The problem of the lich can only be solved slowly, but the pace of industrial development in the territory cannot be stopped.

The lord had rarely let go of countless official duties, and came from the Silver Dragon Castle, far away from the mountains, and had already made up his mind to finish the battle and lay the industrial foundation of the town before winter came.

In this era, the lack of iron in the territory is a common problem, and whoever can take the lead in increasing steel production can achieve a huge military advantage.

With the coke oven, the problem of coking can be regarded as a preliminary solution, and with the assistance of the high temperature of Yanmo, the necessary pre-technology coal preparation and coal blending for coking can also be slightly simplified.

Coal mining was not a problem for the dwarves, but they never considered separating refined coal from raw coal due to the extensive use of coal and the fact that high-temperature ironmaking was never considered.

If you want to coking, the ash, sulfur, moisture and phosphorus content in the coal will affect the quality of the coke, so Vincent planned to use the washing process to obtain clean coal from the beginning, but this is easier said than done.

The dwarves also knew that in order to obtain coal that could be coking, the coal had to be selected, and the traditional method was relatively simple, sieving large pieces of coal, hand-sorting and tool crushing, separating impurities such as coal, gangue, and yellow iron, and extracting the refined coal for use.

In addition to letting children do this simple and boring work, the dwarves chose to force the slaves to work after the bandits entered the town, and kept them busy between screens, hammers and soot.

After the arrival of the lord, the process of child labor coal preparation was completely abolished, and the undead creatures were directly added to the coal preparation process, for skeletons, it is not difficult to crush and sieve the coal, and larger pieces can also be distinguished, but the color of the coal still needs to be distinguished by experienced dwarven miners.

The skeletons do not consume physical strength or rest, except that the pale color of the bones is quickly tarnished by cinders, giving them an indescribable grayish-black color.

Coal preparation is just a preparatory process, in addition to increasing the production of coking coal, so that more coal can be turned into coke in the wild dance of the demons, but also to further improve the quality of coal.

Drawing on the principle of the jigger, Vincent solved the problem of washing coal with a mixture of mechanical and water magic, and under the diligent work of the water magician in shifts, the heavy gangue and the light refined coal were separated.

The peat in the sewage will not be wasted, it will be filtered and recycled before being recycled, and the filtered slime once again plays a huge role, and also avoids serious environmental pollution and water waste.

To increase the efficiency of the crushing, Vincent first built a winch and gear-driven roller crusher, which used cattle to grind smaller pieces of coal, but for larger pieces of coal, this method was not very efficient, effective, and even less consistent.

"A better way is the jaw crusher, we all call it the "tiger's mouth", this kind of machine is like a big mouth that keeps opening and closing, constantly opening and closing when large minerals enter, and the moving jaws on the top hit the static jaws below, so that the crushed ore continues to enter the crushing chamber, except for coal, all kinds of minerals can be used."

Vincent approached Kalul, who was also busy, and told him what he had in mind.

"An animal's mouth? The principle is very simple, and it doesn't sound difficult, after all, it's just opening and closing up and down." The dwarven craftsman who was able to create the golem agreed with the lord, and half-jokingly proposed his own idea, "Since it's a big mouth, I wonder if our guardian dragon will help."

"Such a clean and beautiful dragon, I can't bear to make such a request, and one thing, I don't want to become the second Iwabeard."

This idea sounded like he was going to kill himself, and Vincent shook his head again and again, wondering if this guy Kalul had been going too well in his career recently, otherwise how could he have such an unreliable idea.

No more golems, and Kalul was not depressed, instead plunging into a new attempt to develop a rolling stock for the rails, and with Vincent's help, he could quickly get the parts he wanted, so progress was fast.

In fact, Vincent had a set of models of steam engines that had been successfully experimented with for a long time, and because of their relatively small size, he also habitually rubbed a set of train scenes

Watch the sand table and put it in the castle for yourself to play with.

This train toy is not of much interest to others, but Prani has a soft spot for this kind of vehicle that can run on its own, and every time she goes in, she will stare intently, gazing at the train over town, over hills, through tunnels, climbing bridges, and even the whistle "whining" sound, which makes him cheer and then think about it.

At one point, Vincent asked why, and Plani said that the witch's hometown was too isolated, and that if the machine could reach it, it would definitely bring about a change in the dead witch's homeland.

What is the place to change, but Prani's hometown? Vincent knows better than anyone how much rail will affect the local economy, but how difficult it is to make it happen.

Without an industrial base, there would be no infrastructure, and there would be no leaps and bounds in the economy.

The steam engine is not a problem, but the strange thing is that in order to please the gods, Vincent relied on epoch-making machinery to get more protection, and spent time and effort rubbing the steam engine model, and actually got a reward of 1,000 points of protection from the craftsman god.

Knowing that this was a revolutionary driving force that had changed the history of another world, Vincent was shocked at the time, and even complained that he didn't know the goods.

"This machine is ingenious, and it is certain at the time that it is not the best choice in this world," Krafts, the craftsman god, told Vincent through the system, "Apostle, this is not enough."

In fact, Vincent himself thinks that if the beginning and the end of science are boiling water, the world is too boring, and in a world where gods and magic are rampant, it will not be a pleasure to go down this path.

With the protection of the craftsman, if the model is enlarged, it will definitely not be a problem to use the power of the steam engine to drive the crusher, but the steam engine is a large consumer of coal and steel, and Vincent does not plan to consume precious resources to manufacture it before the basic industry of the territory is built.

Another point is that compared with the more efficient and compact magic stone drive device, the efficiency and cost ratio of the steam engine is too low, as a device destined to be replaced on a large scale in the future, why spend resources to develop it in the first place?

Magic plus technology, it must be magic technology, in order to exert the greatest power contained in this world.

In this world, people who don't know how to use magic can also use magic arrays to drive magic power, and Vincent has always wanted to figure out the relationship between magic arrays and magic, and develop the corresponding magic drive system by himself.

So, he wanted to find an expert in this area, Kalul, to study it.
