Early the next morning, Di Qing went to the scene of the sword meeting, and everyone came to cheer for him.

Not surprisingly, Di Qing achieved good results, and finally won the second place in the Sword Debate.

"Xue'er, I'm going back to Shudi, you can go home and see when you're free, everyone misses you very much!"

After Di Qing finished speaking, she took Di Xue's hand and was very reluctant.

"Sister, don't worry, but be careful when you go back, remember to pass the book to me."

After the Di sisters separated, everyone in Yuanjing also embarked on a journey back to Beijing.

On the way, Di Xue did not take the carriage but rode in front, recalling Yan Min's words.

"Master Di, my father's innocence depends on you!"

"Amin, don't worry, I will definitely find out the truth of the case, cherish!"

Di Xue saw the expectation and uneasiness in Yan Min's eyes, maybe she felt that she had handed over this matter too hastily, or maybe she really saw hope......

Everyone traveled all the way south and finally rushed back to Yuanjing before dark.

"Ladies and gentlemen, there is another request below, Amin's matter is still unclear, I hope you don't disclose this matter for the time being!"

Di Xue knew that it was a bit rude to say this, but this case must be carried out secretly, and once it is investigated, the people who survived back then may suffer unjustified disasters.

And this involves the old case of the first emperor, whether it is overturned or not, it will be controversial, so Di Xue can only be cautious.

"Don't worry, Master Di, we will keep our mouths shut, and you can call me at any time if you need anything." Zhou Huaiqiang said in front of Chu Ran.

Di Xue arched her hand to express her gratitude, and then everyone separated, and Di Xue and Chu Ran rode back home.

"Don't worry, the truth will definitely be found out." Chu Ran whispered.

Di Xue nodded lightly: "Tomorrow the emperor summons, you and I still need to think of an explanation." ”

On the second day, Di Xue and Chu Ran were stopped by Qian Zhangyin, so the two went to Wuying Palace.

Emperor Chu Yun was dressed in casual clothes at this time, and the brocade robe with gold edges on a white background was still indescribably luxurious.

Di Xue was relieved when she saw this, it seems that the emperor understands that the theft case cannot be put in the court for the time being.

"What interesting news is there when Di Aiqing and Chu Ran came back from Dingbei, today you don't care about the monarchs and ministers, just gossip!"

After Chu Yun finished speaking, he leaned back, and Qian Zhangyin put the pillow behind him very eye-catchingly.

Then Chu Yun really relaxed like a peer gathering, quietly waiting for Di Xue's next words.

Di Xue stepped forward and saluted: "The minister has a strange news about Your Majesty!" ”

Chu Yun waved her hand to signal her to continue, so Di Xue said:

"The minister and the prince traveled to the north, but they heard a rumor. The local monsters are on the border, and there is a raccoon cat that is a good man and makes trouble at night. ”

After hearing this, Chu Yun slowly turned the wrench in his hand and said, "There is such a thing in my Dongwu land? ”

Di Xue nodded:

"Back to Your Majesty, I and the prince naturally don't believe it, but the people of Dingbei have a hard time, saying that every night they will hear cats meowing on the outskirts of the city, and there will be crying!"

"So Master Di and I went to the outskirts of the city at night!" Chu Ran followed Di Xue's words.

"Oh? What is the result, can you see the cat demon? Chu Yun asked with a smile.

Di Xue shook her head: "Shizi and I did see a very large wild cat on the outskirts of Beijing, and it ran quickly, so we chased the wild cat to the front of an abandoned house, but heard a knock on the door from inside. ”

Chu Yun looked at Di Xue and smiled even more: "Di Aiqing can go in?" ”

Di Xue nodded: "I entered the house with His Royal Highness the Prince of the World, but we were separated by the fog!" And when I went to the lake, I saw a river mussel shining, and when I picked it up, I fell asleep, and in my dream I dreamed of a fairy who told me a story, and I was very surprised when I heard it, and when I wanted to ask it, I woke up! ”

"When I came out with Master Di, I saw the word Yan Mansion written on the door of the mansion, which turned out to be the mansion mentioned by His Majesty, and we went by mistake!" Chu Ran received.

"Do you remember the story of the gods, Master Di?" Chu Yun asked.

"Back to Your Majesty, the minister remembers, for some reason, that story is engraved in my mind just after reading it once!"

Hearing Di Xue say this, Chu Yun was not ambiguous, and ordered someone to bring a pen and paper for Di Xue to write down, so he could read it slowly.

Di Xue took the pen and sorted out the Yan family's daughter, Yan Fu and Chen Qing's letter together, and wrote it.

By the time I finished writing, it was close to noon.

Chu Yun nodded again and again after reading it:

"This story is also wonderful, Master Di has a copy of the criminal department book from many years ago, I can't figure it out, you can take it back, sort it out and hand it over to Qian Zhangji!"

Di Xue nodded in response, opened the booklet and found that it was the information of the Criminal Department twenty years ago, and she knew in her heart that the emperor asked her to check it.

"Do you really remember it?" Out of the Wuying Palace, Chu Ran asked in a low voice.

Di Xue shook her head, then leaned her face closer to the black blue faintly shining under her eyes and said:

"Even if you really remember it, it's hard to write down so much trivial information at once! Being able to write most of the stories in the main hall today is the result of my hard work last night! ”

"You're bothered."

After Chu Ran finished speaking, Di Xue sighed lightly: "If you don't say so, if you take out the real love letter, I'm afraid it will implicate many people!" ”

After returning to Dali Temple, Di Xue looked at the love letters sorted out, and kept repeating the question of why the murderer did this.

After a while, she stood up and looked out the window, and by this time the weather was already slightly cooler, and the leaves of some trees had fallen, leaving a bare trunk.

More than 20 years have passed since this case, and if we blindly pursue the goal, I am afraid that we will take many detours.

It is better to study the methods used by the murderer to make thousands of files disappear in less than half a stick of incense.

Perhaps, when the modus operandi is thoroughly studied, the perpetrator will naturally be revealed!

After thinking about it, Di Xue suddenly felt enlightened, and hurriedly took the love letter and studied it carefully.

Twenty years ago, the management of the house where the criminal department kept the files was extremely strict, and all the windows around it were sealed and there was no way to pry them open.

The only exit is the main entrance of the house.

The main entrance was a single piece of wood, and the iron was so hard that it could not be broken open.

So if you want to enter the house, you can only work on the lock.

The lock is specially made by the palace, there are three keys in total, one is Yan Tingzhong, the secretary of the criminal department, and one is each a waiter on the left and right.

If you want to open the file room, you must get the confirmation of three people, and the rest of the people cannot keep the key.

And there are no suspicious traces on the floor and roof of the room!

Could it be that there is something wrong with the door lock?

Di Xue recalled that seven days before the crime, a Shen Lang of the Criminal Department found that the door lock had traces of corrosion.

So I had to replace the door lock with an ordinary door lock first, and the next day the palace sent the lock to replace it.

And the punishment department deliberately added guards on that day when they were replaced with ordinary locks, and there was no abnormality.

And since then, people have entered the house every day to exchange for files, and there is nothing unusual.

What went wrong?

Di Xue opened the information of the Criminal Department given by the emperor, looked at Lang Zhong of the Thirteen Qing Officials Division of the Criminal Department, and suddenly a name jumped into her eyes, could it be that the emperor's purpose is here?
