After half a pillar of incense, Xiang Luyang was finally freed from the pain, and during this half-pillar of incense, Xiang Luyang felt as if he was in hell, walking back and forth.

Seeing that Xiang Luyang had survived this hurdle, Lan Qinghai spoke: "I have already helped you complete the washing of the scriptures and marrow, and how far you can go in the future depends on your creation." ”

Xiang Luyang asked puzzledly: "I don't quite understand what you mean by washing the scriptures and cutting the marrow. ”

Lan Qinghai said lightly: "When I checked your memory just now, I found that there is this word in your memory, and this word can well interpret the process just now, I thought you would understand." ”

Xiang Luyang said: "Of course I understand it, but it is just the world I used to live in, and the fictional episodes in the novel are not real." ”

Lan Qinghai smiled and said, "Didn't you just experience it, how could it not be real?" ”

Xiang Luyang said: "You mean, I can now start cultivating immortals like those people in the novel, after washing the scriptures and cutting the marrow?" ”

Lan Qinghai said: "Cultivating immortals is just the name of your world. ”

Xiang Luyang said: "It doesn't matter what it is called, I want to know now, whether I understand it correctly!" ”

"Yes!" Lan Qinghai said affirmatively.

Xiang Luyang took a deep breath and calmed down his somewhat excited mood, "Who are you?" How did you do that? ”

Lan Qinghai said: "If you have nothing to do, I'll tell you about my past, this story is very long, if you want to hear it, let's go over there and sit and talk slowly." ”

Xiang Luyang and Lan Qinghai came to the depths of the cave, and after the two sat down, Lan Qinghai began to tell a story about him.

"My name is Lan Qinghai, and I, like you, don't belong to this world."

Xiang Luyang said in surprise: "You also crossed over?" ”

Lan Qinghai said: "It can be understood in this way, in fact, the crossing in your mouth is just a normal shuttle in the parallel world, in the world we live in, this kind of thing is very common." ”

Xiang Luyang repeated: "Parallel world, normal shuttle, very ordinary? ”

Lan Qinghai said: "Yes, in our world, as long as people cultivate to a certain extent, they can travel back and forth in various parallel worlds without the limitations of time and space, which is what you call traversing. ”

Xiang Luyang interrupted Lan Qinghai's words and said, "The parallel world you are talking about, is it also the vocabulary I know from memory?" ”

Lan Qinghai nodded and said, "All the words I use are words that you can understand. ”

Xiang Luyang said: "But the word parallel world, I only know a general concept, can you explain it in detail." ”

Lan Qinghai thought for a moment and said: "To put it simply, parallel worlds are different spaces on the same time axis, these spaces, everything that happens, only belong to the world they are in, and all things, although they have a certain connection, do not interfere with each other. ”

"Just like the world you lived in before, the world I lived in, and the world we live in now, they all have a certain connection with each other, but what happens between them is independent and not related."

Xiang Luyang said: "You wait first, do you mean that what happened in this era has nothing to do with my original era?" ”

Lan Qinghai said: "Yes, you did not return to your past, but came to your world, neighbors in the parallel world, although these two worlds seem to be causally related, but in fact, these two worlds are just two separate individuals that exist in parallel, no matter what you do or do in this world, it will not affect the world you originally lived in." ”

Xiang Luyang said: "I doubt your theory, although you can do it, it doesn't mean that you know everything. ”

Lan Qinghai smiled and said, "You suspect it, it's because you haven't experienced it, do you remember the discussion about this planet in that half of the longevity recipe?" ”

Xiang Luyang said: "Remember! ”

Lan Qinghai said: "In the world you lived in, people already have a certain understanding of the planet and the universe, although it is very shallow, but it can be regarded as a first glimpse of the doorway. ”

"According to your understanding, the earth is your living space, and the reason why he can exist is completely dependent on the sun, so that is to say, the solar system is your real home, but do you know how many solar systems there are in the Milky Way? Do you know how many galaxies there are in the universe? Do you know how many universes there are? ”

Lan Qinghai's series of questions made Xiang Luyang completely speechless, he is a special soldier, not an astrologist, and he only knows the knowledge claimed by the mainstream media about the space in which he lives, but this knowledge can't answer Lan Qinghai's questions at all.

Seeing that Xiang Luyang didn't speak, Lan Qinghai continued: "Within the scope of the universe you know, how big is the position of the planet you live in in the universe? ”

"If the universe is compared to a person, then the earth is not even a hair, at best it is just a speck of dust."

"Can you guarantee that all the dust on your body is different?"

Xiang Luyang shook his head.

Lan Qinghai continued: "In fact, the parallel world is the abbreviation of these same planets in different positions, these planets have evolved fast and slow for some reasons, but the general progress will not be too different, just as the world we are in now is the so-called Ming Dynasty of your world, but this Ming Dynasty is the Ming Dynasty of another planet, not the Ming Dynasty of your planet, but this planet, the speed of evolution, is only a few hundred years slower than yours. ”

As soon as Lan Qinghai's voice fell, Xiang Luyang couldn't wait to ask: "Do you mean to say that on the same time axis, there are many earths, and parallel worlds have formed between them, and our so-called crossing is just an interstellar trip to another identical earth?" ”

Lan Qinghai said: "Do you understand what a parallel world is now?" ”

Xiang Luyang nodded noncommittally, and then spoke: "You mean to say that all the earths on this timeline are evolving according to certain laws, but for some reason, the process of evolution is fast and slow, but the people and things in it are all the same?" ”

Lan Qinghai shook his head and said, "It turned out to be, but now it's not." ”

Xiang Luyang was puzzled and said, "Why? ”

Lan Qinghai said: "This is an inevitable reflection of the middle stage of evolution. ”
