"This blood refining array is to refine people's flesh and blood essence into the power of devouring gods, and the power of devouring gods can only be absorbed by those who cultivate the Heavenly Demon Skill, those martial artists on the Tianyuan Continent, even if the strong people of the Holy Emperor touch the power of devouring gods, the primordial gods will corrode and dissipate. And there is actually a complete blood refining array in this Death Demon Cave, who is this big array arranged here? Could it be the Saint Emperor powerhouse who has obtained the Heavenly Demon Holy Bead before?" Houston's mind was full of doubts.

"No, it is rumored that in ancient times, Mo Tianyun, the strongest man of the human race, collected a large number of corpses of strong people who died in battle and buried them here, and single-handedly shaped the Death Demon Cave, could it be that this blood refining array was arranged by Mo Tianyun back then? Impossible, as far as I know, the amount of power Mo Tianyun used was not the power of devouring gods at all, he had not cultivated the Heavenly Demon Skill at all, and the power of devouring gods was harmful to him. ”

Suddenly, Houston's expression was startled again, and he exclaimed, "There seems to be a hidden formation in this blood refining array. Houston began to observe carefully, his knowledge of these formations was all obtained from the Heavenly Demon Sacred Bead, if there was no Heavenly Demon Sacred Bead, even if he was a Saint Emperor powerhouse, it would be absolutely impossible for him to discover the formations hidden here.

After a moment, Houston took a deep breath, he had already recognized another formation hidden in the Blood Refining Array, this formation was also one of the many formations recorded by the Heavenly Demon Sacred Bead, called the Heavenly Demon Illusion Realm, which was a very clever illusion array.

A total of two formations recorded in the Heavenly Demon Bead appeared in the Death Demon Cave, which made it difficult for Houston to calm down.

At this moment, the Death Demon Cave shook violently again, and a large area of viscous red mist like blood rolled in from the front. Seeing this red mist, Houston's face suddenly changed, because this red mist was the power of devouring gods cultivated by the Heavenly Demon Skill, and this devouring power was many times more powerful than the power of devouring gods he cultivated.

Bump! Bump! Bump!

A dull sound came from that piece of red mist, and every time it sounded, the entire Death Demon Cave would emit a shock, only to see a blood-red skeleton a hundred meters high looming from the red mist, and the powerful god-devouring power continued to emanate from every bone of it, and from this blood-red skeleton, there was also a powerful momentum that made the heavens and the earth tremble.

"This is a blood slave, a powerful blood slave whose strength has surpassed the realm of the Holy Emperor!" Houston let out an exclamation, staring at the blood-red skeleton with a look of disbelief on his face. At this time, Houston's mind suddenly remembered all the information about the Blood Slave that he had obtained from the Heavenly Demon Bead.

Blood slaves, made up of countless corpses and bones transformed by the secret method of the Heavenly Demons, and then nourished by the blood and essence of yin to evil, the strength of the strength is closely related to the age of existence, as well as the bones required to form the blood slave, and the blood and essence breath of the yin to evil.

The blood slave is the slave of the Heavenly Demon Gong cultivator, and the Heavenly Demon Secret Book has the secret technique of enslaving the blood slave and will not betray, while the enslaved blood slave completely obeys the master's orders and can be used to assist in the battle, and can also be cultivated by absorbing the power of devouring the gods in the blood slave to strengthen their own strength.

The blood-red skeleton didn't attack Houston, and stood there in a daze, the two hollow eyes on the skull looking in the direction of Houston. It had sensed that there were outsiders here, but the outsiders had the same power as it, so it didn't attack Houston.

Houston's expression became extremely solemn, blood slaves will not be formed naturally, and now that such a powerful blood slave has appeared here, he doesn't have to think about it to know that this is deliberately done by someone, and this person also understands the various secret methods of the Heavenly Demon Skill.

However, what made him glad was that the blood slave would not attack the person who cultivated the Heavenly Demon Skill without the master's order, otherwise, in the face of such a powerful blood slave, even if he was a powerhouse in the Saint Emperor realm, he could only flee for his life, and he might not be able to escape.

Houston stared at the blood slave for a while, and then looked stunned, his face showed a touch of ecstasy, and he said in an excited tone: "This... This turned out to be a blood slave who did not recognize his master. Houston's eyes showed a burning color, and without the slightest hesitation, he immediately began to jerky the Blood Slave Seal, which was one of the several secret techniques he had obtained from the Heavenly Demon Sacred Bead, which was specially used to enslave the Blood Slave.

After a few breaths, the Houston Blood Slave Seal was finished, and with a wave of his hand, it shot out like lightning, accurately shooting at the center of the blood-colored skeleton's eyebrows and disappearing, and then waited for half a sound, but the Blood Slave did not change in the slightest, and the scene recorded in the Heavenly Demon Sacred Bead when enslaving the Blood Slave did not appear.

Seeing this scene, Houston showed a look of disappointment in his eyes, sighed lightly, and said: "My strength is too low, and I can't subdue the blood slave beyond the Saint Emperor realm, it seems that I can only accept it in the future, but I don't know who left such a powerful blood slave here and doesn't care." ”

Houston no longer pays attention to the blood slave, anyway, the blood slave will not attack the person who cultivates the Heavenly Demon Skill, and letting it stay there will not affect him.

Houston's gaze fell again on the phantom array hidden in the blood refining array, this phantom array was very powerful, with Houston's current ability, it could neither be arranged nor broken, but he knew the way to enter the formation.

After hesitating for a moment, Houston still entered the phantom array, and then shuttled through the phantom array according to the method he learned from the Heavenly Demon Sacred Bead.

Houston was extremely cautious, and every step he took had to be compared repeatedly, and he would only settle down after confirming that it was correct, and he knew that once he took a wrong step, he would be trapped in the phantom array, and it would be difficult to get out.

After walking hundreds of steps in a row, Houston finally succeeded in passing through the phantom array, and at this moment, he felt the space around him fluctuate slightly, and then his vision in front of him suddenly changed, and he had come to an underground cave in a daze.

It was a circular cave with a diameter of about thirty meters, and the entire cave was filled with a strong god-devouring power, and at the top of the cave was a two-meter-long square pool, which was filled with blood-red liquid and looked like blood.

When Houston's gaze fell on the pool filled with blood-red liquid, his expression suddenly became extremely excited, and his heart couldn't help beating violently, he recognized what it was at a glance, the energy materialized, it was a highly condensed god-devouring power that had turned into liquid.

"I understand, all the power of devouring the gods refined by the blood refining array arranged on it is actually stored here, this Death Demon Cave is simply a cultivation holy place tailored for those who cultivate Heavenly Demon Skill. Although it is not certain who the person who built this place is, the power of devouring the gods here is already so strong, and the blood slaves above have not held back, it is estimated that the strong man who built this place in the first place has either left or fallen. ”

"If I stay here to cultivate and absorb the power of devouring gods in this pool, then my strength will definitely increase by leaps and bounds. That's it, although I have become a Saint Emperor, I have only just embarked on the path of cultivation, these days, I will concentrate on cultivating here. Houston muttered to himself, then sat down cross-legged on the edge of the small pool and began to practice the Heavenly Demon Skill.

However, what Houston didn't know was that just when he was teleported to the underground cave by a spatial force through the Heavenly Demon Illusion Realm Formation, the Heavenly Demon Illusion Realm Formation burst open with a loud roar.

And around, there are several more powerful and mysterious formations that Houston has not discovered, these formations are connected to the Heavenly Demon Fantasy Realm, fate is connected, and the Heavenly Demon Fantasy Realm bursts, causing these formations to also protect themselves at the same time.

Boom! Boom! Boom! Boom!

These formations were very powerful, and with a series of violent roars, the powerful energy fluctuations brought by the self-protection of several formations caused the entire Death Demon Cave to vibrate violently.

The several formations that burst were all very powerful trapped formations, and what was trapped inside was actually the amount of origin power that had disappeared for countless years on the Tian Yuan Continent, and these amount of origin power had lost the binding of the formation, and suddenly spread out towards the surroundings. However, the entire Death Demon Cave was shrouded in formations and enchantments, and these Origin Power Powers could not leave the Death Demon Cave no matter what.

A powerful wave came from the void, and he saw that a very large array appeared in the void, if Jian Chen was here, he would definitely be able to recognize that this array was very similar to the ancient teleportation array he had seen in the Hell Gate Temple.

The only difference is that the formation that appears in the Death Demon Cave is much larger and more esoteric than the one seen in the Hell Gate Temple.

At this moment, a gust of wind suddenly blew in the Death Demon Cave, and I saw that the amount of origin power that had spread to the surrounding area was absorbed from all directions, and all of them entered this huge teleportation array.

The teleportation array suddenly emitted a strong white light, slowly rotating in the void, bringing an incomparably strong energy fluctuation, but it was covered by the formation and enchantment outside the Death Demon Cave, and people from the outside world couldn't feel it at all.

From the phantom array that Houston passed through when he entered the underground cavern, to the several trapped arrays that self-detonated behind him, and the huge teleportation array that appeared in the void, they were all interlocking and connected.

Once someone passes through the Heavenly Demon Realm and touches that spatial power and is transmitted into the underground cave, these formations behind will be activated by each other, and the self-explosion of the Heavenly Demon Illusion Realm formation will drive several other trapped formations that have sealed the amount of origin power, and then the amount of origin power will activate the huge teleportation array in the void, which has been designed early in the morning.
