Gao Guang's connection with Otto had suddenly tightened. It wasn't that Gao Guang and his teacher had genuinely grown closer; rather, the situation had forced it.
Edelweiss was far too mysterious. Although many were using the Dark Web, very few knew about Edelweiss, the force behind it. Therefore, Otto was the only one he could discuss matters related to Edelweiss with.
"Teacher, I've found the person who betrayed me."
"Betrayal, by someone close to you?"
The term 'betrayal' had a specific implication; being harmed by a stranger was just harm—it certainly wasn't betrayal. Thus, Otto immediately concluded that someone close to Gao Guang had betrayed him.
