Shen Qiyun, the youngest executioner in the Tianshu Academy, did the thing he regretted most in his life - on the execution platform where thousands of swords pierced his heart, he blocked the fatal sky thunder on behalf of Xie Buyu, who had rebelled against the devil.
Twelve years ago, Xie Buyu was a young genius who ranked first in the three levels on the Trial Peak, and Shen Qiyun was a steady and steady new star of swordsmanship under the leader.
They died side by side in the wind and snow in the north, silently confronting each other on the edge of the cliff where good and evil are separated. One could not bear to be killed, and the other refused to leave. Until Xie Buyu stole the Demon Sword, massacred Southern Xinjiang, betrayed his master, and became the number one demon on the Righteous Alliance's kill order.
Everyone in the world knew that his crime was unpardonable, but Chen Qiyun knew that the half-inch deviation of his sword was intentional.
After the thunder, Xie Buyu escaped from the Magic Locking Tower and appeared in his courtyard late at night, saying, "I just want to ask you - you said you wanted to kill me with your own hands three years ago, why didn't you do it?"
The pursuit of justice is launched again, but the deceased in southern Xinjiang has another secret. When the truth hidden behind the murder surfaced, Shen Qiyun discovered that all the charges on Xie Buyu's back pointed to a secret related to him.
Good and evil do not coexist, and deep love does not violate the rules. But what if the line itself was wrong from the beginning?
