641: Chapter 641 140 Hertz!

"As expected, my Mental Energy has dropped quite a lot."

Qin Yan murmured, his heart aching as he looked at that number.

From two hundred and five Hertz down to one hundred and forty Hertz—a full sixty-five Hertz had dropped.

These sixty-five Hertz were the result of his hard-earned Breakthrough, and seeing them vanish in an instant, it would be a lie to say he wasn't pained.

However, Qin Yan quickly adjusted his mindset.

"It doesn't matter. As long as my Shadow Clone goes to comprehend the Darkness Profundity, it will only take a few days for my Mental Energy to recover."

Previously, when he was comprehending the Darkness Profundity, it hadn't taken long for it to increase by five Hertz, and that was from two hundred to two hundred and five.

One must realize that the further one progresses in cultivating Mental Energy, the harder it becomes to improve.

The difficulty of increasing from two hundred Hertz to two hundred and five Hertz was comparable to increasing from one hundred Hertz to one hundred and ten Hertz.

This was also why Qin Yan's Mental Energy still had one hundred and forty Hertz remaining after being split in half, rather than just over a hundred.

"Clone, you should Cultivate first during this time and increase your Mental Energy."

Qin Yan said as he looked at the Shadow Incarnation.

The Shadow Incarnation nodded.

"Understood."

His voice was as cold as ever.

After speaking, his body transformed into a streak of black light and vanished into Qin Yan's body.

The black light traveled through the Meridians and arrived at the Blood Demon Nest in the blink of an eye.

Deep within the Blood Demon Nest, the demonic qi black hole was slowly rotating.

Above the black hole, chains formed from the condensed Darkness Profundity hovered in the air, emitting a dark, somber glow.

Runes flickered in and out of sight, and laws flowed incessantly.

The Shadow Incarnation's figure appeared beneath the demonic qi black hole.

He looked up at those darkness chains.

A flash of excitement gleamed in those pitch-black eyes.

For the Shadow Incarnation, the Darkness Profundity was the best possible resource.

The Shadow Clone sat cross-legged and closed his eyes, beginning to sense the chains of Darkness Profundity floating in the air.

The mysterious runes on those chains became incredibly clear in his eyes.

His Mental Energy extended like tentacles, wrapping around those runes and greedily absorbing the Profound Truths contained within.

As the Shadow Clone gained insights, Qin Yan could clearly feel his own Mental Energy rapidly increasing!

One hundred and forty-one Hertz, one hundred and forty-two Hertz, one hundred and forty-three Hertz...

Almost every few minutes, Qin Yan's Mental Energy would increase by one Hertz.

That speed was simply incredible.

"Is this the terrifying power of the Shadow Clone?"

Qin Yan felt the wonderful sensation of his Mental Energy growing rapidly, his heart filled with shock.

The Four Secrets of the Heavenly Demon were originally created by the Heavenly Demon, who was the ultimate master of the Dao of Darkness, with an understanding of darkness that surpassed all predecessors and would never be reached by those who follow.

The four secret techniques he created, especially the Shadow Clone and Soul Dominion, pushed the arts of darkness to their absolute limit.

The Shadow Clone itself was an Incarnation of darkness, an existence condensed from pure dark Mental Energy.

Its affinity with darkness far exceeded that of any Cultivator who practiced darkness-attribute techniques.

It could be said that the Shadow Clone was a born super Genius in the cultivation of the Dao of Darkness.

Especially with the enhancement of the Darkness Profundity, it was equivalent to providing this Genius with an inexhaustible treasury.

Whatever he wanted, the treasury had; whatever he wanted to comprehend, the Profound Truth was presented directly before him.

Under these conditions, the Shadow Clone's cultivation speed had reached a superhuman level.

At this rate, restoring Qin Yan's Mental Energy to its original strength would be a piece of cake.

Not to mention two hundred and five Hertz; even breaking through further would not be difficult.

In fact, it wouldn't be long before his Mental Energy reached three hundred or even over four hundred Hertz!

The day his Mental Energy caught up to his Body Refining and Qi Refining was just around the corner.

Soon, the night passed.

The morning sunlight spilled through the window of the Immortal Cave, casting a golden glow on the floor.

Qin Yan opened his eyes and opened his panel.

[spirit: 180 Hertz]

"One hundred and eighty Hertz."

Qin Yan looked at that number, the corners of his mouth curling up slightly, his joy beyond words.

In one night, it had risen from one hundred and forty Hertz to one hundred and eighty Hertz, a full forty-Hertz increase.

At this rate, in another day or two at most, his Mental Energy would return to its Peak level.

Qin Yan's mood at this moment was indescribably wonderful.

With the Shadow Clone "cheat" available, he no longer had to worry about his Mental Energy cultivation.

"Since the Shadow Clone has finished its initial cultivation, it's time for me to get down to business."

Qin Yan retracted his focus.

The Shadow Incarnation was continuously absorbing Darkness Power within the Blood Demon Nest, and its Mental Energy was steadily increasing.

This matter no longer required his concern.

The Clone would Cultivate and grow on its own.

And then it would drive his own growth.

As for his main body, there were more important things to do.

With a thought from Qin Yan, the Five Elements light orb in his mind suddenly lit up with a dazzling radiance.

The light orb was woven from five colors—gold, green, blue, red, and yellow—rotating slowly and emitting a mysterious aura.

This was the entrance to the Five Elements Yin-Yang Hunyuan Tower.

Immediately after, Qin Yan felt his spirit being sucked into the light orb, and after a bout of dizziness, the scene before him underwent a world-shaking change.

In the next moment, Qin Yan found himself inside the fifty-first floor of the Five Elements Yin-Yang Hunyuan Tower.

That's right, he was here to challenge the Five Elements Yin-Yang Hunyuan Tower.

As long as he cleared the sixtieth floor, he could obtain a large amount of Profound Truths again!

Furthermore, he could obtain a Divine Ability that would allow Supreme-level Concepts to coexist within his body!

Qin Yan took a deep breath and looked at the Guard Figure in front of him.

He took a step forward, entering the battle range.

The Guard Figure "came to life," its body flickering as it rushed toward Qin Yan like a ghost.

Its speed was startlingly fast, leaving a blurred afterimage in the air as it reached Qin Yan in the blink of an eye.

Qin Yan didn't even look as he threw a punch!

His fist carried a terrifying, destructive power.

His 1.254 million Cal of Basic Blood Qi erupted without reservation at this moment.

Where the wind of the punch passed, the air let out a sharp, explosive boom.

"Bang—!"

A dull thud rang out.

The Guard Figure's body was instantly smashed into fragments.

It turned into specks of energy light and dissipated into the air.

...

Following that, Qin Yan advanced with irresistible force.

On the fifty-second floor, the Guard Figure held a golden longsword, its Sword Intent sharp and its sword light like a rainbow.

Qin Yan swept out with his spear, the wind of the spear whistling as it directly sent the Guard Figure flying, sword and all, crashing into the wall and turning into fragments.

On the fifty-third floor, the Guard Figure was surrounded by flames like a man of fire, breathing out scorching blazes.

Qin Yan thrust his spear, ice and fire intertwining, cold and heat clashing, directly suppressing the fire man's flames until they were completely extinguished.
