When Duan Pingsi was reading and studying alone in the dormitory, Bai Mao happily played on his desk, and he got along well with one person and one mouse, and Bai Mao never interrupted his train of thought.

Today is the weekend, Duan Pingsi is reading a popular science book called "Parallel Universe", and now he is just starting out in physics, and he can't understand more professional books yet.

Still, many of these problems stumped him, which forced him to turn to someone else.

Xiaoqiang welcomed Duan Pingsi's visit very much, and today he happened to be reading a book in the dormitory, and the two of them sat at the desk and chatted about the topic of parallel universes.

"I wonder how you understand parallel universes as a student majoring in this area?" Duan Pingsi first opened the conversation box and asked.

"In fact, the concept of parallel universes comes from the uncertainty principle of quanta, and scientists find that their states are different every time they observe quanta, and the universe is made up of these quanta, so scientists wonder if there are many corresponding universes since quanta have different states......

Xiao Qiang could talk endlessly, and he spent a total of two hours telling Duan Pingsi in detail about the ins and outs of the parallel universe, which benefited the latter a lot.

Duan Pingsi couldn't help but wonder if the place where the ancestor was located was also a parallel universe, whether there were rules of time and space that were different from those here, and whether the two were occasionally connected but could never intersect.

"Isn't it true that the ancestor will never come back, he is alone in a single cosmic space-time, he must be lonely, right?" Duan Pingsi muttered.

"What did you say?" Xiao Qiang saw Duan Pingsi's mouth open and closed, and thought he was talking to himself.

"Nothing, let's continue!"

Duan Pingsi smiled, quickly diverted his attention, and asked Xiaoqiang, "Is it possible for us to fall into another parallel universe?" ”

"The theory has not yet been studied to that extent, but it can be proved that parallel universes will collide with each other, and our universe has been collided at least four times, so it is not impossible to fall into another universe.

In addition, some scientists believe that the different outcomes of an event lead to the creation of parallel universes, in the sense that we are falling into different universes anytime and anywhere......"

Xiaoqiang explained that just like Schrödinger's cat, dead cats exist in one universe, but live cats exist in parallel universes at the same time, and there may be an immortal cat in another universe.

"Does that mean these parallel universes could be the same big?"

Duan Pingsi had doubts about the "universe" where the ancestor was located, maybe it was not a universe, maybe it was just an independent space-time, as he thought at the beginning, it was a bubble of time.

Xiao Qiang smiled awkwardly: "Your idea is very interesting, but we can't be sure of the size of our current universe, so we can't know the size of the parallel universe, maybe big, maybe small, this is beyond the scope of what I know!" ”

"You're already very good, I still don't know anything about it!" Duan Ping said.

In the slow contact with Xiaoqiang, Duan Pingsi learned that he was actually an orphan, who had lived in a welfare home since he was a child, and no one was willing to adopt him until he graduated from college.

But Xiaoqiang is really the unbeatable Xiaoqiang, he finally got the opportunity to study in China with his own efforts, he is far away from home just hoping to forget everything there, because where, he has been discriminated against because of his skin color and identity as an orphan.

Xiaoqiang who came to China is extremely confident, there is no discrimination here, no one knows his background, he is proficient in Chinese, there is no communication barrier, and he named himself Xiaoqiang is a symbol of his tenacious life.

That night, Duan Pingsi read a book and fell asleep in a hurry at one o'clock in the morning.

"Squeak!"

In the hazy eyes of sleep, Duan Pingsi seemed to hear Bai Mao's call, but it was not Bai Mao who climbed in through the window, but a man in black.

"Help!"

Duan Pingsi subconsciously shouted, he wanted to turn over and sneak away, but his body was like being glued to the bed, and he couldn't move no matter how hard he tried.

"Hahaha......"

Duan Pingsi seemed to hear the maniacal laughter of the man in black, and at this moment, "it" was already standing beside Duan Pingsi's bed, holding a sharp dagger in his hand.

"Look where you run this time, and see who will come to save you?"

As the man in black spoke, the veil on his face slipped down quietly, and Duan Pingsi could see his face clearly, it was a face similar to that of an ape, but there was a shadow of a human face in it.

"Zhang ......"

Duan Pingsi almost blurted out, because he seemed to see Zhang Yu's shadow on that ape-like face, and then thought that he was in danger at the moment, whether it was Zhang Yu or a stranger, he had no good intentions towards him, so he held back his words.

But at the same time, Duan Pingsi was crazy about his thoughts, how could the man in black in front of him be Zhang Yu, besides, Zhang Yu had saved his life in the Jade Dragon Snow Mountain.

At that moment, Duan Pingsi suddenly remembered Zhang Yuhang's words again, he said that Zhang Yu was an unpredictable person, and no one knew what he really thought in his heart, so that the person in front of him could indeed be a combination of Zhang Yu and the ape.

"Why did you kill me?" Duan Pingsi was already sweating profusely, but his mind was still quite clear, and he wanted to figure out why the man in black was chasing after him.

Time seemed to slow down a little, and the man in black didn't speak, but slowly raised the dagger, and then slowly stabbed Duan Pingsi in the left chest.

"Ahh

Duan Pingsi screamed, and at the same time, his body writhed strongly, just hoping to avoid this stab in the chest.

"Squeak!"

At that moment of despair, Bai Mao's cry was heard in his ears again, and Duan Pingsi felt that the small object he was holding tightly in his right hand was a gift from Bai Mao.

Due to the exertion of his hand, there was a "creaking" sound between the two discs of the small black object, and then the two discs spun rapidly.

"Bang!"

There was a sudden loud bang between the discs, and Duan Pingsi instantly lost consciousness.

"Bell!"

The dagger of the man in black stabbed in the air, and after hitting the metal bed board, it was bounced back, and the man in black stumbled and fell to the ground due to the excessive force.

When he got up again and tried to stab Duan Pingsi again, he suddenly found that the bed was empty, and the thorn just now only left a narrow crack in the quilt.

"What about people?"
