Virtual Time Travel

It's a good book with a good theme and a good beginning, but what the hell is the Resident Evil chapter? It seems that the protagonist is leading step by step, but in fact he is lagging behind every step, and the villain can easily overtake him! Selectively forget the killer weapon you possess. The protagonist drags the plot and is speechless...

Oh mom. . . Author, I read this novel of yours when I was a child. . .

This book is very interesting for those who are interested in technological science fiction novels. The protagonist in the book goes to various science fiction worlds (movies, large-scale science fiction games) to plunder and collect unique technologies to develop himself.
