Gunslingers Are Weak? My Firepower Is Overwhelming

[Universal awakening + System + mechanical upgrades]

Xiao Chen transmigrates into a world where everyone can change class, becoming a gunner. But because technology-based classes consume so many resources, everyone looks down on him.

Fortunately, he awakens a sign-in System and gains a growth-type S-rank talent: Saturation Boost!

You say I can't afford bullets? I'll make my own!

You say gunners are weak? Just watch me lay down a barrage of fire!

Level 1 talent: Multiply the number of technological creations by 10 and the number of attacks by 10.

Level 2 talent: Multiply the number of technological creations by 100 and the number of attacks by 100...

The talent gains one level for every ten levels the user gains.

Years later, when the myriad races set out to destroy humanity and humankind teeters on the brink of extinction, Xiao Chen sits atop a mechanical throne and arrives through the void aboard his immortal City of Machines.

With a wave of his left hand, countless cannons unleash billions of attacks.

With a sweep of his right, countless mechanical minions destroy all things.

“You want to destroy the path of machinery? Did you ask me first?!”
