Walking out of the forge, Brutus could not help the signs of mental exhaustion that began to set in.
'This body really is too weak'. He lamented.
The Monster Transmutation battle technique was one of the more dynamic battle techniques in Brutus' repertoire but it was definitely not the strongest, not even close.
The reason why he didn't use stronger battle techniques against the assassin was because of the lingering fear that his body won't be able to bear the stress.
And he was right, just the Monster Transmutation battle technique and his body was already feeling like this, totally exhausted now.
This was why after leaving Brutus II and Cedric Ironheart at the forge, Brutus walked straight to his mansion at the top of the mountain of this sect.
Entering inside, with his soul sense, he quickly detected that all 3 of his women were in their respective rooms already.
