After Xu Mingrui dies unexpectedly, he transmigrates to another world and enters the Ancient Gods' Game. He thinks it's simply a game of life and death, never imagining that a powerful player would start manipulating him from his very first visit. As more and more people get involved, he looks at the endless karmic ties he has accumulated from across the Myriad Worlds and falls into deep thought.
Xu Mingrui: “Please leave me out of this, boss.”
The boss: “It's fine, it's just a little karma.”
Looking at the endless karmic ties he has accumulated from across the Myriad Worlds, Xu Mingrui can't hold back: “You call this a little karma?”
The boss: “Heh, I didn't expect so many people to follow me either.”
