In the neon-lit Linhai City, emotions are not only human inner fluctuations, but also "energy weapons" that can be manipulated. A small number of awakened "emotional sword-wielders" can use the power of emotions to kill demons and demons, or they can turn into "emotional aberrations" that devour everything due to loss of control. The two major organizations, the Lawful Society and the Free Alliance, have long been fighting for the dominance of emotional energy.
Ling Ye, an ordinary college student who just graduated, accidentally awakened due to the old sword left by his grandfather, and became a special sword wielder who can purify negative emotions. He not only has to deal with the rampaging aberrations on the streets, but also has to deal with the rigid control of the Lawful Society and the crazy plundering of the Free Alliance - the senior leaders of the Lawful Society covet the "emotional core" fragment in his hand and want to use it to control the emotions of all mankind; the careerists of the Free League incite negative emotions and regard human lives as pawns.
Using empathy to understand the opponent's weaknesses, and using the "Soul Sword" to transform despair into courage, Ling Ye has gradually grown from a novice forced to protect himself to the key to stirring up the storm. He unlocked the emotional tactics left behind by his grandfather, integrated the forces of justice to form an "emotional protection team", and when the global "emotional storm" came, he shouldered the burden of protecting the world, and in the choice between human nature and power, he found a path of balance that does not plunder or suppress.
When emotions become the key to dominating the world, is the sword in Ling Ye's hand a light that splits the darkness, or a fire that leads to destruction? The ultimate showdown concerning human emotions and survival begins in the night near the sea.
