In an underwhelming fashion, he fell to his knees again in exhaustion.
Splash!
Rex didn't count how many times he fell into the shallow water out of exhaustion, but it's definitely a lot. But compared to the ones earlier, this time, he has a satisfied smile on his face thanks to his achievement.
Despite his exhaustion, he could feel a cool sensation breezing his body.
Having unlimited stamina in this realm thanks to the Countess who helped him recover doesn't mean he's completely fine, his mental takes a huge hit in this place. It was only his unyielding perseverance that helped him get by fine.
Put anyone in this realm for even 15 minutes, and they would go insane.
This realm is specifically made to torture the Countess through the pain that mortals feel.
Almost like an extreme version of sensory deprivation.
