Mortal: I became invincible after becoming sworn brothers with Han Li.

Chapter 169 Ten Years to Form the Core

After returning to his cave, Li Yunfan went straight to the cultivation room.

After releasing the ice, he sat cross-legged on the futon again and began to temper the blue-white spirit fire.

This blue and white flame can absorb cold air to strengthen itself, but it is cold on the outside and hot on the inside, which is extremely strange.

"I wonder what it will look like after this spiritual fire is fully tempered—" Li Yunfan thought to himself.

He then placed his hands in a mudra over his dantian, slowly closed his eyes, and began to circulate the Nine Revolutions Burning Heaven Technique, using its secret method to temper the spiritual fire.

This time, it took him a full seven months to completely refine it.

After being tempered by him, the color of the spirit fire changed dramatically.

The flames, which were originally blue and white, are now only white, resembling a ball of bone fire, which looks quite eerie.

Although Li Yunfan didn't know why this change had occurred, he guessed it was related to Bing'er's fellow cultivators.

Because during those seven months, he helped Bing'er control the bursts of cold energy within her body twice.

Each time the cold air emitted by Bing'er entered his body, a portion of it was absorbed by the blue and white spirit fire.

Judging from its appearance alone, it is hard to imagine that this white flame, which exudes a chill, actually contains an extremely hot temperature.

Therefore, Li Yunfan named this fire "Netherworld Cold Mystic Fire"!

However, he did not stop cultivating after that. Instead, he spent several more years pushing his cultivation level to the peak of Foundation Establishment and entering the Pseudo-Core Realm!

The reason why he cultivated so quickly was largely due to his fellow cultivation with Bing'er.

After these three fellow cultivation sessions, Li Yunfan could clearly feel that his speed of absorbing spiritual energy was two or three points faster than before!

His Fire Spirit Body was already comparable to cultivators with Heavenly Spirit Roots in terms of cultivation speed, and now it has improved even further, leaving those with Heavenly Spirit Roots far behind.

His body also experienced some conditions that he himself couldn't explain due to the combination of cold and heat.

His body was originally cultivating the Nine Revolutions Burning Heaven Technique, and after three temperings with spiritual fire, it was gradually transforming into an innate fire spirit.

But now, after the interaction of cold and heat, the red spiritual threads in his body's muscles and bones are slowly fading away.

Instead, specks of purplish-gold light began to emanate from the bones.

Li Yunfan didn't know whether this change was good or bad.

On this day, Li Yunfan, who was meditating in meditation, slowly opened his eyes.

He glanced down at Bing'er, who was lying on his lap, and a strange look flashed in his eyes.

Now, some wonderful changes have also occurred in Bing'er.

First of all, her body, which was originally ice-cold, now feels faintly warm to the touch.

Secondly, her cultivation level has already emitted spiritual energy fluctuations comparable to the sixth level of Qi Refining!

You should know that when Bing'er was underground, she never cultivated because of the special nature of her Ice Marrow Cold Spirit Body.

And this only took five years!

The speed at which his cultivation improved left even Li Yunfan in awe.

If she continues cultivating like this, Bing'er might actually advance to the Nascent Soul stage within three hundred years. Li Yunfan gently patted Bing'er awake, told her he was going out for a while, and then put her into his spirit beast bag.

After getting up and leaving the cave, Li Yunfan went directly to the main hall on the main peak and found the sect leader, Wu Qingming.

Looking at Li Yunfan in front of him, Wu Qingming's face was full of shock.

The other party had only been in the Luoyun Sect for a few years, yet he had directly jumped from the late Foundation Establishment stage to the Pseudo-Core stage!

When Li Yunfan first came to the sect, he saw him clearly; he had only recently entered the late stage of cultivation.

Such a terrifying cultivation speed is something that even cultivators with Heavenly Spiritual Roots can only look up to.

Li Yunfan didn't offer any further explanation, but instead directly inquired about the location of the market town near Yunmeng Mountain.

"Junior brother, do you perhaps want to buy Heavenly Fire Liquid and Snow Spirit Water for Core Formation?" Wu Qingming asked directly after hearing Li Yunfan's words.

"That's right, these are the two kinds of spiritual herbs!" Li Yunfan nodded and said.

Seeing this, Wu Qingming chuckled and said, "The sect has some of these two kinds of spiritual herbs, so Junior Brother doesn't need to go to the market to buy them!"

Upon hearing this, Li Yunfan couldn't help but show a hint of surprise. Although these two spiritual herbs were not as rare as thousand-year-old spiritual herbs, they were still very precious. He never expected that Luoyun Sect would have them.

"These two spiritual herbs are essential for breaking through to the Core Formation stage, and the sect naturally keeps some on hand. Junior brother, you can take my token and go directly to the Pill Pavilion on Tianquan Peak to purchase them!"

Wu Qingming smiled and explained, then took out his sect leader token and handed it over.

Li Yunfan accepted the token with a surge of joy, and quickly cupped his hands in thanks.

Then, under Wu Qingming's watchful gaze, he turned and left the main hall.

"I never expected to find such a cultivation genius for our sect this time. I just wonder if he can successfully form his core—"

Wu Qingming said something in a low voice, and then let out a long sigh.

After speeding along the Cloud Piercing Boat to the "Dan Pavilion" on Tianquan Peak, the disciple in charge quickly brought out two jade boxes after I showed him the sect leader's token.

I opened it and took a quick look; inside were two different liquids.

One was transparent and clear, emanating a chilling aura, while the other was scarlet and fiery, radiating a scorching heat.

Upon seeing these two kinds of spiritual liquids, Li Yunfan could not hide his joy.

After spending a large sum of spirit stones to store the two boxes in his storage bag, he bought some pills to restore his spiritual power before leaving Tianquan Peak and returning to his cave.

As soon as he entered the cultivation room, he released Bing'er before sitting down cross-legged.

"Now that we have the spiritual liquid necessary for Core Formation, we can begin cultivating the third level of the Great Evolution Technique—"

After thinking it over, Li Yunfan took a deep breath, slowly closed his eyes, and began to circulate the Great Evolution Technique.

After undergoing three fire temperings, the difficulty of breaking through the bottleneck has been greatly reduced.

Adding the third level of the Great Evolution Technique can increase the chances of forming a Golden Core.

It can be said that the difficulty of his Core Formation is much lower than that of other Foundation Establishment cultivators.

But whether he could succeed on the first try was something Li Yunfan himself wasn't very confident about.

And so, Li Yunfan once again entered into seclusion for arduous cultivation!

One or two days —

January and February —

One year, two years —

Time just slowly passed by.

Li Yunfan, who was inside the cave, would only open his eyes to help Bing'er dispel the cold energy when she unleashed it; otherwise, he would cultivate with his eyes closed.

Before we knew it, ten years had quietly passed.

On this day, the clear blue sky above Huoyun Peak, which was originally cloudless, suddenly changed color!

A large, dark cloud gradually gathered above Fire Cloud Peak, with silver lightning flashing wildly and deafening thunderclaps resounding continuously.

At the same time, the spiritual energy of heaven and earth from all directions began to rotate and roar, forming a huge vortex with a diameter of several miles, centered on Fire Cloud Peak!

The spiritual energy within a radius of dozens of miles was completely absorbed by the vortex.

This caused the many disciples who were cultivating on Fire Cloud Peak to fly out in shock and astonishment.

Upon seeing the astonishing celestial phenomenon in the sky, everyone's expression changed drastically.

Such a scene only occurs when breaking through to the Golden Core stage; someone broke through to the Core Formation stage on Fire Cloud Peak!

The disciples stared blankly at this scene, their faces displaying a variety of expressions, a truly rich tapestry of emotions!

Just then, Duan Xianyang, the peak master of Huoyun Peak, and Li Xuan, the deputy peak master, also flew out from the main hall at the summit.

Upon seeing this magnificent sight, the two exchanged a glance, both seeing surprise and delight in each other's eyes.

"Senior brother, our Fire Cloud Peak will soon have a new Core Formation cultivator!" Vice Peak Master Li Xuan said with delight.

Duan Xianyang nodded with satisfaction, then looked at the center of the spiritual energy vortex and asked with some curiosity, "I wonder which disciple is condensing their golden core."

"None of our disciples have reached the Pseudo-Core stage. Could it be one of our other disciples? Or perhaps—"

Before Vice Peak Master Li Xuan could finish speaking, he was interrupted by a loud bang that suddenly appeared in the sky.

Suddenly, a thick red lightning bolt flashed across the dark, heavy clouds, followed by a thunderclap.

Within that vast expanse of dark clouds, streaks of red spiritual light gradually began to emanate.

Upon seeing this, the two couldn't help but show astonishment, as they had never heard of such a change occurring during the Core Formation celestial phenomenon.

"Senior brother, this—" Deputy Peak Master Li Xuan stared at the sky in astonishment, not knowing what to say for a moment.

Peak Master Duan Xianyang was equally puzzled and began to doubt whether this was indeed a phenomenon related to Core Formation.

However, the strange phenomenon in the sky ignored all of this; the originally dark and heavy clouds had turned into a fiery red color.

As the third bolt of red lightning struck down, a massive hole, hundreds of feet in size, slowly appeared in the center of the red cloud, as if it had been pierced by something.

Immediately afterwards, wisps of fire-attribute spiritual energy rose from the vortex of spiritual energy that swirled around Fire Cloud Peak, converging towards the center of the red cloud.

And within it, it coalesced into a huge red spirit sphere!

Just as the spirit sphere was completed, a red beam of light suddenly shot out from a certain location in Fire Cloud Peak, heading straight for the spirit sphere!

"Bang!"

With a muffled thud, a powerful surge of spiritual energy instantly spread out from the spirit orb, sweeping across the surrounding area!

Those low-level disciples in the Qi Refining stage all cast protective spiritual shields to block the impact of this spiritual power.

At this moment, the spirit sphere that was blasted apart by the red light pillar also transformed into countless red spirit threads that surged toward Fire Cloud Peak!

As the red spiritual energy disappeared, the vortex of spiritual energy surrounding Fire Cloud Peak also gradually dissipated.

The red fiery cloud in the sky also vanished without a trace, like a bubble.

The next moment, an extremely powerful divine sense suddenly emanated from Fire Cloud Peak, sweeping over everyone nearby.

Duan Xianyang and Li Xuan's expressions changed, and they flew towards a certain location on Fire Cloud Peak.
