In the interstellar era, when human beings gained "immortality", World (SJ) Company developed a death experience game. Let people experience death in different eras, different identities, and different genders, and even participate in or promote the death of others...
In order to pursue excitement, more and more people are participating in this game, and the role players in the game may be set NPCs, or they may be your friends.
[Death is not a matter of one person. You may have participated in this 'obliteration' without realizing it. You are a participant in the game and a viewer of the game]
Purpose: To realize the fragility and shortness of life
