Lu Chengyu|A modern corporate executive who kills decisively (attack). After time travel, he is resourceful and strong in dealing with things. He does not worship the imperial power, is calm and sinister to the outside world, and only loves and controls the emperor.
Xiao Jingyuan|The tyrant emperor of Dajing (Shou), with a cold and murderous appearance, intimidating the government and the opposition, he was put under house arrest by powerful ministers when he was a child and suffered a lot of hardships. He lacks love and sensitivity in his heart and longs to be controlled and accompanied.
Lu Chengyu accidentally traveled through Dajing by touching an ancient ancestral book, and happened to save the emperor Xiao Jingyuan who was in danger of being assassinated. Everyone in the civil and military dynasties feared the tyrant like a tiger and tried their best to flatter him. Only Lu Chengyu saw through the fragility behind the emperor's violent outer shell.
In the court, he cleverly used modern ideas to rectify the bad government, successively foiled the plans of the Grand Tutor Shen Yanzhi, eradicated the chaos in the family, and helped Xiao Jinyuan regain imperial power; deep in the palace, he strictly controlled His Majesty's bad habits, and carefully and gently healed his childhood pain.
The iron-blooded emperor who originally said he was one and the same gradually lost his sharpness and arrogance, obeyed everything, and stayed by Lu Chengyu's side all day long.
Treacherous ministers are framed and shocking palace changes occur one after another. Lu Chengyu protects himself with his plans and his body. Sitting on thousands of miles of territory, Xiao Jinyuan bluntly said that the world can be given to the world, but only one person can entrust it with all his heart and soul, and the two work together to create a prosperous age.
