On the day that his father kicked him out of the house as a poor relative, Lu Zheng realized that he was the real young master who had been transferred. After twenty years of forbearance, he climbed up from the sweat and blood of the construction site, relying on a pair of fists and an old contract to approach the core of the Lu family step by step. The adoptive father is silent, the stand-in young master fights back wildly, the lawyer hides the truth, and his biological father is wavering between atonement and fear. When the will is exposed and the DNA testimony is played in public, the ownership of billions of dollars in property will be rewritten by the hands of this man who has been humiliated by the entire family.
