Overcoming Poison

Due Hall was destroyed overnight, and was called a plague to the outside world, but in fact it was silenced - because after they refined military poison for King Jing'an, they found that the poison was used to massacre civilians who surrendered, and wanted to withdraw. Su Du is the last descendant of Due Hall. Before his death, the master pushed her into the secret passage and left only one sentence: "Survive as a substitute for marriage - Prince Jing'an's Mansion is the only place that can protect you." She married into Prince Jing'an as the legitimate daughter of the Liu family. On their wedding night, she discovered that the eldest son, Xiao Heng, was coughing up blood - it was not a disease, but the chronic cold poison "Shuang Gu San". This kind of poison can only be refined by Due Hall. The person who poisoned him was Xiao Heng's biological father, King Chuhuan of Jingan. Xiao Heng has been poisoned since he was three years old and has been raised for twenty years, not because of his father's love, but because his mother left a secret edict before she died, which requires his blood to open. King Jing'an raised him like a key. Two people who were poisoned by fate met in a chess game. Su Du used his own blood pressure to control Xiao Heng's cold poison, but the cost was that his own poisonous power backfired more and more severely; Xiao Heng secretly managed his power, waiting not only for the detoxification, but also for the day when the situation would turn around.
