The thirty-six demon pillars gathered energy and used the altar as a forbidden array to suppress the killing, which was undoubtedly the method of building the Heaven Sealing Cloud Array.

Although it is also the Heaven Sealing Cloud Array, the Heaven Sealing Cloud Array in front of him is nothing compared to the incomparably huge Heaven Sealing Cloud Array in the Silver Palace.

In Chu Yuan's opinion, this formation can only be said to be a simplified version of the Heaven Sealing Cloud Array, and the energy that can be released may not reach one percent of the real formation.

But even so, once the Heaven Sealing Cloud Array was activated, even if it was just one percent of the energy, it would be enough to wipe out everything!

Bang! Bang!

Chu Yuan's mind was racing, and while thinking of ways to break the game, he was fighting, entangled, and mediated with the one hundred and twenty-eight ironclad warriors.

There is a huge difference between the 6th and 5th waves of ironclad warriors.

This wave of ironclad warriors are all sudden warriors, armed with swords, guns, swords, halberds, and heavy hammers, although the realm is still the Nine Heavens of the Law Spirit, but the lethality and combat power are extremely fierce.

Chu Yuan has the power to fight beyond the ranks, and in his heyday, he is completely able to fight with the martial artists of the first and second heavens, and even under the fifth wave of offensives, he can still move forward!

But at this time, under the tireless and crazy siege of the ironclad warriors, it also began to fall into disadvantage.

Rumble!!

The ironclad warriors flanked back and forth, besieging closely, and the three ironclad warriors with heavy hammers shot at the same time, and the heavy and domineering force smashed the flying sword on his chest, Chu Yuan only felt that he was hit by a huge force like a mountain, his chest snorted, a scarlet blood arrow spit out, and the whole person was blasted away more than ten meters away!

Fortunately, he was able to stabilize his body when he was blown away.

Damn it!

Chu Yuan wiped the blood from the corner of his mouth, his face was very solemn, and his gaze fell on the Sealing Heaven Lock Cloud Array again.

This wave of ironclad warriors, both in terms of combat power and cooperation with each other, has formed a tacit understanding, which is very difficult, although he is sure to bury them all, but it is bound to pay an extremely heavy price!

You know, once the sixth wave is over, there will be a seventh, eighth, and even ninth wave.....

And even if he showed the hole card of the dragon pattern and successfully passed the first level, he was bound to be scarred at that time, so he chose to enter the second level with the heart, and he was unable to deal with the more perverted trial!

Therefore, never use the dragon pattern unless absolutely necessary!

"We must find a way to open the Heaven Sealing Cloud Array!" Chu Yuan said firmly in his heart.

After experiencing a siege by ironclad warriors, Chu Yuan no longer chose to fight them head-on, but adopted the tactics of mediation and sneak attack to slowly wear down these ironclad warriors.

At the same time, while mediating, Chu Yuan was also trying to find a way to find the energy hub of the Heaven Sealing Cloud Array, which was the so-called Eye of the Array.

However, before the formation is opened, the energy hub is the energy hub, and it cannot be said that the energy hub is the eye of the formation, and the two cannot be generalized......

Generally speaking, all formations in the world have an energy hub that serves as the root of the activation formation.

The Heaven Sealing Cloud Array in this palace is a complete and intact formation, and the only possibility why the formation has stopped running is that it has not been opened.

Therefore, as long as you find the energy hub of the Heaven Sealing Cloud Array and open it, then you can kill all the ironclad warriors who are shrouded in the formation!

The energy hub is the core of the entire formation, and it is the most important part of the formation, so the energy hub is either protected by the formation itself and hidden within the formation, or hidden outside the formation for external protection.

It's just that nine of the ten formations in the world hide the energy hub within the formation.

Therefore, it is very likely that the energy hub of the Heaven Sealing Cloud Array is hidden in the formation.

But Chu Yuan felt that with the urine nature of the Aether Ancient Dragon God, he would never allow himself to find the energy hub so easily, otherwise this trial would be too unchallenging.

In fact, Chu Yuan had already probed, and the Ancient Dragon God was indeed as scheming as he imagined...... The energy hub is indeed not in the formation.

Well, now there is only one possibility left, and the energy hub is hidden somewhere in this palace.

It's just that this palace is extremely huge, and it is entangled by more than ninety ironclad warriors, and the impenetrable and dizzying offensive makes Chu Yuan unable to distract at all.

I don't know if it's because the consumption of spiritual energy is too serious and the strength has decreased, or because this wave of attacks has dragged on for too long, Chu Yuan feels that the offensive of these ironclad warriors is even more fierce and ferocious!

Bang bang bang!!

The furious exercises bloomed, and the sound of battle echoed in all directions.

In just half an hour, Chu Yuan had tens of thousands of collisions with those ironclad warriors!

As one ironclad warrior after another was killed strongly, Chu Yuan's body was also covered with dense scars and bloodstains.

And under the constant pressure on his body and the endless fighting, he felt more and more exhausted all over his body, and his spirit began to become tired.

But even so, he forcibly gritted his teeth and persevered to the end!

Chu Yuan knew very well in his heart that if these ironclad warriors were not all wiped out today, he would die!

As soon as he thought of this, Chu Yuan swallowed three Qi Replenishing Pills in one go, and after the aura in his body was restored to fullness, he rushed into the chaotic battlefield again to fight, like an incomparably ferocious beast frantically killing the enemy, the means were ruthless, and the momentum was like a rainbow, and the momentum was invincible, which made people feel frightened.

Chu Yuan fought with his sword, his sword momentum was like a rainbow, and his momentum was awe-inspiring.

In less than half an hour, that incomparably powerful and ruthless means directly destroyed more than sixty ironclad warriors.

At this time, the aura in his body fell into deficit again.

Without hesitation, Chu Yuan swallowed five Qi Replenishment Pills, quickly withdrew the red blood sword in his hand into the spatial ring, and then picked up a pitch-black heavy sword weighing a thousand catties on the ground.

Although the Red Blood Sword is light and light to use, and does not cause too much burden on one's wrist, in terms of its lethality, it is far from being comparable to weapons such as heavy swords and heavy hammers.

So when Chu Yuan picked up the heavy sword, although his body was no longer as agile as holding the red blood sword, his combat power had suddenly doubled!

Bang!

Chu Yuan, who was replaced with a heavy sword, was like a broken bamboo, like a god of war.

The heavy sword swept out, carrying a thousand powers, like a heavy hill bombarding the body. Although the heavy sword was sluggish, cumbersome, and not sharp enough to cut off the head of an ironclad warrior, the terrifying power smashed it into a pile of rotten iron, which was extremely terrifying and domineering!

Chu Yuan fought fiercely in the ironclad legion with a heavy sword, and every time the heavy sword was swung, two or three ironclad warriors directly turned into a pile of scrap iron.

Although this battle was thrilling, he was injured several times and almost hung by a thread, but it made him feel hearty, and for the first time, he felt that the heavy sword was so domineering!

Soon, under Chu Yuan's thunderous attack, almost all of the one hundred and twenty-eight ironclad warriors were wiped out, and just as he was about to kill the last ironclad warrior, Chu Yuan suddenly stopped the offensive.
