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

"Elder Feng, do you know them?"

Lu Zaian scrutinized the two assassins; their skin was pale and bloodless, and their faces were remarkably identical.

They look as if they were carved from the same mold.

Elder Feng stroked his beard and nodded, saying:

"Indeed, these two are the Twin Demons of the Netherworld."

It is said that these two brothers are proficient in a secret technique of combined soul attacks, and often appear on the outskirts of the marsh to ambush and kill cultivators in the early to mid-stages of Qi Refining...

I never expected to end up here.

Why are they targeting you, Master Lu?

Lu Zaian pondered for a moment, then sneered.

"Why don't you just ask them and you'll find out..."

A water balloon hit their faces, and they slowly woke up.

The Twin Demons looked around and discovered that they had been placed under a restriction, rendering them unable to move. Their expressions changed drastically.

"How did you find us?" x2

The Twin Demons spoke in unison, staring intently at Lu Zai'an.

They used treasures to bypass the cave's formations and hide inside, without even the people of Cuiwei Pavilion noticing.

They had planned to ambush Lu Zaian, but instead they ended up getting trapped and beaten...

Wasn't the ambush target supposed to be a frail old alchemist?

That terrifying attack just now, anyone who didn't know better would have thought it was unleashed by a cultivator at the peak of the ninth level of Qi Refining.

"I should be asking you this: we have no grudge against each other, so why did you ambush me in my cave?"

Lu Zaian asked back with a sullen face.

The Twin Demons exchanged a glance and remained silent.

If caught, death is the only outcome.

Having committed murder and arson for so many years, they knew that one day they might get their comeuppance.

I just didn't expect it to come so suddenly. I regret being greedy for those spirit stones...

"You won't talk? I was originally thinking of handing you over to the city guards."

"Since that's the case, then die! Trespassing into the cave, killing you all won't get you any blame."

As he spoke, Lu Zaian was about to raise his hand.

"and many more!"

Upon hearing this, the Twin Demons suddenly felt a glimmer of hope for survival in their eyes.

If someone breaks into another person's cave and commits violence in the desolate city, they should not be executed if they are captured and detained.

There are several spirit stone veins in the waters outside the city that are short of miners, and they are usually sent to mine in the veins.

Sentences range from thirty to one hundred years...

Although the marshes were teeming with poisonous insects and miasma, and teeming with monsters, most miners did not live to see the end of their sentences.

But it's better than being killed right now.

"We have no grudge against you. Someone paid us brothers with spirit stones to commit this crime!"

"Oh? Who is it?"

"A guy at the eighth level of Qi Refining, his face was hidden under a bamboo hat, but he seemed to be quite muscular."

The Twin Demons spoke truthfully.

"How much money did he give you? And how will you contact him after the deal is done?" Lu Zaian asked.

"We paid a deposit of one thousand spirit stones, and there will be another two thousand after the deal is done. The other party only told us to use this compass to receive messages, and we cannot contact them on our own initiative."

The lives of the You Sha Twins are now entirely in Lu Zai'an's hands, so they have no choice but to explain.

They pulled out a black compass.

The compass was engraved with dense patterns resembling mosquitoes and flies, emanating a mysterious energy.

Lu Zaian understood at a glance.

Tracking array pattern, echo array pattern, spell-breaking array pattern...

This is a first-tier, low-grade array plate.

It can track auras and transmit sounds at close range, and also has the ability to break through first-tier low-grade formations.

Lu Zaian sneered: "You used this array plate to quietly open the array outside the cave, didn't you?"

Unfortunately... this array plate is only a low-grade first-tier item.

He had also secretly set up another mid-grade illusion array in his cave, and the Netherworld Twins fell for it.

Lu Zaian's mind raced, and he secretly began to guess...

However, given the sensitive nature of the matter, Lu Zaian said to the two people beside him:

"Elder Feng, shopkeeper, I still have some questions for these two people, you..."

Elder Feng and the shopkeeper immediately understood.

"Haha, if Master Lu has any needs, he only needs to call us."

After saying this, the two left the cave.

In the outside corridor.

The shopkeeper sighed and whispered to Elder Feng.

"Elder Feng, I think that Master Lu is really not simple..."

Elder Feng nodded.

Surprisingly, he, a cultivator at the peak of the ninth level of Qi Refining, actually felt an inexplicable pressure when Lu Zaian made his move.

"Indeed, this person is proficient in alchemy and his magical power is more abundant than that of other cultivators of the same level. I heard that he has only been in Huangze City for a year, but he has already made a name for himself. If given time, he may be able to break through to the Foundation Establishment stage."

Elder Feng seemed to remember something, and then gave another instruction:

"Our guest was assassinated inside the cave, and we at Cuiwei Pavilion are in the wrong about this."

Go prepare some spirit stones and apologize to him later.

We must not antagonize such people.

"……Yes"

Inside the cave.

Lu Zaian snatched the array plate from the Netherworld Twins, infiltrated it with his magic power, and after sensing it for a moment, let out a cold laugh.

"They're quite cautious. It seems they've realized they've already failed?"

Just now, the tracking and echo array patterns within the array plate were unilaterally severed.

Ordinary cultivators would have no way of tracing the origin of this array plate.

But Lu Zaian is no ordinary cultivator.

He was already a genuine mid-grade first-tier array master.

"The array patterns on this array plate are crooked and twisted, and many of the connecting nodes are obscure. The maker must be no more than a first-level low-grade array master."

Lu Zaian only needs to reverse the array patterns to track the target in reverse...

Before that, Lu Zai'an looked at the two You Sha twins beside him, who looked utterly hopeless.

The two of them had already told Lu Zaian all the information they could.

Now all I can do is anxiously await my fate.

Lu Zaian stroked his chin, pondering whether these two still held any value for him, when suddenly an idea struck him.

"I've heard you're skilled in soul magic? Where did you learn it?"

The Twin Demons exchanged a glance, revealing a strange yet relieved expression.

"What's your expression?"

Lu Zaian was puzzled, his face darkened, and he questioned her.

"No, Master Lu, it's just that our soul-secret technique is not actually a secret..."

"Hmm? How so?"

The Twin Demons had no choice but to offer an explanation...

After a while, Lu Zaian finally understood the reason.

It turns out that this happened as early as ten years ago.

At that time, the twins had not yet made a name for themselves as the "Ghostly Twins".

They stumbled upon this set of soul-secret techniques in a deep swamp in a desolate marshland.

The news spread like wildfire.

Soul-binding techniques are incredibly precious, which is why they are coveted by countless cultivators…

Among them are many major foundation repairs and renovations.

Even the Core Formation City Lord who was stationed in Huangze City was quite interested in this.

Forced by this overwhelming situation, the two brothers had no choice but to obediently hand over the secret technique of the soul.

Strange to say.

Logically speaking, the more profound and unfathomable a martial arts manual is, the more difficult it is to decipher its mysteries.

Such secret techniques are basically unique copies, and it should be very difficult to make copies.

However, the two brothers could freely copy the soul technique they obtained without any restrictions.

Even dungeons can be expanded into new dungeons, seemingly with an infinite multiplication effect...
