"Without a trace? This official has been in charge of Jiuyuan Mansion for ten years, but he has never heard of this kind of poison. Governor Li frowned.

Song Nian smiled, thinking to himself if I am an expert or are you an expert? You know, you're here to do the autopsy, not me here.

She didn't answer Governor Li's question, but said, "Just ...... Everyone believes that the children of the Wang family here died of suffocation. ”

Governor Li and the others all nodded slightly, and even more people from the Wang family said disdainfully: "This is located underground, dozens of people are locked up here, and the entrance is sealed, so it is natural to suffocate to death." ”

Song Nian smiled faintly and looked at the old servant with a sad face: "Old man, what do you say...... Will Mrs. Wang lock up his children in such a place and suffocate them to death? ”

The old servant sighed and said slowly, "Old lady...... Naturally, this is not the case. Here, of course, it can be ventilated. ”

With that, the old servant pressed a few times on the wall of the underground chamber to reveal the upward vent.

These vents, the size of a fist, can't get in, but they keep air circulating. Song Nian stretched out his hand and tried it, the air flow was extremely subtle, but it kept the air flowing.

Then, the old servant continued: "The old lady also thinks that when they were sent here, they had already drunk the drug, fell asleep, and breathed slightly, so they didn't completely open the vent. ”

Song Nian nodded slightly, and then said to the old servant: "Above this vent, there are those rooms that look much smaller than other houses, right?" ”

The old servant nodded: "Lord Song is right, the reason why those rooms are thicker is that the relationship between these vents is hidden.

"Even so, but in case...... What about the old lady's miscalculation? Did these people really die of suffocation? Governor Li frowned. I was slightly dissatisfied with Song Nianhengsheng in my heart, after all, these people are dead, and the old lady of the Wang family is also dead, what do you care about so much?

Song Nian smiled and said lightly: "Governor Li, this matter is very important. ”

Governor Li frowned: "Master Song, you might as well talk about it in detail?" ”

Song Nian pointed to the nearby fire candles: "Lord Li should know that in all kinds of pits, including such rooms, if the fire candles in the room are not burning, it means that the air is dirty, and people will suffocate to death in this kind of dirty air." ”

Governor Li frowned: "I naturally know about this matter, and there have been several cases in Jiuyuan Mansion in the past. But you mean? ”

Song Nian smiled: "When we enter this place, this fire candle will be lit, which can show that the air here is not dirty, and it will never suffocate people to death." ”

With that, Song Nian walked to the side of the corpses: "So...... How did these people die? ”

Chu He frowned: "Master Song, the cause of death of these people is important?" What does it have to do with the death of Mrs. Wang? ”

Song Nian was in good spirits.

Chu He seemed to be questioning, but in fact, he was helping Song Nian and giving Song Nian room to play.

Song Nian immediately said: "Because...... The way the old lady Wang died was exactly the same as these people! ”

"Exactly the same?" Chu He stepped forward quickly and looked through the firelight.

Governor Li also followed.

"Sure enough, the body surface is red, the ears are red, and the lips are purple...... "Governor Li was a little surprised: "Dozens of corpses are exactly the same as if they died." ”

Song Nian said lightly: "So, these people died from the same poison. ”

Moreover, it is a kind of poison that will become famous in later generations.

"What kind of poison is it?" Governor Li frowned and asked.

Song Nian smiled and didn't answer, but said to the second young master of the Wang family: "You just said that the medicine bottle of the old lady Wang was replaced by you?" In comparison, the medicine bottle is still on you. ”

The second young master of the Wang family nodded hesitantly.

"Take it out." As soon as Song Nian stretched out his hand, Wang Shoucai hesitated to take it out and handed it to Song Nian: "What do you want this for?" ”

Song Nian lifted the cap of the bottle and sniffed it, and sure enough, there was a familiar smell.

"This bottle of medicine is the poison that kills."

"What, this bottle? Not that bottle of fish gall? Governor Li was also stunned, how could this be?

Song Nian smiled: "The so-called poison is not to die immediately after taking it, but it takes a little time." After eating this bottle of poison, the old lady Wang was poisoned by death, but it was not until he pretended to take fish gall bladder...... This bottle of poison came at and took his life. ”

"This ...... It's too incredible! Governor Li frowned: "This kind of thing, it is difficult for this official to write it into the file." ”

Song Nian said lightly: "This is very simple, just find a living creature and try it." ”

Try it, just try it.

Let the Wang family find a few meat dogs, and then carry all the corpses out of the basement.

Seeing so many people dead, the Wang family was extremely commotionous for a while.

But after all, there were several highly respected people of the Wang family present, and after a few scoldings, the Wang family finally stopped making noise.

And Governor Li even more majestically announced that these people were poisoned to death, and now they have to verify the poison!

Although the Wang family is fierce, they heard that their family members were poisoned at this moment, and the official is verifying the poison, and they are immediately much more well-behaved.

In the face of unfamiliar territory, these people also maintained a natural awe.

Soon, Song Nian found a piece of meat, smeared the poison in the medicine bottle, and distributed it to a few dogs.

It was only half a cup of tea, and the dogs wailed a few times one by one, and fell to the ground and died.

The deaths were all identical, with blood-red spots on the bodies, red ears, and purple lips......

The violence of the poison and the weirdness of the death made the onlookers of the Wang family let out a burst of exclamation.

Seeing this, Governor Li nodded with satisfaction, and asked in a low voice: "Master Song, this poison has been tested, and it is indeed the poison that made the old lady Wang and some people of the Wang family die." It's just that...... Why do you have to do this in public? ”

When Song Nian heard this, he said calmly: "Master Li, it's really ...... This poison is too strange, if it is not demonstrated to the Wang family in public, I am afraid that the Wang family and the superiors will not believe it. After all...... The Wang family, but two generations of emperors, can't make any mistakes. ”

Governor Li thought so deeply and praised: "I really didn't expect that Master Song is so proficient in the way of being an official. ”

Song Nian smiled, but what she thought in her heart was - of course the old lady wants to make this secret public! If only a few people or a dozen people know the symptoms of poisoning, they are afraid that they will be wiped out in minutes!

Proliferation, proliferation is security.

It is best that the people of the entire Great Eternal Kingdom know this poison and the method of death, and they are not considered to be people who "know secrets", and naturally no one will kill them for the sake of "secrecy".

This is the wisdom of survival.

However, just when everyone was amazed, Chu He poured a basin of cold water on it.

"The poison is confirmed, but what about the murderer?"
