Shiba's attacks became more violent after receiving the message from Ravier.
He hadn't been too eager to finish the battle before because the pressure was helping him to improve really fast, so he didn't care that his opponent was like a cockroach, but once his master's reincarnation was at stake, he didn't dare to lose more time.
At the same time, Shiba's opponent was also reaching his limit. He only had a single treasure left, and it was of the attacking type.
He had lived a long life, and he collected as many treasures as possible. He was far older than Lina and Liye together, so he had a lot of time to collect them despite his low strength.
However, the number of treasures was still finite, so after battling for so long against Shiba, they reached the point of only one more remaining before exhaustion.
