Seven Nights Cycle

An ancient city that reincarnates every seven days. There are "seven major families" living in the city, and each family has a "token". Ordinary people are selected to enter the city and must pass the "blood test" to survive. Pass seven tests in seven days. Each test is a psychological game + reasoning. If you win, you will get "bloodline points". Those who don't have enough points will be wiped out. Chen Mo is an ordinary person, indifferent on the surface, but actually proficient in psychology and game theory. The purpose is to find out the truth about reincarnation and escape from the city.
