Immortality and Cultivation: This old man seeks enlightenment through mere survival.

The words fell.

Suddenly, Lu Zaian released his divine sense, drawing upon the [Small Yin Yang Creation Array] spanning a radius of three hundred miles!

His own divine sense was only enough to cover 15 miles, and it would be very difficult for him to penetrate hundreds of feet underground.

After all, the pressure increases dramatically with every inch that the divine sense penetrates underground.

However, by taking advantage of the mountain-protecting formation, connecting the mountains and terrain, it can be done easily.

boom! ! !

In an instant, a large array of black and white colors appeared like a yin-yang jade bowl, and fell down as if the sky were collapsing!

"The Calamity of Ghosts, Illuminating Heaven and Earth!"

Lu Zaian gave a soft shout, his eyes flashing with a deep, unfathomable light.

A torrent of divine consciousness surged forth, connecting with the array.

Full power!

The entire Yunli Mountain, and even the surrounding mountains and rivers, trembled and shook.

The people in the mountains were all terrified and quickly braced themselves with their feet to steady themselves.

"Hiss... What a terrifying formation!"

"The mountain lord's strength seems to have increased even more..."

Even though the people from the Crimson Forging Immortal Workshop were already familiar with the existence of this mountain-protecting formation, they were still aware of it.

But seeing it in full operation now still makes me gasp in astonishment.

What terrifying power is this?!

Perhaps even a Core Formation cultivator's strength is only this much?

The entire area, spanning a thousand feet on the ground, was swept by Lu Zaian's immense divine sense.

Snakes, insects, rats, and ants had nowhere to hide and fled in panic!

Lu Zaian followed the loose ore along the fissure in the earth's fire and tracked it all the way.

Half an hour later, traces of a mineral vein were finally discovered two hundred miles away.

"Found it! This is it?!"

Through divine sense, deep underground, thousands of feet below, the light was dim and weak, with only a few flickering lights appearing and disappearing among the rock layers.

However, when Lu Zai'an looked closely, he was surprised to find that these flames were not ordinary lights, but came from densely packed fire poison crystals.

These fire poison crystals are like gems embedded in the rock strata, emitting a faint but persistent light.

They are either large or small.

Some are the size of a fist, while others are only the size of a fingernail.

Without exception, they all shimmered with a chilling red light.

As the firelight flickered, Lu Zaian seemed to see the breath that had continued from the ancient earth veins to the present day.

The aura emanating from these fire poison crystals was exceptionally rich, like a surging river of lava flowing endlessly in the underground world.

"Such a scorching aura of fire poison!"

Lu Zaian frowned slightly.

Even with his powerful divine sense, which only lingered on the ore vein for a moment, he felt a burning sensation.

It strikes right at the soul!

If I hadn't personally witnessed Su Xuanhuo and the others forging the fire poison crystal ore into elixirs...

Lu Zaian really couldn't believe that this Fire Poison Crystal Mine was beneficial to cultivators.

"This is not the main mining location; the ore veins continue all the way to outside the great formation."

"There might be fire poison crystal mines buried beneath the Changli Mountains, which stretch for tens of thousands of miles..."

Looking at this endless stretch of mineral layers.

Even with Lu Zaian's current composure, his heart couldn't help but pound wildly.

"If this rich mine were fully mined, it would be worth millions of spirit stones..."

"Phew... Calm down, I have to calm down!"

Lu Zai'an silently circulated the "Ghostly Netherworld Tribulation" in his mind to calm his mind.

At the same time, we are also thinking of countermeasures.

Resources worth millions of spirit stones, once exposed.

It is likely that all Foundation Establishment and above forces in the entire Northern Sky Domain, plus the Liushi Domain, will be alarmed.

At that time, Changli Mountain will become the target of everyone's attacks.

“Mining will definitely cause some noise, but I can conceal my presence within the formation.”

However, the array's range was still insufficient; compared to the vast mineral layers, it only covered less than a hundred miles..."

Lu Zaian pondered for a moment.

"It seems we can only mine a small portion of the formation first."

The rest can be dealt with gradually as the grand formation extends further.

Or, once we have enough strength, we can mine openly and legitimately…

Having made up his mind, Lu Zaian marked the spot with array patterns, and then withdrew his divine sense in an instant!

In mid-air, his figure slowly floated down, and Su Xuanhuo and the others surrounded him.

"May I ask, Master of the Mountain, have you gained anything?"

Su Xuanhuo dared to ask.

Lu Zaian remained silent for a long time, looked around at everyone, and slowly uttered a single word.

"Have."

Actually, he had a fleeting thought just now.

Just in case, they killed everyone from the Crimson Forging Immortal Workshop except Su Li, and searched their souls to obtain the methods of mining and alchemy.

Then keep this secret and proceed slowly on your own.

However, Lu Zaian quickly dismissed the idea.

These people are invaluable assistants.

In these mountains, Lu Zaian is the absolute ruler.

As long as the great formation covers the area, the lives of everyone, whether to kill or not, are entirely up to him.

It's better to keep them to do the work for you.

With strict supervision and a system of rewards and punishments—a carrot and a stick approach—they will surely understand what to do.

Having thought this through, Lu Zaian slowly said:

"It's over two hundred li to the southeast, a thousand zhang underground. I've left array markings along the way. You can lead people to find them, set up mining sites, and refine spiritual pills."

Upon hearing this, Su Xuanhuo's eyes lit up, and he immediately bowed respectfully.

"I will certainly not fail the mountain lord's trust!"

Lu Zaian then said calmly:

"The underground mineral deposits are complex and intricate. I will dispatch more people to assist you and set up multiple layers of formations, both for protection and monitoring. Do you understand?"

The manpower of the Crimson Forging Workshop alone is definitely not enough.

Lu Zaian planned to have Xu Yan'er invite the Xu family to mine together during the off-season in Lingtian.

In addition, a batch of golems specifically designed for mining were crafted.

In this way, we will have enough manpower.

It can also serve as a means of mutual supervision.

"Understood! Understood!! The idea of ​​using scattered ore to forge pills was entirely my own. I beg the Mountain Lord to punish me!"

Su Xuanhuo's expression changed slightly, filled with fear and trepidation. He knew that the mountain lord was giving him a warning for the disciples' previous dishonest use of Yang Yuan Pills.

The disciples of the Crimson Forging Immortal Workshop standing nearby trembled upon hearing this and quickly bowed their heads to apologize.

Su Li gritted her teeth and stepped forward, saying in a sweet voice:

"Mountain Lord, please don't blame my grandfather. It was all Li'er's idea."

The Crimson Forging Immortal Sect was destroyed by the Burning Palace. The disciples, driven by a thirst for revenge and an urgent need for elixirs and spirit stones for cultivation, were forced by circumstances to resort to this desperate measure.

What Su Li said was true.

The spiritual energy in Yunli Mountain is scarce, and the disciples of Chiduan Immortal Workshop do not receive many alchemy tasks.

Therefore, the monthly offering of spirit stones is naturally not much.

That's why they started eyeing the Fire Poison Crystal Mine.

During this time, Su Li and others also considered reporting the matter to Lu Zai'an to ensure fairness.

However, Lu Zaian was in seclusion at the time, so the matter was put aside.

Upon hearing this, Lu Zaian waved his sleeve, lifting everyone up. His expression softened slightly, and he said:

"Past events will be forgiven, and I will certainly not treat you unfairly in the future when you mine and refine pills."

But remember, everything on this mountain is yours to take, but if it's not yours... you can't even think about it.

Otherwise, don't say you weren't warned.

The Fire Poison Crystal Mine is a matter of great interest.

If it were just some loose ore that he embezzled, that would be fine, but he didn't want to see anyone touch the concentrate.

Therefore, it is important to make it clear in advance to avoid resorting to violence later.

Lu Zaian didn't consider himself a heartless person, but alas, the path to immortality sometimes required a certain ruthlessness.

"Yes, yes, yes! Thank you for your mercy, Mountain Lord! We will certainly obey your orders!"

Su Xuanhuo and the others nodded in response, but a cold sweat had broken out on their backs.
