There is no problem with osmanthus cake, this is not a fatal factor, what is the fatal factor? What is the real cause of Concubine Hui's death? Wang Laohu thought of looking at Concubine Hui's corpse, which might tell more.

"Lord Cao, now it seems that there is no problem with this osmanthus cake, we have reached a stalemate, so what is the real cause of death of Concubine Hui, we have to start from the other side."

"What do you want to start with?" Master Cao asked.

"Look at Concubine Hui's body."

"No, this must not be, this Concubine Hui is a daughter, how can we ordinary people see it."

"Master Cao, now that we think the biggest suspicious clue has been broken, should we just give up. The emperor ordered us to decide the case, I will not give up, and you should not give up either. So I'm going to look at the corpse, maybe we can get more clues from the corpse. ”

"If you do this, the emperor will not agree."

"So I want to ask Lord Cao to ask the emperor for instructions, Wang Laohu asked to see the corpse of Concubine Hui, Wang Laohu did not mean to offend Concubine Hui, I just want to complete the task given to us by the emperor as soon as possible, just to find out the real culprit as soon as possible."

"Okay, Wang Laohu, I'll listen to you this time, go and ask the emperor for you, whether the emperor will agree, I don't dare to guarantee."

"Okay, thank you, Lord Cao."

After a long time, Lord Cao returned to Wang Laohu's side dejectedly: "Wang Laohu, this official has asked the emperor, but the emperor does not agree. ”

"The emperor doesn't agree, I'll go and tell the emperor myself." Wang Laohu said.

"Wang Laohu, who do you think you are? The emperor asked you to investigate the case of Concubine Hui's violent death, you really think you are so great, you are just a grass people. ”

"Master Cao, we have no clues now, and now if we start with the corpse of Concubine Hui, we may find new clues."

"What you said is just maybe, if you can't find a clue, you are doing this is a great disrespect to Concubine Hui, and it is also a great disrespect to the emperor today!"

"Lord Cao, did we just give up? The emperor ordered us to investigate the real culprit, which is a trust in the two of us, and also a consideration for the two of us, we give up halfway, do you think this is really good? ”

"The emperor didn't let us give up, but let us start from other directions and find clues again."

"Isn't that child's play? Are we wandering around without a purpose, asking anyone to ask? One has no time; 2. Waste of time; Three people laughed at. ”

"Wang Laohu, the emperor also asked me to bring you a sentence, this sentence is written in this letter, the emperor said, this letter is top secret, no one can read it, only you are allowed to read it alone." After Lord Cao finished speaking, he took out a letter from his bosom and handed it to Wang Laohu.

Wang Laohu came to a secluded place, opened the envelope, and took out the letter. Strangely, there was no writing on the letter, but a picture was drawn, what kind of mystery the emperor played, the content of the painting was "A man is changing clothes, his left hand is up, one finger is extended, the sleeve has been put in, and the right hand is down, three fingers are open, and the cuff has not yet been worn." Another man was looking. ”

What does this painting mean, and why did the emperor ask Lord Cao to bring this painting? Wang Laohu put the painting back into the envelope.

The night had already darkened, and Wang Laohu returned to the residence temporarily arranged by the emperor, which was a temporary accommodation arranged for Wang Laohu and others in order to solve the case conveniently, safely and confidentially.

Wang Laohu paced back and forth in his residence, thinking about the painting that the emperor had left him. The emperor will not give Wang Laohu such a painting out of thin air, there must be some mystery hidden in this painting, what kind of message does the emperor want to convey to Wang Laohu?

The man is changing his clothes, why are he changing his clothes, is the clothes too old, or are they too torn? Wang Laohu carefully looked at this person's clothes, which were not damaged. What does it mean to have a finger stretched out towards the sky? The sky is the emperor, one finger to the sky, is it for me to go to see the emperor alone? So what does it mean that the three fingers at the bottom are open? Do you tell us that there are still three people or three clues to be verified?

What does this dumb riddle that the emperor plays?

The night was darker, and the husband outside had already knocked on the watch, "Knock! - Knock! Boom! - Knock! Boom! - Knock! Wang Laohu still didn't feel sleepy, and this mysterious painting has always surrounded Wang Laohu's mind. This particular period does require special means, but what important information is hidden in this letter? What is the emperor trying to tell me? Sometimes the more you try to figure it out, the harder it gets.

The night has deepened again, and the husband has already knocked on the second watch, "Knock! Boom! Boom! Boom! Boom! Boom! Wang Laohu is still thinking about the content of this letter. Wang Laohu took out the envelope and took out the letter again, there are two people in the picture, the one in front should be the protagonist, he is changing clothes, one hand has been put into the sleeve, the other hand has not been put into the sleeve, one hand is stretched out with one finger, and the other hand is open with three fingers.

Wang Laohu looked at the hand that had been put into the sleeve, one finger, and the hand that had not yet been put into the sleeve was open with three fingers. What does one finger, three fingers, mean?

Wang Laohu walked out of the room, it was very cold outside and covered with snow, Wang Laohu had never felt so helpless, a dumb riddle of the emperor, what direction can be cracked it, there must be a direction to crack it, where is this idea.

Morse Code? It is a signal code that is on and off at one time, and there must be no one in this era. What does the emperor want to pass on? Wang Laohu reluctantly entered the house again, unable to think of it for a while, let him be quiet, and sometimes he can find new ideas.

That's it tonight, no matter how you think about it, there is no idea, and if you have an idea, you don't have a good idea. Wang Laohu thought that since he couldn't think of it, he still went to sleep, so he undressed himself and prepared to sleep, and suddenly he thought of the painting that the emperor gave him, the man was also undressing, I had been thinking about dressing just now, isn't this dressing, but undressing? When you undress and go to bed, it's night, what time is the night? A finger? Three fingers?

Strip or dress. It can be said that it is a change, is it a change? Midnight? One finger, the sleeve has been threaded in. With three fingers open, the cuffs have not yet been threaded.

The letter means "One more tonight." Or "Three watches tonight?" "If it is a change, this change time has passed, and I have failed the emperor. If it is a three-more entry, then where should it be entered?

The direction of this finger, the left hand up, stretches out a finger. The right hand is downward, with three fingers open. Wang Laohu suddenly realized that the emperor was using this letter to tell him that tonight the third watch (people are changing clothes, three fingers), and one person (one finger) enters the palace from the north gate (left hand up, up north and down south). A man next to him was looking, meaning that someone would come to answer him.

Wang Laohu cracked the letter, and his heart was excited, and he protruded his clothes again, waiting for the arrival of the third watch in the middle of the night.

The night has deepened again, and the husband has already knocked on the third watch, "Knock! - Knock! Boom! When the time came, Wang Laohu put on a thick coat and headed towards the north gate of the palace.

Just as Wang Laohu cracked, there was a person waiting at the north gate.

The man didn't speak, led Wang Laohu to a place, and said, "The emperor only gives you a pillar of incense time, and after a pillar of incense time, there will be palace guards passing by here." ”

A pillar of incense time, this time is enough, Wang Laohu came to Concubine Hui's corpse, Concubine Hui's face was not peaceful, thinking that she must be very painful before she died. Four days have passed since the accident, and Concubine Hui's lips have turned black. Her lower abdomen bulged slightly, which was supposed to be the fetus in her womb. Thinking that the fetus was not born and died, Wang Laohu felt sour. He put on a pair of simple gloves, touched Concubine Hui's lower abdomen, and then looked at her face and all over her body. Concubine Hui did have a mark on her face, this mark was on the left side of her face, like a mark from a cat's claw, and there was no wound anywhere else. Although the lower body has been wiped, there are still some blood stains.

Wang Laohu was afraid that there was something missing, so he looked at it carefully from top to bottom, and the time was almost up, Wang Laohu withdrew, and the person who answered led Wang Laohu out of the north gate safely.
