Soul Searching

In the dark canyon, the soul of the beautiful woman who controlled ghosts was completely enveloped by the eerie green flames of the Poison Demon, emitting a series of shrill screams.

The Poison Demon completely refined the soul of the Ghost-Controlling Beauty, and also Poison Demon the soul of the Million-Year Ghost King.

In an instant, Yi Yun felt the power of the Poison Demon rapidly expanding, its body becoming more solid, as if it were a physical entity.

The Poison Demon has existed for hundreds of millions of years. In such a long time, its growth has been extremely slow, and it has never experienced such a leap in strength. Absorbing the immense power brought by the Million-Year Ghost King made the Poison Demon feel comfortable all over, and it couldn't help but look intoxicated.

"Hahaha, what powerful strength!"

The Poison Demon laughed loudly. It suddenly realized that although it had been forced to sign the Soul Contract, following Yi Yun seemed to be a good choice. If it were on its own, it would be difficult to get such an opportunity to leap in strength.

"The rest of them swallowed it too!"

Yi Yun spoke up, saying that at this moment, only three people remained in the Danxin Sect. The most powerful, the black-faced middle-aged man and Su Boyang, had their meridians destroyed by the old snake and were powerless to resist. As for Su Muyan, he was even less capable.

"Thank you for your kindness, Master!"

Upon hearing Yi Yun's command, the Poison Demon let out a wild laugh. This was practically a feast delivered to it. It immediately split its body into three, transforming into three balls of green flame, which flew towards the three of them.

"You little beast, the Danxin Sect will surely skin you alive!"

Su Boyang unleashed a frantic curse, but his venomous voice was quickly extinguished by the green flames, turning into a shrill scream.

"You... you will all... die a horrible death!"

Su Boyang's voice was distorted, but he was still yelling wildly.

"You old bastard, since you're so good at yelling, I'll let you yell a little longer."

The Poison Demon chuckled and said that at this moment, the souls of the three people were all under its Poison Demon. It could torture them however it wanted. If these people had simply died obediently, it would have refined them directly.

But for someone like Su Boyang, who utters harsh words even on his deathbed, it will give him a "special treatment," making his death even more painful.

The pain that comes from the soul is many times more intense than being torn apart by a thousand cuts.

Soon, Su Boyang completely collapsed. His Spiritual Sense was shattered by the pain, let alone being able to continue shouting.

"What did you find?" Yi Yun asked.

"In reply to Master, these are just fragments of memories, not complete. Whatever Master wishes to know, I will search and verify for you."

These soul fragments were in disarray; they had simply been sealed away by the Poison Demon. It wouldn't be something that could be processed and digested in a short time.

"I want to know the origin of the Danxin Sect's heritage, the core formation of the Medicine God Cauldron, and a medicinal herb called 'Undying Grass'."

Yi Yun asked the questions, these were the questions he cared about most, especially the "Undying Grass," Yi Yun was very interested in.

Following the directions given by Yi Yun, the Poison Demon searched carefully and quickly informed Yi Yun of all the results. Because of the existence of the Soul Contract, the Poison Demon could share this information with Yi Yun with just a thought.

However, the memories obtained from Soul Searching were too fragmented, making it impossible to obtain the complete inheritance. Yi Yun could only confirm that the Danxin Sect's inheritance originally came from the relics left by the Medicine God in Guixu.

However, the Danxin Sect does not rely entirely on the inheritance of the Medicine God. In the tens of millions of years of its development, the Danxin Sect has acquired more and more inheritances, some of which are ancient and have even filled in the gaps in the Medicine God's Classics texts.

For example, the cultivation of "Undying Grass"!

The Medicine God didn't study "Undying Grass" in great detail at the time; he only believed that the herb was extremely rare and difficult to cultivate artificially.

However, the Danxin Sect found a way to refine the "Rejuvenation Pill" on a large scale. Unfortunately, the Danxin Sect's formula had serious flaws, which prevented them from making full use of the "Undying Grass".

In addition, Danxin Sect has collected some books on the core formation of the Medicine God Cauldron over the years, and even obtained fragments of the Medicine God Cauldron. If Yi Yun can obtain these books and fragments, he may even be able to repair the Medicine God Cauldron.

"This Danxin Sect truly possesses many ancient traditions. If I could obtain the Danxin Sect's inheritance and complete some of the incomplete parts of the Medicine God's Classics, it would allow my alchemy skills to advance further."

Yi Yun muttered to himself, glancing at the old snake unintentionally.

But this one glance made the old snake extremely wary.

"Kid, why are you looking at me like that? You don't happen to have your eye on the Danxin Sect's stuff and want me to be your henchman? I'm warning you, don't get your hopes up. I may have killed a few Danxin Sect elders, but who knows what kind of power the most powerful old monster behind the Danxin Sect is? Even if he can't beat me, I don't want to get involved. Fighting him would just waste my lifespan. Don't even think about trying to take advantage of me."

Old Snake quickly made his stance clear to Yi Yun; he was the kind of person who wouldn't act until he saw a clear benefit.

Yi Yun stroked his chin and said slowly, "Didn't you hear me ask about the Undying Grass? It's a kind of Longevity Pill. If I could obtain a large quantity of Undying Grass, I could mass-produce this Longevity Pill. I was thinking of giving you a hundred or so, but it seems you're not interested..."

"What? Longevity Pill!?"

The old snake's eyes widened. If there was anything in this world that could attract the old snake the most, it would definitely be the methods to prolong life and repair one's foundation.

Normally, the two are the same thing to the old snake.

"Is there really such a thing? And it can be mass-produced? You're not kidding me!"

The old snake knew that any elixir involving longevity and repairing one's foundation was extremely expensive, as the limitation of materials made large-scale refining almost impossible.

Yi Yun said, "'Large-scale' is relative. Even with 'Undying Grass,' the cost of refining it is very high. Moreover, these Longevity Pills are most effective when taken initially, and their effects diminish over time."

Yi Yun truthfully stated that any elixir, if taken continuously, would become less and less effective, but this was not a problem for the old snake at all.

The old snake clapped his hands. "Kid, tell me, what do you want me to do?"

Hearing the old snake's words, Yi Yun rolled his eyes. This old man was too direct.

"Let's collect the bodies first, then we'll talk back in the city!"

Having just killed so many people from the Danxin Sect, Yi Yun didn't want to linger here, lest reinforcements from the Danxin Sect arrive, which would cause trouble.

"Good."

The old snake immediately released several fireballs, burning all the corpses to ashes. Then, a gust of wind blew, and all the ashes vanished without a trace of blood. As for the traces of the battle, they were completely erased by a few casual punches. It seemed that the old snake was already very skilled at cleaning up the battlefield.

"Let's go back to the city."
