Yu Wantang bound the regret system and passed through the endings that were doomed to regret.
As the medical girl Shen Qingtang, she once saved the sick and weak emperor who was sacrificed on a snowy night; she also used the name of Ah Tang to light the life lamp for the infamous master. The system said that the mission was completed and the regrets were reset to zero, but she gradually discovered that those people she had saved had traces of the same soul.
As long as the lamp is not extinguished, the old friend will not return.
The system wants her to make amends.
She wanted to change her life.
