Sam and the team left the realm the very next day.
Not before sending the maid to somewhere else. Sam removed the seal placed on her. The seal is quite perverted. Even though it seals off the energy, the body will not be affected. It would be as strong as the cultivator's body should be.
This is made in such a way because the other party wanted her to endure the violations. He wanted her to endure all the abuse and still recover so that he can continue.
He really felt pity for the woman.
After sending her off with the Dimensional drifter to the Naga Realm where his friend Yodha who just became an equal to his father, he came back and took his team to their next target.
As for why he sent them to the Naga realm, it is quite simple. The Naga realm has the miasma and the poisonous properties, even if the poison is not high level, it is very beneficial for the poison cultivators that want to build a solid foundation.
