I established the Eternal Immortal Clan by taming beasts.

The faint, almost imperceptible feeling, as if being watched by an invisible eye, grew clearer and stronger as Lin Che approached the southern part of the ruins, like cold spider silk coiling around his heart, sending chills down his spine.

Lin Che's expression turned serious. He cautiously stopped and refrained from proceeding rashly.

He immediately activated the Absolute Concealment Divine Power to completely erase his own presence.

Sure enough, the moment his figure and aura were completely concealed, the ever-present feeling of being watched suddenly vanished.

"The root of the problem is indeed here!" Lin Che muttered to himself, his sharp gaze fixed on the square building completely shrouded in thick, inky black miasma.

The building is massive in scale, and faint traces of the runes from the formation can still be seen on its exterior.

But the walls, which should have been incredibly sturdy, were now severely corroded by the terrifying toxins, exhibiting an ominous state of decay.

Wisps of black energy seeped out from it, giving it an eerie and ominous feel.

Lin Che held his breath and focused his attention, using the system's detection capabilities to begin investigating the detailed situation of the formation here.

The findings sent a chill down his spine.

The original core function of this formation was to restrain the experimental demonic beasts kept inside the building and to ensure that the highly toxic gas produced by the Earthly Fiend Poison Vein was firmly sealed inside and would not leak out in the slightest.

However, for some unknown reason, the core of this great formation has long been distorted and alienated, and its function has undergone a horrifying reversal.

Instead of containing the poisonous gas, it has become a continuous and highly efficient "poisonous miasma diffuser"!

This distorted array, like a living, malevolent organ, continuously extracts pure toxicity from the Earthly Fiend Poison Vein, transforming it into a deadly miasma that blots out the sky, endlessly polluting everything around it.

The remaining spiritual veins within the sect were completely corroded, and the vegetation underwent terrible mutations due to the erosion of toxins. The originally docile spirit beasts either died or their bloodlines were contaminated, causing them to go berserk.

Ultimately, these deadly poisons, with nowhere to go, slowly seeped outwards through the long-neglected and damaged protective array of the sect. Over the years, they transformed this once blessed land of the sect into the now lifeless Black Tooth Swamp.

Looking at the cold information displayed on the system panel, Lin Che couldn't help but sigh softly, his emotions a mix of complex feelings.

Judging from the level of the spiritual veins and the potential of the region, this area was probably the best place around Chuyang City in the past.

Unfortunately, this originally precious third-tier spiritual vein has long been completely polluted by the Earthly Fiend Poison, and the spiritual energy has become turbid and full of malevolent energy and toxins.

If ordinary beings were to cultivate here, their fate would likely be the same as those blood-tainted, mad-minded monsters outside.

Now that the root of the problem has been identified, Lin Che would not be foolish enough to risk his life.

With a thought, he vanished from his spot and entered the absolutely safe Azure Profound Realm.

Next, he decided to let the Azure Profound Realm Spirit act on its own.

The Azure Profound Realm Spirit possessed the Absolute Concealment Divine Power, allowing it to hide its form and enter the dangerous building to investigate. Lin Che, on the other hand, indirectly observed the internal situation by sharing his senses with the spirit beast.

In this way, even if they encounter unforeseen dangers, the Azure Profound Realm Spirit can activate its teleportation ability to evacuate on its own immediately, without having to worry about protecting Lin Che. This greatly shortens the activation time of the ability and significantly improves safety.

After clearly receiving Lin Che's thoughts, the Azure Profound Realm Spirit nodded its angular, azure head slightly, indicating that it understood.

As Lin Che entered the secret realm, the figure of the Azure Profound Realm Spirit faded and disappeared from the spot, as if it had merged into the air.

In the distance, the heavy door of that lifeless square building was slowly pushed open a crack by an invisible force, but no one was seen entering.

Inside the building, in stark contrast to the other areas of the ruins filled with frenzied monsters, there was a suffocating silence.

It wasn't that there were no living creatures, but rather that they were all unusually "quiet".

Inside the dilapidated laboratory room, filled with a pungent odor, gathered a group of venomous pythons with circular, putrid markings on their bodies.

They were huddled motionless in the pitch-black, viscous pool of venom, heads bowed, silently absorbing its pure toxins.

The scene was much the same in the outer hall and most of the rooms.

Poisonous miasma permeated the area, with pools of deep-colored poison exuding a strong, foul stench scattered throughout.

Even if Lin Che only "saw" it from afar through shared senses, he could clearly feel the terrifying toxicity it contained.

Beside these poisonous pools, a large number of brightly colored and distorted first- and second-order poisonous spiritual plants grow, which thrive in this extreme environment.

Looking across the entire region, perhaps only a monster like the Corrosive Poison Python, which has an extremely strong affinity and tolerance for venom, could survive in such a desolate place.

This is the place where the Thousand Waters Beast Taming Sect transformed the Corrosive Poison Python into a Flood Dragon.

Lin Che acted decisively, manipulating the Azure Profound Realm Spirit to quietly collect some valuable, high-grade poisonous plants from the outer hall into the Azure Profound Secret Realm without disturbing the dormant venomous pythons in the poison pool.

Then they arrived at the entrance leading to the inner hall.

This is the true core site where the "Evil Poison Dragon" transformation experiment was conducted back then.

"Stay vigilant and be prepared to evacuate at any time. If you sense any danger that you cannot handle, leave immediately without hesitation!" Lin Che solemnly reminded him again through their mental connection.

The Azure Profound Realm Spirit's eyes were calm, and it nodded slightly. Ripples appeared in the space around it, indicating that it was ready to unleash its divine power at any time.

They concealed themselves and silently entered the inner hall.

Through the shared vision, Lin Che carefully observed everything here.

The inner hall appeared unusually spacious, with only one enormous pool occupying most of the space as far as the eye could see.

The liquid in the pool was not the pitch-black venom in the outer hall, but a viscous slurry with an eerie deep purple hue. Just by looking at it from a distance, one could sense the terrifying toxicity it contained, far exceeding that of the outer hall.

In the center of this deep purple poison pool, a strangely shaped dark purple vine was growing.

The main stem of the vine is thick and twisted, covered with a layer of intricate patterns resembling dragon scales, shimmering with a dark luster.

This vine has no leaves; all the vitality seems to be gathered at its tip.

There, hanging was a strange fruit shaped like a heart, pulsating slowly as if it were alive!

The fruit's skin continuously oozes a thick, blood-like black venomous liquid, which drips into the poisonous pool below, making a soft "drip-drip" sound that is particularly clear in this deathly silent environment.

The appearance of this thing startled Lin Che, who was in the secret realm!

The records about the Corrosive Poison Python lineage in the Beast Taming inheritance instantly flashed into his mind.

If a second-tier, mid-grade Corrosive Poison Python can successfully transform into a dragon, its bloodline can be upgraded to a third-tier, mid-grade "Evil Poison Dragon".

If the "Poisonous Flood Dragon" has another heaven-defying opportunity and successfully transforms into a dragon, it can evolve into a "Poisonous Flood Dragon" with a fourth-order top-grade bloodline.

However, there is a rather obscure record in the transmission that mentions this.

If the "Vicious Poison Dragon" happens to fall in a place filled with pure poisonous energy, its flesh and blood containing dragon power, its overwhelming ferocity, and the deadly poison accumulated over thousands of years will intermingle and give birth to a top-grade third-tier evil spirit plant - the Myriad Poison Blood Dragon Vine!

Although he hadn't gotten close enough to examine it in detail using the system, Lin Che could roughly determine its nature based solely on the shape and characteristics of the vines before him.

The dragon scale-like patterns on the vine, the heart-shaped fruit, the black poisonous ooze, and the extreme environment in which it lives all closely match the description of the "Ten Thousand Poison Blood Dragon Vine" in the historical records!

Looking upwards, the pulsating "heart" at the top of the vine is very likely the legendary "Ten Thousand Poisons Blood Dragon Fruit"!

This fruit requires continuous nourishment from the pure poisonous and bloody energy within the earth's veins, and takes tens of thousands of years to mature.

For poison-attribute demonic beasts, this item is an unparalleled treasure. After consuming and refining it, there is a great chance that their bloodline will be purified, and they may even undergo a reversion to their ancient ancestors!

If a "poisonous dragon" were to swallow this fruit at this moment, its success rate in transforming into a dragon would soar to an astonishing level!

And this is only its most basic use. It is also the absolute main ingredient for refining the third-grade top-quality spiritual pill "Dragon Transformation Nascent Soul Pill"!

This is an unconventional infant-transforming pill!

It can help a poison cultivator who has reached the Golden Core stage shatter their core and transform into an Infant, thus ascending to the heavens in one step!

Once news of the appearance of such spiritual objects spreads, it is enough to drive Golden Core cultivators mad, and even attract Nascent Soul monsters to fight for them!

Thinking of this, Lin Che's heart began to pound violently, and an impulse arose within him to immediately have the Azure Profound Realm Spirit come forward to pick it.

However, in the next instant, he forcibly suppressed this impulse.

His cautious nature, honed over the years, made him keenly aware that something was amiss.

"Something's not right! It's too quiet here!" Alarm bells rang in his mind.

The experimental base had long been dilapidated, and the isolation array between the inner and outer halls had long since failed.

Compared to the outer hall, this is the true core of the Earthly Fiend Poison Vein, where the poisonous gas should be more concentrated and pure, making it more attractive to the Corrosive Poison Python.

Why are there still a large number of venomous pythons in the outer hall, but in the core inner hall, apart from the strange vine in the pool, there is no trace of any venomous python?

This is extremely unreasonable!

There is only one explanation left.

Beneath this seemingly calm, deep purple pool of poison, there must lie some far more powerful being, one that none of the Corrosive Poison Pythons dare to approach.

Lin Che suppressed the excitement in his heart and his desire for the Ten Thousand Poison Blood Dragon Fruit, and did not act rashly.

He gestured to the Azure Profound Realm Spirit to temporarily shift his attention away from the eerie poisonous pool and turn it toward the seemingly inconspicuous wooden house beside the pool.

That place must have been where the monks who conducted the experiments lived and kept records back then.

After confirming once again that there was no hidden danger outside the wooden house, Lin Che allowed the Azure Profound Realm Spirit to enter the house discreetly.

The interior of the wooden house was quite simple. Apart from some everyday utensils that had long since decayed, the most conspicuous items were a considerable number of broken jade slips scattered around.

Lin Che instructed the Azure Profound Realm Spirit to collect all the jade slips and bring them back to the Azure Profound Secret Realm. Then he began to examine their contents one by one.

His divine sense quickly swept over the jade slip, which contained almost entirely the experimental logs, data, and related research insights of the Water Mirror Immortal.

Detailed experimental records of the young "Poisonous Flood Dragon" with a third-order bloodline were prominently listed.

As Lin Che read the book carefully to the end, his emotions rose and fell with it.

The experiment actually succeeded!

Under the tireless nurturing and encouragement of Master Shuijing, the wicked serpent finally overcame the insurmountable barrier of bloodline and successfully transformed into a dragon!

However, what should have been a joyous occasion turned into a disaster and nightmare for the sect in an instant!

The root cause is that this venomous dragon was not bred by the sect itself, but was a cub that they forcibly abducted from the wild by killing its parents.

This deep-seated hatred had long been buried in the heart of the Fiend Dragon, kept hidden and waiting for the right opportunity.

Just as it successfully transformed into a dragon and reached the peak of its power, the hatred that had been accumulating for countless years finally erupted!

It first tore several of the Thousand Water Beast Taming Sect's experimental personnel to pieces with lightning speed.

Master Shuijing was shocked and furious, and immediately took action to try to subdue this newly emerged "poisonous dragon".

However, after transforming into a dragon, the Fiendish Flood Dragon's strength increased dramatically, far exceeding expectations. Coupled with its desperate and frenzied counterattack, even Master Shuijing found it difficult to suppress it, and the situation became extremely precarious.

Left with no other choice, Master Shuijing reluctantly activated the deadly formation set up around the test site, intending to completely annihilate this out-of-control ferocious beast.

But no one expected that the real terror was only just beginning.

Before its death, the venomous dragon used all of its bloodline essence and boundless resentment as a catalyst to unleash its newly awakened curse-type divine power!

This power, containing its most malevolent curse, instantly corrupted and reversed the core formation of the testing ground.

The great array that was originally used to prevent the spread of toxins has been completely distorted, turning into a source of pollution that continuously draws out the earth's Fiend Poison Veins and spreads deadly miasma outwards!

At the same time, the remnant soul of the Fiend Dragon, filled with endless resentment, transformed into a terrifying curse that covered the entire sect.

All living beings within the scope of the curse, whether spirit beasts or cultivators, will have their minds gradually eroded, becoming extremely prone to rage and losing their reason, ultimately falling into a mad state of mutual attack and self-destruction.

And this is just the beginning.

Even more terrifying is that once a cultivator kills one of the cursed demonic beasts in this place, the vicious curse power of the Fiend Dragon will creep up on them like a bone-deep infection.

After this, cultivators will find it increasingly difficult to calm their minds during meditation and cultivation, and their Dao heart will become increasingly unstable. Even if they break through to a minor realm, they are very likely to encounter the backlash of inner demons, which is extremely dangerous!

These problems soon emerged within the sect. As the sect leader, Master Shuijing made a decisive decision and ordered all disciples to evacuate immediately.

They activated the sect's protective formation, attempting to contain the toxins and curses within and prevent them from spreading further and harming all directions.

He himself chose to stay in this desolate place, trying to find a solution.

Unfortunately, he tried many methods, but all of them ended in failure.

The environment here has deteriorated completely, the spiritual energy of the spiritual veins has begun to dissipate, making cultivation impossible. In the end, this cultivation base could only be abandoned and disappeared into the long river of history.

After reading all the records, Lin Che couldn't help but let out a soft sigh, his heart filled with mixed emotions.

"Humans and spirit beasts cannot truly coexist harmoniously simply through a contract rune!"

Both following the path of beast taming, the tragic experience of Master Shuijing undoubtedly served as a warning to Lin Che.

Spirit beasts are not mindless tools; they possess their own emotions, memories, and will. Mere enslavement and oppression will eventually sow the seeds of hatred and bring about a backlash!

Shaking his head, Lin Che's gaze returned to the eerie, deep purple pool of poison, and the pulsating Blood Dragon Vine in the center of it.

At this point, all his doubts were resolved.

That persistent, elusive sense of being watched originates from the malevolent curse permeating the air, stemming from the remnant soul of the wicked dragon!

He also fully understood why the Zhao family was so "generous" in publicly announcing the ruins and inviting a large number of independent cultivators to come.

The Zhao family must have killed a demonic beast here during their previous exploration, thus discovering the existence of that strange curse.

If they want to delve into the core of the ruins to obtain the true resources and inheritance, they must clear away the countless cursed and corrupted monsters along the way.

But personally taking action means that all family members could be cursed, with endless consequences.

So they came up with this plan to kill someone using someone else's knife.

They used unsuspecting cultivators to "cleanse" these cursed monsters!

Once the rogue cultivators have exhausted all their efforts, even paying a heavy price, to clear away the obstacles and unknowingly bear the curse, the Zhao family can easily reap the fruits of victory at the lowest cost and enter the interior to obtain what they truly desire!

If Lin Che were to rashly attack and kill the demonic beast without knowing these things, he would definitely fall victim to its attack, and no matter what methods he used, they would be useless.

As long as his path is damaged, the Lin family will be no threat, and they will be able to eliminate their opponent without bloodshed.

Having seen through all of the Zhao family's schemes, Lin Che's eyes narrowed slightly, a cold glint in them.

A plan to use their own methods against them and take advantage of the situation to target the Zhao family instantly came to mind.
