Gu Fei was considered quite fastidious. Since he could not teleport back underground, the moment he got out of the tunnel, he took out another scroll and made note of the coordinates outside before sprinting his way back to Yunduan City.
Even though Gu Fei was questing in an irregular manner, that did not mean that he was unclear as to how to go about doing quests in the correct manner. Sometimes, it was merely due to his aversion of the process being troublesome which was why he often left a trail of bloodshed by carving his own way with his own methods. The freedom that existed in Parallel World meant that it allowed players to run wild. It was merely that he had simply too much freedom after using the magical air bubble to dive down to this highly suspicious location. Even if there were not any city assaulters that ended up causing trouble for him while he was down there, Gu Fei felt it was impossible for him to deduce the necessary clues he needed from that place.
