To best understand a person's situation, the most direct way was to make conversation. Although it seems like a normal conversation, as long as the other party could answer your question, you would be able to get the information you want even if the other party said a few ambiguous words.
Without a doubt, Big Whale was a good conversationalist. He first praised Ye Jian and gave her a friendly impression. Then, he laughed and said that the reason why she was so good was that she had similar training in the past. Otherwise, why would she deal with these clams?
