The attack of the Netherworld biota was still scattered at first, but after three days, after the space-time rift was already covered with the corpses of creatures, the high-level creatures of the Netherworld arrived.

The creatures of the Netherworld attacked the rift in time and space, and began to form an orderly and simple formation.

Li Xiaotian and the witch swordsman, at the rift in time and space, at the temporarily erected lookout tower and city wall, saw that the army of creatures in the distance had gathered according to the type.

Populations such as reptiles, hydras, flying insects, rhinoceros, etc., are classified according to their speed of action and remote progress.

Li Xiaotian looked at the defensive magic array made by him and the witch swordsman, the defensive magic array on the periphery had been seriously damaged, and the creatures of the netherworld had now begun to not only carry out process attacks, they first sent out long-range attack creatures, and after a few rounds of long-range attacks, the magic array defense system would be broken and damaged, and the energy supply would not be available.

Then a large number of land battles and airborne creatures forcibly charged and destroyed.

The corpses and magic arrays everywhere were constantly broken.

"Let's go and kill these leaders who command the creatures of the Netherworld, in this way, our magic array will not be able to withstand it for a few days, and when the time comes, this task of defending the enchantment will take more than twenty days, and we will not be able to hold it for more than twenty days at all by relying on the two of us." The Witch Swordsman, the first protector of the Scarlet Alliance, looked at the current situation and said to Li Xiaotian worriedly.

"Wait, the corpses are not enough, the number of strong people who have died in the Netherworld is not enough.

We are now rushing into those high-level biota of the Netherworld, that is, to send them to death, the difference in numbers is too much, relying on the two of us, even if we find their leaders in the mountains and fields of the Netherworld biota, it is useless to kill them all.

These Netherworld creatures will continue to have more advanced powerhouses coming, and we can't kill their leaders at all. You command the defensive magic array, and you can resist it for about ten days, and I have a way to summon a group of warriors to help us guard for about fifteen days. Li Xiaotian said to the witch swordsman.

－－－

The battle continued, and the Netherworld biota attacked day and night in these days, and on several occasions, super creatures were sent to test the attack on Li Xiaotian and the witch swordsman in the center of the space-time rift.

However, before the defensive magic array was completely ineffective, these attacking super powerhouses constantly had to be subjected to the ferocious counterattacks of Li Xiaotian's powerful mecha after wearing it, and they also had to resist the attacks of the gathered energy from the magic array controlled by the witch swordsmen around them.

－－－

Li Xiaotian and the witch swordsman had resisted the attack of the netherworld creatures for fifteen days, and the witch swordsman at this time no longer had the confidence she had in the past, and the dust and blood on her body were all over her body, just like a person caught out of a pile of blood.

The Witch Swordsman had been fighting for fifteen days in a row, and her eyes had become a little glazed, even for her, a legendary-level powerhouse, facing fifteen days of continuous combat control and command, it made her feel exhausted.

Fortunately, Li Xiaotian has a strong breeding mecha that has a chip to assist the combat command program, controlling most of the magic defense system, and helping the witch swordsman share a lot.

Fifteen days of fighting, the defense system of the magic array has been damaged, and it has been completed into a complete set of fortifications.

As for the underworld biota in the distance, the number is increasing as time goes by, Li Xiaotian preliminarily estimates that there are hundreds of thousands of creatures outside, and the number is still increasing because of the attraction of the sealing magic array at the space-time rift.

"Are we going to fail! What about the helpers you are talking about! The witch swordsman asked Li Xiaotian in a hoarse voice, she had asked Li Xiaotian the same words several times these days, and the witch swordsman felt a little desperate, Li Xiaotian had no helper at all, how could Li Xiaotian summon any helper in the netherworld!

The witch swordsman felt that Li Xiaotian had said that she had a helper these days, and she only said it when she raised her confidence to fight.

The ground began to tremble, and many Netherworld creatures began to charge towards the rift in space. Birds, flying insects, flying snakes and other creatures in the sky also began to gather and charge. The number of Netherworld creatures attacking this time is even greater than the previous ones.

The witch swordsman analyzed and felt that it should be the leader of the netherworld creatures in the distance, and felt that the effect of the defensive magic array had been exhausted, and he was not ready to wait any longer, so he carried out a large-scale impact, preparing to defeat Li Xiaotian and the witch swordsman and destroy the sealing magic array.

And the witch swordsman felt that the fact was also the same, the defensive magic array, in front of this huge number of creatures, was just an ornament, and after destroying more than a dozen creatures, it was destroyed by hundreds of creatures that came up from behind.

Soon, numerous biota had rushed to the vicinity of the rift, destroying all magical defenses in their path.

The witch swordsman held the sword in both hands and prepared the last way to resist.

"Li Xiaotian, let's leave, these creatures are not something we can resist." The witch swordsman whispered to Li Xiaotian, and in the biota, she found a route to escape, and found some creatures that were relatively weak or slow to respond.

"It's just in time, and the show has just begun.

Come out, the warriors who are sleeping in the undead realm, the sacrifices of flesh and soul, have been piled up on the earth, and the souls of death and pain are howling in the air, waiting for the warriors to be harvested----" Li Xiaotian's mouth began to recite the ancient summoning spell, which was the positioning summoning spell agreed upon by Li Xiaotian and the leader of the female crystal archer of the undead realm.

As Li Xiaotian's ancient summoning spell was recited, he saw Li Xiaotian raise his hand and point in front of him.

The Emperor began to shake, and the space around him began to be disordered.

In the sky, large and small space entrances began to appear, riding bone birds, ancient dragons, undead knights, constantly flying out of the hollows in the sky, on the ground, there were also many time and space rifts, the first appeared is a row of undead five-headed horses, holding a big bone knife of death knights, followed by undead warriors, necromancers.

In the sky, on a silver-white bone dragon, sat a crystal skeleton archer wearing a blood-red cloak battle robe.

The necromancers holding the bone staff also came out of the space-time rift one after another.

The appearance of numerous undead creatures brought the aura of spatial death to its peak.

Netherworld creatures are soon attacked by the Death Knight, the Bone Blade.

Thousands of death knights began to run around the rift in time and space, shuttling, slashing swords constantly waving, cutting off the creatures in front of them and devouring the souls around them.

The undead warriors and the group of undead archers in the rear also began to attack the surrounding netherworld creatures.

You don't need to aim at all, the mountains are full of netherworld creatures.

The sounds of fighting, wailing, and the roars of creatures rang out constantly.

As a result of this change, several of the high-level creatures in the Netherworld biota jumped out, ready to block the group of death knights riding bone horses, but as soon as they acted, they were locked by the leader of the crystal skeleton archers in the air, and several undead bone arrows flew quickly, as if they had crossed time and space, directly shuttling through their heads and nailing their bodies into the earth.

The change continued, and the sudden appearance of the undead creatures station group only disrupted the rhythm of the netherworld creatures at the beginning, but the number of netherworld creatures behind them was amazing, and they didn't care about some damage in front of them, and they kept pouring up, pounced, and pounced into the battle.

The undead creatures quickly got together with the netherworld biota, and it was difficult to separate, and the undead female archer sitting on the bone dragon saw this result, and she also felt a little heartache for her subordinates, but she knew that there was no way now, she could only kill, kill, and kill all the creatures all over the mountains and fields, and her team could survive.

Li Xiaotian was in the rear, according to the calculation of the chip, and also seized the opportunity to launch the ancient undead creature summoning resurrection technique, for a while, as Li Xiaotian's magic covered the scene, many of the bones of the undead creatures that had fallen were reorganized again, and some of the dead netherworld creatures, their bones actually pierced out of the flesh, stood up from the ground, and began to attack the living creatures nearby.

Li Xiaotian is like releasing all the magical undead energy, and the effect of this undead magic is amazing, and the momentum of the Netherworld creatures that has just been condensed has hit the lowest point at once, if it weren't for the fact that there are too many Netherworld creatures in the back, the Netherworld creatures who are fighting want to run.

The witch swordsman standing next to Li Xiaotian was surprised to see this earth-shattering reversal, looking at the undead crystal shooter who controlled the bone dragon in the sky, and the tens of thousands of undead warriors on the ground, and couldn't close her mouth in surprise.

"Aren't you a warrior! You're still a necromancer? Where did you recruit these helpers? The witch swordsman asked Li Xiaotian in surprise.

"Actually, I am a double cultivator of magic and martial arts, my major should be considered magic, these are the undead legions I summoned, but the cost is very high, I can only summon it once now, the estimated duration, it will be more than ten days, and it will be difficult to summon in the future." Li Xiaotian said to the witch swordsman beside him.

Li Xiaotian could feel that the undead female archer was now directing her undead legion to fight, while absorbing the souls of nearby dead creatures, but the number of undead female archers was also being consumed, Li Xiaotian estimated that next time, the undead female archer would not be fooled to help him.

This time it's because the undead legion came up and fought with the netherworld biota, and now the fight is inseparable, and the undead female archer, the leader of the undead legion, knows that even if she opens the portal and ends this summoning, because the battle is in a stalemate, most of her subordinates will be wiped out by the netherworld creatures when they evacuate, and now they can only fight, and they can only fight back the netherworld creatures, and the undead legion can survive.

The undead female archer in the air, after glaring at Li Xiaotian on the ground, quickly waved her hands and released the undead bone arrows, attacking the strong people on the ground and some threats in the air.

Li Xiaotian also took the opportunity to launch the devouring ability of the strong breeding mecha to devour the flesh and blood energy of those strong people on the ground, and now the battlefield has become a mixed battlefield, like a meat grinder, Li Xiaotian did not expect it.

Creatures are constantly joining this battle, because of the energy released by the sealing magic array of the space-time rift, more and more netherworld creatures have been attracted, and these creatures, seeing the bloody battle, are also constantly joining it.

Fortunately, the undead warriors don't know how to get tired and can constantly wave their weapons to attack, and this time the crystal archer undead leader has almost called all her combat power, more than 100,000 undead armies, and undead all over the mountains, gathered around the rift in time and space, constantly harvesting the coming Netherworld creatures, every time they kill a Netherworld creature, the soul of the creature will be absorbed by the undead, which also makes the undead who are born in battle and still alive continue to evolve.

Of course, the undead are constantly being wiped out by the creatures of the Netherworld who come to them.

"The helpers you've summoned are amazing!" The witch swordsman waved her two-handed sword, fought beside Li Xiaotian, and said to Li Xiaotian.

"Save your strength, this fight will last for more than ten days." Li Xiaotian said to the witch swordsman beside him.

In the melee, flesh and blood, and souls flew on the battlefield, and the sealing magic array of the space-time rift also became faster and faster to complete the upgrade because of the sudden influx of many chaotic energies nearby.

The sealing magic array in the sky is evolving, but the bloody undead creatures and netherworld creatures have already forgotten their original intentions and are engaged in battle.

－－－

Fifteen days of battle continued, at the beginning of the melee more than 100,000 undead, now only more than 10,000 undead, the first appearance of the undead female crystal archer riding the bone dragon, the idle bone dragon did not know that it was broken by that creature, the undead female archer on the ground, brandishing bone spears and bows and arrows to join the battle, the remaining more than 10,000 undead, compared to when they came, the strength has increased greatly, after fifteen days of continuous fighting to devour the souls of the surrounding creatures, their original bones and soul flames, have become more powerful.

And the ground has been dyed red, at least five or six hundred thousand creature corpses, pushed into this battlefield within a radius of ten kilometers, Li Xiaotian directly participated in the battle at the beginning, and in the later stage, he simply shook on the battlefield, relying on the strong movement ability of the strong breeding mecha, it is difficult for any creature to catch his figure, Li Xiaotian controlled the strong breeding mecha to secretly absorb the energy in the flesh and blood of these dead creatures, and in the past ten days, the strong breeding mecha has also absorbed the energy.

The witch swordsman's two-handed swords have been numb in the past two days, and now the witch swordsman was arranged by Li Xiaotian to the side of the undead female archer, the undead female archer took a skeleton arrow to shoot, and the witch swordsman went to melee to help the undead female archer defend against the nearby netherworld creatures, and they cooperated very tacitly.

There was a loud bang, and then a dazzling white light appeared on the ground and in the sky, and the original space-time rift actually rose into the air, and a huge vortex quickly rotated in the air.

Within a few seconds when the creatures around him were stunned, Li Xiaotian quickly moved to the side of the witch swordsman, grabbed the witch swordsman, and jumped into the whirlpool.

Then, several fast-reacting Netherworld creatures also jumped into the whirlpool.

The vortex lasted tightly for two or three seconds before shutting down, as if it had never existed at all. The surrounding magic fluctuations disappeared in an instant, and even the space-time rift and the sealing magic array also disappeared completely, if they had never existed at all.

The high-level Netherworld creatures were stunned, the only space-time rift passage they were about to break through that could lead to another world was sealed and completely disappeared.

While these netherworld creatures were stunned, the undead female archer, the leader of the crystal skeleton, while cursing Li Xiaotian in her heart, also quickly issued an order to evacuate to her opponent, opened the magic array of reverse return, and opened the space-time rifts one by one, and the undead army quickly poured into it.

Some of the creatures of the Netherworld who are not afraid of death have actually pursued into the rift in time and space, and most of these unlucky creatures of the Netherworld have been lost in the process of time and space teleportation, even if a small number of them survived, they luckily entered the world of the undead, and they also became the food of the crystal female archer tribe, and they died quickly, not even leaving their bones and souls.

With the withdrawal of the undead legion from the battlefield, only the Netherworld biota remained, and some weak Netherworld creatures were quickly dispersed by the strong, and the powerful Netherworld creatures left behind explored the surroundings, but found that the space-time rift and magic seal had really disappeared completely, without the slightest trace.

Although they were a little unwilling, the masters of the netherworld biota could only take their respective biota and start to leave this bloody location.

Flesh and blood condense, allowing some weak creatures to approach the battlefield where they can become mad.

Because of the contamination of various flesh and blood, the corpses of creatures left here are inedible at all, and some creatures who are not afraid of death, after stealing and eating the corpses contaminated by the flesh and blood of many creatures, also remain on this battlefield forever and become wandering mutant monsters.

－－－

Li Xiaotian pulled the witch swordsman, and at the last second of the end of the seal, he successfully entered the space-time rift, and after the feeling of the world spinning, the witch swordsman almost fainted and fainted.

"Hurry up and protect your body with your own strength, we are about to pass through a deep hole of ice at absolute zero." Li Xiaotian reminded the witch swordsman beside him.

After hearing this, the witch swordsman thought about the cold and biting ice cave she had experienced when she first entered the Netherworld a few years ago, and felt that she had used the energy of her body to create a defensive shield around her body to resist, and the cold of the ice cave was definitely beyond the imagination of ordinary people.

Li Xiaotian took the witch swordsman and quickly lifted into the air, shuttling, Li Xiaotian found that there were six netherworld creatures with good strength behind him, but unfortunately, these creatures didn't know that there was an absolutely cold ice cave in front of them that could make them collapse.

Unguarded, these six creatures were taken into the ice cave that instantly warmed by Li Xiaotian and the witch swordsman.

The six unlucky creatures, their strength, if they were interestingly prepared, would have resisted the cold attack of the ice cave, but without preparation, all of a sudden, they entered the isolation temperature of the ice cave, and their appearance was instantly frozen, although they did not die immediately.
