Otaku Engineer in Great Tang Dynasty

The black and heavy briquettes were placed in the raging charcoal fire. The originally very warm charcoal basin became less warm after being blocked by a part of the sparks!

"Xuan'er, there is no shortage of charcoal in our house, why are you coming over with so many briquettes? This thing is hard to burn!"

Li Jingmo frowned.

Although the briquettes picked up by Li Zexuan have a slightly different shape, coal is coal. In Li Jingmo's view, no matter what shape it is, there will be no charcoal to burn.

Li Zexuan smiled and said, "Father, it's true that our family can afford charcoal, but most of the people can't afford it! Your son is doing good deeds! Besides, this briquette is not just for baking, you see Ok!"

Seeing that his son was going to be stubborn to the end, Li Jingmo shook his head and stopped discouraging him.

But Mrs. Li's heart was so careful, she asked softly: "Xuan'er, your briquettes and stoves are designed for poor people? If that's the case, my mother will support you! Chang'an City doesn't know how many people will freeze to death every year, you This is a matter of immense merit!"

Women generally believe in cause and effect. Besides, since Li Zexuan was rescued by the real man Lingxu, Mrs. Li has become a loyal Taoist believer. At the end of the month, she will go to Xuanduguan to pray for the safety of her family!

"Xiaoxuan, grandma also supports you! As the saying goes, there are three good things in one day, and blessings will come in three years; there are three evils in one day, and disasters will come in three years! The Li family is now also a home of great wealth and nobility, only accumulating virtue Only by doing good can the wealth and honor last!"

Old lady Ye patted Li Zexuan's arm and smiled kindly.

The four generations of the Ye family practiced Taoism, and many Taoist teachings have been engraved in her heart under the influence of the old lady. She believes in the cycle of cause and effect more than Mrs. Li!

"Oh! Thank you mother! Thank you grandmother!"

Li Zexuan smiled.

He doesn't really care about the cycle of cause and effect and the rewards of goodness. He does good deeds just to seek peace of mind for himself!

Gradually after a while, the blue-yellow charcoal flame sprang out along the coal hole, and the inner wall of the coal hole was also burning red. Li Zexuan exclaimed with a slightly excited expression: "Alright!"

Then he picked up the briquette in the charcoal basin with tongs and carefully put it into the coal stove. Then he piled another briquette on top of the briquette, and the positions of the coal holes between the two briquettes coincided with each other.

After everything was over, he looked at Li Jingmo and said with a smile: "Father, how is it? This briquettes burns not much slower than charcoal, right?"

Li Jingmo didn't say anything, Ye Guozhong stared at a few briquettes scattered on the ground in surprise, and exclaimed: "It's amazing! This seemingly useless piece of coal is so easy to burn by you, Xiaoxuan! This is really a way to turn stones into gold!"

Charcoal prices in the Tang Dynasty were not cheap at all, especially in the early Tang Dynasty. There is a record in the "Old Tang Book" that "the volunteers were tens of thousands, and they were in the capital. The salaries were expensive but the cloths were low." It is said that in the early Tang Dynasty, due to the initial establishment of the country, all the volunteers from various regions were concentrated in the capital. The rise in the price of firewood.

Although the prices were cheap during the Zhenguan period, the price of charcoal was basically maintained at around 700 or 800 yuan per stone (100 catties). The price of good smokeless willow charcoal is more expensive!

Don't think that a pound of charcoal for seven or eight cents seems inexpensive, but this is a consumable item! How long can a pound of charcoal burn?

For wealthy people like the Li family, they don't care about the charcoal money, but for the people, burning charcoal is equivalent to burning money! How many can afford it?

In the late Tang Dynasty, Taoist poet Cao Tang described the kitchen in the fairyland in his "Ninety-eight Poems on the Little Traveling Fairy": "The kitchen maid cooks something, and the stove is full of smokeless jade red."

In Cao Tang's view, cooking with charcoal is just a wonderful fantasy in the fairyland. This poem just proves the reality of charcoal use at that time, that is, for ordinary people, it is not easy to use charcoal for cooking. thing.

In fact, in the Tang Dynasty, the consumers of charcoal were mainly the upper class. Charcoal was provided in the salaries of the relatives of the emperor at the time, the first to fifth grade Beijing officials. During the Tianbao reign, Emperor Xuanzong of Tang even set up positions such as the accountant in the court to take charge of related firewood affairs, and in the court, he also set up a charcoal envoy to take charge of related affairs.

It is based on this that Ye Guozhong said that the briquettes made by Li Zexuan are a means of turning stones into gold! After all, those coals were hard to burn before, how different from rocks? But now with Li Zexuan doing this, it is completely turning waste into treasure and turning stones into gold! Behind this briquette is some great wealth!

"What point of stone becomes gold? This is obviously an infinite merit! Xiaoxuan, this briquettes should be cheaper than charcoal, right?"

Old lady Ye slapped Ye Guozhong's arm, then looked at Li Zexuan and asked.

Li Zexuan smiled and nodded: "Of course it's cheap, and it's a lot cheaper! Grandma, even if this briquettes is only sold for a penny, the grandson will not suffer!"

He is now a real "mining at home" type local tyrant. For him, briquettes only need to consider manpower and transportation costs. If they are spread evenly on each briquette, the cost is pitifully low! For a penny, he really can't afford to lose!

"Yo~! One penny? That's really cheap~!"

Mrs. Ye also has eyesight. From her visual inspection, she felt that a briquette was worth less than a catty. The price of less than a penny per catty is not too cheap compared to charcoal!

"Ah! Brother! The briquettes on top are also burning! It's so warm~!"

Lan'er stared at the coal stove for a long time, and suddenly yelled at this moment. Her little hand was touching the outer wall of the coal stove to keep warm, and her little face was full of excitement!

Li Zexuan took a look, then picked up a piece of briquettes from the ground and sent them into the coal stove. At the end, he said: "This stove usually puts three briquettes at the same time, so that the heat in it can be transmitted to the furnace mouth! Now below! The two briquettes are already burning, and the one above will burn faster! Xiaohe, go to the kitchen and help me get a copper pot and fill it with water by the way~!"

"...Yes, Master~!"

Xiao He responded and quickly opened the door and went out.

Ye Fashan guessed Li Zexuan's intentions and asked: "Cousin, is this to boil water on this stove~?"

"Yeah! That's right! In addition to being used for heating, the biggest use of briquettes is to boil water and cook rice! And its advantage in this respect is that charcoal cannot replace it~!"

Li Zexuan responded with a smile.

After a while, Xiao He returned with a copper kettle.

The kettles of this era are made of pottery and copper, but their appearance is still very different from modern kettles. Li Zexuan is too lazy to care about these things now, as long as he can use it to boil water.

Put the copper kettle on the mouth of the coal stove and open the lid of the coal stove's ventilation hole. After a while, the fire became more vigorous.

Less than a quarter of an hour later, there was a "creak" sound from the kettle.

Mrs. Li was surprised: "This briquette boils water really fast, much faster than firewood!"

Li Zexuan responded: "Mother! This thing not only boils water quickly, but also lasts for a long time. Don't think there are only three pieces of briquettes in it, but if it is only used to boil water, a piece of briquettes can burn for more than three hours at most before and after each day, which is a total of every day. Need to change four briquettes!

If you just keep the briquettes burning indefinitely, leaving only a small hole in the vent of the briquettes, a briquette can burn for about six hours, and only two pieces of coal a day need to be replaced. In this way, you can avoid the trouble of making a fire every time! "

Combustion requires a certain environment: combustibles, oxygen, temperature. A single briquette cannot be burned because it cannot maintain the temperature. Honeycomb briquettes can be burned normally in the stove, and at least two briquettes are needed in the stove. Generally, household stoves need to put three briquettes at the same time to boil water for cooking.

What Li Zexuan said is all his experience.

In his previous life, his family had burnt briquettes for at least ten years, so he knew all about the characteristics of briquettes!

Ye Yuzhu, Mrs. Ye and others waited, and they were shocked when they heard Li Zexuan's words!

When the coal stove burns for a day with a full fire, it only needs four briquettes, which is four cents! If you burn charcoal for a day, you will have to pay hundreds of dollars for less! There is a gap of nearly a hundred times between four cents and several hundred cents!

And even if you don’t use charcoal, you still have to use firewood! The people outside Chang'an City can indeed go up the mountain to chop wood, but the people in the city are all paying for firewood! Calculating this day’s firewood money is actually about the same as burning coal!

I have to say that this briquette is really saving money! And this thing has no smoke, so I don’t know how many times it is better than firewood!

"Xuan'er, this is a good thing! Don't you know how easy it will be to boil water and cook rice with this coal stove and briquettes! If this thing is sold, the people don’t care if they have money at home, Definitely rush to buy!"

Madam Li opened her eyes and smiled.

When she married Li Jingmo in her early years, she went from a rich lady who didn't touch the sun with her fingers to a virtuous wife who could go to the hall and the kitchen. She knew the difficulties of the kitchen best.

Before coal and petroleum were developed and applied on a large scale, almost no energy was as important as firewood. Among them, firewood is mainly used for cooking! That smoky taste is really a pain!

"Cousin! How much does this coal stove cost?"

Ye Fashan asked suddenly.

Li Zexuan groaned: "This coal stove is made of pure iron, and the cost is naturally higher. The cost of each stove is about 150 yuan~! But the life of each stove is at least five years, five years. There will be basically no problems within it!"

"One hundred and fifty liters... five years! It is indeed very cost-effective to use coal stoves and briquettes to cook water! But it is estimated that many poor people are reluctant to spend so much money to buy coal stoves at once!"

Ye Fashan, who was precocious, knew much more than his peers. He immediately saw what the biggest obstacle the coal burning law would face if it were to be implemented on a large scale!

"Xuan'er, can our stove lose some money and sell it to the people? Anyway, our family is not short of money now, it is the right to do good!"

Mrs. Li is kind, after listening to Ye Fashan's words, she couldn't help suggesting to Li Zexuan.

"Mother! Although the child doesn't care about money, doing good is not such a way! There are tens of thousands of poor people in this world, even if all the money in our family is scattered, it can't make a few waves! In the eyes of the child, doing good You also need to be sustainable. If you can’t do it this time, you won’t be able to do it next time! As for the price of coal stoves, my child will find another way, so don’t worry, mother~!"

Li Zexuan shook his head.

Those world-class rich men in the previous life, such as Bill Gates, donated almost all of their wealth to the fund under their own name for charity after leaving office! At that time, they also persuaded Ma (yun) to donate all of his property like them, but Dad Ma did not agree, because Dad Ma felt that if the money was donated to the poor, it would become dead money, and the poor ran out. That part of the money is completely gone, but the money is in his hands, but it is living money, which can be used to create more job opportunities, help more young people start businesses, and even help more poor people!

Li Zexuan thinks Papa Ma's approach is very clever!

And he is indeed rich now, but he is not yet rich enough to help all the poor in the world! Only by continuously accumulating strength can we continue to do good!

"Xuan'er is right! There are too many poor people in this world. If you are trying to lose money and help all the poor people, it is tantamount to killing chickens and getting eggs, not for long~! It's just Xuan'er you say there is still What is a better way~?"

Li Jingmo has been in business for half his life, and of course he understood the stakes involved. He first agreed with Li Zexuan's views, and then asked.

Except for Lan'er at home, everyone's eyes were cast on Li Zexuan.

Seeing Li Zexuan condensed his eyebrows~www.ltnovel.com~ Then he smiled and said, "Well, this method, wait until I come back from the palace tomorrow! Now that there is a coal stove, let's eat hot pot tonight~ !"

In winter, eating hot pot with the whole family around the stove is probably the happiest thing in winter!

In Li Zexuan's mind, the situation of his family eating hot pot during the Chinese New Year could not help appearing in his previous life, and his heart was a little bit sour.

"Hot pot? What is this hot pot? Can I eat it?"

Ye Guozhong lived all his life, but for the first time he heard the term hot pot, he couldn't help asking.

Li Zexuan was startled, wondering, is there no hot pot in this era? After searching the memory of his predecessor, he quickly changed his words: "Ahem! This hot pot is similar to antique soup, but the hot pot I made will be more delicious! Maid, go, help me prepare some food for my husband~ !"

"Book of Wei" records that in the Three Kingdoms era, when Cao Pi was proclaimed emperor in Han Dynasty, hot pots made of copper have appeared, but they were not popular at that time. In the Northern and Southern Dynasties, people used hot pot to cook pigs, cattle, sheep, chickens, fish and other meats. Later, as the domestic economy and culture became more developed and the cooking technology developed further, various hot pots also appeared one after another. By the Northern Song Dynasty, the pub in Kaifeng, Bianjing, had hot pot in the market in winter.

However, the hot pot at that time was not called hot pot, but Antique Geng, named after the "gudong" sound made when the ingredients were poured into boiling water. It is a unique delicacy in my country. In Bai Juyi's poem "Ask Liu Nineteen", "Green Ant New Brew, Red Clay Small Stove. If you come to the night, can you drink a cup of it?" He vividly described the hot pot at that time. Scene.

"Okay! Xiang Gong!"

Han Yuxi smiled, and quickly got up and followed Li Zexuan to the back kitchen!
