Watching the two of them slowly approach towards the nine formation base pillars, Gu Yan outside the formation was also nervous, judging from the speed at which the two of them approached and the marks they left on the hard rock ground, Gu Yan knew what a huge pressure the ghost withered Tuoba Hong was under at this time.

According to the record of the Lingzun Formation, if you want to connect the main body of the formation with the nine foundation pillars of the formation, you must rely on a more powerful force to wrap the base pillar and prevent it from coming into contact with the formation.

For Ghost Ku and Tuoba Hong, the most powerful energy is also the most direct is their true element. I saw Ghost Ku walking towards the three red Yanyang jade pillars, while Tuoba Hong was standing in the center of the nine formation base pillars.

Immediately, Tuoba Hong and Ghost Ku glanced at each other, only to see Oniku's body standing towards the ground, his feet sinking deep into the hard rock, and at the same time, his thick arms exuded a strong demonic aura.

Between the two palms, a black ball of energy continued to swallow demonic energy, gushing in all directions, the ghost withered and roared to the sky, and the energy black ball in the palm of his hand suddenly formed three dark black chains, locking the three black stone pillars in front of him.

As the black chains made out by the ghost wither shrouded the three formation base pillars, suddenly the entire Jiuyang Forbidden Yuan Array seemed to be stimulated by something, and the nine Yanyang Jade Base Pillars kept shaking, and the entire mountain range where the Sanfu City was located was shaking.

Gu Yan stabilized his body and squatted on the ground, he didn't want to go into the magma in the center of the earth to take a hot bath.

Streams of energy from the main body of the formation frantically got rid of these three black chains, but Tuoba Hong on the side would not let it get its wish.

The figure fell, and then Tuoba Hong condensed one hand into a fist, and hit it towards the sky above the formation, a huge palm print, and immediately scattered the red energy that the formation shot out.

This has not stopped, Tuoba Hong's hand shape changed again, looking at the hand-shaped Gu Yan, he knew what Tuoba Hong's move was, it was the Void Great Handprint used by the demon spirit that day. However, at this time, the power of the Void Great Handprint played by Tuoba Hong was a hundred times stronger than that of the demon spirit.

The huge palm print shrouded directly towards the nine formation base pillars, and the nine constantly shaking formation base pillars were suddenly forcibly suppressed. However, it could also be seen from the hideous expression on Tuoba Hong's face that although he suppressed the nine stone pillars, it was enough to choke.

However, at this time, the ghost withered seized this brief opportunity and immediately condensed the black chains, and the three Flame Sun Jade Base Pillars that had been locked before were instantly cut off from the center of the formation by a black energy light mask.

As the three formation pillars were completely locked, Tuoba Hong, who had endured this huge resistance, suddenly felt a lot more relaxed, laughed, and once again condensed a huge palm seal with his other hand, and sent several magic seals towards the remaining six stone pillars.

In this way, the nine Flame Sun Jade Formation Base Pillars were all locked, completely severing the connection with the formation center. Gu Yan, who was outside the formation, also smiled happily at this time, he could already clearly feel that the power of the Nine Yang Forbidden Yuan Array had weakened by more than half.

However, at this moment, Tuoba Hong and Oniku's faces suddenly changed drastically, especially Oniku, whose legs that had been trapped under the hard rock retreated uncontrollably, leaving a groove on the ground that was pressed out by the soles of their feet.

And Tuoba Hong was no better, his two hands kept making palm prints, but he turned his head with difficulty and looked at Gu Yan, "Lord, go quickly, the blocked desolate vein energy is rioting, and it has reached the verge of eruption, and I can't hold it for long!"

Looking at the ghosts and Tuoba Hong who were struggling to suppress the desolate qi, how could Gu Yan sacrifice them in exchange for his own survival, and stepped forward, Gu Yan also stepped into the Jiuyang Forbidden Yuan Array.

Suddenly, Gu Yan's body fell towards the ground, fortunately, the formation energy at this time had weakened by half, and the energy riot was not so concentrated, otherwise Gu Yan would not have been as simple as just falling.

Gu Yan struggled to stand up, and entered his true yuan towards the black energy shield held up by Ghost Ku and Tuoba Hong, looking at Gu Yan, "Lord, why are you here too?" A look of anxiety appeared on Tuoba Hong's face.

However, Gu Yan reluctantly squeezed out a smile, "I, Gu Yan, am not a person who will leave my brother, even if I die, my Gu Yan will be with my brother." As he spoke, Gu Yan took a step back, and his arm had been squeezed out of the slightest trace of blood by the huge pressure, dripping under the ground drop by drop.

Seeing that Gu Yan was actually injured, Tuoba Hong roared wildly, and slapped his two hands forward, and the black energy light mask suddenly became much more condensed.

However, Gu Yan was still too weak after all, and knelt on the ground helplessly, but at this moment, a familiar voice suddenly came from the sea of knowledge, "Little master, why are you so stupid, isn't there a lack of energy in the Void Tower!"

Listening to Xiao Bi's words, Gu Yan was stunned for a moment, yes, such a majestic energy is a super tonic for the Void Tower. I knocked it on my head, I didn't think of it just now.

Standing up again, the black void tower in his hand was urged by the ancient rock and suspended in the air.

"Sacrifice, you open a small opening and let the Void Tower absorb those majestic energies. Gu Yan said to Tuoba Hong.

Hearing Gu Yan's words, a smile appeared on Ghost Ku's face, and Tuoba Hong nodded, "Venerable Lord, I only opened a small opening. Soon, a crack appeared on the black energy cover, and streams of incomparably pure energy suddenly gushed out.

Gu Yan's heart flashed, and he saw a golden light flashing from the Void Tower, shining on the small black opening, and suddenly, all the energy gushing out of that small mouth was sucked into the Void Tower.

Such a huge amount of energy can be described as a great supplement for the Void Tower, Gu Yan opened all the thousands of spirit gathering formations arranged by the Spirit Venerable in the Void Tower, and suddenly those energy that was absorbed into it were directly condensed into spiritual liquid by one by one Gathering Yuan Formations, and floated in the Void Tower.

And Xiaobi is also the body of the tree flickering, frantically absorbing that energy, the color of the leaves gradually deepened at a speed visible to the naked eye, and at the same time, the body of the tree is also growing differently, and the Fire Spirit Holy Fruit is no exception.

The entire Void Tower's elixir, the desolate beasts, were all enjoying this energy feast, and at this time, Gu Yan found that the energy that was inhaled seemed to be a little insufficient.

"Sacrifice, open the opening a little wider, and I will let all this energy enter the Void Tower to form a barren stone vein. Gu Yan's heart sank, and once again all the spiritual energy that had been inhaled, part of it was directly injected into the barren stones buried in the Void Tower.

In the past, because of the lack of barren stones, Guyan only buried hundreds of thousands of barren stones in the Void Tower, and the improvement effect on the Heaven and Earth Vitality of the Void Tower was not obvious. Because according to Xiao Bi's understanding, if you want to form a barren stone vein in the Void Tower, at least millions of barren stones will need to be bred for a short time.

But now it is not needed, such a huge amount of energy was directly absorbed by Gu Yan by the formation under the barren stone, condensing into a new barren stone vein.

The mouth opened again, and more majestic energy gushed out, and gradually, the heaven and earth aura in the Void Tower was almost dense into mist, not to mention that most of it was used by the ancient rock to condense into barren stone veins.

At this time, the energy of the previous riot had become much calmer as it was frantically absorbed by the Void Tower, and at this time, Gu Yan began to slowly stop the Devouring of the Void Tower, he didn't want this super vein to be absorbed too much energy, causing irreparable losses.

At this time, Ghost Ku and Tuoba Hong finally breathed a sigh of relief, looked at the Void Tower, and secretly rejoiced in their hearts, if it weren't for this small tower this time, the consequences would be really unimaginable.

"Lord, are you alright?" Tuoba Hong held Gu Yan with one hand, Gu Yan only had some blood stains on his arm, but he was not too injured.

Gu Yan took the Void Tower into his body, and this time the Void Tower could be described as a full meal, such a huge amount of energy was enough to make the environment of the Void Tower change dramatically. Although it was a thrilling one, the harvest was enough to make people crazy.

However, at this moment, Gu Yan's body suddenly trembled wildly, and the blood in his body began to surge uncontrollably towards the injured arm, and that arm seemed to be attracted by something, towards the center of the nine Flame Sun Jade Pillars.

Gu Yan was lying on the ground, completely uncontrollably dragged by that arm, and the blood in his body seeped uncontrollably into the ground.

Looking at Gu Yan, whose faces were pale, Ghost Ku and Tuoba Hong were also shocked, and they didn't understand the situation at all.

"Lord, what's wrong with you?" Tuoba Hong held the trembling Gu Yan, and the ghost on the side found that there seemed to be something in the ground that was devouring Gu Yan's essence and blood.

At this time, Gu Yan's mind was dizzy, and he seemed to be suffering from this extremely large amount of energy, coupled with the loss of essence and blood, the whole person was completely unconscious.

"Brother Tuoba, there seems to be something in this underground that is devouring Gu Xiaozi's essence blood again, and it must be stopped immediately, otherwise Gu Xiaozi's essence blood will be swallowed up sooner or later. Saying that, Ghost Ku grabbed Gu Yan's arm where Gu Yan's blood was constantly flowing out with one hand, but he couldn't stop it at all.

And Tuoba Hong put down the ancient rock, got up and stood on the ground, and raised his fist to smash the ground, when under the ground, a stone crack suddenly cracked, and gradually, an inexplicable coercion overflowed, and then, a black stone platform suddenly rose, with a fierce fang-shaped Fang Tian painting halberd inserted on it!

Feeling that coercion, the faces of Tuoba Hong and Ghost Ku changed at the same time, as they found that it was this Fang Tian Painting Halberd that was devouring Gu Yan's essence blood. But fortunately, it seems that Gu Yan's arm is no longer bleeding at this time.

However, because nearly forty percent of the essence blood was devoured, Gu Yan's face was pale, and he was reluctantly helped up by Tuoba Hong, took out a small jade bottle from the storage ring, took out three red pills and threw them into his mouth, and only then did a trace of blood appear on his face.

What happened to Gu Yan on this trip can be described as inexplicable, and he didn't know anything at all, and he was almost sucked dry of his essence and blood, and lost his life. Gu Yan looked at the black stone platform in front of him that devoured his essence and blood with a depressed expression, and the thought in his heart that Zhenyuan wanted to swallow it.
