Yan Liqiang walked around Huanglong County alone, but it only took more than an hour to ask two people, and he had already come to Chaoyang Lane in the county town and found the ice shop in the alley.

The name of this ice shop is called Chaoyang Ice Shop, in the middle of the alley, Yan Liqiang walked to the alley, and saw the signboard hanging outside the ice shop, and when he saw the signboard, Yan Liqiang walked over.

In his last life, Yan Liqiang thought for a while that eating popsicles in summer was the patent of modern people after the invention of the refrigerator, and it wasn't until he saw an auction of cultural relics on TV that one of the cultural relics was a box for ancient people to store ice, and he learned that the ancient Chinese, starting from the Tang Dynasty, could drink cold drinks and eat popsicles in the summer, and he suddenly found that he had no culture.

When saltpeter is dissolved in water, it will quickly absorb the heat in the water, so that the water becomes ice, and the ancients used this characteristic of saltpeter to make ice cubes - fill two large and small basins with water, put the small basin in the large basin, and then pour saltpeter into the large basin, and when the large basin freezes, the small basin is also frozen.

The same is true in this world, but those who can enjoy ice cubes in summer are rich families, so the ice shop for making ice is only available in economically prosperous counties or big cities, of course, there are also some local tyrants, who have an ice room at home to make ice, such as the Hong family in Liuhe Town, Yan Liqiang remembers that when he was young, every year when the weather was the hottest, Hong Tao, who was two years older than himself, came to the town school every afternoon with a popsicle with rock sugar。

It's summer now, almost two o'clock in the afternoon, cicadas are singing on a few old trees in the alley, the sun is poisonous overhead, and the ground is steaming, a few children are outside the ice shop, salivating and stretching out their heads to peep into the ice shop, and a guy in a blue guy's costume is standing at the door of the ice shop, like a scarecrow driving sparrows in the rice field, bombarding those children, "Go, go, don't block the door here, want to eat ice, ask for money for you Lao Tzu to ......"

When the guys blasted the children away, Yan Liqiang walked into the ice shop.

Unlike the outside, 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 chill hit him, which was extremely comfortable.

There is a counter in the store, and behind the counter are several freezers made of wood on the outside and tin on the inside.

A young man stood behind the counter, and after looking at Yan Liqiang twice, he felt that Yan Liqiang's age should not be like a little kid who came here to cheat and cheat, so a smile appeared on his face, "Does this guest want to buy ice, we welcome all kinds of ice here, pure ice, ice with rock sugar, and bayberry juice, all of them, and the price is fair, I don't know which one this guest wants?"

Hearing the ice with bayberry juice, Yan Liqiang felt that the saliva in his mouth came out all of a sudden, but unfortunately, he knew that the smallest of the ice sold in these ice shops was a large basin and a large basin, and it supplied the needs of a family, like the kind of popsicles that Hong Tao used to eat, only the big families themselves were willing to make them, and these small shops would not make ice cubes as small as popsicles at all, because the cost was high, not to mention, ordinary children could not afford it at all.

Yan Liqiang tried his best to show a pure smile on his face before he opened his mouth to the guy, "Ahem, do you have saltpeter here?"

"What did you say?" the guy in the store looked surprised.

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

"We only sell ice here, not saltpeter!" The smile on the guy's face narrowed up little by little, if it weren't for the smile on Yan Liqiang's face, I'm afraid Yan Liqiang would have been blasted out a long time ago.

"I know, I'll buy a little, I don't know if it's convenient!"

The guy shook his head resolutely, "We don't sell saltpeter here, you better go to other places to take a look, and besides, if the shopkeeper is not there, I can't be the master......"

"Do you know where saltpeter is sold?"

"I don't know!"

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

Looking at the guy's face, Yan Liqiang knew that the deal was not negotiable, so he touched his nose and walked out of the store by himself.

......

For the next few hours, Yan Liqiang was wandering around the county seat of Huanglong County, and he didn't expect that it would be so difficult to buy a little saltpeter.

He has been to three ice shops, but none of them are willing to sell saltpeter to him, which makes Yan Liqiang almost crazy, things like saltpeter are used very narrowly, and in the entire county, except for the ice shop, he doesn't know where there is such a thing as saltpeter.

But fortunately, Yan Liqiang's communication skills are very strong, since saltpeter can't be bought in the shop, but he finally learned from the mouth of a clerk in an ice shop that there is a supply of saltpeter in a trading house in Shiqiao Town, a major trading town outside Huanglong County.

Yan Liqiang patted his head, and then remembered that saltpeter could not only be used to make ice, but also to tann leather, and that the trading house in Shiqiao Town not only collected leather, but also supplied some raw materials for tanning leather, such as lime and saltpeter.

......

By the time Yan Liqiang walked out of the trading house in Shiqiao Town, it was already nearly evening, and the sun was almost setting.

The saltpeter in the firm is supplying customers in large quantities, and those customers are often tens of kilograms, hundreds of kilograms when they buy it, just when he went in and said that he wanted to buy a pound of saltpeter, he was almost driven out by the guys in the firm, people thought he was going to amuse people, and finally, Yan Liqiang took out the silver, and the guys in the firm sold him a little bit in disbelief, but the price, relative to saltpeter, is "sky-high", two dollars of silver, and finally only bought a catty.

Yan Liqiang, who walked out of the trading house, touched the few taels of saltpeter in his arms, and let out a long breath, this time he only bought a little and went back to see if he could make gunpowder, if he could, he would naturally have a way to get saltpeter in the future.

Looking up at the sky, it was not early, and if it was too late to return to the craftsman camp, it would not be good for Qian Su to worry.

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

Shiqiao Town is a big commercial town, there are a lot of merchants from the south to the north, the square in the center of the town is surrounded by shops and restaurants, and there are many people who directly set up stalls on the side of the square, selling some herbs, miscellaneous and other things, and renting a carriage is also 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 rhinosaurus horses rushing to the square hill from a distance like the wind, and the four riders on the rhinosaurus horse jumped off the horse, and one of them picked up a gong from the saddle and quickly struck it.

In my previous life, I went to a forum on the Internet, and if I wanted my speech to be watched and disseminated, then put the post at the top, or let the big V or something like that, and in this world, there is no Internet, and there is no forum, I heard that there are newspapers in some big cities, but Yan Liqiang has not seen it, in addition to the government can post various notices, ordinary people, if they want to speak out in public and attract the attention of others, hitting the gong in a crowded place is the fastest way.

Sure enough, in the blink of an eye, a large number of people gathered around the four riders who came to the square on rhinosaurus horses.

Because it was the matter of the voice around him, Yan Liqiang also crowded into the crowd with the intention of watching the excitement, wanting to see what these two people were going to do.

The four riders, one of whom was older, and the other three were all young, the older one, judging by the clothes on his body, seemed to be the steward of a large family, while the younger three riders seemed to be the nurses and the like.

At this time, both the older steward and the three younger ones were sweating profusely and looking anxious, the younger three housekeepers were better, and the older steward was panting and pale.

"Isn't that person the steward of the Lu family, what is this for?"

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

The Lu family, Yan Liqiang didn't seem to have heard faintly before he came to Huanglong County, there is a big family in Huanglong County that has been inherited for hundreds of years is the Lu family, but Yan Liqiang doesn't know if the Lu family that the people around him are talking about is the Lu family he heard about, after all, there is more than one big family surnamed Lu in Huanglong County.

Seeing that hundreds of people were gathered around in an instant, and they were already in a circle, the steward took a few breaths, calmed down, and as soon as he raised his hand, the man who was beating the gong stopped suddenly.

Lu Guan hugged his fists around in advance, looked around, and then said loudly, "Fellow villagers, friends, I am the manager of Lujiazhuang in Lianhua Mountain, called Lu Wenbin, some friends may know me, today I came here, I want to ask for an urgent matter, I don't know if there is a secret recipe for treating people who are drowning among the villagers and friends, there is a child in Lianhua Villa who is drowning today, and I am here to ask for help!"

Steward Lu looked at the crowd of onlookers with hopeful eyes, but the crowd of onlookers was silent for a while, everyone was a little inexplicable, Yan Liqiang also wondered in his heart, someone in the Lu family was drowning, and he actually came here to find someone to help, which is too strange.

"Steward Lu, there is a child drowning in Lujiazhuang, you should hurry up to find a doctor, the Lu family is so rich, what kind of doctor can't be found, why did you come here?"

Steward Lu was silent for a few seconds, and then said in an astringent voice, "The doctor has been found, the best doctors in Huanglong County and Pingxi City are already in Lujiazhuang, but it has been three or four hours since the child drowned, and several doctors are helpless, there is no way, so I came to ask you for help from your hometown friends, to see if you have a secret recipe to try, if you can save people, the Lu family will be grateful, even if you can't save it, the Lu family will not blame ......"

As soon as the people around heard it, they immediately understood, the best doctor in Huanglong County and the county town Lu family was invited, but they didn't save people, this Lu steward said that three or four hours had passed, which meant that the drowning child had been silent for three or four hours, twelve hours a day, three or four hours had already passed for half a day, people died so much that they couldn't die anymore, and there was no way for the Lu family to invite the best doctor, who could have anything to do?

After all, this resurrection technique is just a legend, and how can a child who was drowned in the water be rescued after such a long time? It is estimated that the Lu family is also a dead horse as a live horse doctor, there is no hope, and there is no other way, so the steward will come outside with the slightest possibility to give it a try.

The people around listened to it, shook their heads directly and dispersed, the Lu family's heavy thanks were naturally coveted, but without the ability to bring the dead back to life, it would be a waste of time to go, and if you don't have the ability to fool around, you might get into trouble.

The people who dispersed were talking in a whisper, speculating that they didn't know which child of the Lu family was drowned, which would make the Lu family so nervous.

Seeing the people around him disperse, the Lu family steward's eyes showed a look of despair and despair, and he lowered his head helplessly......

At this moment, Yan Liqiang groaned slightly, and walked directly in front of the Lu family's steward, and said calmly, "Lu's steward, I may be able to try......"

Hearing Yan Liqiang's voice, Steward Lu raised his head suddenly, and when he saw that the person standing in front of him was just a fourteen or fifteen-year-old boy dressed ordinarily, the surprised expression on his face froze......
