Alex was intentionally stalling for time; that was the reason for him wearing a thoughtful look on his face, but no one knew about it.
So, everyone thought that maybe he was really considering changing his decision.
Demon generals and the ancestor didn't have much change in their emotions since it was not that they were very excited to get a new general candidate.
They already had Alex, who had much greater potential than any general could ever hope for.
He, who was just 18 years old, was already a legendary ranker—one that could fight toe to toe with four mythical ranked beings.
What more did they need to say about the monstrosity named Alex?
Yeah, if Alex wasn't summoned, then they sure would've been excited about having a new demon with the potential to become a general among themselves.
So, in a way, Alex was the one who destroyed the poor protagonist's plot even without realizing it.
