Beginning: After I Bind the Host, He Will Be Completely Destroyed!

I am the system, yes, the golden finger in my imagination that can change people's lives against the will of heaven. But now I have encountered a very distressing problem... It is my host, after I told him what happened in the future and said that I could help him reach the peak of his life. This guy just put his * on and stopped playing. After taking down a bottle of sleeping pills, stretching his calves and closing his eyes, he was gone. So as a system, I am very troubled now. If the person is gone, what will I do? So I took his place and continued my life, but why did the plot get worse and worse? This novel and its characters are purely fictitious.
