Lin tells Gucheng that he will never use his blood to poison him again, because seeing him suffer breaks his heart. Lin tells him that if he still wants to do so, he can use the old method, but if he wants to use the new method, he must use the "primitive" method. Gucheng tells Lin that his father has found out that Lin's mother died due to a blood loss due to childbirth. The doctor in charge of giving her mother's pregnancy check-up had said that her mother had always been in good condition. Lin was spreading lies the entire time.
