Almighty Blessing Pack: Traveling through troubled times with a microscope

Chapter 57 The Mystery of High Purity Arsenic
The eldest brother took down the covered microscope from the attic in the backyard, and put it on the table by the door according to Yinbao's request, and opened all the windows to ensure sufficient light source.

Yinbao wiped his hands clean, put on his gloves, and said unhurriedly, "Within half an hour, I will give it to you two, and also to my brothers and sisters in Shuixiangju, an explanation!"

Li Jiang clutched his trousers, grinned in pain, glared viciously at the house slaves who couldn't speak just now, and stared nervously at Yinbao.

Yinbao calmly took samples of all the dishes, rice, and the food in Mrs. Li's bowl, bottled them, poured them into clean water, and shook them thoroughly, then took a tube of his wife's blood, and asked Li Jiang to prepare six silver needles .

Yin Bao carefully observed his wife's body. Her nails had white and wide stripes, which lost their luster and became thick and brittle, which was consistent with the signs of arsenic poisoning.

Then, she inserted the silver needles into food and tea in order, but she did not find that the silver needles turned black.

After that, Mrs. Li's blood samples, as well as the stomach and throat were inserted, and no blackening was found.

This discovery was unexpected by Yin Bao.

Li Jiang stood up anxiously and was about to leave, "It seems that my wife is suffering from an emergency, and she is not poisoned! Someone, bring Madam back!"

"Wait!"

Yin Bao pressed the table, and the guys gathered around one after another to prevent the servants from approaching.

"Mr. Li opens and closes his mouth. If there is no problem, there is no problem. If there is a problem, there is a problem. My heart can't stand such a toss in this small business!"

Li Jiang frowned, "You can't find any evidence!"

Yinbao picked up the bottle of blood specimen, focused his eyes, and said in a firm and calm tone, "Who said I couldn't find it?"

Yinbao took a smear of Mrs. Li's blood sample, observed it under the microscope, adjusted the coarse focus helix, then switched to a larger objective lens, and then adjusted the fine focus helix, and the clear sample was immediately displayed in front of his eyes.

By counting the white blood cells in the specimen, Yinbao found that under several different fields of view, they all got consistent results, that is, Mrs. Li's white blood cells now far exceed the normal value.

Such a result also confirmed that she was indeed poisoned. Combining all aspects of her performance, the possibility of arsenic poisoning was the greatest.

But why didn't the silver needle turn black?
Yin Bao rested his chin lightly with his right hand, lowered his eyes, and carefully thought about the sampling process before and after, and whether he had missed any important details.

Her gaze swept to the street outside, many young women standing watching the bustle, painted with bright red cinnabar, gesticulating inside.

She suddenly remembered that when she had not left the shop just now, she saw Mrs. Li had the habit of applying cinnabar while eating.

Yin Bao hurriedly searched for the brightly packaged box of cinnabar on her body, but there was no trace of it.

"Your madam carries a box of golden cinnabar with her." Yin Bao mooed sideways at a domestic slave who was closest to Mrs. Li before, seeing that he was about to retort without hesitation, and asked, "Don't try to lie, if I You guessed it right, it was something used by the royal family in Kyoto."

"There shouldn't be many boxes in this Mizhuang!"

The house slave avoided eyes and secretly glanced at Li Jiang, but Li Jiang pretended to be in pain and rubbed his head without saying a word.

Her newlywed wife was murdered, but Li Jiang acted like this. Yinbao already understood the whole story, but the incident happened in Shuixiangju. Today, even the Heavenly King and Lao Tzu stood in front of her. Church will be innocent.

They hid the box of cinnabar, there must be a ghost, Yinbao took off the remaining cinnabar on Mrs. Li's lips, soaked it in water and tested it with a silver needle, it still didn't turn black.

There were evil smiles on the faces of several house slaves behind him.

"Since it's not poisoning, then the restaurant Shuixiangju seems to be bewitched!"

People outside the door were discussing a lot, Yin Bao was holding a pure white silver needle, and a bold idea suddenly appeared in his mind.

The reason why silver needles can be used for drug testing is because ancient poisons, especially arsenic, were often not 100% pure, and were often mixed with a lot of sulfur.

Now the wife's poisoning is not caused by pesticides or rat poison, because there are no neurological symptoms.Could that be pure arsenic trioxide?
If this is the case, then the poisoner's method is really too clever.

At least in the production of arsenic, it already has Tengda technology far surpassing that of the Jin Dynasty.

Yinbao took some acid water, mixed it with the cinnabar scraped from the lady's lips, and slowly baked it on the candle. After a while, black and translucent flakes appeared in the cinnabar, just like a mirror.

This discovery surprised Yinbao, indicating that the cinnabar did contain arsenic with a very high purity, so high that silver needles could not detect trace amounts of sulfur in it.

Then she tested the meals separately, and found that only the part of the wife's bowl that was stained with cinnabar could detect the arsenic mirror.

(Arsenic mirror is a black and bright mirror-like product formed after acid water and arsenic react.)
"The culprit is the box of cinnabar. The poison is high-purity arsenic."

Yin Bao turned around and put the reagent bottle on the shelf on the table.

Li Jiang was obviously taken aback, as if he had never thought that Yin Bao could discover the poison.

The house slave on the side was still not convinced, "Why do you say that the poison is in the cinnabar, and I also said that you deliberately put it in the wife's bowl!"

The corner of Yinbao's mouth curled up into a smile, seeing them rushing to fight back in such a panic, she felt a lot more at ease.
