"What if you don't have to seal the magic chest?" asked Berg with a smile.

"That can be stored for a hundred or two years, right? The base fluid is used for blending, and if it is made into various finished products, it will last longer. ”

"Wouldn't that pollute?"

"No, there is still a recycling value, so you won't lose money if you buy it back. ”

"Do synthetic formulas sell?" Berg asked for not a base fluid formula, but a specific variety of practical technical formulas.

"The weapons side can be sold. ”

Berg nodded, but on the other hand, the other party didn't sell it on the city construction side, and this was normal. However, Metatrin didn't need to change anything in terms of urban development. The other party has this technology, so this material is used. Metatrin's city construction is just as good as it is and has its own cost configuration.

Since it is to buy base fluid, it is used to make weapons.

Rhode Island was willing to sell weapon recipes, saving Metatrin a lot of time.

In the room below the stands, two squadrons searched one by one, and in each room, there were corpses. It doesn't take much thought for the information to come in again.

"The souls of the people here have been taken away. At least most of it was taken away. ”

Berg frowned and asked, "How are the mages?"

Someone below replied: "The state has basically recovered, mainly the Void Magic Monument has been erected, and there is no problem in the arena, including the periphery of the stands." ”

"Hurry up, I'm going to get this arena done before dawn. You all should do it. ”

The other five legends nodded, and Phoenix simply took his command squadron and personally killed the stands. The Mithril Swordsman construct, his legendary version, a huge magic sword, is just an empty shell. Inside the empty shell was the sword qi that Medirli had prepared for him.

Enough sword energy for him to squander.

For sword cultivators, the sword qi that can be stored is like a magician's scroll. Medierli's subordinates have a lot of sword cultivation, and they usually practice, and they all have this training project, which is to store the purest sword qi made by themselves.

In this process, a lot of sword qi will be born that are not very satisfying.

It's not that it's not powerful, it's that it's not pure enough. These sword qi are collected by Medir Lidu and changed by hand. What was given to Phoenix this time was the sword qi that Medirli had refined.

But the upper limit of the level, the highest is equivalent to Phoenix's own sword qi.

The Mithril Swordsman is more than eight meters tall, and the giant sword is also more than seven meters long, and the amount of sword qi stored inside the sword body is equivalent to a good sword bag.

Phoenix didn't shoot directly during the whole process, and after going to the stands, he watched from the sidelines, and when he saw who was in danger, he was far away from urging the sword qi to slash over, and used himself as a magician.

What he mobilized was only a sword qi equivalent to a five-grade sword cultivator, and the sword qi showed a faint golden color, only the length of a finger. But from beginning to end, Phoenix urged this sword qi to fight, and it only consumed about one-fortieth.

This sword qi was incomparably sharp, and when it fell on the monster, it directly cut the monster, and the wound was as smooth as a mirror.

The rest of the legendary mages, like him, watched the battle cautiously and rarely made a move. The suppression of the laws of a world has the deepest impact on legendary mages. Although their combat effectiveness has not decreased much.

All the mages, as well as the magical structures that can be built to help them, are on their toes.

The arena was much larger than normal, and there were partitions and tables next to the seats in the civilian area. There are also many rooms under the huge stands.

Construction robots excavate in the cleared area and re-plan the design. At the bottom, hundreds of meters underground, you need to extend the magic network and create a defensive ring below.

It's terrible to be broken in from below, but fortunately, people in the Overworld are very skilled at this.

All the upper and lower water pipes in and out are sealed, and the constructed petrification is thrown out like money, and layers of dirt are permanently petrified, and the entire underground is to create a thick shell. Further up, below the stands, there is a thick layer of rock. The rooms were converted to serve partly as barracks and partly as storehouses for battleships.

The battleships brought this time, the legendary mages have not been released yet, but they can't always be stored in the space equipment, and the spirit of the mages is consumed a lot, which is a pressure.

The entire arena, originally had twelve gates, four expanded, and the rest remained unchanged.

The arena itself is like a huge circular castle, with a perimeter height of hundreds of meters. Because the stands are gradually raised upwards, this structure is not unusual.

Metatlin's renovation plan was to dig caves hundreds of meters deep into the earth from above the stands. Then in the cave **, pour artificial stone.

If artificial stone is poured, the quality is usually slightly inferior, but the construction speed is fast.

In this way, stone pillars with a diameter of several meters were laid down in the stands that surrounded the arena. Then the robot continued to make holes underneath, so that between the stone pillars, there are also artificial stone connections.

The whole arrangement of the huge magic net, this is also a huge project.

It seems that the Metatrin family brought such supplies with the intention of building a small fortress of their own.

Although most of the souls were taken away, some surviving souls were found. In addition, those monsters themselves are also intelligent, albeit chaotic creatures.

The magicians pieced together and got more and more information.

This city should be completely finished, because the city temple has been destroyed. The second place to be destroyed is the Demon God Arena with a spatial passage.

The Temple of the God of Magic, already occupied by invaders.

And this city, with a population of more than five million, is one of the largest cities in the world, and there are no cities of this size in the main world.

Perhaps for some of the tech world, a city of five million people is nothing. But on the Overworld, cities are never that big, and they don't build skyscrapers and stuff people into them.

And this world is not a world of technology, it is a world ruled by the god of magic, and the tallest building in the city is the temple, and then the magic tower. Civilians live in small houses of two or three floors. If such a city has more than 5 million people, the area will be very large.

The world of the god of magic has been invaded, and it is no wonder that the god of magic on the other side of the main world has not been able to get the support of the main body.

It's a lot of trouble, but my own group of people are trapped here, and I don't know what's going on here. Six people entered, in one world, purely by accident. If the rest of the Overworld is coming through the passage, they need clear coordinates.

This has to be actively communicated, precise calculation, a year's time, is less to say.

Fighting independently for a year, alas......

Berg sighed in his heart, it was not easy to fight alone, not to mention that everyone's strength was limited.

It's okay around the magic tower, but if you go further, your combat power will be as seriously damaged as when you first entered this world.

With such a huge arena, on the side of the Overworld, you can build a small city.

Let's defend this place first, the space passage can't be lost.

At the edge of the arena stands, a large number of robots go up to defend, and there are combat structures. Because the arena is the second place to be washed in blood, there are not many monsters.

The monsters that completed the mission have gone somewhere else.

Those who remained were monsters like Soul Eaters searching for remnant souls.

"My lord, we can communicate with deep space!" said the magician with Metatrin excitedly coming over to report.

Berg is also in good spirits, because he can communicate with deep space, and he can make the magic tower release some powerful magic. This world has been invaded by chaos, so if you deal with monsters, the effect of order magic will be very ideal.

Such as the Elemental Judgment, the Light of Order, and so on.

These magics are still more troublesome for human mages to use, but if they are activated by a magic array and backed by the power of deep space, they are quite simple magic.

The stone pillar he asked the mage to pour was called the Order Pillar Stone, and it was not easy for chaotic creatures to destroy it.

The edge of the stands, further out, is actually the realm of the arena, with shops and even large hotels for lodging. This arena should be the largest within a radius of thousands of miles, and there may be outsiders coming to watch.

The arena is relatively closed, and it is easy to clean up, but outside the arena, if you go out to fight, it is unlikely that you will not attract attention.

Berg pondered as he checked the progress of the Magic Tower.

"My lord, the storehouse of the battleship has been built. ”

"My lord, the chariot storehouse has been built......"

The following news came up one by one, and Berg said: "Everyone arrange the battleships and chariots, arrange an artillery position around the magic tower, adjust the angle, and only care about the distance of ten miles around." ”

Naturally, there are people below to do things, and Berg himself goes to the storehouse of the battleship and the chariot to release the space equipment and materials in the same way.

Something the size of a battleship, if it is released, consumes a lot of mental power at one time.

By the time everyone was done, even Phoenix felt a little tired. But he didn't take the ichor, he just went back to his Mithril swordsman construct to breathe.

"Let the soldiers rest for an hour, and after an hour, clear the perimeter of the arena. Berg said.

When the soldiers below heard the news, they were not surprised, this kind of thing happens often, and there are fixed in the training program.

However, when going out to fight, everyone has alchemy potions to take, which can make people fall asleep quickly, and when they are awakened, just drink some cold water. This potion is considered a valuable item on the soldiers' bodies, and an hour is enough for them to recover most of their energy.

"My lord, the sub-magic tower has also been built. ”

"Well, let's all go to the sub-magic tower to rest, Phoenix, you ......"

"It's the same for me, I have a little spellcasting skill. "Phoenix Road.
