The Ministry of Environment and Ecology strongly suspects that the cause for all the environmental and ecological changes lies at the core of the Serevian Plateau based on the triangulation of seismic radiation, and extrapolating from the measurements of the intensity of changes across the entire region.
That was where Rui came in. The core of the Serevian Plateau was too dangerous to even grade-nine Martial Apprentices. Only grade-ten Martial Apprentices were capable of completing the missions. Furthermore, the number of grade-ten Martial Apprentices who had mastered something like Seismic Mapping was extremely low. However, that wasn't the only reason Rui was ideal for the mission.
"Fauna Flow must have been a deciding factor as well," Rui murmured.
