[Construction work + live-in son-in-law + tycoon + antique appraisal + divine restoration skills]
To pay for his critically ill daughter’s surgery, Lin Mo, a graduate of a prestigious university, gave up his dignity and became the Su family’s “useless son-in-law.” He hauls bricks at a construction site by day and goes home to do the laundry and cook at night, enduring contempt and humiliation.
When his brother-in-law hits someone while street racing, his mother-in-law forces Lin Mo to take the blame and go to prison, while his wife looks on coldly. At the point of despair, Lin Mo makes an astonishing discovery: the heirloom Luban Lock he picked up while at university is actually a divine artifact containing the legacy of an ancient master craftsman!
He unlocks the Luban Lock, and divine power floods into him!
He gains the [Divine Craftsman’s Hand], which can repair anything in the world, from antiques and paintings to the body’s meridians. Nothing is beyond its power!
