In the underground at a depth of hundreds of miles, in the endless darkness, Shangguan sat cross-legged on the ground, exuding a faint and clear light on his body.

According to the cultivation method of "Eight Gate Dunjia", in the meridians of Shangguan Xiaoyao's whole body, the pure Yuan Power of the Nine Peaks of the King Realm flowed wantonly, and it was frantically concentrated towards the left brain position!

In the depths of Shangguan Xiaoyao's knowledge of the sea, bursts of sharp pain spread, and the painful Shangguan Xiaoyao was almost unconscious!

"It's really terrible!" Shangguan Xiaoyao gritted his teeth, and cold sweat rolled down his forehead.

This kind of pain does not seem to act on the body, but directly appears in the depths of Zhihai's soul, if it weren't for Shangguan Xiaoyao's firm will and extremely strong soul, I'm afraid that he would have already been in a coma in pain, and if he opened the "open door", he would naturally have failed!

"This 'open door', in the left brain position in the skull, once opened, not only the body will be strengthened, but the soul power will be able to advance by leaps and bounds, maybe my soul realm can rush to the third level of the emperor realm in one fell swoop!" Shangguan Xiaoyao endured the severe pain, controlled the yuan force in the meridians, and violently impacted the hidden blood in the left brain!

Under the impact of Shangguan Yaoyao's Yuan Force, the blood hole in the left brain, which represented the "open door", continued to bulge. Shangguan Xiaoyao faintly felt that his head seemed to be about to explode!

"It hurts, it hurts!" Shangguan Xiaoyao's forehead was bruised, his face was flushed, and his muscles were as tense as steel! With a violent roar on the left side of his head, Shangguan Xiaoyao's eyes darkened, and then he gasped. A feeling of extreme weakness was transmitted to all the limbs, and sweat instantly soaked all the clothes on the body!

Shangguan breathed for a long time, and ran the "Immortal Sutra" to adjust the yuan power and soul power in his body to the best state, and then began to clean up the mess on his body.

"No wonder the Cliffless Martial Saint wants to leave the 'Immortal Sutra' in the Void Realm-level Cliffless Secret Realm!" Shangguan said with a sigh: "If there is no 'Immortal Sutra' to repair the meridians and the sea of knowledge, and open the 'Open the Door' blood aperture, as long as you fail once, you will be wasted! I don't know how many elixirs you have to take to recover!"

The first attempt to open the "open door" failed, Shangguan Xiaoyao was not frustrated, if it was so simple and successful, then Shangguan Xiaoyao would have to wonder if this "Eight Doors Dunjia" was as strong as the legend!

Fortunately, there were more than one True Dragon Companion Grass and Nine Transformation Soul Restoration Grass in Shangguan Xiaoyao's hand! As for the other precious medicinal materials, there were countless of them in Shangguan Xiaoyao's space ring! The medicinal materials that Shangguan Xiaoyao had harvested in the Void Realm-level Cliffless Secret Realm at the beginning were a huge amount!

Recalling the process of opening the "open door" just now, Shangguan Xiaoyao frowned slightly.

According to the method recorded in the "Eight Gates Dunjia", he had previously condensed his Yuan Force and Soul Power to impact the blood aperture, and there was no mistake in the steps. Taking the True Dragon Companion Grass and the Nine Turns Soul Restoration Grass is exactly in accordance with the timing recorded in the "Eight Gate Dunjia", and the score is exactly right!

Shangguan Xiaoyao had even felt that the blood aperture in the left brain was about to open just now! But at the last moment before success, the blood aperture that was about to open suddenly burst open, yes, Shangguan Xiaoyao's previous efforts were all gone!

"It shouldn't be!" Shangguan looked puzzled.

Shangguan Xiaoyao's body has been strengthened by the "Immortal Sutra", and his physical strength is many times stronger than that of ordinary martial artists. Once you successfully open the blood aperture, the benefits obtained are much greater than that of ordinary martial artists! However, the body is strengthened, and the blood aperture is naturally stronger, and it is more difficult to open the blood aperture!

"My Yuan Force and Soul Power have been strengthened by the Immortal Sutra, compared to ordinary martial artists, the difficulty of opening the Blood Aperture is actually not too big......!

Thinking of this, Shangguan Xiaoyao was suddenly slightly stunned, and then laughed: "Understood, understood, it turned out to be because of this!"

When Shangguan Xiaoyao tried to open the "Open the Door" blood aperture just now, he used the soul power of the double peak of the Emperor Realm, so in the end, because that blood aperture could not withstand Shangguan Xiaoyao's overly strong soul power, it would suddenly burst open, instead of re-closing!

"Any King Realm martial artist, because of the restriction of knowing the sea, the highest soul power cultivation is the Great Perfection of the King Realm Soul, even the martial artists of the ancient era are no exception!" Shangguan Xiaoyao's eyes were blazing, and his face was confident: "And my soul, after experiencing the rebirth of the Divine Pattern Space, can break through this limit!"

"In other words, it's not that I can't meet the conditions for opening the blood aperture, but I used too much force, which led to the first failure!" Shangguan Xiaoyao smiled slightly, and removed the sweat-soaked clothes on his body, revealing perfect muscle lines, which looked extremely symmetrical and harmonious, and was full of endless power texture!

Sitting upright with his eyes closed again, Shangguan Xiaoyao shouted in his mouth: "The second time I opened the 'open door' blood aperture, give me success!"

As the words fell, Shangguan Xiaoyao's body was once again filled with clear light, and the pure yuan power and soul power in his body fused with each other, and the blood aperture representing the "opening the door" in the left brain position hit again! This time, Shangguan Xiaoyao perfectly controlled the strength of his soul power at the level of the Great Perfection of the King Realm, which was the highest strength that an ordinary King Realm martial artist could achieve!

"Whew, Whew......"

Accompanied by an incomparably violent pain, a non-existent trick in Shangguan Xiaoyao's left brain suddenly appeared. It's like having life, a drum, a swell, and then a moment of stability. Then it swells again, it stabilizes again, and so on!

When this acupoint first appeared, it was not much bigger than a sesame seed, and after swelling countless times, it gradually expanded as big as a broad bean!

"Eight doors Dunjia, the first door 'open the door', open it for me!" Shangguan Xiaoyao endured the severe pain, and shouted from the depths of his soul: "Stabilize me, open it!!"

It seemed that the shouting had an effect, and in Shangguan Yaoyao's left brain, the blood-colored acupoint vibrated slightly, and the surface flickered with thousands of blood lights, and finally stabilized completely!

Shangguan Xiaoyao opened his eyes suddenly, his face was full of joy: "The first gate of the Eight Gates Dunjia, 'open the door', it's done!"

As soon as the blood aperture was opened, the Yuan Force in Shangguan Xiaoyao's body and the soul power in the Sea of Consciousness suddenly concentrated wildly into the blood aperture, until the tea time passed, and the Yuan Force in Shangguan Xiaoyao's body was almost exhausted before filling this blood aperture, and the soul of the double peak of Shangguan Xiaoyao's Emperor Realm had already unknowingly broken through to the triple Emperor Realm in the process of opening the aperture just now!

Nearly one percent of the soul power of this Emperor Realm Triple was separated from the Sea of Knowledge, and combined with Yuan Li in an extremely mysterious way, gathering in the Open Door Blood Aperture, forming a unique Blood Aperture power!

The surface of the "Buzzing ......" blood aperture trembled slightly, and there was a faint golden luster in the blood light emitted, and then calmed down again.

Shangguan Xiaoyao grasped the palm of his hand, and suddenly found the strength of his body at this time! Under his hand, the space near the palm of his hand shook slightly, and he almost couldn't withstand the power of Shangguan Xiaoyao's hand! And countless subtle electric rays of blood and gold appeared on the surface of Shangguan Xiaoyao's skin, which looked extremely strong and mysterious!

It was also at this time that in the King's Realm-level Cliffless Secret Realm, countless two kinds of thunderbolts that were blood-colored and golden suddenly appeared in the entire sky! These two kinds of thunder and lightning were intertwined with each other, shining and resounding over the entire Cliffless Secret Realm, the clouds were rolling, and the wind and clouds were roaring!

In the secret realm, whether it was the ninefold peak geniuses of the King Realm of the major emperor-level forces, or the masters of the Imperial Realm that they brought in through various means, including Yin Tianqing, an elite disciple from the Tianyin Holy Land, everyone looked up at the sky at the same time, but until the thunder and lightning disappeared and the heavens and the earth returned to calm, they couldn't see anything!

And underground, Shangguan Xiaoyao, the initiator of this thundercloud storm, has already finished pranayama and sat upright on the ground again! Now that he has obtained the Qilin essence blood just now, he wants to attack the second gate of the Eight Gate Dunjia in one go, and close the door!

Hugh and Door Break are slightly different in that in terms of location, the door is opened in the left brain position, while the Hugh Gate is located in the right head, which is just opposite to each other. And from the analysis of the difficulty of opening, the second door 'closed door' is more difficult than the first door 'open door', and the difficulty lies in the main material it needs, the unicorn essence blood!

To open the blood aperture of the Closed Gate, the first condition is to refine the Qilin essence blood, otherwise there is no need to talk about it!

Looking at the Qilin essence blood exuding a faint coercion in his hand, Shangguan Xiaoyao groaned slightly, thought carefully about the refining method recorded in the "Eight Gate Dunjia", and then tilted his neck and swallowed the Qilin essence blood directly into his abdomen!

"Roar!"

After swallowing the essence blood of the unicorn, the roar of the unicorn suddenly came from Shangguan Xiaoyao's chest and abdomen! A two-foot high unicorn phantom completely enveloped Shangguan Xiaoyao's body, shook his head and tail, and roared incessantly! Shangguan Xiaoyao's face was as pale as fire, and the skin on his body seemed to be cooked, red and hot!

And in the open-door blood aperture that Shangguan Xiaoyao had just opened, it was formed by the combination of yuan power and soul power, and the power of those blood aperture that was shining with blood-colored electric rays and golden electric rays was surging out frantically at this time, firmly enveloping the qilin essence blood!

"Whew!" Shangguan Xiaoyao's complexion and skin slowly returned to normal, and then a heat wave erupted, burning the ground in front of him black!

"It's worthy of the Qilin essence blood, it almost burned me to death!" Shangguan Xiaoyao looked down at his chest, feeling that the power of the blood inside was slowly refining the Qilin essence blood, with a slight smile on his face, and then swallowed the other medicinal materials needed to open the second door "Hugh Gate" one by one.

After absorbing the medicinal power, the Yuan Force in Shangguan's meridians surged wildly again, and the soul power in the sea of consciousness couldn't help but rise.

"The second gate of the Eight Gates Dunjia, close the door, start to impact!"
