Upon seeing this message, Gu Jian was slightly taken aback.

It turned out to be the legendary double pupils.

As a time traveler, Gu Jian had read many novels and naturally knew what double pupils were.

This is an existence even more powerful than the Supreme Bone, defying the heavens.

It can not only enhance combat power, but also improve talent and potential.

Moreover, what's in front of us isn't an ordinary case of double pupils.

It possesses a demonic quality; it is the first double pupil in the vast universe!

"Possessing demonic double pupils? That looks incredibly powerful, perfect for me."

Gu Jian muttered to himself, a smile appearing on his face.

The little devil Ling'er also saw this pair of peerless ancient double pupils.

She flapped her demonic wings behind her, and an excited expression appeared on her delicate, cute, and bewitching face. "Eeya, congratulations, Master."

"The ancient double pupils are incredibly powerful! They can not only make the master stronger, but also enhance the master's talent."

"Master, quickly merge and become stronger!"

"Okay. Little Yiya."

Gu Jian nodded, using the secrets of the Longevity Demon Palace to control the Ancient Double Pupils to move towards him.

Then, the peerless demonic eye transformed into a beam of light and shot into his eyes.

Gu Jian's body stiffened.

In that instant, Gu Jian's eyes held the interplay of yin and yang, the rise and fall of the sun and moon.

At the same time, a phantom figure resembling a human emperor slowly rose from the world in Gu Jian's eyes.

After the fusion of the double pupils, a powerful force entered Gu Jian's body, causing his cultivation to rapidly improve.

The Ninefold Perfection of the Mysterious Realm of Life and Death.

One cycle of reincarnation!

Double Reincarnation!

Triple Reincarnation!

...

boom!

Gu Jianshuang's long, white hair danced wildly.

When the breath stops getting stronger.

His cultivation level reached the perfect stage of the third level of reincarnation.

At the same time, Gu Jian seemed to have faintly touched upon some kind of power of rules.

With a thought, Gu Jian activated his spiritual power, and his body, which was standing in front of the Tomb of Gods and Demons, slowly flew up.

"After reaching the Reincarnation Realm, one can fly through the air. This feeling is truly wonderful!"

A smile appeared on Gu Jian's face as he used his spiritual power to fly around the Longevity Demon Palace.

This was his first time flying, and he was very happy.

In addition, his talent was further enhanced due to the fusion of double pupils.

Gu Jian gained a deeper understanding of the laws and artistic conceptions, as well as the true meaning of cultivation.

The benefit was that his mastery of the Five Elements Sword Intent was improved once again.

Like other fist intents, sword intents, etc., sword intents have a total of five levels from low to high.

Now, Gu Jian has reached the fourth level of perfection.

For an ordinary young sword cultivator, even cultivating sword intent to the first level of perfection would make one an extraordinary sword prodigy.

To reach the second level is to be an unparalleled genius.

The third level is known as the "monster".

The fourth level is the most extraordinary of all.

Gu Jian reached the fourth level of perfection in just a few months!

However, this was normal for Gu Jian.

After all, he has extraordinary talent.

Let alone reaching the fourth level of perfection, even raising sword intent to the fifth level of perfection doesn't take much time.

Your swordsmanship will reach ever higher levels in the future!

"If I raise my sword intent to the fifth level of perfection, the power of my swordsmanship will increase by at least ten times compared to before."

"Furthermore, after merging with the double pupils, I also comprehended the fist intent, which is the Five Elements Fist Intent!"

"The Five Elements Fist Intent can enhance the power of the fist technique. If the level is increased, the power of my 'Demon Dragon Flame Overlord Fist' will also be further enhanced."

What is cultivation? It's as simple as eating and drinking.

Gu Jian's current situation is like this.

After glancing at the dense chaotic energy within the Immortal Demon Palace, Gu Jian decided to absorb another wave.

Since his cultivation has already improved by three levels after merging with the double pupils, it is not suitable to improve it too much further.

However, in Gu Jian's opinion, raising the level by one or two more levels shouldn't be a big problem.

With that in mind, Gu Jian flew towards the plaza where the Longevity Demon Palace was located.

Under the adoring gaze of the little devil Ling'er, Gu Jian landed in the center of the Eternal Life Demon Palace.

There was a damp feeling around us.

Gu Jian knew that it was caused by the spiritual energy being too concentrated, which almost liquefied.

At this moment, Gu Jian's body was almost submerged in the vast ocean of spiritual energy.

He sat down cross-legged on the spot, placed his hands on his dantian, and activated the Chaos Suppressing God Technique without hesitation.

Gu Jian's body emitted light, and a sacred yet evil aura continuously spread from him.

The next instant, the pure chaotic energy around him swirled towards him and was absorbed by him.

It's unclear how long this lasted.

Gu Jian's aura intensified further.

When Gu Jian opened his eyes.

An aura of the sixth level of reincarnation emanated from Gu Jian.

"He's actually reached the sixth level of reincarnation?"

Feeling his own power, Gu Jian was stunned.

He originally thought he could only improve by two levels at most, but now he has improved by three levels.

It should be noted that, as a divine-level demonic technique, the Chaos Suppressing God Technique can compress spiritual power infinitely.

Compared to people of equal cultivation level.

With each advancement in his cultivation level, Gu Jian absorbed more than a hundred times the spiritual energy of others.

And now, it has been upgraded three times in a row?

Gu Jian realized that he had underestimated the density of the chaotic energy in the Longevity Demon Palace.

At this moment, the chaotic energy within the Immortal Demon Palace had thinned somewhat.

Gu Jian felt that the spiritual energy in his body was extremely abundant, and every cell in his body was filled with explosive power.

"It seems I need to focus on consolidating my cultivation level from now on."

"A towering building rises from the ground; only by perfecting each realm can one become increasingly powerful in the later stages, crushing everyone of the same era!"

Gu Jian is a demonic cultivator, but he also has high standards for himself.

Gu Jian did not want a situation where unrestrained improvement would ultimately lead to an unstable foundation.

Gu Jian was quite satisfied that he had reached the sixth level of reincarnation in such a short time.

This was something I wouldn't have dared to even dream of before obtaining the Immortal Demon Palace.

In addition, he cultivated a divine-level demonic art.

Even if Gu Jian doesn't use the Supreme God-Demon Bone, the God-Demon Devouring Body, or the power of the Ancient Double Pupils.

Based on his own combat strength alone, he is probably already comparable to a Nirvana Realm expert.

He also possesses the immortal-level "Demon. Sword Drawing and Heaven-Slaying Technique".

Even if he were to face someone at the sixth level of Nirvana, he was confident he could use that opportunity to kill him.

"Master, you're amazing! Master, have you reached the sixth level of Reincarnation yet?"

The little devil Ling'er flew over, her enchanting eyes sparkling like stars.

Gu Jian patted her head and smiled, "Not bad, little Yiya."

In just a few months, it has become this powerful.

Gu Jian himself found it hard to believe.

The speed of this improvement is terrifying.

But Gu Jian knew that this was all brought about by the Immortal Demon Palace.

Next, he will continue to earn longevity points.

Of course, we also need to capture Ye Chen!

Thinking of Ye Chen, Gu Jian asked the little devil Ling'er, "Ling'er, do you have a way to help me find Ye Chen?"

"Eeya, Master. It's very simple. Ling'er can help Master explore by consuming 10,000 Longevity Points!"
