On the periphery of the Demon God Arena, a circle of earth platforms was built and quickly petrified. Under the outer wall, which is nearly 120 meters high, it is more than 50 meters high, but the width is only 10 meters.

Once the earth and rocks have been tamped, they can be easily petrified with the lowest level of petrification.

And Metatrin has prepared a petrification magic array, which is carried by a robot and moved to cast spells, and the magician can quickly release a large area of petrification as long as he spends some mental power.

This is how Metatrin built a city quickly, and if he invaded the Atlas, he could quickly create a strong fortress.

The stone platform, like the inner stand, has an orderly pillar stone inside, which connects to the main magic tower, which will gradually strengthen this stone platform, which is equivalent to adding another layer of city walls.

And outside this table, a platform 20 meters high was built, which is the outermost part, with a width of 15 meters.

Although the stands of the arena were made by magicians, they were already very strong, after all, they were not fortresses, so the mages of Metatrin had to be remodeled.

The arena was too big, as large as an army of 6,000 men, and it was impossible to defend it at all. That is, the army of the main world is equipped with hundreds of thousands of robots, otherwise the army will be overstretched.

That's it, Berg still has to calculate whether to activate all the spare robots.

Before the project outside the walls was completed, a large number of monsters poured in, as well as the army of those black people.

The blacks are tall, averaging two meters tall, and they don't look like spellcasters, but they can command monsters. With the monster commanded by the black man, it no longer fights by instinct, and it seems very orderly.

Finding that the robots' guns are extremely lethal, those monsters do not approach on the streets, but use cover to try to sneak up on the army of the Overworld.

In the sky, dozens of fruits gave birth to wings and turned into flying monsters!

It's a bit of a demon, but it's definitely not the kind of demon in the demon world.

God knows where these things came from!

"There are fifty-six in heaven, and I will ask for two more, and nine for each of you. "Berg spotted a flying monster approaching from the sky.

The nine flying monsters, in Phoenix's mirror, turned red, and this was his disposal.

Phoenix released nine sword qi in an instant.

As soon as the sword qi flipped in the air, it flipped from below to above, and stabbed down on the monster's back. Although those flying monsters were very dexterous, how could they be dexterous enough to surpass the sword qi of sword cultivation.

Nine sword qi fell, and the nine monsters were cut in half, and then received an attack from the power of the sword qi, and their flesh and blood were shattered.

The sword qi flew back, Phoenix frowned, there was a faint blood light on it, it was polluted!

You must know that the sword qi of sword cultivation is very pure, and it is difficult to be polluted.

Phoenix had to use his own sword yuan to refine the nine sword qi. However, he still didn't dare to take it back, so he had to take out nine blank sword runes and absorb the sword qi into them.

He was afraid that if he didn't deal with it, he would also pollute the other sword qi in the magic greatsword.

Nine blank sword runes, after absorbing the nine sword qi, the level was instantly promoted from level twenty to level thirty-five. However, the sword talisman itself is not as fine as the sword qi in the sword bag.

These nine sword qi, under the control of Phoenix, instantly killed the nine-headed monster, and the nine-headed monster didn't even have the ability to dodge.

If it's a sword rune, although the level is high, the control is not so subtle.

The advantage of the sword talisman is that it takes a long time to use, unlike the simple consumption of sword qi. However, the sword qi itself changes flexibly, as if there is no entity, and the sword cultivation is infinitely subtle and intriguing.

Moreover, the control of sword qi consumes very little for sword cultivation. If you control the sword rune, although it is easier than controlling the flying sword, the consumption is not less than half.

After Phoenix dealt with these sword qi, the rest of the legendary mages took out the remaining flying monsters.

The speed was already very fast, and Berg said, "We've got attention, let's start fighting with artillery." ”

At the top of the six magic towers, one by one, real magic eyes floated and began to be responsible for scouting the surrounding enemies. These magic eyes communicate with the nine-story magic tower in the center of the arena, and can quickly process information.

At the same time, on the edge of the arena stands, there were also quite a few small MONOCULUS equipment lit up.

After these magic eyes are activated, all fixed magic cannons can be aimed at coordinates in an instant. And the technology artillery is only calculated by the robot that needs to be controlled, and the slowest calculation speed is within a second.

The sound of artillery in the arena immediately rang out, and those monsters who were looking for houses as cover were immediately blown to pieces by the shells along with the houses.

Powerful computing power makes the artillery extremely accurate, the shock wave of the explosion, will not hurt your own team, and try to destroy as many houses as possible with every shell.

In this way, the task of cleaning up the surrounding buildings is much easier.

The Demon Tree lost more than fifty fruits, and suddenly sensed the movement of the artillery, and immediately became vigilant, this is the power of the combination of the magic world and the technological world, and this kind of thing usually happens in large worlds.

The laws of a small world are not so complicated, and with magic, often technology cannot be developed. In the world of technology, magic cannot be born.

Even the medium-sized world is prone to conflict of laws and cause turmoil.

Only in large worlds will there be a coexistence of magic and technology, and the underlying laws are quite broad.

Things are more troublesome than you think, then you have to speed up the progress, relying on those demons, you can't get a large world army. However, the harassment is still to be harassed, and the spatial passage of the arena has been destroyed a lot, even if there is an army coming, it is a coincidence.

The number of opponents is limited, as long as there is no accident on their side, if there are a few more months, they can be swallowed up.

Thinking of this, the magic tree didn't care about those subordinates. Its trunk swelled suddenly, and a rattling sound sounded, and the temple's already somewhat dilapidated buildings crumbled one after another, and bricks and stones flew wildly. After the collapse of the temple, the Demon Tree revealed its true form, a banyan-like magic plant that covered a vast area, with thick branches hanging down.

A tree becomes a forest.

Above the canopy, there are many fruits hanging there, and the colors are chaotic. The largest of them were already faintly purple-gold, and the smallest fruits were white.

Between the roots of the demon tree, countless corpses were piled up, some of them had turned into white bones, and some were still turned into flesh.

The white bones that had been swallowed up stood up one by one, and the purple-gold lines on the skulls spread, exuding a black aura, which radiated outward, gradually wrapping the entire white bone, constantly twisting, and finally turning into black armor.

On the armor, there are purple-gold lines.

One by one, these black-armored warriors who were transformed into white bones stretched out their hands, inserted their two ribs, pulled out two ribs, turned them into two scimitars, and held them in their hands.

Under the urging of the Demon Tree, the black-armored warriors grabbed their scimitars and walked towards the periphery of the Demon Tree, standing solemnly by the side one by one, guarding the Demon Tree.

These are not undead, there is no soul fire, what allows them to move is the purple-gold pattern on the armor.

The purple-gold pattern, like a soul fire, will beat slightly, twist, and express things that make people unpredictable.

Around the ruined temple, monsters continued to drag corpses and throw them into the roots of the magic tree, which immediately branched into tiny branches and inserted into the corpses, absorbing flesh and blood.

A Soul Eater came running and spat out clumps of jelly-like stuff, which were also absorbed by the Demon Tree.

The Magic Tree seemed to be asleep, and it seemed to be half-asleep, and in a trance, it saw the commander of the army, recruiting all the generals like it in the city, and slaughtering into the kingdom of the god of magic.

What a wonderful thing it is to devour human beings, angels, saints, and heroic spirits in the kingdom of God, that is the most delicious thing.

Demon God Arena.

It has been changed beyond recognition and has been converted into a fortress.

Thousands of Pillar of Order are planted around the fortress to keep the arena fortress safe. In the center of the arena, there is a nine-story magic tower, as the sky brightens, this magic tower is initially completed, and it is connected with the six small magic towers around it, forming a huge magic network.

In the small magic tower, the Void Magic Monument was also installed.

The seven Void Magic Tablets make the laws around the arena and inside tend to the original appearance of the main world, so that the professionals are no longer suppressed by such powerful laws.

Every hour, only twenty percent of the magicians are resting, and the rest of the magicians are all busy.

Fortify, fortify all fortress buildings.

The artillery roared, and the buildings around the Arena fortress had been razed to the ground. A large number of monsters were killed by artillery fire, and the surrounding area of 500 meters has been cleared.

There was nothing left to get silently close to the Arena Fortress, and those small portable artillery pieces were enough to cover the perimeter. The destruction continued, and Berg demanded that everything be bulldozed within a kilometer radius of the arena. However, the ammunition consumption of the artillery is a bit large.

Now the monsters don't dare to approach, and it's not worth it to simply destroy the building.

Another squadron, leading the robots to the demolition.

"My lord, the soldiers need to rest, why don't you make it simpler and set fire to the things around you?" suggested the magician with Metatling.

"It's fine. Berg said, "Let everyone withdraw and rest for eight hours." ”

The surrounding soldiers, one by one, withdrew, only the magician did not stop working, but they were all half resting and half continuing.

"Now that we've settled down, let's discuss what to do next. Berg communicates with the other five legends and studies countermeasures. This world, which belongs to the god of magic, has been invaded.

Things were different from what he thought, and he couldn't figure it out.

Why, the corpses of the entire arena were rummaged through, and the clergy of the god of magic could not be seen?

Just as Berg was asking the question and everyone was thinking, suddenly, it was dark.

It was about eleven o'clock in the morning, why was it dark?
