Starting as dockworkers, they swept through Chongqing.

He gently placed it on the table.

Inside the vial, a thick, red liquid, resembling burning blood, flowed. Even through the glass, Xilun could sense the immense, heart-pounding life energy contained within it.

"This is a red heart medicine made from the purest red heart tree sap, along with a variety of precious auxiliary ingredients."

Lund's eyes showed a hint of fatigue, clearly indicating that he had put a great deal of effort into refining this thing. "This potion has a remarkable body-tempering effect on the vast majority of extraordinary individuals."

This was something I rushed to finish making just before the competition.

"However, it has one extremely fatal characteristic."

That is because the energy is too vast and violent; the user absolutely cannot refine it in a short time.

Lund pointed to the potion and explained, "Under normal circumstances, a first-tier extraordinary person needs to be in a completely quiet environment and secluded for seven days and seven nights to take this potion."

Over these seven days, one must slowly grind the medicine with all one's might to initially refine it and obtain one-third of its medicinal power.

Then, over the remaining two to three months, like water dripping on a stone, the remaining two-thirds of the medicine's potency will be slowly absorbed.

Xilun frowned and said, "Teacher, do you mean this potion wasn't originally prepared for the competition?"

"That's right." Lund nodded. "My original plan was to have you take it after the competition was completely over, regardless of your ranking, and then let you digest it slowly. This was mainly to prepare you for the 'Snow Mountain Wonderland' that would open in three months."

"After all, while rankings in a competition are important, they are ultimately something that cannot be forced."

But that snow-capped mountain wonderland is one of the few opportunities that all extraordinary people dream of.

If you gain something from it, it can benefit you for a lifetime.

At this point, Lund's tone abruptly changed, and his eyes became intense:

"But what if you really have that absolute talent for adapting to extremely cold and deep water environments!"

Then perhaps you could try a dead-end path that no one has ever taken before—try forcibly refining it!

Lund stood up, placed his hands on the table, and looked at Xiren with an imposing gaze, his voice low and deep:

"Deep in the back mountain of this Daewoo Dojo, there is a special training ground."

If you make this request to the gym owner, Fowles, under the guise of preparing for the finals, as a special request from the contestant, he will likely grant it out of consideration for the player.

"What you are about to enter is one of the seven major training grounds of the dojo—the Frozen Pool and Icefall!"

"The area is covered in ice and snow all year round. The waterfalls falling from hundreds of meters in the air are icy cold and have extremely high water pressure, making the environment very difficult to adapt to."

Even second-tier extraordinary individuals can only barely reach the edge.

Only a third-tier expert can fully adapt to that extreme cold.

"And you! If your internal organs can really barely adapt to that cold."

Then you can use the immense natural water pressure and extreme cold of the training ground to externally compress your body, stimulating your muscles and meridians, thereby forcibly draining and digesting the explosive power of this red-hearted potion within three days!

Upon hearing Lund's words, Xilun showed no fear whatsoever; instead, a raging fire ignited in his eyes.

He abruptly stood up, grabbed the vial of red medicine from the table, clenched it tightly in his hand, and spoke with a resolute and unwavering tone:

"In that case, let's set off immediately, teacher."

……

On the top floor of the Daewoo Dojo, in the office of Dojo Master Fowles.

When Lund brought Xiren to apply for pre-match training at "Frozen Pool and Icefall," Fowles, sitting behind the mahogany desk, slightly raised his eyelids.

The unfathomable fourth-tier demon hunter's gaze lingered on Xilun's slightly thin body for a few seconds, as if trying to see through what gave this young man the confidence to challenge such a perilous place.

"The icy pool and waterfall are not exactly scenic spots, Lund. Are you sure your students can withstand that kind of bone-chilling cold?"

Don't blame me for not warning you, even a first-tier extreme realm extraordinary individual's blood will completely congeal if soaked in it for ten minutes.

Fowles' voice was calm, yet carried an undeniable air of authority.

Lund bowed respectfully and said in a deep voice:

"Master, Xilun's physique is somewhat special."

Moreover, with the final three days away, we have no way out but to take a risky approach.

Fowles paused for a moment, then picked up the quill pen on the table, signed his name on the application in a flamboyant style, and stamped it with the seal bearing the emblem of the church.

He handed the letter to Lund and said calmly, "Since you insist on this, then I will grant his wish. Life and death are predestined. Go."

After thanking them, the two immediately left the office with the letter.

Led by the special attendant of the Daewoo Dojo, Xiren and Lund passed through the dojo's layers of steel buildings and arrived at the back mountain of the dojo.

This place is sparsely populated, and the further you go in, the sparser the surrounding vegetation becomes, and the temperature in the air drops at an alarming rate.

Along the way, they encountered several groups of heavily armed and imposing guards at checkpoints.

The attendant leading the way presented the letter from the owner of the Fowles Pavilion. After the guards carefully checked it and found it to be correct, they looked at Xilun with a mixture of surprise and confusion before letting them pass.

The two continued walking deeper into the canyon.

Before even seeing the waterfall, Siren could already hear a terrifying roar, like ten thousand horses galloping.

Turning around a huge, cold rock corner, the scene before him instantly shocked Xiren.

A huge waterfall, tens of meters wide, crashed down from a steep cliff hundreds of meters high.

As the massive torrent of water fell, it created a cloud of white mist, resembling a silver, angry dragon descending from the sky.

The surrounding temperature had suddenly dropped below zero, and the rocks were covered with thick icicles.

Even standing a hundred meters away from the waterfall, the icy air from the water hitting your face can make your skin feel like it's being pricked with needles.

It wasn't until they officially entered the core area of ​​the "Frozen Pool and Icefall" that the air inside became incredibly cold, chilling to the bone.

Lund walked to the edge of the pool, and his breath instantly condensed into white ice crystals that fell down.

He turned to look at Xilun, and asked with a solemn expression:

"How's it going? It's already this cold before we even get in the water, can you handle it?"

Xilun was only wearing a thin coat, and he felt extremely cold. The chill seemed to have eyes, relentlessly trying to penetrate his pores.

However, his "adaptive viscera" talent had been automatically triggered, and his heart was beating at an unprecedentedly steady frequency, forcibly delivering warm blood to his limbs and bones to resist the cold from the outside world.

Xilun took a deep breath and nodded slightly, saying, "Fortunately, it's completely within the acceptable range."

He took a few steps closer and carefully observed the body of water in front of him.

The waterfall, hundreds of meters high, crashed down with a thunderous roar, its sound echoing across the water's surface. The unparalleled power of nature made one feel insignificant.

Below the cascading waterfall lies a deep pool, tens of meters in diameter.

The pool of water was an extremely eerie azure blue, bottomless and still, without even a ripple on its surface, as if completely unaffected by the raging waterfall in the distance.

A thick layer of white mist floats on the surface of the cold pool, partially obscuring the scene in the water and exuding a deathly silence.

Lund stood on the shore, pointing to the deep blue water, and said:

"The surface of the water looks okay, but once you go deep underwater, you'll feel what true extreme cold is."

It's a temperature that can freeze a person's soul.

However, since you're feeling alright now, you should be able to manage.

As he spoke, Lund solemnly handed over the vial containing "red heart tree sap," and instructed:

"In a moment, hold the medicine in your mouth and don't swallow it."

Once you dive into the water, and your body is completely enveloped by the extreme cold of the pool, and your muscles contract violently from the cold, then you should consume it.

Remember, use water pressure and cold air to squeeze out as much of the medicinal power as possible!

Xilun took the medicine and nodded slightly.

Without the slightest hesitation, he went straight to the rocks at the edge of the cold pool, took off his tattered coat and trousers, leaving only a pair of shorts.

His strong upper body was wrapped in several bandages that were seeping blood.

He uncorked the potion, poured the red liquid that looked like it was burning with flames into his mouth, closed his lips tightly, and held it under his tongue.

Then, he leaped into the deep blue, icy pool.

"Thump!"

The moment he fell into the water, only one word remained in Xilun's mind: cold!

The cold was absolutely bone-chilling, as if countless icicles had instantly pierced every pore of his body, trying to freeze his blood into ice shards in an instant.

Xilun dared not slack off in the slightest and immediately began frantically circulating the "Great Sea Whale Guiding Technique" within his body.

Deep blue water-attribute energy surged through his meridians, desperately resisting the invading cold from the outside world.

At the same time, his internal organs began to slowly regulate their functions, and his heartbeat became steady and powerful, forcibly maintaining the core temperature in his body to prevent his internal organs from failing.

Xilun tried moving his limbs underwater and was surprised to find that the water in the cold pool felt very viscous, like liquid mercury, and the water pressure was extremely high.

The dense chill seemed to have a life of its own, frantically drilling into his pores.

Just as his body began to tremble uncontrollably from the extreme cold, Xilun swallowed the red heart potion he had been holding in his mouth!

boom!

The moment the medicine entered his stomach, Xilun felt as if he had swallowed a red-hot piece of charcoal!

An extremely hot and violent energy exploded within his body in an instant.

Outside is an extreme cold that can freeze the soul, and inside is a fiery heat that seems to burn the internal organs.

Hot and cold, two extreme temperatures constantly alternate and collide within Xilun's body!

Under the relentless pressure of the cold air and water, the stubborn medicinal power that originally required seven days to be initially refined began to be forcibly extracted little by little and integrated into Xilun's limbs and bones.

"It really works!" Xilun endured the inhuman torment of being torn between ice and fire, secretly delighted.

While this digestion speed cannot compare to direct absorption, it is already incredibly fast for someone refining such a top-grade universal cultivation potion for the first time, under the dual stimulation.

He glanced down at the bottomless azure pool below, thinking to himself that perhaps the deeper he went, the greater the water pressure and the colder the air would be, resulting in a more intense pressure on his body.

So, head down, he pushed off with his legs and began trying to dive deeper.

Ten meters, twenty meters...

As he descended deeper, the temperature became even colder and more terrifying, and the viscous water pressure felt as if it would crush his bones.

Although he possesses the breathing technique of the Great Ocean Whale, which allows him to hold his breath underwater for extended periods, and his adaptive internal organs enable him to barely maintain his core body temperature in cold environments, the limits of his physical endurance are ultimately limited.

When they reached a depth of 30 meters underwater, Xilun felt as if his skin was about to crack from the cold.

He finally gave up on continuing to dive, figuring that the current depth of about thirty meters underwater was roughly the limit of his current physical ability to dive.

So, Xilun floated cross-legged in the water and began to enter a meditative state.

He made his mind extremely clear and completely controlled every muscle in his body.

Inside his body, he methodically circulated his breathing, exhaling and inhaling to guide the medicinal power to repair the tiny muscle fibers torn by the water pressure.

This alternating torment of ice and fire lasted for a full two hours.

Xilun felt the terrifying water pressure around him slowly draining his strength, leaving him almost completely exhausted.

Even with his frantic breathing techniques, he could no longer maintain a depth of thirty meters underwater.

"Splash!"

Finally, Xilun suddenly surfaced from underwater, his head breaking the surface as he greedily inhaled the icy air.

Lund, who had been standing on the shore with his nerves on edge, finally breathed a long sigh of relief when he saw Xilun emerge.

In those two hours, if he hadn't been a third-tier expert who could faintly sense the life force of Xilun underwater, which was like a candle flickering in the wind yet still full of vitality, he would have jumped into the water to rescue him.

Xilun swept his gaze across the water's surface. He desperately needed to find a place to practice breathing exercises to replenish his depleted energy so he could continue refining the immense medicinal power within his body.

His gaze swept across the area and he saw a huge black stone platform protruding from the water directly beneath the massive icefall.

Xilun swam over, climbed onto the stone platform, and sat down cross-legged on it.

This stone platform faces the core area of ​​the icefall that cascades down hundreds of meters.

As soon as Xilun settled down, the enormous torrent of water, like a cascading Milky Way, crashed down on his head and shoulders.

"Boom!"

Xilun originally thought that his physical body was already incomparably strong, and that even Li An's sharp battle blade could only barely penetrate a few inches.

However, at this moment, being violently impacted by the icy water carrying enormous gravitational potential energy, he felt as if his entire skeleton was about to fall apart!

His body was loosened and stiff from the impact, and the pervasive chill penetrated deep into his bones through the pores opened by the water, causing him to let out a painful groan.

But Siren did not back down.

He gritted his teeth, facing the impact of the waterfall, constantly inhaling and exhaling, refining his strength.

At the same time, a flash of inspiration struck him, and he began to actively activate his talent for "charge accumulation" on his body surface.

Through the friction of the water flow, he controlled his body to collect tiny free charges in the air and water.

These silvery-blue charges formed a network of lightning that adhered to his body surface, frantically tempering his flesh, which had been numb from being pounded by the water.

Under the combined effects of water pressure, immersion in a cold pool, the fiery power of the medicine, and the paralysis of electrical charges, Xilun's breathing exercises gradually got on track.

He felt that many weak and vulnerable areas in his body that he couldn't previously overcome were being filled and repaired little by little by the medicinal power under this all-round extreme pressure, slowly moving towards perfection.
