198 Falling Walls

The day after Robin's conversation with Sage Albert, he summoned Caesar, Zara, and 4 mid-leveled knights to his palace, as the seventh session began...

"AAAAAAAAAAAAHHHHHHH"

After a few months' absence, Caesar's screams shook the administrative area again

But it was nothing compared to the first few times.

After Caesar experienced the gray flame and knew for sure that he was getting stronger, and after going through this painful experience a few times already... 

his screams became noticeably milder, his resistance became weaker, and not even once from start to finish of this session did he beg Robin to stop

Another reason is that Zara has become level 12 and the amount of energy she is pumping into Caesar's back has also increased significantly!
