It's ......"

Shi Lan's eyes changed, and several of her commanders followed, and their faces were instantly solemn.

Fortunately, the school camp is not far from the city wall, but after half a cup of tea, the group rushed to the west city wall.

"Hiss......"

"My ......"

"Immeasurable... Tianzun ......"

After going up the city wall and seeing the scene outside the city, there was a commotion among the crowd.

Shi Lan took a few deep breaths before stabilizing her legs, which were a little weak.

The Xianwu Yin and Yang Great Array enveloped Xianwu City within a radius of ten miles, and at this moment, ten miles away was completely covered with all kinds of demon beasts, like a vast ocean, and there was no edge in sight.

Among them, the Dao figures flashed, obviously all of them were demon clans that had been transformed, and they swept away at a glance, no less than hundreds.

The demonic aura that soared into the sky, there was no need to feel it at all, the demon cloud that almost covered the sky was enough to make people despair.

The mountain gate of the Holy Martial Immortal Sect, which was originally located not far from Xianwu City, had also been completely engulfed by the beast tide, and there was no trace of the past atmosphere.

The Xianwu Yin and Yang Great Array was originally a composite large array that integrated many formations such as killing arrays, trapped formations, and defensive formations.

At this moment, the killing array has been fully activated, and ten miles outside Xianwu City, it has been covered with a layer of blood mud mixed with bones, and it is obvious that many demon beasts have died here.

The glowing array enveloped the entire city, and the demon clouds could not enter an inch, which made people feel a lot more at ease.

A breeze blew on his face, bringing a strong bloody gas, mixed with the fishy stench on the demon beast's body, which was disgusting.

"Roar—"

"Whoa—"

"Whew-"

The roar sounded again, and the beast tide was about to move, pouring out a group of nearly 100,000 beasts, rushing towards Xianwu City.

At the same time, nearly 10,000 demon birds swooped down from the sky, and the piercing sound of long chirps, mixed with the whistling sound of breaking through the sky, almost pierced people's eardrums!

Buzz –

The shining array suddenly skyrocketed, and countless yin and yang qi were pulled out of the void, condensing into a huge grinding disc with a snap of his fingers, almost covering one side of the heavens and the earth, and crushing down from the void!

The void was crushed by the Yin and Yang Mill Disk, and there was a loud roar.

The birds in the air bore the brunt of the blow, and they were crushed in an instant, and even the screams did not have time to be heard, and the gorgeous feathers were scattered in the sky, mixed with flesh and bones, and they were scattered one after another, outlining a magnificent blood-colored picture.

The terrifying terrifying qi machine, which pressed across the sky, pounced on the herd of beasts, and the momentum of advancing was stunned, with the intention of retreating.

However, the Yin and Yang grinding disc that had not been stained with the slightest blood wreckage did not give it a chance to regret it, and it was still castrated, and its body size became more and more inflated, like a star falling, and it was pressed down with a bang!

Rumble!

With a loud roar, the nearly 100,000 beasts, without a trace of resistance, were crushed into powder by the power of the formation in a snap of their fingers, and the residue of flesh and bones made the blood mud on the ground thicker, and the monstrous blood qi soared upward, condensing into a thin layer of blood mist in the air.

The beast tide returned to silence, and cheers rang out from the walls.

Shi Lan's eyes were full of surprise, the group of beasts that had just sprung up, many of them were in the Tiangang Realm, and even she saw a shape-shifting demon king, hiding in it, but under the Immortal Martial Yin and Yang Great Array, that demon king didn't even have the opportunity to manifest his body, so he was directly killed without any resistance.

In a flash of thought, Shi Lan's gaze moved to the blood mist condensed in the air, and she swallowed her saliva unconsciously, these blood qi, for her, were tantamount to a great supplement, which was of great benefit to her cultivation.

……

On the city wall, in a large tent that was temporarily erected, several town demon marshals sat opposite each other, different from the excitement of most people on the city wall, at this moment, their faces were full of solemnity.

"The energy to be consumed by the Immortal Martial Yin and Yang Great Array is too terrifying, just now a part of the killing array has been activated, and nearly a million spirit crystals have been burned in just a few breaths, with our current inventory, I'm afraid it won't last long."

"I just roughly calculated, if the big array is fully operational, the remaining spirit crystals in the army can last for twenty days at most."

"With so many forces and scattered warriors in the city, there must be some spirit crystals that can be taken out."

"Even if you add the spirit crystals of those martial artists together and last for a month, I'm afraid it's the limit."

"And there's always going to be some crystals to recover."

"I went out to rescue the women's camp before, and I lost too many spirit crystals, and even Ruiyu buried his bones here......"

"The demon clan is obviously planning to fight a war of attrition, these spirit crystals must be left to the demon emperor, if there is no immortal martial yin and yang array, in front of a demon emperor, we will not have the slightest power to fight back!"

"The killing array can't be used easily, you can only open part of the defensive formation, and you can ...... with the beast tide in short combat."

As soon as these words came out, the town demon marshals fell silent, this move is the only way, but there will definitely be a large number of casualties, and it is inevitable.

……

Shi Lan looked at the blood mist, licked the corners of her mouth, looked away a little unwillingly, and began to turn around and arrange for his men to set up camp.

Her black domain can envelop a radius of hundreds of zhang at most, far beyond the reach of those blood mist, and can only be watched with a blank eye.

The walls of Xianwu City are extremely wide, enough to accommodate millions of troops stationed, and Shi Lan's team is not conspicuous among them.

As he watched the Immortal Martial Yin and Yang Great Array easily crush a group of demon beasts with his own eyes, the atmosphere on the city wall was much more relaxed than before.

Two hours later, Shi Lan had just arranged his men and set up camp, and a demon army sent supplies outside the camp.

A large number of bows, crossbows and arrows were distributed to the hands of various demon soldiers and warriors, among which there were a large number of magic weapons, and even magic weapons.

When he received this batch of materials, Shi Lan was afraid that the Immortal Martial Yin and Yang Great Array would not be able to continue to operate like just now.

It is inevitable that they will engage in hand-to-hand combat.

……

"Holy Venerable, have you found the person you are looking for?"

Less than fifteen miles away from Xianwu City, in an inconspicuous corner of the beast tide, Lan Die'er stood respectfully behind the old man, and there were several big demons standing on the side, as if there was a barrier around it, isolating all the breath, and no one in Xianwu City found their existence.

"Perhaps......"

The old man looked at the city wall, his eyes were uncertain, and he opened his mouth slowly, and the dead air on his body was a little thicker.

"Then dare to ask the Holy Venerable, is there a way to break the formation?"

"Even in the heyday of this emperor, he didn't have this ability." The old man laughed at himself, his cultivation was far from being able to run rampant in the vast land of Shenzhou, if it weren't for the special situation, with his cultivation, I was afraid that there would be no chance to cross the border between the two clans.

"The Xianwu Yin and Yang Great Array is not broken, you want to take revenge, I'm afraid it's ......" Lan Die'er looked a little disappointed.

"It's not that hard to kill someone......"

The old man shook his head slightly, and said meaningfully: "The formation will not be open all the time......"
