Go to become a god, let me marry into the sect

Traveling through the world of immortal cultivation, you become the outermost bottom of the sect. Everyone wants to bully someone and gain some benefits, but fortunately there are always some junior brothers and sisters who are "generous" and "considerate", so that we can make steady progress and become stronger secretly. Many years later. Without anyone noticing, you successfully became a deity in the sect. On this day, the sect sent your master here. "The sect's leaders think that you have been in the sect for many years, have been law-abiding and loyal, and although your strength is average, you are an honest man, so they found a marriage for you." "A marriage of alliance?" "Not really. The other family has a rule that if you marry them, you have to take their surname." Is this... being a son-in-law?
