On the day when the fire in the ancestral hall burned away the loyal soul, young Ye Chenyuan clutched the blood-stained short blade and vowed revenge. Five years later, he shocked the Red Maple Pavilion's "Maple Shadow Terrace" with one move, and was willing to transform into a blade in exchange for Nangong Fengyan's help. When the jade flute and the short blade collide, the life-and-death covenant between their fathers is involved. The conspiracy secrets in the dark room and the cries for medicine in front of the Jinluan Palace push the three of them into the maelstrom of intrigue.
The third prince Li Jinheng did not hesitate to kneel through the imperial steps to save his old friend; Ye Chenyuan faced the unconscious Nangong Fengyan, hiding his throbbing in the mist of medicine. The medicinal soup boiled with ambergris is steaming with secrets. When the nine-turn life-sustaining pill rolls down, the temperature of the lips and teeth touching is the benevolence of the doctor or the beginning of love?
Gratitude is like a knife, and fate is like a chess piece. They redeem each other in the bloody conspiracy, but they don't know that they have already fallen into a game within a game that started from their parents and was trapped in their own hearts.
