The lunatic tells the group that they should go investigate the area and find the dragons. He also tells them to be careful of the poisonous plants in the area, as they might be able to catch up with the dragons and kill them. The group finds the corpses of three yuan dragons, and the captain tells them that the dragons are testing their combat skills. The captain says that although the dragons' attack power is very high, they are limited in their moves. He sends the group to find the coordinates, and ten minutes later, the students find the corpses. The corpses are not pure gold, but a piece of gold. The impurity percentage is 40 percent, and after 2 hours the corpses can produce tons of rare metals. They also find a big dragon coming, which is equivalent to a land dragon in terms of strength. The leader of the group tells the others to get ready to attack. He tells everyone to retreat back to the base.
