When they return to the village, they find that many villagers have already died. They decide to check out the other villagers to see if they have also been poisoned. They find that 23 villagers are still alive, including the village chief and his wife. The third daughter- in-law also died, and the villagers are fighting again. The village chief is also dead. The two teams have split up to watch the villagers. The first team goes to the living-room to find out what the poison is. The stench of blood is strong in the room, and huan tells everyone that she received a hint that the poison was potassium cyanide. The second team will go to the chief and ask him about it.
