The Godly System: I Alone Possess the Ability of all gods

Leon was a genius cursed by talent. Others might have seen this as a divine gift, but not him. No matter what he touched—games, sports, academics, he mastered it effortlessly. But after conquering everything life had to offer, the world just became so unbearably boring. Then due to an unfortunate encounter with truck-kun— he died, and was sent into a dark void known as the realm of succession. After being forced to endure horrifying trials in the mysterious Realm of Succession, Leon was chosen by three ancient gods—Zeus, Hades, and Nyx—and reincarnates in the world of Oris, a modern fantasy world where humans wield supernatural powers through Essence and Resonance Cores. But sadly, the body he awakens in belongs to Theon Grey, a talentless academy student who had just been murdered. Now armed with a divine system, terrifying new abilities, and a power that should not exist in such a world, Theon must survive Starlight Academy, uncover the truth behind his death, and rise from the weakest rank to the pinnacle of the world. — Description from novelcodex.org
