Cheng He, an ordinary woman, once traveled through time and became the owner of a treasure without any effort. Once, she went out to adopt a child who was abandoned in the forest and grew up with animals. She called him Cheng Yu. Later, he was left alone by a dying man because of his effort, and he has been with Yaochi ever since. The three of them depended on each other until they grew up and Yaochi left. Wherever there is a cause, there must be an effect. From then on, we enter the world and live a long life.
Cheng He: The most important person in my life is Cheng Yu. Yu Tian please stay with him until he grows old and don't want him to be lonely
Cheng Yu: Sister, when we find Yaochi, we will go home, just like we did when we were children. OK.
Yaochi: Sorry
Yu Tian: Cheng Yu, from now on we are family. Let's wait for my sister to come home together.
