Ji Xuanyuan received an invitation letter called "Real Scene Experience Officer". The activity was similar to a drama-type immersive script killing. The high reward made him excited, so he went to the appointment according to the address. There were also 8 people participating in the event. They were of different ages, different jobs, and both men and women. On the night of the event, everyone discovered a body and were told that they needed to find the murderer, otherwise one of them would die every day. If the murderer is found, the survivors will share 1 billion in cash, and the last person alive will get 2 billion in cash.
