The moment the Red Moon Demon King launched the attack order, the demon army suddenly became active and boiling like a boiling ocean, and this sky-high evil aura also woke up the boulder fortress, and this sleeping giant beast began to wake up and greet the enemy with a furious attitude.

Mu Yun commanded: "The defense state is on!"

On the surface of the boulder fortress, a large number of golden spells suddenly appeared, and the delayed spells arranged on the surface of the fortress were punished one by one, and a shocking scene appeared, the boulder fortress was coated with a layer of metallic luster from the beginning to the end, and the entire fortress seemed to have turned into a steel body, completely made of black iron.

"I didn't expect Black to do that. Nalan Tian showed a slightly stunned expression: "It's really worthy of Mu Yun!"

When Mu Yun arranged the spell defense offensive, he not only arranged a large number of traps to resist the enemy, but also arranged a large number of defensive traps on the surface of the boulder fortress, which is a very simple gold spell "Steel Rock Technique", whose effect can temporarily transform the rock into metal, with the hardness and toughness of the metal, so that the defense of the boulder fortress is greatly increased.

This would have been a common spell.

Mu Yun changed it to a delay-type trigger spell with a slight modification, and almost all warlocks who are proficient in the gold and earth system can quickly master it.

Mu Yun continued to command: "Activate the enchantment! Prepare to defend against the enemy!"

There is an underground magic field in the megalith fortress, more than 10,000 warlocks are sitting on the magic circle, when the sound of neat spells bursts out, each note overlaps tens of thousands of times, all are full of amazing power, the earth and the sky seem to be awakened, the energy between heaven and earth has gathered, and the boulder fortress is surrounded in all directions, and it is suddenly shrouded by layers of spell enchantments.

The Boulder Fortress is very strong, but the real defense is not the fortress itself, but more importantly, it comes from the spell enchantment, more than 10,000 warlocks work together to maintain the enchantment, and its strength is unimaginable, enough to block the demon army from the outside for a certain period of time.

As the demon legion surged forward, a black wave suddenly rolled up, and tens of thousands of ghosts rushed towards the boulder fortress.

These non-physical bodies purely use spiritual souls as energy carriers, and can only attack with the energy of attribute restraint, the speed of the ghosts is very fast, and in the blink of an eye, the entire sky is spread, and countless spirit bodies are connected to each other, and in front of the demon army, they form several huge black barriers.

The Akatsuki Demon King devours the demons.

The Akatsuki Demon King can have all the abilities of the Demon for a certain period of time, but the Demon King has a more powerful power of domination than the Demon Demon, so he can control the undead army at will, and when countless spirits form a barrier, the Demon King suddenly launches an attack.

"Screaming in pain!"

The barrier composed of hundreds of thousands of ghosts suddenly appeared as if there was a fluctuation that could not be captured by the naked ear, and a strong energy fluctuation hit the boulder fortress, ignoring any physical or ability defense, and the powerful spiritual power pierced into the brain, and everyone felt the pain of mental tearing, and the warlocks who were originally chanting the spell to maintain the enchantment were completely interrupted in front of the darkness at the moment of attack.

The spell enchantment that was about to take shape was directly dissolved.

Mu Yun showed a solemn expression.

The demon king used the undead of the ghost clan to release mental interference to interrupt the spell of the human warlock, when the goal was achieved, more than a thousand giant giant corpses, leading hundreds of thousands of undead armies like a rapid stream of water, drilled out of the gap in the ghost barrier, hundreds of thousands of monsters moved at the same time, the earth shook violently, countless gray smoke drifted into the air, the undead in the process of sprinting, hit his head on the trap, triggering the trap into countless mushu vines, when successfully entangled with the undead fire demon, the surrounding fire spells will explode, and the undead will be blown to pieces in an instant。

The Demon Legion continued to rush to the peak without fear.

The Akatsuki Demon King flew high, unleashing powerful energy from the blood-red Akatsuki Pupil, bursting out with a powerful beam of light that shrouded the earth, and when swept over the ground, thousands of traps were directly eliminated. The demon army was immediately relieved by the blockage, and began to continue to attack, the ghost barrier has always been in front, and the condensed power in it is like an indestructible shield, which can not only release spiritual attacks to interfere with spell casting, but also form a similar energy barrier to resist attacks from the front.

Whether it's a guided bomb or another weapon attack, it's all blocked by the Ghost Shield.

Use the physical characteristics of the ghost as a defensive shield?

Mu Yun's eyes flashed with a hint of strangeness, although the Red Moon Demon King should not be underestimated, but don't underestimate humans, Mu Yun ordered the warlocks to activate the delay type spell, and the ghost shield was advancing, and suddenly the ground in front of him cracked, and a large area of liquid emitting a pungent smell spurted into the air, forming a large area of mist.

The demon said: "Is it a trick?"

The Demon King said calmly, "No, the mana fuel generated by the water spell!"

"Heavenly Fire Technique!"

Celestial sorcerer Duan Tiangang waved his hand in the air, the sky was suddenly lit up, dozens of dazzling flowing fires roared, and they continued to bombard, when the flames fell on the dense fog with great concentration, the surging flames suddenly gushed out, like a terrifying monstrous wave, covering everything in an instant, and the flames that sparked were five or six hundred meters high, covering an area of thirty or forty square kilometers, almost completely enveloping the thousands of troops of the demon army in the surging flames.

Thousands of spell fuels.

One breath was ignited.

The power of the level 5 spell Heavenly Fire Technique blessed it, and the terrifying destructive power was already terrifying in an instant, as unstoppable as a monstrous flood, and the undead shield was shrouded in flames with countless undead, and it disappeared in a large range or in the end, and the strong shock wave generated by the explosion blew part of the flames into the fortress, making the fortress defenders feel in a hurry for a while.

The ghost could not withstand the flames for long, so after resisting for a while, it began to show signs of fading and melting, and finally had to retreat.

At this time, the demon army fell into the comprehensive defense range of the boulder fortress, the fortress up and down, inside and out, hundreds of stone throwing machines, at the same time sounded sound, hundreds of special spar bombs, each with a diameter of two or three zhang, from the black smoke and flames of the battlefield to draw a parabola, fell to the rear of the demon army, each giant spar bomb in the process of throwing into more than a dozen pieces, like a fairy scattered flowers fell into dense, like countless ants in the camp, blooming flowers.

Heavy Crossbow Activation!

Bow and arrow volley.

The soldiers defending the city here are all elite warriors, regardless of accuracy, there is no problem with an arrow shooting six or eight hundred meters away, and the dense rain of arrows blesses the true qi, shooting out like flying locusts, and sprinkling it continuously towards the demon army.

In the face of the strong resistance of the human race, the Red Moon Demon not only did not flinch, but launched a more ferocious impact.

The Demon Brake held the knife in both hands, condensed for more than ten seconds, and suddenly set off a black storm, turning into hundreds of thousands of black wind blades that were extremely sharp, and they were able to cut the flames into countless pieces, some of which fell on the fortress, and each attack was like a lightning strike causing a violent roar, causing many cracks to appear on the surface of the fortress.

The flames quickly waned.

The demon army continued in the direction of the fortress in the scorched black earth strewn with corpses, braving the suffocating hot air. At this time, around the Boulder Fortress, a colorful light suddenly appeared, and the defensive barrier was about to be opened.

The Red Moon Demon King snorted coldly.

Those ghosts reunited, converging into a whole, and suddenly launched another "scream of pain", which directly caused the spell to be interrupted again, and the defensive barrier that was originally about to be formed was now useless at all.

Ghosts have a certain psychic attack.

A single ghost can't pose a threat, but if you want the Red Moon Demon King to do this, integrate more than ten or two hundred thousand spirits to interfere, and the entire fortress will not want to send out another spell unless it reaches a master above the geomagician!

Mu Yun frowned.

What should I do?

Mu Yun's strength alone is small, and it is impossible to shake the defense of more than 100,000 spirits united, but a way can always be thought of, and the top priority is to prevent the further invasion of the demon army. Mu Yun had to launch the third trap, and the land in front of the steel fortress suddenly softened in a large area, and in a very short period of time, it turned into a large bottomless swamp, and the swamp was also covered with all kinds of wood-based entanglement traps.

When the undead accidentally pass through the swamp, they are immediately restrained by vines and quickly pulled into the swamp.

At this time, the distance between the two sides was already very close, the demon army was attacked by the most intense attack, and the entire battlefield was full of black smoke and miasma, thick smoke, dust, poisonous fog, and clouds, and the daylight became no different from the night, and there was no trace of sunlight shining in at all, and the darkness completely enveloped this side of the world.

Gargoyles, ghosts, hawkmen, all kinds of flying combat units circled around the fortress, attacking from time to time, hundreds of spells roared in, and under the indiscriminate bombardment, the Terran warriors desperately resisted and forcibly blocked it outside. In contrast, these were just harassments, and the real danger was the main force on the ground, dozens of abominations had already walked in front of the swamp, apparently preparing to get through the swamp.

The Demon King's eyes shot out a beam of light.

The whole swamp hardened in an instant, and Abomination swaggered over the swamp, and finally came to the fortress, and the dense heavy crossbow arrows attacked, already shooting the abomination's body into a hedgehog, but the abomination had no effect at all, and began to attack the thick parapet.

That's a lot!

I can't finish killing it at all!

The endless demon army makes people feel powerless.

The demon army is not only huge, but the more terrifying thing is that whether it is the undead or the demons, they are all extremely tenacious existences, compared to the vitality of the human race, it is too fragile, if there is no fortress as a defense, these soldiers and horses will only have the fate of being crushed!
