Wei Wu Xian and Lan Wang Ji are two completely different people from two different worlds. Lan Wang Ji is from the prominent Sect of the Gusu Lan. Due to his great achievements and reputation, he gained the title Hanguang-Jun, which means the light holder. He is seen as a hero, the role model of everyone in the cultivation world and is known to appear wherever chaos is. While Wei Wu Xian, the Yiling Patriarch who uses demonic cultivation, is a name that fears everyone. He has done many heroic things in his life, but also really cruel ones, such as killing thousands of people and even causing the death of those who saw him as family. However, the two who are totally different in nature as ice and fire, are good friends who consider each other as soulmates.
In the end, Wei Wu Xian was "killed", after he became too evil for the world to exist, by the only survivor of the Yunmeng Jiang Sect, Jiang Cheng, who was once like a brother to him. At least that is what the legend says. Sixteen years after his so-called “death”, Wei Wu Xian suddenly reappears at the Mo Village.
Between the boundary of good and evil, is Wei Wu Xian really as evil as the legend says and is Lan Wang Ji really that righteous as people claim him to be? And how much of the legend is actually true?
