The underground world lacks sunlight, lacks trees, and the only thing that is not lacking is endless soil and stones, which are one of the most useful resources in the underground world, but not all stones are useful, some stones are beautiful, but they can only be used as decoration, and some stones simply do not even have the advantages of being good-looking, and belong to the type of children that no one wants.

If you want to develop your own strength, the mining industry is a direction that can be developed, because the mining industry can do more than just mining, it can also be used to dig tunnels, in the underground world, naturally generated tunnels extend in all directions, and it is easy to go to other people's territory, if you don't want to develop along the naturally generated tunnels, then you can only risk a little cave collapse, to dig up the wall, expand the space.

It is time-consuming and laborious to use ordinary manuscripts to expand the space, so the white wolf has developed an automatic mining machine, which is not full of knives, but a metal machine driven by electricity, which is driven by runes and looks like a gun, and when you pull the trigger, a thunderstorm will shoot out of the muzzle, and finally blow a big hole in the wall.

This lightning blast mining machine is fully automatic, can be automatically charged, and works every ten minutes, although the frequency is a little slower, but the large crater bombarded by each explosion is better than the results that can be obtained by twenty goblins digging together for ten minutes.

The white wolf drew a thunder element circle in the machine, and of course added its own original self-excitation rune to it, without which it would be impossible for the thunderstorm mining machine to be automatically charged.

In addition to mining and burrowing, this machine can also be used to defend against enemy invasions, thunderstorms once every ten minutes, can cause significant damage to the enemy, but before the white wolf's territory was still in a hidden state, don't worry about the danger of invasion, now, someone has found their traces, the white wolf is thinking about whether it should more or less strengthen the guard force of the territory, so he moved an automatic mining machine to the entrance of the cave.

"I'm still too weak.... What's the use of this automatic mining machine? If it's really overwhelmed by someone else's army, it's just an ornament. The white wolf thought about it for a while, and then moved the mining machine back to its original place, and let it continue the mining operation, otherwise it would be a waste of resources to put it at the entrance of the cave, as for defense, it is enough to have the fog of red leaves, anyway, if the fog can't be prevented, it is useless to ask for this automatic mining machine.

The white wolf has built a total of 5 automatic mining machines, and they are running at low power, which is due to the instability of the lightning element, if the power is full, it is easy to overload the mining machine and burn it, and it takes a certain amount of time to clean up the mined things, to collect useful raw materials and throw useless raw materials out of the territory.

At present, White Wolf is mining a small iron mine, and the iron produced every day can be used to make about 5 iron swords, this small iron ore was discovered by White Wolf by accident, and it is not known how long it can be mined before it will be exhausted.

After the iron ore is mined, it can not be used directly, and it also needs to be crushed, throw away the useless stones, leaving useful parts, the crusher is two large and hard stones driven by the earth element array, put the mined minerals in the middle of the crusher, and manually open the self-excitation device by the person, the two big stones will quickly hit the middle, and after the clang, these minerals are crushed into pieces.

After sorting out the useless parts of these small pieces, what remains is the relatively high content of iron ore, and in order to extract iron from iron ore, this iron ore must first be put into a blast furnace. Then the coke distilled from the excavated coal is put into the blast furnace, and the bottom of the blast furnace is engraved with a flame array, and after the flame circle is opened, a very high temperature hot gas is sent from the bottom of the blast furnace, causing the coke to burn.

Coke burning, which produces carbon oxides, due to the lack of air, incomplete combustion, this part of the oxide contains a large amount of carbon monoxide, carbon monoxide and coke at high temperature with iron oxide reduction reaction, carbon into carbon dioxide, and iron oxide into iron. At high temperatures, the iron melts into a liquid and is discharged with some residue to become pig iron.

With no readily available tools at hand, the white wolf had to design iron smelting from scratch. The blast furnace and coal distillation device had to be designed from scratch, and the temperature control was the most difficult joint, but after hundreds of attempts, the white wolf finally succeeded, looking at the molten iron flowing out of the exit, he knew that he was finally worthy of dragging his small tribe from the primitive society into the Iron Age.

With iron, many production methods can enter a higher stage, and the production efficiency is also greatly improved, the white wolf took a batch of goblins, and made the first batch of iron into hammers and pliers, with these two things, the difficulty of casting can be reduced, after that, the blacksmith shop appeared in the white wolf's territory.

Under the command of the white wolf, the blacksmith first produced a batch of agricultural tools for harvesting mushrooms, and after the agricultural output increased, the blacksmith shop created a batch of short iron swords to increase the force value of the goblins who explored the path.

The white wolf remembers that the foreign goblin team was holding a sharp bone spear and a stone hammer in his hand, these things are not enough in front of the hard iron weapon, and in the future, the white wolf will try his best to produce a batch of armor for the goblins, if the craftsmanship level of the armor is too high to make it, then it is okay to make a few iron plates tied to the body, and after having these thin iron plates, there is no need to worry about the stabbing of the bone spear.

The goblins were in a bad state of life, and every day they could hear the explosions coming from the automatic miners, and the clanging from the grinders, and the clanging sounds coming from the iron, and at first they thought these sounds were quite novel, because they had never heard them before, but after a long time, they began to get bored.

After all, these sounds belong to the category of noise, many goblins have poor patience, and they have been a little crazy with the noise, and they have begun to attack the people around them non-stop, and the white wolf has no choice but to set a downtime for these instruments, so that they will not make sounds all the time, and there will be 8 hours of downtime every day, and then they will start working again.

Although there was only a short gap of 8 hours, the white wolf still felt that it was too much of a loss, if these 8 hours were used, how much iron could be produced? machines were not as tired as living creatures, as long as there were enough elements, they could continue to work.

The white wolf felt that he had lost a lot, so he decided to move the living area to the spider's lair, and this territory was used as an industrial area.

The noise is really not something to enjoy, and the sound of tinkling is always in my ears, not only the goblins, but also the white wolves, foxes, and black wolves.

With these machines, the development of the White Wolf Territory is finally on the right track, and according to his vision, the technical level of his territory is at least one generation higher than that of the surrounding countries, so that his plan can be smoothly advanced.

As for the refrigerator and water heater, it is actually a simple application of the rune circle, several water attribute circles are combined together, which can cool the inside of the container, and similarly, the combination of several fire attribute circles can heat up the inside of the container.

Although the automated machinery reduces the happiness of the goblins because of the noise, but it also liberates a large number of laborers, the white wolf organizes all the adult but not too old goblins, conducts military training on them, and at the same time selects some of the smarter goblins and teaches them how to open these automated machines.

However, the use of these instruments is all after the White Wolf Demon has changed, and before using them, these goblins have to recite a bunch of prayers in praise of the wolf god, and by the way, add some strange, ritual-looking, but meaningless movements.

The white wolf tells the goblins that the automatic machines they have given them can keep them away from the pain of labor, but this gift is not unconditional, and if you want to use them and make them work, then you must have a firm belief in the wolf god, recite prayers, and perform rituals to show your loyalty to the wolf god.

In fact, this set of rituals is useful, after these goblins do it step by step according to the instructions of the white wolf, these automatic machines are really activated, and the white wolf splits the action that is really useful and can open the self-activating runes, and blends it into this set of rituals, with the goblin's brain, they can never figure out that most of this action is actually useless, these guys who believe in the white wolf believe that every word of the white wolf is correct, and this concept has been repeatedly emphasized in the rituals, becoming more and more rooted。

Only the white wolf himself knows what he is doing, he wants to create a new religion based on runes, and ordinary people have no way to understand the knowledge of runes, so it is enough to simply explain all this as the gift of the wolf god without letting them understand.

This new religion has an advantage that other religions do not have, that is, it responds to requests, as long as this set of rituals is completed, then all kinds of incredible things will definitely happen because of the operation of the rune circle, which is much more intuitive and credible than ordinary religions.

Looking at this group of goblins who were clumsily repeating the ritual, the white wolf smiled, this will be the first clerical class he has cultivated, and in the future, he will retreat into the background, no longer contact with ordinary goblins, and become a god who is truly elusive and powerful in the hearts of goblins.
