Rui did not stop there. He went on to challenge three more guardians in the following days.
He defeated all of them, but not a single one of them was able to defeat him.
Many of the sharper guardians that had been following his streak had managed to notice some patterns in these duels.
They noticed that he was indeed aiming for guardians with lethally offensive Martial Art, but also, he had also gained some new healing abilities that allowed him to heal from the lethal attacks that they dealt out.
Many put two and two together and realized that the reason that Rui had chosen them was merely to test something new, most likely.
That was even more surprising than if he just fought them to get to higher and higher chambers.
It showed that, unlike most guardians, Rui did not necessarily conform to the norms. He didn't make slow increments, increasing his rank bit by bit.
Rather, he seemed driven by progress in his Martial Path more than progress in aiming for higher chambers.
