72: Lin Feng's Dan

After sending Xiao Cuier away, Lin Feng turned and returned to his Immortal Cave.

His Divine Sense moved slightly, sweeping over the next door.

Han Li's Immortal Cave was tightly sealed by layers of Restrictions, but it couldn't block Lin Feng's Divine Sense.

After entering, he sensed the Spiritual Qi fluctuations on Han Li's body, indicating that he was preparing to Breakthrough to Foundation Establishment.

"Old Devil Han is finally going to Foundation Establishment," Lin Feng's lips curved into a smile.

Then he, himself, should also go and form a Core.

Entering the Immortal Cave, Han Yunzhi was petting her two small wolves.

Seeing Lin Feng enter, she quickly stood up and bowed, "Young Master."

"Mm," Lin Feng responded, walking to her and reaching out to pinch her tender cheek, "How has your Cultivation progressed recently?"

Han Yunzhi's small face flushed slightly, and her voice was as faint as a mosquito's buzz: "Yunzhi has reached Qi Refining Perfection after taking the Medicinal Pills Young Master gave her, and she can prepare for Foundation Establishment at any time, but Yunzhi is a bit scared to Breakthrough alone."

"Not bad," Lin Feng nodded with satisfaction, "In a few days, I will be your Protector."

He teased Han Yunzhi for a moment, and seeing the girl's cheeks flushed with red, her eyes shy yet with a hint of dependence, he felt amused.

"I will be going into seclusion to Cultivate for a period of time," Lin Feng instructed.

"Yes, Young Master!" Han Yunzhi quickly assented, a hint of shock flashing in her eyes, "Young Master is finally going into seclusion to Cultivate!"

Lin Feng was a bit embarrassed; he had an endless supply of System Medicinal Pills with no resistance, which also meant he had never Cultivated in front of Han Yunzhi.

With a thought, he disappeared from his spot and entered the System Space.

This exclusive space, with his increase in Cultivation and the forging of bonds, had expanded considerably, and the Spiritual Qi was becoming increasingly dense, truly a good place for seclusion and Breakthroughs.

Lin Feng sat cross-legged, his expression calm.

He waved his hand, and dozens of jade bottles immediately appeared before him.

Dustfall Pills, Tranquil Heart Pills, all precious items that aid in Core Formation.

Lin Feng, however, grabbed two handfuls of Medicinal Pills as if they were candy beans and stuffed them into his mouth, swallowing them whole.

The Medicinal Pills melted upon entry, transforming into a vast and pure medicinal power that flowed through his limbs and bones.

The Cultivation Bottleneck of Foundation Establishment Perfection instantly began to waver under the impact of this immense medicinal power.

Lin Feng closed his eyes slightly, his mind sinking into his Dantian.

Within his Qi Sea, the liquid True Essence surged and churned, condensing and gathering at a visible speed.

His Foundation was far more solid than that of most Cultivators, including Han Li.

The groundwork laid by his perfect Foundation Establishment, coupled with the unique Five Elements Spiritual Root bestowed by the System, allowed him to assault Core Formation with almost no obstacles.

No Heart Demon disturbances, no Bottleneck stagnation.

Everything came naturally.

"Boom!"

A roar that seemed to come from the depths of his Soul.

The True Essence within his body completely transformed from liquid to solid, and a Dragon-eye-sized Golden Core, emitting a faint green glow, quietly floated in the center of his Dantian.

It was done!

However, at the very moment the Golden Core formed, the entire System Space experienced a sudden change!

The originally clear sky was instantly enveloped by endless dark clouds, black as ink, churning ceaselessly.

The Spiritual Qi within the space raged wildly, as if the end of the world had arrived.

"Crack!"

A purple Lightning Tribulation, as thick as a water bucket, tore through the dark sky, carrying an aura of destruction, and struck directly at the newly formed green Golden Core—no, at Lin Feng himself!

"Core Formation Lightning Tribulation?" Lin Feng was not surprised but rather delighted, suddenly opening his eyes, a sharp light bursting forth, "Good timing!"

Not only did he not dodge, but he let out a long cry, his figure soaring into the sky, actively meeting the violent Lightning Dragon!

"My Rahu Demonic Body has been stuck at the first layer's Bottleneck for a long time, and I was just worried about lacking external force to help me Breakthrough!

Today, I shall use the power of your Lightning Tribulation to help my Body Refining Breakthrough!"

Before his words finished, mysterious black demonic patterns rapidly spread across his body.

A pure and domineering Devilish Qi burst forth from within him, forming a solid black Qi vortex around his body.

"Boom!"

The first Lightning Tribulation struck Lin Feng's Physical Body with full force.

Terrifying lightning power exploded on his body, with electric snakes dancing wildly and crackling loudly.

Lin Feng felt a jolt of numbness throughout his body, followed by a tearing pain.

But instead of retreating, he Advanced, fully activating the Rahu Demonic Body, frantically absorbing the pure lightning power to temper his Physical Body.

Demonic patterns flickered, and Devilish Qi surged, completely devouring and transforming the scattered lightning power.

"Again!" Lin Feng roared to the sky, his Battle Intent soaring.

"Crack! Crack! Crack!"

The tribulation clouds in the sky seemed to be enraged, as thicker and more violent lightning bolts struck down one after another.

Purple, blue, crimson... various colors of lightning intertwined, illuminating the entire System Space with a doomsday scene.

Lin Feng bathed in the sea of lightning, allowing the destructive power to strike him repeatedly.

His skin cracked inch by inch, blood splattered, yet quickly healed under the nourishment of Devilish Qi.

His bones groaned under the hammering of the lightning, unable to bear the burden, yet became even tougher after breaking and reforming.

The Bottleneck of the Rahu Demonic Body began to loosen under the baptism of this violent Lightning Tribulation.

After an unknown period, the tribulation clouds in the sky also seemed to have exhausted their power and began to slowly dissipate.

A full hundred Lightning Tribulations!

When the last golden lightning bolt, as thick as a water cylinder, struck down, Lin Feng finally could not hold on and was violently smashed into the ground, leaving a bottomless giant pit.

Smoke and dust filled the air.

A moment later, a figure slowly flew out of the pit.

It was Lin Feng.

At this moment, although his clothes were tattered and his hair scorched black, his eyes were astonishingly bright.

The wounds on his body, caused by the lightning strikes, had long healed, and the surface of his skin shimmered with a faint, metallic black glow, as if it had condensed into a tough Demonic Body.

The Rahu Demonic Body, second layer, was complete!

Lin Feng inwardly examined his Dantian.

Within his Dantian Qi Sea, the originally faint green Golden Core had now completely transformed.

It was no longer simply green, but displayed a noble and mysterious purple-gold color, its surface smooth and flawless, with Dao charm subtly flowing.

Among Golden Cores, purple-gold is the ultimate!

"Purple-Gold Golden Core!" Lin Feng rejoiced in his heart.

Not only had he achieved perfect Foundation Establishment, but now he had also formed a perfect Purple-Gold Golden Core.

He couldn't help but feel curious about how much his strength had increased.

Lin Feng pondered for a moment and thought of a test subject.

With a thought, a black light flew out from his sleeve, landing on the ground and transforming into an ancient small bell—the East Emperor Bell.

A flash of light from the bell's mouth, and a figure was thrown out in a disheveled state, it was Lu Yunfeng, who had been trapped inside the bell for a long time.

At this moment, Lu Yunfeng's aura was extremely weak, his spiritual power dissipated throughout his body, his eyes lifeless, with only a thread of life remaining.

Lin Feng flicked a finger, and a pure spiritual power entered Lu Yunfeng's body, temporarily stabilizing his injuries.

"Wake up!" Lin Feng commanded coldly.

Lu Yunfeng shivered, his unfocused eyes gradually sharpened, and upon seeing Lin Feng, his eyes instantly filled with fear.

"Senior... Senior..." His voice was hoarse, and his body trembled uncontrollably.

Lin Feng couldn't be bothered with idle talk and directly pulled out a Talisman from his Storage Pouch.

This Talisman was entirely crimson, with intricate golden patterns drawn on it, emitting strong spiritual power fluctuations.

It was the same Advanced Spirit-Descending Talisman he had given to Xiang Zhili!

Lin Feng slapped the Talisman onto Lu Yunfeng's forehead.

"Buzz!"

The Talisman transformed into a red light and merged into Lu Yunfeng's body.

Lu Yunfeng's aura began to surge madly!

Qi Refining Perfection... Foundation Establishment Early Stage... Foundation Establishment Late Stage... Foundation Establishment Perfection... Core Formation Early Stage!

In the blink of an eye, Lu Yunfeng's Cultivation was forcibly raised to the peak of Core Formation Middle Stage, just a hair's breadth away from Core Formation Late Stage.

Lin Feng frowned slightly.

"Still not enough."

He formed hand seals, and several strange incantations were successively cast into Lu Yunfeng's body.

These were all forbidden techniques he had exchanged from the System that overdrafted life and burned potential.

Lu Yunfeng let out a shrill scream, his body convulsed violently, and blood oozed from all seven orifices.

His aura, building on the Core Formation Middle Stage, surged again!

Core Formation Late Stage!

Core Formation Perfection!

False Nascent Soul Realm!

Finally, Lu Yunfeng's aura barely stopped at a level infinitely close to Nascent Soul, yet not truly forming a Nascent Soul, almost reaching the limit of spiritual power that a Core Formation Cultivator could unleash.

"Condense a shield, defend with all your might!" Lin Feng commanded, his voice devoid of emotion.

Lu Yunfeng's mind was now controlled by Lin Feng, and upon hearing the command, he instinctively mobilized the surging spiritual power within his body, condensing an incredibly thick purple spiritual power shield in front of him.

Spiritual light shone on the shield, indicating its strong defensive power.

Lin Feng's expression was calm, he pointed his fingers like a sword, and casually swiped forward.

A condensed Five Elements Sword Qi, silently shot out.

"Whoosh!"

The Five Elements Sword Qi struck the purple shield.

Lu Yunfeng's fully activated shield lasted for less than a breath of time before letting out a helpless wail, shattering inch by inch like fragile glass!

The Sword Qi's momentum remained undiminished, directly piercing through Lu Yunfeng's chest.

"Puff!"

Lu Yunfeng was struck hard, spitting out a mouthful of blood, his body flying backward like a kite with a broken string, heavily crashing onto the ground.

A fist-sized blood hole in his chest was shocking to behold, and his aura instantly weakened, clearly not long for this world.

Lin Feng nodded slightly.

A casual strike could severely wound a False Nascent Soul Cultivator pushed to their limit.

His current strength, among Core Formation Cultivators, was probably unrivaled.

Even against an Early Stage Nascent Soul, he might not be without a chance to fight.

He waved his hand, and the dying Lu Yunfeng was once again taken into the East Emperor Bell.

This guy wasn't going to die just yet; keeping him might still be useful.

With the test complete, Lin Feng was in a great mood.

His figure flickered, and he left the System Space, returning to the quiet room of his Immortal Cave.

Pushing open the stone door of the quiet room, he saw Han Yunzhi guarding outside the door.

Upon seeing him emerge, the girl's face immediately showed surprise.

"Young Master! You finished your seclusion so quickly?" Han Yunzhi felt the powerful aura emanating from Lin Feng, which was completely different from before, and her voice carried a hint of joy.

"Mm," Lin Feng smiled and nodded.

He looked at Han Yunzhi, his gaze lingering on her for a moment.

This girl's Aptitude was quite good.

Lin Feng's heart stirred, and he spoke, "Yunzhi, since your Foundation is stable, you are sufficient to attempt Foundation Establishment."

Upon hearing this, Han Yunzhi's delicate body trembled, a hint of anticipation flashing in her bright eyes, along with some apprehension: "Young Master... I... can I?"

"Why not?" Lin Feng smiled, "How about today? I will be your Protector and help you Foundation Establishment."
