A circle of earth platforms was built on the outer periphery of the Demon God Arena, and it quickly petrolated. Under the exterior wall that was nearly 120 meters high, more than 50 meters high were built on it, but the width was only ten meters.

When these earth and stones are compacted, they can be easily petrified with the lowest level of petrochemical techniques.

Metatrim prepared a petrified magic array, carried it with a robot, and moved it to cast the spell. As long as the magician put in some mental power, he could quickly release a large area of ​​petrified magic.

This is how Metatterin quickly built a city. If it invades another world, it can quickly create a solid fortress.

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

Outside this table, a platform that is twenty meters high is built, which is the outermost, with a width of fifteen meters.

Although the stands in the arena were made by magicians and were already very strong, they were not fortresses after all, so Metathrin's mages need to be remodeled.

The arena is too big, and the army of 6,000 people cannot defend at all. That is, the army of the main world is equipped with more than 100,000 robots, otherwise the troops will be short of strength.

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

Before the project outside the wall was completed, a large number of monsters and the army of black people came.

The black people are tall, and on average, they look two meters above. They don’t look like spellcasters, but they can command monsters. With monsters commanded by the black people, they no longer rely on instinct to fight, and they seem very well-organized.

It was discovered that the robot's guns were extremely lethal, so the monsters did not approach the streets, but tried to secretly approach the army of the main world with the help of bunkers.

In the sky, dozens of fruits grow wings and turn into flying monsters!

It has a bit of a demonic aura, but it is definitely not the kind of demon in the demon world.

God knows where these things come from!

"There are fifty-six in the sky, I want two more, and you are nine." Berger discovered the flying monster approaching from the air.

The nine flying monsters turned red in the mirror image of Phoenix, which was handled by him.

Phoenix released nine sword energy and arrived in an instant.

The sword energy flipped through the air, flipped from below to above, and stabbed the monsters on the back. Although the flying monsters were very agile, how could they be more agile than the sword energy of the sword cultivator?

Nine sword energy fell, nine monsters were slashed in half, and then they received attacks from the sword energy power, and their flesh and blood shattered.

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

You should know that the sword energy of the sword cultivator is very pure and difficult to be contaminated.

Phoenix had to use his sword energy to clean up the nine sword energy. However, he still did not dare to take it back, so he had to take nine blank sword talismans and absorb the sword energy into it.

He was afraid that he would not deal with it completely and pollute the other sword energy in the magic sword.

After absorbing nine blank sword talismans, the level was instantly promoted from level 20 to level 35. However, the sword talisman itself was not as delicate as the sword qi in the sword sac.

Under Phoenix's control, these nine sword energy instantly killed the nine-headed monster, and the nine-headed monster did not even have the ability to dodge.

If it is a sword talisman, although the level is high, the control will not be so exquisite.

The advantage of the sword talisman is that it has been used for a long time, not as fast as the simple sword energy consumed. However, the sword energy itself changes sharply, as if it has no entity, and the sword cultivator can control it infinitely exquisitely.

Moreover, controlling sword energy is very small for sword cultivators. Although it is easier to control sword talismans than controlling flying swords, it consumes more than half of it.

After Phoenix dealt with these sword energy, the rest of the legendary wizards killed the remaining flying monsters.

The speed was already very fast, and Berg said, "We have attracted attention and start fighting with artillery."

At the top of the six magic towers, real magic eyes floated up one by one and began to detect the enemy situation around them. These magic eyes communicated with the nine-story magic tower in the center of the arena, and could quickly process intelligence.

At the same time, on the edge of the arena stands, many small magic-eyed equipment lit up.

After these magic eyes are activated, all fixed magic cannons can instantly aim at coordinates and bombard. The technological cannons only need to be calculated by robots that need to be controlled. The slowest calculation speed is within one second.

The sound of artillery in the arena immediately sounded, and the monsters looking for houses were immediately blown to pieces by shells and houses.

The powerful computing power makes the landing point of the artillery extremely accurate. The explosion shock wave will not harm your own team. And try to destroy as much house as possible for every shell.

This makes it much easier to clean up surrounding buildings.

The magic tree lost more than fifty fruits, and suddenly sensed the movement of the cannon and immediately became alert. This is the power of the combination of the magic world and the technological world. Usually, this kind of thing happens in large worlds.

The laws of small worlds are not so complicated. With magic, technology often cannot develop. With technology, it cannot be born in the world of technology.

Even the medium-sized world is easy to cause conflicts of laws and turmoil.

Only in large worlds can magic and technology coexist, and the underlying laws are quite broad.

Things are more troublesome than you think, so you have to speed up the progress. With those demons, you can't handle an army in a large world. However, it is still necessary to harass it. The space channel of the arena has been destroyed a lot, and even if an army comes, it is a coincidence.

The number of the other party is limited. As long as nothing happens to you, you can swallow it in a few more months.

Thinking of this, the Demon Tree didn't care about its subordinates. Its trunk suddenly expanded and a crunch sounded. The already damaged buildings in the temple collapsed one after another, and bricks and stones flew around. After the temple collapsed, the Demon Tree showed its true shape. It was a banyan tree-like magic plant, covering a vast area, with thick branches hanging down.

A forest is formed by a tree.

There are countless fruits hanging there above the tree canopy, with chaotic colors. The largest of them are already faintly purple-gold, while the smallest fruit is white.

Between the roots of the demon tree, countless corpses were stacked, some of which had become bones, and some were still flesh and blood.

The bones whose flesh and blood were swallowed up stood up one by one, and purple and golden lines spread on the skull, emitting a black aura. The black aura spreads outward, gradually wrapping the entire bones, constantly twisting, and eventually turning into black armor.

There are purple and gold patterns on the armor.

These black-armored warriors transformed from white bones stretched out their hands, inserted them into their ribs, pulled out two ribs, turned into two scimitars, and held them in their hands.

Under the urging of the demon tree, the black-armored warrior grabbed the scimitar and walked towards the periphery of the demon tree, standing next to it, protecting the demon tree.

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

The purple-gold pattern, like soul fire, will jump, twist, and express things that are puzzling and unpredictable.

Around the destroyed temple, monsters were still dragging the corpses and thrown into the roots of the demon tree. The roots immediately split into tiny branches, inserted into the corpse, and absorbed flesh and blood.

A soul-devouring beast came and spit out a jelly-like thing, which was also absorbed by the demon tree.

The Demon Tree seemed to be asleep, and it seemed to be half-dream and half-awake. In a trance, it saw the commander of the army, recruiting generals like it in all cities, and entering the kingdom of the magic god.

What a wonderful thing to devour humans? The angels, saints, and heroic spirits in the kingdom of God are the most delicious things.

Demon Arena.

This place has been unrecognizable and has been modified into a fortress.

Thousands of order pillars were inserted around the fortress, maintaining the safety of the arena fortress. In the center of the arena, there are nine-story magic towers. As the sky dawned, the magic tower was initially completed and connected with the six small magic towers around it, forming a huge magic network.

The Void Magic Monument was installed in the small magic tower.

Seven void magic monuments make the laws around the arena and inside the main world look like they were, and make professionals no longer be suppressed by such powerful laws.

Every hour, only 20% of the magicians are resting, while the rest are all busy.

Strengthen, reinforce 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 500-meter range had been cleared.

There is nothing else that can quietly approach the arena fortress, and those small portable artillery cannons are enough to cover the surroundings. The destruction continues. Berg demands that within a kilometer range around the arena, everything will be flat. However, the ammunition consumption of the artillery is a bit high.

Now the monsters dare not approach, and simply destroying the buildings is not worth it.

Another squadron led the robots to demolition.

"Sir, the soldiers need rest. Why not just make it simple and set fire to the surrounding things?" Metattering's magician suggested.

"Okay," Berger said: "Let everyone retreat and rest for eight hours."

The soldiers around him retreated in groups, but only the magicians had not stopped working, but they were half resting and half continuing.

"It's settled down, let's discuss what to do next." Berg communicated with the other five legends and studied countermeasures. This world belonging to the God of Magic was actually invaded.

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

Why, the corpses in the entire arena were searching through, and the clergy of the God of Magic could not be seen?

Just as Berg asked this question and everyone was thinking, it suddenly became dark.
Chapter completed!
