"Kill, kill, kill!"

Looking at the hundreds of mana realm ironclad bulls that were rushing towards them, the five hundred mana realm monks among the three thousand guards in Black Mountain Town roared angrily, frantically agitating the mana in their bodies, urging the magic weapon flying sword, and quickly slashing towards the ironclad bull's body, wanting to kill the ironclad bull on the spot, so that it could not crash into the city wall of Black Mountain Town.

It's just that the ironclad bull is covered with iron armor, and its defense is extremely powerful, and the magic weapon long sword guarded by Black Mountain Town can't break through the ironclad bull's defense at all, and can only stir up bright sparks on the ironclad bull's iron armor.

"Kill them all!"

At this time, Lin Xue took Zhao Yuan and other demon slaves to the city wall of Black Mountain Town, looked at the hundreds of mana realm ironclad bulls that were rushing over, and immediately ordered Zhao Yuan and the other demon slaves loudly.

Whoosh! Whoosh!

As soon as Lin Xue's voice fell, the sound of breaking the air sounded on the wall of Black Mountain Town, and Zhao Yuan and other demon slaves turned into a streamer one after another, and rushed straight towards the iron-armored bull, and the magic weapon flying sword in his hand, with an extremely sharp edge, slashed towards the iron-armored bull's body.

Bang! Bang!

In the crisp sound of metal collision, the flying swords of Zhao Yuan and the other demon slaves easily broke through the iron armor defenses of the iron armored cows of the mana realm, pierced through the bodies of the iron armored cows, and killed them on the spot.

Roar! Roar!

Seeing that his companion was killed by Zhao Yuan and other Yin-Yang Mirror Demon Slaves, the surrounding ironclad bulls let out angry roars, their mana surged, and the sharp horns on their heads flashed with cold cold light, and they slammed straight into the bodies of Zhao Yuan and other Yin-Yang Mirror Demon Slaves.

It's just that Zhao Yuan and the other Yin-Yang Mirror Demon Slaves only retained their fighting instincts, and had no other autonomous consciousness, and in the face of the attacks of dozens of Mana Realm Ironclad Bulls, they did not have the slightest fear, and directly urged the magic weapon flying sword in their hands to meet dozens of Mana Realm Ironclad Bulls and collide with them.

Boom, boom, boom!

In the midst of the violent roar, Zhao Yuan and other more than ten Yin-Yang Mirror Demon Slaves and dozens of Mana Realm Iron Armored Cows launched a fierce confrontation, and one by one the Iron Armored Cows were killed by the magic weapon long swords of Zhao Yuan and other Yin-Yang Mirror Demon Slaves, becoming broken corpses one by one.

In a matter of moments, dozens of ironclad oxen were all killed, while Zhao Yuan and more than a dozen Yin-Yang Mirror Demon Slaves only died, and the others only suffered some trauma.

Roar! Roar!

At this time, angry roars came from afar, and one after another demon beasts rushed towards the direction of Black Mountain Town like a tide, a posture that wanted to submerge Black Mountain Town.

"Attack freely, be sure to block the monster's charge for me!"

Looking at the dense demon beasts that could not be seen at a glance, a look of determination flashed in Lin Xue's eyes, and he ordered loudly.

Suddenly, I saw only a famous Black Mountain Town warrior and guard, who agitated the true qi, true yuan, gang qi, and mana in their bodies, condensed one after another fierce attacks, and bombarded the charging demon beasts directly, killing the demon beasts one by one, causing them to die tragically on the spot and fall on the way to the charge.

It's just that there are too many demon beasts, tens of thousands, and the attacks of the warriors and guards of Black Mountain Town are like a drop in the bucket, and they can't help at all, and they can't stop the charging of the demon beasts.

"Rain!"

Seeing this scene, a look of determination flashed in Lin Xue's eyes, and he snorted lightly, the mana in his body surged rapidly, and a large range of offensive spells in the Xuanshui Jue were cast.

Suddenly, only drops of rain were seen condensing outside the town of Montenegro and scattering downward.

Bang! Bang!

In the crisp sound, a drop of rain was like a sharp arrow, easily piercing the bodies of monsters, killing monsters on the spot, and turning them into broken corpses.

In a moment's effort, tens of thousands of demon beasts were pierced by the rain, and died tragically on the spot, a large number of demon beasts fell weakly, and the momentum of the demon beasts' charge slowed down.

Roar! Roar!

Seeing that the rain's attack was so ferocious, the mana realm demon beasts and yin-yang mirror demon beasts that blocked the rain's attack let out angry roars one after another, their eyes flashed with fierce light, and they rose into the air and galloped straight in the direction of Black Mountain Town

"Master, I did my best, and it's up to you next!"

After casting a large-scale aggressive spell, Lin Xue's face instantly turned extremely pale, and she turned her gaze for help to Yang Rui's body.

"Rest well!

Seeing Lin Xue's appearance, Yang Rui nodded lightly and said in a flat tone.

After speaking, Yang Rui set his eyes on the mana realm and the Yin-Yang Mirror demon beast outside Black Mountain Town, his expression remained unchanged, the mana in his body surged, and the ten thousand demon seals were unfolded, and one by one the magic seals composed of mysterious runes were condensed, with terrifying power, bombarding the demon beasts outside Black Mountain Town.

Bang! Bang!

In the midst of a crisp sound, the mana realm and the yin-yang mirror demon beasts that were charging in front were hit by the terrifying magic mark one after another, and their bodies were like kites with broken strings, throwing them backwards.

At the same time, mysterious energy emanated from the magic seal, fused into the flesh and soul of the mana realm and the yin-yang mirror demon beasts, transforming them into demon slaves with only combat instincts.

Immediately afterwards, the Mana Realm and the Yin-Yang Mirror Demon Beasts that had become demon slaves immediately let out angry roars, waving their sharp claws, launching fierce attacks on their companions, killing and devouring the Mana Realm and Yin-Yang Mirror Demon Beasts one by one.

Roar! Roar!

Seeing this scene, the Divine Power Realm demon beast hidden in the rear let out angry roars, revealing its body directly from behind, turning into a black lightning bolt, and speeding straight towards Yang Rui's side, looking like they wanted to kill Yang Rui on the spot.

"Ten Thousand Demon Fist!"

Looking at the Divine Realm Demon Beast that was rapidly approaching, Yang Rui's expression remained unchanged, he snorted lightly, the mana in his body surged, and the Ten Thousand Demon Fist was unleashed, a big fist was condensed by pure mana, and one by one illusory demon shadows were attached to the fist, with terrifying power and monstrous demonic energy, and bombarded straight towards the body of the Divine Realm Demon Beast.

Roar! Roar!

Feeling the terrifying power contained in the fist, the demonic beast of the Divine Realm let out an angry roar, the mana surging all over its body, and the fire divine power unleashed, and a fire sword condensed from the flames slashed towards the fist.

Thundered!

In a violent roar, the fist and the fire sword collided together, and the demon shadow on the fist instantly submerged the fire sword, extinguishing the fire energy in the fire sword, turning it into nothingness and disappearing into nothingness.

Immediately afterwards, with a terrifying power, the fist bombarded the body of the Divine Realm Demon Beast unabated, directly shattering the body of the Divine Realm Demon Beast, turning it into a sky of flesh and blood, and died tragically on the spot.

"It's such a terrifying strength, it actually killed a Divine Realm demon beast with one punch!"

"The master guarding the town is so powerful, he actually killed a Divine Realm demon beast with one punch!"

"With the master guarding the town, our Black Mountain Town will be as stable as Mount Tai, not afraid of the attack of the beast tide!"

"The tide of beasts has receded, and we have won!"

“、、、、、、、、”

Seeing that the demon beasts of the Divine Power Realm were killed by Yang Rui with one punch, and the demon beasts of the Mana Realm and the Yin-Yang Mirror were either transformed into demon slaves by the Ten Thousand Demon Seal, or were killed by demon slaves, the warriors and guards above the city walls of Black Mountain Town let out excited cheers one after another.

"Lin Xue, this time the beast tide is a little strange, I'm going to the Black Mountain Range to check the specific situation, and the matter here will be handled by you!"

Yang Rui ignored the cheers of the surrounding soldiers and guards, explained to Lin Xue on the side, and handed over the control of the demon slave to Lin Xue, so he mobilized the mana in his body, took off into the air, and galloped away in the direction of the Black Mountain Range.

Soon, Yang Rui crossed the distance of 100 miles and came to the outside of the Black Mountain Range, and was surprised to find that most of the demon beasts in the Black Mountain Range had left the Black Mountain Range, and only a few weak demon beasts remained in the Black Mountain Range.

When Yang Rui went deep into the Black Mountain Range for dozens of miles, he was even more surprised to find that the demon beasts in the depths of the Black Mountain Range had already fled, and they couldn't even find a single demon beast, which made Yang Rui surprised, and while continuing to advance towards the Black Mountain Range, he secretly raised his vigilance.

Soon after, Yang Rui penetrated more than 100 miles into the Black Mountain Range, more than one zhang high, more than three zhang long, with a huge silver shell, eighteen silver beetles with small legs like sharp swords, entered Yang Rui's field of vision, making Yang Rui's eyes flash a look of surprise, and involuntarily exclaimed softly: "Zerg silver beetle!"

The Zerg is a very terrifying race, the vast majority of the Zerg are unconscious, only the combat weapons of combat instinct, and only a small number of female insects and Zerg commanders have wisdom and command countless Zerg warriors.

The Zerg has a terrifying reproductive ability, as long as there are sufficient energy and mineral resources, they can continuously produce all kinds of Zerg warriors, and then invade the Quartet to obtain more energy and mineral resources, and then produce more Zerg warriors, forming a terrifying cycle and expanding unlimitedly.

In view of the Zerg's terrifying reproductive ability and aggressive instinct, the Terran, Demon, and Demon Clans of the Ten Thousand Demons Secret Realm joined forces to suppress the Zerg in one area of the Ten Thousand Demons Secret Realm, making it impossible for other areas.

Now, there were traces of the Zerg in the depths of the Black Mountain Range, which made Yang Rui very surprised, and secretly guessed whether there was any loophole in the defense line of the Terran, the Demon Clan, and the Demon Clan against the Zerg, which allowed some Zerg warriors to enter the Terran area.
