After Years of Widowhood, the Demon Lord Turns Over a New Leaf

Luo Wangshu, the sect's senior disciple, is supremely talented and unmatched in bearing. Unable to watch the people suffer and the sects be falsely accused, he stands alone against one deadly trap after another while all the immortal sects hold their tongues, and personally beheads the tyrannical, despotic Immortal Venerable. From then on, all the sects pledge themselves to him, and the world praises him for slaying the tyrant. In response to the people's wishes, Luo Wangshu ascends to the honored seat. Countless praises and supreme glory all belong to him.

If such a person has any regrets, there is probably just one: he was widowed at a young age.

After his junior brother Yan Qi died, Luo Wangshu was never the same again.

In the past, he upheld the righteous path, and people believed that "evil can never prevail over good." But when he fell and became a demon, the cultivation world learned that whether those four words hold true ultimately depends on who stands on the side of "evil."

The revered champion of the righteous path became the only Immortal Venerable in thousands of years whom no one in the cultivation world could destroy, a festering blight upon them all.

Every sect and faction hated him, loathed him, and regretted everything, but no one in the world could defeat him. They could only let him run rampant. Nine hundred years passed. The world believed that the Immortal Venerable ruled the land, unaware that when night fell and all was still, Luo Wangshu would crouch alone before Yan Qi's grave, wiping away tears as he poured out his grievances.

One day, Luo Wangshu had finally had enough of this seemingly endless life of widowhood, and took his own life...
