Chapter 15 The North Wind Mine

Whether it's an igloo or a pine resin for lighting, these are just stopgap measures. Pen "Fun" Pavilion www.biquge.info his goal is to unify the wolf cry, so with the same land resources, he needs to be productive as many times or even dozens of times the number of others, so that it is possible to defeat the lord with the land resources of the camp, defeat the city lord with the land resources of the lord, and defeat the demons and other city lords with the land resources of the city lord.

After walking with Li Sheng for about half an hour, several people came to the Beifeng mine.

The North Wind Mine is located on a hilly hill ground with undulating terrain around it. The so-called mine is actually a shaft more than ten meters deep, in which several miners are digging iron ore in the rock layer. These miners are actually very industrious, although there are only five people, these miners can chisel forty or fifty pieces of ore every day. The problem is that these shallow rocks contain too little iron, and the bonanza is generally at a depth of 20 or 30 meters. But in order to dig the mine, there are two problems that need to be solved.

First, if you continue to dig down, it is likely to cause a mine collapse.

Second, it is too deep for the miners' breathing problems, that is, the lack of air circulation.

The first problem is easy to solve, just build a thick layer of wood or stone walls around the mine wall. In the case of a stone wall, there is a problem of stone adhesion, and the first thing that comes to mind is cement.

Forget about the standard cement, the cement of the soil method can be ground with limestone and clay, and then calcined into a material, and finally the material can be made into a decent cement by grinding it with the slag left over after ironmaking.

There are currently two material processing plants and one material processing plant under construction, and I don't know how much slag is left every day, so this soil method is just right.

Looking at the busy appearance of the miners here, Zuo Zhen had the idea of building a kiln here.

Not to mention, this place is really an excellent place to build a kiln.

First of all, the material processing plant is here,

Secondly, there is plenty of stone here, and the soil is also clayey.

However, building a kiln not only requires a lot of manpower, but also needs to solve the cause of the high-temperature furnace. If you want to build a good kiln, it is unlikely to be built in ten days and half a month. In addition, the kiln that Zuo Jian envisioned should not only be able to fire bricks, but also produce cement, and preferably have the capacity to produce ceramics.

Suppressing the idea of building a kiln, Zuo Jian began to work on the specific improvement of the mine.

First of all, the mine was dug down 10 meters, and the walls of the shaft were temporarily cast into a wooden wall with thick cedar wood to prevent the mine from collapsing.

Then the ventilation adopts double ventilation, because this is a hill, and the location of the mine is relatively high, so Zuo Zhen decided to dig a wellhead in a lower place, and then dig a tunnel to connect the two shafts.

For the time being, that's all there is to it, as for the more advanced windmill pressurized wind, the wellhead is expanded into a square mouth, and a 'chimney' is built to form an air pressure difference, and the fresh air enters through the inlet, and the turbid gas comes out of the 'chimney', and the twenty-meter-deep mine is not yet needed.

The idea was decided, and the left mark first asked people to build a wooden wall and then dig ten meters deep, and then choose the address of the air outlet around it. After carefully circling around, Left Mark found a place on the downwind slope. The place was only twenty meters away from the mine, but the difference in height between the two was a full ten meters, and there was a direction in this place that happened to be the wind outlet, and the wind climbed up the hill from this side.

This is it!

"Li Sheng, you take a few people to dig a hole diagonally down in the direction of the mine, and you must dig it to the bottom of the mine. By the way, build several wind shields around this hole to let as much wind into the tunnel as possible. ”

After Li Sheng listened to Zuo Zhen's words, his eyes lit up, the wind came in through this opening, and then went down the diagonal tunnel to the bottom of the 20-meter-deep mine, and finally went out from the mine mouth, isn't this a perfect ventilation route? And because of the ventilation, the bottom of the mine can be dug more open, so that more people can come to mine.

"Yes, I'm going to tell them to do it." Li Sheng said with some excitement in his tone, looking at Zuo Zhen's gaze with more respect.

In order to fear that these workers would dig crookedly, Zuo Zhen also deliberately added:

"Align the position of the mine and dig down at an incline of 30 degrees."

sin30 degrees = 1/2.

The level of mathematics here should not be at the level of trigonometric functions, so Zuo Zhen needs to give one more command.

"Yes!" Li Sheng's gaze at Zuo Zhen has changed from respect to shock, general... There is such a high level of mathematical attainment.

It just so happened that the policy of the left mark allowed more people to put into production, and now a large number of people have been gathered casually. Because you give things according to how much you do, these people are particularly motivated to work. In Zuo Zhen's incredible eyes, it only took five hours for these people to do what Zuo Zhen commanded.

One by one, these workers looked at Zuo Zhen with adoring eyes, and their mouths were amazed.

"I've seen other people dig mines before, and basically they can't dig down until they dig fifteen meters, either the mine collapses or it is difficult to breathe, but this mine has no problems at all, it's amazing!"

"It's amazing, the battalion commander is really amazing, he can set up such an exquisite ventilation route."

"It's incredible, thirty degrees, the battalion commander said thirty degrees, but we dug down at this angle, and it happened to be at the bottom of the mine, no more, no less, just right, it's amazing."

The new mine is also twice as high as the three times expected on the left, and six times as efficient as it was before.

Coupled with the fact that it can be mined by 5 times more people than before, the efficiency of Left Mark Mining is theoretically increased by a factor of 30.

That's 300 iron ingots a day!

Is this a high yield?

It's very high, so to speak, there are so many camps around, only the top three can reach this terrible number.

But is it enough?

Inadequate!

It is simply not enough to build ten or eight guard towers in the severed limb barracks in a short period of time!

But there is no way to do it, the most important thing for the left mark now is to defend against Thorde's aggression, and he doesn't have that much time to develop slowly.

Otherwise, Zuo Zhen wouldn't have even visited the yak farm until now, although he is confident that the meat production of the farm will increase several times!

But does it work?

Thorde is not the commander of the severed limb battalion, he is a second-level soldier, and with his superhuman strength, he has already made Zuo Scar feel a lot of pressure, not to mention that he has 200 elite soldiers.

Taking a step back, even if the left mark can be defended, but so what, Thorde's purpose is the North Wind Mine, and the destruction of the severed limb camp is only incidental!

He could have occupied all the places except the severed limb barracks, and surrounded the severed limb barracks, what was the difference between the left scar and being destroyed at that time.

Of course, if you can't keep it, let alone the one behind.

【Ding! You have successfully improved the mines in the area and gained 4 skill points. 】

Four skill points, I didn't expect such a thing to have four skill points, not bad.

Left Scar was obviously satisfied, and immediately added all four skill points to the primary high-speed cast.

Now that the iron ore matter is solved, then the supply of resources should barely be able to build a new building, for example... Training ground!

The training ground seems to need:

[Training Ground Construction Drawings, Level 1 Resources (300 Cedar Logs, 200 Iron Ingots, 100 Leather Strips) Level 2 Resources (50 Cedar Logs, 40 Stones, 10 Steel Ingots), requires 30 workers and 12 hours. 】

The training ground is divided into five parts, the first part is the training ground for hoplites, the second part is the training ground for light infantry, the third part is the training ground for shield soldiers, the fourth part is the training ground for archers, and the fifth part is the mixed training ground.

Not to mention anything else, just the hedge of the stone man formation of the hoplites, Zuo Zhen felt that this training ground was very necessary. What is the key to hoplites,

First: Break down the opposing formation,

Second: Don't be overwhelmed by the other side.

As for the real killing, that's the light infantry!

Look at the large wooden alley of light infantry, the chaotic environment requires light infantry to practice with wooden men in the wooden alley, this is definitely worth it!

Seeing these two parts, Zuo Zhen couldn't wait to build a training ground, which was several times better than Mo Lin's training method!

Take a look at your resources:

[1st grade (cedar log 1000, leather strip 600, iron ingot 200) second grade (stone 300, leather 100, cedar log 100, steel ingot 50)]

Now there are 500 people in the severed limb camp to become the labor force of Zuo Trace, and with these 500 people, plus two over-operated secondary material processing factories and an over-operated arsenal (the premise for solving the problem of iron ore mining), Zuo Trace has basically achieved sufficient use of resources. Of course, this means enough resources for the construction of the watchtower, the stone wall under construction, and the upcoming training ground.

That's a full 500 people, and after deducting 100 of them to maintain the operation, the remaining 400 can collect a full 2000 first-level resources and 500 second-level resources a day. If so many people can barely keep afloat, that's the real joke.
