Jiang Zhuifeng, the heir of Mount Qingcheng, goes down the mountain carrying three letters of engagement. His first stop is the Su family engagement banquet, where he kicks a bank card to pieces, breaks off the engagement on the spot, and slaps faces. Turning around, he encounters Wen Zhiwei in a wheelchair, instantly seeing that she is not disabled, but poisoned. With silver needles in hand, he forces out the truth, and also forces out the dark hands of the Wen family's second uncle and the Huo family. He protects her as she stands up, accompanies her to investigate her father's cause of death, and fights from the banquet hall to the underground pharmacy, until the sect traitor finally shows his true form. Cleansing the sect, settling the winds and clouds, and exhausting the letters of engagement, in the end, he only chooses the one who dared to block fire for him.
