Lu Ciyuan heard his father's trembling "Zhiyuan" before his death, which instantly exploded the entire family's secrets. He has been regarded as the legitimate son of the Lu family since he was a child, but he does not know that he is a substitute, and his real blood is Cheng Zhiyao, an orphan adopted by his mother. When the will was made public, the Lu family's century-old legacy was handed over to a name that had never been recognized. Lu Ciyuan pressed forward step by step, but Cheng Zhiyao remained as silent as ice. It's not that he doesn't want to argue, but he's afraid that once he opens his mouth, even the last bit of false warmth will be wiped out. What is torn apart by blood is not inheritance, but two souls nailed into the abyss by fate.
