Du You chose a difficult path, one marked by many mountains, and that's why no one else chose this route.
Previously, in his territory, Du You had obtained a Communication Orb that could facilitate a limited range of communications. It wasn't very convenient, but it had the benefit of being able to communicate across extremely long distances. It was said that in an average world, one could communicate from one end of the world to the other.
After that, any event he encountered on the road could be recorded with a wristband and then selected clips could be sent back via the Communication Orb. The academy would compare these and record merits after verification.
