Bam! Bam! Bam!
Rex's fists smashed golem monsters until they bled.
The only time when his fists got to rest was when he passed out but yet his rest time didn't last long since the pain of the strength steroids always woke him up just a few minutes or hours after he slept.
At this moment, he was like a slave that was enslaved in a recurring timeline of masochistic training where he had to try his best to get stronger.
As the Golem monsters' strengths increased, so also did Rex's strength increase though he barely noticed it as the titanic struggle continued.
Throughout, his screams of pain were the main constant that never changed.
Hiding at a safe location on top this training chamber, the Tiajutsu expert ancestor Bam watched the proceedings with a calm look on his face.
"His hand-to-hand skills are average at best but it is to be expected since he is a swordsman, what is really incredible is his vitality".
"Even among same-graded vampires, his vitality is impressive".
