I Am a Genius of the Holy See, Activating the Demon King's Counterattack System

Traveling to the Holy Light Continent, Karen has been a genius knight at the Holy See Academy for four consecutive years. He is about to take the graduation exam and his future is bright. Until the Demon King's Counterattack System was bound fifteen years in advance, it was clearly written on the panel - Thirty-five years old, frustrated, chopped down by the childhood sweetheart Saint, used as a male slave by the Demon King, drained of magic power by the succubus subordinates, and died tragically in the grave. The system requires him to defeat John, his best friend who plotted against him, within two years. And John had already drank the medicine—the debilitating potion was taking effect. Karen relied on the system skill "Fear Form" to forcefully remove the negative effects, but realized that the hate value was the key. He held Saint Angelica's hand, arousing the jealousy of all the men in the room, and earned more than a thousand hate points in three minutes. In the decisive game, Karen pretended to be overwhelmed by the effects of the drug, allowing John to get carried away and reveal all the conspiracy. When the hatred level reaches 10,000, he instantly removes his disguise, breaks John's sword with one sword, and turns the tables on the spot. Elena, the deputy leader of the Blue Moon Knights, made an exception and took him under her tutelage, and personally took him to receive the Sword Master inheritance.
