Did the main character enter Bio-Experimental by himself and then enter Infinite Terror after completing the mission?

I recommend 'My Life in the Otherworld' to you. The protagonist of this novel, Xu Yi, was brought into various horror worlds by a mysterious force to complete a mission, including the biochemical world. After completing the mission, he entered a world of infinite horror and experienced an even more exciting survival game. I hope you like this fairy's recommendation. Muah ~😗
