In this chapter, Dr. Rivers and the others discuss the Four Realms. They've heard rumors that they're powerful, but they've never faced them before. The Four Realms are said to be from the same mother, and their minds are the same. The Moser sect trained them to be a tech combo, which means they can fight together. But they can't all fight at the same time, because their personalities are so different. For example, the little dwarf is fierce, reckless, and brainless. He's also a little too smart for his own good, but he's still smart enough to beat the other three. The other three are also smart, but not as smart as the other two. The coward ghost is the last of the four, and he was beaten down by the others because he didn't want to fight them. The four of them, Rivers says, are the toughest bosses in the whole world, and they were able to beat them.
