Great Song

Since Qingfeng and Mingyue strongly demanded it, Zhen Qiong followed suit and recruited a few more boys to burn fire.This time it was simple, he didn't go to Yixue, and let Qingfeng handle it for him.Anyway, choose to be literate, good at arithmetic, and dexterous.When you come to the Taoist temple, you should be an apprentice first, see if you can do it, and then formally enter the gate wall.

Qingfeng didn't dare to be negligent, and made a very careful selection, and chose six people to come back.Because he is not yet an official disciple, he does not have a Taoist name, and he is only called by his original name.Mingyue is very happy that she has a few more candidates as juniors.He is the youngest in the audience, and he is a junior in front of everyone.Now I finally want to be a senior brother again, how can I not show off my senior brother's style?It's a pity that these boys can't count well, so Mingyue always complains, saying that the people selected this time are too stupid.

Qingfeng didn't care about Mingyue's words at all.Not everyone can learn math from a Ph. D. in mathematics. If Mingyue is tossed about, it will be messed up.Danfang is the most important place, and the most important thing is calmness and intelligence.Careless, cunning and frivolous, I'm afraid it's not harming others or myself.

Naturally, the important task of teaching the boy also fell on him.There are too many things that need to be paid attention to in the alchemy room, even washing and rinsing the cups, each has its own particular attention.Qingfeng divided people into three groups to supervise each other and handle chores.There are also some simple and error-free operations and records, which are also assigned.In this way, the burden on him and Mingyue's shoulders was much lighter, and they could devote themselves to learning qi refining with their mentor.

Zhen Qiong doesn't care about these things. Isn't it to teach apprentices to bring in new apprentices?It's enough to be ordered by someone, but the great cause of refining qi is more important.

"I'm afraid there's something wrong..." Looking at the data of the past ten days, Zhen Qiong frowned so much that she could almost pinch a fly to death.He wanted to measure the proportion of inert gas in the atmosphere, but after several combustion experiments, the results were different!Although the difference is not very obvious, there are always discrepancies.It seems that in the burned carbon gas, besides the inert gas, there are some gases that cannot be sucked away by the lime water.

What is the reason for this?

After thinking for a long time, Zhen Qiong finally sighed: "Qingfeng, go borrow some rabbits from your uncle, and let's do another set of charcoal burning experiments."

This carbon gas is so intense that it can kill people.Since dead objects cannot be detected, we can only try with living objects.

Although he couldn't figure out what his mentor was thinking, Qingfeng quickly borrowed a few little rabbits to carry out the carbon gas experiment again.Zhen Qiong also turned over the records. The carbon selected this time was divided into two types: charcoal powder and charcoal block, which were burned in large glass covers.Wait until it burns out, throw the rabbit in and see how it reacts to the carbon gas.

It turned out that it was okay not to try, but after a try, several people were shocked.Although they are all fatal, the rabbits often die silently in the glass cover that has been burned with charcoal, without even struggling, and there are signs of incontinence.It didn't look like suffocation, but rather like poisoning.

"I'm afraid it's charcoal poisoning!" Qingfeng still has experience in this, and immediately said, "If you burn charcoal for warmth in winter, if you don't pay attention, you will die in the house. My disciples have heard that the body of this charcoal poisoning will turn red." , will be as soft as boneless.”

He came out of the sewer, so I don't know how many strange stories he has heard.

Zhen Qiong rubbed her chin, lost in thought.He already knew that the carbon gas was fierce, but it was also burning charcoal, so there shouldn't be such a big difference.After thinking for a while, he had a flash of inspiration and blurted out: "Yes, this is the sign of insufficient vitality!"

His small Taoism does not study Qi refining.But Master once said that the furnace must be thoroughly burned, and the blast must be in place.If the vitality is insufficient, harm will occur.

Before, he couldn't figure out what harm would be caused by lack of vitality.Now that the rabbit carcass is in front of you, don't you understand?And this kind of insufficient carbon gas will not be integrated into the lime water, no wonder there will be errors in the measurement.

"Pick some more charcoal!" Zhen Qiong immediately became interested.This is a great discovery. If carbon gas is generated, there will be a lack of vitality.Will it be the same when burning other things?Just like sulfur gas and carbon gas, what is the difference between low vitality and full vitality?If this is the case, the meaning of vitality to alchemy is very different. Maybe the things that are refined can be subdivided into one or two parts.

But these are not in a hurry, this low-element carbon gas, he still has to try it out.See what its nature is and how to eliminate it.Well, why don't you heat it up first...

"What did you say, the furnace in the main courtyard exploded? Did the temple master get hurt?!" Chi Liaozi was taken aback when he heard Daotong's report, and asked immediately.

"Slightly injured..."

Before the fairy tale was finished, Chi Liaozi got up and strode towards the main courtyard.

Alchemy fryer is not a rare thing.However, he knew that Zhen Qiong's alchemy was quite different from others.When this exploded, it was really big or small.For a genius of alchemy like Zhen Qiong, nothing can happen!

Arriving at the main courtyard, Chi Liaozi strode into the alchemy room, and immediately saw Zhen Qiong grinning and sitting on a stool wiping alcohol.Beside him, there were still people kneeling on the ground.

Frowning involuntarily, Chi Liaozi stepped forward and asked, "What's the matter? It's seriously hurt?"

"It's okay." Zhen Qiong put down the alcohol, raised her hand to let Qingfeng bandage him, and said, "Test the carbon gas, accidentally saw an open flame, and it exploded. Only a few glassware were damaged..."

Is that a glassware thing?Chi Liaozi couldn't hold back his anger: "But someone made a mistake?!"

The one kneeling on the ground was the newly recruited fire-burning boy. Could it be that their hands and feet were not good enough to cause trouble?

Zhen Qiong shook her head: "How can I blame them? They all did what I said, but I didn't expect the carbon gas to explode..."

Qingfeng, who was bandaging up his teacher, couldn't help but shed tears: "If the teacher didn't protect that kid, how could he be injured?"

When the glass dish filled with carbon gas exploded just now, no one reacted.Only Zhen Qiong was shocked, and threw the nearest Taoist boy holding a joss stick to the ground.Thanks to this, the blown glass did not hurt the front door.It's just that Zhen Qiong couldn't dodge it in time, and was pierced several times by the glass.

"It's an experiment, injury is inevitable. I was also careless, and I didn't expect the carbon gas to explode." Zhen Qiong didn't take a small injury to heart.But the deflagration of carbon gas made him quite afraid.This thing is actually similar to biogas, mixed with vitality, it will explode when it sees fire, no wonder it is called "cool".Fortunately, the dose was not much this time, and no catastrophe was caused.

After finishing speaking, he couldn't help but said to those kneeling beside him: "Stop kneeling, hurry up and tidy up. You guys should go see the doctor too."

Several Taoist boys turned pale and stood up tremblingly.The one who was rescued still had tears on his face, knelt on the ground and refused to get up.

Hearing this, Chi Liaozi said with a dark face: "Your qi refining seems more dangerous than alchemy. You should wear protective clothing in the future, and you have to wear it well! The most important thing is to protect yourself!"

Is a boy who burns fire worthy of such protection?That's a piece of glass, if the pulse is pierced, there is a risk of death!

Zhen Qiong nodded perfunctorily, and became excited again: "Brother, this carbon gas is very weird! If there is enough vitality when burning charcoal, and the carbon gas produced can be absorbed by lime water , become harmless. However, when the burn is not sufficient, the hazards will be great! Not only is it flammable, it will explode, and if it is inhaled, it will also become limp and weak, and the limbs will twitch. Water can't absorb it at all!"

Chi Liaozi was startled when he heard the words: "Isn't this charcoal poison?"

Those who make alchemy will inevitably encounter charcoal poison.Therefore, the past dynasties have taken precautions, nothing more than ventilating, and placing water basins...

"Wait, you said that this thing can't even be dissolved in lime water?" Chi Liaozi suddenly woke up, "Then putting clean water in the room can't get rid of the charcoal poison?"

"Of course it can't be eliminated. If you want to get rid of the charcoal poison, you have to rely on ventilation, or use a chimney to direct the air." Zhen Qiong said bluntly.

Chi Liaozi hissed softly: "We should ask Qian Yi for this matter, and we should try it out."

It's the twelfth lunar month of winter, and it's the time to burn charcoal.Even a refiner like him thinks that water can detoxify charcoal, let alone an ordinary person.This matter can't be solved by just the two of them as alchemists, at least they need to find a medical student to figure it out thoroughly!Although Qian Yi is a pediatrician, he is also a doctor of Hanlin medicine.Whether it is looking for him or entrusting him to find someone from the imperial hospital, it is better than the two of them messing around.

Zhen Qiong did not expect this.All Taoist temples use heating channels, so two large kilns can naturally produce a lot of heating.The bedroom at home has also been remodeled, and it is connected to the stove, and the fire wall is built with Liuyi mud, so there is no place for the charcoal basin.

But after hearing what Chi Liaozi said, he also reacted, and nodded again and again: "Senior brother is right, you have to find Brother Qian quickly!"

Unexpectedly, before Qian Yi arrived, Han Miao had already rushed to Baoying Temple: "Why did the furnace blow up? Did you get hurt?"

Regardless of Zhen Qiong's struggle, he checked up and down, and then he seemed to collapse, and hugged her in his arms.Although Zhen Qiong would say "know how to fry" from time to time, it was the first time for such a long time of alchemy to fry the furnace.Hearing the news, he was so frightened that he put down his business and came directly on horseback.Fortunately, it's just a small injury...

Being embraced by someone, I could faintly feel the trembling coming from Han Miao's body.Zhen Qiong was very guilty, and quickly stroked his back comfortingly: "Brother Miao is not afraid, I will wear protective clothing when I practice Qi in the future. I will never get hurt again!"

At this moment, Han Miao didn't care about any protective clothing, he just wanted to drag him home and never let him make alchemy again.Taking two deep breaths, Han Miao said in a deep voice, "Didn't you mean refining Qi? Why is it so dangerous?"

Zhen Qiong gave a dry cough, but it was actually not very dangerous, it was because he tried to heat up the low-element carbon gas during the experiment that the disaster happened.But it’s hard to explain it clearly, so he hurriedly said, “I’m also here to study carbon gas. This time it’s really achieved results, and I know the principle of charcoal poisoning.”

Han Miao was stunned: "What's the reason for charcoal poisoning? Didn't you just get bored?"

"It's really stuffy. It's just that the charcoal fire is not burning enough, so it's easier to produce charcoal poison. I have asked Brother Qian to study it. Oh, yes, I heard from my brother that there are still many people who use water to decompose Carbon gas, it’s useless, it needs to be ventilated.” Zhen Qiong poured out all of what she had heard.

Han Miao's expression became serious, and he asked, "Does the window have to be opened for ventilation?"

Whether it is a brazier or a candlestick, there are styles of smoking through water, and it is also the most commonly used by rich people.Unexpectedly, this method could not prevent charcoal poisoning.What's more terrible is that glass windows are in fashion nowadays, if glass windows are installed, it may be difficult to even breathe.Once stuffed with carbon gas, wouldn't it kill people?

Zhen Qiong nodded again and again: "We need to open the window, or change the brazier, build a chimney, and let the smoke out of the house. But it's better to turn off the fire at night, and don't put the charcoal basin in the bedroom."

"This matter should be published in the newspaper as soon as possible!" Han Miao thought more than that simple, and immediately said decisively.

Such a major event must be told to the world, so as not to cause disaster!

The author has something to say: carbon monoxide is insoluble in water, not to mention heating, everyone should pay attention to ventilation when eating charcoal hot pot.

In ancient times, there was understanding of gas poisoning, but there were few records. It is estimated that the room sealing measures were not in place, and the probability of death from poisoning was not high.But if you change the glass window, it will kill you.
