High Martial: From F-Rank Repairman to the Strongest

With an F-rank talent and no combat qualifications, Lu Heng can only pay off his student loans with nighttime maintenance jobs.

But nobody knows that [Myriad Calibration] lets him see imbalances in the structure of all things.

Broken equipment? Fix it.

Flaws in a martial technique? Fix them.

The city's defenses collapsing? Fix them.

A mutated beast's armor too thick? Find its weak point and smash it to pieces.

Starting with a single streetlamp, Lu Heng works his way up to the top of his school, the top of a hundred schools, and the top of humanity.

Until the civilization System keeps answering, "Normal," while cities begin falling one after another.

Lu Heng looks up at the world spiraling out of control.

"Don't panic. It can still be fixed."
