The narrator explains that the demon battlefield was the place where many demons died during the ancient demon's great war. During the war, people sealed the souls of the demons in the battlefield so that they could not harm humans. The jade pendant that grandpa gave him belongs to his mom, who gave it to his father when they left. They must go there to find out what happened to their parents. The narrator says that the battlefield is a dangerous place, but that he will come with them after finishing his work in the moonlight city. He reassures his sister that the phoenix will protect him. He promises to return once he is done with his work. The vice-captain of the burning cloud tells the narrator that two strangers have followed them to the battlefield, and that no one has survived. He says that they are not going to team up with them at the moment, because they are more dangerous than they think. He tells the girl that she should thank them for inviting her, but she is not interested in their offer. She says that she can protect her sister by herself. The captain says that he can feel the spiritual qi flowing in the cauldrons, which is a perfect bait for demons. He warns her to leave them to him.
