At the Smithing Academy.
"Your Highness."
The official in charge of the Blacksmith's Academy greeted him from afar and bowed respectfully.
"No need to be so polite."
Liu Chen waved his hand and handed the formula of the waterwheel and the nitrogen, phosphorus, and potash fertilizer to the official in charge.
"The waterwheel can save manpower and operate automatically by water. NPK fertilizers can speed up the growth of crops and increase production…"
Hearing Liu Chen's explanation, the official in charge of the Blacksmith's Academy said with a pleasantly surprised expression,
"This item will definitely increase the yield of the farmland and reduce manpower and material resources. Your Highness is truly a peerless genius!”
"If I didn't invent it, your flattery would have hit the nail on the head.”Liu Chen scolded with a smile.
"Impossible!"
The official from the Blacksmith's Academy said in shock,"In this world, other than a genius like Your Highness, who else can make such an ingenious invention!”
Liu Chen's expression was calm, but he was cursing in his heart.
No wonder there were always people who wanted to climb up since ancient times. Listening to their subordinates bootlick was indeed a sense of accomplishment!
"Alright, let's get down to business."
Liu Chen also took out the formulas for cement and red brick.
This was related to the future reconstruction of Chang Shan's houses and road construction. They could not be careless.
"This is the formula for cement and red bricks. The Forging Institute will immediately research and produce them. If you have any questions, you can come and ask this king.”
Liu Chen handed the formula to the official in charge of the Blacksmith's Academy. This person had followed Chang Shan since his father's time and was absolutely loyal to his duty.
Of course.
There were too many secrets in Chang Mountain in the Blacksmith's Academy. It was also guarded by elite soldiers and monitored by every official.
It wasn't that Liu Chen didn't trust them, but he had to be wary of them. Even if he relaxed, the soldiers and strategists under him did not dare to relax.
After the official in charge of the Blacksmith's Department received it, he raised his eyes and scanned the materials on it. He was shocked when he saw them!
Having dealt with these for many years, he quickly saw that these formulas were unusual.
"Your Highness, this subordinate will immediately start preparing.”
Liu Chen and Qiushou did not leave either. Instead, they followed the official in charge to observe.
The forging of cement and red bricks had to be carried out in a furnace, so the Forging Academy naturally had no lack of furnaces.
Liu Chen noticed that the coal excavated from the coal mine had already been used as fuel in the Forging Yard.
Compared to charcoal, the temperature of coal was higher.
Looking at the furnace, Liu Chen suddenly thought of " glass ". If he had time, he could start producing glass.
In fact, glass had existed since ancient times.
However, the ancient glass was just a simple " low-temperature lead-bis glass ", which could also be called " glass ".
Colored glass was colorful and sparkling, but it was light and fragile. It was not resistant to high temperatures and could not adapt to sudden cold and heat. It was not suitable to be used as a living vessel.
The " glass " that Liu Chen was referring to was soda-lime glass. It was sturdy and durable, and would not explode in the face of heat.
Not only could it be used as food utensils, lighting for doors and windows, glass mirrors, glass greenhouses, but it could also be used to make binoculars, short-sighted glasses, and presbyopic.
It could be said to have a wide range of uses.
……
While Liu Chen was daydreaming about the glass, the official in charge of the Smithing Department kept persuading Liu Chen to leave.
After all, it was hot and stuffy here, and it was not suitable for Liu Chen to come here.
However, Liu Chen didn't care at all. The appearance of cement and red bricks had a tremendous change in the construction.
The red bricks were quickly refined. After all, they only needed to use clay to make adobe. The coal cakes and adobe were put into the kiln to be fired, which was roughly the same as the firing of the green bricks.
However, green bricks needed water during the firing process, but red bricks did not need water.
After the red brick was successfully baked, the test would be carried out amidst everyone's surprise.
In the end, he realized that the red bricks were not as sturdy, resistant to alkali-base, or durable as the green bricks.
However, the firing process, energy consumption, production, and cost of red bricks were far lower than that of green bricks.
It could be said that the production was simple, the efficiency was high, and it could be applied more widely.
"Although red bricks aren't as good as green bricks, they'll be perfect with cement.”
"The cost of building houses will be greatly reduced," Ju Shou commented in surprise.”
Liu Chen nodded. Now, they were just waiting for the cement to be produced.
However, it had always been difficult to refine cement. Either the strength was not enough, or the quality was not up to standard.
Everyone racked their brains but could not come up with a solution.
At this moment, Liu Chen suddenly saw the fan and understood the problem.
Whether it was cement or red bricks, they all required extremely high furnace temperatures. However, without the support of an industrial system, the temperature could only be raised by oxygen combustion and fuel.
He changed the charcoal into coal and increased the temperature of the furnace. However, this was not enough. He still needed to increase the oxygen to support the combustion, which was to blow the air into the furnace.
However, the current air blasters used airbags to blow air, so the efficiency and wind speed were obviously not good.
"Bring me a pen and paper."
Liu Chen waved his hand, and someone quickly brought a pen and paper over. He described the structure of the bellows in his mind.
There were still many things in Liu Chen's mind. These were all miscellaneous books that he had read in his previous life. Perhaps because of his transmigration, his memory had improved.
The bellows only appeared in the Ming Dynasty. After Liu Chen's drawing, everyone gradually saw this object from the future. Then, their expressions were somewhat bewildered!
"Alright, let's start manufacturing immediately."
Most of the items required for the bellows were made of wood. After an hour of modification, the first wooden bellows finally appeared.
After the small official pushed and pulled, a strong wind blew into the furnace, instantly causing the temperature to rise again.
"The temperature has increased!"
"Your Highness is really a god! This bellow is also good for our iron smelting!”
"Wonderful!"
Everyone was shocked. The increase in temperature meant that Liu Chen's bellows were indeed useful.
Moreover, it was more effortless to push and pull compared to blowing air from an air bag.
"Continue firing the cement." Liu Chen nodded and smiled.
After Liu Chen's modification and the addition of the wooden bellows, the temperature of the kiln increased again, and the cement was quickly baked.
After a series of processes, Liu Chen looked at the cement of the future. He did not mind the dirt and reached out to grab it. He was a little excited.
After the test, the combination of cement and red bricks was indeed flawless. Be it strength, strength, speed of cohesion, etc., they were all excellent!
"Gongyu, in the future, we will use cement and red bricks to build brick houses. I'll give you the blueprints for the construction and the heating beds.”Liu Chen said.
Next, not only did they need to build new houses, but they also needed to renovate the heating works of the houses. The fire kang would undoubtedly come in handy.
At that time, the Chang Mountain generals would no longer have cold winters!
"Yes, sir! My lord!"
Ju Shou and the others cupped their hands and promised.
Liu Chen nodded and continued,
"We need to increase the amount of cement and red bricks.
"I'm also preparing to build roads with cement to connect the various counties of Chang Shan. When the time comes, the problems of marching, trade, food transportation, and so on will be greatly improved.”
"Yes, sir! Your Highness!"
The official in charge of the Blacksmith's Academy and the surrounding officials cupped their hands and agreed.
Liu Chen did not stay any longer after receiving a series of orders. He left the Smithing Department with Ju Shou.
As soon as they walked out of the door, Tian Feng and Guo Jia rushed over.
