The System Gives Me Great Strength: I Get Furious Opening Mystery Boxes!

He transmigrates to a parallel world and ends up as a shut-in.

A System is practically a must-have for anyone who transmigrates.

So where's the promised soft, adorable girl voice for the System?

Why does it sound like a sleazy old man instead?

And it's not just the voice that's sleazy. The missions are sleazy too, and the System has an insanely obnoxious knack for tempting him to court death!

What? You want me to beat him up? Come on, I have no grudge against the guy!

I'll get stronger by beating him up? The angrier he gets, the stronger I become?

Could I become the first powerhouse in history to literally anger someone to death?

That's way too despicable!
