Because he had the heritage of the ancient Demonic Emperor, Demonic King Zhuo Yifan met the misfortune of being betrayed and killed by his trusted disciple. After being reborn, his cultivation went back to zero and he was trapped by a demon in his heart, and has no choice but to become the steward of the Luo Family's lone eldest miss. From being a Demonic King to being an insignificant steward of a broken household, how would he get along with his "heart demon eldest miss" and what power would he gain in order to lead himself and the declining family to rise back to the peak of the continent!

[Side Note: A more accurate series name translation would be "The Steward Demonic King", as there's a level above King ”皇“, dubbed Emperor “帝”. The steward part is as important as demonic king as both played a huge part in the MC characterization throughout the series]
