DoubleHush

Meet Alex Knight, a hardworking young man burdened by crushing debt and a bleak future. When his new boss turns his life into a waking nightmare, Alex finds himself trapped in a job he can't escape, his future held hostage by the whims of a tyrant. 
Just when he believes he has one anchor left—his girlfriend's love—a devastating betrayal leaves him utterly broken. 
But then the world changes. The system descends, dragging everyone into a chaotic new reality. Alex becomes the first to sync with it, earning a mysterious title: 
[Apocalypse Baby]
[You have awakened the skill: Exploding Touch]  
[Anything you touch turns into a bomb.]
Armed with a deadly gift, Alex rises from the ashes of his former life to become an unstoppable force in an urban fantasy world where power rules and vengeance drives him forward.

Apocalypse Baby

A chime echoed in Alex's mind, accompanied by a glowing notification.

[Would you like to use Upgrade Stone on a skill?]

"Yes!" Alex growled, his grip tightening around the upgrade stone as he sprinted.

"Exploding Touch," he muttered, narrowly dodging a black flame blast from the elder shaman.

The fiery attack slammed into a tree, reducing it to ash in seconds.

The intensity of the monkey's onslaught had reached a dangerous peak, and Alex could feel the heat radiating against his skin.

[Would you like to use Upgrade Stone on Exploding Touch?]

"YES!" Alex shouted, his voice raw with frustration.

He leaped to the side as a flame dragon soared past him, the searing heat brushing dangerously close.

The attack smashed into a nearby tree, devouring it in a swirling inferno.
