Yang Xuan knew that his parents had passed away, so the other party was not using his parents to blackmail him, but for another reason. Therefore, Yang Xuan had to find the reason and purpose for the other party to do this.

Yang Xuan picked up the map, looked at it carefully, and found a strange place name in the corner of the map: Tanzhou. ''Tanzhou, a familiar place name'' Yang Xuan thought for a long time before remembering that this is the ancient name of Changsha.

Subsequently, Yang Xuan took out his mobile phone and searched Tanzhou on the Internet, and found that Tanzhou was the place name from Sui to Ming, including Changsha, Xiangtan, Zhuzhou, Yueyangnan, Yiyang, Loudi and other places. ''In other words, this is a historical map''' Yang Xuan thought to himself, ''If it's a historical map, I remember that the woman was holding a historical atlas''

''It seems that the woman has nothing to do with it.'' ’’

''The point is, I don't know what kind of map this is?'' Yang Xuan thought to himself, "It looks like I still have to go to the library."

But when Yang Xuan arrived at the library, he found that the row of bookshelves was empty. ''How is this possible?'' Yang Xuan had 10,000 grass and mud horses roaring past in his heart, "Who is so lacking in virtue??? Yang Xuan felt a burst of grief and indignation in his heart, and the clue was cut off in front of him.

But Yang Xuan was not willing to lose the clue like this. At this time, Yang Xuan suddenly remembered that all books had to be registered with the administrator.

So, Yang Xuan quickly ran to the administrator, for fear that something would happen.

Obviously, it was Yang Xuan who was too worried, and when Yang Xuan arrived there, Uncle Administrator was still drinking tea there.

''Uncle, what are you ......''

"Don't mention it, I'm alone, I don't have an internet, I'm bored to death." ’’

''Uncle, how long have you been here?'' ’’

''It's been almost ten years, and I know every single book here.''

"Uncle, do you know a historical atlas? ’’

'''Historical Atlas?'' ’’

''All five books were borrowed. The administrator replied lightly. Do you remember what kind of people they were?'' Yang Xuan asked anxiously.

''I think about it, it's a woman, and two strong men. ''Administrator said. ''Two strong men? Yang Xuan was surprised, and felt that something was wrong, the other party turned out to be two strong men.

''Why a strong man''

''They're so muscular,'' said the caretaker as he took a sip of his tea, ''Seriously, I've never seen anyone that muscular, except on TV.'' ’’

''What about the other two?'' ’’

The two strong men each borrowed two copies. The administrator replied.

''Borrowed two?'' Yang Xuan thought it was strange, generally speaking, it was enough to borrow two books at most.

''yes, they also borrowed two for a friend. ’’

Yang Xuan sighed, it seemed that this time it was destined to be in vain. ''Thanks, uncle. You''re welcome, lad. With that, Yang Xuan prepared to get up and leave.

However, looking at the administrator drinking tea there, Yang Xuan felt more and more that something was wrong in his heart, thinking of what the administrator had just said, Yang Xuan chuckled in his heart, and said in his heart: No, there is something wrong with this person.

''What's wrong, is there anything else?'' Lad. '' The administrator asked.

''Uncle, it's not right to lie. Yang Xuan leaned towards the door as he spoke, for fear that something would happen.

''Oh? ''The administrator seemed surprised.

''You're not an administrator, where is the real administrator?'' ’’

The administrator finally stopped drinking tea, slowly stood up and asked, "Who are you?" ’’
