You Made a Nuclear Bomb by Hand, and You Call Yourself the Weakest Gunsmith?

System, universal class advancement, invincible, hilarious, absurd: a game descends upon the world.

The game descends upon the world, and countless realms overlap! Not only are monsters running rampant everywhere, but the wilderness is also full of dungeons and secret realms.

From then on, Blue Star enters the age of universal class advancement.

On the day he changes class, Zhao Lin becomes a firearms master with an eccentric style.

God-Tier Modification Talent: He can freely assemble the properties of any weapon he owns, alter its appearance, and upgrade the quality of the assembled weapon.

Have you ever seen a Barrett sniper rifle with a Gatling gun's rate of fire?

Or a submachine gun whose bullets pack the power of a nuclear bomb...

Two-Dimensional Foil: It can launch a dimensional strike on a specified area, collapsing three-dimensional space down into two dimensions.

Have you ever seen an artillery master wielding dimensional weapons?

Looking at one world-destroying skill after another, Zhao Lin was utterly baffled.

"These skills are just a little too ridiculous!"

Until one day, the myriad races invaded.

Facing reporters from around the world, Zhao Lin stood on a little fishing boat and unleashed the ultimate Reaper Ray.
