The Youth Elite Team received a report from the SRC that the seabed protection net was abnormal. In order to check the seabed protection net, the Elite Team dispatched the universal exploration machine, the Tek exploration machine. Musashi and Fubuki drove the exploration machine to the vast ocean. Under the operation of the two, the repair work went smoothly. Unexpectedly, the claws of the chaos virus had quietly reached the seabed. The docile sea beast Jerga became ferocious and attacked the exploration machine fiercely. Due to the damage of the oxygen cylinder, Musashi and Fubuki fell into a crisis that they could not escape.
