More than four thousand years ago, the human race finally won the final victory in the war between humans and demons. The fifth demon city, Amano City, was massacred by the Celestial Master Alliance. Wanling, a member of the demon-catching tribe, betrayed the Celestial Master Alliance in order to save hundreds of thousands of innocent and weak people in the city...
Four thousand years later, Wanling was reincarnated as Wei Lan, the descendant of the Wei family of the monster-catching clan. Wei Lan is a rookie heavenly master who has always been secretly in love with Chang Xi, a genius demon catching master. They are two very different people. One only dares to love secretly, and the other can only guard silently... Until this day, Demon Emperor Qi Yuanshan returns to the world. He is powerful and domineering, but in front of Wei Lan, he becomes yandere and childish, and shamelessly pesters Wei Lan all the time, just to renew his relationship with Wei Lan.
At the same time, Zhuang Shaoluo, the biggest villain of the demon clan, colludes with Yao Zun, the scum of the demon-catching clan. One intends to seize the position of demon emperor, and the other wants to dominate the world... Wei Lan gradually develops subtle feelings for Qi Yuanshan during the demon-catching missions... She seems to have fallen in love with both men, how should she choose...
Motto: True love is priceless, be brave for love.
