Returning from the library and walking on the way home, the doubts in Yang Xuan's heart did not decrease at all.

"It seems that we will have to sort out what is happening so far when we go back." Yang Xuan thought to himself.

However, some things are easy to say, but when you actually do them, they are not so easy. Yang Xuan had a deep understanding of this at this time.

Yang Xuan thought about it for a while and decided to use the enumeration method to sort out these clues.

1 For unknown purposes, a man sent him a package containing an ancient map, torn from a book.

2 A very good woman took a historical atlas.

3 The next day, someone took all the historical atlases.

4 My father's friend disguised himself as a librarian and claimed to be someone who didn't exist.

......

At this time, Yang Xuan wanted to cry without tears in the face of these trivial and messy clues.

"These people don't have any clues left for me, huh?" Yang Xuan felt a burst of grief and indignation in his heart.

"When is it going to be a head?" At this time, Yang Xuan deeply experienced the hardships of the police.

"Now that I think about it, that administrator probably deliberately showed his flaws to test me." Yang Xuan sighed, "But what is there for me to be tempted?" "You know, from childhood to adulthood, except for a slightly better grade, everything about Yang Xuan is unknown.

"The revolution has not yet succeeded, and comrades still need to work hard." Yang Xuan cheered himself up.

But Yang Xuan knew that his opponents were a group of people who were very cautious, and it was really difficult to catch them.

"Perhaps, I need a professional to help me."

Yang Xuan thought about it and felt that his idea was not bad; But Yang Xuan thought about it, he had so few friends and a relatively weak relationship, who could help him.

At this time, Yang Xuan heard someone knocking at the door.

Yang Xuan looked at the time and found that it was already midnight, and it seemed that he had been busy for a long time unconsciously.

"Strange, who will it be at this time?" Yang Xuan thought to himself.

But when Yang Xuan opened the door, he found that there was no one outside the door, and Yang Xuan felt a chill in his heart.

But at this time, Yang Xuan saw another package on the ground, Yang Xuan took a look, and found that this package was the same as the previous one, and there was no sender.

But unlike the previous one, this time the package is much larger than the previous one, and I don't know what it contains.

"Why is there another package," Yang Xuan was taken aback, knowing that he hadn't figured out the contents of the first package until now, and now there was another one.

"Who sent this to me?" Yang Xuan thought to himself, "What could such a big package contain?" ”

"Forget it, let's move home first." As he spoke, Yang Xuan moved his hands.

But what Yang Xuan didn't expect was that this package was much heavier than he expected, and Yang Xuan wasted a lot of energy before dragging it into the door.
