The next time they try to pass through a second karma hall, they'll have to rely more on their strength than ever before. They'll also have to worry about how they're going to judge whether or not they've passed through the first karma hall correctly. Finally, they decide to send a sword spirit ahead to scout the area around the stone. The stone is 30 feet long and 30 feet wide at each side. The only problem is that the stone is rolling at a fast speed, which means they can't get across the second hall in time.
