"Long Wuxian, would you go in? Three days later, Elder Bai Kuai will come with others to personally open the stone door for you. Hopefully, we won't have to carry out a corpse then!" Bai Kuo mocked with a sarcastic tone.

Ignoring Bai Kuo completely, Long Wuxian strode towards the depths of the tunnel. With a flicker, he disappeared without a trace, only to reappear at the end of the tunnel where a figure stood.

Watching Long Wuxian disappear into the depths, a faint smile crossed Bai Kuo's face.

Afterward, Bai Kuo took down the sign, and after the stone door made a creaking sound, it closed completely.

"Alright, everyone disperse." Bai Kuo waved his hand at the crowd before vanishing into thin air.

Bei Fengxiao didn't say much and just winked at Han Yu, who shot him a disapproving look.

"Do you think Long Wuxian, talented as he may be, can last three days in there?"

"How is that possible? He's just a Sovereign Realm expert; staying there for a day and night is already a far-fetched idea."

"Sigh! Such a rare genius gone just like that, it's such a pity. Let's hope for a miracle!"

"Let's go, offending the Bei family won't end well. Let's come back later to take a look."

People glanced at the closed stone door once more before turning and leaving.

Most of them shared the same thought – that Long Wuxian was surely dead, with no hope of survival, and in three days, he would undoubtedly become an ice sculpture.

Han Yu shook his head helplessly and then, turning around, disappeared into the crowd.

Except for Han Yu, Fei Yu and the others were the last to leave. Their faces were filled with sadness. After all, the conflict between Long Wuxian and Bei Yuxin was caused by them. If Long Wuxian truly died in the realm of extreme cold and darkness, they would carry a heavy sense of guilt.

"Don't worry, that brat won't die so easily. Do you really think he's a stupid pig waiting to die? Or did he go there looking for death himself?" Yun Xiang said nonchalantly.

"Are you saying that Senior Brother is confident in resisting the cold inside?"

After hearing Yun Xiang's explanation, Fei Yu was also excited, feeling a glimmer of hope.

"Well, I don't know what method he'll use to resist the cold inside, but I know this guy won't go looking for death on his own! Since he actively requested to enter the realm of extreme cold and darkness, he definitely has his reasons. You guys don't have to worry at all. Just wait for a good show in three days. Not only will he not die, but he may even advance to the Sovereign Realm when he comes out."

With a wag of her tail, Yun Xiang showed no signs of worry on her face.

After hearing Yun Xiang's words, Fei Yu and the others breathed a sigh of relief. Although they were still deeply worried, it was much better than before.

Yun Xiang's words made sense. Long Wuxian's extraordinary talent and intelligence meant he wasn't a fool who would seek death willingly.

Deep within the cave.

The void was permeated with bone-chilling coldness, so much so that the cold condensed into a tangible form, freezing even the air, making it difficult to move an inch.

The space in the entire valley was not large, seeming to be only the width of a courtyard.

If an ordinary Sovereign Realm cultivator were to enter here, they would likely faint from the cold on the spot.

But Long Wuxian's complexion remained unfazed as he walked through the valley, allowing the cold to wash over his body without any effect.

With the Nine Jade Dragon Formula running, Long Wuxian absorbed the cold directly.

"What an extraordinary place. Elder Bai Kuai's boasting is unfounded. This definitely isn't something North Wind Snow can create," Long Wuxian shook his head and remarked, finding the realm of extreme cold and darkness as fascinating as he expected.

Not in a hurry to cultivate using the cold, Long Wuxian looked around, trying to find the source of the cold.

Even though this was not a sealed space, Long Wuxian thought the limited space shouldn't have such bone-chilling coldness. He had learned before entering that this place was natural and not artificially created. The rumors about North Wind Snow tampering with it might not be entirely false, given the similar aura to Bei Luoyu.

So, what kind of existence could naturally create such a frozen land?

Long Wuxian believed there must be a root cause.

However, despite his efforts and thorough search of every corner of the valley, he couldn't find the source of the cold.

"It's strange. Where is this cold coming from?"

Long Wuxian frowned, finding the environment very peculiar as the cold seemed to appear out of nowhere.

But everything must have a root cause; all strange occurrences in the world had origins. Long Wuxian couldn't find it now, but it didn't mean it wasn't there.

After an hour of fruitless search, Long Wuxian had to shake his head and give up.

"The cold here seems to appear out of nothing. Every time I try to absorb some, new cold immediately replenishes it. Even using Soul Power to detect, I still can't find the source," Long Wuxian mused, attributing his inability to his insufficient cultivation.

He realized he needed to strengthen his cultivation to perceive the surroundings better. Despite failing to find the source of the cold, he decided to focus on utilizing the three days to make significant progress.

With his profound foundation, using the Nine Jade Dragon Formula to absorb the cold here would greatly help his advancement.

This absorption not only enhanced his cultivation but also tempered his soul power, making his foundation stronger.

Without wasting any more time, Long Wuxian decided to take full advantage of the three days to engage in a killing spree in the realm.

Adjusting himself to the best state, Long Wuxian sank into deep cultivation.

As the Nine Jade Dragon Formula operated, Long Wuxian merged the chilling Chi into his body with his palms in meditation.

This extremely pure cold Chi far surpassed what Long Wuxian had encountered before.

As the Nine Jade Dragon Formula and the absorption of the cold accelerated, mist enveloped Long Wuxian, forming terrifying white ice patterns around him.

Such a method of cultivation and intense absorption of the extreme cold would be astonishing to outsiders if witnessed.

Most people would have given their all to resist the cold here, even practitioners of cold element techniques could only gradually absorb the cold and quickly leave to digest.

Thus, Long Wuxian's fanatical absorption and immunity to the cold were rare.

Long Wuxian cultivated the Nine Jade Dragon Formula, capable of integrating all elements into one entity.

By the night, after a day of absorbing the cold, significant changes started to manifest in Long Wuxian. The absorbed cold and chilling essence within him were stirring, stimulating the potency stored within him.

Under this double stimulation, the final Dragon Vein was entirely occupied by the potent Chi.

Long Wuxian's aura grew restless, as all Chi surged towards his spiritual roots.

The crucial moment arrived – the manifestation of the Emperor's Heart, symbolizing the breakthrough to the Emperor Realm. While most cultivators were excited during this phase, Long Wuxian, unsatisfied with the Emperor Realm, remained indifferent as if it were a routine.

Before breakthrough, a cultivator was like a fractured sea, needing seamless fusion to form a vast internal space.

Long Wuxian operated the Nine Jade Dragon Formula, directing the terrifying Chi towards the dormant spiritual roots.

Challenging the spiritual roots required a methodical approach rather than impatience.

After a night of relentless effort, Long Wuxian successfully created a near-complete space within his body.

Subsequently, the consolidation of the Emperor's Heart and continuous expansion of new spaces were next.

Long Wuxian, newly promoted to the Emperor Realm, managed to form enough space to contain a hundred Emperor's Hearts, a rare feat only seen in exceptional cases, known as the Spirit of the Six Realms!
