Humanity's First Warrior

“My parents died protecting me.”
“I only wanted a better, average life with my younger brother, but life knew how to punch you in the face. Nothing ever goes like I wanted.”
“I started with the thrashest F-level trait possible, but so what? I’ll never surrender or resign myself to fate.”
— Ash.
Two hundred years ago, humanity opened portals to other dimensions, but involuntarily, they ended up bringing their worst nightmares to Earth—otherworld monsters that killed everything in their path.
Mana came with the beasts, strengthening humanity’s bodies and allowing them to awaken traits to fight against the beasts.
Yet they were still too weak. The only option found for surviving was to enter other worlds, steal their resources, and empower themselves to fight against their enemies.

This novel is inspired by one of my favorite Korean novels, which I had the pleasure of reading. However, the setting is entirely different. If you have read it, you\'ll likely recognize it in the prologue.
