After 9S came to the Honkai Impact Three Worlds, because he knew that Walter's ability was not mentioned in the plot, he only knew that the ability of the first law could control gravity and change his appearance, and by consulting the information and speculation of inverse entropy, 9S had a rough guess about Walter's ability as the first lawyer, that is, to manipulate gravitational waves.

At the beginning of the twentieth century, Albert Einstein predicted the existence of gravitational waves based on his discovery of the general theory of relativity, in physics, gravitational waves refer to ripples in the bending of space-time.

As we all know, we live in three-dimensional space, and one dimension is a straight line composed of countless points, with length, width and height; The two-dimensional is a surface composed of countless lines, with length and width, and no height; Three-dimensional, on the other hand, is a body composed of countless faces, with length, width, and height.

So if Walter can really manipulate gravitational waves, then he can create a four-dimensional space, and the difference between four-dimensional space and three-dimensional space is that four-dimensional space has one more thing on the basis of three-dimensional, and that is time.

At this time, you may ask, what is the relationship between the four-dimensional space and Walter Young's appearance?

Of course, it has a relationship, in three-dimensional space, the object we see is only a side of the four-dimensional, the present appearance of the object, and in the four-dimensional space, we can see the past and future of an object, this is the difference between the four dimensions, that is to say, the ability of the first law can theoretically turn himself into his past self or future self in the eyes of others, and the future is full of uncertainty, so Walter Young can instantly change countless different appearances based on his current appearance. But no matter how much Walter Young changes, there will always be a certain degree of similarity in appearance, so Sakuya can identify Walter Young.

Of course, the ability to manipulate gravitational waves is not only used for disguise, but its greatest ability is to allow the user to observe the past and future based on the timeline where the user is at this time, simply put, to predict the future.

From the information consulted in the inverse entropy, before 1955, the technology of the inverse entropy was far behind the Mandate of Heaven, and after that, the first lawyer Walter did not know where to bring back a large amount of scientific and technological information, so that the power of the inverse entropy developed rapidly, and in 2000, the technology of the inverse entropy had far exceeded the Mandate of Heaven, this information convinced 9S of his guess.

And this is only four-dimensional, four-dimensional is based on a timeline of the past and the future, the future will be different according to the choice of the present and produce different directions, if Walter can create a five-dimensional space, then he can observe countless different world lines, simply put, the four-dimensional Walter can know whether the last lawyer can destroy the current human civilization in the future, and the five-dimensional Walter can know what method to defeat the last lawyer, and even how to completely destroy the phenomenon of honkai. However, it is clear that Walter failed, and I don't know if it was because the core of the lawyer was not enough to create the five-dimensional space, and the forcible creation led to the death of the backlash, or because he was killed by the Honkai will of the creator of the law when he was observing the five-dimensional space.

9S thinks it should be the former, and the latter should have come to the door a long time ago, and there are also 9S people from another world, and if the Honkai will has its own consciousness, it is impossible to calm down.

"So...... All you have left now is the ability to control gravity and change your appearance? ”

9S said with a look of disappointment to Walter Young, who was sitting across from him.

"If I had Walter's abilities, I would have used them to find out who you are."

Walter Young spread his hands helplessly and said, if he could, he also wanted to have all Walter's abilities, but who knew that Walter was too desperate when he created the five-dimensional space, and he almost died on the spot at that time, not to mention, now he still needs to rely on absorbing his vitality to ensure that the core of the lawyer will not be further damaged, so that he only dares to use the ability to change his appearance now, and the ability to control gravity will not be used unless necessary, and he will vomit blood every time he uses it, as if he is ready to hang up at any time.

"Well, aside, since Walter's ability is really to control gravitational waves, do you know who the last lawyer is?"

9S asked curiously, in the Honkai II of the previous life, the last lawgiver was transformed by Kiana's blackening, but this is the world of Honkai Impact III, and it is hard to say who the last lawgiver is, after all, since Walter can see the future, why did the reverse entropy create the Moonlight Throne, and through this, the four Honkai gems in Kiana's body were reorganized into the core of the second lawyer.

"What do you want to do?"

Walter Young said as he stared nervously into 9S's eyes when he heard what 9S said.

"You'd better not think about that, do you think Walter didn't think of it in the first place? But every time he wanted to kill the last lawyer's body in advance, the four-dimensional space would tell him that after he did it, the last lawyer's body would awaken immediately, and then destroy the entire human civilization, Walter tried hundreds of different methods, and even used tactical nuclear bombs to bomb, but without exception, 'she' would wake up a moment before suffering a deadly attack, and then start to destroy human civilization. ”

Walter Young lay backwards and collapsed on the sofa, a breath of despair surrounding him.

"After absorbing Walter's memory, I also saw the scene of Walter observing the four-dimensional space at that time, you can't imagine what a desperate scene it was, Walter observed hundreds of different endings, and I also saw the last lawgiver wake up hundreds of times, and then use her invincible power to easily erase human civilization, even if the power of the second lawgiver is combined with the first law, I think it may not be able to compete with her, let alone defeat her...... But this is our last resort, and if we don't defeat the Last Lawgiver, our civilization is doomed to destruction. ”

"That's ......"

9S said with some pity, he still wants to ask Walter Young who the last lawyer is, and then go and see if he can kill it, anyway, he can read the file and start over, but since Walter has already tried, then he will not be bored to die, now he does not have the confidence to kill the last lawyer, to deal with the last lawyer, he has to rely on the research of Tipol and them.

"That ......"

As soon as the words were spoken, the pocket of the 9S shook wildly.

"Huh? Got it? ”

9S reached into his pocket.
