During the Liang Dynasty, the border was in a hurry. Everyone knows that General Xiao Lie is a Shura in troubled times, but they don't know that there is a mute girl named "Ah Qi" hidden in his house. Xiao Lie was decisive in killing others, but extremely gentle at home. He often washed his hands and cooked soup for Ah Qi after returning from the bloody battlefield.
However, Ah Qi is not an ordinary person. She is the "Experimental Subject Zero" secretly cultivated by the enemy country. She has immortality and terrifying destructive power. However, due to the side effects of the experiment, her memory is confused, and she sometimes becomes crazy and sometimes sluggish. Xiao Lie knew everything. He used her power to put down the rebellion, and in the dead of night, he tried to tame this murderous weapon with warmth.
When Ah Qi's memory gradually revived and she realized that she was just the knife in Xiao Lie's hand, and a stepping stone in his machinations, the madness in her body completely exploded. That night, the General's Mansion was filled with blood. Xiao Lie, holding the cold soup, looked at Ah Qi who was covered in blood but smiling sadly, and finally understood: he had tamed the beast, but lost his lover. This is the ultimate sadomasochism that begins with calculation and ends with heartbreak.
