Even the imperial doctor didn't find out, so what kind of poison could it be? Hydrogen sulfide...... Potassium cyanide...... These poisons can only be obtained by technical means in modern times, but what about in ancient times?

If these poisons could not be refined in ancient times, what else could poison people except arsenic (commonly known as arsenic) and not find out before they died?

Yeats came from modern times and knew that many elements can cause poisoning, such as mercury (that is, mercury) The ancients used a silver needle to measure poison, which was basically measured. There are also fierce poisoning, patina, lead, iron, etc., which will poison people, in addition to various elements, many animals and plants will also poison people.

Which one will it be? Yeats lifted himself up and retreated from the coffin.

Turning around, he arched his hand and said, "I need the people who have been serving by Yang Xiaogongzi's side, and understand all the eating habits, places he has visited, and the people he has met in the month before he died, is it convenient?" Grandpa Guo? ”

"Boss, you arrange it yourself."

"Yes, father." Yang Shizi bowed.

"Master Pei, before the case is completed, Yang hopes that Yeats will live in the Duchy Mansion."

Pei Jingning agreed.

Yeats didn't even have a chance to refute it.

"What about me?" Teng Chong liked to follow Yeats.

Yang Guogong agreed.

Yeats proposed to add two more, in order to find out the real culprit who killed his son, Yang Guogong was not embarrassed, and both agreed.

In order not to let the outside world see the abnormality, the underworld marriage was carried out as usual.

The best place to learn about a person's past, especially a child of the powerful, is of course the study.

There was no one left and right, Teng Chong asked softly, "Little Brother Ye, everyone has been dead for a year, except for the poisonous spots on the body, I'm afraid this murderer is difficult to find!" ”

If it's easy to find, why do you want them!

Yeats replied softly: "Some cases can be found even after ten or twenty years, but a year is nothing." ”

Teng Chong was so surprised that he almost lost his voice, "Do you have eyebrows?" ”

Yeats glanced at him, "I'm not a fairy." ”

Teng Chong was bald, "Anyway, when I first met you, you pointed out the murderer on the spot." ”

Yeats glanced at him again: "At that time, the traces of the scene were complete, and through the footprints, I measured the height and weight of the murderer, combined with the fresh traces of climbing the wall, and the murderer had arrogant reverse thinking, etc...... A series of actions gave me a chance to find out the murderer. ”

It's really not a fairy guidance!

"What if that is...... I said, what if I can't find the murderer? ”

"If you can't find it, you can't find it, is it possible that Yang Guogong can eat me? He won't find a more powerful adult detective! Yeats glanced at him, "Pedantic." ”

Teng Chong sneered, "Then you're not afraid of others talking about you." ”

"What do you say about me?"

"The case can be solved in your hands, if you can't solve it, won't you be scolded?"

"Hehe......" Yeats said: "It's like seeing a doctor and treating people, can Lang Zhong just because he can't cure a person's illness and erase him to practice medicine?" ”

"......" Teng Chong was speechless with anger, as if it was such a truth, and he felt that something was wrong.

Yang Yanbin is not a child of a high family, the study is not only large, but also has a collection of tens of thousands of books, for an era where books are precious, it is difficult to accumulate such a situation without top wealth.

Yang Yanbin is good at Danqing, and there is a special studio, and the whole wall of the room is his left works, including majestic pictures of rivers and mountains, magnificent mountains and majestic peaks, as well as timeless smoke and rain in the south of the Yangtze River, and beautiful moonlit night drinking pictures.

Sure enough, he is talented, and such a person was actually poisoned, which is really a sigh.

Yeats couldn't help but sigh.

"What do you see?"

Suddenly, a clear male voice sounded in his ears.

Yeats turned his head in fright.

Pei Shaoqing is wearing a moon-white straight-placked robe today, with a moon-white auspicious cloud pattern waist seal around her waist, her black hair tied up, and a simple white jade and silver crown.

When he looked at him sideways, the setting sun shone in through the window lattice, falling on both sides of the bridge of his nose and falling half an inch of dark shadows, the eyebrows were sharp, but the line of the eyebrow bone was unexpectedly soft, and when the eyes looked at him, the edge was full.

"My lord...... "When did this guy stand beside him?" There is a difference between men and women, and Yeats subconsciously avoided it.

"Why are you so fascinated?" Realizing that he had scared his subordinates, Pei Jingning looked at the green rivers and mountains on the wall.

In the form of a long scroll, the work depicts the continuous mountains and the vast rivers and lakes, with mountains dotted with pavilions and terraces, and small towns and cottages in the wilderness, with trees and flowers, birds and animals, depicting fine and vivid meanings.

The scenery is varied, the weather is myriad, the composition emphasizes change in the sparseness, the momentum is coherent, and the artistic conception is majestic, even a layman like Yeats feels that this painting is magnificent, and it is a rare masterpiece.

"If this painting is finished at the end, I am afraid it will be a masterpiece." Yeats sighed, but unfortunately he didn't finish it.

Pei Jingning bowed, "What do you need to find Bai Lang." ”

Yeats subconsciously looked at the white guard behind him, this big guy, can she be moved.

Bai Lang was just about to roll his eyes, Pei Jingning turned his head, he was as frightened as a quail, "Yes, my lord." ”

Yeats made a strange appearance behind Pei Jingning.

Bai Lang didn't dare to be angry or speak, he had to laugh, he was angry and smoking, and he couldn't wait to step forward and pat this stinky boy on the head.

Pei Jingning left.

Yang Guogong's mansion brought dinner, and after eating, Yeats chatted with Yang Yanbin's little servant about family life and learned about him in all aspects.

Until it was dark, the Hao family didn't wait for the movement of the Guogong Mansion, didn't they find out? I wanted to find someone to ask the people of Dali Temple if they had left, but I didn't dare, and I was sweating all over.

Someone discovered, "Hao Niangzi, you ......"

"I ...... I ...... "Hao didn't know what he wanted to do, but he was very confused."

The person who asked the matter found that although Hao's clothes were old, they were cleanly washed, and the person looked fresh and clean, and he had a good impression, so he said, "If you still want to fold ingots tomorrow, go to the back door and stand, I guess you can come in." ”

"Thank you so much, Mama."

"You have to thank yourself, it's your own hands and feet that are likable."

"Yes...... Hao's praise was ashamed, and he followed everyone out the back door.

Until late at night, Yang Guogong didn't sleep, until the little guy replied, "Returning to China, the commentator surnamed Ye of Dali Temple asked questions until midnight before letting Mobao leave." ”

"What did you ask?"

"First of all, I asked how the little boy got along with the prince? I also asked the concubine in the house if there was a geometric ......"

This person suspected that Bin'er died in the fight in the house, of course Yang Guogong also thought about it, and ruthlessly cleared a wave of people in the house, but nothing was found.

It's not a rel.

The little girl replied again: "I asked the little boy again if he has a room and a warm bed girl to compete for favor......"

The old way of checking the law, Yang Guogong's rising hope suddenly fell again.

Seeing that Grandpa Guo was very disappointed, the little guy asked cautiously, "Grandpa Guo, do you still want him to check it?" ”
