Gamifying the World of Immortality, but Forgetting to Generate Players?

Everyone knows that there is a difference between immortals and mortals, and mortals without blood should become slaves of immortals, but Yang Xin doesn't think so. Is there any difference between immortals and mortals? No, no, you are all NPCs. People also say that immortals eliminate demons, and demons without intelligence deserve to be slaughtered by immortals, but Yang Xin doesn't think so. The immortal eliminates the demon? No, no, you are all NPCs. An immortal monster? That's the game monster refresh. Cave Heaven Blessed Land, Secret Treasure Land? That's a copy of the game. Immortal comes to seal and suppress monsters? That means the dungeon is not exited and the card monster is refreshed.
