Parallel worlds, which can also be called parallel universes.

In the 5th century B.C., Democritus proposed the concept of "infinite worlds", arguing that "countless worlds" were formed by atoms moving themselves.

In the first century B.C., Lucretius pointed out that beyond our "visible world" there were "other worlds" inhabited by "other races of men and beasts." ”

In the 4th century B.C., Epicurus expressed the idea of the plurality of the world: "There are infinitely many worlds, some of which resemble our world, and some of which are not. In all worlds, there are animals, plants, and other things that we see in this world. ”

In the 17th century, Leibniz developed his concept of "possible worlds", which envisaged the existence of an infinite number of "possible worlds" beyond the confines of the necessary world (the observable universe).

In the 50s of the 20th century, some physicists found that the quantum state was different each time when observing quanta, and scientists speculated that since each quantum has a different state, then the universe may not be one, but composed of multiple similar universes.

At this point, the concept of parallel universes was officially proposed, and with the development of modern quantum science, it has become more and more recognized.

"I think the ghost is entering another world parallel to our space." Mu Yuan said, "This is also very understandable, people who have just died, or some powerful ghosts, they are contaminated with the breath of our world, or the energy is too heavy, and they can't break through the barrier, so only after transcendence or baptism, can they resolve the so-called resentment, and then they can break through the barrier and enter another world." And these parallel worlds can be transformed into energy, which can also explain the theory of reincarnation from another angle! ”

"You mean there really is heaven and earth?" Yin Hao asked.

"Who knows?" Makihara shrugged, "It's just my own speculation, and I've never discussed it with anyone, I asked the teacher when I was a child, but I suffered a lot!" ”

Hearing Mu Yuan's words, Yang Song smiled, he knew these things. When he first entered elementary school, Makihara was often punished for standing because he liked to listen to the village elders tell him strange things, and then ask the teacher for advice. As a result, Makihara was classified by the teacher into the ranks of bad boys. Thinking about it now, Yang Song is actually quite sad, many people like to stand on a high position in morality or science, suppress those dissenting opinions, and do not want to hear the slightest paradox. Perhaps, this is the so-called scientific authority that Makihara hated so much, and these authorities were in the hands of a few, and gradually became a tool of ideological domination.

If you think about it, from childhood to adulthood, there are so many things in this area that have been written into the textbook and instilled in every student one by one.

"If the theory of countless worlds is true, then this countless world must also be made up of countless miniature parallel worlds!" "For example, the universe is composed of countless Milky Milky Ways, the Milky Way is composed of countless solar systems, and the nine planets in the solar system have their own satellite systems, which shows that the forces between parallel worlds are large and small, and they are a system of their own and have their own operating laws." Imagine that if the yang and the underworld are in the same system, then there must be energy conversion between the two parallel worlds, just as the earth and the moon attract the moon, and the moon can cause tidal action. Moreover, parallel worlds are not parallel lines, the two can overlap together, but there are differences in latitude in space, time, etc., if so......"

As he said this, Makihara suddenly stopped, his eyes glazed over, as if he was caught in the world of self-thinking.

"No wonder many people say that the many-world explanation is undoubtedly the boldest and most ambitious theory ever proposed." Yin Hao said, "After listening to your guy's thoughts, I don't think this statement is an exaggeration at all!" ”

Mu Yuan smiled and said, "That's why I asked you to help me, if you want to better understand this world, you must rush to the front line!" I have only one belief that all weird phenomena have a truth, a learned and reasonable explanation, and the best solution hidden! ”

"Muyuan, I think it's better to forget it!" Yang Song persuaded.

Mu Yuan knew Yang Song's thoughts, he smiled gratefully at Yang Song, and said, "Brother Song, thank you, but I have my own problems to solve, but, I can guarantee that I will be careful!" Trust me, I'm not a reckless person! ”

Yang Song wanted to persuade two more words, but the words came to his lips and he took them back. Mu Yuan is indeed not a reckless person, although he does not know the reason for his stubbornness, but Yang Song believes that Mu Yuan must have his own difficulties, and all he can do is understand and help.

"Makihara, do you mean we're going to continue in the future?" Yin Hao couldn't hold back the ecstasy in his heart and asked.

"Hmm!" "But we also have to restrain ourselves and try to minimize the impact, you don't want to be locked up in a mental hospital in the future!" ”

"No problem!" Yin Hao agreed, and he had an idea, as long as he could continue to follow Mu Yuan's ass in the future, "I will carefully sift through the information and eliminate all troubles!" ”

Mu Yuan nodded, he believed that Yin Hao could do this, just kidding, he couldn't even do this kind of information identification, what kind of top hacker was he.

"Makihara, can I ask you a question?" Yin Hao suddenly spoke.

"What's the problem?"

"Can you fly?" Yin Hao asked.

"Fly?" Mu Yuan knew that Yin Hao liked the non-movie of "The Matrix", but he didn't expect him to really think of himself as the leading actor, so he said angrily, "What is it to fly, buddy, I can cross!" ”

"Really?" Yang Song was also surprised, although he didn't believe it, he couldn't help but ask.

"Brother Song, have you also watched too many fantasy novels and science fiction movies?" Makihara said with a smile.

"Cut!" Yin Hao couldn't help but stretch out a middle finger, his face full of disappointment.

When it comes to time-traveling novels and time-traveling dramas, Mark Twain's "Connecticut Yankees in Arthur's Dynasty" is generally considered the world's first time-traveling novel, but as early as the Tang Dynasty in China, this kind of bloody plot has been abound in various love legends. And the contemporary Li Bihua's "Qin Warriors" (directed by Cheng Xiaodong, starring Zhang Yimou and Gong Li, the movie "Ancient and Modern War Qin Warriors"), Taiwan's Xi Juan's debut "Love in Staggered Times", and Huang Yi's "Looking for Qin" set off the climax of the time-traveling novel, but what Muyuan didn't know was that in a few years, all kinds of time-traveling novels began to be popular on the Internet, and the way of crossing was even more brain-opening, the plot of a group of wives and concubines is very satisfying to the reader's fantasy.

"It's not early, I'm going to class after breakfast!" Mu Yuan looked at the table below, it was already seven o'clock in the morning, he reached out and took the packaging bag given by Cui Laibao yesterday, and said with a smile: "Let's start to divide the spoils!" ”

"Spoils? Makihara's money is yours! ”

At the beginning of 2000, the per capita salary of the city was not high, and the salary of college students who had just graduated was less than 2,000 yuan a month, and 20,000 yuan was almost a year's salary. Although Yin Hao looked at this money with greed, he also knew that this money only belonged to Mu Yuan.

"The seeer has a share, you have been running around for the past two days, why do you have to earn an errand money!" Mu Yuan said, and threw 10,000 yuan on the coffee table, this action, even Mu Yuan himself found a little bit of the feeling of the master, "You have divided these!" ”

"That's too much, isn't it?" Yin Hao and Yang Song, you look at me, I look at you, they are all a little surprised.

10,000 yuan, if the two of them divide it equally, it is 5,000 yuan per person, which is almost the living expenses of an ordinary student for ten months, which is enough for a semester of expenses if they are a little extravagant.

"Makihara, this ...... That's a little too much! Yin Hao waved his hand, he felt that the money was a bit prickly, and he didn't do anything from beginning to end, except for answering a few phone calls and being a return microphone, the rest was to follow Mu Yuan's ass as an audience.

"That's right, Makihara!" Yang Song also said, "I didn't do anything, I can't take this money!" ”

After some excuses, Yang Song took a thousand, his family is good, and a principal's uncle often stuffs him with pocket money, he doesn't have to worry about living expenses at all, and the reason why he wants that is also for Yin Hao's sake. Yin Hao also wanted to take a thousand, but in the end, Mu Yuan directly gave him 5,000, 2,000 is an errand fee, and the remaining 3,000 is used to upgrade the website, buy a server or something, which is considered a hardware investment. Actually, Mu Yuan is still very grateful to Yin Hao, this time because of Yin Hao's curiosity, he picked up a spirit coffin for nothing, that thing is a murder weapon in Cui Jinyuan's hands, but in Mu Yuan's hands, it is a big magic weapon, a treasure that money can't buy.

"Am I on a thief ship?" Yang Song took the thousand yuan and said stupidly, he was originally going to persuade Mu Yuan to give up, but he didn't think that he was pulled into the fire.

"Alright, let's eat the whole thing!" Makihara said.

Several people did not go downstairs, but cooked several bags of instant noodles together. While cooking, Mu Yuan was still thinking about whether he would go directly to the antique market today and buy some five emperor money, he didn't have much heart to go to class now, the six-pointed star array had been wandering around in his head, and he was unwilling to do so if he didn't put one out by himself for a day.

It's just that Mu Yuan didn't expect that his entire plan was destined to be disrupted today, because it was just last night. There was another big case in the city.
