Infinite Save Points in a Horror World

[Rewind + Wish-Fulfillment + Infinite Flow + No Female Lead + Not a Saint + Apocalypse + Supernatural Resurgence + Urban Fantasy] What should you do when a transformed old dorm supervisor and a black cat that came out of nowhere start fighting? Can't you two stop fighting already? Song Chi goes to great lengths to stop them from injuring each other for no good reason. It only takes him a few rewinds to succeed. His methods are just a little brutal. Looking at the dorm supervisor, whose head was blown apart by a gunshot, and the black cat pinned to the ground, he thinks to himself that it worked. “...” After great difficulty escaping the “Closed School” instance, he's approached by a System called the “Divine Selection Trial.” Countless more instances await him after that. Song Chi feels his vision go black. Just as he thinks his life is heading off the rails, he discovers he can enter the horrifying, hellish instances of the “Divine Selection Trial” ahead of time. With his ability to rewind, he's thriving, like a fish in water. A few months later, supernatural horrors descend across the globe. While everyone else struggles to survive in the terror of the supernatural resurgence, Song Chi has already swept away every threat, accompanied by all the horrors imprisoned inside his body!
