Obtain Invisibility at the Beginning of the Game of Life and Death

Zhao Ziyun was originally a modern ordinary white-collar worker, but because of a car accident, he was transported to a three-year-old child in another world. When he first traveled through time, he thought this world was an ordinary world. However, when he was seven years old, he suddenly heard a voice. "The game of life and death has officially started." Zhao Ziyun originally thought that only he heard it, but when he saw the reactions of the people around him, he understood that the whole world had heard this sound. Sir, please clarify that no matter how old you are, you will enter the game of life and death, but the level is different and the difficulty is different. The level of 1-6 years old is relatively small, and they basically survive in the ordinary urban world for ten minutes or an hour. The level of 7-18 is a bit higher, and they are doing tasks in the low-level anime world. Detective reasoning and so on, and tasks like 19-100 and above are particularly difficult. It is possible in any world of immortality, and you may encounter very simple ones. Then if you are over 50 years old, you have a 50% chance of encountering very simple ones. The older you are, the greater the chance of encountering simple ones. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
