Was there a plot in a fantasy novel where the protagonist came from a powerful family and created his own faction?

Yes, I recommend [Spirit Silence]. The main character, Ling Yang Teng Yu, was a young master of a noble family with a prominent background. He established his own force and took in a divine beast as his mount. He would kill anyone who stood in his way. With the Nine Heavens Black Zither in hand, what was there to fear? I hope you like this fairy's recommendation. Muah ~😗
