210 Find the source of poison

The rescue work is over soon.

Except for the patient who died at the beginning, the rest came alive.

bite--

The system task is completed, the host has won 1 million system experience and won a mysterious prize at the same time. Is the prize drawn now?

Lottery!

Ding-Congratulations to the host for obtaining ten grenades!

Grenade?

How could it be this thing?

Su Yang didn't react for a long time.

However, the system's rewards are generally of great significance, but they are not visible yet.

OK, then let's talk about it later!

Su Yang sighed and soon returned to the real world. At this time, he was so tired that he was about to fall down.

But he couldn't lie down.

Next, he has another very important task, which is to investigate the cause of poisoning.

"Find a car for me, I have to go back." Su Yang said to the hospital director.

"Okay!" The dean nodded and soon found a car to come over.

"Teacher, I'll give it to you!" said the dean.

"If you stay here, there are still many things that you need to deal with later." Su Yang said.

"Okay teacher!" The dean nodded with a respectful attitude.

If the previous respect was because of Xiao Balang's order, then at this moment, his respect for Su Yang was deeply rooted in his soul!

The dean quickly found a doctor with good driving skills to drive Su Yang.

The car started and quickly drove out of the hospital gate.

"Doctor, wait!" A group of soldiers suddenly rushed over and the person in charge shouted.

These soldiers were armed with guns and live ammunition, and they all sent the patients to the past.

Su Yang poked his head out to look at the soldier.

"Doctor, we will send you back." said the soldier in charge.

"No need!" Su Yang shook his head.

Montenegro City is still very safe, and Xiao Balang's security measures are quite in place. Besides, he is not an ordinary doctor, he is a combatant doctor, with a scalpel in one hand and ninety-five steps in the other, and he can do anything.

But the soldiers were very persistent, and they said in unison: "Doctor, let us send you it! Our captain said, you are our patron saint, and you cannot have any problems!"

Su Yang glanced at everyone and had to say, "Okay!"

Soon, a group of motorcycles roared onto the road, some opened the road in the front, some ended in the back, and some guarded on both sides.

These motorcycles were purchased specifically from China by Xiao Balang followed Shi Qinghai's advice and were all Jialing motorcycles with certain off-road functions. One motorcycle can be used to ride two people. Of course, if you can have the ability of A San, it is OK to ride four or five.

Most of the Heishan Belt are mountain roads, and many places have no roads at all, and the transportation is inconvenient. With these motorcycles, Xiao Balang can form a fast mobile combat force, with two people on each motorcycle, one is responsible for driving and the other is responsible for fighting.

This was originally just a casual statement from Shi Qinghai. Unexpectedly, Xiao Balang's effect was very good after implementing it for a period of time. The combat ability of the Black Mountain tribe leaped straight from then on, killing other tribes. The enemy would be frightened whenever he heard the roar of the motorcycle.

But at this moment, this motorized combat squad became Su Yang's guards, some of which were clearing the way in front and some were guarding on both sides.

The convoy roared and flew past the road. The people next to him were staring at each other and stopped to watch. Xiao Balang didn't have such a big style when traveling. Who was sitting in the car? Such a big situation?

Everyone is very strange.

In fact, Su Yang knew that this was not good, but now it is an extraordinary period, so he couldn't care about that much!

He returned to Xiaobalang's base as fast as possible.

The first thing is to rush into the kitchen and find the source of the poison.

Because of a collective poisoning incident, the dining scene and the kitchen were in chaos, which was very bad, but Su Yang quickly found a large bag of salt.

This kind of salt that costs five kilograms per bag is the favorite one among the people nearby. Judging from the packaging, this bag in the kitchen is exactly the same as the ones other ordinary people buy, and there is no difference.

The salt of the Black Mountain tribe was originally imported from outside, and it was a bit chaotic and sold by all kinds of vendors. Later, Xiao Balang followed Shi Qinghai's advice and set up a salt monopoly. On the one hand, it regulated the market and on the other hand, it also ensured safety and earned funds. It was not only food safety, but also market safety. After the unified sale, there were few people speculations and prices were raised, and the people responded very well.

Su Yang quickly entered the system space.

In the real world, he does not have any medicines or equipment for testing, but in the system space, he has whatever he wants, which is very convenient.

He first had to test the ingredients of these salts.

Although he suspected it was nitrite, it was not easy to say, and experimental data must be found.

Suyang was determined by naphthalene ethylenediamine hydrochloride method.

In fact, there is also a solid Grignard reagent method.

However, that method is suitable for the qualitative determination of nitrite in food.

The measurement results can be used as an important reference for preliminary judgment of the nature of the event, but cannot be used as a basis for determining the nature of the event.

Spectrophotometry is generally used in China to determine the nature of major emergencies.

However, this is not in China, there are not so many rules and regulations, and there are not so high standards. Just be simpler. Therefore, Suyang uses naphthylenediamine hydrochloride method, which is a method that can quantitatively and semi-quantitatively measure nitrite.

Suyang absorbs sodium nitrite standard use solution    0.00ml, 0.50ml, 1.00ml, 1.50ml, 2.00ml, 2.50ml       Add water to 5ml                                                                                        �

Pretreatment solution for sample 2.5ml, 60mg of Gagrignard reagent, mix well, heat to promote dissolution, let stand for 2 minutes, then take it out and cool to room temperature.

......

After some measurement and calculation, Su Yang came up with the results.

He was shocked when he saw the result. The nitrite content in this salt bag was as high as 95%.

In other words, this is definitely not because of careless mistakes and mistaken industrial salt for table salt, but it is definitely something that someone deliberately does, and the content of nitrite in industrial salt is not so high.

Therefore, it can be said that this collective poisoning incident is a conspiracy.

The enemy wanted to sneak in and do damage, but Xiaobalang had a very good management of Montenegro, and the people of Montenegro were very supportive of Xiaobalang, so the enemy had no idea how to start and it was difficult to enter successfully. There was no way to poison or something. Finally, they thought of using nitrite instead of salt.

This method has many advantages. First of all, it is not easy to be discovered. Nitrite and salt look exactly the same, and most people cannot distinguish it at all. Moreover, this kind of thing is not easy to attract the attention of others. In addition, once eaten, the amount of poisoning will be large, and it can even be accurately poisoned. For example, as long as you sell this salt to Xiaobalang's royal chef, you can directly poison Xiaobalang.

In addition, poisoning is committed by Xiaobalang's own people, so there is no need to worry about danger. They just need to sell nitrite to Xiaobalang's chef.

After figuring out these things, Su Yang immediately returned to the hospital.

Just at this moment, Xiao Balang also woke up.

Su Yang briefly told Xiao Balang about the situation he had investigated.

Little Balang was stunned for a moment when he heard this.
Chapter completed!
