In truth, Gu Shanhai's concept for the Heart Demon Dao Soldiers revolved around one thing: disgust. When the enemy struck a Heart Demon Dao Soldier, they would suffer a series of backlashes, as well as face their own burgeoning desires and emotions. When the Heart Demon Dao Soldiers counterattacked, they would directly utilize these desires and emotions to inflict massive damage and additional harm.
The enemy would feel disgusted attacking the Heart Demon Dao Soldiers, but when the Heart Demons struck back at the enemy, not only would it be disgusting, but it would also cause severe damage.
Moreover, all their abilities were specifically designed to mess with the opponent's state of mind. Fighting too much with Heart Demon Dao Soldiers, or being attacked too much without dying, could not only lead to a mental breakdown but might also result in decreased intelligence.
