I was just solving crimes, how could I become an immortal?

Chapter 68 If you don’t die, how can I test for poison?

Investigate the source of the poison.

This idea is not a bad one. After all, Dr. Zhong is still here, so if he knows what kind of poison he has, there is a high chance that he can be cured.

But it's not that they didn't try, it's that they couldn't find the source of the poison at all.

The first case of poisoning occurred ten days ago. At that time, water sources, food, etc. had been investigated, but unfortunately nothing was found.

Just five days ago, the second case, the third case, the fourth case... the number of cases began to increase crazily, catching the Feng family off guard.

They also thought that there was something wrong with the house and planned to move their family away. However, at that time, another bottle case and bombing case broke out in Shangjiang City.

In this chaotic situation, this group of people who seemed to be infected with an infectious disease were naturally blocked from the city by the Shangjiang garrison.

Even if it was the family of the Minister of War, the imperial court only arranged for the agency to come to assist and searched the house inside and outside, but unfortunately nothing was found.

"Just because they can't find it out doesn't mean I can't do it. Come on, tell me the symptoms of this poison."

Cao An quickly entered the investigation mode and analyzed the case with everyone.

Dr. Zhong is also a kind-hearted doctor and listed all the current symptoms one by one.

"Judging from the pulse, it should be symptoms of poisoning. But this kind of poison is very rare. So far, vomiting, coughing up blood, coma, convulsions, etc. have appeared. Everyone's symptoms are different."

"After the toxin invades the bone marrow, the person is hopeless. I can only temporarily suppress the spread of the toxin, but if I can't find the source of the poison, I'm afraid there's nothing I can do to save it."

As he spoke, Mr. Feng stood up suddenly and yelled crazily.

"Oh, this is another symptom, hallucinations. Currently, only Mr. Feng has this symptom."

To say that this poison is really harmful to people, you see, the old man is still stimulated by this hallucination despite his age, and he starts yelling nonsense: "Xiaolian, I miss you so much! Xiaolian."

When Cao An heard this, he felt a little moved.

"Xiao Lian should refer to the old lady of the Feng family. She was still thinking about her wife when she was dying. She is really more loyal than ever!"

"Cough cough."

Pang Shi coughed from behind and bumped Cao An slightly with his elbow, signaling him not to continue talking.

"what happened?"

Pang Shi whispered in his ear: "That Xiaolian is his grandson's child bride."

"..."

Is the world of rich people so chaotic?

Putting aside distracting thoughts and returning to the topic, the symptoms of poisoned people are different, which means that the poison is obviously biased.

If someone really poisons, it is impossible to prepare hundreds of different poisons and then use them one-on-one. The poisoning process is really weird.

An uncle from the Feng family next to me, who had mild symptoms, said angrily: "In the past few days, I have been eating and living with my servants, but I have been poisoned. Those servants are completely fine. It is simply unreasonable."

They did all the protection they could, and even changed the guards twice, but it was a pity that it was to no avail.

Cao An pondered for a while, and then he probably had a direction in his mind. He clasped his fists at Imperial Physician Zhong and asked, "The Imperial Physician has superb medical skills. If I know the name of the poison, can you prepare an antidote?"

"If I knew what kind of poison it was, I would definitely have a solution."

The Imperial Medical Office serves the royal family, and it is a place where experts from all over the world are gathered. Prescribing the right medicine for the disease is something they think is simple.

Cao An nodded and asked Feng Zhao, "Has anyone in the courtyard died from this poison?"

"Yes, more than a dozen people in the hospital have died of the disease. Because they were worried about infection, they put them all in the backyard and prepared to find a hill to bury them."

"Take me to see it. It's best if it's someone who died not long ago."

Seeing Cao An's serious look, Feng Zhao wanted to persuade him, but he didn't know how to respond.

The most important thing now is to detoxify and save people. Why do we suddenly need to check the bodies again?

I don't understand, but Cao An is already his last hope. Looking at the expressions of Pang Shi and Sanyang, we can tell that they admire Cao An, and maybe this is really an opportunity.

With this in mind, Feng Zhao also led them to the woodshed where the corpses were piled.

Judging from the appearance of the corpse, the earliest possibility is that it has been dead for a while. The smell of the corpse is very pungent.

But given the current situation, the city was in chaos and the Feng family was falling ill, so they really couldn't spare the time to bury them. "It's just right to be buried. I want to investigate the body."

Cao An once again mentioned the investigation, which surprised everyone. What is there to investigate about the dead body?

"Of course, there is a post-mortem examination, which is used to determine the condition of the deceased through the changes in the five internal organs." Dr. Zhong took the lead to speak for Cao An.

When he first arrived, he had seen the Six Gates and the Demon Slayer Department coming, but those people looked like they were just going through the motions. They looked over everything before leaving in a hurry, as if they were afraid of being infected. Average.

Looking at Cao An again, he was preparing to dissect the corpse conscientiously. At least his attitude was much better than those people, but he didn't know the dissection...

"Anatomy? No need for anatomy. Dr. Zhong can just lend me a silver needle."

"Silver needle?" Doctor Zhong was a little confused.

Are you using a silver needle to check the location of poisoning? But the toxins in the body of the deceased have invaded the five internal organs. How can it be measured?

I don’t understand it, but Dr. Zhong is still willing to borrow it.

"Which size silver needle do you need?"

"Any size will do, as long as it's a silver needle."

The completely careless attitude made Doctor Zhong's face full of doubts.

Especially after Cao An took the silver needle, he pierced the corpse's shoulder without hesitation.

"Ah!" Doctor Zhong exclaimed in a low voice.

Everyone hurriedly came forward to ask: "Imperial physician, is Cao An's injection very subtle?"

Doctor Zhong shook his head: "It's not very subtle."

"Then why did you scream?"

"Because this needle didn't hit even half of the acupuncture points. I haven't seen such acupuncture for a long time."

The completely unreliable behavior made everyone in the Feng family despair again. It seemed that Cao An didn't understand medical science at all. He just took a random injection. Can he really know what kind of poison he got?
  Of course.

'Turn on [Silver Needle Poison Test]. '

"The silver needle poison test is completed. The poison on the corpse is: three-leaf three-leaf spider poison."

Using silver needles, one can find out what kind of poison was in the body of the deceased.

Cao An's new talent was unexpectedly put to use so quickly.

After coming to the conclusion, Cao An naturally immediately told Doctor Zhong: "This corpse has been infected with [Three-Leaf Three-Leaf Spider Venom]."

They got an injection for no apparent reason, and got a poisonous name for no apparent reason. Could it be that Cao An was teasing them?

"That's right, that's right!"

Doctor Zhong pondered for a moment, and suddenly said excitedly: "The symptoms of this corpse are exactly similar to [Three-leaf Spider Venom]. I have suspected it before, but the symptoms of the other poisoned people are not right..."

Doctor Zhong looked hesitantly at the other deceased people. Each poison corresponded to one symptom. Could it be that the poisons of the other deceased people had changed?
  "This is [two-leaf three-leaf spider poison], this is [three-leaf four-leaf spider poison], and this, this is [five-leaf seven-leaf spider poison]..."

Cao An used silver needles and began to prick each corpse randomly.

He couldn't see the number clearly, but he could accurately determine the name of the poison, which was completely consistent with the symptoms of the deceased.

"It's really amazing! I have never seen such exquisite acupuncture. Mr. Cao, are you willing to join our Imperial Medical Office?" Imperial Physician Zhong was impressed by Cao An's ability.

It is rumored that there is a saying in the medical field that a needle can cut off yin and yang. Is it Cao An or a medical master who is hiding in the city?

Sorry, I'm not.

Seeing Cao An's ability, everyone in the Feng family couldn't help it. A patient dragged his sick leg and rushed over at a trot.

"Master Cao, please help me test it. What kind of poison have I been exposed to?"

Cao An glanced at him up and down: "How can I test for poison if I don't die?"

"???"
