The naive Second Highness of the Demon Clan saved a young boy of his own age eight hundred years ago, but he didn't know that he was the natural enemy of the Demon Clan. It was discovered after being hidden for eight hundred years and became famous. He fought tooth and nail to protect the demons and made them hate him. In the end, he was plagued by illness and dragged around a medicine jar every day. Three hundred years later, the demon clan reappeared and prepared to capture the demon clan. By chance, he met A Yan, whom he had raised for three hundred years. He became the Demon Lord, but said that he did not know His Highness Hanhan. He didn't expect that when they meet again three hundred years later, they can only look at each other.
