The game of doomsday life and death

Su Chen, an ordinary 16-year-old boy. Poor physique and poor study. In a game, I accidentally crossed into a different world. There are striking similarities between the world and the overall setting of the game this is a game, a game of life and death. There is only one end for people without strength, that is death everyone who participates in this game has only two choices: die or become stronger!
