In despair, Lin Fan's dormant "emotional devouring system" was activated. This system is not an upgrade in the traditional sense of killing monsters, but can convert other people's negative emotions towards the protagonist (such as contempt, anger, fear, despair) into experience points and special skills. When sarcasm turns into the perception of "insighting people's hearts", when anger condenses into "emotionally shocking" attack methods, when fear nourishes the stealth skill of "shadow invisibility", Lin Fan's road to revenge is no longer simply to fight violence with violence, but is full of ingenuity and reversal.
