If he was going to lose his mind and fall apart just because he failed to establish his prestige as a professor in front of the freshmen, wasn't that a bit too thin-skinned? Was Professor Guderian really such a fragile guy psychologically? Didn't Professor Manstein and Professor Schneider constantly tear him down?
"No, it's about the White King's bloodline... How could I have forgotten, it's the White King's bloodline..." Professor Guderian's face went ashen, looking as devastated as if he had lost both parents. "I have absolutely... zero experience educating students with the White King's bloodline!"
This was the real reason. What left Professor Guderian utterly disconsolate was neither the fact that Erii showed zero reaction to his test, nor the blunder that made him look like a fool in front of students, nor even Lu Mingfei saying he had gone senile. Guderian's psychological fortitude in those areas was frighteningly strong; otherwise, he wouldn't have lingered at Cassel College for so long just for the title of "lifetime professor."
