"Princess, is this a suspicion of slaves?" Mama Li had a little self-deprecation under her voice.

"I want to know, where did the burn on Mama's arm come from?" Su Liuyu's eyes glanced towards Mama Li's right arm.

Mama Li looked stunned.

As a slave or a maid, whether there is an injury or not has nothing to do with the master, and she only cares about doing her part on weekdays, so Mama Li naturally will not take the initiative to show Su Liuyu the wound.

And Mama is an old man in the palace, who has survived by eating and snaking, and this kind of injury is not a big deal for Mama Li.

But now that the Su family is extinguished, Su Liuyu is sent under the fence, and Mama Li has no money on her body, so she can't buy medicine for treatment, so the injury is aggravated, so she will be seen by Su Liuyu when she pours tea.

"Mama, would you like me to take a look?" Su Liuyu stretched out her hand.

Mama Li thought that she had covered it up very well, but she didn't want this princess to be as careful as dust, so she couldn't help but add two points of admiration in her heart, rolled up her sleeves, and showed Su Liuyu.

She had already done a small treatment, but there was no medication, and with the friction of her sleeves, the wound looked terrible.

"This burn is a little strange...... Su Liuyu muttered.

If you are burned by fire while escaping, the wound should never be on the inside of the arm, near the elbow.

What's more, this wound is not like a burn, but more like a ......

On the inside of Mama Li's elbow, a small number of dark spots appeared, as if she had been poisoned, how could this be?

"Mama, what did you see in the house that day, tell me the truth." Su Liuyu said as she tied Mama Li's sleeves with strips of cloth, exposed her arms and said, "Mama, before tonight, this sleeve must not be put down." ”

Mama Li's face hesitated for a moment, and she agreed: "The slave and maid are old and yellow, and their faces have long been rubbed rough, so it doesn't hurt if everyone gossips." ”

Yes, although the folk customs of Guhua are open, and women can enter private schools and play on the streets, except for the dusty women in the land of fireworks, they are not allowed to show their skin.

Mama Li responded without asking the reason, which made a warm current rise in Su Liuyu's heart.

"The slave maid was wounded before the fire." Mama Li said slowly, "At that time, the slave maid was in a hurry, and accidentally fell and rubbed her forearm, but because the housekeeper was urgent, she went to the account room to report the account without cleaning it properly. When the slave and maid finished paying the bill, the family feast had just begun. ”

"Was your arm burned at that time?" Su Liuyu asked.

"Yes."

Su Liuyu asked again: "This wound is not small, after Mama endured to go to the account room, she didn't go to the family doctor to take a look?" ”

At that time, the slave maid only felt a little wet in her sleeve, but she did not notice any pain. Later, in the middle of the feast, the slave and maid were assigned to the shou bao, so they went to the back courtyard with a group of grandmothers, but because the account room said that I had something left, I ate the shou bao and left the house in a hurry. ”

Don't feel pain?

Su Liuyu pondered for a moment and was puzzled: "Something has fallen, why do you want to leave the house?" ”

"The princess didn't know that the slaves and maids were ordered by the master to buy things and come back to report the accounts, so as to give benefits to the bookkeeper and the housekeeper, and the favored maids around the master could not escape, and the slaves and maids could not escape, thinking that the things sent today were not satisfied with the bookkeepers, so they hurriedly went out and bought them back. When I came back, there was no living mouth in the house, everyone was hacked to death with knives, and the slaves and maids hurried to the neighbors and knocked on the door, but no one opened the door, and then went to the mansion to report to the official, and no one paid attention to it. ”

"Is the place where you fell that day covered with lime?" She remembered that when she saw Mama Li that night, although she was not covered with lime, there was a little lime on the soles and toes of her shoes, as well as the sides of her sleeves.

Mama Li thought for a moment, "Yes, not only the road where the slave fell, but also the lime piled up in many places in the mansion that day. ”

"Have you taken a closer look at the corpses, do they have dark blue skin and black spots on the whites of their eyes?" Su Liuyu saw the hesitation on Mama Li's face, and understood the answer.

Although Mama Li has seen a lot of cruel torture in the palace, in the face of the tragic situation of more than 100 people who get along with her every day being hacked to the ground with knives, how many can calmly check the corpses?

Lime, lime, lime.

Su Liuyu chewed on the word repeatedly, and her mind was spinning rapidly.

Lime can burn people's skin when exposed to water, but isn't it more convenient to cut and set fire to it after poisoning? Why use lime in the first step?

In terms of Mama Li's timeline, the fire burned last. So on behalf of the people, lime was used during their lifetime?

The murderer is extorting a confession?

"They all have silver needles in their fingers, which are not in their fingers, and they are burned with lime, so what does the murderer want to know from them?" Su Liuyu frowned.

Hearing this, Xiao Xin hurriedly rushed to check if there was anyone outside the doors and windows, and wanted to close the windows, but was stopped by Su Liuyu.

On weekdays, the windows are open, but when they are suddenly closed, Zhuang Li and Su Wu's eyeliner will notice, and they will be paid more attention.

Could it be that it is precisely because of this secret that Su Wu, who has been holding back and not moving, finally killed the killer? Or, for so many years, Su Wu has been waiting for this secret clue to appear?

What could it be?

Su Liuyu tried to search in the memory of the original owner, but she didn't have a clue.

She put down the clue for a moment and asked, "Mama Li, tell me what you ate that day." ”

"I ate white rice porridge in the morning, and then I was busy until the beginning of the dinner, and I ate half a longevity peach, and then I didn't eat anything else."

"I haven't eaten for so long, why do you only eat half of Shou Tao?" Su Liuyu said as she pulled up her sleeves to check the inside of her left and right elbows, and then looked at it for Xiao Xin.

Sure enough, except for her who had not finished the rice at the dinner that day, Xiao Xin and Mama Li had a few black spots on the inside of their elbows.

"The slave is sensitive to the fragrance, and the fragrance of the birthday bag peach that day was too strong, and the slave couldn't eat it, so she only used half of it."

Peach-scented, sinan-scented......

Xiao Xin is right, Sinan Xiang is indeed precious, so it is really suspicious that such a large number of people appeared on more than 130 people in the Su family.

Kesi Nanxiang is non-toxic!

"Mama Li, do you know what taboos Sinan Xiang has?" Su Liuyu asked, while taking off the glazed hairpin flower on her head, dipping it in tea, and ordering Xiaoxin to take a piece of cloth, and draw a simple timeline and an overview map of Su Mansion on it.

"Sinan incense should not be burned with air-dried cow dung and rose fragrance, otherwise it will be slightly hallucinating. If you smell it for a long time, you will be dizzy and confused. ”

After listening to Mama Li, Su Liuyu flattened her mouth.

"Which genius has tested this taboo? Mix these things together and burn them? After a pause, Su Liuyu asked again, "Maybe you didn't notice the pain that day, but it was related to incense?" ”

Mama Li shook her head, "The old slave is extremely sensitive to fragrance, if it is really Sinan incense, it will not be impossible to distinguish its taste." ”

If it's not fragrant, could it be the porridge that Mama Li ate in the morning?

But Mama Li was sane at the time, if she was poisoned, in this era, how could she develop a colorless, tasteless, and no adverse reactions that the body could detect, but it could paralyze the body's nerves?

There are too few clues and evidence, and there are too many mysteries to find a clue.

"Xiao Xin, I remember that you only ate a longevity peach that night, and then accompanied me back to the room to rest, right?"

Xiao Xin tried to recall, "Well, you said that you were unwell and had no appetite, so the slave helped you go back first." ”

"Mama Li just got the longevity peach, so she left the house, and there was the uneaten longevity peach, where did you throw it away?" Su Liuyu asked.

Mama Li said: "The slave maid gave it to the beggar at the end of the street. ”

"Do you remember what he looked like?"

"Yes." Mama Li said: "The slave maid saw that he was handsome, and the shou peach slave maid was breaking and eating, so she gave him the rest." He also asked the slave maid, whose family is the birthday today. ”

"Mama, you go to him, I want to see him." After Su Liuyu finished speaking, she changed her words and said, "No, you tell Xiao Xin in detail about the appearance of that child, and let Xiao Xin go." ”

After all, Mama Li's arms are bare, and it is inconvenient to travel.

"Yes." Xiao Xin responded, "When will the slave go?" ”
