The top-tier professional player Lis woke up to find himself having crossed into the “Divine Revelation” game, becoming a Viscount enamored with magic. Knowing that he would soon face a continent engulfed in war smoke, grand otherworld expeditions, the mysterious decay of the World Tree, and the constant threat of Abyss Demon invasions... Lis admitted he was a bit panicked. ...... Fortunately, the game system was still in place, and he still possessed the “All-Purpose” Talent. With the memories of his past life, he switched his class to Arcanist, analyzed the Element Model, reshaped the world’s rules, and step by step ascended to that supreme throne. ...... Players complained about him, “This boss is too perverted, he can even grow stronger, we protest!” Elves worshiped him, “Lord Lis is the strongest Divine Favored, he has brought peace to the world.” Mages praised him, “He is the pioneer of magic, as well as the Guardian. His revered name is Lis Kane, He is the god of the arcane.”
