The correct way to open the sprite

Feng Yu helped Dick design some large-scale vessels so that Dick could bake stone powder on a larger scale to meet the needs of building salt fields. At first, Dick was worried that large-scale production of stone powder was not necessary because the salt fields needed to be constructed step by step.

Feng Yu told Dick that he was going to build a hardened layer of stone powder into the water channel leading to the sea. This would not only reduce the soil debris brought up by the flow of sea water, but also prevent the fresh water underground from diluting the sea water and making it more difficult to dry the salt. .

The most important thing is that Feng Yu wants to build a turret on the seaside of the canal. It doesn't need to be too big, but at least the height should be able to prevent the murlocs from climbing. It can accommodate a team of about ten elven archers or dwarf musketeers. Remote military units are provided with accommodation to prevent murlocs from damaging the channel mouth or polluting the sea water.

Feng Yu also revealed that more stone powder can be used to make building materials to build houses for the dwarves to live in, eliminating the need for everyone to sleep in tents and make floors.

Dick looked at Feng Yu and asked: "Don't you know why no one builds houses?"

"I know, aren't we just planning to run away? But now that the salt field has been repaired, how can we run? Can the salt field follow us?"

Don't worry, Dick, I will create more powerful weapons again to protect our wealth.So what if I’m a mercenary? If I haven’t had a fight, I won’t become a deserter in despair.”

Dick looked around and whispered: "It's not just humans."

Feng Yu patted Dick: "I understand, but even if we only live here for ten or eight years, we have to live in a tent."

"What can we live in if we don't live in tents? There are no salt fields, so we have to work hard to store food and materials in exchange for salt and other daily necessities. There are not so many people who hand-fire stone powder to make houses. It is too luxurious.

The dwarf royal city was built by gathering the labor force of most of the dwarves. "

Feng Yu had seen the paintings of the Dwarf King's City in Dick's tent. The large-scale vaulted buildings made of stone powder were the work of the dwarves piece by piece. They were indeed majestic.

However, it was made to gather the confidence of the dwarves who were driven out of their homes by humans. There is only one building in the royal city that belongs to the dwarf king. The rest are basically public buildings, such as the historical museum, the ore research laboratory, etc. This Dick had told him.

Feng Yu thought that that kind of construction method was not as good as digging a rock mountain as a royal city. Anyway, dwarves were good at building mountains, and natural rocks had a much longer shelf life than concrete buildings.

Obviously, the dwarves have not really figured out the use of stone powder and large-scale firing methods, but now that they know the material and firing process of stone powder, they can make stone powder on a large scale and make the best use of it. This comes from concrete. What Feng Yu of the forest is best at.

After Feng Yu showed Dick on the spot what prefabricated panels and hollow bricks were, Dick became interested in building a house. Who the hell would want to live in a tent if he had a house?

"We'd better exchange salt for a batch of wood. Using the river transportation method you mentioned, we can use very little salt to exchange for a large amount of wood. In this way, we can also build beautiful doors, windows and furniture."

Feng Yu patted Dick on the shoulder and said, "Brother, please think carefully. When the time comes, remember to help me build a sturdier big bed."

Dick laughed twice and patted Feng Yu to show that he understood. Unfortunately, Feng Yu was standing this time, and Dick didn't pat the right place, so he really flattered him.

While Feng Yu was trying to use various materials to make glass, he also asked Dick to help him build a paper-making workshop. Without paper, it was impossible to write records. This not only delayed the students' learning, but also hindered many planning, design and craftsmanship efforts. There is no way to record the process, so it can only be passed down by word of mouth, which is very troublesome.

Feng Yu didn't know how to make rice paper, the kind used by emperors and ministers, but he only knew how to make broken straw paper.To put it bluntly, wood fibers such as scraps of clothing, rags, torn fishing nets, branches, and straw are repeatedly crushed and boiled. This process is called pulping.

Finally, the impurities are filtered out, and something like thickened soup is obtained, which is pulp.After the pulp is blended and diluted with water, a water-permeable mold is used to scoop it out so that the fibers in the diluted pulp are evenly distributed on the mold.

After the thin layer of paper on the mold is dry, slowly peel it off. After collecting a certain amount, press it with a heavy object to squeeze out the water and make it thin and flat.

When it is dry to a certain extent, peel off the pressed paper one by one, and then dry it.

It is said that putting the pulp in the sun for two or three months can whiten the pulp, or add bleaching powder.Obviously Feng Yu can use bleaching powder, but unfortunately he doesn't know how to make it. He does know how to make soap, but it's a pity that it requires animal fat. That thing is a rarity in the camp, and there is not enough to make soap.

Feng Yu can't wait two or three months. If the papermaking experiment is almost completed in the future, maybe he will make better paper. But now, everything is based on practicality. Even if the paper is yellow or gray, it will not be the same. Not delaying use is not.

It's not yet time for the little pots in the camp to use sky blue paper to protect their eyes. Besides, isn't he developing glass? If you are short-sighted, you can use glass to grind your lenses. Anyway, the elven gem masters are so good at polishing gems. It's quite round, so there's no reason why the lens can't be ground out.

Anyway, as long as the glass is developed and the materials are determined, it can be fired on a large scale and polished slowly. It will be no problem anyway. Do we still expect them to make the eight-fold mirror on the demon-slaying sniper in Feng Yu's plan?

Even if there is no coating process, Feng Yu can accept a lower magnification. The double scope is much better than the machine sight. At least it can also have a front sight engraved on it.

Anthony was convinced by Feng Yu's tormenting ability.

The earliest books on the Green continent were divided into copper plates and animal skins according to their rarity. Later, humans discovered that the bark of the rotten white maple tree was thin, white, and tough after being paralyzed on the stone and dried in the sun. With the expensive white maple paper, it was exclusive to the royal family, nobles and great painters.

Later, relatively cheaper wooden paper made of other materials became available, but the relative price remained high.

Now, Feng Yu told him that paper is just a cheap thing. As long as he is willing to cut down trees, he can have as much as he wants. His purpose is to let students use paper to study and write. How can this not make him feel toothache every time he buys a notebook? Anthony was surprised.

Anthony is a great mage, and he doesn't think there are many expensive things.

Table salt has now been developed by Feng Yu. He has also developed porcelain tableware and pottery vats that are more beautiful and practical than the sterling silver tableware used by nobles, solving the problems of eating and storing water in the camp.
