My Senior Sister Taught Me Dual Cultivation, but It Keeps Getting Weirder

This novel has a lot of erotic descriptions and is quite detailed. But the plot felt a bit hard to understand. I watched part of it. First of all, the secret altar was sucked in by something, and the yin and yang must be balanced, so he was a dual practitioner with three women, but only men or women wanted to go in. Wouldn't that mean death? Also, before entering, one of the women's clothes was burned off and was looked at by the sect leader. The author said it didn't matter. Then, those who dared to attack the sect and kill the sect leader were beaten away and killed by him. Then the subsequent description made the protagonist feel weak and pitiful. The golden rooster was directly beaten away by the senior sister. This can also be said to be embarrassing for the protagonist. But a scorpion shot later failed to break the defense, and then the senior sister left the unit and ignored orders to protect the protagonist. I feel that the author is not suitable for writing novels, and is more suitable to write details on the moderator. 🤦 Well, by the way, another point is that the portrayal of the protagonist feels like a lustful and shameless person. I don't know why I liked him as soon as I saw him?

Is this written by a normal person?
