Ji Zheng is a true blood descendant of the Lu family who was separated from them as a child. He spent eighteen years honing his martial arts skills at a boxing gym in the county town before finally returning to the Lu family. Lu Jingchen, who has lived with the Lus for years, fears that his comfortable life will be disrupted. He pretends to be weak and repeatedly creates divisions between the family members. Guided by his adoptive father's teaching, 'Stand on the side of reason, and you will never be the one at a disadvantage,' Ji Zheng relies on his own strength and his martial arts school's connections to uncover the layers of deception. When the truth finally comes to light, the Lu family members realize their mistakes and are overcome with guilt. Lu Jingchen eventually pays the price for his schemes and leaves the Lu family. With no desire to remain in a wealthy household, Ji Zheng chooses to return to the boxing gym in his hometown and embark on a new journey.
