Robb led the Elf Elder towards the paper mill next to the West Wind Canal. Marianne pursed her little mouth, followed, and wanted to join in the fun.

The paper mill is a cement building. Recently, all new houses in Xifeng Town have begun to use cement, and wood is no longer used to build houses. Of course, limited to the cost and the output of cement, some houses are not all cement, but first build the walls with bricks, and then paint a layer of cement on the outside of the bricks.

Robb also knows that this is a compromise under the constraints of cement production. Even in later generations, many rural houses will be built in this way. In this era, it is a dream to switch to cement to build houses.

This paper mill has adopted this approach, laying bricks on the walls and applying a layer of cement. The roof is directly glued with cement to form a pool for waterproofing. In this way, the roof becomes a reservoir, which can provide tap water to the factory building and reduce the water supply pressure of the big water tower in Xifeng Town.

Due to the rapid expansion of Xifeng Town, the large water tower built by the old mayor of Xifeng has long been unable to keep up with the development. Now Xifeng Town has begun to divide the area and build multiple water towers. Different water towers supply water to different areas and begin to faint. With the posture of a big city.

Before entering the factory, the Elf Elder saw a huge pool next to the factory, near the West Wind Canal. The sewage from the paper mill entered this pool, and then a few elven magicians stood by the pool. Continuously cast purification magic on these sewage.

He couldn't help but curiously said: "What is this doing?"

Robb said: "You don’t know the old man. Papermaking is very polluting to the environment. If dirty water enters the West Wind Canal, it will affect the ecology of the river, destroy the cat’s fish farming industry, and may even destroy it. The beautiful Westerly Canal turned into a smelly ditch. I know that elves are the race that loves nature the most, so I spent money to invite these elves to purify the sewage. They love nature and are willing to purify sewage. It’s really not a good idea to make money."

"So that's it." The elder elder glanced at the few elven magicians: "My elves came to do this, no one told me, and still treat me as the youngest?"

The two elf guards behind him were sweating profusely and said: "Elder, we have notified you that it was the Archdruid who invited my clan mage to purify the sewage and asked your opinion. You were writing the script at the time and had no head He lifted the floor and said, "Oh, go," and then ignored it."

Elf Elder: "..."

Marian next to him: "Puff!"

The elder elder turned his head and said, "You are laughing at me."

Marianne shook her head and said, "No, no, I respect the old man, how can I laugh? Unless I can't help it...puff...puff hahahaha..."

The elf elder had to shook his head: "Oh, people are getting old and have a bad memory. They are being laughed at by young people."

Robb continued: "It is not a long-term solution to always use manpower to treat sewage. Now it is just a compromise. I am asking alchemists to study the problem of using alchemy to treat sewage. In the future, alchemists will invent a potion. , It can be neutralized into clean water by pouring it into sewage."

The Elder Elder said: "The Archdruid really has the intention to take care of the environment when developing the city. The people of the forest goddess Melika sincerely express their gratitude to you."

Robb smiled: "Whether you are a believer of the forest goddess Melika, anyone who lives in this world has the responsibility to protect the environment. After all, this is closely related to everyone's life. Thank me. What to do?"

While talking, everyone came to the gate of the paper mill. Someone had gone in and informed Shang Hui, and she soon greeted him.

Now she is no longer wearing a western long skirt. During the time when the holy city Xifeng was engaged in a paper mill, she bought cloth and came back. Whenever she made an eastern long skirt, she finally got something for a lady in Hanfu. The taste, the only regret is that this rabbit head, Miss Rabbit Head in Han clothes, is just a little bit less interesting.

Robb said to her: "I brought these friends to visit the paper mill."

"Visit?" Shang Hui was stunned, and then said in Chinese: "Mr. Priest, this...I am afraid it is not very good. Our technology is not passed on to outsiders."

Robb smiled and said, "Moreover, it doesn't pass to daughters, right?"

Shang Hui was embarrassed: "There is indeed such a rule, but my father has only me as an only child, so there is no way to pass on daughters, unless we hire a son-in-law."

Robber laughed loudly: "I understand that the East has these rules, but to be honest, these rules are a bit irrational. Many techniques and knowledge can only be passed on from sons to daughters, so bad rules can only be passed on by word of mouth, leading to loss. It’s a pity... I think it’s a bad habit. And there’s really nothing to keep secret of papermaking. It’s rotten in the East, isn’t it? Besides, I’m engaged in assembly lines and mass production. There are countless people in this factory. Workers, it is almost impossible to prevent them from spreading it out. Even if people are not allowed to visit, sooner or later some workers will leak their skills."

He has said so, and Shang Hui has nothing else to say: "Well, then please come in and visit these few people."

Everyone entered the paper mill, and then slowly looked over the production line...

To be honest, this is also Robb’s first visit to the paper mill. Before, he just invested money and added BUFF to the people who built the plant. He sat on a stone chair to learn about it remotely. He was completely indifferent to the specific process of papermaking. Clearly, taking this opportunity to learn about the traditional and old technologies of the Chinese people is also a part of learning.

(I won’t talk about boring technology here, fast forward...)

Everyone looked at it step by step next to the production line, and saw that at first it was a row of large pots. Various raw materials were steamed in the pot, then degummed in the lime solution and decomposed into fibers. Then the workers began to beat the pulp, cutting and pounding the fibers to turn them into pulp. Next, papermaking, the pulp is soaked into water and turned into a slurry, and the slurry is picked up with a stick mat, so that the pulp forms a thin layer on the stick mat.

Then put the bamboo mat in the sun to dry.

Finally, the dried thing was peeled off and it became a thin sheet of paper.

The Elf Elder was holding a piece of paper that had just been removed from the mat, and his face was full of excitement. He gently stroked the piece of paper with a strange feel, his white beard trembling, and said with joy: "Good stuff, use With such cheap materials, you can make such good paper, my literature! My literature is about to fly, hahahaha, literature is about to fly!"
