I read this a while back and i don't remember what it was called. It was kinda your standard cultivation story where the MC was some secret super master trained in the mountains somewhere and he comes to the city to fulfill an agreement he had with his master to marry this girl. Everyone thinks the MC is a weakling because he never shows them his abilities. The MC is hunting for excaliburs to fuse into his sword or something. His wife was the young head of a struggling sect/family who took over after her father was killed. Some important story events were when he used his knowledge to save the son of the city lord from an illness, wiped out an entire rival family because they tried to kidnap and rape his wife's little sister, and later gets awarded a restaurant by the city lord which he uses to fleece a rich young master out of his money. Anybody remember what series this is?
