Shiba felt exhausted.
His attack seemed simple, but he had put all of his strength to make it.
However, it hadn't been enough to kill Bea.
Shiba felt that he failed, but he didn't know that although it was true that Bea survived, her soul had been injured.
Injuries to the soul were extremely hard to heal, and with a harmed soul, one couldn't become a Law Master, and even normal training speed would diminish. If a wound on the soul was too heavy despite not being heavy enough to destroy it, the person might no longer advance a single level.
The Ugador Clan saw Bea as someone with the potential to reach Rank 9, and they hoped that she might even become a Law Master someday.
However, Shiba had just destroyed that possibility.
