Shen Jiayi is an avid horror game fan despite him being unable to stand them. It is his guilty pleasure. In order to help him go through the horror games, he usually does live streams. Over the years, he had garnered quite a lot of loyal fans. One day, one of his top fans and fan club manager suggested that he do a video blog on one of the abandoned hotel with some fans as a way to get to know each other. And this is the start where everything goes wrong.

The video blog recording should've only taken five days at most. One day, Shen Jiayi woke up in a different place, and his memories of the past few days were blank. As he opened the door to the hallway, he noticed the eerie atmosphere almost immediately. Walking few steps, he then realized the door from before had disappeared.

As he continued to explore, he suddenly sensed a hint of danger behind him. When he turned back, he saw a tall figure covered in dark mists. Based from the height alone, Shen Jiayi knew that it was not human. At the foot of the figure, lay a bloodied mess of a corpse which then further triggered Shen Jiayi's warning bell.

He ran to escape, but as he entered a room, he suddenly found himself to have entered the NightMire and a system was bound to him. According to the system, he was already dead, and how he died? He himself didn't know. To find out, he had to participate in game worlds where his survival rate will be graded and points will be awarded. Depending on how many points he gain, he will be sent back to his world moments before his death.

Faced with a choice of eternal death or a chance to survive, Shen Jiayi decided to try his chance. But he soon regret his choices as he ended up experiencing death after death with each world he visited.
