The Most Miserable Villain in History

He is the eldest son of the Demon King. He has a prominent position, above ten thousand people, and has overwhelming power. He was well-dressed and well-fed, and he was so majestic that no one dared to offend him. He is regarded as the successor of the future Demon King and attracts everyone's attention! He is arrogant and domineering, and everyone in the demon world takes it for granted! Until one day, in order to prove that he can become the king who rules the world, he happily accepted the test of his father. With arrogance and domineering, he took off his magic power and embarked on a one-year conquest of the world. On that day, he entered the world with luxurious clothes, countless gold cards, and the holy book "Guide to Conquer Humanity". Things took a turn for the worse. That day, he lost almost everything and suffered his first severe beating from human society. And this is just the beginning.
