Arthur was least interested in biology, so he didn't know if being sweaty ran through genes. However, when the baron's son tried to answer his question about visitors, he turned into a mini fountain.
"We receive many visitors, mostly young nobles wishing to hone their skills and face hardships," Randolph tried to wipe away his sweat. "As for any-any others, I don't remember. After all, they were many, haha."
Arthur squinted his eyes at the man, who was clearly of a guilty conscience. However, he kept stuttering and sweating meant that he at least knew that something was off. The rest could easily be uncovered using his submission art.
"I understand," Arthur wanted to save his art for last after he gathered enough clues himself. "Then, we should visit the lake first. What do you think?"
