In the middle of the courtyard of the Shaoxi Mansion Shipyard, a bamboo pole nearly three zhang high was erected, on which was hung the military flag of the Shaoxi Mansion Naval Army. Pen "Fun" Pavilion www.biquge.info

It was nearly noon, a man and a woman, two carrier pigeon soldiers wearing white shirts and backs, walking around in the yard, anxiously looking at the northeast sky, and muttering: "It's been so many days, it should have arrived, why is there no news yet?" ”

After Li Xiang got up early this morning and had breakfast, he and Zhao Er hid in a room, took a large copper bowl found by the owner, and put it on the small charcoal stove for heating to boil water.

Zhao Er sat on the small bench by the fire, put his hands on his cheeks, and asked in a very fluent voice: "My lord, why did we break this thing called 'alum' into powder and put it in the water yesterday, and now we are boiling the alum that has been soaked in half and has not yet dissolved all of it together with the water?" ”

"Stupid Zhao Er," Li Xiang tapped his head lightly, and said angrily: "Didn't I already tell you, to dissolve the alum, I want to make a medicine to cure the disease." Oh, it's the medicine that cures the old technician of this shipyard, Lao Peng's stomachache. On the day we first arrived, didn't you also see that he was so painful that he couldn't even stretch his waist to work for us. Do you still ask me to give him a little healing of the elixir, and forget about it so quickly? Therefore, I want to try to see if I can make medicine for him to cure his illness in the past two days, which can be regarded as a little bit of affection for him. ”

Zhao Er muttered: "Where is my Zhao Er stupid, you yourself often say to people that I am clever and smart." It's what you say and do that people don't understand. Can you use this 'alum' to soak in water to make a medicine for stomach pain, then just give him this 'alum' to eat directly, and it will make it so troublesome. ”

Li Xiang scolded: "Ho! Say you're stupid, you're still not satisfied, you'll forget it after talking about it a few times, and you won't use your brain to think about it if you haven't forgotten. Didn't we learn from books together from beginning to end......"

Zhao Er: "That 'Book of Heaven' can only be understood by you, and even Lord Wang can't understand it, what's the use of reading it with you?" ”

Li Xiang: "Bah! You dare to say such a thing, I read it while reading it, and I explain it to you at the same time, didn't you listen? I won't tell you so much, let's boil it and see if it can all dissolve it all right away. ”

After a while, the water in the copper bowl bubbled, and the alum inside slowly dissolved, and after all the alum melted, Li Xiang took the copper bowl to the ground with a cloth pad, and said to Zhao Er: "Don't touch it, after it's cold, you will know that it can't be made into medicine, I'll go sleep for a while." ”

"Benefactor...... Oh no...... It's broken, and it's like it's not broken again. Zhao Er rushed into the room in a panic, pulled up the dazed Li Xiang, grabbed the coat next to the bed and threw it at him, and roared urgently: "Lazy worm, isn't your ass itchy, go and see the things in the copper bowl, those missing alum have changed back to their original appearance in the bowl." ”

Li Xiang: "Hey, how can you use the words to scold me, it's not like words, it's too unlike." ”

Looking at the sun shining in from the window, it was only the beginning of the day at most, and I felt a little annoyed in my heart, and shouted: "What is it called, I just fell asleep and came to call, so noisy that people don't feel at ease when they take time to sleep." ”

"It's not like I'm arguing with you, it's ...... It's in that bowl...... Alum in a bowl...... Alum has changed back to his old ways......" Zhao Er was a little nervous, and his words were no longer so fluent.

Seeing the alum crystallized in the copper bowl on the ground, Li Xiang understood the reason after a little thought: there was too little water and too much alum, so after the heated supersaturated solution was cooled, the undissolved alum crystallized back to its original state, which was not strange.

In order to avenge the dissatisfaction of not sleeping enough, Li Xiang raised his face and asked Zhao Er: "Okay, it must be you who made a good bowl of medicine." Say, what exactly did you do with this bowl of water? ”

Zhao Er retreated aggrievedly, and whispered in his mouth: "I'm also kind, I want it to cool down quickly, so I blew on it, where do I think that even a few breaths will be bad." ”

Li Xiang took another porcelain bowl, poured all the alum and water in the copper bowl into the porcelain bowl, and then poured the water into the copper bowl and put it on the stove, and said with a calm face: "Hold it and can't pour it, if it can't be boiled now, only you ask." ”

Walked to the table and sat down, grabbed the tea bowl and took a sip of tea and rinsed his mouth.

Zhao Er stared at the boiling water in the copper bowl with blank eyes, and kept thinking about what "only you ask" meant.

The water in the copper bowl became less and less, and slowly the clear water turned milky white, and then some white powder appeared underneath. Zhao Er hurriedly shouted: "Come and see, I didn't move this time, and the water in the bowl turned white." ”

Looking up, Li Xiang sat on the chair and didn't move, and after a while, Zhao Er shouted in a fuss: "Ah, there is a lot of powder in the water in the bowl...... Hehe, if you add 'alum' to the same state now, then it's none of my business, it's your own ghost." ”

Li Xiang hurriedly took the cloth pad, took the copper bowl to the ground and examined it carefully, forcibly held back the joy in his heart, pretended to be a very serious look, just like facing countless cheering crowds, and said solemnly to Zhao Er word by word: "Now, I declare ......"

The voice dragged on for a long time, and it was a long time before saying what was to be announced. Zhao Er was so anxious that he stood by squatting, then jumping from standing, and finally couldn't help the curiosity in his heart, stood on the small bench and knocked Li Xiang hard, and shouted: "Do you want to kill me in a hurry, so that you are not so good, after hitting a few bags, see if you are in pain." ”

"Ouch!" Li Xiang screamed exaggeratedly: "Just tell you, do you have to be so heavy." ”

Zhao Er threatened: "Say it quickly, do you want to come again?" ”

Li Xiang dodged a step: "I'm afraid that you're not good, let me tell you that our medicine is made, and it's these powders." ”

"The powder in this copper bowl can cure Old Man Peng's illness?" Zhao Er asked suspiciously, looking disbelieving.

"Of course," Li Xiang said triumphantly, "you also know that your family is an adult, but you are an omnipotent person." ”

Zhao Er: "So, 'omnipotent adult', tell me what is going on with Old Man Peng's stomach pain, why can it be cured by using this kind of alum soaked in water, but not directly using alum to cure him?" ”

Li Xiang was stunned by Zhao Er's question, this question is not easy to answer, and it has to take half a day to talk about it. He pretended not to hear and put the copper bowl back on the stove, so that all the water in the bowl was not completely dry would evaporate.

As soon as Li Xiang returned to the shipyard that day, he saw the painful appearance of the old man Peng who came to pick him up, and after a little inquiry, he understood that the old man had stomach pain or stomach ulcers and other diseases. Li Xiang, who has a super 3D printer, knows very well that this disease can immediately relieve pain as long as a few cheap tablets of "stomach Shuping" are used. He also understood that gastropin was a medicine that could be made with an easily available material, but there were no such materials here. (To be continued.) )
