In the end, it was all caused by the stringent assessment system for fixed classrooms in the Ivory Tower.
To some extent, this overly cautious evaluation process, despite external infiltration, also effectively protected the school's ethos.
If an applicant couldn't secure approval from over thirty percent of the department members in a vote, they couldn't establish a foothold within this academic institution.
This led to a paradox: those who were hopelessly incompetent couldn't be helped, no matter the effort, while teachers with excellent academic foundations and teaching abilities hardly needed support from external forces.
Even if a few were occasionally sent in, they would quickly be assimilated by the inherent cohesion of the Ivory Tower itself.
