"Anyway, I thought I must have been unconscious for a long time." Xue Wuhu continued, "That's why I was in Prince Xu's estate when I opened my eyes. But that darn girl told me that it's been less than a day since I left camp. I thought I was still in the military camp. I thought she was lying to me, so I scolded her. I thought I was still in Da Ling. At that time, that darn girl thought that there was something wrong with my brain. She probably still wouldn't believe me if I said I was in Da Ling's camp the night before. But I am certain that I was. It was really amazing. How could that mysterious person be so magical? He sent me to Beicheng Imperial City so quickly."
It was precisely because they knew that Wufu was sure of this that they told Wufu about this and did not hide it from him.
Otherwise, even if they didn't say anything, Wufu would tell them his findings and call it magic.
