When Su Wuming found out about the rouge on Concubine Cao's face and that she had a habit of applying rouge at night, he suddenly thought of a way to kill people.

At this time, it is already summer, the weather is getting hotter and hotter day by day, and when you go to bed at night, you will inevitably sweat.

If sweat comes into contact with rouge and flows into the mouth, wouldn't it be another way of poisoning?

And if so, then the poison must be hidden in the rouge.

After thinking of this, Su Wuming immediately wiped off some of the rouge on Concubine Cao's face, and then conducted an inquest, and the final result was that the rouge was really poisonous.

Su Wuming's conjecture was right, the murderer Tong Guò poisoned Rouge, and then poisoned Concubine Cao.

Su Wuming glanced at Qing'er and asked, "What kind of rouge did Concubine Cao apply last night?" ”

Qing'er pointed to a box of rouge on the dresser: "It's that box." ”

It was a very delicate box of rouge, after opening it, you could smell a faint fragrance, Su Wuming checked it and found that the whole box of rouge was poisonous, Su Wuming took a closer look at the rouge in his hand, and found that this box of rouge was very different from the other rouge on the dresser, and the other rouge on the dresser were all uniformly purchased by the palace, but the box of rouge that was poisonous was not.

Su Wuming glanced at Qing'er and asked, "This box of rouge belongs to Concubine Cao?" ”

Qing'er nodded: "That's right, it's Niangniang's." ”

"But this is not uniformly procured by the palace?"

"This box of rouge was bought when the mother left the palace."

"Concubine Cao has been out of the palace?" Su Wuming was a little surprised, because according to his understanding, after a woman enters the palace and becomes a concubine, it is not easy to get out of the palace.

Qing'er nodded: "I went back to my parents' house a few days ago to save my relatives, and the rules in the palace are okay." ”

At this time, Cao Man chimed in on the side, saying that Concubine Cao did go home a few days ago.

If the box of rouge was bought by Concubine Cao outside the palace, then anything could happen, and it would be difficult to find who the murderer was.

"Concubine Cao went home to save her relatives, did you follow?" Su Wuming looked at Qing'er, if Qing'er followed, then he might be able to know who had touched this box of rouge, or know where Concubine Cao bought this box of rouge.

But what made Su Wuming feel disappointed was that Qing'er shook her head, Concubine Cao went home to save her relatives, and she didn't follow.

In this way, all hope is lost.

Emperor Li Yan left, Cao Man was very angry, and asked Su Wuming to solve the case, Su Wuming was a little helpless, so he had to continue to ask Qing'er: "Was Concubine Cao using this box of rouge for the first time last night?" ”

"Yes, after buying it, my mother has been reluctant to use it, and last night was the first time I used it."

"So after the rouge was bought, has anyone touched this box of rouge?"

"Except for Niangniang, no one has touched the box of rouge, Master Su, Niangniang's things, we who are slaves and maids, but we can't move."

The subordinates have what they should do, and they also know what they can do and what they can't do, which is the sorrow of the subordinates and the sorrow of this era.

Su Wuming frowned slightly, thinking to himself, if no one touched the rouge after Concubine Cao bought it back, then the only thing that could be poisoned in the rouge was outside the palace.

The category of rouge is very unique, there should not be many people who sell this kind of rouge in Chang'an City, and this kind of rouge looks very expensive, and there are not many people who can afford it, Su Wuming thought about it for a while, and then he had a plan, he wanted to send people to find a shop that sold this kind of rouge in Chang'an City, and then through guò investigation and screening, find out the shop that sold it to Concubine Cao, as long as you find that shop pù, it is much easier to know who did the tricks in rouge, of course, it is not excluded that after Concubine Cao bought rouge, during the period before entering the palace, Rouge was tampered with.

The time when Concubine Cao left the palace is very clear, so it is not very difficult to know that the shop sold the rouge to Concubine Cao through the correspondence in time.

With this strategy, Su Wuming began to send people to investigate.

The palace gradually restored its former tranquility and solemnity, Cao Man and others left the palace one after another, but when Cao Man left the palace, his face was very ugly, and after returning to the palace, he immediately said to Cao Chong: "You hurry up and send a letter to the prince, just say that we are ready to respond at any time in the city, and the prince should also be ready." ”

Cao Chong nodded, but he hesitated a little: "Daddy has made up his mind?" ”

Cao Man nodded: "Chai Qi was arrested, our affairs will be confided in him sooner or later, I know that old thing too well, in order to survive, he can do anything, and now your sister has been murdered again, our only backer is gone, and all we can do now is to conspire with the prince." ”

After hearing this, Cao Chong showed a hint of longing on his face, and said, "Father, don't worry, leave this matter to the child." ”

Concubine Cao's body was pretended to be buried, and now the weather is getting hotter and hotter, according to the emperor's will, the sooner the burying the better, but Concubine Cao is the emperor's woman after all, so there are still due rituals, and these ceremonies are done, I am afraid that it will take several days.

After Su Wuming left the palace, he felt that the murderer must be the one who skinned the wild cat, but until now, he didn't understand who that person would be, why Concubine Cao had to die, and if the murderer was really that person, how could Concubine Cao poison the rouge sold from outside, according to Qing'er's description, after Concubine Cao bought rouge, no one had touched the box of rouge.

Could it be that the rouge was not bought by Concubine Cao from outside the palace?

Su Wuming thought about it carefully, and felt that it was unlikely, because there was no rouge like that in the palace, and he could only wait for the results of the investigation by the officials.

A fast horse rode out of Chang'an City, and soon disappeared into the emerald green outside the city, and at this time, another person hurried to Su Mansion.

The man entered the Su Mansion, and after seeing Su Wuming, he told Su Wuming what he had discovered, and after Su Wuming listened, a smile appeared on the corner of his mouth: "It seems that they finally can't wait." ”

The person who came nodded and nodded: "Lord Su's guess is not wrong at all, but what should we do now, are we trying to find a way to let the emperor know?" ”

"You don't have to worry about the next thing, I only have to arrange, as for letting the emperor know, I think the emperor already knows."

Emperor Li Yan's inner secret agents are much more clever than Hu Fei's investigation methods, and what Hu Fei and they can investigate, presumably those inner secret agents will also be able to investigate.

As long as Emperor Li Yan knows about this matter, then he Su Wuming only needs to investigate the murder in the palace clearly, although Cao Man wants to rebel, but the murder in the palace has happened, and the murderer must be punished.

The night is getting deeper, the palace is very quiet, Concubine Cao's body is parked in her bedroom, so let the palace maid keep the spirit for another night, and tomorrow I will find the road to do a ritual, and I can be buried in the afternoon, because the weather is getting hotter and hotter, Li Yan finally ordered to make the rules simpler.

Concubine Cao was lying on the bed, her appearance was as serene as when she was found, a palace maid stood next to the corpse to give the final cleaning of the corpse, she slowly took off Concubine Cao's clothes, and then picked up a towel to start wiping Concubine Cao's body, but at this time, she found that Concubine Cao's body had changed significantly, and this change was not there earlier today.

The palace maid hurriedly met the emperor and informed the emperor of her discovery, after the emperor Li Yan listened, his brows suddenly condensed slightly, and a wave of anger was almost out of control, but he was the emperor after all, he actually endured his anger, and told the palace maid that this matter could not be said to anyone, if anyone else knew about it, he wanted the palace maid's life.

The palace maid felt very scared, but she couldn't understand the reaction of the emperor Li Yan, and in the end, what she could do was to keep this matter silent as Li Yan said.

However, after the palace maid left, Li Yan immediately sent someone to call Su Wuming, no one else knew about this matter, but Su Wuming couldn't know it, because at this time, Li Yan had secretly sworn in his heart that he would let the murderer be cut by a thousand knives, and in addition, he would kill another person.

Su Wuming entered the palace overnight, he looked very tired, and when he saw the emperor Li Yan, he had to cheer up again.

It's just that after Su Wuming listened to Li Yan's narration, Su Wuming couldn't help but be surprised, and blurted out and asked, "What, Concubine Cao is pregnant?" ”

Earlier today, Su Wuming had checked Concubine Cao's body, but he was not a doctor and couldn't take the pulse, so he couldn't see that Concubine Cao was very pregnant, but listening to the meaning of Li Yan's words, when Concubine Cao's belly was wiped by the palace maid tonight, it seemed to bulge slightly, but this bulge was not there this morning.

Could it be that the fetus in Concubine Cao's womb slowly expanded after she died?

Su Wuming didn't know anything about medical skills, so he didn't know what was going on, but to verify whether Concubine Cao was pregnant, Su Wuming still had a way, and that was to dissect the corpse.

It's just that before Su Wuming dissected the body, he had to understand one thing, that is, Li Yan hesitated for a long time before he said it, in the past few months, Emperor Li Yan has never been fortunate to Concubine Cao, so whose child is the child in her belly?

Emperor Li Yan was very angry about this, even if he was not ready to visit Concubine Cao, but Concubine Cao was his concubine after all, since she was his concubine, how could she allow other men to get involved, and that man was so bold that even the emperor's women dared to play.

In the face of Li Yan's anger, Su Wuming can understand, whether it is that man, as long as he is given a green hat by others, he will definitely be angry.

Su Wuming endured Li Yan's anger, and at this time, he suddenly found a turn for the better.
