Was Li He, Li Weixuan's grandfather, the core person handling the aftermath of the incident back then?
It makes sense, given how long he held sway at the Academy.
As an administrative figure, his strength might not suffice to lead explorations, but in the event of a crisis, he would undoubtedly take charge of emergency measures.
However, from Cass's account, the entire aftermath work of the incident seems rather suspicious.
The reason Cass stayed behind is quite plausible, even interpretable as a good intention to keep him from danger.
After all, a group of elite got wiped out like that, and according to Cass's previous description, at the time, his talents and achievements were even slightly below Kaldora's.
In the face of significant risk to even demigods, leaving someone like him as a core of the new generation to keep some fire for the Academy is quite a normal move.
But the behavior after returning, no matter how you look, suggests hidden reasons.
