Duke urgently needs a large amount of magic metal to enhance his strength. The yellow sand inside the yellow sand crystal can devour various magic metals to improve the quality of the sand.

However, magic metals are expensive, and the price of any kind of magic metal is not cheap.

Duke had previously looked up some relevant information and found that the general price for magic metals is twenty magic stones per pound.

It seems not particularly expensive, and he can afford to buy some.

But the key is, Duke needs a large amount, and just a few pounds of magic metal is far from enough.

When he conducted tests in the laboratory, he calculated that he needs at least five tons of yellow sand to sustain daily combat operations.

This means that Duke needs to devour at least five tons of magic metal to enhance the quality of the yellow sand, which translates to a full two hundred thousand Level 1 magic stones.

For Duke now, two hundred thousand magic stones are an astronomical number, and even making magic potions every day would take an unknown amount of time to gather.

And these two hundred thousand magic stones are only enough to improve the quality of five tons of yellow sand, barely meeting basic combat needs.

If it involves larger-scale battles and magic spells, like Duke has envisioned, manipulating hundreds or thousands of tons of yellow sand against enemies, the magic metal consumed would again be an astronomical number.

Currently, he certainly can't manipulate such a massive amount of yellow sand, but once he becomes an Official Wizard and his power gradually increases, he will naturally reach this stage.

But even if he achieves this, he still needs a vast amount of magic metal to support the strength of the yellow sand.

Just five tons of magic metal is already unaffordable for Duke now, let alone hundreds or thousands of tons, which he can only imagine.

After arriving at the Beastman Plane, Duke naturally targeted the rich mineral resources there.

Only here might he obtain a large quantity of magic metal at a relatively low cost.

...

At dawn, Duke and his group were walking through the wilderness outside Moon Shadow City.

This team was led by Master Land, followed by six Official Wizards, as well as Duke and five other Wizard Apprentices.

In addition, there was a Slave Legion following behind them, totaling over sixty slave creatures.

The strongest among the slave creatures was a kobold named Reid, with Level 1 Peak power.

Their task was actually to do some miscellaneous work and, incidentally, to protect Duke and the other wizard apprentices.

Land and the others didn't need protection from these slave creatures; having them follow was entirely for the benefit of the wizard apprentices.

In the squad, there was also a green-skinned orc following, an orc named Colin.

He had already been marked with the Slave Mark and was now responsible for leading Land and the others to a nearby already-exploited mining area.

Colin's expression was complex; he naturally harbored extreme hatred towards these outsiders.

But ever since being marked by the Slave Mark, he could no longer feel hatred towards the wizards in his heart.

This left him deeply conflicted, with a strong sense of dislocation. The Slave Mark made it impossible for him to even feel hatred, at least not towards the wizards.

The mining site closest to Moon Shadow City was under exploitation but had been halted due to the sudden outbreak of war.

Duke and his group soon arrived at this mining site located in the mountains, surrounded by evident traces of mining, as well as numerous mining carts and special drilling tools and other equipment.

The Beastmen race was also skilled in craftsmanship, producing many peculiar tools that were extremely convenient for mining stones.

Master Land casually picked up a stone from a mining cart, holding it in his hand and continuously examining it.

This was just a primitive ore; a series of complicated smelting processes were necessary to obtain Golden Scale Celestial Iron.

"A very fine piece of magic metal. Let me think, many alchemy creation formulas can be altered…" Master Land then started conversing with the people behind him.

Those people were either students of Master Land or his colleagues, all skilled in alchemy.

Duke also picked up a piece of ore from the ground, remembering the appearance and characteristics of the Golden Scale Celestial Iron.

The piece of ore he picked up was only about the size of a fist, and not much Golden Scale Celestial Iron could be refined from it, so naturally, he wouldn't absorb it in front of everyone.

Duke casually placed the ore into his Space Ring, and no one would comment on this, as taking a sample back for research was quite normal.

As the mining site was not yet under the management of Black Sail, picking up some ore randomly was not an issue.

Most of the wizard apprentices around were doing just this; some even directly placed a huge stone weighing at least two tons into their Space Rings.

Duke even suspected that if their Space Rings weren't too small, they might try to take an entire mining site clean.

That's also one of the reasons Wizard Organizations allow wizards to take resources from other planes; the amount an individual can take is really too little.

Duke glanced at the yellow sand crystal on his left arm, thinking to himself, "Hope I can find an opportunity…"

For him, as long as he had enough time, he could even scour clean all the ores on this entire plane. The magic metal that the yellow sand crystal could devour was virtually limitless.

Subsequently, the group slowly delved deeper underground along the already dug tunnels. Master Land needed to conduct a thorough investigation of the geological environment here to better perfect the information related to the Golden Scale Celestial Iron magic metal.

Master Land already had plenty of ideas in mind, feeling that maybe once he goes back, he could acquire some Arcane Master points.

He was currently a Level 3 Arcane Master, which was one of the reasons for his high status.

The credentials of a Level 3 Arcane Master are even more significant than those of a Level 3 Wizard, crucial for a wizard's faction, providing immense value.

Master Land seemed very interested in the geological environment here, keen on further exploration underground.

However, the mine passages below were not stable; it didn't matter much to Land and his peers, but it could pose a danger to Duke and the other wizard apprentices.

After thinking for a moment, Master Land said, "You guys go and explore nearby to see if there are any other mineral veins. Take those slave creatures with you, but don't go too far."

That was actually the purpose of their visit, to identify the locations of some mineral veins, which would facilitate future mining.

Finding a mineral vein could earn them a substantial amount of contribution points, which was also an opportunity given by Master Land to the young ones, depending on whether they could seize it.

As for safety, he wasn't too worried. Most of the nearby Beastmen forces had been cleared out; even if there were remnants, they were merely stragglers.
