What could the Martial Union want from him so urgently? Rui wasn't sure, but there were several general possibilities. They wanted something from him obviously, the only rea possibilities were his Apprentice Realm combat prowess and his knowledge.

Why would they want his Apprentice Realm combat prowess urgently? There was no shortage of Martial Artists in the Academy, unless the town of Hajin had suddenly been attacked by a horde of monsters or something, it was impossible for them to want his Martial prowess this desperately.

That left information, what information did he possess that the Martial Union didn't? Well, there was his scientific and combat knowledge and research from Earth, but obviously that was not why they were calling him. There was something that they knew he knew, they wanted.

Information about the latest mission? This was the only real possibility as far as Rui could think of. There was something about this mission that the Martial Union needed him for.
