He was no longer a research assistant; he was a tenured official researcher, and so, if he applied to a Beast Tamer University in another security zone, he would face a great deal of trouble in the future.
He couldn't possibly give up his hard-earned official researcher status just to go to another Beast Tamer University, nor could he frequently travel back and forth between two security zones. Thus, the best choice for him was to stay within Mountain City University.
Being both a tenured researcher at the Institute of Evolution in Mountain City University and a student of Mountain City University was the best of both worlds.
Mountain City University was already among the top five Beast Tamer Universities within the Yan Huang Alliance, and its strength was not weak. When all the top institutions were compared, the differences in strength among them weren't too significant, so there was no need to insist on being at Jinghua University, which was ranked first.
