"I said that the old man has blood type B, naturally I have my reasons, I don't believe it, I can test it. Su Qi smiled faintly, "Now that the medical system is so developed, it only takes a few minutes to test your blood type."www.biquge.info ”

With that, Su Qi walked to the cabinet, took out a silver needle and a small glass bottle, and turned back to the old man to squat.

"Amitabha, old man, offended. Although it was a little unkind to take blood from the corpse, in order to relieve the crisis of Qiancaotang as soon as possible, Su Qi could only make this decision.

The old man had just passed away, and the blood on his body had not yet coagulated, Su Qi pricked a needle on the finger of the old man's left hand, and immediately blood came out, Su Qi diverted it into the small bottle, and handed it to Wu Ge, saying: "Trouble Master Wu Shi to run, go out and turn left, there is a medical institution not far away." ”

Recently, when he has nothing to do, Su Qi also went online to learn Western medicine, he is not one of those old guys who rest on his laurels, as long as it is beneficial, he will learn it, and therefore he understands the basic knowledge of Western medicine, he knows that in terms of blood type, it is mainly reflected in human chromosomes and genes, and the test is very simple, any hospital or medical point, or even a blood donation vehicle can do it, and the results will be available quickly.

"Okay!" Wu Ge didn't delay in the slightest, took the bottle and went out.

Dahan's face suddenly panicked, if it was really as Su Qi said, the old man was blood type B, then he would have slapped himself in the mouth, no wonder Su Qi would ask him blood type first, it turned out to be a pit dug for this step!

Dahan only understood at this time, but it was too late, he knew this, and he said that he didn't know his parents' blood type, but he was curious, how did Su Qi see that the old man had blood type B?

Xiao Hong and Bai Ning also had this question, both of them waited to look at Su Qi with big eyes, but the time was not right at the moment, they both tacitly agreed not to ask, so as not to cause trouble to Su Qi.

"Before the blood type results came out, I asked the donor a third question. Su Qi turned his head, and his gaze fell on Dahan again.

"You...... What are you going to ask?" After being tricked by Su Qi, Dahan became cautious, and his confidence in speaking was obviously insufficient.

And this is exactly the result that Su Qi wants, in order to recover the disadvantage, the first step is to break up the enemy's attack, and to deal with the enemy, the attack is undoubtedly the most effective, so Su Qi first broke through the psychological defense line of Dahan, as long as Dahan feels that things are not under his control, the next thing will be easy to do.

"The third question, you said that the old man died after taking Bai Shi's medicine, right?" asked Su Qi.

This time, Dahan hesitated for a while, and after confirming that there was no trap in Su Qi's words, he replied, "No...... That's right, my dad just took the medicine on this list and unfortunately died!"

"Fourth question, what are the medicinal materials on the prescription?" Su Qi asked, everyone began to be confused again, Su Qi's dialogue was always very floating, and people couldn't understand his main points.

This is not difficult for the big man, he glanced at the prescription and read it: "30g of raw astragalus, 18g of fried atractylodes, 9g of atractylodes, 6g of yellow lotus......"

Dahan read out the medicinal materials of the prescription in one breath, there are as many as seven or eight kinds, and Dahan doesn't care what these medicinal materials are for, anyway, he insists that the old man died after taking this medicine.

As everyone knows, after he finished reading the prescription, Su Qi asked again: "The fifth question, is there arsenic on the prescription?"

"Arsenic?" the big man looked confused, and the crowd of onlookers, including Captain Lin and several other policemen, were all puzzled, what does this have to do with arsenic?

Bai Ning, the only one with a medical background, was the first to react, she carefully observed the old man, and then she was overjoyed, took Xiao Hong's hand and said, "Arsenic! It's arsenic!"

Although Xiao Hong had never studied medicine, judging from Su Qi's words and Bai Ning's reaction, she could probably guess that this old man might have died of arsenic?

Su Qi immediately turned sideways, letting everyone clearly see the old man's remains, and said at the same time: "Everyone, please see, the old man's face is sallow, the muscles of his limbs are spasms, and his trachea is damaged, which means that there is a problem with his respiratory center, in addition, please look!"

As he spoke, Su Qi pointed with one hand, and everyone's eyes immediately followed the direction of his fingers, and they all fell on the old man's fingers, to be precise, it should have fallen on the old man's fingernails.

The color of the old man's nails was normal, and what was not normal was that he had a few curved stripes on his nails, which just formed the shape of a letter m.

"The old man is emaciated, which is understandable, but no matter what a person's figure is, his nails will not change much, especially this kind of nail lines!" Su Qi seized the opportunity to explain, "This kind of M pattern is a symptom of arsenic by mistake, plus other symptoms, I dare to conclude that this old man died of arsenic, not the medicine that Bai Shi grabbed and killed him!"

Su Qi's words were so loud that the scene was almost audible, and after a while, bursts of discussion erupted in the crowd.

"That young man seems to be right, I have seen the news before, arsenic poisoning seems to be this symptom!"

"What are you doing so much, just look it up on the Internet!"

During the discussion, many people immediately took out their mobile phones and checked on the Internet, and sure enough, they found that the symptoms of arsenic poisoning were the same as those of the old man on the ground, which proved that Su Qi's conclusion was right, and the old man did die of arsenic.

Thinking about it further, the truth of the matter is about to come out, the old man died of arsenic, and there is no arsenic in the prescription, and the result is obvious.

Dahan looked at the situation around him, and immediately felt that something was wrong, his face was as black as the bottom of the pot, this development was not right, it was completely different from the plan!

In the plan, the big man only needs to carry the corpse to the door and make a fuss, wait for everyone to take Bai Ning away, and then threaten Su Qi, how could he have thought that things would take such a big turn? No one told him that the old man died of arsenic, and when he saw the old man, the old man was already dead!

"Type B, it's Type B!"

At this moment, an excited voice came from the door, and everyone turned their heads to look and found that Wu Ge was holding a few pieces of A4 paper, and ran in with excitement on his face.

"Seventh brother, you're right! The old man is indeed blood type B!" After entering the inner hall, Wu Ge suppressed the excitement in his heart and took over the test to show everyone, Wu Ge's mind was still very detailed, and after the results came out, he also deliberately printed a few more copies for the onlookers and the masses to see, proving that he was not cheating.

Everyone looked at it, and the blood type B blood displayed on the blood group test sheet was indeed stamped by a medical institution at the bottom, which was full of credibility.
