As long as it can cover the surface of the object and form a solid continuous film, it can be called a coating.The coating itself can be gaseous, liquid, solid, and uses different.From the initial beautiful decoration to the later protection of the durability of the object, it is regarded as a kind of coating.

Roland then began a series of tests.

The test results made him extremely happy, probably affected by the concept of "the longer the painting can be preserved as soon as possible", her previous photo painting has been difficult to completely clear if it is not destroyed, and the ability to evolve has raised this feature to a new height.

First of all, this high-focus, light-quality "pigment" in the physical properties of two very different characteristics can be based on the different painting objects to change the flexibility of their own material, for example, in painting the sky or clouds, it is soft like marshmallows, stretching and shear have a very high resistance.When replaced by iron ingots and glass, it becomes hard and brittle, and can be directly broken with a hammer.In other words, due to the limitations of quality, its performance in terms of flexibility is far better than rigidity, which is also in line with Soroya's understanding of pigments.

Secondly, no matter which characteristics are shown, its chemical properties are very stable, not only does not react with dilute sulfuric acid and dilute nitric acid, but also shows repulsiveness to water and oil.When he filled a paint-smeared carton with water, there was no sign of water seepage at the bottom of the thin box.After pouring out the water, the clear liquid beads roll in the box, like dew on the lotus leaves.Touch the bottom with your finger and it still feels dry.

In the high temperature test, Anna dripped iron water into the paper box, and the paper as the carrier suddenly caught fire, but the coating itself did not change much except for being propped up by the iron water.It was not until Anna's black fire continued to heat up and burn the coating, it began to melt and deform, while white smoke, and finally turned into a black glue.

What excites Roland most is that the coating is also insulating, and can be seen as a coating line for future generations after the copper wire, he proved this with the simple DC generator in the yard.

At this point, Roland has a complete understanding of Soroya's new abilities.

Unlike Anna's black fire, which transcends the green flame in all aspects, her ability to evolve is more like an extension of her previous painting ability, and now she can draw a realistic "painting oil painting" or draw the previous thin "photo painting", which only depends on the idea in her brain, and the two abilities can be used in parallel.

In addition, when drawing a volume with a thickness, if the thickness is controlled below one centigram, Soloya can almost keep painting several hours.Once more than three centimeters, the magic consumption will increase rapidly, and a threshold will be reached after ten centimeters, almost exhausting the whole body magic is only enough to draw a pen or two.Of course, from another point of view, this is also the fastest and most effective way to vent in the face of magic phages.

It is still a calling power, and within the bounds of the stone of divine punishment, the magic pen suddenly disappears, and Soroia can no longer draw new patterns.However, the coating that has been painted will not be affected by the stone of divine punishment, and under the observation of the nightingale, there is no trace of magic left on it, in other words, the material generated by the magic pen is real.

As for the use of the coating... that’s too much.Soroya herself would never have imagined how much her new abilities could change the town, which meant that Roland could quickly get a batch of water pipes coated with rust-proof materials, as well as large bundles of enameled wires and even high-temperature fire-resistant bricks.The three-way project that seemed unreachable (water, electricity, and path) suddenly saw the dawn.

At the same time, it also gives him a reminder that the knowledge of personal experience is far deeper than the axioms in the book.

If the witches could see the microcosm more intuitively, would it accelerate their acceptance of particle theory and trigger a new round of evolution?Microscopy that can observe cell structure and microbes.

Roland felt the need to try it.

North of the kiln.

“The drumbeat!Let the fire burn a little more!”Lois shouted.

Although you can't see the scene in the vertical furnace, but with the three cars of charcoal poured in, the iron stone inside should have burned red.

When Carl van Burt called a letter to the border town, he thought it was a barren place, and if it had not been written that the stonemason might have been reborn here, he would not have been willing to go beyond the borders of the kingdom to practice his old business.

After taking a break from the family, after packing up and leaving, he has been ready to drink rare porridge and live in tents, as for no one, no money, it is a problem that is often encountered during construction.

Losa did not intend to stay in the border town for a long time, to see Karl, an old friend who had known him for many years, to see that the stonemason would be exiled or reclusive with his companions, and he was satisfied.

But reality is always so incredible.

After arriving in the town by boat, he met Karl van Burt, the outstanding stonemason of the Grey Fort King, and a strong contender for the next leader of the guible.Compared with the appearance of memory, he has white hair on the corner, and there are several more wrinkles on his face, but his body is not thin, but he is strong a lot, and there is even oil on his face.

After a little chilling, Karl did not take him to the noisy and cluttered construction site, but brought him to an apparently new residential building, and handed him a key and said, "This room is yours, put your luggage away, let's go to the tavern for a good drink."

Then Losya heard a series of incredible stories from the other side.

Carl, as a civilian, was recruited into the town hall by the lord, becoming a monthly fixed-pay official and the head of the construction department!

If you stay by yourself, you can also work in the city hall!

Give away a free home!

After ten years, you can get a retirement allowance!What is the retirement allowance?You can get money without working!

Los Adam thought Carl was drunk, but he didn’t think... what he said was true.

"Adult, the ore is melting, I see the flow of iron!"The worker at the top of the stove shouted.

“Open the scum!”

After entering the work, none of the problems envisaged by Loso Yas appeared, and the above not only asked people to pay, but also paid for them, but also gave them very quickly, often after the application, and the next day they could receive a reply.In addition, the site also produces a kind of alchemy material called cement, which can quickly bond bricks and stones, making the construction speed by leaps and bound, and he actually felt an unprecedented smoothness here.

In just one month, Losa built five furnaces with a wind bag and three for ironmaking.

The vertical furnace in front of him was the work of conspirators after he left the masonry meeting for many years, and the works of gathering the experience of the past, I thought that it could only be passed down in the form of drawings, and I did not expect that there would be a day of turning into a finished product.

This improved vertical furnace is nearly two meters high and has an inner diameter of about 75 centimeters.The lower part of the furnace has a number of tufts, which can be used to blow the wind and convulse, and the bottom is left with slag and iron flow outlet.Next to the vertical furnace, there are also soil slopes with sand and gravel, which facilitates workers to feed and observe the situation in the furnace.

Today is the day when the first vertical furnace is officially put into use, and before the furnace is opened, it is customary to do a smelting test.

After opening the slag more than ten times intermittently, and adding two cars of charcoal to the furnace, the inspection basically declared that there was already a bottom of the iron in the qualified stove, the slag mouth was unimpeded, and the temperature could meet the smelting needs at this moment, and there was no need to continue to waste charcoal.After all, in order to reduce the loss, the first furnace inspection, the use of waste mines in the corner of the yard.

Opening the iron vent to drain the already melted ferrosome, Losia announced a halt to the furnace.

...

Two days later, the townmen who cleaned the furnaces laid out several dark stones.Under the high temperature baking, other waste mines have been reduced several times, but these ores have not changed with the past just thrown into it, but the surface is more bright, black and ink-like.

Losia could not judge what kind of ore it was, saying that it was a useless waste mine, its shape and appearance were really pleasing, not useless, but if it is useful, how to make it into an artifact if it cannot be smelted?Thinking about it, he simply picked out a piece of the most correct ore, wrapped in cloth, let his men go to the castle, and give it to Roland Wembton, lord of the border town.

Perhaps the well-informed Lord knows the answer.(Unfinished.If you like this work, you are welcome to start the project, and your support is my biggest motivation.Mobile phone users please read.)
