One Hammer Blow Killed a Demon God. This Is a Mecha Mechanic?

He transmigrates and is reborn in a world of mecha and monsters.

He has a sister and a house, his parents are both dead, and he inherits the family mecha repair shop.

He thought life would be twice as good, but unfortunately he failed to awaken a psionic talent during the college entrance exams, and the family savings were running dry.

Luckily, at the crucial moment, he awakened the God-Tier Mecha System.

No matter how badly damaged a mecha is, it can be perfectly repaired, and even given additional upgrades.

After each repair, Li Mengsheng also receives rewards to strengthen himself!

[Extendable Dark Gold Battle Blade repaired successfully. Psionic transmission rate +10%, sharpness +200%, durability +100%.]

(Reward: Universal Mecha Core)

[Level-One Mecha Module repair complete. Mecha speed +20%.]

(Reward: God-Tier Psionic Talent, Telepathy)

[Level-Nine Starbreaker Mecha repair complete. Energy-Concentrating Arc Launcher unlocked as a bonus.]

(Reward: Godslayer Mecha Module)

With every repair and reforging, Li Mengsheng goes from a useless man with no awakened psionic talent to a mecha master of godlike rank!

Just then, Void Demons lead countless monsters and join forces with human traitors to destroy humanity once and for all.

Li Mengsheng stands alone in the sky, with god-tier mecha masters at his back.

In the blink of an eye, the Void Demons are wiped out!

The demon lords in the void tremble in fear: "These are all god-tier mecha, and you call this a low-level civilization?"

Also known as: You asked him to repair mecha, so why did he replace and upgrade them instead?
