Seven years ago, the Gu family collapsed overnight and everyone was convicted.
The young man Gu Zhao died on the road to exile, with no bones left.
Seven years later, Xie Huaichuan, the powerful Marquis of Dingyuan, returned to the capital in the snow. No one knew that he was Gu Zhao who was lucky enough to survive back then.
He changed his name, took military power, and set up a trap step by step, just to make everyone involved in the old case pay with blood.
Lu Mingyi, the legitimate daughter of the Minister of Rites, is noble, self-possessed, smart and proud, and is also the most beloved daughter of his enemy.
He approached her to investigate the case. Using her is for revenge.
Destroying her family was the vow he made seven years ago.
But when Lu Mingyi personally uncovered the numerous old crimes in her family's name, when she would rather give up her glory and seek justice for the innocent, Xie Huaichuan was shaken for the first time.
Later, she stood between the Lu family and him and asked him:
"If my father is guilty, you will kill my whole family; then how are you different from them back then when you hurt innocent people today?"
Xie Huaichuan had been planning for seven years and never made a wrong move.
But he didn't expect that he would fall in love with his enemy's daughter.
He came to Chang'an to collect debts, but she became the pawn he was most reluctant to leave behind in his life.
Old sins will not be forgiven, nor will deep feelings be forgiven.
