The villain, the Son, frantically attacked them in order to survive

(Harem! All accepted!)
Lu Mu traveled through time.
Traveling to his first novel, he became the villain he created with his own name.
He was beaten violently by the protagonist in the early stage, and was killed by one of the important female characters. Without anesthesia, he ended up with no bones left.
In order to survive, he decided to start with the women that the protagonist will acquire in the future!
Ask the genius daughter of an ancient family, the future empress of the Supreme Ancient Kingdom, the domineering empress of the Wanli Demon Realm, and the ice-cold sword fairy of the great faction of the general world, all of them have to establish a good relationship!
Just when Lu Mu was winning all the way, he realized...
Why is the protagonist also a woman?
