Her Shen family who sacrificed themselves for the country and the Emperor, not a single one of them were lucky enough to escape. With the change of one dynasty, everything was overturned. Her clan perished and she had to mourn for her children.

Shen Miao never thought that being a married couple who have gone through trials and tribulations and mutually assisted each other was just a stage joke to him!

He said, “Seeing that you have followed Zhen for twenty years, Zhen will grant you an intact corpse. You should thank this kindness.”

Under the three Chi (1 chi = 1/3 meter) of white silk, Shen Miao made a malicious vow: In the time to come, she will take part in each and everyone’s end!

Upon rebirth, she returned to the time when she was fourteen, when the tragedy had yet to occur, her family was still alive and she was still the pure, amiable, quiet and yielding Di daughter of a military lineage.
