My low-key cultivation of immortality was discovered by the emperor in my diary.

Above the sky, dark clouds rolled like ink, and the lightning tribulation intensified.

The lightning bolts grew increasingly fierce, and the Heavenly Net Umbrella could no longer withstand them.

The original white background with gold patterns on the umbrella surface is no longer visible. The charred lightning marks are crisscrossed and have even pierced through the umbrella surface, leaving small holes.

A crack instantly spread out, followed by an even more violent bolt of lightning that crashed down, tearing the canopy of the Heavenly Net Umbrella to shreds, leaving only the lonely ribs swaying in the wind, a pitiful sight.

Chu Lengyu remained expressionless as she put the broken umbrella ribs into her storage bag.

Immediately, an ancient and heavy tortoise spirit shield appeared above her head, with a faint spiritual light flowing over it; it was the tortoise spirit shield that had been prepared long ago.

The shield instantly formed a solid defensive barrier around her, keeping the raging lightning out.

The third round of tribulation lightning ended with a deafening roar.

However, the calamity clouds overhead had not yet dissipated, and the aura emanating from them grew increasingly terrifying, carrying the meaning of annihilation, enough to instantly reduce any mortal being to ashes.

Chu Lengyu looked up at the cloud of tribulation, a look of solemnity flashing in her eyes, but she did not retreat in the slightest.

This is the final test.

She took out the Shennong Herbal Pill, put it in her mouth, and accelerated the recovery of her spiritual power.

She paid close attention to the changes in each lightning bolt, and could roughly estimate the power of the final round of lightning. At this moment, she was calmly calculating how much power she could still have left for the last lightning bolt, and a rare ruthlessness flashed in her eyes.

Today's tribulation of lightning suddenly sounded an alarm bell deep within Chu Lengyu's heart, waking her from her past smooth cultivation.

The path to immortality is never smooth; every step forward is accompanied by corresponding trials and challenges.

She only rose to prominence by taking advantage of the system; she must not slack off, become complacent, or arrogant.

Her real enemy was always herself!

Besides, the stronger a person is, the stronger the tribulation lightning becomes; she should be happy.

Chu Lengyu took a deep breath, clearing her mind of all distractions, leaving only a clear mind.

In the blink of an eye, the ninth-to-last tribulation lightning bolt crashed down with a devastating force.

It was as if the heavens and earth were roaring in anger at this moment, wanting to completely annihilate anything that defied their will!

An unprecedented sense of crisis instantly swept over Chu Lengyu.

But she always remained calm in the face of major events, and did not panic. She stared at the tribulation lightning without any fear.

At the most critical moment, Chu Lengyu used all her strength to engage in a final battle against the lightning tribulation.

The ninth, eighth, seventh...

The raging lightning, like an endless tidal wave, surged wildly across the desolate land, enveloping everything in a dazzling yet terrifying light.

This once silent wilderness now seemed to have transformed into a sea of ​​lightning, with deafening roars echoing from time to time, shaking the souls of everyone present.

The earth trembled incessantly under the power of the lightning tribulation, as if it too could not withstand it.

On the low mountain, although Lü Yun and the others tried their best to stand firm, their bodies still swayed involuntarily with the tremors of the earth in the face of such powerful lightning tribulation. Their faces were as pale as paper, and their eyes were filled with horror.

Fu Wenshen planted his clumsy sword in the ground, gritted his teeth, and struggled to maintain his balance. He stared at the heavy lightning and was stunned.

The power of the lightning tribulation far exceeded his expectations, making him feel a wave of fear. Recalling how he had boasted before that he wanted to help Miss Chu overcome the lightning tribulation, he felt extremely ashamed.

If he were truly placed under those calamity clouds, he probably wouldn't have been able to withstand it for even a moment before turning to ashes and disappearing into the world.

Moreover, Miss Chu once said that this was the Lesser Tribulation of Lightning, implying that there were other tribulations, each more shocking than this!

Because he had been staring at the flashing lightning for so long, Master Lu's eyesight had been severely affected.

He had to turn to the side, rubbing his slightly stinging eyes with both hands to wipe away the tears.

He was so excited that he couldn't speak, his heart filled with admiration and concern for Miss Chu.

He knew that such a tribulation was something that no ordinary person could withstand, yet Miss Chu faced it all alone.

Her courage and strength deeply impressed and inspired him.

Lü Yun and Master Lu were in similar situations, but she was unusually stubborn and refused to look away.

Tears streaming down her face, she gazed into the distance, her voice hoarse as she counted, "Third to last!"

The last three bolts of tribulation lightning were the most intense.

The third-to-last lightning tribulation was so fierce that it resembled a giant dragon roaring out from the depths of the dark clouds, carrying a destructive power capable of shaking mountains and rivers, determined to turn all living beings that stood in its way into ashes.

Its body twisted and contorted in the air, each scale flashing with dazzling electricity, as if it wanted to bring the entire world under its control.

Faced with this terrifying attack, Chu Lengyu showed no fear.

The Tortoise Spirit Shield protected her, with the Bagua pattern flowing endlessly on it, radiating a dazzling light, as if it contained the ultimate truth of heaven and earth.

As the lightning tribulation crashed down, the entire world seemed to change color.

The dragon-like lightning, carrying the force of an overturned mountain, crashed heavily onto the Turtle Spirit Shield.

Surprisingly, the Turtle Spirit Shield did not break or retreat. Instead, it shone brightly, and the Bagua pattern spun rapidly, as if infinite power was surging and intertwining within it.

The power of the tribulation lightning was resisted and neutralized one by one, leaving only a loud roar before the lightning dissipated into nothingness.

However, this magical artifact was also severely damaged, and the Bagua pattern faded.

The penultimate lightning tribulation was even more powerful than the previous one. It was like the wrath of the heavens, carrying a terrifying power that could destroy everything and devour all things, and once again launched a fierce attack on Chu Lengyu.

This tribulation of lightning contained endless violence and ravages, as if it would engulf everything in the world and reduce it to nothingness.

Faced with this even more ferocious attack, Chu Lengyu's heart was stirred, but her eyes became even more determined.

At this moment, there is no way to retreat; only by fighting with all our might can we have a glimmer of hope.

So she took a deep breath, mobilized all her spiritual power, and poured it into the Turtle Spirit Shield.

The Bagua patterns on the shield seemed to come alive at that moment. They spun faster and faster, and the light they emitted became more and more dazzling, as if they wanted to gather all the power together to resist this devastating impact.

However, even with the Turtle Shield being so tough, it seemed somewhat powerless in the face of such terrifying power.

The light on the shield began to flicker, and Chu Lengyu could feel the immense pressure emanating from it. Her body trembled slightly from the impact of this force.

Finally, the lightning dissipated, and the Turtle Shield barely withstood the attack.

But by then it was already badly damaged, and even if materials were found to repair it later, it would take many years to fully recover.

If it were any other cultivator, having finally obtained such a powerful defensive magic weapon, and then seeing it damaged like this, they would probably be heartbroken.

But for Chu Lengyu, the Heavenly Net Umbrella and the Turtle Spirit Shield were system rewards. She hadn't paid anything for them and regarded them purely as tools for overcoming tribulations, so she didn't feel particularly bad about them.

The final tribulation lightning bolt was the purest lightning power in the world.

It was untouched by dust and impurities, carrying only the purest and truest intent of destruction and rebirth, like divine punishment descending, mercilessly sweeping towards Chu Lengyu.

Faced with this final blow, Chu Lengyu made a surprising decision.

She abruptly released her grip on the Turtle Spirit Shield, causing it to self-destruct in mid-air. A powerful surge of spiritual energy erupted instantly, successfully blocking the lightning tribulation for a moment.

Under the cover of the magic weapon's self-destruction, the Unrivaled Sword had quietly appeared in her hand, its blade gleaming with cold light and incomparably sharp.

Chu Lengyu tightened her grip slightly, concentrating all her spiritual power into the spirit sword. She gazed at the final bolt of tribulation lightning, her eyes filled with both determination and anticipation.

At this moment, the sword and the man seemed to become one, facing this final challenge together.

Finally, she unleashed her final strike!

This sword strike was fierce and powerful, condensing all her cultivation and will, carrying an indomitable spirit, and pierced straight towards the tribulation lightning.

Sword light and lightning intertwined and collided in the air, bursting out with dazzling light and deafening roar!

At that moment, the world lost its color, and even the greatest sounds were silent.
