Hearing Ji Ran's explanation, Liu Zhan suddenly came over, it turned out that the story about Li Han that Ji Ran had told her before was not a joke, but a real existence.

In other words, human beings in the future can travel between the past and the future through super-space-time transmission, but they are limited by the existence of super-space-time transmission protocols, so they cannot casually travel from the future to the past and change history.

Although Liu Zhan couldn't understand why others couldn't cross over, Li Han could cross back again and again? What makes Liu Zhan even more incomprehensible is that according to the provisions of the future super-space-time transmission protocol, no one can change the past history, let alone bring things that do not belong to history back to history, for example, you can't travel back to the Qin Dynasty with an atomic bomb, if that's the case, if you throw a nuclear bomb at Xianyang, Qin Shi Huang will burp, and you still need Jing Ke to assassinate the King of Qin?

For another example, if you go back in time and kill your unmarried grandmother, then you don't have your own father, and without your father, you don't have yourself, and how did you go back in time and kill your grandmother?

Of course, this grandmother paradox has long been confirmed and does not exist, because in superstring theory, in our world, there are countless parallel universes, each of which represents an infinite number of possible existences with the same starting point, that is, these countless parallel universes all originated from the Big Bang with the same singularity, but after the Big Bang, there will be countless possibilities in the long evolution of the universe, and each possibility will give rise to a new universe.

For example, a person goes on a blind date and meets a beautiful little girl, and then he confesses to the little girl, at this time, there will be two results, one result is that the little girl agrees to the young man's marriage proposal, and the two become lovers, and the other result is that the little girl rejects him, and finally the two people return to their respective lives, and before the little girl answers the young man's courtship, the two people are in a common universe, and when the little girl gives the answer, the universe is divided into two parallel universes.

In a universe, the young man chased his beloved girl.

In another parallel universe, the young man was rejected.

Therefore, in parallel universes, every time you encounter a choice, a new universe will be derived.

Going back to the grandmother's paradox, a young man wants to go back in time and kill his unmarried grandmother, at this time, when he goes back in time and raises his pistol at his grandmother, he will face two results, one is that he shoots and kills his grandmother, and the other is that he doesn't shoot and his grandmother is still alive, and these two possibilities will give rise to two parallel universes.

In one universe, the young man killed his grandmother, and then, when the grandmother died, the young man ceased to exist, and the universe was annihilated.

In another universe, the young man did not shoot his grandmother, and then, there would be no contradiction of the grandmother's paradox, and that universe still exists in an orderly manner.

After understanding the above theory, you can know that if you go back to the past at will and change the orderly world, it will bring a lot of trouble, so the Chrono Protocol will stipulate that it is not allowed to travel to the past casually and change history.

And Li Han has traveled from the future to the present more than once, and has helped Ji Ran more than once and changed history, why can she do it?

Is it the poor management of the future Chrono Authority?

Or is there another reason?

This question is not only incomprehensible to Liu Zhan, but also incomprehensible to Ji Ran, in short, since Li Han appeared, his world has changed.

If Li Han hadn't appeared, maybe Ji Ran would have been succeeded by Ma Kai on that afternoon two years ago, maybe Ma Kai would have been arrested and imprisoned as a sword snatcher, or maybe Ji Ran couldn't bear to ruin Ma Kai's future and committed himself to marrying him, in short, if Li Han hadn't appeared at that time, Ji Ran's life might have changed long ago.

Li Han changed Ji Ran's life, and the universe also changed.

And now Li Han has given Ji Ran a super invincible, at least in the eyes of this era, it is an incomparably powerful portable system, which will undoubtedly greatly change history and change the world.

"Forget it, let's go to the house first." Ji Ran and Liu Zhan returned to the cave and asked Ji's father and Ji's mother to go to the stone house to take shelter from the rain.

Ji's father and Ji's mother came to the stone house, stunned and stunned, they couldn't understand why a beautiful stone house appeared here out of thin air, it looked very sturdy, I'm afraid that even if the materials are prepared, it can't be built in three or five days, right?

"Yet, what's going on with this house?" Mother Ji asked in surprise.

"Mom, don't ask, as long as you live comfortably." Ji Ran said with a smile.

Ji's mother and Ji's father looked at each other awkwardly, but they were full of curiosity about this stone house that suddenly appeared.

Dad Ji reached out and touched the wall of the stone house, the stone on this wall was still polished, it was very textured to the touch, and it was very hard and strong, and you could even see the texture and details on it.

"Well, where did you get these stones? I've searched all the mountains around here, but I've never seen this kind of granite. Father Ji touched the granite on the wall, looked at Ji Ran and asked.

"Dad, don't ask, in short, it's good that you two elders live happily." Ji Ran wiped his hair with a towel and said with a smile.

"This house is good, but there is no furniture and no bed, where will I sleep this night?" Ji's mother looked at the house, it was quite spacious and sturdy, and the only fly in the ointment was that there was no furniture.

"Well, I'd like to figure it out." When Ji Ran heard the problem pointed out by her mother, she immediately opened the system panel, and she looked it up in the points exchange area.

Soon, I found an exchange interface for furniture and the like.

A double bed with hedgehog rosewood can be redeemed for only two points, and a set of solid wood leather sofas in red walnut can be redeemed for only three points.

Ji Ran quickly exchanged for a double bed of hedgehog red sandalwood and placed it in the room of Ji's father and Ji's mother.

Ji Ran immediately exchanged for a set of red walnut solid wood leather sofas and placed them in the living room.

Ji's father and mother looked at the sofa that suddenly appeared, and they were stunned in surprise, and their jaws were about to fall to the ground.

Because they just saw that Ji Ran just casually stretched out his hand and pointed, and the sofa fell in the living room, which was like a trick, which made them sincerely frightened, surprised and happy.
