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

Roland then carried out a series of tests.

The test results made him extremely happy. Perhaps influenced by the concept of "the longer the painting can be preserved, the better", if her previous photos did not destroy the carrier, it would be difficult to completely remove them, and her evolutionary ability even raised this feature to a new level.

First of all, this pigment with high adhesion and light weight shows two completely different physical properties. It can change the flexibility of its own material according to the different objects of the painting. For example, when painting sky or clouds, it is soft like a marshmallow, and has extremely high resistance to stretching and shearing. When replaced with iron ingots and glass, it becomes hard and brittle and can be directly smashed with a hammer. In other words, due to the limitation of quality, its performance in flexibility is far better than rigidity, which is also in line with Soloya's understanding of pigments.

Secondly, no matter which characteristics it shows, its chemical properties are very stable. Not only will it not react with dilute sulfuric acid and dilute nitric acid, but it also shows repulsion to water and oil. When he filled a paper box with paint coated with clear water, there was no sign of water seeping at the bottom of the thin box. After pouring out the water, the clear liquid beads rolled in the box, like dew on lotus leaves. At this time, touching the bottom with his fingers, it still felt dry.

During the high temperature resistance test, after Anna dripped molten into the paper box, the paper used as the carrier immediately caught fire and burned. However, the coating itself did not change much except by the molten iron. It was not until Anna's black fire continued to heat up and burn the coating that it began to melt and deform, and white smoke came out, and finally turned into a ball of black gel.

What excited Roland the most was that this coating was also insulating. After covering the copper wire, it could be regarded as an enameled wire in later generations. He proved this with the simple DC generator in the yard.

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

Unlike Anna who surpasses the Green Flame in all aspects, her evolutionary abilities are more like an extension of her previous painting abilities. Now she can draw both realistic oil paintings and thin photo paintings of the past. This only depends on the ideas in her mind. The two abilities can be used in parallel.

In addition, when drawing a scroll with a thickness, if the thickness is controlled below one centimeter, Soloya can almost keep drawing for several hours. Once it exceeds three centimeters, the magic consumption will increase rapidly, and after ten centimeters, a threshold will be reached, and almost all the magic power is enough to draw one or two strokes. Of course, from another perspective, this is also the fastest and most effective method of venting when facing magic body sapling.

It still belongs to the summoning ability. Within the effective scope of the Stone of Divine Punishment, the Magic Purse will suddenly disappear, and Soroya cannot draw new patterns. However, the paint that has been drawn will not be affected by the Stone of Divine Punishment. Under the observation of the Nightingale, there are no traces of magic left on it. In other words, the substance generated by the Stone of Divine Purse is real.

As for the purpose of the coating... there are too many. Soloya herself would never have thought about how much change her new abilities could bring to the town, which means that Roland could quickly obtain a batch of water supply pipes coated with anti-rust materials, as well as large bundles of enameled wires, and even high-temperature fireproof bricks. The three-way project that seemed out of reach (water, electricity, and pathways) suddenly saw the dawn.

At the same time, this also gave him a reminder: the understanding of personal experience is far deeper than the axioms in the book.

If the witches can see the microscopic world more intuitively, will it accelerate their acceptance of particle theory and trigger a new round of evolution? For example...a microscope that can observe cell structures and microorganisms.

Roland felt it was necessary to try it out.

North slope furnace kiln group.

"Blow the breeze! Let the fire burn more vigorously!" shouted Losya.

Although I couldn't see the scene in the vertical furnace, as three trucks of charcoal were poured in, the iron and stone inside should have burned red.

When he was called to the border town by Carl Vanbert, he thought it was a remote and barren land. If it weren't for the letter that the stonemason might have reborn here, he would not have been willing to run outside the border of the kingdom to reopen his old career.

After leaving for a while, he packed his luggage and set off, he was ready to drink porridge and live in a tent. As for asking for no one or no money, it is a problem that he often encountered during construction.

Losya did not intend to stay in the border town for a long time. He was satisfied with seeing Carl, an old friend who had known for many years, and seeing the stonemasons who were exiled or secluded.

But reality is always so incredible.

After he arrived at the town by boat, he met Carl Vanbert at the dock, an outstanding stonemason in the Grey Castle King, and a strong contender for the next leader of the guild. Compared to his memory, he had white hair on his temples and a few wrinkles on his face, but his body did not lose weight, but became much stronger and even had oil on his face.

After a while, Carl did not take him to the noisy and messy construction site, but led him to a clearly newly built residential building. He also handed over a key and said, "This room is yours. Put your luggage first, let's go to the tavern to have a drink."

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

As a civilian, Carl was recruited into the city hall by the lord and became an official with a fixed monthly salary, and was also the supervisor of the construction department!

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

Free one house!

After working for ten years, you can get a retirement allowance! What is a retirement allowance? You can get money even if you don’t work!

Losya thought Carl was drunk at the time, but he didn't expect... what he said was true.

"Sir, the ore is melting, I see the molten iron flowing!" shouted the worker at the top of the stove.

"Open the slag outlet to discharge slag!"

After he started working, no problem conceived by Losya appeared. The superior not only asked people to give money, but also gave it very quickly. He often got an answer the next day after applying. In addition, an alchemy material called cement is produced here, which can quickly bond masonry and stone, which made the construction speed soar. He actually felt an unprecedented pleasure here.

In just one month, Losya built five furnaces with blower bags and three vertical furnaces for iron smelting.

The vertical furnace in front of him was the work he had thought about for many years after leaving the stonemason meeting and gathered the great success of his past experience. He thought he could only pass on it in the form of drawings, but he did not expect that he would still be turned into a finished product.

This improved vertical furnace has a height of nearly two meters and an inner diameter of about 75 cm. There are multiple air nozzles at the bottom of the furnace, which can be used to blow and exhaust air, and there are slag discharge outlets and molten iron outlets at the bottom. There is also a soil slope built with sand and gravel next to the vertical furnace, which is convenient for workers to add feeds and observe the situation in the furnace.

Today is the day when the first vertical furnace is officially put into use. Before opening the furnace, a smelting inspection must be carried out as usual.

After opening the slag outlet more than ten times intermittently and adding two trucks of charcoal to the furnace, the inspection basically declared that there was already a solid iron in the furnace, and the slag outlet was unobstructed. The temperature could meet the needs of smelting at this moment, so there was no need to continue wasting the charcoal. After all, in order to reduce losses, the waste ore in the corner of the yard was used for the first furnace lift inspection.

Open the iron outlet to discharge the melted iron, and Losya announced the shutdown.

...

Two days later, the townsmen who cleaned the furnace dug out a few dark stones. Under the high temperature baking, other waste mines shrank several times, but these ores did not change much from when they were thrown in. Instead, the surface was brighter and darker as ink.

Losya couldn't tell what kind of ore it was, it was said to be a useless waste ore. Its shape and appearance were really pleasing, not as if it was useless, but if it was useful and could not be melted, how could it be made into a utensil? After thinking about it, he simply picked out a piece of ore with the squarestick, wrapped it with cloth, and asked his subordinates to go to the castle and handed it to Roland Wimbledon, the lord of the border town.
