The last question is even sharper than the blade of the Cold Moon Knife, and the terrifying coldness makes everyone feel pain in their faces, especially Liu Can, who is facing the blade, and feels ten times worse.

Qin Yu, who was smiling calmly a moment ago, suddenly showed his edge like a sword out of its sheath at this moment, making everyone uncomfortable.

Long Mei'er was also very uncomfortable, because she was also dragged in, she felt that Qin Yu was borrowing her to attack Liu Can, although he and Liu Can were completely passers-by, but there was still a feeling of being used.

"You're just framing me at all!" Liu Can was finally forced by Qin Yu's momentum, and there was an imperceptible panic flash in his eyes, and he hurriedly turned around and hugged his fist towards Long Mei'er, "Miss Long, Qin Yu is simply unreasonable, please ignore his nonsense." ”

Du Ming immediately couldn't wait to shout: "Framed, this is framed, Sister Long, you must not ......"

Before she finished speaking, Long Mei'er suddenly turned her head, her momentum was like an angry dragon, and a cold light of disgust flashed in her eyes: "Shut up!"

Du Ming was immediately dumbfounded, covering his mouth and not daring to say a word again, his face turned red and embarrassed to the extreme, and Zuo Fan and a few people not far away slapped their legs and laughed without any scruples, unscrupulously mocking Du Ming for his death.

Long Mei'er turned her head to look at Qin Yu, frowned slightly, and said: "I did read an article on the Book of Food, but unfortunately the article is not clear and meaningless, if you want to prove yourself, just say why, otherwise, ......"

didn't finish speaking, but the meaning is self-evident, dare to play her dragon charm, the consequences are very serious, this precedent cannot be broken, otherwise her dragon charm majesty will not exist.

Liu Can said: "Yes, you said that coarse salt can't be eaten, and eating too much will lead to poisoning, so say why, if you can't say it, it's an insult to the big food family, and you will know the consequences." ”

He breathed a sigh of relief in his heart, he couldn't even say the specific reason for the article in the "Food Classic", how could Qin Yu know? But how did he know that Qin Yu happened to have an article about salt that was going to be submitted to "Shijing", and this article would also carry the names of the old courtyard master, Feng Jian Yuan, and Mr. Wang.

Everyone looked at Qin Yu, some were nervous, some were expecting, some sneered, framing the disciples of the Great Food Family, which was tantamount to contempt for the Great Food Family, and the consequences were really serious.

Qin Yu didn't panic, and said, "Okay, then I'll give you a make-up lesson, you wash your ears and listen." Mr. Wang, write down what I said, add it to the article and vote it to the "Food Classic". ”

The two words of the Food Sutra immediately caused an uproar, and Mr. Wang said: "Okay, you say, I remember." ”

"This starts with the composition of coarse salt, in fact, coarse salt is not an ingredient at all, but a mixture of many ingredients, some of which we need, some are harmful, coarse salt is refined into fine salt, is to remove the harmful part. ”

As he spoke, Qin Yu picked up a branch and scratched on the ground as he spoke: "My master has named these ingredients, among which the ingredients we need are called sodium chloride, and the unneeded ones are magnesium ions in magnesium chloride, calcium ions in calcium chloride, sulfate ions in sodium sulfate, and of course, there may be heavy metals such as barium, fluorine, arsenic, and lead, which are all hateful things that can harm health." ”

Looking at the strange symbols that Qin Yu drew on the ground, including Long Mei'er, everyone seemed to be reading the Book of Heaven, because Qin Yu habitually wrote NaCl, MgCl2, etc., and it was strange that people in the Food Continent could understand it.

What the hell is this? Liu Can was crazy in his heart, and Long Mei'er was also crazy in his heart.

After writing it, Qin Yu himself also realized the problem, isn't he playing the piano to the cow when he writes this?

Good question, like one.

Can you understand the answer? Nonsense, I can't understand it at all? I can't understand the answer? Isn't it admitting that I am ignorant? Someone came to drag my sister out and cut it down.

"Qin Yu, you bastard!" Long Mei'er clenched her fists in her heart, but she couldn't show anything on her face, majesty, and she couldn't forget majesty all the time.

Sure enough, Long Mei'er writhed a little embarrassed, her eyes didn't look at Qin Yu, and she said ambiguously: "It's okay, how can I not understand?"

Qin Yu laughed in his heart, Long Mei'er's embarrassing appearance of not knowing how to pretend to understand was really funny, which was completely different from the imposing appearance just now.

Liu Can almost wanted to scold, he was just about to say that Qin Yu was scribbling, but Long Mei'er came to this sentence, okay, Long Mei'er said that he could understand it, wouldn't he directly offend Long Mei'er if he depreciated it again?

"It's good to be able to read it, these are all symbols designed by Master to make it easier to remember, and contain most of the ingredients that may be present in coarse salt, of which these are harmful and must be removed by refining. Qin Yu used the branch to point at magnesium ions, calcium ions, and heavy metals.

Long Mei'er said: "What will happen if you don't remove it?"

Qin Yu said: "Let's take barium as an example, after eating barium chloride into the body, it will be distributed in the muscles, resulting in muscle poisoning symptoms, the facial limbs are numb with needles, muscle tremors, spasms, convulsions, respiratory paralysis, and cardiac arrest leading to death, which is a typical muscle poisoning symptom." ”

Mr. Wang was busy recording, and his heart was almost happy, this salt article has his name, although it is the fourth signature, but it is also a matter of glory to the ancestors.

After listening to Qin Yu's description, Mr. Wang suddenly thought of something, raised his head and said: "Wait, I remember, I heard that many years ago, there were many paralysis in some places, and it seemed to be related to coarse salt, and later the popularization of boiling salt refining technology put an end to this disease." ”

Hearing Mr. Wang say this, You Ju also clapped his hands and said: "Yes, I also remember, when I was a child, my father told me a story about this, and the only feeling I had at that time was that the paralysis was terrible." ”

Of course, Long Mei'er had also heard it, and said thoughtfully: "It seems that there is such a thing, but in fact, it was not completely certain at the time, and there is no completely reasonable explanation to this day, is it really because of the ingredients you said in the coarse salt?"

"Of course. Qin Yu nodded solemnly, saying that he was very sure.

Long Mei'er said again: "Can you prove it?"

Qin Yu smiled slightly, shrugged his shoulders and said, "What I said will soon be voted for the Food Classic, do you think I dare to say nonsense if there is no evidence?"

As soon as these words came out, the suspicion was completely shattered, no one dared to joke with the "Book of Food", since Qin Yu dared to contribute to the "Book of Food", there must be full evidence.

Long Mei'er no longer doubted, her face gradually turned cold, and the quail in front of her that was still full of fragrance was already unrecognizable, and the delicious quail in the soup seemed to be smiling at her, a terrible sneer.
