When he first came here, Qian Heng also considered whether to use his knowledge to make money. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Qian Heng was originally a master who didn't have any big ideals, otherwise he wouldn't have chosen a major in Chinese veterinary medicine to study.

It's just that if you want to be forced into this predicament now, and if you want to make Aunt Li's family's life better, you can only help.

Qian Heng thought about it for a long time, there are many industries that can make money in this Great Song Dynasty, but the most suitable one in front of him is to make a coal stove.

At the end of the Song Dynasty, the use of coal was actually very popular, especially in Bianliang City, which was a large user of coal, so it was common for surrounding states and counties to use coal for heating.

However, in terms of the use of coal, the people of the Song Dynasty have not yet researched a particularly suitable furnace. This is also a breakthrough that Qian Heng said to help the Li family make money.

Qian Heng didn't think about letting the Li family and his wife do this business alone, but saving a stove was not something he should do as a sitting doctor, so the Li family and his wife became the best coolies.

Fortunately, Qian Heng still had some money in his hand, so he pondered it carefully, found a piece of straw paper, wrote down all the materials he needed with black charcoal, and took out dozens of dollars and handed it to Uncle Li, asking Uncle Li to prepare according to the above things as soon as possible.

Qian Heng thought that when he went back to the hospital, no one looked for him to see a doctor, so he simply stayed at Aunt Li'er's house, watching Aunt Li burn the kang up, and the house gradually became warmer.

At this time, Aunt Li also boiled out the millet that Qian Heng wanted, Qian Heng only fished out some millet, and stirred the rest, although the rice soup was a little thin, but it could be warmer when you drank it. A few people drank the rice soup with a few pickle sticks, and Qian Heng took the millet grains that were fished out and ran to the back room to see the situation of those little chicks.

The fire in the back room has warmed up, and the chicks, who were originally frozen and shrunk into a ball, have become a lot more active now, although they still look very weak, but the overall condition has improved a lot.

Qian Heng found a broken tile, put it on the bottom of the dustpan, and sprinkled the boiled millet grains on the tiles, and the chickens in the dustpan finally came to life, clustered together, gathered on the tiles, and pecked at the rice grains on the tiles.

Aunt Li on the side clicked her lips while watching.

"Tsk, this, Brother Heng, if you feed it like this, you might as well freeze this chicken to death!"

Qian Heng frowned, he knew what Aunt Li meant when she said this, usually people eat rice just to fill their stomachs, where can they afford to feed chickens with millet?

But Qian Heng didn't want to give up, this was his first time going to the doctor, although this time he came out to treat the chickens, but there must be a beginning and an end.

Qian Heng thought for a while, "Aunt Li, no matter what, you have to do what I said, you can't make any mistakes for me, as for the supply of this millet, I will let your family see the income in these two days, what do you say?" ”

Aunt Li didn't have much hope for Qian Heng to let her family see income, but Qian Heng could take out dozens of dollars for her man to go out to buy things, although she didn't know what Qian Heng wanted to do, she still had a glimmer of hope, so she had to nod, "I listen to you!" ”

River sand, yellow mud, and cement are all ready-made, and you can find them by digging directly into the ground, and what really costs you money is the charcoal powder bought back from the charcoal field. Uncle Li's efficiency is quite high, and in less than an hour, the chicken boy has just recovered, and Uncle Li brought back everything Qian Heng wanted.

At the beginning, Qian Heng wanted to go back to his residence to tinker with the coal stove.

However, seeing Aunt Li'er's bottomless strength now, and the temperature in Li's house, which is okay, decided to start tinkering here.

As soon as he entered the door, Qian Heng saw the ground in front of the house and threw this piece of discarded hemp rope.

Qian Heng took back the piece of hemp rope that was more than a foot long, crushed it thoroughly, and asked Uncle Li to scoop a basin of water and start to mix mud.

Mix river sand and yellow mud with water, and then knead the broken hemp rope into it, and pat it into a round barrel shape little by little, making a simple hearth.

Give the kneaded hearth mud to Aunt Li, "Aunt Li, you bake this thing in front of the stove, don't burn it directly, just dry it a little bit!" ”

After arranging Aunt Li'er's work, Qian Heng began to mix the cement and charcoal powder together, and simply blended them into briquettes. Thinking in his heart, he found another wooden stick and began to pierce his eyes on the briquettes that had not yet hardened.

Qian Heng also knew that this was not how the briquettes were made.

After thinking about it again and again, Qian Heng decided to go out by himself, found a blacksmith shop, and drew a sketch for the blacksmith of the mold for making honeycomb briquettes.

After breaking it down little by little and explaining to the blacksmith how to get it, Qian Heng paid the deposit and returned to the Li family with a few scraps of iron.

By the time Qian Heng returned to Li's house, the hearth tube that Aunt Li was baking had been basically fixed.

Qian Heng didn't expect this hand-rubbed hearth to last long, so he directly picked up the hearth tube, put it in the wooden barrel, and padded the scrap iron rod-like things brought back from the blacksmith shop at the bottom, and began to fill the gap between the hearth and the wooden barrel with river sand.

It wasn't until after filling up and smoothing the mouth of the barrel that Qian Heng picked out a few pieces of charcoal from the stove that were still formed and burned vigorously, and threw them into the hearth. I picked out a few more freshly made briquettes and covered them.

A puff of green smoke came out of the hearth, and after a crackling sound, the green smoke began to fade, and the briquettes thrown into it were also ignited by the charcoal below, and the temperature in the hearth rose significantly.

Seeing the birth of a simple briquette stove, Qian Heng felt a sense of accomplishment.

Looking at the coal fire that was gradually burning in the hearth, Aunt Li and Uncle Li glanced at each other and asked with a surprised expression, "Brother Heng, you can actually light this charcoal powder mixed with mud." ”

Qian Heng laughed.

"Uncle Li, Aunt Li, this thing is called a honeycomb coal stove, I went to the blacksmith shop to make a mold, and I have already said that I will pick it up the day after tomorrow, and when I go, you will let him beat an iron barrel skin, just like this wooden barrel!"

Qian Heng pointed to the wooden barrel, "This wooden barrel is easy to burn, so if you really want to use it, you have to use iron sheets, you have seen everything else, it's as simple as that, when the mold in the blacksmith shop comes out, I will teach you how to use it, now what you need to do is to go to various charcoal farms and collect these charcoal powders back, as long as Uncle Li can make this coal stove, just selling briquettes can earn enough money for the winter." ”

Aunt Li still looked disbelieving, "Brother Heng, can this thing make money?" ”

Qian Heng smiled, "Uncle Li, the price of this charcoal powder is not high, right?" ”

Uncle Li nodded, "With so much charcoal powder, I spent two pennies, and the rest are ready-made things, no money!" ”

"That's right, let's buy a few hundred pieces of charcoal powder, plus the cement mixed with these carbon powder, you can almost fill your yard, and the rest, you have to make this hearth pipe, the hemp rope or hair in it, it also costs some money, if you add this layer of iron sheet, a furnace down, it will cost dozens of dollars!"

"Uncle Li, don't do anything else in the past two days, first prepare the charcoal powder and cement for me, and I will come to check it tomorrow!"

When Qian Heng said this, he looked back at Aunt Li, "Don't stop the kang with fire, and you can't stop the millet that the chickens eat, I should have some money left over from Uncle Li, take it to buy some rice!" ”
