Murong Lingran, who was originally an ancient person, accidentally traveled to the 21st century and lived for 20 years. She was killed when she was bumped and killed while trying to save her child on the way to moving house.

She returned to the ancient times and saw her original family again. Before she could rejoice, she found that she was being swept out of the house, and their family was injured and scattered, and they didn’t even have a place to live.

She clenched her fists, it doesn’t matter, there is space behind her and the omnipotent gods and beasts help, no matter how big the difficulties are. There will be money, houses, fields, manors, shops, and family reunions. It’s just that she didn’t expect that she would accidentally hug the thickest thigh, the kind that doesn’t want to be hugged.
