A useless prince, yet brimming with kindness and compassion—his smile as warm as sunlight, illuminating this darkened era.But that was merely a mask, hiding the poisonous and mad nature beneath.A monster lurking behind a gentle shell.A system that feeds on stolen Heroines.He will outplay destiny—and rise as the world’s ultimate villain.

As soon as Lu Xuan woke up, he became an ordinary spiritual planter in Sanxiufang City, guarding a one-acre three-point spiritual field, and living in the world of practice.

Harvest a Xuan Chong vine and get a share of Yin Xingsha.

Harvest a Youquan flower and get a piece of Zhiyan Pill Recipe.

…

“I just want to farm quietly.”
