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.”

The youngest, silly fourteenth son of the Yan Emperor had reached the age where he should be given a separated territory now. He rejected the wealthy land, neighbouring the capital city, and instead chose the wildest land in the western region— Liangcheng. Everyone shook their heads and sighed. A fool is indeed a fool. If you go to Liangcheng, you will be killed by barbarians in less than three to five years.

One year later, the watermelon presented to the Emperor as the tribute from Liangcheng in the west was sweet and crispy. There was no one in the palace who did not love it.

Two years later, Liangcheng presented corn as a tribute to the Emperor. The yield was high, and the taste was good. No one in the country could resist liking it.

Three years later, Liangcheng defeated the barbarians and presented their prisoners in front of the imperial court. The people of Yan were excited and their morale was greatly boosted.

Four years later… Everyone said that the fourteenth prince Mingyu was a fool, while the little fatty Yu, who transmigrated with the golden finger, chuckled. Let’s see how you guys look at this fool build his own territory, then.
