At the moment, he was silent, and in the super 3D printer, he was desperately looking for the entry of gastric comfort. When www.biquge.info accidentally saw the entry of aluminum hydroxide, he realized that Gastric Shuping was made of this kind of thing.

Although he now knew that gastric suppine was made from aluminum hydroxide gel after drying, he just didn't know what aluminum hydroxide gel was and how to make this aluminum hydroxide gel.

After thinking about it for a long time, I had to look at the aluminium hydroxide entry again with boredom, and found that the last sentence said that aluminium hydroxide was "made by the reaction of alum, aluminium sulfate or aluminium chloride with sodium hydroxide or sodium carbonate".

Aluminum sulfate, aluminum chloride? You don't have to think about it, aluminum sulfate has to have sulfuric acid first. If you have sulfuric acid, you can make many better things, and you can also make aluminum hydroxide!

Alum is ready-made, and it can be bought in large quantities in various pharmacies. As soon as you find out the entry of alum, aha, here it is said that it will hydrolyze when dissolved in water, and then form aluminum hydroxide gel. It's not simple, just let the alum dissolve in water and let it "solve".

In the evening of the same day, he broke the alum he had bought and soaked it in a bowl, thinking, "I don't know how long it will take for this alum to be 'hydrolyzed', but one night should be enough." ”

The next day, that is, today, when I got up, I saw that most of the half-catty broken alum in the bowl had not been dissolved, and the water was still so clear and transparent, and I didn't know if the water in the bowl had become a gel. I remember that I seemed to have read a chemistry book before, saying that the hydrolysis process of most substances is an endothermic process, and the "Chemical Dictionary" in the super 3D printer also mentions that the melting point of alum is 92 degrees. I decided to try heating the alum soaked in water right now, but if it didn't work, there would be no way. Anyway, I haven't told anyone about it, and it's not a shame that I can't make medicine for stomach pain.

Unexpectedly, this trial made him successful, and he really made aluminum hydroxide gel, and it dried into powder.

As for whether this powder is aluminum hydroxide gel powder or not, and whether it can be used to stop Old Man Peng's stomach pain, Li Xiang is still not sure. But he still invited Old Man Peng to come and let Old Peng decide for himself.

Old man Peng is actually not very old, and his actual age is only in his fifties. It's just that because of the bad stomach and the long-term torture of illness, people in their fifties seem to be seventy or eighty years old. Hearing that the adults were invited, he endured the pain in his stomach and came to see Li Xiang.

When Li Xiang told him about the matter, Old Man Peng immediately said with a smile on his face: "Eat, the old man is in pain like this, it is really uncomfortable, since this medicine will not be bad even if it can't stop the pain, why should I try it." ”

For the sake of insurance, Li Xiang didn't dare to let Old Man Peng eat too much at once, so he took a small piece of paper with about a piece of powder about the amount of stomach comfort, poured it into his mouth, and watched him wash it down with tea.

Less than half an hour later, Old Man Peng made a "uh" sound from his mouth, slowly exhaled a breath, closed his eyes and sat without moving. After a while, there was another "uh" sound, and the hand pressing on the abdomen gradually loosened, and a faint smile slowly appeared on his face.

As soon as Li Xiang heard that Old Man Peng had belched, he understood that this was a stomach disease, and people who took Gastric Shuping and effective would have a phenomenon after taking the medicine, and knew that this medicine had already worked on his stomach, but before Old Man Peng himself did not say the result, he was still not very sure how effective it was. I couldn't help but ask anxiously, "Mr. Peng, what do you think?" ”

"Well, it feels very good." Old man Peng stood up, moved his hands and feet, bowed to Li Xiang deeply, and his voice was full of joy: "In the past ten years, this stomach pain has made it impossible for my subordinates to do anything quickly, and this medicine is like an elixir...... No, like Xiansan, the stomach pain was cured in a moment, thank you young master! ”

Li Xiang: "Mr. Peng doesn't need to thank you, this medicine can only treat the symptoms, not the roots." To be honest, as far as I know, this disease has not been cured. Therefore, I am going to prepare more medicine powder for you, so that you can have medicine to relieve pain when you have a seizure in the future. That's fine, you go to the medicine shop in the city and buy more...... Well, I'll buy three or four catties of alum and come back, find a larger copper basin, and make more medicine for you to keep in store while there is no other news today. ”

Old man Peng was so happy that he almost knelt down to kowtow, but thinking that the young master didn't like this, he ran out of the door with a stack of "thank you".

Originally, Li Xiang had done a great deed, and he felt very happy in his heart, but thinking that Yuya had not had any news in the past five days, and he couldn't laugh if he wanted to, he couldn't help but feel restless in his heart: "Who will kidnap her, isn't the reward of 20,000 yuan enough to be tempting?" It shouldn't be possible, it must be that the person who kidnapped Jun Hui was hiding too secretly and didn't hear the news......"

From the afternoon to the evening of this day, because there was something to do to make medicine, it passed in the blink of an eye, and a total of three and a half catties of alum made about nine taels of white medicinal powder.

Li Xiang handed these medicinal powders to Old Man Peng, and explained to him: "Old Man Peng, this is a 500-serving amount of medicine, and it should be kept safe." I believe that you can use so many medicines for at least five months to half a year, and when you are almost exhausted, come back to me, and I will find a way to make more for you. ”

Old man Peng happily took a large bag of medicinal powder and said with a smile: "There is a fairy-like master like an adult under him, I really don't know how much incense I burned and how many kowtows I made in my previous life." This is good, at least half a year of peace and happiness is good. Adults are tired after a hard day, please rest in peace, and your subordinates will retire. ”

The next day was the fifth day of the twelfth month, and just when he was eating the breakfast carefully made by Old Man Peng, Zhao Er, who had extremely sharp ears, heard a few "cooing" sounds from the courtyard. He jumped up, dropped the rice bowl that had only eaten a few bites and rushed out of the dining room, and after a while, he walked to Li Xiang with a smile behind his back and a smile, and saw that the adult looked at him with a puzzled face, and proudly stretched out his hand, so that Li Xiang could see the small bamboo pipe he was holding and said, "How is it, do you want to see it?" ”

At this time, the two child soldiers chased into the hall, and saw that Zhao Er was using the way of a little urchin to make the adults happy, and they all wanted to see how the adults dealt with Zhao Er, so they didn't blame Zhao Er for robbing them of their own jobs.

Although Li Xiang was anxious to know what was written in the letter sent by the carrier pigeon just now, seeing that Zhao Er was using this method to tease himself, he still suppressed his desire and said lightly: "There is no need to look, you take it out and read it to me, let me see how many words our master taught you to know some time ago, and after reading it, write out all the words you recognize." Otherwise, you are not allowed to eat again today. ”

I only ate two or three bites of breakfast, and if I wasn't allowed to eat, wouldn't I be hungry for a whole day? Zhao Er couldn't help but be shocked when he thought that he hadn't had it for more than a year or two years, but it was a constant taste of hunger in the past. (To be continued.) )
