I have a forging furnace.

Chapter 19 Iron Skin
After passing through the formation, a dark cave appeared in front of everyone.

The entrance to the cave was very large, and many civilians were coming in and out carrying black iron crystal ore.

The cave is surrounded by a circle of low wooden houses, most of which are crudely designed and have only simple functions of sheltering from wind and rain. There is only one elegant wooden house standing alone in a corner.

At the door of the elegant wooden house, a middle-aged monk waved at Lin Yu and the other three.

It should be the previous garrisoner.

Lin Yu approached and showed his outer disciple token and mission documents. The middle-aged monk smiled happily: "Great, I can finally leave this damn place."

"Brother, is this place dangerous?" Lin Yu's face froze.

"No no."

The middle-aged cultivator waved his hands quickly, fearing that he would scare Lin Yu away. "It's just that it's too boring to practice in the mountains for a month. I can't stand it any longer."

"I see." Lin Yu's brows relaxed. If it was just because of this, it wouldn't be a big problem for him.

He is a quiet person by nature, and would feel uncomfortable in a place that is too busy.

Next, the middle-aged monk took Lin Yu to understand the basic situation of the iron crystal vein, and introduced the miner manager of the vein to Lin Yu.

Lin Yu took over the authority of the formation, and the middle-aged cultivator happily packed his luggage and left this place that made him feel depressed.

The miners are all mortals, recruited locally by Xuanyang Sect. They signed a contract to sell their entire lives to Xuanyang Sect, while the person in charge of the miners is a high-ranking member of Xuanyang Sect.

Not everyone in the family of a high-level cultivator has spiritual roots, there will always be mortals.

With this background, although the strongest defenders on the mine are nominally like Lin Yu, the profits of this mine are all in the charge of the miner managers.

The miner manager of the Tiejing Mine is named Ji Chengyu, and Lin Yu has no idea about his background.

On the surface, he was very respectful to Lin Yu, but Lin Yu could feel that this guy didn't take him seriously at all.

Come to think of it, the garrison is changed every month, and outer disciples cannot serve as garrison in one place continuously. Ji Chengyu didn't know how many outer disciples he had met.

Without respect, there will naturally be no commission.

Thinking of this, Lin Yu suddenly chuckled.

Yes, if he could get a commission from the resources of a place by garrisoning there, then he would not be given the chance to take on such a garrison mission.

As expected, for most outer disciples, garrison duty meant going to jail.

Fortunately, Lin Yu is not going to jail.

The next day, Lin Yu communicated with Ji Chengyu and then went down to the mine with a pickaxe.

Tang Mai and others wanted to follow him, but were all rejected by him.

"This outer sect disciple shouldn't be short of spirit stones, so why is he going down to the mine to collect spirit stones himself?"

Ji Chengyu was a little confused.

The sect stipulates that all ore collected by miners must be handed over to the sect, but it does not say that ore collected by stationed disciples needs to be handed over.

Many disciples are aware of this loophole in the system, but only a few who are so poor that they can barely make ends meet would go down to the mines themselves.

After all, you may not earn a single spirit stone after working hard for a whole day. For most disciples, this is not necessary at all.

Lin Yu came with his family, and he didn't look like the kind of guy who didn't have spirit stones, so Ji Chengyu felt a little strange.

But he soon forgot about the matter. As long as these stationed disciples did not cause any trouble and did not ask for any commission, they could do whatever they wanted and he had no right to interfere.

The iron crystal mine cave was connected in all directions, and Lin Yu randomly chose a direction to walk in.

When the miners along the way saw Lin Yu dressed as an outer sect disciple, they immediately straightened their postures and greeted him respectfully, "Hello, Immortal Master."

Lin Yu nodded casually and ignored him.

As we went deeper, the air became increasingly turbid and the number of miners mining became fewer and fewer.

Lin Yu found an deserted area and dug with a pickaxe. He easily dug up a large amount of rock and exposed the iron crystal ore.

Compared to chopping down a first-level copper tree, mining is so easy. Especially now that Lin Yu has the copper bones and the perfect Bull Demon Power, his physique has been trained to a level that he doesn't even know.

Iron crystal ore is black and shiny all over, and is very easy to identify.

Lin Yu placed his hand on the iron crystal ore, and a prompt appeared in front of him:
[Material: Iron Crystal Ore]

[Level: First Level]

[Quality: Medium]

[Evaluation: Natural ore condensed from iron crystal veins]

[Refining Gain: Iron Skin Fragment]

[Do you want to start refining? ]

Iron-boned and iron-skinned?

They are generally not made of iron and steel, Lin Yu complained in his heart.

However, this gain is the direction he really wants to see.

The physical changes brought about by the bronze bones brought great benefits to Lin Yu.

Now I don’t know what benefits this iron skin will bring.

Refining.

Iron Skin (1/100)

At the same time, Lin Yu felt that his muscles were a little stronger than before.

After possessing bronze bones and practicing the Bull Demon's Great Strength Skill to perfection, the handsome young man he was when he first started had disappeared.

Lin Yu now has a streamlined figure with well-defined muscles. If he were not usually covered by the loose outer disciple uniform, he would have attracted countless senior and junior sisters.

Keep up the good work!
Feeling the changes in his muscles, Lin Yu was full of energy.

After a few bangs of the pickaxe, a deep mine was dug out.

That night, Lin Yu, wearing a clean and refreshing Taoist robe and looking as if nothing had happened, walked out of the mine calmly.

Behind several rows of wooden houses, a dense forest was also framed within the formation.

This is a rare hidden place in this mineral vein. This was told to Lin Yu by the previous middle-aged cultivator. When the middle-aged cultivator was bored during his training, he would practice magic here for a while.

Now it’s just right for Lin Yu to use.

While Lin Yu was mining, Tang Mai and the other two were not idle either. According to Lin Yu's instructions, they cleared out a small clean area in the woods and placed an alchemy furnace on it.

They also cut down trees to make wooden blocks and inserted them around the area to create a cover to prevent the miners from prying eyes.

Lin Yu was very satisfied when he saw the alchemy furnace and the firewood prepared below.

During the alchemy process, Tang Mai and the other two did not receive any instructions from Lin Yu, so they did not watch.

It’s not that Lin Yu doesn’t want to teach, but their cultivation level is not high enough.

At the very least, you need to reach the Qi training level and have your own spiritual power in your body before you can teach. Otherwise, teaching is a waste of time.

Lin Yu took out the prepared materials and put them into the alchemy furnace one by one.

The Rejuvenating Pill is a pill with a very high profit ratio. The material cost of one spirit stone can bring a profit of fifty spirit stones.

It is more profitable than refining other first-level elixirs.

This is closely related to its difficulty. There are very few first-level alchemists who can refine the Rejuvenating Pill, and there are not many second-level alchemists who can do it. Even if they can, those people's attention is focused on the second-level pills.

This has led to a market where first-grade anti-aging pills are in short supply.
