Long Wuxian knew this very well, so the process of breakthrough was not too intense.

After a whole night passed, a nearly complete space was opened up inside Long Wuxian's body.

Once the spatial area of the sea was opened up, the next step was to condense the Emperor's Heart.

When a cultivator's Emperor's Heart first condensed, it was just the size of a thumb, similar to a common pill. Therefore, when ordinary cultivators broke through to the Emperor Realm, the spatial area they could open up was slightly larger than the Emperor Realm, just enough to accommodate the Emperor's Heart.

After forming the Emperor's Heart, the next step was to constantly open up new spaces.

For someone like Long Wuxian who had just reached the Emperor Realm and already opened up a space large enough to hold a hundred Emperor's Hearts, it was truly rare, deserving the title of the Spirit of the Six Realms!

In general, for a master in the Emperor Realm to open up such a large space was already quite impressive.

Once the spiritual root space was opened up, besides storing their own Chi, it could also serve as a storage space for storing precious treasures, much more convenient than relying on storage bags.

However, for ordinary Emperor Realm cultivators, because their internal space was too small, they still had to rely on storage bags.

A space like the one Long Wuxian had opened up was already able to store a small amount of items.

"Although it's not as perfect as I imagined, it's still quite good."

The Nine Jade Dragon Formula continued to operate, reaching the limit after opening up a pool-sized space within the spiritual root. The next step was to condense the Emperor's Heart.

The Emperor's Heart was the most crucial step in entering the Emperor Realm. Only after successfully condensing the Emperor's Heart and reaching the Emperor Realm could one be considered a true cultivator.

This step was not easy. Besides requiring full concentration, it also needed a large amount of spirit stones as reserves. Once the creation of the Emperor's Heart failed, the difficulty of condensing it again would increase several times, not to mention the shadow left in the heart from the first failed attempt.

Fortunately, with the assistance of the soul of a Holy Emperor expert, Long Wuxian found the condensation process quite easy.

As for advancing to the next realm, the Chi he stored now was enough for him to break through to the mid or late stage of the Emperor Realm.

"After this advancement to the Emperor Realm, I'll need to find a way to get more spiritual stones. I'll need to stock up on them, or else it will be troublesome if I can't find them when I need to advance," Long Wuxian thought as he looked at the few remaining spirit stones in his bag.

Buzz...

Suddenly, the Chi in his body started to vibrate, and a large amount of Chi began to converge.

Before long, the embryonic form of an Emperor's Heart appeared in the center of the vortex.

Soon, Long Wuxian's Emperor's Heart was completely condensed. The whole process was very smooth, with no hint of stagnation.

The successfully condensed Emperor's Heart was about the size of a thumb, several times larger than the average Emperor's Heart in terms of volume.

What's more, Long Wuxian's Emperor's Heart was composed of multiple colors and patterns, emitting a unique Chi fluctuation.

This situation left Long Wuxian very satisfied. It seemed like this advancement would bring great benefits!

Moreover, the strength of the Emperor's Heart not only depended on its size but also on its quality. Long Wuxian's Emperor's Heart, fused with various elements, was obviously much stronger than an average Emperor's Heart.

Swoosh...

Long Wuxian retracted the Chi leaking from his body, and the icy patterns on his body disappeared. After advancing to the Emperor Realm, his aura changed drastically.

Long Wuxian gently extended his finger, and flames were seen dancing on it, combining fire with lightning to produce purple flames.

"Ha ha ha, I've actually reached the later stage of the Emperor Realm, not bad..." Long Wuxian grinned as he extinguished the flames by clenching his fist.

With half a day left until the end of the process, his profound foundation and stable cultivation level in the post-Wu Dan Realm gave him confidence. However, since he was already here, why not make good use of the environment?

With this thought, Long Wuxian adjusted his state to its best, activating the Nine Jade Dragon Formula once again. He absorbed a large amount of cold air and began a frenzied impact towards the bottleneck of the late Emperor Realm.

For Zhang Tianze, entering this extremely cold place was truly a great opportunity, bringing him immense benefits.

Meanwhile, inside the inner gate.

"It's been two days already. I wonder how Long Wuxian is doing now. I'm guessing he's probably dead."

"Yeah, who can survive in that ghostly place for three days? It's a pity. I doubt Yu Tianlong's half-year agreement will happen now."

"I still think Long Wuxian might create a miracle. He doesn't seem like a fool. If he dared to enter that place, he must have some reliance."

The outer gate was abuzz with discussions during these three days, destined to not be calm.

In the inner gate, North Wind Smile provided Bei Luoyu with the best healing pills. Bei Luoyu's injuries had somewhat recovered, but she was still very uncomfortable.

"Brother, I wish I could skin Long Wuxian alive!" Bei Luoyu gritted her teeth. Although her bottom no longer hurt, she was still having trouble walking, clearly limping.

"Don't worry, Long Wuxian was thrown into the extremely cold place. It has been two days already. If I'm not mistaken, he must have met his end by now," North Wind Smile replied nonchalantly.

"Brother! Do you think that kid will survive there?" Bei Luoyu asked anxiously, her eyes blinking rapidly, her furrowed brows revealing her worry.

"It's impossible. Even a master at the Holy Emperor Realm wouldn't be able to survive three days in there. Long Wuxian, no matter how extraordinary, wouldn't be able to withstand the cold inside. Just wait to watch the show then," North Wind Smile said confidently. As a named elder of the sect, his words held great authority.

From top to bottom, including the Elder's Hall of the inner gate, everyone knew about Long Wuxian entering the extremely cold place. Many believed it was a shame and had accepted that Long Wuxian was as good as dead, unable to walk out of that valley alive.

The past two days had likely been his end!

Of course...

If the outside world knew that Long Wuxian not only survived in the valley but also successfully advanced to the later stage of the Emperor Realm and was now among the outer disciples working diligently to break through to the later stage, it would shock many to the core.

If Elder Bai Kui found out, he would probably be dumbfounded and heartbroken.

In the valley, Long Wuxian's body once again displayed a blue transparent pattern, his aura continuously rising while merging with the icy air. To him, this was a perfect cultivation environment, ensuring a significant improvement in his cultivation.

Moreover, the icy air here could not only help Long Wuxian advance his cultivation but also refine his physical body, a rare opportunity.

Many practitioners who cultivated cold attribute techniques wished for such icy air to temper their bodies, gaining an advantage in battle.

Inside Long Wuxian's spiritual roots, the Emperor's Heart emitted multiple aura types and rotated like a colorful light sphere.

As Long Wuxian continued to absorb the cold air, the potency of his Chi increased, and the spatial area of his spiritual roots expanded gradually.

Long Wuxian thought to himself that the back mountain of the One Qi Sect was definitely not as simple as it seemed, as he sensed a formidable presence guarding it. Nevertheless, Long Wuxian acknowledged his limited strength and knew that the monster inside might already be at the later stage of the Holy Emperor Realm. Therefore, he decided to avoid approaching it at all costs.

However, wouldn't it hurt to just probe the surroundings a bit?

The greatest strength of an Illusionist was their sensing ability. Since this was a monster at the Holy Emperor Realm, he had to be extremely cautious and prepared.

"Phew... Phew... Phew..."

Long Wuxian breathed evenly, afraid to accidentally alert the monster.

"No wonder people who closed themselves off before found it hard to survive. The main reason was this fellow's presence!" The reason Long Wuxian could perceive the horror of this creature was mainly due to the true power of the Nine Jade Dragon Formula he cultivated.

"If it weren't for the protection of the Nine Jade Dragon Formula, would it have come after me for my life?" Long Wuxian sensed the temperature fluctuations in the area, corresponding to the creature's mood changes.

The final day arrived.

Crack!

The ice patterns, originally as strong as a fortress, suddenly made cracking sounds. Cracks began to appear and spread, eventually exploding into pieces of ice scattering around.

Long Wuxian's figure reappeared, a handsome young man with jet-black hair, who sat cross-legged. As he opened his eyes, two strains of Chi that had been suppressed for a long time emanated from his eyes, creating ripples in the air.

His aura had undoubtedly increased significantly compared to before. Terrifying Chi floated around him, indicating that he had now reached the later stage of the Emperor Realm.

This profound foundation was incredibly strong - the fearsome aspect of cultivating the Nine Jade Dragon Formula was truly revealed.

"This three-day trip to the back mountain has been quite rewarding..." Long Wuxian smiled and slowly stood up from the ground, his gaze fixed in the direction of the entrance.

Three days had passed, and he was eager to see how Bai Kui would react when he opened the stone door and found Long Wuxian alive and well.

At this moment, before the stone door at the entrance of the valley, a crowd had already gathered, creating a bustling scene.

At this time, people should generally be cultivating at the Primordial Qi Square, but now, all the outer disciples have gathered at the back mountain, and even some inner disciples have come, wanting to watch the commotion.

"Hey, do you think Long Wuxian can still be alive?"
