After testing, Snow found that a one-for-two ratio of sand and water was the most practical. The pen & fun & pavilion www.biquge.info has good adhesion and strong plasticity, too little water is not strong, and too much water is not formed. After the proportions were determined, Snow mobilized the whole town to start working in full swing. Last night's beast attack made the residents nervous, and they worked hard to strengthen the fence.

Under Snow's inspection and guidance, the big guys piled up layer by layer on a half-foot standard. While the fence is gradually raised, water is poured indirectly on the fence. By the time the walls were piled up to ten feet high, there was a layer of solid thin ice on the surface of the middle and lower walls, which provided a good protection for wild beasts to climb the walls. Snow decided to sprinkle more water on the wall every evening, slowly using ice to increase the thickness of the wall.

By the time everything was done, it was already dawn. But the inhabitants were still in good spirits, partly because Snow protested against the rhetoric of the church and the aristocracy, which brought a huge spiritual shock to everyone.

On the other hand, I am very satisfied with the effect of the new wall. Over the years, the success of netting and reinforcing the wall overnight is one of the proudest things for the residents. From time to time, everyone shuttled back and forth between the walls, looking at the masterpieces they had completed with their own hands, and their faces were full of joy. At the same time, looking at Snow's eyes, he admired and respected him even more.

However, everyone also wondered why Snow had given up reinforcing the northern wall of the town. You know, the north side of the town faces the endless mountain forest, and it is the gate of Rook Town. If the beasts of the Endless Mountains come out and attack the town, the north will bear the brunt. Snow, on the other hand, strengthened the other three walls, staggering the areas that needed the most protection, which was a bit of a trivial.

But this time, no one questioned Snow anymore, and there were many doubts about fishing and digging sand to strengthen the fence before, and the final results showed that Snow's approach was completely correct. So everyone took the initiative to choose and trusted Snow completely and unconditionally.

Originally, Snow was still meditating on how he should explain if someone asked questions. I can't say that there will be wild beasts coming to help watch the gate. Although people's attitudes towards the church and the aristocracy have changed greatly, fundamentally, many people still fear and believe in the church.

Especially some of the older people, who have been believers for decades, want to completely shatter their faith with a rhetoric, which is not possible. So Elena and Yalian can't be exposed as wizards yet.

"It's almost dawn, let's let the big guy go and rest." Looking at the sky, Snow said to Abra beside him, "I have to work hard to protect the guards and patrols, and take turns to keep guards." "After Snow's reorganization, the number of convoys has increased to twenty, and the patrol has already taken the initiative to join.

"It's our duty, Mayor, please rest assured." Now that the walls have been strengthened and heightened, it is now difficult for small beasts to climb in, and the convoys and patrols only need to focus on the north side of the town. And it's about to get dark, and most of the beasts don't choose to attack the town during the day.

At Snow's orders, the residents began to cook, and this was the earliest breakfast they had eaten in so many years.

After eating, everyone went back to their rooms to rest. Snow finally strode into the bedroom today, and since he had returned to town, he had met Arlene, and since that day he had slept on a bench on the first floor.

Plunging into the soft futon, Snow smelled a faint fragrance, and couldn't help but have layers of ripples in his heart, this is Yalian's body fragrance. Turning over and lying on the bed, looking at the empty room, Snow couldn't help but miss Yalian, the beautiful witch. I don't know how she is doing in the mountains and forests, Xi is not used to it. Although she knew that with Elena by her side, safety would not be a problem, Snow was still a little worried.

"When we get through the beasts and survive this damn winter, we will start building Rooktown." Snow had already made a general plan in his heart, with his mind, he could first use the ancient shaft furnace method of iron-making to extract raw iron from iron ore. After Snow obtained the pig iron, he naturally borrowed Yalian's fire magic and transformed it into steel.

The difference between steel, pig iron and wrought iron basically lies in the amount of carbon. The carbon content is between 0.0218% and 2.11%, which is steel. If it is greater than this value, it is pig iron. Less than this value is wrought iron.

If you want to make pig iron into perfect steel, you need to do four off, two go, and two adjustments. That is, to remove carbon, oxygen, phosphorus, sulfur, gassing and inclusion, and adjust the composition and temperature at the same time. The most commonly used means are oxygen supply, slag making, heating, deoxidizer and alloying operations.

Snow knew that there are three main types of large-scale steelmaking methods, namely converter steelmaking, open-hearth steelmaking, and electric arc furnace steelmaking. Just listening to this lofty name, you know that with the technology and conditions of this era, none of the three methods is feasible.

However, Snow didn't want to eat a fat man in one go, since the conditions did not allow it for the time being, then he only needed to refine ordinary steel. A shaft furnace is made of heat-resistant clay and then charcoal is used as fuel to heat the pig iron to between 1,100 and 1,500 degrees Celsius, and it melts. Then, by agitation, the carbon contained in the molten iron is fully burned to form wrought iron.

Because wrought iron is so pure, existing technology alone is not enough to melt it, and melting wrought iron is a necessary condition for the steel filling method. At this time, it is up to Ya Lian, and her black flame is fully capable of doing this.

In this era, people did not know how to make steel, and the simplest carburizing method had not yet appeared. They also don't know the value of the carbon contained in the steel, and they don't have the technology to control the carbon content. Therefore, most of the iron ore is made of block iron and pig iron.

Once a block of smelt iron and pig iron is obtained, the alchemist will use a method to convert it into wrought iron.

Because there are many impurities in fast smelting iron and pig iron, the melting point is low. Alchemists can melt it into a liquid state with coke combined with a blast device, which is then stirred to fully burn the carbon inside and convert it into wrought iron.

These wrought iron will be sent to the blacksmith shop for hammering and forging, in fact, the wrought iron can absorb the carbon in the charcoal through the process of charcoal heating and hammering, improve its own carbon content, and smelt into steel, which is the simplest carburizing method.

However, today's blacksmiths do not know how to carburize, and charcoal is rarely used when forging, so these wrought irons are still wrought iron in the end.

Because wrought iron is too soft, it can be easily bent. Therefore, many knights' wrought iron weapons or bronze weapons are scumbags in Snow's eyes.

The amount of steel in this era was very small, and occasionally blacksmiths inadvertently used the carburizing method to get some steel, but they were confused and did not understand the reason, and thought that it was the role of the raw materials themselves. And these occasional steels have become sought-after goods and are precious items. Only nobles above the viscount have a chance to get it. But they are also reluctant to make it into weapons, and most of them are made into decorations to reflect their status and identity.

Therefore, if Snow can use the steel filling method or carburizing method to make steel, it will undoubtedly be a great fortune.

First of all, it is possible to create extremely sharp weapons, and in this era of wrought iron and bronze as weapons, a steel sword is, of course, a sword without a doubt. Sharpening iron like clay and sharpening bronze like clay is definitely not a legend. Just imagine how many gold coins can be exchanged for such a sharp weapon. Snow had no doubt that with steel, he could quickly earn his first pot of gold.

Snow thought about the carburizing steelmaking method he had learned before, and the famous steel-filling method, and fell asleep unconsciously.

Maybe it's because of the day and the night, Snow meets Yalene in a dream, and he also dreams of the sexy Elena.

Just as Snow was dreaming, he suddenly heard the sharp whistle that made people panic again.
