This is why Du Chuke was so nervous after hearing that the files had been burned.

After all, if such an important file is burned, it means that the past experience and lessons are gone, and everything has to start from scratch.

How much waste and loss will this cause?

With Li Shimin's temper, let alone scolding him, he could be demoted and slapped with a ban.

Qin Wenyuan looked at the content and touched the paper carefully.

The paper is yellow and dull, the pages are dry and slightly brittle, and everything contains traces of time.

This is consistent with the time of the dossier and is the true standard of how the paper should look.

Qin Wenyuan put the files back and said, "How many files are there in total? Why did you choose these files to take away?"

When everyone heard this, they all looked at Han Xun.

Han Xun said: "There are 275 volumes in total. It took me more than a year to take them out, then I excerpted them myself, and then put them back."

"The reason why I chose these files is because when I was following Zhang Qin, I found that Zhang Qin would stop in front of the bookshelf of these files almost every time."

"Zhang Qin is very cautious. He does not come directly to the bookshelves of these volumes every time. Instead, he often goes to other bookshelves to stand and read for a while, and then finally comes to these bookshelves."

"Then, he will read these files very carefully, even reading them over and over again."

"I don't know what he is looking at, but I know that taking away all the files on this bookshelf will definitely not go wrong."

"So, I took them all away."

Qin Wenyuan narrowed his eyes and said, "Your process lasted for more than a year, and Zhang Qin never found out?"

Han Xun said: "I must be very cautious. I start from the file in the corner. I will only replace it every time if there is something that can be replaced."

……………………

"And the paper I used and the writing position were as identical as possible to the original dossier. In addition, Zhang Qin was very familiar with the content. He hardly looked at the content carefully, so he didn't notice it."

Qin Wenyuan's eyes flashed and he asked: "You said, Zhang Qin didn't check the content carefully?"

Han Xun nodded: "He flipped through the book very quickly. He would never be able to read the entire content clearly if he flipped through the book at such a fast speed."

…………

Qin Wenyuan looked at these files and thought quickly.

Zhang Qin and the fake Han Qian have been searching for the secrets in the files for ten years!

Ten years and more than two hundred files were enough for them to memorize their contents.

However, they still haven't found it.

Even later, I stopped reading the content...

Does this mean that the secret they are looking for has nothing to do with the contents of the dossier?

Or are there other reasons?

Qin Wenyuan recalled what Mrs. Han said to him.

Before Han Qian was replaced, he was repairing some building and said he had discovered some terrible secret.

Then it was replaced!

So what kind of building did Han Qian repair?

Since it is a renovated building, there must be records of the previous construction of this building.

So, is this dossier among the dossiers in front of you?

Which one will it be?

Qin Wenyuan looked at Du Chuke and said, "Master Du, there is something. I wonder if Master Du knows about it."

Du Chuke hurriedly said: "Master Qin, please speak."

Qin Wenyuan said: "I heard that Han Qian was responsible for the repair work of a building before his temperament changed drastically ten years ago. The reason why he was later replaced by a traitor is most likely related to the repair of this building."

"So, I would like to know if Mr. Du knows... what kind of building Han Qian renovated ten years ago."

"this……"

Du Chuke frowned slightly and said: "To be honest with Mr. Qin, I did not come to work in the Ministry of Industry ten years ago. I was transferred to the Ministry of Industry five years ago."

"So I really don't know much about what happened ten years ago."

"But I can help Mr. Qin ask other veterans. They may know."

When Qin Wenyuan heard this, he was about to nod.

Suddenly I heard a voice: "I know what building Han Qian renovated back then."

As soon as these words came out, Qin Wenyuan looked suddenly.

The person speaking was none other than Han Xun.

"you know?"

Du Chuke asked hurriedly.

Han Xun nodded.

"I have been in the Ministry of Industry long enough and I know a lot about many things."

"And when Han Qian received the repair task, the task was originally supposed to be handed over to me, but because I had other tasks, I finally handed it over to Han Qian."

"Later, Han Qian once asked me for some advice. At that time, Han Qian was very humble and polite. I had a good impression of him. But soon after, Han Qian seemed to have turned his back on him and completely forgot about my feelings for him.

It's the same as helping... This incident made me feel very uncomfortable, and I remember it deeply."

Qin Wenyuan's eyes lit up slightly when he heard Han Xun's words.

This is really a search for him through hundreds of thousands of people!

He looked at Han Xun and said, "What building are you repairing?"

Han Xun didn't hesitate and said directly: "The Temple of Heaven in the Imperial Palace."

"Temple of Heaven?"

Information about the Temple of Heaven quickly appeared in Qin Wenyuan's brain.

The Temple of Heaven should be called an altar.

It is the place where emperors worship heaven in the palace.

But this altar is different from the altars outside.

For major events in the past, such as the annual spring plowing sacrifices, such as sacrifices at important seasons, the emperors would go to the altar outside Chang'an City to perform such sacrifices.

Because these altars allow ordinary people to watch from a distance.

The purpose was naturally to let the people know that their emperor was very concerned about their affairs.

However, in addition to big things, there are also some small things that also require sacrifices.

For example, the emperor had a nightmare.

As the emperor, the emperor would think that their dreams were sometimes unusual. Therefore, after repeated nightmares, he would ask someone from the Ministry of Rites to have them calculated. After the Ministry of Rites completed the calculations, the emperor would go to the Temple of Heaven in the palace.

, perform sacrifices.

Offer sacrifices to ancestors and gods.

And these things are not good for the people to watch. After all, in the eyes of the people, this is just a nightmare. It is not worth such a sacrifice.

But for the emperor, they always feel that there are always unscrupulous people who want to harm me, so a dream is worthy of their attention.

The Temple of Heaven mentioned by Han Xun is such an altar.

Located in the southeast corner of the palace.

It has its own courtyard.

The door is usually locked.

Only the emperor will turn it on when he needs it!

Sometimes, it will be turned on frequently.

But sometimes, it doesn’t happen even once a year.

Qin Wenyuan knew about the altar because when Li Shimin married him and Changle, after calculating the good days in the Ministry of Rites, he went there to offer sacrifices to the heavens and inform the gods and royal ancestors.

Therefore, he really knows some things about the Temple of Heaven, but he has never entered it.

After all, outsiders are not allowed to approach the royal sacrifice.

And he and Chang Le have not yet officially married, so they are not considered a family yet.

Qin Wenyuan looked at Du Chuke and said, "Master Du, do you have the files on the Temple of Heaven?"

"have!"

Du Chuke knew what was at stake.
