As a general of the Fifth Army of the Empire, Su Yuzhi was ruthless and decisive in killing. Although she was the adopted daughter of a merchant, her mother who died in the merchant's laboratory was a blood stain in her heart that she and the merchant could never get over.
When the fake daughter named "Shang Nianhe" returned to the business in disguise, Su Yuzhi saw through her trick at a glance. She didn't reveal it because she wanted to know whether the arrival of this girl would reveal the truth about her mother's death.
Xue Chengxu, an orphan from the slums, took on the skin of a noble lady in order to repay his kindness. She is a dark sentinel, and her spiritual body is the deadly Black Mamba, but she tasted the heartbeat for the first time in the ice and snow world of her "sister" Su Yuzhi.
Merchants sell psychotropic drugs called "Tranquility", but they are actually conducting transformation experiments that eliminate human nature. The real Shang Nianhe has already transformed into the leader of the "Dark Crow" in despair, vowing to drag this decadent empire into hell.
In this game between the empire and the rebels, two women who were supposed to be mortal enemies heard the resonance of each other's souls in the depths of their spiritual connection.
"Su Yuzhi, if I was also a part of this evil, would you still hug me?"
"Your soul is clean, that's enough."
Intention: I will always stand by your side
