Your Highness, Don't Be Angry. You Can't Rush Your Ascension.

His Highness the Demon King, who failed to transcend tribulations and ascend four times in a row, was struck by lightning until only one demon pill with no thoughts and senses remained, and fell into the human world. The demon world would be in chaos without a Demon King sitting in charge. For the sake of a few powerful repair pills, it is better to go to the human world to look for His Highness the Demon King who has declined to the extreme!
