Life is such a mistake, life is so short, you never know what will happen to you in the next moment, it may be winning a lottery of 5 million, it may be being hit by a car while crossing the road and then being bounced back by another car, it may be seeing your wife hugging a bald fat man with a beer belly in a suit that you don't recognize and shouting sticky: "Honey, I have taken a fancy to a Gucci bag...", Or maybe being poisoned to death by your roommate.
All kinds of unexpected things happen so naturally. You can't deny that there seems to be a destiny trajectory somewhere, and people run according to this trajectory, just like a computer program has been written and the process follows the program.
Therefore, the occurrence of time travel, which is unbelievable to others, can often be regarded as a kind of destiny. When the right person encounters the wrong place at the wrong time, he should turn things around again and let him return to the right place at the right time to complete the originally designed trajectory. There are many ways to do this, such as reviving a dead body, reviving a dead body, exchanging souls, reincarnating memories...
Our story begins with time travel.
