It can be seen that the other elders who guard the formation do not seem to want to complete this action easily, because once all those old guys are released, it means that the mission of the eight elders who guard the formation will end, and the mission of the entire Northern Dynasty will also come to an imperfect end, which is definitely a practice of destroying both sides.

Once they open this taboo, Beihuang City will be completely in name only, and the entire fifth restricted area of ​​Tongtian Road will become a real purgatory.

Several elders who were guarding the formation had even begun to picture the scene in their minds.

The vast plain battlefield and every corner of Beihuang City will be filled with the blood of monsters and the terrifying ancient evil spirits that constantly devour their blood essence and power to improve their own cultivation.

No one can predict what kind of situation will arise after unlocking this forbidden trump card.

Everyone gradually turned their eyes to the great elder in the light yellow robe in the middle. After all, it was he who summoned the other fellow disciples, and he was also the one who truly had the right to open this taboo.

Gazing at the void and seeing Xu Yang's arrogant demeanor, the great elder in the light yellow robe finally gritted his teeth and gave the final order.

"There is nothing to hesitate about. With the strength of that human warrior and the hundreds of thousands of monsters under his command, it is only a matter of time before they attack the city.

Even if we old guys were to be broken into pieces, we would still be unable to withstand the sharp edge of that young human. If we don't completely release the ancient evil spirit, what would be the point of our Northern Dynasty living for hundreds of thousands of years?

Now that our duty is to guard the Fifth Forbidden Zone, no matter how big the mess is, as long as we can stop the invasion of this group of people and guard the peace of the top of Kunlun, the Supreme God’s consciousness should personally deal with all the mess left on the battlefield.

That is not something we need to worry about. Moreover, once we do this, at least the most powerful and advantageous forces in the entire Beihuang City can be preserved.

If we continue to fight these terrifying invaders, no one will be able to survive the sword of that guy named Xu Yang."

The great elder did have some self-awareness, but it was precisely because of his fear of Xu Yang's strength that this old man made the most wrong decision.

As the saying goes, "both sides will perish together," is this really an easy situation to face?

The Great Elder did not have time to think more, and finally gave the order to lift the taboo. In an instant, the eight elders who were guarding the formation stood proudly on the top of the hundred-foot city wall at the same time.

Each two people were about one hundred meters apart, covering a horizontal range of nearly a thousand meters. Colors condensed outside each person's body.

The completely different giant energy protective halo is three meters thick and is used to block the entry of external forces.

To ensure the perfect implementation of the entire process of the eight people removing the taboo seal.

When this shocking scene appeared, even Long Kun, who had already climbed to the side of the city wall, could not help but reveal a shocked expression, and immediately started a new round of spiritual communication with Xu Yang.

"Boss, it seems to me that these old guys suddenly appeared here to do something."

Little did he know that Xu Yang, who had just completely shattered the red mark on the void battlefield, also shook his head helplessly.

"I don't know what they are going to do. They will just fight back if they are attacked. I want to see what tricks they can come up with at this desperate moment."

Xu Yang was still as steady as ever. After all, for him, he had enough strength and did not need to be afraid of any fancy resistance.

In Xu Yang's opinion, although the Northern Dynasty was a famous force in the main continent hundreds of thousands of years ago, the times have changed. They are now incomplete and more like a spiritual symbol and a relic of civilization heritage, and are no longer as prosperous as they once were.

What's more, no matter how powerful their foundation is, the elite army of hundreds of thousands of monsters led by Xu Yang himself will not refuse anyone.

Finally, an extremely powerful formation totem was fused above the heads of each of the eight people. The partial totem imprint corresponding to each person was gathered together from various strange energy inscriptions.

The eight formations began to use the void as a blueprint and began to merge into one place in the middle, until the inscription layer of the entire forbidden formation was completely formed.

Xu Yang stared at the huge totem mark calmly, and he probably guessed something about it in his mind.

“I see. Most of these inscriptions and marks are used to seal some terrifying ancient monsters. It seems that there are indeed some terrifying creatures sealed inside the Northern Emperor City.

But they made it so mysterious that I became a little excited. I really want to see what these so-called ancient evil creatures that eat people without leaving any bones look like. "

Finally, when all the energy of the huge magic totem was gathered, it released a terrifying beam of light that reached the sky and the earth. The shocking aura covered every corner of the surrounding battlefield. All the monster legions seemed to have a sense of fear from the bottom of their hearts because of the arrival of this aura.

Until this halo connected to a mysterious energy between heaven and earth, all the black demonic energy was completely revived at this moment. However, the source of the flow of these demonic energy was not the area in the main battlefield, but in all directions of the deepest part of the North Imperial City behind the hundred-foot city wall.

More and more black demonic energy was released along with the terrifying roars of beasts.

"Oh my god, boss, look at what those black shadows are."

Jiuer and Xiaoxiang had followed Long Kun's vanguard troops to the top of the 100-foot city wall at some point, and immediately passed on the news to Xu Yang.

As expected, Xu Yang stood proudly in the air with a sword in his hand. Through the scene below the Beihuang City thousands of miles away, he finally got a first look at those ferocious creatures wrapped in the completely released black demonic energy.

“According to my judgment, these should all be the vicious monsters suppressed by the Kunlun Divine Dynasty hundreds of thousands of years ago. However, they have long lost their original bodies, leaving only their demonic souls full of demonic energy. However, they can also easily harvest the souls of any living being.

These are the strongest cards that the Northern Dynasty can play."

Xu Yang nodded slightly, having already determined the other party's true trump card this time. He felt much more at peace in his heart. He was not afraid that you would release any amazing means, but he was afraid that you would keep wasting time here and making confusion. Now that all the mysteries have been solved, there is nothing to hesitate about.
