Infinite Evolution

As the saying goes, there are no permanent friends or permanent enemies, only permanent interests!

This sentence couldn't be more appropriate now.

After reaching negotiations and determining their common interests, Chu Xun and the others finally "turned enemies into friends" with the old Black Mountain monster. Although they were actually wary of each other, they at least maintained sufficient respect on the surface. Sincerity and goodwill.

So next, Chu Xun and others unlocked the Zhoutian Star Dou Formation and returned the Black Mountain Old Demon to the Yin and Yang Realm. At the same time, as he promised, the Black Mountain Old Demon mobilized a large number of soul nightmares to protect the Bird Emperor. A little bit of true spirit, coupled with the help of the naughty child's power of time, finally saved the Bird King's last glimmer of hope.

Of course, this is thanks to the fact that the Bird King only has a little bit of his true spirit left, and his power is extremely weak, even almost non-existent, so the naughty kid didn't use much power to freeze his time. Otherwise, I'm afraid that with the naughty kid's current cultivation strength, he might not be able to keep the Bird King.

This can be considered a great blessing among misfortunes.

"Now that everything is settled, when will you help me break the formation?"

Seeing the naughty kid freezing the time of the Bird King's true spirit and taking it into his own divine realm, the old Black Mountain demon's eyes suddenly flashed with a gleam, and then he smiled at Chu Xun and the others: "I I have been trapped in this Yin and Yang world for hundreds of millions of years, and I am really getting tired of it. If you can, could you please let me out of this cage as soon as possible?"

The power of time is a powerful force that everyone knows, but it is too unfamiliar and extremely difficult to understand. But the young-looking guy in front of him was actually proficient in the power of time. As a result, his expectations for Chu Xun and others to be able to break the formation were even greater.

"We also hope to go to the underworld as soon as possible. After all, the news of our attack should have been sent back to heaven. If we don't show up for too long, I'm worried that there will be other changes."

Hearing what the old demon from Black Mountain said, Chu Xun nodded and said, "Let's go and see the underworld seal first, and then make a decision!"

"good!"

Hearing Chu Xun's words, the old Black Mountain demon immediately waved his right hand impatiently, and then saw the Black Mountain City suddenly shooting out at an extremely fast speed, flying towards the depths of the mist.

While heading to the location of the seal, Chu Xun and others also chatted a lot with the old demon from Montenegro about the true spirit, soul and the Yin and Yang Realm. This also gave Chu Xun and others a deeper understanding of the soul. .

Although they had heard about the true spirit before, it was not until this moment that they had a true understanding of the true spirit.

If the soul is the core of a person, then the true spirit is the core of the soul.

The true spirit is a mysterious and mysterious thing. It can be said that it is a power that is almost impossible to perceive and control, but it cannot be erased. Even with the angry killing sword energy, after annihilating a person's soul, it is difficult to completely destroy that person's true spirit, let alone the power of other people.

According to Angry and others' understanding, the only person in the world who can control the power of the true spirit is one person and one thing. This person refers to the old Black Mountain demon who was born in the Yin and Yang world and was born from the convergence of countless soul fragments and true spirits. It's just that he can control the true spirit only because of instinct. He can't teach others at all, and he can only swallow the power of the true spirit. He can't reshape the true spirit into a soul, nor can he keep the true spirit for too long.

And that so-called thing is the Book of Heaven among the three books of heaven, earth, and man. Nowadays, the Heavenly Court is using the power of the Heavenly Book to preserve a little bit of the true spirit of the countless powerful people who participated in the Battle of the Gods in the Gods List. In this way, even if someone dies in the Battle of the Gods, even if his soul is destroyed, the Heavenly Court can use a bit of the true spirit in the Gods List to reshape that person's soul and bring him back to life.

The only pity is that the Bird King's true spirit is no longer complete, so this list of gods is of no use to him.

"True spirit..."

After listening to the words of the old demon from Black Mountain, Chu Xun seemed to suddenly have a flash of light in his mind. However, before he could catch the light, a wave of energy so violent that it surged like a huge wave of the ocean knocked him out of his state of contemplation. He woke up with a start, and the aura naturally passed away.

At the same time, Chu Xun couldn't help but frown.

He always felt as if he had missed something very, very important!

However, although he felt regretful at this moment, Chu Xun could no longer care so much because his attention had been attracted by the energy vortex far ahead that occupied the entire world!

Obviously, that extremely huge, seemingly boundless energy vortex is the only passage to the underworld!

It's just that the huge energy vortex at this moment is shrouded and shackles by countless black chains, and where the endless black chains exuding a terrifying aura are connected, there is a book that exudes a faint golden light and does not look like it. It's not very thick, and the book with two ancient words written on it is like a lock, connecting all the black chains together, and blocking the entire transmission channel at the same time!

Although Chu Xun and others did not recognize those two ancient characters, at a glance, they immediately understood the meaning of those two characters.

Book of people!

The Three Books of Heaven, Earth and Man, the Book of Man in charge of the underworld and the way of reincarnation!

Buzz!

As Chu Xun saw Ren Shu, two powerful forces in his body seemed to be awakened by Ren Shu's aura, and then waves of extremely terrifying aura surged out of Chu Xun's body and turned into black. One green and two rays of light soared directly into the sky from Chu Xun!

But at this moment, the glazed bodhi tree in Chu Xun's body also shone brightly, and stirred up glazed lights one after another, which merged into one of the black radiances. At the same time, part of the cyan radiance also separated and was suppressed. above the black light.

boom!

The next moment, the black radiance was completely suppressed, leaving only the cyan radiance that rushed out of Chu Xun's body and turned into the shadow of the Chaos Bell. It trembled violently, and bursts of earth-shattering bell tolls came from it, and even trembled out. Waves of blue sound waves swept in all directions.

And as the cyan sound wave swept across, the book linked by countless black chains also shone brightly, as if it was touched by the power of the Chaos Bell.

Not only that, among the countless black chains that were shackled in the transmission channel at this moment, several black chains suddenly shot out, turning into ferocious and terrifying black dragons, biting towards Chu Xun and others!

"Damn it!"

Seeing that the underworld seal had already launched a counterattack before he and others took action, Chu Xun's expression suddenly changed.

But at this moment, the old Black Mountain demon suddenly took action, and then saw the entire Black Mountain City suddenly accelerate and hit the black dragons hard, knocking them back directly, causing them to turn into human beings again. A series of black chains were tied to the seal.

"So strong!"

Seeing this scene, the pupils of Chu Xun and others shrank instantly.

They just felt an extremely powerful aura from the black dragon, even comparable to the terrifying aura of killing three corpses. However, such a terrifying black dragon was easily knocked back by the Black Mountain City, and this Black Mountain City was No damage at all. One can imagine how terrifying the old demon of Black Mountain, a super old demon who has practiced in the Yin and Yang world for hundreds of millions of years and devoured endless soul nightmares, is!

Thinking of this, Chu Xun and others couldn't help but feel a sense of fear in their hearts.

If the Black Mountain Old Demon hadn't been trying to save their lives from the beginning, and if their Zhoutian Star Formation happened to restrain the Black Mountain Old Demon so that it couldn't easily hit them, I'm afraid they would have been there by now. This old Black Mountain demon suffered a great loss, and even died at the hands of this guy!

"See, this is the power of the seal!"

Seeing the frightened and frightened expressions of Chu Xun and others, the old Black Mountain demon took a deep breath and said: "Once the power of this seal is fully activated, the nine hundred and ninety-nine souls on this seal will turn into nine hundred and ninety-nine souls." One hundred and ninety-nine black dragons, each of them has the same power as the black dragons just now!"

"Not only that, the power of these black dragons can even be combined in one place to exert even more terrifying destructive power. Faced with such power, even I dare not underestimate it. Even if all the black chains are dispatched together, Even if I try my best, I may not be able to sustain it for long!”

"However, this is not the most difficult thing!"

Having said this, the old Black Mountain demon paused for a moment, then pointed at the human book and said: "The most difficult thing to deal with is this human book. This human book is the result of the Gate of Reincarnation and the Roulette of Reincarnation. It contains The power of these two treasures is integrated with the underworld, so with the support of this book, the power of the nine hundred and ninety-nine black dragons is endless, and even you. Destroy the black dragons transformed by these black chains, and they will be reborn with the help of the human book."

"At the same time, the defense of this Renshu is also extremely terrifying. I once attacked Renshu with all my strength at any cost, but it didn't hurt him at all. On the contrary, I was severely injured by the nine hundred and ninety-nine black dragons, so I needed to recuperate. It took 30,000 years to fully recover!”

"So, it is really difficult, difficult, difficult to break this seal!"
