A pair of twin brothers have embarked on completely different paths since they were unexpectedly separated when they were infancy.
His younger brother Wan Haoyue is still the son of the leader of the Tianling Sect, which was originally called the "Devil Sect" by the righteous people in the Central Plains. He is the distinguished young leader of the Tianling Sect. He has a father who is strict but yet loving, a mother who dotes on him, and a lover, Lai Xiao, who, although occasionally evil-minded, actually holds him in the palm of her hand all the time. His life has been smooth sailing and as sweet as honey.
Another child, whose original name was Wan Changfeng, was adopted by Qin Yi, the head of Lingyun Sword Sect, a famous upright sect whose mission was to slay demons. He was renamed Qin Chenbi and was taught to be a gentle and submissive man. Almost all decent people strictly guarded him because of his background, and even refused to teach him any martial arts on the grounds that he was born weak. Coupled with the torture of congenital illness, Qin Chenbi's frown almost never relaxed.
Wan Haoyue's only worry has always been that he often gets angina pectoris for no reason due to his twin brother's involvement. This has also been a headache for Lai Xiao. Finally one day, he couldn't bear it anymore and decided to kill Qin Chenbi with his own hands to end his lover's pain.
But when Laixiao successfully infiltrated the Lingyun Sword Sect, she was unknowingly attracted to the man who looked exactly like her lover but had a completely different personality...
Between old love and new love, how should Lai Xiao choose? Or, could he just accept the order?
