Ring the Doorbell in the Middle of the Night

Chen Yuan was originally an ordinary college student who was running to save his terminally ill sister's life. However, late at night when his sister was undergoing surgery, he was dragged into a game called "Death Game" by an invitation with the smell of death. Here, he can survive by copying other people's professional abilities, and he can also obtain "life-extending chips" to save his sister by clearing levels. But the opponents in the game all have ulterior motives, and there are countless traps hidden in the fog of each game. Every choice may be a fork in the road between life and death—— He wanted to survive in this life-for-life gamble, and he also wanted to have the hope of living for his sister.
