At this time, in Tianmu City, the peak of Yuanci Wuji Mountain.

Mu Lao Ghost and Han Mofeng looked at the battlefield from afar, one frowned, and the other looked indifferent.

"Brother Han, aren't you in a hurry at all?" After being silent for a long time, the old ghost finally couldn't help but speak.

"The Demon Sect's army is pressing, it's useless for me to be anxious. Han Mofeng shrugged.

"Alas, in the previous attack, the Demon Sect didn't know enough about our Tianmu City, so we were able to rely on the power of the combined battle formation and formation to temporarily repel them. But this time, the Demon Sect was obviously bound to win, not only did it give the holy weapon, but the number of Spirit Venerable-level monks nearly doubled. ”

"With the Golden Armor Seniors and Elder Ouyang both suppressed, the victory or defeat between the Spirit Venerable Cultivators can almost determine the survival of Heavenly Curtain City. ”

Han Mofeng patted the old ghost Mu on the shoulder and comforted, "Don't worry, isn't it that the power of the big array hasn't been used yet." ”

"The Demon Sect's Demon Source Cannon hasn't been used yet. The old ghost panicked in his heart.

"We still have Naga as a hole card. Han Mofeng was very calm.

"I saw the Yin Yang Coffin in the camp of the Demon Sect, which contained the demon corpse refined from the corpse of an ancient giant, which could compete with Naga. The old ghost was even more panicked.

"Uh...... Then we also have the half-holy puppet refined by the Nine Dark Snow Wings. Han Mofeng was almost speechless.

"There are two ancient giants in the Yin Yang coffin, a man and a woman. Old Ghost Mu looked at Han Mofeng with burning eyes, as if he was expecting him to expose some more hole cards of Tianmu City that he didn't know.

Han Mofeng scratched the corner of his forehead and didn't answer for a long time.

"Do we have any other hole cards?"

"This ...... That one...... I haven't made a move yet, Elder Mu, do you think I'm a hidden hole card?"

"I suddenly wanted to close the big array and surrender to the Demon Sect. ”

"Don't, Elder Mu, you have to believe me, although I don't shoot often, my strength is still very terrifying, the Demon Sect is a half-saint or something, I can pick ten or more. Han Mofeng patted his chest and promised.

Elder Mu supported his forehead. Big brother, you are a spiritual venerable monk, and you still want to pick ten half-saint monks, do you dream?

"Knock-" The gong sounded, and the sound rolled.

Elder Mu and Han Mofeng looked in the direction where the gong came from at the same time, but next to the nearly 100-zhang huge yin-yang coffin, a strong man with a naked upper body, holding a giant hammer, sounded a purple gong the size of a zhang.

The gong sounded, and the sound waves passed through, and the five hundred boys, boys, and girls standing next to the yin and yang coffins all exploded into a cloud of blood mist. Those thick blood mist were quickly absorbed by the strange runes engraved on the Yin Yang coffin.

"The people of the Demon Sect deserve to die. Han Mofeng and Mu Lao Ghost witnessed this scene, and their faces were extremely gloomy.

The blood mist poured into the Yin-Yang coffin, and with a bang, the lid of the Yin-Yang coffin bounced up, and two huge figures flew out like phantoms, rising into the air and standing in the air.

"Jingle Bell, Jingle Bell—" A Lingzun monk appeared above the head of the Yin and Yang Twin Demons, holding a copper bell, and with a slight shake, the Yin and Yang Twin Demons froze.

"Yin and Yang Twin Demons, if you break that big array, everyone in the city will become your blood food. The Demon Sect Spirit Venerable shouted.

The Yin and Yang Twin Demons stared, their fangs were exposed, and their huge bodies of nearly a hundred zhang moved as fast as lightning, and all the people who stood in their way were torn apart by their claws.

"Let Naga and the Nine Stygian Snow Cocktails enter. Elder Mu shouted, and several Spirit Venerable Cultivators flew out, each pinching out the seal and striking out a pillar of light. The pillar of light submerged into the condensed light curtain of the great protective array, leaving to manifest a huge whirlpool, and the seven Naga and the Nine Dark Snow Leeches that had been refined into puppets snaked out, swimming along the sky, and after a while, they were fiercely fighting with the Yin and Yang Twin Demons.

The battle of the four semi-saint-level existences directly cleared the sky into a vacuum area of thousands of miles, and no one dared to approach it.

In the depths of the Demon Sect's army, more than a dozen black-robed people gathered together, and the leader of them saw the Yin and Yang Twin Demons fighting together with the Seven Naga and the Nine Dark Snow Puppets, and gave a deep order.

"Prepare the Demon Source Cannon. ”

The black-robed people around him immediately scattered, separated by hundreds of miles from each other, and practiced in a line. With a wave of their hands, a huge cannon as high as a thousand feet appeared on the ground, and the surface of the dark barrel was engraved with unknown runes.

This Demon Source Cannon is ten times larger than the main cannon of the Xuanjing Cannon. More than a dozen black-robed people quickly took out pitch-black spars and inlaid them in the energy core of the Demon Source Cannon.

"Elder Iwan, the Demon Source Cannon has been prepared. ”

"Concentrate a little and open fire. ”

"Yes. ”

At the top of Yuanci Wuji Mountain, Elder Mu and Han Mofeng took action as soon as those demon source cannons appeared.

The two of them flew down the top of the mountain in an instant, rushed into the palace on the mountainside, each took out a token, and quickly played the magic trick to sacrifice the token.

The Yuan Magnetic Five Extreme Array was immediately triggered, and the hundreds of stone pillars standing around the mountain peak burst out with earth-shattering spiritual light and rushed into the sky.

"Boom-" The sound of the cannon sounded in the sky, and the Demon Source Cannon shot out more than a dozen pillars of black light hundreds of zhang thick, blasting towards the city protection array. Wherever the pillar of light passed, the monks who didn't have time to dodge were all annihilated and disappeared. Around the pillar of light, the space was wildly distorted, rippling with undulating ripples.

The stimulation of the Demon Source Cannon also attracted the attention of many Spirit Venerable Monks and Demi-Saints in the sky. That huge jet-black beam, even if they were touched, it would be a dead end. The Spirit Venerable Cultivators on the side of Skylight City stared at those beams of light nervously, as if they wanted to personally determine whether the Great Protective Array of Skylight City could block them all.

"It's coming. Beishan's gaze turned to the Tianmu City, and the light above the Yuanci Wuji Mountain converged, forming a huge pentagram pattern, and the iron cyan aura in the middle of the pentagram surged, and the next moment it turned into a pillar of light with a thickness of thousands of zhang and shot out.

"Metamagnetic Aurora. Iron Lion's face was overjoyed.

"Boom—"

The Yuan Magnetic Aurora and the Demon Source Cannon Light collided together, exploding with each other, and the annular shock wave bloomed, crushing everything within a radius of thousands of miles.

The Spiritual Venerable Cultivators in the sky also retreated, not daring to resist the shock wave in the slightest. Behind the Demon Sect's army, the black-robed man looked at this scene with a blank face.

"Keep firing. He coldly ordered.

"Elder Iwan, the Demon Source Crystals we brought out this time have all been consumed. A black-robed man flew forward and cautiously replied.

Elder Iwana frowned slightly, and then stretched out.

"Put away the Demon Source Cannon and retreat, your mission is accomplished. ”

"Yes, thank you, Elder Iwanyana. The black-robed people were overjoyed, and after hurriedly bowing and saluting, they flew down. Soon, more than a dozen black-robed people put away the Demon Source Cannon and retreated towards the rear of the army.

Elder Iwancheng looked up at the sky, the battle group of the half-saint monks was still inseparable, the Yin and Yang Twin Demons and the Seven Naga and the Nine Shadows Snow Cockroach could barely fight each other, the only thing that made him feel relieved was that the Spirit Venerable Cultivators of the Demon Sect had completely suppressed the Spirit Venerable Monks of Tianmu City, and it was only a matter of time before they completely annihilated the other party.

"We can't continue to drag it out, we have to end the battle quickly and occupy Skylight City, otherwise those old guys from the Anti-Demon Alliance should send someone over." ”

Yan Cheng stomped under his feet and turned into an astonishing rainbow of light and rushed into the battlefield, but in an instant, he came to the front of the protective light curtain of the Yuanci Five Extreme Array, and smashed it down with a fierce punch.

Seeing his actions, a thought rose in the hearts of the monks who noticed him. Is he crazy? He actually wanted to rely on the strength of his physical body to break the defensive light curtain of the eighth-order formation.

But the next moment, everyone's eyelids jumped violently at his punch. With that punch, it seemed that even the entire heaven and earth were shaken, the space was shattering rapidly, and cracks spread along the defensive light curtain of the Yuan Magnetic Five Extreme Array, like a pitch-black spider web.

"How is that possible?" Beishan and Iron Lion were stunned and shocked.

The force of the shock shattered the black robe on Elder Iwana Clan, revealing his true face in front of everyone's eyes. Silver hair, black eyes, purple armor, a pair of sharp teeth protruding between the lips, and a majestic terrifying aura was released.

"Elder Iwanari. "The Demon Sect monks were all pleasantly surprised.

"Purple Armor Heavenly Corpse. On the side of Heavenly Curtain City, all the Demi-Saint Elders exclaimed.

"Hey, it can withstand a punch from this seat without breaking, and it doesn't look like an ordinary eighth-order formation. Elder Iwatsuya looked at the defensive light curtain in front of him with some surprise, and those cracks began to repair quickly under the power of the formation.

"Well, then, let's use the Hallows, I don't have time to spend it here. Talking to himself, Elder Iwana raised his hand and held it weakly, and a purple axe appeared in his hand, holding it tightly and the light bloomed.

"Broken. With a roar, the purple axe slashed down.

"The Eye of the Evil Emperor, forbidden. ”

"Yuan Magnetic Aurora, kill. ”

Two majestic voices rang out one after the other, and a gray beam of light pierced through the void at lightning speed, enveloping Elder Iwayan's body, causing his movements to freeze instantly. It was only a brief moment, but it was enough to prevent him from making any defenses or dodges.

The Yuan Magnetic Aurora that followed was bombarded Elder Iwayan's body head-on, sending it directly into the void, leaving behind a pitch-black spatial black hole.

"It worked. Elder Mu said in surprise.

Han Mofeng didn't have any response, he escaped the light to the extreme, and in a few flashes, he crossed half of the Sky Curtain City, rushed out of the defensive light curtain of the city protection array, and appeared in front of the spatial black hole.

The strength of the Purple Armor Heavenly Corpse was definitely beyond everyone's imagination, even if he was unsuspectingly hit by the Yuan Magnetic Aurora, he would definitely not be able to cause much damage to him. To kill the Purple Armor Heavenly Corpse with this blow is even more wishful thinking.

His flying hands were sealed, and the power of the blood in his body was stimulated, the black wings opened behind him, the silver scales grew out one by one, and two dragon horns drilled out of his forehead, his eyes were blue and gold, and a vertical pupil in the center of his eyebrows was closed.
