After Taking This Case, I Turned into a Prey

Losing control? No, they really want to kill you. Since "emotional particles" pervaded the world, human emotions have become entities. And I, Lin Yan, an emotional hunter, make a living by catching these emotional remnants. Until I took over a bizarre suicide case of a rich man - there was no murderer at the scene, only an extremely pure "crystal of joy". He was laughing to death with his own happiness. The black market sells emotions, technology companies harvest them, and my dead partner warned me in my memory. Now, everyone says I am the savior. But I know that when the seven emotions accumulated in my body explode at the same time, I will be the ultimate weapon to destroy the world.
