The Book of Heaven has always been Yi Chen's secret, and it was precisely because of the Book of Heaven that he embarked on this very special path of cultivation.

This is a very mysterious and powerful treasure, even if it is a small demonic beast, it comes from an ancient inheritance, and I don't know what it is, and now this resonance can be determined that it must also be a treasure in the ancient period.

However, when he saw that the Book of Heaven was about to fly out, he couldn't help but get nervous, if the secret of the Book of Heaven was exposed, it would be very unfavorable to him, so he must not let this kind of thing happen.

"Give me peace. Yi Chen heard such a voice in his heart, and then he began to mobilize his soul power to make this book of heaven completely quiet, but this seemed to be in vain, and the book of heaven was still slowly rising.

"What's going on with the Ancient Excalibur, this resonance, it seems to be a kind of resonance of the Great Dao, which makes me have a mysterious feeling. ”

The primeval divine sword was also the same as the Book of Heaven, the fluctuations and resonance released were very obvious, and when they saw this scene, they couldn't help but wonder.

"What should I do, at this time, the Book of Heaven is not suppressed. Fortunately, they haven't found out the reason for Yi Chen for the time being, and immediately he tried harder to suppress it, but Tianshu was like a naughty child, not bound by him.

"Tianshu is obedient, hurry up and listen to the master's words. The little monster was also very anxious, flying up and squatting on top of the heavenly book, trying to press it down, but all these actions were in vain.

"Tianshu, you are not obedient, I won't be friends with you in the future!" The little monster saw that this didn't work, and even though he started to try to sell cuteness, Tianshu still ignored it.

At the same time, the pattern of the demonic beast on the cover of the Book of Heaven flashed with blood-red light at this time, and a wave of energy flowed in the lines.

"The Book of Heaven is going to change, it seems that it is very likely that the soul power I released came into contact with the Ancient Divine Sword, so they have established a special connection with each other, and it seems that they can only recover their soul power. ”

Absolutely not let the Book of Heaven be exposed, this is Yi Chen's idea at this time, he gritted his teeth, and then without the slightest slackness, he immediately withdrew all the soul power he had released.

"Huh" This seemed to have played a role, and just when he withdrew his soul power, the light released by the Book of Heaven immediately converged, and he no longer trembled, and became calm, staying quietly in the storage ring.

And the Ancient Divine Sword that was inserted not far away seemed to no longer release any fluctuations at this time because of the convergence of the Book of Heaven, which made the Demon King very puzzled, and his sharp eyes looked at Yi Chen.

There is nothing too coincidental in this world, why is it that as soon as Yi Chen's soul power comes into contact with the Ancient Divine Sword, it releases very strange fluctuations, and when the energy is withdrawn, it has no movement, it seems that there is a secret on his body.

"Hum" But they didn't have time to think about it, because at this time, the primeval divine sword had already felt the danger, it was originally a spiritual thing, and at this time it began to tremble violently, directly shaking the demon king and all their energy away.

The Ancient Excalibur had already sensed the danger, and it struggled more often, although it was very deep, but at this time it was withdrawing little by little, and it could leave at any time.

"Don't want to go. The Demon King immediately made a move, releasing their soul power and probing over, but when their energy was about to touch the primeval divine sword, the divine sword immediately trembled fiercely, directly shattering all their energy.

"Huh" And this is just the beginning, the movement just now, as if it woke up something inside, at this time, waves of fluctuations spread, Snow seabed crack is also trembling slightly, as if something is about to awaken.

Many of the cultivators who were originally standing on top of the blood-colored palace to fight were unstable and fell down directly.

"Looks like something bad is going to happen. With his experience of countless trials of life and death, as well as his keen sense of danger, he made such a judgment at this time.

Sure enough, at this time, the blood-colored palace released a dazzling blood-colored light, and countless blood-colored lines emerged from the blood-colored palace, each of which was very terrifying, condensing the power of heaven and earth.

When those formation patterns appeared, the cultivators present all felt a breath of vicissitudes of life, as if something that had been dormant for many years had been awakened, making their hearts tremble.

At the same time, a terrifying demon aura permeated the surroundings, which was extremely terrifying.

"Roar!" At this moment, the flame seemed to have some kind of sense, and even though he was very anxious, he roared angrily, as if to remind Yi Chen of danger.

"Flame's induction is generally not wrong, so quickly dodge. He trusted Flame Yichen very much, glanced at the Ancient Divine Sword, and then his figure flashed and quickly rose together, coming to a place hundreds of meters high, watching from afar.

"This blood-colored palace has changed, hurry up and dodge. "The cultivators who were originally fighting fiercely knew the danger at this time, and they mobilized their soul power to avoid it at this time.

"I'll talk about it when I get the Excalibur. "The Demon King, they didn't plan to go so lightly, and quickly rushed towards the Ancient Divine Sword.

"Boom" and at this moment, a dull sound came out, the blood-colored palace, the frequency of trembling was even more severe, and a magic circle suddenly condensed around, four rays of light quickly rose to the sky, and an extremely cold aura spread.

The cold air came from the blood-colored palace, and the surrounding sea water was frozen into ice, and the demon king wanted to seize the divine sword, but at this time they had to give up and quickly rushed up to the heights.

"Roar" At this time, around the crack on the bottom of Snow, the demonic beasts that had been hidden here all let out a very uneasy roar at this time, and then a large group of demonic beasts flew away into the distance, and they all seemed to feel the danger.

Yi Chen took a closer look, and immediately found that among the demonic beasts that flew away quickly, there was actually a quasi-king-level demonic beast, and he was immediately stunned. What was there in that blood-colored palace, even the quasi-king-level demonic beasts were so frightened.

"That blood-colored palace is really unusual, something is sure to happen later. At the same time, when Yi Chen looked back at the blood-colored palace, his eyes narrowed slightly.

Everyone stopped the fierce battle and looked nervously at the blood-colored palace, the crack under the sea of Snow is a forbidden place for the demon clan, full of all kinds of unknowns and dangers.

"Boom" the blood-colored palace, at this time under the fierce trembling, immediately because of the old years of accumulated sand, all of them were shaken down at this time, and the whole picture of the ice and snow palace could be seen clearly.

On all the lines, there was blood-red energy flowing at this time, and a cold aura spread out in all directions.

The magic circle formed around "Xiu" was integrated into the lines of the blood-colored palace at this time, forming a powerful and powerful magic circle, and immediately a magic circle was formed, and the shield slowly spread out to the surroundings, isolating the sea water.

"Boom" in the middle of the blood-colored palace, at this time, a large piece of concave bottom, forming a pool ten meters deep, filled with various mysterious lines.

The blood-red energy image flowing in the blood-colored palace was the pool where it gathered, and all the energy was injected into it, forming a pool of blood! Driven by the formation, it was like a fountain surging, and the cold air spread around the blood pool.

"How can this be, cold blood, how can this scene be so similar to the legend. When they saw this scene, all the cultivators were stunned.

"There should be no mistake, that is the most sacred place of our demon clan, the Extreme Yin Blood Pool!" "Heavenly Fury They know the secrets of the demon clan very well, so when they saw this scene, they exclaimed at the same time.

The Extreme Yin Blood Pool, the most sacred and mysterious place of the legendary demon clan thousands of years ago, is rumored to contain the blood of ancient ancestors, and it is the place where the first generation of demon clans were bred back then.

For the Extreme Yin Blood Pool, all the cultivators have a pilgrimage mentality, but there are too few records about the Extreme Yin Blood Pool, so everyone doesn't know where the Extreme Yin Blood Pool is, even if the hidden forces mobilize their forces to find it, they haven't found it.

Of course, for the Extreme Yin Blood Pool, there will also be some graphic records in the confusion, the blood pool did not appear at the beginning, there was just a palace, and now after it is completely condensed, they will recognize it.

"So that's the Extreme Yin Blood Pool?" Yi Chen was no stranger to a name, because when he got the items left by the Heavenly Demon King, he was entrusted by the Heavenly Demon King to lead his corpse to the Extreme Yin Blood Pool.

Since he has been inherited by others, it is very normal to help him do some small things, so Yi Chen wanted to inquire about the blood pool of the Extreme Yin Blood Pool, but because of some personal matters, he did not take action for a long time.

Now that he finally saw the Extreme Yin Blood Pool, a lot of waves rose in his heart, and his eyes moved to stay on those bloods, and his heart trembled immediately.

In those bloods, he felt a very terrifying life fluctuation, which was a powerful breath of life, hundreds of times more powerful than the blood of the demon dragon he encountered in the land of slaying dragons at the beginning.

"Is that really the blood left by the first generation of demon clan powerhouses?" Yi Chen's eyes flashed with greed, the little blood in the place where the dragon was slaying at the beginning made him gain a lot, if he could taste the blood in the Extreme Yin Blood Pool, then he would definitely get even greater benefits.

"The legendary holy blood, as long as you get a little, it has great benefits, even if I don't take it now, standing far away, I feel that my blood seems to have a very special resonance with that holy blood, it seems that there is really nothing wrong, that is the blood of our demon ancestors, the purest demon clan holy blood!"

At this time, the faces of those demon clans all showed excitement, a pool full of holy blood made them very excited, and at the same time, the look of greed also flashed in their eyes, as strong as when they looked at the primeval divine sword.
