The rain is pouring down.

A novel about cultivation that combines the power struggles of the sect, disputes in the fairy world, and counterattacks and growth. 
The abandoned son of the sect, Gu An, was forced to marry into the family, but he used the wedding to expose the inheritance of the God. 
He broke through step by step, and transformed from a puppet in the marriage to a behind-the-scenes God who subverted the fairy world.

Yeah, I am Gu An, from the story above.
Transmigrating into a world of cultivation, I find myself at the lowest rung of the sect's hierarchy. Everyone wants to bully me to gain some benefits. Fortunately, there are always a few junior brothers and sisters who are 'generous and understanding', allowing me to improve peacefully and secretly grow stronger. Years later, unbeknownst to anyone, I successfully become a deity within the sect. This day, my master visits me at the sect's request.
'The upper echelons of the sect believe you have been diligent and loyal over the years, and though your strength is mediocre, you are an honest person, so they've found a marriage alliance for you.'
'An alliance marriage?'
'Not exactly. The other family has a rule: marrying into their family means taking their surname.'
Is this... becoming a son-in-law who marries into the wife's family?
Looking at the long sword before my neck, it was obvious that they didn't give me too many substantial opportunities to choose.
What should I do?
