So is the cat.As Ren is pulled into something ancient and mysterious, he must decide if he's willing to take a different step in life or keep running from the world that hurt him.Because the city doesn't care if he lives or dies, but something in the dark might.(No system, no isekai, no reincarnation, no regression, no harem. The story focuses on mystery and character development.)

Soaking in lava, sleeping in an Ancient Killing Formation;

Traversing alternative worlds in a heavy armored vehicle;

Riding a Gundam Sentinel and slaying immortals with Godzilla...

I got myself a stat system, and from then on, I only beefed up my defense!

I just can't help it, I'm afraid of pain! The Daluo Golden Immortals of other worlds are all really fierce, and all of them know super ultimate move with infinite power. They have little meetings every day to discuss how to break through my defense.

I really don't know why they're so obsessed...XD
