Reorganize Everything: Become Invincible from the Logic Restorer

The protagonist Su Mo works as an apprentice in a dilapidated repair shop that is about to close down, and awakens the ability of "logical repair". At first, he only repaired mobile phones and antiques, but soon he discovered that he could repair a person's "martial arts bottleneck", a chaebol's "luck break", and even a country's "technological lock-up."
