Reborn in the Cultivation World, I'm Forced to Live Off Others

{This isn't a dumb, simplistic novel. There is no System, and the protagonist is intelligent.}

Xiao Rong, a highly educated man from the twenty-first century, seems to have transmigrated. His new body belonged to a genius. When Xiao Rong transmigrated, he was in the middle of receiving a supreme legacy. After obtaining it, he faced some hardships at first in this world, but eventually rose to great power. Before long, the time he had promised to meet his childhood sweetheart arrived, and Xiao Rong returned. After all, it had been his body's original owner's mother's dying wish. It was only a live-in son-in-law position. Did they really think a man from the twenty-first century would be like the ancients? Still, he should explain everything to his childhood sweetheart. If it didn't work out, he could just call off the engagement.

Live off a woman? I'm so strong, why would I need to?

Later, Xiao Rong lies in bed, enjoying his childhood sweetheart feeding him.

“Delicious!”
