Though Sato held back a bit against the Kobold King, it didn't mean that he wanted to drag out the battle. Sato knew that the longer the battle went n, the more impatient the two teams behind would get. But since he didn't have any idea how to handle them yet, he had to drag out the battle for as long as possible while he thought of one. While he did so, he sneakily sent a message to Seiichi and Xue Yan. Sato guessed that they still weren't so far from his position as Fudo and the others, plus, Xue Yan was needed to complete the mission.
'Hmm? They can't wait anymore.'
Since both he and the Kobold King weren't doing their best, Sato was able to partition a portion of his senses to the 'fishermen'[1]. He noticed that they had changed their strategy and begun to surround the two of them. This was most likely because they got impatient an wanted to end the battle quickly to prevent any risks from occurring.
'Guess I'll have to use it then.'
