Xu Wanyin traveled through time and became Lin Ruhai's concubine.
Xu Wanyin, who thought Lin Ruhai was a little old man, decided to get the contract and run away.
She was bound to a system called many children and many blessings. Doesn't this mean that she was allowed to have children with an old man?
Xu Wanyin met Lin Ruhai for the first time. He was not a little old man, he was obviously a handsome uncle. Xu Wanyin immediately felt that the child born to such a handsome uncle would be very good-looking, and she would not suffer.
Intention: Many children, many blessings
