Chapter 2314 The Terrifying Seal of the Underworld!

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 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 take a look at 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 mysterious and mysterious. It can be said that it is a power that is almost impossible to perceive and control, but cannot be eradicated. 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 his 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, and he can't 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 Emperor'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 the human book, the two powerful forces in his body seemed to be awakened by the breath of the human book. Then, a series of extremely terrifying breaths also surged out from Chu Xun, turning into two rays of light, one black and one blue, and directly rushed up from Chu Xun!

However, at this moment, the glass bodhi tree in Chu Xun's body also shone brightly, and stirred up a series of glass treasure lights, which merged into the black light, and at the same time, the blue light also separated a part of it to suppress the black light.

Boom!

The next moment, the black light was completely suppressed, leaving only the blue light rushing out of Chu Xun's body, turning into the shadow of the chaos bell, trembling violently, and bursts of earth-shaking bell sounds came from it, and even stirred up a series of blue sound waves sweeping in all directions.

As the blue sound waves swept, the human book connected by countless black chains also shone brightly, as if it was touched by the power of the chaos bell.

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

"Damn it!"

Seeing that the Yin Realm Seal had already launched a counterattack before he and others took action, Chu Xun's face suddenly changed.

But at this moment, the Black Mountain Old Demon suddenly took action, and then the entire Black Mountain City suddenly accelerated and hit the black dragons hard, knocking them back directly, turning them into black chains again, and shackled on 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 the Three Corpses Realm, but such a terrifying black dragon was easily knocked back by the Black Mountain City, and the Black Mountain City was not damaged at all. It is conceivable how terrifying the Black Mountain Old Demon, a super old demon who has practiced in the Yin and Yang Realm 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 little scared.

If the Black Mountain Old Demon hadn't wanted to spare their lives from the beginning, and their Zhoutian Xingdou Great Array just restrained the Black Mountain Old Demon, making it impossible for it to hit them easily, I'm afraid they would have suffered a great loss at the hands of the Black Mountain Old Demon, or even died at the hands of this guy!

"See? This is the power of the seal!"

Looking at the frightened and terrified looks of Chu Xun and the others, the Black Mountain Old Demon took a deep breath and said, "Once the power of the seal is fully activated, the 999 souls on the seal will turn into 999 black dragons, and each black dragon has the same power as the black dragons just now!"

"Not only that, the power of these black dragons can even be combined to exert even more terrible destructive power. Facing such power, even this seat dare not underestimate it. Even if all the black chains are deployed together, even if this seat goes all out, it may not be able to hold on for long!"

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

At this point, the Black Mountain Old Demon paused slightly, then pointed at the book, Said: "The most difficult thing to deal with is this book of man. This book of man is transformed from the Gate of Reincarnation and the Wheel of Reincarnation. It contains the power of these two treasures, and the power of these two treasures is integrated with the underworld. Therefore, under the support of the power of this book of man, the power of the 999 black dragons is endless, and even if you destroy the black dragons transformed by these black chains, they will be reborn with the help of the power of the book of man."

"At the same time, the defense of this book of man is also extremely terrible. I once attacked the book of man with all my strength at all costs, but it didn't hurt it at all. Instead, I was severely injured by the 999 black dragons. It took me 30,000 years to recover completely!"

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