Those Years as a Slave in the Fairy World

"Have you ever thought that the joy, anger, sorrow, fear and disgust in your heart will turn into spiritual power - in this world, emotions are the only hard currency." This is a world of immortality where emotions are the power of immortality. Emotions are not naturally cultivated, but are generated by the heart of every living being. Immortals extract the emotions of joy, anger, sorrow, fear, disgust and other emotions from mortals, release their majestic power, and forge unique immortal weapons. Wu Ji, on the other hand, is just a love slave and a human mine, and can only be reduced to the source of the immortal's emotions. In addition, Wu Ji was born without a heart and was not even qualified to be exploited. He watched his loved ones being humiliated to death, but he could not feel any emotion at all. When he was about to die with his mother, he was discovered by an ancient powerful emotion because of Wu Xin's special nature, and forged a heart of his own for him. A few years later, Wu Ji stood on the top of the tower, pointing his sword at the sky. "Tianlu, if you are still stubborn, then let's see how I open a new sky!"
