Wen Qinghe, the holy son of the Immortal Sect, traveled around the mortal world and picked up Li Su, a young man who had become a beggar (xiu)
He didn't know the young man's identity as a demon, nor did he know that beneath the gentleness in his eyes, there was deep-seated hatred for the Immortal Sect.
Li Su relied on the secret spiritual power of the necklace and his forbearance step by step to become one of Wen Qinghe's direct disciples.
The water mirror bestows spirit, and the divine sword recognizes its master.
The closer he was to the road of revenge, the harder it was to ignore the tenderness in his master's eyes; Wen Qinghe treated him like a jewel, but when she caught him having a secret meeting with the demon, she killed the demon with her own hands - and cut off the last trace of the boy's pretense of obedience.
Li Su, who left home in anger, exposed his demon body when the necklace lost control and killed someone. When Wen Qinghe's sword pierced his chest, he saw the pain in his master's eyes, but he only thought it was the immortal's instinctive hatred for the demons.
Five years later, Demon Lord Li Su returned under an assumed name and lurked beside Wen Qinghe as a civilian. He originally wanted to cause a bloody storm, but he got a glimpse of the truth through repeated trials.
When the hypocritical mask of the Immortal Sect is torn apart, the two people who were once master and apprentice, but now have opposing views, will eventually hold swords side by side.
Whether it is immortal or demon, hate or love, the dust has settled in that revenge for the truth and each other.
Purpose: Break the prejudice of labeling and explore the true meaning of the nature of good and evil and emotions - immortals may not be purely good, and demons may not all be evil. Under identity and position, individual choice and the temperature of the human heart are the foundation for transcending opposition.
