Ten years ago, Lu Chuan, the legitimate eldest son of the Lu family, left home and went overseas alone to cultivate. Ten years later, he has become the top tycoon "Lord Lu" whom overseas dignitaries bow to. At the same time, he possesses mastery in ancient martial arts, peerless medical skills, the ability to deduce heavenly secrets, and refine supreme treasures. After receiving a plea for help from his mother, Lu Chuan returns to the Lu family, only to find that his three younger siblings each possess cheat codes such as a system, medicine immortal inheritance, and martial god reincarnation, making them rebellious, arrogant, and dismissive of everyone. Thus, while settling scores with the family's enemies, he uses absolute strength to discipline his younger siblings one by one, ultimately uncovering the secret threatening the family in the shadows.
