There Are Demons Everywhere, I Rely on Simulation to Fight Them All

[World of Monsters] [Invincible] [Simulation] [Save the Human Race] [Arbitrary Eternity] [War between Humans and Monsters] Xu Xuan, who was reborn due to a car accident, was accidentally born into a world ruled by demons. For his own survival, and for the survival of all mankind, he had no choice but to start simulations again and again to win a chance for himself. When he defeated all the enemies and looked back, he was already standing on the top of the mountain. [In the first month, you fully understood that you were reborn as an unborn baby. In desperation, you had no choice but to accept this situation and began to wait silently for birth. [In the fourth month, you feel that your body is growing bigger and stronger, and you start to move restlessly and frequently. [On the day of the fifth month, with a loud baby cry, you were born. As a born time traveler, you were unusual when you were born. You didn't cry loudly like an ordinary child. Instead, you stared at the whole world with wide eyes. This was your first time traveling to a different world, and everything seemed so fresh. [Soon, through your observation, you find that you are in a stone house with four bare walls. There is only a stone bed in the entire stone house and nothing else. In addition, you are surprised to find that the situation of human beings in this world seems to be worse than you imagined. Your parents are all destitute, and there does not seem to be a unified language and they just howl to communicate like primitive people. This situation makes you very distressed. After all, through the system prompts, you can imagine that humans in this world are miserable, but you never expected that they could be so miserable.
