In the middle of the battle, Cai Ming asks his son to draw the map and do the mission tonight. Cai Ming tells him that he owes his son a debt of gratitude and that he needs to get rid of the poison quickly. He tells Cai Ming not to worry about it, as they're out in the open and won't be bothered by anyone. He asks Cai Ming if he got any clues from the intruder, and Cai Ming says that he did. He also says that Cai Ming's guards are unreliable, and that they have a secret passageway that they can use to get in and out of the house. He says that they'll take care of the elderly, the weak women, and the children.
