"Let's go!"

The iron workshop was steaming, and with Zheng Tu's shout, the fiery molten iron rolled down the iron groove from the iron furnace, followed the pouring mouth, and entered the sand mold, endlessly.

Zhao Hong smiled slightly. This rich second generation is still a promising young man with pursuits.

After one sand mold is poured, the next sand mold is poured, and there are as many as twenty or thirty.

"Your Highness, it will take about three to four days to open the mold, and then clean the gun body and polish the gun chamber."

Zheng Tu's face was lit by the fire, and his voice was full of confidence.

"Zheng Tu, do you have confidence in the artillery you forged?"

Zhao Hong unconsciously asked about the little fat man.

"Your Highness, the villain will tell the truth, at least more than seventy percent!"

"Good! I just want you to have faith, and I have faith! ”

Zhao Hong spit out a "golden sentence" and hurried out of the iron workshop.

What did the later generations say: I want me to feel, not you think.

When everyone came out of the iron workshop, they were all sweating, and their heads and faces were steaming.

The summer is scorching, and the temperature in this iron workshop is extremely high, so it can be said that it is sweating like rain, but it is not comfortable.

"Li Tang, write it down, and add 3 yuan per month to each blacksmith who smelts iron. Homosexuals...... The craftsmen are so hard! ”

Zhao Hong's compassion arose spontaneously.

After going back, these things must be implemented immediately, and I believe that the Ministry of Industry will not obstruct them.

Hu Yu, the secretary of the Ministry of Industry, is a clever ghost, generous to the court, and believes that he will not restrain himself.

"Your Highness, please look!"

In the shed outside the iron workshop, Zheng Tu laboriously took out an iron ball from the wooden box and let Zhao Hong watch it.

"This is an artillery shell? So smooth? ”

Zhao Hong looked at it for a moment, and then looked at the iron balls in the wooden box, all of them were smooth and glowing.

"Your Highness, not bad! This is a 7-pound iron ball, heat it slowly, and then polish it, and the surface will be smooth. ”

Zheng Tu introduced, Zhao Hong nodded ignorantly.

Although he doesn't understand these crafts, he also knows that this Zheng Tu is a talent.

With such a smooth shell, the damage to the chamber will be greatly reduced.

"Zheng Tu, are you willing to follow your father and continue to smelt iron and cast firearms?"

Zhao Hong immediately made a decision.

What he likes most is talent, especially young people. Now that Tian Yi is not here, casting firearms, someone needs to set up a field here.

"Your Highness, the villain is willing!"

Zheng Tu was overjoyed, and his face trembled.

"Alright! Now the firearms casting in the ironworks are all under your control. Including the production of artillery and grenades, it's up to you. Although Tian Tisha no longer holds an official position, he is still your boss. In the future, we still have a lot to do, and we have a long way to go. Do you understand? ”

Zhao Hong solemnly took the matter and told him seriously.

Smart people don't need to be too thorough.

"Your Highness Thank you! Tian Daguan, a lot of support in the future! ”

Zheng Tu respectfully saluted Zhao Hong and Tian Yi.

Who doesn't know that Tian Yi is Zhao Hong's confidant and brother. He knew his position, and he was not arrogant enough to challenge Tian Yi's authority.

"Zheng Tu, these days, we have been living in the village. If there's something, just call us. ”

The cooling of the cannon blank, coupled with cleaning and polishing, can take four or five days. Shaoxing Lin'an runs at both ends, and the gains really outweigh the losses.

"Your Highness, the gunpowder is almost ready. Look, what should I do? ”

Zheng Tuxing rushed away, Tian Yi asked subconsciously.

yes, what to do?

The toothbrush is already available, the toothpaste is not good, and the ceramic is the quintessence of the country; Glass, bone china, pendulums, looms, and steam engines do not seem to be things that can be done in a short time.

Soap, soap! Saponification reaction!

Zhao Hong's brows immediately stretched.

In the current situation, soap is short and flat, and it doesn't delay things, so you can try it.

As a college student who graduated from the Authentic Pheasant Normal School, and came from the later generations of the knowledge explosion, he still understands these basic operations.

A large amount of straw is burned into ashes, one part of plant ash, two parts of water is boiled and steamed, and the next day, almost without filtration, it is alkaline water.

Hydrated lime is dissolved into an aqueous solution, alkaline water is added, calcium carbonate is precipitated, and the above is sodium hydroxide solution, commonly known as caustic soda solution.

The caustic soda solution is heated, vegetable oil is added, and the oil is fully dissolved to form a solution, which is the saponification reaction.

Soap is produced by adding fine salts to the resulting solution, the so-called salting-out action.

Just do it, act resolutely, Zhao Hong immediately ordered to go down.

"Tian Yi, let's ...... like this"

Some things, which seem ordinary, may be able to promote social development and promote people's employment.

Five days passed, Zheng Tu did not come to ask Zhao Hong to see the artillery casting, but Tian Yi hurriedly came over, pulled Zhao Hong and left.

"Let's go! Check it out! ”

Zhao Hong was a little expectant, but he didn't ask, and followed Tian Yi out of the room.

When I arrived at the courtyard of Zheng Hao's house, sure enough, the three floors inside and the three floors outside were full of villagers who came to see the excitement.

In the middle of the courtyard, Zheng Hao's wife was washing her clothes in a wooden basin with an irregular crooked rectangular square.

"Behold, in the hour of incense, five garments were washed, and they were clean. What a good thing! ”

Zheng's wife said happily, showing off her washed clothes.

Some villagers went up and washed their hands with suspicion, and they were amazed again and again.

"It's really clean! Cleaner than a bath! ”

All the villagers went up one after another, washing their hands and washing their hands, and they were all amazed.

Such a clean thing is indeed a rarity.

"Your Highness is a good means!"

Seeing Zhao Hong appear, all the villagers saluted and made a way, all respectfully.

This prince of the Great Song Dynasty is a noble man and understands a lot, unlike those gentlemen who don't learn and don't know how to do it.

Come to think of it, everyone can smelt iron, let alone soap.

"Your Highness, can this thing wash your hair?"

A villager asked loudly.

"Absolutely! But it's best to close your eyes, this soap is still a little irritating, but it doesn't hurt your hands! ”

Zhao Hong pointed to the strange-shaped soap balls that were cut one by one like dogs, and shouted loudly with a smile on his face:

"The villagers present, one person took a piece, went back to wash clothes, wash hair, bathe, and the child liked to wash his buttocks. If you don't get it, you will get it next time, Zheng Yuanwai will register it for you here! ”

"Your Highness!"

"Your Highness is benevolent!"

The villagers smiled happily and stepped forward one after another, and Tian Yi and Li Tang launched soap for the villagers.

This prince has some vulgar words, but he listens to it closely.

"Classmate Tian, you are really a tyrannical thing. Such a good soap makes you look like this, and people who don't know think it's a piece of shit. Yours is it! ”

Zhao Hong looked at Tian Yi and was angry.

"Your Highness, don't worry. Isn't this just trying it out? I'll make some molds and make them into various shapes, which are guaranteed to be beautiful and easy to use! ”

Tian Yi said with an embarrassed smile.

"Well, the appearance should be beautiful, and it is best to match the beautiful packaging of the tin box and wooden box, so that it can be sold at a good price. When the time comes, let the tabloids publicize and keep the money you earn. Now, you know what you're supposed to do, right? ”

Zhao Hong passed on his business experience to Tian Yi.

Idle is also idle, let Tian Yi do the promising career of soap and soap.

"Okay, I'm just doing this temporarily, and the money from the sale is also from the imperial court. In this way, what you do can be seen by the officials and those courtiers. ”

Tian Yi's words were meaningful, and Zhao Hong nodded lightly.

Anyway, Tian Yi and they are not bad for money, and they have made "achievements", which are beneficial to themselves and harmless.

Tian Yi hesitated for a moment, and suddenly said:

"Your Highness, soybean oil is too expensive, can you use lard?"

In contrast, lard can be much cheaper than soybean oil.

"Absolutely!"

Zhao Hong laughed, and almost said "why not".

The main ingredients of fatty oil and vegetable oil are basically the same, there may be some small differences, but the essence is the same, they are both raw materials for making soap.

"That's good. Otherwise, it's a waste of things! ”

Tian Yi nodded, relieved.

"When I go back, I buy some spices and make soap into soap, which looks good and makes money for the rich and noble. Remember, without the permission of me, the chief engineer, the craft of making soap cannot be passed on! ”

Zhao Hong told seriously.

Spices? Chief engineer?

Tian Yi nodded ignorantly.

Soap is a luxury, and the price of the "soap" made cannot be low.

"Your Highness, you really made Liang blind enough for the villain's eyes!"

Xu Sheng used Zhao Hong's mantra and sighed heartily.

"In the past few days, you have also helped a lot, go back and make soap, and send a few pieces to each of you!"

Zhao Hong laughed.

"Your Highness, I'll talk about the soap later. Let's give the brothers a few bars of soap first. ”

Li Tang smiled awkwardly with a dark face.

"No pursuit at all!"

Zhao Hong shook his head and looked around.

"What about Lao Zheng? Why don't you see him come out? ”

"Your Highness, Lao Zheng is in the backyard, and he is beating that honeycomb coal!"

Zheng's wife said with a smile

In the backyard of Zheng's house, the sound of "jingling" came, Zheng Hao was wearing a sleeveless two-crotch vest, with a short crotch on his lower body, barefoot, holding a coal hammer in both hands, and was playing honeycomb coal, sweating profusely, and he was happy.

Look at the eaves next to him, there are already one or two hundred cylindrical honeycomb briquettes piled up. It seems that Zheng Hao has been busy for a while.

Li Tang and the others surrounded one after another, and they didn't help, but their eyes widened and they watched Zheng Hao panting and performing.

"Your Highness, you sit down first, drink tea first!"

Zheng Hao was sweating profusely and kept moving, and his little daughter hurriedly came up and obediently made tea for Zhao Hong.

Now, everyone knows Zhao Hong's habit of drinking bubble tea instead of tea powder.

"Thank you!"

It seems that Zheng Hao's tutor is good, and the children are polite without the slightest arrogance.

"Your Highness, how many days will this honeycomb coal be dried?"

Zheng Hao asked while playing briquettes, panting.

"With such good weather, one day is enough! Usually sunny days, two or three days at most. ”

Zhao Hong sat down, looked at the courtyard, and continued to ask:

"Have you made the stove?"

"Your Highness, that one is simpler, much easier to get than an iron-smelting stove. The stove is already dry, so bring it right away! ”

Zheng Hao put down the coal hammer and went over to take two pieces of whitish briquettes.

"Your Highness, please take a look, this has been in the sun for a day, can you see it?"

"Lao Zheng, you're very efficient!"

Zhao Hong looked at the briquette, pinched it with his hand, it was strong and did not fall off the slag, and nodded slightly.

"It should be fine!"

In just four or five days, not only the coal hammer was built, but also the honeycomb coal, and now everything is ready, only the Dongfeng coal furnace is owed.

"The coal stove is coming!"

While speaking, Zheng Hao's second uncle, blacksmith Zheng Erxing, rushed into the yard with a honeycomb coal stove.

"Let's get started."

Zhao Hong nodded lightly and gestured.

"Chopping wood, making a fire!"

On the firewood, the honeycomb coal was burned half of the body red, Zhao Hong picked up the tongs, picked up the briquettes, put them into the honeycomb coal stove, and then clamped two pieces and overlapped them.

"Your Highness, can this really work?"

Zheng Hao was suspicious and looked at the stove in front of him.

If it does, it might be a good way to make money.

"Zheng Yuanwai, you must believe in me, believe in science, and believe in the wisdom of the people!"

This is all the crystallization of technology that has been tempered and tested by life, how can it not work? .

"Your Highness, you are a great talent, of course the villain believes in you!"

Zheng Hao was smiling all over his face, flattering Zhao Hong.

"Zheng Yuanwai, you put your heart back in your stomach. In the future, you can count the money well! Remember, my royalties, don't forget! ”

Zhao Hong smiled slightly, very embarrassed.

It is the crystallization of the wisdom of the working people, and he is just standing on the shoulders of Zheng's father and son, Tian Yi and others.

Thinking of something, Zhao Hong put down the teacup and solemnly admonished.

"Zheng Yuanwai, remember to change coal, about three or four pieces a day, and the seal below can adjust the speed of burning. Remember, if you burn it in your house, make sure you leave the window or door open, at least a little gap. Otherwise, people will die! ”

Carbon monoxide poisoning is no joke!

"Also, when selling, be sure to tell all the people who buy the stove about the precautions of poisoning, don't be careless. Otherwise, if you get into a lawsuit, you will go bankrupt and go to jail! ”

Zhao Hong said with a solemn face.

"Your Highness, rest assured! Be careful, villain! ”

Zhao Hong's face was serious, and Zheng Hao also replied seriously.

The houses in the countryside are all closed. Even in the city, there are almost no airtight houses.

"Zheng Yuanwai, don't worry! Sell it for a year or two, and then the daughter's dowry will be there! ”

Zhao Hong laughed.

Honeycomb coal is convenient and energy-saving, and it will surely become the favorite of thousands of families in the Great Song Dynasty.

"Your Highness, can you burn like this, three or four briquettes a day, and don't make a fire all year round?"

Li Tang looked carefully around the honeycomb coal stove, his eyes full of doubts.

"Remove your "?" word, it will definitely work! ”

After taking a sip of tea, Zhao Hong said slowly.

"It's okay to smoulder the fire, why can't honeycomb coal? When the time comes, it will definitely scare you into the farm manure! ”

How can it not be a product that has been tempered and verified by the times in later generations?

Sweeping his gaze in the direction of the iron workshop, Zhao Hong's brows furrowed slightly.

Zheng Tu, this kid, should be making artillery.
