There are many ways to kill, in addition to poisoning and murder, you can also make devices to manipulate people from a distance. Pen? Interesting? Pavilion wWw. ｂiquge。 info leads to the cause of illness and death.

But whether it is to make instruments or guide the cause, it is more time-consuming, Zhao Qi wants to kill people quickly, he can only choose to poison and kill.

If there is no time limit, Zhao Qi can completely guide the cause and make people sick and die.

There are many kinds of drugs, among which the chemical drugs are the most deadly.

"Sodium cyanide, potassium cyanide, mercury oxycyanide......" Zhao Qi kept thinking about the chemicals he could get.

Medicine, there is a very important medical chemistry, and Zhao Qi wants to make drugs, but it is still very easy.

"Just choose sodium cyanide, Class A inorganic matter is highly toxic, and you will die if you touch it." Zhao Qi's expression was calm and he didn't feel guilty at all.

To make sodium cyanide, some raw materials and equipment are required, and the most important material is sodium ferrocyanide.

Sodium ferrocyanide is slightly toxic, which can be obtained directly.

As for the equipment, it is simpler, test tubes, alcohol blowtorches, test tube clamps, small spoons, funnels, filter paper, beakers are sufficient.

Zhao Qi looked at the dozen or so people in the class and sighed slightly, he couldn't kill people by poisoning for the time being.

Making sodium cyanide is much faster than other methods, but it still takes some time.

"Are you done eating, let's go after eating, I'll go back and help the potatoes make up the bed at noon today, so I can't accompany you." Zhao Qi and Liang Rumeng finished eating and spoke, Liang Rumeng nodded obediently, and the two left the classroom and returned to the dormitory.

sent Liang Rumeng to the dormitory, Zhao Qi immediately left the dormitory, turned around and left the school.

Haihe High School is under closed management, and boarding students are not allowed to leave the school, but this problem is not difficult for Zhao Qi, Zhao Qi easily left the school and went to buy some ferrous hydrogen chloride.

Subsequently, Zhao Qi was ghostly, and he quickly shuttled through the streets and quickly returned to school.

At noon, there was a break of more than two hours, and there was still an hour after Zhao Qi returned to school, and he quietly sneaked into the chemistry laboratory, borrowed the tools of the chemistry laboratory, or made sodium cyanide.

The manufacture of sodium cyanide is a very dangerous thing, and it is generally made by industry, and it is very difficult to make it privately.

Moreover, sodium cyanide is highly toxic, and if the person who makes it is not careful, it will kill.

Sodium cyanide, ordinary people swallow 40 milligrams, it can be fatal, and the amount in Zhao Qi's hand is enough to make a pound of sodium cyanide.

So much sodium cyanide is not a problem to poison a school.

Ordinary people, if they touch it, they will die. But Zhao Qi is not an ordinary person, Zhao Qi, as a cultivator at the peak of condensation, coupled with the body that opens the soul condensation and the training of the soul power, sodium cyanide does not play much role in him.

With his strong strength, Zhao Qi really refined all the sodium ferrocyanide in his hand and obtained more than 300 grams of sodium cyanide. As for the other 200 grams, they were discarded because they were not very skilled.

The cultivation is high, and the refining speed of sodium ferrocyanide is also fast. (You can refer to the ...... of the poisoning incident in a university)

When Zhao Qi left the chemistry laboratory, it was not yet two o'clock, he checked the chemistry laboratory and found that the chemistry laboratory did not have any cameras or anything like that, so Zhao Qi destroyed all the data with peace of mind and left with peace of mind.

Leaving the chemistry room and returning to the class, Zhao Qi found that there were still seven people in the class less than two o'clock, but what reassured Zhao Qi was that there were no Zhao Jingfei and Nie Qianqian among the seven people.

Most of the seven classmates were crawling and sleeping, and Zhao Qi returned to his seat, and he began to think about who he was going to poison.

Now, Zhao Qi didn't know how many people in the class were doubting him, but since he came back from the second quarter in the morning, there must have been several people doubting himself.

Zhao Jingfei, Zheng Ya, Feng Jie.

Zhao Qi only knew about the three members of the Blood Book, and the remaining three members of the Blood Book did not know.

"Grace ....."

"Choose Zhao Jingfei!" Zhao Qi made up his mind, Zheng Ya's head is not bright, and someone should have seen it.

And Zhao Jingfei is too cautious, Zhao Qi needs to yin him.

Zhao Qi directly chose Zhao Jingfei's tablemate, and by doing so, he was exposing Zhao Jingfei to the eyes of the members of the Blood Book.

As for whether the members of the Blood Book believe it or not, hehe, in this story world, it is better to kill tens of millions by mistake than to miss one.

Zhao Qi did not follow the idea of psychology and choose the best candidate from Zhao Jingfei's perspective. Instead, he went straight to the point, that is, to poison Zhao Jingfei's tablemates.

Zhao Qi was afraid that the other members of the Blood Book were all pigs, and if they went around, they wouldn't be able to see it.

The students in the class were all sleeping soundly, and it was a time when these students were sleepy.

Zhao Qi came to Zhao Jingfei's seat, he put a little sodium cyanide powder in the water cup of Zhao Jingfei's table, and put a little sodium cyanide in Zhao Jingfei's drawer.

When sodium cyanide encounters water, it will undergo a hydrolysis reaction, but the amount that Zhao Qi put in is very small, so the reaction is very small, and it is impossible to find it if you don't stare at it.

After Zhao Qi put the sodium cyanide into the water cup, he quickly closed the bottle cap, and then put the water cup in place as if nothing happened.

Doing all this, Zhao Qi left the scene without hurrying, Zhao Qi's movements were not fast, and he was not worried about being discovered.

The classmates in the class are all sleeping, there is a difference between real sleep and fake sleep, Zhao Qi, as a doctor, he can still easily distinguish these, unless there are members of the blood book in this group.

Leaving the scene and leaving the class, Zhao Qi wandered around the cafeteria and found that the words on the potato in the cafeteria had disappeared.

I guess someone got it.

took out the power bank from the commissary, and after Zhao Qi charged his mobile phone, he left the commissary and returned to the class without hurry.

The time was already more than two o'clock, and the students in the dormitory had already begun to walk towards the class, and after Zhao Qi walked to the class, most of the students in the class had already come.

As for today's protagonist Zhao Jingfei and his tablemates, they have not yet arrived.

It wasn't until the bell was about to ring that Zhao Jingfei and his tablemates came to the class, and the two walked in talking and laughing.

Sodium cyanide has a little taste, but the sodium cyanide that Zhao Qi put in Zhao Jingfei's drawer is very hidden, and he is not worried that Zhao Jingfei will be able to find it.

The college entrance examination is the seventh or eighth of June, and it is now the beginning of April, Haihe High School doesn't know which place it is, but the temperature has reached about 25 degrees.

It's almost summer, and in such weather, many girls have begun to intentionally show off their thighs.

Zhao Jingfei sat at the same table with him to his seat, Zhao Jingfei's table mate probably talked a lot, and felt thirsty, he picked up the water cup on the table and unscrewed the lid......
