Turning over the horse and following the people to the Da Sima Mansion, it was getting dark, and the pedestrians on the street were in a hurry, all wanting to return to their respective homes before the curfew after dark.

Driving all the way to the Great Sima Mansion, the two lanterns hanging outside the door were lifeless, faintly revealing a gloomy and ominous. Jiang Yan has no children under his knees, only four married daughters and a third wife, which is also the reason why Jiang Hai, the king of Xian, used his uncle so heavily in his early years, just because Jiang Yan has no children under his knees, there is no successor, and it is useless to rebel.

Follow the steward into the mansion and walk through the antechamber to the atrium. The steward ordered someone to serve refreshments, and then hurried to the backyard house, in the past, he didn't say a moment of time, and he didn't see the steward appear, Bailiyan (Wei Xian) couldn't help but feel that Jiang Yan was too bad for the friendship of the landlord, and when he was upset, the steward was in a hurry, and he stumbled to the ground, and rushed into the house in fear.

"It's not good, it's not good, the adults are dead!"

Bai Liyan was stunned for a blank in her mind, thinking that she would not die sooner or later, but she would die when she came.

"Steward, what's going on, why did Master Jiang leave so suddenly."

"When I left the house, the adults were all in good shape. Just now, the adult locked himself in the study, and after knocking on the door for a long time, he didn't see the adult open the door, so he pierced the window paper, only to find that the adult had already fallen to the ground. ”

Before the steward's words fell, there was a woman's cry in the backyard, Bailiyan hurriedly came to the inner house with the steward, the study was crowded with maidservants, the crying in the house continued, Jiang Yan's three ladies cried silently and fell next to the corpse.

Jiang Yan fell sideways at the door between the inner room and the main hall, his right side facing down and his left side facing up, his right hand facing 90 degrees in front of him, his feet forked, facing the main hall.

It is believed that he suddenly collapsed while walking from the inner room to the main hall, and then rolled left half a circle to form his current death form. If someone touches a corpse, the corpse is unable to lie on its side on the ground.

When the eldest lady saw that the steward had led the strange man into the inner house, she immediately scolded and said:

"Steward Zhao, who is he?"

"Oh, Mrs. Hui, this is Lord Wei Xianwei, the vanguard general appointed by the king, and he is a distinguished guest invited by the lord, and I don't want to ...... Alas. ”

Steward Zhao sighed, the eldest lady restrained her anger, and said with a sobbing voice:

"It was a guest invited by the master, and the concubine was rude."

Baili Yan gave a slight salute and said:

"Madame, please mourn." Bai Liyan looked at Jiang Yan's corpse again and said, "Madam, Wei used to be a Langzhong in Yicaotang in the city, I don't know if I can check the body of an adult." ”

"The general was originally the famous Wei Langzhong, and the concubine was lonely and unheard."

"Madame's words are serious, and she is famous for four words, Wei really doesn't dare to take it."

The three ladies cried a lot, the eldest lady was in the main room, but she also knew the general situation, and the other two were too unseemly, they just sat on the ground and cried and made trouble, and the eldest lady had to let them be forcibly taken away.

Jiang Yan has one in sixty this year, and now he lives to be sixty years old, which is already considered an advanced age, and living one more day is considered to earn one day, and the quality of life of the elite class is better, and there are many people who live to sixty or seventy, and it is not new to die suddenly.

But dying at the moment when Baili Yan came to the door, it couldn't help but make people wonder what Jiang Yan was going to say tonight. According to Steward Zhao, Jiang Yan was alive and kicking at home every day, saying that he was sick, but in fact he was upset and couldn't eat and lost weight, which undoubtedly increased Bailiyan's suspicions.

After carefully looking around the corpse and making sure that there were no omissions or abnormalities around the corpse, Bai Liyan reached out and reversed Jiang Yan's corpse, facing up. I touched my body temperature first, and it was about the same as the temperature.

Considering that the temperature was hot, the corpse would remain roughly equal to the temperature, and the corpse was a little hard, so it was estimated that the time of death was between thirty minutes and two hours, and an hour and a half ago, which happened to be the period after Steward Zhao left the Great Sima Mansion to go to Yicaotang.

When he lifted his eyelids, his pupils were dilated, and his eyes maintained the last calm before death, but there was a faint look of pain. The face is slightly red, slightly different from the pale face after a normal death, like dying of cardiovascular diseases, such as cerebral hemorrhage or heart infarction, but the exposed arms are also reddish-purple, but not corpse spots.

The closer to the head, the darker the red, the lighter the purple, and the skin on the surface of the legs is a large area of purple, that is, the closer to the blood center, the darker the red, away from the nerve endings of the blood supply center, the darker the purple, which is obviously not a symptom of cardiovascular disease.

Holding his jaw and pushing his lips and teeth apart, he could faintly ask a smell of rice wine, he should have drunk wine before he died.

After checking this, Bai Liyan asked Steward Zhao:

"Steward Zhao, has Master Jiang ever drunk rice wine before?"

"I've drunk it, the old man has been drinking palace wine, and when he left, he still drank it."

"Gong Brew?"

Bai Liyan thought of poisonous wine, it wouldn't be poisoned.

Thinking of this, he got up and went to the inner room, and sure enough, he found two plates of meat on the table, and a jar covered with wine seals, an overturned wooden bowl turned on its side on the table, and the rice wine that had not yet been drunk was sprinkled on the ground, very similar to the scene of overturning when the hair was poisoned. Thinking of Jiang Yan's death, I really can't think of any poison that can produce such a death.

Picking up the overturned wooden wine bowl, I sniffed it carefully for a long time before approaching my nose, except for the mellow aroma of wine, I didn't feel any fishy, bitter, sweet, foul, spicy, and the poisons that can be touched nowadays are basically these obvious characteristics.

At least in Bailiyan's memory, I haven't seen it from any classic book that there is a colorless and tasteless poison that can kill people invisibly, at least within the current technical conditions and cognition, most of them can't make a colorless and tasteless poison.

Putting the wooden bowl back in its place, his eyes fell on the two large plates of meat on the table, one plate was a sliced roast suckling pig, and a plate of white-cut venison, the spices used at the moment were not very rich, fennel and star anise were not in the Central Plains, not even garlic and shallots.

Most of the roast meat is white-cut, and then there is the new soy sauce braised meat, so the smell of the two dishes of meat is not abnormal, except for the color of the roast suckling pig is exceptionally bright, and the bright abnormality makes people appetite.

Bailiyan smelled it carefully again, except for the smell of meat, there was really nothing abnormal, but there must be something wrong with this color.

"Steward Zhao."

"What does General Wei command?"

"Is there a dog in the house?"

"Yes, what is the use of General Wei."

"Go and bring the dog and give this plate of meat to the dog to eat."

Steward Zhao asked puzzledly:

"What does the general mean?"

"Wei suspects that Master Jiang was poisoned."

"What, sir, he was poisoned." The eldest lady was taken aback and hurriedly asked, "How does General Wei know?" ”

"I don't know for the time being, let's go and bring the dog first, and eat this plate of meat to know if it's poisonous."

Steward Zhao hurriedly brought one of the vicious dogs raised in the house, and fed half of the roast suckling pig on the plate to the vicious dogs.

Smelling the aroma of meat, the vicious dog didn't care about the owner's face at all, and pounced on the ground to devour. After eating, Tian shamelessly wagged his tail at Steward Zhao and the others, casting a longing look, which means very clearly, if you are not full, take two more bites.

But before it could be happy for too long, it suddenly fell to the ground with a whimper, and then began to convulse, foaming at the mouth, and about a moment later, it began to fall into a coma and had difficulty breathing. Seeing this tragic situation, the eldest lady was shocked and cursed:

"Come on, come on!"

"What does Madame command?" Zhao said.

"Quickly take down the stove and cook it to me, they must have poisoned and assassinated the adults."

Bai Liyan said at this time:

"The poisoner is not a cook, but someone else."

"How can General Wei see it?" The eldest lady said.

"Wei Mouruo is good, the other dish of venison is not poisonous. If you don't believe it, you can lead a dog to feed it, and you will know a thing or two. ”

Steward Zhao then came to a vicious dog and fed it venison, but two quarters of an hour passed, and he was alive and well.

"General Wei, why is this?" The eldest lady asked hurriedly.

Bai Liyan held his chin and was silent, he could roughly know that Jiang Yan died of nitrite poisoning, and someone deliberately poisoned it, and it was by no means accidental, but how did this nitrite pour get it, this is what makes him puzzled.

Nowadays, there are two main ways to extract salt, boiled seawater and mineral salt.

Mineral salt is divided into well salt and mineral salt, and there are many inland vassal states without sea for mineral salt and well salt. Since Xianguo is a Xianguo, it is naturally the early Liang Dynasty, and the Jiang family is the only Haiyan professional household in the Liang Dynasty, so it is called Xiandi, and after canonization, there is Xianguo. Luhou is currently the largest salt lord in the Xian country, and the king of Xian is relied on.

It is impossible to produce sodium nitrite by boiling sea salt, only in the process of mining well salt and mineral salt, there may be a very small amount of sodium nitrite, which is caused by the reproduction of microorganisms caused by moisture, but the content cannot be high enough to poison people.

With current technology and knowledge, it is obviously unlikely that sodium nitrite can be synthesized chemically.

The reason why it was concluded that the murderer was not from Jiang Yan's mansion was that the roast suckling pig came from outside the mansion.

Due to the long preparation cycle of roasting suckling pig, it takes about a day to handle, marinate and repeatedly color the suckling pig, and it also takes half a day to roast, and a special stove is also needed.

Therefore, even if it is a powerful family, it may not have the conditions for production, let alone eat and make it even more impossible. Moreover, since last year, King Xian has ordered a complete ban on the slaughter of young pigs throughout the country, so that pigs can grow meat to supply the army, except in special cases such as military rewards and gifts.

In the place where you can buy suckling pig in the city of Chenling, in addition to the palace, only the Xuanting Pavilion opened by the Marquis of Xuanting can buy suckling pig, just because he is the brother-in-law of King Xian, he has this privilege.

Thinking of this, Bai Liyan couldn't help but feel a chill down his spine, and he asked:

"Steward Zhao, the suckling pig is from the Xuanting Pavilion?"

Steward Zhao affirmed:

"Exactly, I ordered my subordinates to go to the Xuanting Pavilion to buy half of the suckling pigs, all of which are here for adults."

"That's right, the poison in Lord Jiang is salt poison, which comes from outside, not someone in the mansion who poisoned it."

At this time, the eldest lady was taken aback and said:

"Xuanting Pavilion, this is not!"

The eldest lady's eyes were frightened, and at this moment, anyone could think of what the relationship between Xuan Tinghou and Baili Yan was.

Steward Zhao Jin hurriedly took two steps back and said vigilantly:

"General Wei, you!"
