Khan's days went back to being extremely busy, but an important event preceded the return to that routine.
A simple check-up in the medical bay the morning after the talk with Cora was enough to award Khan with a second star on his right shoulder. Then, a few bystanders noticed the change in his uniform during his walk back to the flat and spread the news.
By the end of the morning, everyone in the camp had learnt that Khan had become a second-level warrior. Doctor Blackburn had even updated his profile, so anyone could check that the matter was true.
Khan was only at the beginning of his third academic year, but he had already become a second-level warrior. Moreover, he had accomplished all of that without synthetic mana or a long period of isolation.
