"Then there are differences and promotions of the world line, just like the plot development." Yu Shixiu explained seriously, "Suppose this chocolate is the food your girlfriend loves the most, and it is what she left for herself. If you eat the food she left for her, she will be very angry and slapped you in the face. This is a development direction, and it may be that you quarrel and finally break up. Or if you don't eat this chocolate and leave it for your girlfriend, she will not slap you in the face. Your development direction may be benign, step by step towards marriage. This is the parallel route caused by different choices. These two lines will not meet together. Then use them as the origin, because of the new differences, more parallel lines based on this may be generated, and go to completely different places."

"It's so complicated! But I understand a little." Qin Shou nodded, "It's like a branch is forked. Does the universe consist of countless parallel worlds?"

"I said it was a reason, but I haven't studied it, and I heard it was said by others." Yu Shixiu, "Maybe the whole reason is not true. Maybe we only have one universe and one world."

"Then you say that parallel worlds are going differently, so there should be no intersection." Qin Shou asked, "Is the same person on different world lines completely different two people, or is it just like looking in a mirror, just in different positions? Is it possible that the same person is in different worlds and even the name is different?"

Yu Shixiu thought for a while: "The origin is the same, which leads to different names."

"for example?"

"For example, your ancestor's surname is Qin. After a certain disagreement, he married his wife, gave birth to a child or had a surname Qin. Another disagreement is that he married into someone else's family, and the child took his wife's surname. It is also possible that the child was adopted by others and changed his surname directly. It has been passed down from generation to generation, and after various situations, it is possible that the two world lines are the same person, and it is possible that different surnames appear."

"Oh~" Qin Shou suddenly realized, "You said this, it's true! Oh, let me ask again. Is it possible for two parallel worlds to meet? What will happen if two self-meets meet?"

"Your questions are all very strange! What science fiction novels have you read? I have a lot of imagination?" Yu Shixiu looked confused.

"Let's talk! Maybe we can make a movie when we have time, so we can do this parallel world type." Qin Shou said with a smile.

Yu Shixiu replied helplessly: "The reason why it is a parallel world means that it is always parallel and has no interception. How can two parallel worlds intersect? Even if it is inference, it is impossible!"

"If so! If this happens, what will it look like?"

"What if two parallel worlds intersect?" Yu Shixiu scratched his head, had a headache, dipped his fingers in tea, and drew two parallel lines on the table. "They were originally parallel, and there was only one way to intersect!"

"What's the solution?" Qin Shou stared at his hands.

Yu Shixiu suddenly tilted down from one of the lines and connected the two parallel lines together: "The two lines are connected together, and there may be interleaved, with only one brief connection, or it may be possible to generate a new world line after the connection. If it is just a cross, the impact will not be great, and they will return to the parallel state. If a new world line is generated, a brand new plot will be generated from the connection point."

"What will happen if a new world line is created and two people meet in this world line?" Qin Shou asked hurriedly.

"Generally speaking, you can't meet yourself in a parallel world."

"Why?"

"Because when the world line is connected, you in the two worlds are actually the same person, just like this intersection point overlaps." Yu Shixiu pointed to the waterline on the desktop and said, "In this world you are yourself, and in a parallel world you are yourself, you are you. Once the two worlds overlap, there can only be one you, otherwise it will be a paradox! If you are not you, how can you have another parallel world that has you?"

"Oh~ So when the same person meets, the other person will definitely disappear?"

"Maybe a person appears, the other person disappears, or the person disappears, leaving the other person. Another possibility is that the two are as integrated as the world line, because they are the same person!"

Hearing this, Qin Shou couldn't help but think of the "self" who turned into a zombie. At that time, he turned into a light spot and merged into his body, which was extremely consistent with Yu Shixiu. Thinking of those strange phenomena, he quickly asked: "Minister Yu, if the parallel world merges with the same person, will this person's identity change? Will the memory be shared, will the life experience be shared? If it changes, who will change who?"

"Your question is beyond the scope of what I can answer!" Yu Shixiu looked speechless, "I haven't studied these things, there is no such example in the whole world. How to answer it?"

"You just try to answer it from a scientific perspective and use inference?"

"Science...inference..." Yu Shixiu hugged his head and thought for a long time, and finally said, "I think that once the two world lines are merged, there will definitely be changes. After the integration, they are obviously the same person, but they have different identities and memories. When they arrive at a new world line, will they be repaired by this world line and become compatible? Otherwise, it is also a paradox. They are obviously the same person, because there are differences in the world line. When they appear in the same world line, you must be you, and it cannot be others. But you must also be him. Under such contradictions, unless you can neutralize it, let you be yourself, he is himself, and then you are him, he is you."

"Where are you talking about tongue twisters here?"

"I said that I was not studying this, which made me a little dizzy!" Yu Shixiu felt a headache. "To be honest, do you really have the superpowers to travel through the world? Otherwise, I would suddenly ask these questions? You can almost do everything, and it is not surprising to master such abilities. If it is true, why not study together? Our scientific research department will definitely do its best."

"You're thinking too much!" Qin Shou shrugged, "I really have the ability to travel through time. I will bring everyone to a safe world without having to deal with zombies. It's just random thoughts!"

"Okay! If one day you really awaken this ability, or have other strange abilities, you can contact our scientific research department and we interpret it scientifically. In fact, can your current superpowers be tested by our scientific research department? Maybe it can benefit mankind and make more survivors the chosen ones..."
