Si Luo, the national master of Tianji Pavilion, is the incarnation of the way of heaven in the eyes of the world. He had calculated all the secrets, but he could not figure out his own emotional calamity. In order to overcome the calamity, he found a strange girl on the snowy peak of Kunlun, named her Qi Nai, and made her his only disciple.
After ten years of education, he was her heaven and she was his calamity. The Imperial Master, who is as cold as the moon, gradually loses his guard in the girl's clear eyes; he is ignorant of the pure Qi Nai, and secretly develops feelings for him as they get along day and night.
On the day of haircut, with red makeup reflecting the snow, Si Luo glimpsed the calamity of death in the hexagram - the disciple he had carefully trained was actually the destiny to end his life. When the murderous intention arose, the cold blade was about to fall, but he felt a sharp pain in his heart. Only then did he realize that this girl had secretly learned the forbidden technique, using blood as a guide, and entangled the two people's lives.
"If Master dies, Qi Nai will never live alone."
In one word, trap his sword and tie his life. The law of heaven exerts pressure, and the roots of love are deeply rooted. Those who are ascetic are moved by their mortal hearts, and those who seek the truth are trapped in the web of love. Should we obey fate and kill the tribulation with our own hands, or should we go against fate and protect each other and go to perdition together? This master-disciple relationship, which begins with a tribulation, will eventually become a sadomasochistic chapter of life and death on the edge of love and death.
