In the early morning of the second day, they had eaten the breakfast prepared by the eldest mother for them, and then set off for Hengchang County, when the eldest mother brought them some baked cakes, let them eat on the road, the two did not arrive in Hengchang until almost noon, Han Zimo led Gu Xiaohan all the way to the porcelain firing shop, and the shopkeeper Wang, who was responsible for taking care of the business in the store, saw the arrival of Han Zimo, and hurriedly greeted him and said: "The owner of the village is finally here." Didn't you leave early a few days ago, why did you arrive today? "Shopkeeper Wang, something happened on the way, and it was delayed for a few days. "What's wrong, are you okay?" "I'll talk about this later, you can take me to see the porcelain first." "Okay, please come with me." "By the way, this is Miss Gu, in the future, she will be responsible for taking care of what Siyan did before, please report anything to her when I am not there in the future." ""Miss Gu, the little one has seen Miss Gu." "The shopkeeper doesn't have to be polite, if Xiaohan doesn't understand anything in the future, please ask the shopkeeper of the king for advice." "The girl is polite, then you are also please." Inside, the shopkeeper led them to a room where the porcelains were stacked, and he said, "Look, owner, these porcelains were fired just a few days ago, but their color is not only jet black, but also very rough, but the method of making them is the same as before, and nothing has changed. "So, what do you find in the raw materials you make?" "The raw materials are also the same batch as the last firing, but there is no problem with the porcelain fired last time, it stands to reason that such a thing should not happen, you wait a minute." Before the shopkeeper Wang went out to the store again, he took a finished product that was being sold at the counter and showed them, Han Zimo took it and took a closer look, there was indeed no flaw, so he also felt very strange and said: "Since it is fired from the same batch of raw materials, why is this batch like this, you shouldn't have taken it out to sell, right?" "No, as soon as it was fired, I found a problem, so I asked the workers to put it away quickly, so as not to ruin the reputation of the store." "Okay, you did the right thing, find the problem as soon as possible and put it away in time, so it seems that people outside should not know that there is this batch of products." "So what now, where to start?" After listening to what they said, Gu Xiaohan said to Han Zimo: "Zimo, since you can't find the root of the problem for a while, then you should take a rest first, you have walked such a long way, and you are still injured, it is not good to be too tired." When the shopkeeper heard her say that Han Zimo was injured, he asked in surprise: "What happened to the owner, why were you injured?" Gu Xiaohan replied to him: "We just came out of the manor, and when we arrived at the Purple Bamboo Forest, we were chased by assassins and fell off the cliff, and he was bruised in order to save me, so we delayed the trip." "What, the Assassins are hunting you down, who are they?" "It's unclear who did it, but it should have something to do with the recent business incidents, and they probably wanted to take advantage of our outings to hunt us down." "Did they plan all of this in advance, but why did they do it?" "I don't know this yet, let's not talk about it yet, Shopkeeper Wang bothered you to take us to the guest room, let Zimo rest first." "Okay, you two come with me, owner." When he arrived in the room, Han Zimo said to him: "Don't spread out about me and Miss Gu coming here, the assassin should think that we have fallen to death and are not staring here, but just in case, it is better to be cautious." "Okay, don't worry, I know what to do." I'll go get you some food first, and you two will rest after eating. "Okay, you go." "Miss Gu, your room is next door." "Okay, thank you for the shopkeeper." After saying that, he went out to get food, and after a while he came in with food again, and Han Zimo asked him to go out first to do his work.

"Come on, Zimo eat quickly!" I'm tired of the day, and I'll talk about other things when I'm rested. Things will work out, don't worry. "Okay, so are you." "Hmm. After a while, they were ready, Gu Xiaohan took the dishes and chopsticks out, and asked the shopkeeper Wang to prepare two sets of clean clothes for them and send them to the room, and they were still wearing the clothes they wore when they went out.

After a while, the shopkeeper came with new clothes, and Gu Xiaohan said to him: "The owner of the village has an injury on his body, which is not very convenient, please go buy some medicine to treat abrasions and help him scrub and replace it." I couldn't help him with these things, so I went back to my room first. "Okay. Don't worry, girl, I'll have someone prepare water for her to freshen up, and you can rest well. "Okay, thank you, shopkeeper." Then they went about their work...... After Gu Xiaohan rested for a while, she didn't wake up Han Zimo and let him rest for a while, and then she came to the front desk to find Shopkeeper Wang and said, "Shopkeeper Wang, please take me to see the raw materials for making, I want to check if I can find a valuable place from it." "Okay, please come with me." When they came to the place where the raw materials were stacked, Gu Xiaohan asked, "Is there any leftover from last time?" "Yes, look at these over here. She took out the two kinds of raw materials that she had left over and had not done, put them to her nose and asked, her sense of smell was more sensitive, she could smell whether there were other impurities added to it, she still smelled a different smell from the two raw materials after smelling, and then said to him: "Please bring me some wine and essence, and take two clean plates and lamp oil, two pieces of gauze, and two funnels." "Okay, I'll go get ready." After a while, the shopkeeper brought what she wanted, she poured the wine and essence into the plate, put it on the lamp oil and smoked it to make alcohol, and then put the two raw materials into the plate and soaked for a while, put the soaked raw materials into the gauze and filtered through the funnel, and after a while different colors of alcohol flowed out from the two raw materials, and the shopkeeper Wang looked surprised and said, "Girl, what is going on?" "It seems that someone put a medium in the remaining raw materials that can make the porcelain black and rough, and I can't say what the specific medium is, so you let the workers make the porcelain from the unused and the leftover raw materials, and we will see if there is any difference between them." "Okay. Because it will take a certain amount of time to finish the porcelain, she will go back to Han Zimo's room first, and he will have already rested at this time.

After entering, she said to him, "Zimo, you are up, why does the wound still hurt?" "I slept with the medicine." It's so much better now, why don't you sleep more? "I've rested, so I went down and checked the ingredients, you go down and take a look, and I found a problem from inside." "Okay. When they came to the place where the experiment was done just now, Han Zimo saw the things placed on the site and asked her in surprise: "What kind of practice is this?" I've never seen it? "This is called physical analysis, and it is a method that detects the presence of impurities. "Physical inspection, what is physical inspection?" "It's a subject that our teachers taught us when we were in school, and we can find the answer through it." I smelled two ingredients, and I smelled a special smell from the leftover ingredients this time, but I didn't smell a strange smell from the leftover ingredients from the previous production, so I tried it this way, and I found it. "What, is it true?" What is this learning so magical. "As for what kind of knowledge, I explained that you don't understand, you come to smell and see what is mixed with it." He took it and sniffed it and said, "There is no such thing in my Zishu Country, I don't know where it came from. "Are you sure you haven't?" "Well, not really. "Then there is no way to verify. The two were talking, when the shopkeeper came to them with the freshly fired porcelain, and sure enough, two porcelain, one intact and the other inferior.

The shopkeeper Wang said: "Miss Gu is really good, she actually found the reason so quickly, and she used such a novel method, she admired and admired the little." ""The shopkeeper Wang, you have won the prize, this method is very common in our place, I just hope to find out the reason as soon as possible, find out the truth, and return the porcelain shop to a clean slate." Han Zimo heard her say: "The girl doesn't have to be too humble, the girl's knowledge really opened my eyes, I didn't expect such a novel method in this world." I wonder if the girl can teach this technique to the guys, so that they can also use this method to test the quality of the raw materials! "Okay. I'll pass it on to everyone later, don't worry. "Then it's a trouble girl." "Well, no trouble. After finding out what the problem was, Han Zimo was also relieved, and after a while, he asked the guys in the store to learn together......
