Lin Zhaozhao held the copper seal that was his mother's relic and opened the iron letter and blood letter under Jia Yucun's eyes. He discovered that his father's deathbed letter and the second name were actually written by Jia's mother during her lifetime.
She used false accounts as bait, set up a game within a game, and tore off his mask of integrity in public. Little did she know that there was a third unsent letter hidden at the end of the blood letter.
Every counterattack involves risking one's life, and the person who really controls the situation in Jinling may never have been Jia Yucun, but the old lady of the Jia family who has long since died of illness.
