The world is described as huge. The upper and lower parts of the hourglass represent the human world and the demon world respectively. The middle is the gap in time. The hourglass symbolizes the flow of time and destiny. Under normal conditions, time passes in one direction and all life is orderly. However, due to the continuous war for thousands of years, the balance of the hourglass has been broken. A periodic rewind begins, reset every 60 years. Old things are immortal and memories remain (time rewind is not a complete re-enactment, the details will change due to choices, forming time branches). The enemy leader must be killed within 60 years, otherwise time will be reset and everything will return to the starting point. The demon leader is the core of reincarnation, but he is also an eternal existence and can only be assimilated by blood and die. The cycle can only be broken when he dies in reincarnation. The main CP is two women, the deputy CP is two men
