hao, for giving me this opportunity. I made this tofu myself!""However... Brother Zhao is right. I do intend to sell the medicinal water. In the next period of time, tofu probably won't be in short s...Yang Lin passed a thick drawing to Zhao Shunzi.

"So many"

Zhao Shunzi hurriedly flipped through the drawings, but the more she looked, the more confused she became.

"What's this"

"What's this again"

He's not illiterate, he just can't read the drawing because it's not a blast furnace at all!

The furnace on the drawing is way too big, and the requirements are incredibly demanding. Even building something like that would require a foundation!

"This, this is really a furnace for tempering iron"

I said, it's steelmaking!

"But, steel... what exactly is it" Zhao Shunzi scratched her head.

Let's put it this way, cast iron has the most impurities, followed by wrought iron, and steel has the least. Therefore, steel's hardness and strength are superior to both cast iron and wrought iron, making it a more advanced metal material.

Zhao Shunzi's eyes widened with excitement.

"Later, Uncle Shunzi, you personally select the people. If 20 isn't enough, we can add more. We need to get this furnace built as quickly as possible!"

Then, I will bring a new kind of fuel called charcoal. With charcoal and this furnace, it won't be a problem to smelt steel.

Patted Zhao Shunzi on the shoulder.

"Yes!"

Zhao Shunzi was also full of expectation.

"And also those kinds of parts, I'll build ten more sets in the next few days." Yang Lin said.

"No problem."

Zhao Shunzi agreed readily.

After finishing the task, Yang Lin and Du Jing entered the house.

"Lin Di, you just said making paper Are you serious"

As soon as he entered the room, Du Jing hurriedly asked.

Of course it's true.

But the paper is already very good now. Could you possibly lower the cost any further

Du Jing stared in surprise at Yang Lin.

Yang Lin smiled and said, "First of all, the cost can definitely be further reduced."

"Besides, do you really think, Jingge, that the paper we used to scare you is already very good"

Du Jing nodded blankly: "Is there any better paper"

Du Jing doesn't believe it.

In his view, paper today is already very good!

Very thin, very light, it won't rot even after decades.

That's why he couldn't figure out why Yang Lin would want to improve paper.

Is there still room for improvement

From the use of bamboo slips to the appearance of paper, for centuries people have used this kind of paper and no one thought it was inappropriate.

If you want to talk about drawbacks, there's only one word.

You!

Of course! And there's a lot of room for improvement, a very large amount!

Yang Lin sighed.

When he arrived in this world, he was very uncomfortable with the paper in this world.

Not only is it thicker and rougher than paper from the last life, but it's also yellowed, even blackened in places, and lacks flexibility.

Let alone compared to the paper from past lives, even Cai Lun's Cai Hou paper is far inferior!

"Really" Du Jing still didn't believe it.

"Of course," Yang Lin said, "the paper we are going to make will be lighter and thinner, with a soft texture, comfortable feel, bright white color, no impurities, and high transparency. It will be suitable for painting and magic spells, and even printing!"

Du Jing was dumbfounded. Although he didn't know what printing was, he couldn't imagine that the kind of paper Yang Lin described really existed

"I've written out the specific processes in detail."

Yang Lin took out a sheet of paper and handed it to Du Jing.

"There might be some details that are not quite right, or some deviations, so it needs continuous attempts and improvements."

Although Yang Lin said so, when Du Jing flipped open the manuscript, his eyes widened in astonishment. The more he read, the more shocked and amazed he became.

For a moment, he excitedly put down his writing and stood up with joy.

"I'm going to make paper now!"

If such paper could truly be created, one would undoubtedly go down in history!

Yang Lin smiled and nodded. "You can choose anyone you want, take as many as you need. If you have any special requirements, just come to me. Just remember to keep things confidential!"

"From now on, your Design Studio will be completely separated from the Smelting Workshop. I've gotten a new house for you, and you can move in with your people right away."

"Jing Ge, the papermaking business can not only create huge profits but also benefit generations to come. Although I already have a theory here, don't rush it. Study it diligently, and you will succeed eventually!"

As soon as Yang Lin left Du Jing, good news came from the riverbank.

Both cement and coke have been burnt!

When Yang Lin came to the riverbank this morning, he specifically instructed them to use the coal brought back by Lao Heishan to burn cement again and test it. He also taught them how to make charcoal.

The entire morning passed, and it was all successful!

When Yang Lin arrived, he hurried to try it himself. The result left him very satisfied.

Although the strength of cement was not as good as later generations, mixing it with sand and water did indeed make it concrete without a doubt!

As for charcoal, it's not possible to test the temperature at the moment, but the process of making it isn't complicated. As long as you follow his instructions, you'll definitely succeed.

"Uncle Dazhuang, at this rate, how much cement can we burn in a day" Yang Lin asked.

"This…"

The tall and strong man shook his head and sighed: "The burning process isn't difficult, just two hours. It's just grinding these stones, it's too much trouble! You see these we burned today, they're still the stone powder I've been saving up for days."

"If the whetstone could keep up, we could make at least twice as much today!"

Yang Lin estimated that the weight of this batch of cement was only about five or six hundred kilograms. It consumed a lot of manpower and material resources, but the output was still extremely low.

The main problem is still with the gravel.

Although limestone is quite soft, the process of crushing it first and then grinding it into powder would still be too cumbersome without a stone crusher nowadays.

"That way, I'll have the workshop build a new type of watermill specifically designed to crush stones. It will be at least five times faster than the old one! This way, we'll basically guarantee our supply of raw materials."

"From now on, this kiln will be used exclusively for burning cement, and the other kiln for burning bricks."

"Cement is afraid of moisture, so after it's fired, it should be directly transported to the construction site. With cement, we can start laying the foundation today!"

The foundation pit has been dug for many days, just waiting for the success of the cement.

"What Such expensive cement, used for the foundation"

Tall and muscular, he stared directly at me.

Although he had never personally experienced it, from the firing process alone, he could tell that making this cement was not easy.

The concrete, which was finally made after much effort, is supposed to be poured into the foundation pit...

I'm really broke!

Yang Lin smiled and said, "A solid foundation makes for a sturdy house!"

He certainly knew the value of the cement, but for safety, it was all worth it!

With cement, building houses can continue.

New waterwheels, papermaking, steelmaking, brick burning, road construction, and house building...

It seems like everything is developing in a positive direction.

Before I knew it, several days had passed.

In the evening, before the sun had set, outside Jianghe County, a group of burly men with bushy beards, armed with weapons and eyes full of malice, charged into the city under the waning sunlight!oThe tide has turned, we are both alone and abandoned. There is nothing we can change!Now that we are both married, even though I still don't like him, he has done us a favor, so I will just repay the...
