I run a casino in the immortal realm.

The back mountain of the Heavenly Demon Sect, which was originally a lush and precipitous mountain range, has now been turned into a dead land.

A turbulent vortex of spiritual energy, like a giant millstone, enveloped the entire back mountain.

Before this pure and wild power of heaven and earth, nothing can remain intact.

The ancient trees, upon contact with the spiritual energy storm, were instantly reduced to dust, leaving not even a speck of wood behind.

The massive black boulder, weighing tens of thousands of kilograms, was as fragile as tofu, weathering and dissipating silently.

One hundred and fifty elite cultivators from the Heavenly Demon Sect sat cross-legged in a circle at the edge of the Spirit Wind Eye.

This was a painful yet pleasurable ordeal.

The spiritual energy, so pure it was almost liquid, mixed with a violent sense of spatial tearing, relentlessly washed over everyone's body.

This kind of cleansing is not gentle nourishment, but rather like countless steel files scraping hard across the meridians and bones.

Those with weaker willpower began to tremble involuntarily, and fine beads of blood seeped from their skin.

But as long as you can endure this excruciating pain, it's also obvious that the benefits are significant.

Within those forcibly widened meridians, spiritual energy surged like a rushing river, frantically converging towards the dantian, and everyone's cultivation level was rising steadily at a visible speed.

Besides enduring the tearing of spiritual energy, they also had to constantly be mindful of the lightning strikes that occasionally came down from the purple vortex above their heads.

Late at night on the third day.

The normally rotating spiritual energy tide suddenly shifted without warning.

A powerful undercurrent emanated from the center of the vortex, sweeping directly towards the location where Zheng Yifei and the others were.

Although Zhao Ling possessed exceptional talent in alchemy, her physical strength and combat instincts were the weakest among the five. The moment that dark current swept past, the protective aura around her shattered like paper. She cried out in alarm as her body was uncontrollably swept into the air, heading straight for the center of that meat grinder-like vortex.

"Zhao Ling!"

At the critical moment, Zheng Yifei and Su Wanqing opened their eyes at the same time.

Without the slightest hesitation, the two attacked simultaneously from the left and right. Su Wanqing drew her longsword, and the icy sword energy transformed into a white streak, forcefully slicing through the violent airflow beside Zhao Ling;

Zheng Yifei then pushed the Five Elements spiritual power to its limit, reached out with his right hand, and grabbed Zhao Ling's ankle.

"Get down here!"

Zheng Yifei's forehead veins bulged, and his feet were firmly planted on the charred rocks, leaving two deep pits in the rock.

Su Wanqing also grabbed Zhao Ling's wrist, and the two of them worked together to pull Zhao Ling back from mid-air, despite the enormous pulling force of the spiritual energy tide.

The three of them crashed heavily to the ground. Zhao Ling's face was deathly pale, and she was panting heavily, her eyes filled with lingering fear. She was just a hair's breadth away from being swept into the eye of the storm and turned into a cloud of blood mist.

"Stay calm, focus your mind, and don't get distracted!"

Zheng Yifei wiped the blood from the corner of his mouth and whispered.

Zhao Ling nodded, quickly swallowed a pill to stabilize her meridians, and sat cross-legged again.

Time passed day by day amidst the agonizing torment.

tenth day.

Su Wanqing, who had kept her eyes tightly closed, suddenly heard a clear sword cry emanating from within her body. The turbulent spiritual energy around her seemed to be drawn by something, rushing wildly into the top of her head. A moment later, a powerful pressure belonging to the mid-stage of the Golden Core realm emanated from her.

She was the first to break through!

Su Wanqing's breakthrough is like a signal.

Immediately afterwards, a soft medicinal fragrance emanated from Zhao Ling's body, and her aura suddenly intensified.

The sounds of bones cracking also came from Li Jianfeng and Wang Changsheng's bodies one after another. Within half an hour, the three of them successively entered the mid-stage of the Golden Core realm.

However, Zheng Yifei, the core of the team, remains completely silent.

The five golden cores within his body were like five bottomless pits. No matter how much spiritual energy poured in, it was greedily devoured by them, yet they could never reach the critical point of qualitative change.

The drawbacks of cultivating all five elements simultaneously became clear at this moment; the energy he needed to break through was five times or even more than that of an ordinary person.

On the fifteenth day, a muffled rumble finally came from Zheng Yifei's body. All five golden cores swelled up, and more intricate patterns appeared on their surfaces. He had just broken through to the middle stage of the Golden Core realm.

On the twentieth day, Su Wanqing, Zhao Ling, Li Jianfeng, and Wang Changsheng broke through again with unstoppable momentum, entering the late stage of the Golden Core realm.

On the thirtieth day, the auras of these four people had reached a peak, reaching the completion of the Foundation Establishment stage, and they were only one step away from the Nascent Soul stage.

Without hesitation, they took out the top-grade Breakthrough Pill refined by Zhao Ling, swallowed it in one gulp, and began to break through to the Nascent Soul Dao with all their might.

At this time, Zheng Yifei had just broken through to the late stage of the Golden Core realm.

Zheng Yifei opened his eyes and looked at the four people around him who were doing their best to form their Nascent Souls. His brows furrowed tightly.

Nineteen days left.

If he continues at this steady pace of absorption, he will at most break through to the Golden Core Perfection stage this time.

With the aid of top-grade Breakthrough Pills and the Law Fragments from the Spirit Wind Eye, Su Wanqing and the others are almost certain to break through to the Nascent Soul stage.

"not enough……"

Zheng Yifei gritted his teeth inwardly.

This opportunity of the Nascent Soul Tribulation is a once-in-a-millennium event. If he misses it, given the nature of his Five Elements Spiritual Roots, it will take him at least several decades or even hundreds of years to accumulate enough experience to break through to the Nascent Soul stage in the outside world.

But will the Xuantian Sect give him several decades?

Qin Cang, that old fox, will definitely not let him go. Once the Heavenly Tribulation ends, there will inevitably be a bloody battle between the Xuan Tian Sect and the Tian Mo Sect.

In that level of meat grinder, the difference between a Golden Core cultivator at perfection and a Nascent Soul cultivator at the early stage is that of cannon fodder versus a chess player.

We must find another way!

Zheng Yifei raised his head and stared intently at the purplish-red tribulation cloud in the sky.

He suddenly recalled Ye Tianqiong's words: "The tribulation of lightning is blind... If you can't withstand it, you will die and your cultivation will be destroyed. If you can withstand it, the power of destruction and rebirth contained in the tribulation will give your physical body and cultivation a qualitative leap. You will be invincible in combat against those of the same level, and you will be able to fight against those of higher levels. You may even be able to comprehend the laws of lightning."

The tribulation of lightning is a double-edged sword.

The pressure from Qin Cang was like a sharp blade hanging over Zheng Yifei's head, forcing him to take a gamble.

Just then, a dark red lightning bolt as thick as a bucket suddenly veered off course from the center of the sky, like a raging blood dragon, carrying an aura of destruction, and struck straight at Su Wanqing, who was attempting to break through to the Nascent Soul stage.

Su Wanqing is currently at a critical moment in breaking through her cultivation level, and her perception of the outside world has almost dropped to zero, making it impossible for her to escape.

"Well done!"

"The Spiritual Finger!"

This martial art, originally used to injure people by striking pressure points, was now being used by Zheng Yifei as a lightning rod.
