Zhu Niang just came to see her son, and when she saw that it was okay, she stayed with Tang Yin again, so she put her mind at ease and told her son to study hard and leave after staying for less than half an hour.

Zhu Hao said: "Mother, I'll go with you to have a look." ”

Zhu Niang didn't want her son to go to the market town, her plan was to see how the disease progressed in the next two days, and if she couldn't, she would take Zhu Ting to Anlu City to find a doctor to see a doctor, in her opinion, only a doctor in the city could treat this disease, but Zhu Hao knew in his heart that the level of doctors in and out of the city was about the same, and it was more about physical resistance to get sick.

When he went to the market town this time, in addition to checking Zhu Ting's condition, he also wanted to buy some materials and come back, ready to help his sister tide over the difficulties in his way.

"Is Mr. Lu going with you?"

Before Zhu Hao left, he looked at Tang Yin.

Tang Yin thought about it, if it was a few days ago, he would definitely not stay in the village alone, but now that he is familiar with the villagers, he finds that these people really have no ill will towards him, and he was completely too cautious and cautious before, so much so that he thought too much.

Now that there is an epidemic outside, it is better to go out and walk around less.

Tang Yin waved his hand: "Go early and return early." ”

Meaning not to go.

……

……

The village is actually not remote, and the transportation is convenient, less than ten miles from the nearby market town.

When he arrived in the town, Zhu Hao told Zhu Niang some basic knowledge about disease prevention.

The most important thing is to keep it well ventilated and make a mask with a thick cloth to cover your mouth and nose.

When I entered the rented courtyard and saw Aunt Li and Zhu Ting, the situation was not very good.

As an adult, Aunt Li's physical fitness is not bad, and her condition is relatively stable, but Zhu Ting's little face is pale, and she is having a high fever when she touches her forehead, although she has her eyes open, she doesn't look energetic, and when she sees Zhu Hao, she barely squeezes out a smile and shouts: "Brother." ”

Just this brother, Zhu Hao has a sense of mission.

He didn't go to the doctor, but went directly to the people Su Xigui left in the town to contact him.

It was an old shopkeeper about fifty years old under Su Xigui, surnamed Jin, who was very respectful to Zhu Hao: "Little master, you came to our host?" Our host left for Wuchang Mansion two days ago, and before leaving, he specially instructed that if you have anything to arrange, just ask...... The old decay is here, waiting for you to call at any time. ”

said that it was a call, that is, to leave a contact person, on the surface, it was to open a shop in the market town, wholesale and retail firewood, rice, oil and salt, in fact, it was convenient for Zhu Hao to suddenly think of some salt drying tricks, and inform him as soon as possible, and the contact person Pegasus sent a message to Wuchang Mansion to inform Huang Zhan, and then Huang Zhan notified the household department......

It's like a war.

But this time, Zhu Hao found Su Xigui's person and asked him to help him go into the city to order materials.

……

……

Night.

Zhu Hao did not stay in the market town, but returned to Shangkuo Village.

When he came back, he happened to find six or seven children in Xiakuo Village, ready to study with him, Xiakuo Village was much smaller than Shangkuo Village, and the people were not prosperous, and it took many days to find all the people.

Tang Yin looked at Zhu Hao and said, "I thought you wouldn't go back today." ”

Zhu Hao said: "Mr. Lu, I bought some herbs in the market town, but there are still a few medicines that are insufficient, and I am asking Su Dongzhu's people to go to Changshou County to help me buy them." ”

Tang Yin frowned, and wanted to say, you kid is quite good at calling people, if Su Xigui knows that the people he left behind will give you a hand to do chores, what do you make Su Xigui think?

"What are you going to do?" Tang Yin asked.

Zhu Hao was very anxious: "I told him, no matter how late it is today, I must send the materials I need, and those customized things are really inconvenient to transport, so they must be delivered tomorrow morning...... Fortunately, I was prepared a few days ago, if Mr. Lu is busy, please go and rest, forgive me for not being able to accompany him more. ”

Zhu Hao originally wanted Tang Yin to help him, but thinking of the crooked reasoning of a gentleman who cooks far away in this era, let alone doing handiwork, Tang Yin, an arrogant and talented man probably wouldn't do this.

Anyway, they are all novices, and letting those children help is actually pretty much the same, as long as they are taught, the children are sometimes more diligent and flexible.

……

……

What Zhu Hao wants to do now is a plant antibiotic that can be easily extracted in this era, roughly including Houttuynia cordata concentrate and berberine, and there is also a special Bupleurum injection for fever-reducing, which is probably the most effective treatment of influenza that Zhu Hao can think of at present.

However, in order to make these kinds of plant extracts, it is inevitable to use an industrial raw material that has never existed in this era, that is, sulfuric acid.

Fortunately, the traversal has summed up a set of relatively formed soil method to make sulfuric acid process, that is, the lead room method, the tools used need to be customized, and the problem is not big, but some raw materials are difficult to search on the market for a while, and they really need the help of businessmen with certain connections, which is why Zhu Hao used Su Xigui's subordinates.

The transformed ceramic cylinders and ceramic tube connectors that are needed at the moment are still being made and transported, so Zhu Hao can only grind the medicinal materials bought from the market town first.

It's relatively easy to have children to help.

Tang Yin didn't go back to rest, but stayed in the laboratory, watching a group of children busy there under a few bright candlesticks, there was an indescribable feeling, he wanted to go up and ask what he could do, but after thinking about it, he still sat aside, pretending to be a book, in fact, he had been paying attention to what Zhu Hao was doing.

In the second half of the night, there was a commotion outside, but it was the golden shopkeeper under Su Xigui who came with the necessary materials and pottery masters.

"Young Master Zhu, the things you want are too expensive, and they are easy to damage when bumped on the road, some of them are brought directly in the city, and some of them are brought to the site for firing according to your instructions...... Let the master repair it for you! ”

The gold shopkeeper is very enthusiastic.

As Su Xigui's right-hand man, he is actually semi-retired now, and he is also a person who rarely knows that Zhu Hao has been of great help to Huang Zhan's career, and Su Xigui can't let him settle down in this small place if he doesn't tell him the truth.

Since he knew what Zhu Hao meant to Huang Zan and Su Xigui, he didn't dare to slack off when he did things, and Zhu Hao didn't say what the pottery master he found was for, if it was related to salt?

Zhu Hao said: "Trouble the gold shopkeeper, I may be busy until dawn, if the gold shopkeeper has other things, you can go back first...... Let the masters work overnight, I won't be disadvantaged here, it's okay to pay three times more than usual, right? ”

The golden shopkeeper had no intention of going back, and he didn't want to leave after hearing this.

Even if it is not related to the drying of salt, I have to know what Ling is doing, so that I will not be considered idle if I stay in Anlu, otherwise the group of colleagues around Su Dongzhu still don't think that my Lao Jin is an incompetent straw bale?

……

……

The yard was busy.

Ceramic cylinder, the large tank every two for a group, one up and one down, mouth to mouth up, and then with the bowl mouth thick clay ceramic conduit, the docked large tank is connected, with the pottery master firing the joint, forming a closed space, it becomes a distillation tower composed of five groups of large vats.

The principle of using the lead chamber method to produce sulfuric acid and nitric acid is to produce sulfur dioxide gas after roasting, including pyrite, sulfur, smelting flue gas, hydrogen sulfide, gypsum and waste sulfuric acid, etc., into the lead chamber tower, and after complex chemical reactions, sulfuric acid liquid is formed and dripped out.

This is true in theory, but it is not easy to put it into practice.

First of all, the size of the ceramic cylinder is not very suitable, saying that the big can not form industrial production, saying that the small is for the temporary firing of sulfuric acid and cumbersome, so that in the firing connector to maintain the sealing, it took a lot of work, near the dawn, Zhu Hao found that the sealing of the soil glue is insufficient, before the gold shopkeeper bought back the gypsum is not very good, so let the gold shopkeeper take people back to Anlu again, as soon as possible to purchase a batch back.

It was nearly sixty miles back and forth, and even if the road was smooth, the carriage would take nearly three hours.

Fortunately, the golden shopkeeper rushed back with people and materials in time, and Zhu Hao prepared the necessary materials, even the bottles and cans used to refine plant antibiotics were also prepared and began to preheat, just waiting for the lead room for refining sulfuric acid to be completed.

After more than half an hour, the entire equipment of the lead chamber method was officially completed, but Zhu Hao was afraid that there would be any accidents halfway, such as where there was air leakage after heating...... Fortunately, the previous inspection was relatively perfect, and the four craftsmen found were highly skilled, so there were no accidents in this regard.

The golden shopkeeper saw Zhu Hao walking around in front of several ceramic jars, adding materials and checking the temperature of the furnace, and couldn't help but ask curiously: "Little shopkeeper, isn't this burning...... Salt bar? ”

The golden shopkeeper can see it, and what he is doing in front of him can't do anything with the eight poles of salt, but it seems to be ...... Burning salt?

But the question is......

Can salt be done by firing?

That's about the same as frying salt on firewood, right?

Zhu Hao turned a deaf ear to the question of the golden shopkeeper.

Busy with work, how can you have time to deal with so many curious babies?

Tang Yin next to him covered his nose to resist the pungent smell, but he was reluctant to leave, wanting to see what Zhu Hao was doing, and took the initiative to take over the conversation at this time: "Naturally, it is not to burn salt, it should be to prepare for the treatment of local epidemics." ”

"Huh?"

The golden shopkeeper looked confused, and hurriedly asked the famous Tang Yin, "Tang everyone, you are well-informed, can you tell me, what is the relationship between this great effort and the epidemic in Jianghuai and Jiangnan areas?" ”

Originally, Tang Yin didn't know, but after listening to the words of the golden shopkeeper, he realized that the scope of this plague was very widespread, because it was a respiratory infectious disease, coupled with the frequent population movement in Jianghuai and Jiangnan areas, this disease did not harm adults much, and only affected the old and weak with low immunity, so that the epidemic has been epidemic, and it has only recently spread to the Huguang area.

Tang Yin only roughly knew that Zhu Hao was busy with this overnight, and he had stayed up with Zhu Hao until now, but what Zhu Hao did was unknown.

Tang Yin waved his hand: "The smell here is too strong, why don't we go to the door and ask him later." ”

In these matters, Tang Yin is very real, I don't pretend to talk nonsense if I don't understand, if you want to know the answer, just ask Zhu Hao, anyway, I think the more this kid looks at it, the more evil it becomes.

I thought there was something superior behind him, but I haven't seen the shadow of a master until now, but this kid has made more and more decisions on his own, making people feel that everything is what this kid did...... So, let's watch him perform alone.
