"Yes, my men met three of them, all of whom acted alone, unlike the herds on Earth's surface. All three of them were at or above level-seven," Lan Lu nodded and said with a serious look.
His words made the other two glance at each other and wear a serious look as well.
All three creatures that Lan Lu's men met were at level-seven or even above. His men didn't reach the bottom of the underground world, meaning that stronger creatures might exist deeper underground. Monsters at level eight or even nine could exist down there. The team which would be sent underground this time could very likely be unable to come back. At the very least, it would be a very dangerous mission.
