Inside a large underground palace, a group of people touch lightly. The walls are cold and the temperature feels very cold. The air is so dense that it's hard to breathe. It's a humid place, and the kids are afraid to go in there. They're afraid that the bureau of Chinese martial arts wants to put them in such a creepy place. The kids decide to go check out the stone altar and find out what's inside. They find a coffin with a pair of fake armor on it. The coffin is full of stuff, but no one has found it yet.
