Chinese monster taming novel

As it's been a long time i remember few things but i'll try to remember everything i can.

-Monster taming not sure if it's the power system or the main character's power.

-Seen as weak/trash bullying and so on

-Female sexy lady trainer inside a space inside him which he tries to assault only to be beaten up. She does not speak as far as i can remember so i'm unsure if she is alive. She uses a sword and trains him.

-Mother almost killed or kidnapped but she is saved by servants. One of the servants die .Main character speaks to servant when she is about to die.

-Goes to a dungeon or something similar. Tames a humanoid female monster which he almost kisses but is interrupted right before. Humanoid monster resisted his taming at first but when he gave up the taming attempt she allowed herself to be tamed. The monsters home was burning/destroyed iirc.

-Old expert soul awoke in his body and tried to take over him but was killed by female trainer immediately nothing big happened. Just mentioned in a paragraph.

-He and his mother is from some powerful clan but ran away iirc.
