On the day of his father's funeral, Lu Fen burned the will in public. What came out of the ashes was not the distribution of property, but a letter of confession that had never been made public. Jiang Jin stood in the corner of the mourning hall, his fingertips holding the key that his mother had given him before she died - the basement door that had been locked for twenty years was finally opened in the light of the fire. The two are half-brothers, one was raised in the sun and the other was buried in the darkness. Lu Fen thought that burning the will would cut off the shackles, but he didn't know that Jiang Jin was already in the dark, spending twenty years of silence in exchange for evidence that could subvert everything.
His father's will was burned, and the family was shocked. The lawyer read out the backup documents in public - all assets belong to the "true heir" Jiang Jin. Lu Fen asked angrily, but Jiang Jin said softly: "Do you remember when I was seven years old, I was locked in the basement for three days, but you were eating cake in the banquet hall?" The surveillance video was exposed, and the father forged a paternity test before his death, demoted his biological son to a servant, but promoted his illegitimate son as his heir. Jiang Jin opened the safe, and inside were all the ransom receipts for Lu Fen's childhood kidnapping, as well as recordings of calls between his father and the traffickers. Lu Fen knelt down, his hands still stained with the ashes of the will. Jiang Jin turned around and said, "Now it's your turn, taste what it's like to be used as a tool." The funeral was over, the brothers turned against each other, and the blood debt had just been settled.
