After Rio finished asking all his doubts to the system, he lay on his bed again, closing his eyes trying to free his mind and think about what to do with this system.
He had planned to kill all his enemies who would plot against Rio or his family before the plot even begins and they start getting powerful, but this system's arrival might force him to change some of his plans.
If he trusts the system then he should only act after the plot begins to get more points and rewards, but if that system is a lie then he would have to deal with all his enemies and protagonist's stupid luck, though he might have some advantage over them due to his future knowledge, but as many people said against pure power all schemes and plans fail, Leon with his halo becomes the strongest person alive in the novel. Author made him so op that he never even wrote about his fight with the final boss and just said Leon won and had a happy ending.
