''I'm Yang Xuan. Yang Xuan replied.

''Yang Tieba's son? The man seemed a little surprised.

''Ah, you, know my dad?'' Yang Xuanqiang couldn't hold back the surprise in his heart.

''We've known each other for a long time, what's wrong?'' The man replied with a smile.

''Anyway, how did you find out that something was wrong with me?'' The man asked again.

''What a big library, how can you be alone?'' This doesn't make sense. Yang Xuan said, "Moreover, even if you are the only one, you should have a computer, and the current library management uses computers, and it is impossible to have no network." ’’

''Hehe, a little clever; Since you are the son of Yang Tieba, then I will not embarrass you; Oh yes, and remember to close the door when you go out. With that, he sat down and drank his tea, still with no expression on his face.

Yang Xuan knew in his heart that the other party probably didn't intend to continue to pay attention to him, so he had to leave.

When he walked to the door, out of curiosity, Yang Xuan turned around and asked, "Then who are you?" ’’

''I'm a non-existent person. The man smiled.

''Someone who doesn't exist, know my dad, who the hell is he?'' Yang Xuan kept thinking about this question on the way.

''Looks like I'm going to have to go to the library tomorrow.'' Yang Xuan smiled bitterly.

In the library

''What, you actually rested yesterday?'' Yang Xuan's eyes widened.

''What's wrong?'' Administrators are also meant to take breaks. The administrator asked, ''What's going on?'' ’’

"Yesterday, I ...... here" In addition to the matter after revealing the identity of that person, Yang Xuan told the administrator everything that happened here.

''No way,'' said one of the administrators, ''I remember locking the door before we left.''' ’’

''It's just a door, what's the big deal.'' Yang Xuan thought to himself.

''Is there anything missing here?''

"Absolutely not," said another administrator, "we've checked it before we go to work." ’’

''What's changed here?'' Yang Xuan still didn't give up.

''Change, not much. ''The Administrator said

''yes, if there is, we'll find out.'' The other administrator said, "Let's go, boy, if there's anything you need to come back." ’’

''Thank you then, goodbye.'' After speaking, Yang Xuan left here.

But what Yang Xuan didn't know was that after he left, the two of them took off their disguises and turned into a capable woman and a burly man.

''Three twilight four, four twilight three?'' The woman smiled at the man next to her.

''yes, that's funny little guy, otherwise I wouldn't have sent it to him.'' The man replied, "What would he do if he knew we were really employees here?" ’’

The expression on his face must be wonderful! ’’

''yes, hahaha!' ’’

''Those two bosses, can you ......?'' asked a few people behind him.

''Of course, we'll leave right away, and we won't delay your work.'' The two laughed and left.
