Yan Liqiang walked and walked around Huanglong County alone. After only taking more than an hour, he asked two people, and then he had already arrived at Chaoyang Lane in the county town and found the ice shop in the alley.

The name of this ice shop is Chaoyang Ice Shop. In the middle of the alley, Yan Liqiang walked to the entrance of the alley and saw the sign hanging outside the ice shop. Seeing the sign, Yan Liqiang walked over.

In his previous life, Yan Liqiang thought that eating popsicles in summer was a patent of modern people after inventing the refrigerator. It was not until he saw an auction of cultural relics on TV that one of them was a box that ancient people stored ice. He heard the host's introduction that he realized that the ancient Chinese could drink cold drinks and eat popsicles in summer since the Tang Dynasty, and he suddenly realized that he was not educated.

In ancient times, people used ice to make ice instead of refrigerators, but saltpeter. When saltpeter dissolved in water, it would quickly absorb the heat in the water and turn water into ice. The ancients used this characteristic of saltpeter to make ice cubes - filled two large and small basins with water, placed small basins in large basins, and then poured saltpeter into the large basins. When the large basins freeze, the small basins would also freeze.

The same is true in this world. But those who can enjoy ice in summer are rich families, so ice shops that make ice are only available in economically prosperous counties or big cities. Of course, there are also some local tyrants who have ice rooms at home to make ice. For example, the Hong family in Liuhe Town, Yan Liqiang remembers that when he was still young, when the weather was the hottest days of every year, Hong Tao, who was two years older than him, came to the town school with a popsicle with rock candy every afternoon. That kind of majesty was like a local tyrant driving a Rolls-Royce to the countryside, which still makes him remember it fresh.

It's summer now. It's almost two o'clock in the afternoon. The cicadas were chirping on several old trees in the alley, the sun was poisoning, and the ground was steaming. A few children were outside the ice shop, snoring their heads and stretching their heads to peek into the ice shop. A guy in the ice shop dressed in blue guys was standing at the door of the ice shop, like a scarecrow driving sparrows in the rice fields, blasting the children, "Go and go, don't block the door here, want to eat ice, ask for money for you..."

When the guy knocked those kids away, Yan Liqiang walked into the ice shop.

What's different from outside is that as soon as he entered the ice shop, Yan Liqiang felt that the temperature in the ice shop was several degrees lower than outside, and a coolness came, which was extremely comfortable.

There is a counter in the store, and behind the counter are several freezers with wood on the outside and tin-layered inside.

A man stood behind the counter. After looking at Yan Liqiang's eyes, he felt that Yan Liqiang's age should not be like a little kid who came here to cheat and drink. He only showed a smile on his face, "Does this customer want to buy ice? We welcome all kinds of ice, pure ice, ice with rock sugar, and bayberry juice with it. There are all kinds of ice, and the prices are fair. I wonder which one this customer wants?"

When Yan Liqiang heard that there was ice with bayberry juice, he felt that saliva in his mouth suddenly popped up. Unfortunately, he knew that the smallest ice sold in these ice shops were all large and large. They supply the demand of each household. Like the popsicles that Hong Tao used to eat, only wealthy families were willing to make. These small shops would not make ice cubes as small as popsicles, because the cost was high, and ordinary children could not afford it.

Yan Liqiang tried his best to show a pure smile on his face, and then spoke to the mate, "Ahem, do you have saltpeter here?"

"What did you say?" The shop guy looked surprised.

"I mean saltpeter, saltpeter for ice making, I want to buy some!"

"We only sell ice here, not saltpeter!" The smile on the guy's face gradually restrained. If it weren't for the smile on Yan Liqiang's face, he would have blown Yan Liqiang out long ago.

"I know, I'll buy some, I don't know if it can be convenient!"

The guy shook his head firmly, "We don't sell saltpeter here, you'd better go to another place to check it out. Besides, the shopkeeper is not here, I can't make the decision..."

"Do you know where to sell saltpeter?"

"I don't know either!"

As he was talking, a guest came in, and the guy ignored Yan Liqiang and went to greet the new guest.

Looking at the guy's face, Yan Liqiang knew that the deal would probably not be settled. He touched his nose and walked out of the store by himself.

...

For the next few hours, Yan Liqiang was wandering around the county town of Huanglong County. He didn't expect that it would be so difficult to buy some saltpeter.

He has been to all three ice shops, but none of them is willing to sell saltpeter to him, which almost made Yan Liqiang crazy. Things like saltpeter have very narrow uses. In the entire county, except for ice shops, he didn't know where there were saltpeter.

Fortunately, Yan Liqiang has very strong communication skills. Since he can't buy it in a saltpeter shop, he finally learned from a clerk in an ice shop that purchased fur goods in a shop in Shiqiao Town, a large commercial town outside Huanglong County.

Yan Liqiang patted his head and then remembered that in addition to making ice, saltpeter was also used to tannate leather. The shop in Shiqiao Town not only collected leather, but also supplied some raw materials for tanning leather, such as lime and saltpeter.

...

When Yan Liqiang walked out of the business in Shiqiao Town, it was almost evening and the sun was about to set.

The saltpeter in the business is supplying a large number of customers. When they buy it, they often cost dozens of kilograms or hundreds of kilograms. When he just went in and said he wanted to buy a kilogram of saltpeter, he was almost driven out by the shopkeeper in the business. People thought he was going to play with it. In the end, Yan Liqiang took out the money, and the shopkeeper in the business sold it to him half-believingly, but the price, compared to saltpeter, was a "sky-high price", two cents of silver, and in the end he only bought one kilogram.

Yan Liqiang, who walked out of the business, touched the saltpeter in his arms and let out a long breath. This time he only bought a little and tried to make it out of gunpowder. If it could do it, he would naturally have a way to get saltpeter in the future.

I looked up and looked at the sky. It was getting late. If I returned to the craftsmanship camp too late, it would be bad to worry Qian Su.

Thinking of this, Yan Liqiang walked towards the square in the town center not far away.

Shiqiao Town is a large commercial town with many merchants from south to north. The square in the center of the town is surrounded by shops and restaurants. There are also many people setting up street stalls next to the square, selling some herbs, muddy and other things. If you rent a cart, you will also be in the square.

Yan Liqiang had just walked to the edge of the square and was about to call the carriage when he saw the four horse-ridden horses rushing to the square mountain from a distance like the wind. The four riders on the ring of the horse jumped off the horse's back, and one of them picked up a gong from the saddle and started to beat it quickly.

In my previous life, I went online forums and wanted to be watched and spread, so I would put the posts on top or let the big Vs forward them. There is no Internet or forum in this world. I heard that there are newspapers in some big cities, but Yan Liqiang has never seen them. In addition to the government's ability to post various notices, ordinary people want to speak out in public and attract others' attention, and ringing the gong in crowded places is the fastest way.

Sure enough, in the blink of an eye, the four riders riding the Rhino Dragon Horse came to the square gathered a large number of people around the square.

Because it was just a matter of speaking out around you, Yan Liqiang was thinking about watching the fun and was crowded among the crowd, wanting to see what these two people were going to do.

The four riders, one of them was older, and the other three were very young. The older ones looked like they were in charge of a wealthy family, while the younger three riders seemed to be servants of the hospital guards.

At this time, no matter whether the older manager or the three younger servants guards were sweating and anxious, the younger servants were better, and the older manager was panting and pale.

"Is that person not the Lu family's manager? What are you doing?"

A small businessman setting up a stall beside Yan Liqiang looked at the manager and said curiously to the person next to him, and was heard by Yan Liqiang.

The Lu family, before Yan Liqiang came to Huanglong County, it seemed that there was a big family in Huanglong County that had been passed down for hundreds of years, which was the Lu family. However, Yan Liqiang didn’t know if the Lu family that the people around him mentioned was the Lu family he heard of. After all, there are more than one wealthy family in Huanglong County with the surname Lu.

Seeing that hundreds of people were surrounded by the surroundings, the in charge of the businessman took a few breaths, calmed down, and raised his hand and the servant who beat the gong stopped suddenly.

Manager Lu clasped his fists at the surroundings in advance, looked around, and then spoke loudly, "Dear fellow villagers, friends, I am the manager of Lujiazhuang, Lianhuashan, named Lu Wenbin. Some friends may know me. I came here today to ask for something urgent. I don't know that among all the villagers, there are secret recipes for treating drowning people. There is a child drowned today in Lianhua Villa, so I'm here for help!"

Manager Lu looked at the crowd watching with hopeful eyes, but the crowd was silent for a while. Everyone was a little confused. Yan Liqiang was also confused. Someone in the Lu family drowned and actually came here to find someone to help. This is too strange.

"Manager Lu, a child drowned in Lujiazhuang, should I go and find a doctor as soon as possible. The Lu family is so rich, what kind of doctor can't be found? Why are you here?" Among the onlookers, someone immediately asked the doubts in everyone's hearts loudly.

Manager Lu was silent for a few seconds, and then spoke in a stern voice, "The doctor has been looking for it. The best doctors in Hepingxi City, Huanglong County are already in Lujiazhuang. It's just that three or four hours have passed since the child drowned. The doctors are helpless and have no choice. So I came to ask for help from all the friends in the village to see if you have any secret recipes. If you can save the person, the Lu family will definitely thank you very much. Even if you can't save it, the Lu family will not blame you..."

When the people around him heard this, they immediately understood that the Lu family, the best doctor in Huanglong County and the county town, had been invited, but they did not rescue him. Manager Lu said that three or four hours had passed, which meant that the drowning child had no sound. Three or four hours had passed in a day, and half a day had passed. People died so much that they could not die anymore. There was no way for the best doctors that the Lu family could hire. Who could have any other way?

After all, this technique of resurrection is just a legend. How could a child drowned in water be saved after such a long time? I guess the Lu family also treated him as a living horse. There was no hope and there was no other way, so they would let the manager come outside to try it out with a little chance.

When the people around him heard this, they shook their heads and dispersed. The Lu family's gratitude was naturally covetous, but without the ability to revive the dead, it would be a waste of time if they went there. If they didn't have the ability to do it, they might even get into trouble.

The dispersed people were talking in a low voice, guessing that they didn't know which child the Lu family drowned was, which would make the Lu family so nervous.

Seeing the people around him dispersed, the Lu family manager showed depressed and desperate expressions in his eyes, and he lowered his head helplessly...

At this moment, Yan Liqiang pondered slightly and walked directly to the manager of the Lu family and said calmly, "Manager Lu, I may be able to try..."

Hearing Yan Liqiang's voice, Manager Lu raised his head suddenly. When he saw that the only one who was standing in front of him was a 14 or 15-year-old boy in ordinary clothes, the surprised expression on his face frozen...
