Chapter 248: A New Gu Poison

Chapter 248: Chapter 248: A New Gu Poison

Should the oath ever be violated, this brand would instantly awaken and transform into intense negative emotions like regret, fear, and pain. It would constantly assault the Cultivator’s mind, like being plagued by a Heart Demon.

In this state, a Cultivator would be completely unable to continue their Cultivation. Forcing it would only lead to qi deviation.

Furthermore, a Cultivator who violates a Heart Demon Oath would have to directly confront the Heart Demon in the depths of their soul. This Heart Demon would very likely materialize, becoming a massive obstacle on their path. It would constantly erode the Cultivator’s sanity and Cultivation, making it impossible for them to focus on training. It could even cause their Cultivation to regress and their Realm to fall.

Her willingness to swear this oath was enough to make her position clear.

This meant Wuji Fairy absolutely did not dare to make an enemy of the two of them.

It seemed the actions of Jiang Xu and his companion had thoroughly cowed this Witch.

Zong Ziqi was one thing; that Killing Move of his had left even Jiang Xu shaken.

As for Jiang Xu, he had successfully killed Young Master Ghost, imprisoned her for a month, and could kill her with a single Seven Injuries Palm that shattered her Defense. All this terrified her even more.

"So? I’ve sworn the Heart Demon Oath, so I’ll definitely help you. You should let me go now, right?" Wuji Fairy asked, looking at Jiang Xu after she finished.

"True, I will let you go, but not right now. You Demon Cultivators are insidious and cunning, so we must be on our guard. Brother Zong, please wait here for a moment."

After Zong Ziqi nodded, Jiang Xu walked to another secluded spot, away from Wuji Fairy.

The Heart Demon Oath had indeed dispelled most of Jiang Xu’s concerns, but he still felt it wasn’t foolproof. He decided he needed to add a little something extra for Wuji Fairy.

As for what that "something extra" was...

Jiang Xu took the Golden Silkworm Gu from his Spirit Pet Bag.

Aside from using it once against a Demon Wolf, Jiang Xu had never put this creature to any other use.

This time, Jiang Xu planned to use it to concoct a poison for Wuji Fairy.

But first, Jiang Xu collected as much of the Golden Silkworm Gu’s current poison as he could.

He would soon be heading to the Demon Spirit State, a land teeming with Demon Beasts and Spirit Beasts. A poison that specialized in killing Demon Beasts was something he had to hold onto.

Fortunately, Jiang Xu had been collecting some of the Beast Gu Poison from time to time, so he already had a small supply on hand.

The quantity wasn’t large, but it was enough for quite a few uses, so he didn’t have to hesitate too much about changing the Gu poison’s properties.

’Hmm, the poison for Wuji Fairy... It should cause periodic flare-ups over a long period of time, and it has to fill her with dread.’

After a moment of thought, Jiang Xu reached for his Storage Bag, sensing the Spirit Medicines and Spiritual Materials within to judge which would be most suitable.

In truth, ever since obtaining the Golden Silkworm Gu, Jiang Xu had paid special attention to various poisonous herbs and toxins.

He had bought a fair number of poisons, each with different effects.

He hadn’t known what use they might have at the time, but Jiang Xu wasn’t afraid of waste. What he feared was needing something and not having it, thus jeopardizing important matters.

As Jiang Xu cautiously fed the Golden Silkworm Gu a mixture of venom from a Tier Two poisonous snake and several rare, highly toxic herbs, the little creature’s reaction made his heart clench.

The mixture of venom and poisonous herbs was as potent as strong liquor. The moment the Golden Silkworm Gu swallowed it, its tiny body began to sway unsteadily, like a drunkard staggering through a storm. Its eyes grew hazy and unfocused, as if it had been overwhelmed by the fierce toxicity.

Watching the Golden Silkworm Gu’s state, Jiang Xu couldn’t help but feel a surge of worry.

Just as Jiang Xu was considering whether to take emergency measures to save the Golden Silkworm Gu, it did not disappoint him.

After a brief moment of turmoil, its tenacious Life Force shone through. First, its body paused slightly, as if gathering strength. Then, its small form suddenly contracted and trembled violently twice, as if it had been electrocuted.

Suddenly, a soft "PFFT" broke the silence. A solid particle, as dark as obsidian, shot out from the Golden Silkworm Gu’s body and landed precisely in Jiang Xu’s hand.

The surface of this crystal was a glossy black, with a strange light swirling within. It radiated a cold, profound toxic aura.

After successfully expelling the toxic crystal, the Golden Silkworm Gu returned to normal. It lazily stretched out and settled into Jiang Xu’s palm, as if contentedly enjoying the peace after a fierce battle.

Jiang Xu breathed a sigh of relief. He carefully returned the Golden Silkworm Gu to its Spirit Beast Bag, his hand tightly gripping the toxic crystal.

After deciding on the poison’s properties, Jiang Xu fed the Golden Silkworm Gu a dose of Soul-devouring Snake venom to ensure its toxic byproduct would achieve the desired effect.

The most distinct characteristic of this venom was its ability to block all of a victim’s senses. They couldn’t even use their Divine Sense and would completely lose control of their body. It was truly terrifying.

The other poisonous herbs had various effects, like causing a slow death or inducing periodic flare-ups of the poison within the body.

Jiang Xu broke off a tiny piece of the crystal, then left the cave to find a wild rabbit to use as a test subject.

After placing the speck of poison in the rabbit’s mouth, Jiang Xu saw it instantly freeze in place. It showed no reaction at all, no matter what Jiang Xu did.

Next, Jiang Xu took a tiny drop of the Golden Silkworm Gu’s blood and placed it in the rabbit’s mouth.

The rabbit instantly regained its vitality, though it was clearly terrified and trembling uncontrollably.

Jiang Xu released the rabbit and walked toward where Wuji Fairy was located.

When he arrived, Jiang Xu saw that the defensive barrier around Wuji Fairy had disappeared. She and Zong Ziqi were sitting cross-legged on opposite sides of the space.

The moment she saw Jiang Xu, Wuji Fairy’s entire body tensed. It was as if he had left a permanent shadow on her heart; the mere sight of him filled her with fear.

Seeing this, Jiang Xu smiled at Wuji Fairy.

However, he still had the appearance of a faceless man, and his smile seemed exceptionally bizarre. A shiver ran down Wuji Fairy’s spine.

"What... what are you planning to do!"

Wuji Fairy watched Jiang Xu warily.

Jiang Xu’s recent departure had left her feeling extremely uneasy.

Now that he had returned, alarm bells were ringing loudly in her mind.

"Me? I’m planning to let you go, of course," Jiang Xu said nonchalantly.

"Let me go?!" Wuji Fairy was suddenly overjoyed, forgetting everything else. "Are you serious?!"

"Of course," Jiang Xu said with a faint smile, then opened his right hand in front of Wuji Fairy. "As long as you eat this!"

"What?"

Wuji Fairy froze for a moment, her gaze falling upon the toxic crystal in Jiang Xu’s hand.

The crystal gleamed with a black luster. One look was enough to tell it was nothing good. She was so frightened that she stumbled backward, shouting:

"I won’t eat it! I’m not eating that! You’re trying to poison me!"
