithium-6 material in the hydrogen bomb, creating a new tritium, intensifying a new round of thermonuclear fusion, and the next virtuous cycle is needless to say. It can be seen that its principle is three processes: nuclear fission, nuclear fusion, and nuclear fission, so it is called a three-phase bomb. It multiplies the power of ordinary two-phase shells. ”

"So the hydrogen bomb is equivalent to a two-phase bomb?" said Chiyo.

"That's right. Mr. Xun continued: "Three-phase bombs produce more radiation and depleted uranium fragments, and their explosive power is several orders higher than that of hydrogen bombs. Then, on the basis of the three-phase bomb, add a layer of thermonuclear reaction raw materials to its outer layer, so that the extreme temperature and pressure generated when the three-phase bomb explodes catalyzes the outermost thermonuclear material, and this is the four-phase bomb. ”

"Isn't that the equivalent of nuclear fusion in the three processes of nuclear fission, nuclear fusion, and nuclear fission? She spent a long time with Professor Edward Taylor in the play, and she knew a little bit about the physics of atoms.

"Haha, here's the awesome part, generally speaking, thermonuclear materials are deuterium or tritium and other substances, but at the end of the script, the little boy atom, oh no, the outermost thermonuclear material of the four-phase bomb is +5 and +6 of the superheavy iron, that is, Fe59 and Fe60, iron is theoretically the limit of thermonuclear reactions, only the power of the three-phase bomb can prompt it to re-engage in fusion reactions, and the material produced after the upheaval is by no means a more expensive element, but a terrible interstellar isotope, which produces enough power to shake the bottom shell and even destroy the continental plate. ”

"So...... Did the explosion of the little boy's four-phase bomb destroy the entire island country in an instant?!So at the moment of its explosion, our main mission, the extermination of the island country, was completed......" Xiao Chiyo said "we", and looked at Yu Zecheng cautiously.

"Yes, no matter how the four words of extermination of the island nation are defined, if the island country is completely erased from the map by physical means, the task will definitely be completed, but it will ......" Mr. Xun wanted to say and stopped.

"It's just that the consequences of that are unpredictable, and if the power of the four-phase bomb shakes the continental crust, I'm afraid it will shake the foundation of the earth in that script universe, and I don't want to make such a decision unless it happens. Yu Zecheng said.

"Wait. Chiyo said: "Although I can understand the principle of the four-phase bomb, isn't it just the time in the script that the technology to make an atomic bomb has just been reached? How can a hydrogen bomb be built so quickly to produce a three-phase bomb, not to mention the +6 valence iron element required for a four-phase bomb." ”

Yu Zecheng said: "As early as 1942, in the process of developing the atomic bomb by American scientists, some visionaries deduced that the energy provided by the atomic bomb explosion could ignite the hydrogen nucleus and cause a fusion reaction, and wanted to use it to create a super bomb with greater power than the atomic bomb. Although it was not until 1 November 1952 that the United States conducted the world's first test of the principle of the hydrogen bomb, the process from the atomic bomb to the hydrogen bomb was not complicated, and it was only necessary to provide some ready-made experimental data to those senior physicists, and it was not impossible for the hydrogen bomb to be born together with the atomic bomb. ”

"It turns out that in order to delay the development of the atomic bomb after Oppenheimer's arrest, you asked me to provide Taylor with the reference data in addition to the data of the atomic bomb, as well as the theoretical data of the four-phase bomb!"

Seeing that Yu Zecheng was silent, Xiao Chiyo said again: "That's not right, how did the 6-valent super-heavy iron required for the four-phase bomb come from? ”

"The data I provided to Taylor through you is only the data of the three-phase bomb, Taylor secretly reported to the American high-level after getting the data I provided, and his superiors agreed to thermonuclear modification of the atomic bomb, that is, the little boy atomic bomb is only a three-phase bomb, and the outermost layer of material is just ordinary iron, but at the end of the script, in order to deal with emergencies, through the ability to conserve mass and will, the outermost ordinary iron of the little boy's three-phase bomb was remotely turned into a super-heavy iron element, so the little boy's three-phase bomb became a four-phase bomb at the moment of the final explosion。 "Yu Ze became enlightened.

Xiao Chiyo was silent, she knew that the "emergency" in Yu Zecheng's mouth was referring to the phone call at the last moment.

"That's not right either. Huang Yanbo suddenly spoke, she looked at Yu Zecheng and said: "Your ability to conserve mass is only the third level, the Deerta level, even if the ability type is very compatible, it is impossible to make ordinary iron become the extreme element of the thermonuclear reaction of 6-valent iron at such a distance." ”

"Yes, I can't do it, but in that phone call with Kochiyo at the end of the script, Kochiyo's rampage of spiritual power affected me at the level of consciousness, as the saying goes, it is a mountain stone that can attack jade, even if my ability does not reach that height, but as long as I see that height clearly, I can imitate that height in a short time. Yu Zecheng sighed and said.

"So, do you want to continue the challenge of the Rebirth Script?" said Mr. Xun.

"That question is put aside. Yu Zecheng said: "I have a lot of questions at the moment. ”

Mr. Xun: For example?

Yu Zecheng: Is the rebirth script really just the so-called "script"?

Mr. Xun: Otherwise?

Yu Zecheng: I think... The so-called script worlds are real parallel universes.

Mr. Xun: Yes and what?

"How about it?" Yu Zecheng said: "What do you think of eating a four-phase bomb at your home and on the planet where you live?" The so-called war is just an indispensable behavior in the course of human history, whether the perceptual war is right or wrong, civilized or cruel, this is an unchangeable objective law, as a reborn to influence and affect its process, it is nothing, but for the so-called script task, to use such a thing as a four-phase bomb, causing hundreds of millions of deaths, is this really right?"

Mr. Xun smiled: "What are you talking about, aren't you the one who turned the three-phase bullet into a four-phase bomb at the last moment?" ”

Yu Zecheng: That's why I want to know everything about the rebirth script! I want to know what the meaning of what I am doing? If there really are countless parallel universes, and every world, and every possibility will become inevitable, what am I doing at present, and what is the purpose of struggling in the script world? The future of the continent, Chiyo-chan's parents, these ideals and aspirations can be found in the most ideal situation in the parallel universe, isn't it?

Mr. Xun sighed and said, "yes, what's the point? Isn't it just that I send you two to the universe where you can best solve your life? ”

Yu Zecheng: Why?

Mr. Xun said: "Although I have always been honest with people, now is not the time to tell you the answer to this question. ”

Yu Zecheng: Then when can you say?

Mr. Xun: When you continue to complete the rebirth script and finally achieve your mission, the same thing I want to say to Chiyo-chan.

Yu Zecheng frowned and said, "What if I don't?"

Mr. Xun: Participation in the Rebirth Script is free, and if you don't want to, I'll send you back to the universe before you participated in the Rebirth Script, and you can continue your life as if nothing happened. Of course, the abilities and skills acquired in the script can also be retained.

Yu Zecheng was silent after hearing this, and after a long time, he raised his head and looked at Xiao Chiyo.

Xiao Chiyo, who noticed Yu Zecheng's gaze, said firmly: "Uncle Zecheng, I want to continue." ”

Yu Zecheng sighed and said, "Give me a brief introduction to the next script, and I'll see you in a month." ”

Mr. Xun said: "This is my home, I came here to help Chiyo completely cure her illness, it's time to send off guests, so where do you want to go now?

Chiyomichi Kochiyo: Is there a choice?

Mr. Xun: The universe you two were born into is the main universe for you, so of course you can go.

Xiao Chiyo looked at Yu Zechengdao: Uncle Zecheng, I want to go back to the place where I was born.

Yu Zecheng nodded in agreement, Mr. Xun snapped his fingers, and Yu Zecheng and Xiao Chiyo's bodies gradually disappeared into the diamond-shaped light.

After the light faded, Yu Zecheng and Chiyo appeared in Chiyo's house, the bedroom where the second play "Loving Heart" began.

A small sofa in the bedroom sits a book.

The title of the script is "Double Kill".
