When you arrive at the 'realgar mine' mining site, it is a relatively low terrain with a small hill on the left, and the surrounding terrain is generally flat.

It is 40 kilometers away from the town of Manbach, 5.8 kilometers away from the Zhenbei Iron Ore Field, 12.7 kilometers away from the Snowy Wasteland, and the nearest human camp nearby, the Zhenbei Iron Mine, the Snowy Wasteland Supply Station and the Seventh Monitoring Point Camp.

"Zhenbei Iron Mine" has the scale and number of miners, not inferior to the population of Manbach Town, and it is a big problem to eat, drink and Lazar every day, so on the ground, it has a miner base with a large area, people are not machines, it is impossible to stay in the mine all year round, do not eat, drink or sleep, and the miner base is where the miners rest.

Although the safety factor and material reserves are not as good as that of Mambach Town, after all, it is a gathering camp that supports 100,000 miners, and the scale will not be small.

But now it should be unmanned, and all the miners, including those in the miner base, have been slaughtered by the gold eater rat swarm.

The 'Snowy Wasteland Supply Point' is the last place to enter and exit the Snowy Wasteland in exchange for supplies, which is not under the jurisdiction of Manbach Town, but has a close connection with Manbach Town, with a resident population of two or three thousand.

The seventh monitoring point camp is an observation point set up by the regional lord, some people say that it is used to detect movements in the snowy wasteland, and some people say that it is used to monitor the town of Manbach, what is the specific purpose, maybe the Lord of Manbach will know, but ordinary people definitely do not know.

There are at least two Ironclad Cities, each of which is not small, and the town of Manbach is definitely in the top 100.

The most important thing is that the ironclad city of the seventh monitoring point is equipped with 'heavy artillery'.

The camp at Monitoring Point 7 does not have much contact with the surrounding area, except for occasional trips to the town of Manbach for procurement, and activities are carried out in the vicinity of the monitoring site at other times.

"It's cold!"

Standing on the deck of the 'Ancient Castle', Li Yinguang felt that the temperature outside should be almost below freezing, and the northwest wind was howling, so he couldn't help but shrink his neck.

The butler Goda said: "In a few days, it will be even colder, and after entering the winter, the whole world here will be covered with ice and snow, even during the day, the average temperature will not fall below minus forty degrees, and the time will last for several months." ”

Li Yinguang frowned and said, "Then can the Iron Armor City still start?" ”

"Yes, yes, it needs to consume more fuel." The butler Goda said helplessly in a low voice: "Master, fuel is a big problem for us, and it should be solved even more than the weapon system. Once the Castle runs out of fuel, even if it is not killed by the enemy, we will freeze to death in the wilderness! ”

Li Yinguang nodded: "Let's mine the 'male yellow ore' first, and when the collection is almost done, we will go to the western forest to cut wood." ”

Wood is the most primitive fuel, and at the same time, it is also the least expensive fuel. But the disadvantages are also obvious, first of all, the kinetic energy it provides to the smelting furnace is limited, and the wood-burning ironclad city can't 'run'. The second is that storing wood requires a lot of space, and even if the entire Iron City is filled, it can't support the smelting furnace for too long.

When there is no rut, the ironclad city lord will also choose wood as fuel to support it for a while.

The preferred fuel is 'black fuel', which is actually hard coal, which can provide a lot of kinetic energy and has a wide distribution area, but there are no large-scale black fuel mining areas around Mambach Town, they are all small minerals.

Secondly, there are 'Mystery Gems', 'Mystery Fuel', 'Mystery Ores', etc., all of which are treasures that can be thrown directly into the smelting furnace to become fuel.

In fact, anything incinerated in the smelting furnace can be converted into kinetic energy, which is nothing more than a matter of the size of the production conversion rate.

The 'space radar' detection showed that the 'male yellow ore' was more than ten meters away in front of the ancient castle, but it needed to be excavated about ten meters down.

It would have been much easier to install excavation equipment for the Castle, but the problem was that the Castle did not have those equipment, so it had to be excavated by machinery and personnel.

The Castle can provide light for those digging below, and the vantage point can monitor the surrounding movement and prevent accidents.

Excavation at night is not a very good choice, and mining here during the day is not a good choice.

At least the surroundings are safe now, and with Li Yinguang driving the 'space radar' on the Castle, there won't be any big problems.

It's just a bit fuel-guzzling!

Bucher organized the manpower to simply modify the vehicles that were suitable for modification and can be used for excavation, and then put them into excavation.

Li Yinguang's request is to dig as fast as possible, as soon as he sees 'realgar ore' immediately mining.

Strive to finish mining a few tons of 'realgar ore' underground before dawn, and then leave, leaving no chance for the tracker.

The excavation work went relatively smoothly, and after about an hour, the housekeeper Goda ran up with a piece of 'realgar ore' weighing dozens of catties in his hand.

Excitedly: "Master, I dug it!" ”

Li Yinguang, who was drowsy, suddenly came to his senses, squatted in front of the 'male yellow ore' and said while studying: "Pass my order, except for the necessary guards, everyone else will be put into the mining work, dig as much as you can, and we have to leave after dawn!" ”

"Yes!"

The steward Goda turned around and walked away quickly, although the price of realgar ore is not very expensive, it is not too cheap, and most importantly, the first time that the Castle has mined ore in the wilderness, it is the first time in history.

Li Yinguang put his hand on the 'realgar ore', and a cool energy was extracted from the 'mysterious gem' sewn in his heart from the realgar ore, but the 'realgar ore' did not change much.

The energy absorbed by the 'mysterious gem' sewn in the heart is the energy absorbed by the 'realgar ore' in nature, not the material energy of the realgar ore itself.

To put it simply, after being absorbed by the 'mysterious gem' sewn in the heart, the 'realgar ore' can still be used as a 'realgar ore'.

Li Yinguang can't say what theory, but he knows that the 'realgar ore' in his hand can still be refined.

Just like the pinecone-shaped 'Iron Eater Nest', although it has been devoured and absorbed by the 'Mysterious Gem', it still exists, and it can continue to be used in the same way.

However, after the 'Mutant Black Fuel' was absorbed by the 'Mysterious Gem' sewn in his heart, it turned into a pile of scum and could not be used again.

Maybe it's because the 'mutated black fuel' has directly turned into 'energy' and entered the 'mysterious gem' sewn in the heart for storage.

These 'energies' can be directly used in the Iron City, which is equivalent to the conversion of the 'smelting furnace' into kinetic energy, so there is no need to be there.

Or the 'Mysterious Gem' sewn in his heart, what he absorbed was an energy that Li Yinguang couldn't understand, anyway, after being absorbed by it, whether it was the 'Iron Devouring Worm's Nest' or the 'Realgar Ore', it could still be used.
