The CEO's loser wife: Rebirth of the villainous queen of alchemy - Chapter 178 Massacre in the ghost lands Part 6

One week. If you survive, you choose a Cosmic Power... you survive. Jace isn’t one to give up. Not when his sister dies. Not when he loses his legs. And definitely not when The Cosmic System takes over Earth. With nothing more than his street smarts, the clothes on his back, and a river otter companion; he must survive a planet full of vicious predators that see him as an easy meal. If he can survive? He gets to choose a Cosmic Power and a Class. A path to ascension. A way to bring his sister back.

Possessing immortal arts, he can give life and he can bring death. Treading upon thousands of heroes, every corner of the city has his legend…

I became the childhood friend of the protagonist in a novel. The childhood friend who died from taking drugs.
