Xin Zimen's revelations left Xiu in deep thought. He told her everything she asked without hiding anything. For some reason, he couldn't stop himself from telling the truth. The earnest look in her eyes was enough for him to reveal everything he knew at this point.
But even he knew that what he was aware of wasn't enough at all. However, if it could help her, then what was the point of keeping it to himself. It wasn't like he was gonna hide it forever. No matter what, somethings couldn't stay hidden for good.
"Now, would you like to tell me how you connected everything to me? Why did you assume that I'm related to your father?" he might not have been surprised with other things but he was certainly curious to know how she knew that he was related to her father? If she had no memories, then how did she come to that conclusion?
