The original restraint relationship between the four odd places happened to be a closed cycle.

The general restraint relationship is as follows:

To restrain the fire elemental, you need to have a [Water Orb].

Restraining the natural elements also requires [Fire Elemental Orb].

Restraining Earth Elementals requires [Natural Elemental Orbs].

Restraining the water elemental requires an Earth Orb.

And so on.

If outsiders want to intervene, they must use violent means to obtain the corresponding material of a certain type without the help of elemental orbs, and then solve it step by step.

In other words, the biggest difficulty in cracking these four elemental wonderlands is to break the cycle first.

Breaking the cycle first and then connecting to the cycle is the best way to attack the four elements of fire, wood, earth, and water.

The first element that Chen Xuan cut into was the lava lake.

It was the territory of the [Grumpy Fire Elemental], and he didn't have the [Water Elemental Orb] at that time.

The key to breaking the game is the liquid nitrogen that Chen Xuan carries with him.

With this as a breakthrough, Chen Xuan completed the strategy of the four strange places.

And its complementarity is simple and clear.

Now Chen Xuan has collected enough materials from all over the place.

When harvesting in the future, as long as you follow a specific law, the risk can be greatly reduced.

However, the Elemental Wonderlands are still dangerous.

And even if you master the Elemental Orb, there is still the law of complementarity and mutual restraint.

But unless Chen Xuan personally took action, if someone else handled this matter, there would still be risks.

And this risk cannot be reduced to zero.

So this matter needs to be considered in the long run.

After a little thought, he took one last look at Silver Lake and led the team away.

In order to collect [Elemental Orb] and [Water Elemental Essence] from tens of thousands of water spirits, he had already delayed three or four water clocks here.

Fortunately, the four circular markers have now been explored.

All that remains of the unexplored marker is the mysterious six-pointed star region.

Referring to the current location, Chen Xuan still had to return and drive a distance in the direction he came.

Then turn back on the right path.

It's going to be a relatively long journey.

You know, it took him two or three hours to get here from the exit of the Misty Canyon.

It is estimated that the car will have to drive more than two hours of water hours to reach the last location.

Wait until you've explored the six-pointed marker.

The entire Misty Mountain Range had no secrets for Chen Xuan.

And his intuition told him that it was the essence of the entire Misty Mountains.

So far, he has learned enough from this exploration trip.

There are a total of eight markers.

The three asterisk marks are Dark Gold Mine, Mithril Mine, and Orichalcum Ore.

The four circle marks are the four elemental wonderlands of [Lava Lake], [Willow Forest], [Mire], and [Silver Lake].

The above seven marking points have made Chen Xuan gain a lot.

Then the last six-pointed star marker marked by [Insight] as [Extremely Dangerous] became the top priority of Chen Xuan's expectations.

Of course, the gain and the effort are always proportional here.

If you want to get the benefit of this, you must first solve the problems that may arise!

But no matter what, Chen Xuan's heart was more expectant than apprehensive.

See the mountains and open the mountains, and pave the bridge when encountering water.

When there is a problem, it is to solve the problem.

He has never been cowardly before fighting.

With anticipation and determination in his heart, Chen Xuan drove the gas half-track truck on the way to the last marked point.

……

Just when Chen Xuan was busy opening up the two realms during this time.

The construction of the Atlas Mega City is also in full swing.

A large amount of resources that had previously been sealed in the city were unsealed.

Countless secret warehouses are opened.

Millions of people were urgently called up to participate in the construction of the outer defenses of the megacity.

The local Adventurers' Guild, Mercenary Guild, and Magic Guild were all called up temporarily.

Countless adventurers, mercenaries, and spellcasters have been lured by the high rewards to join the temporary expansion of the Atlas Megacity.

This move greatly replenished the strength of the giant city.

Warcastles have also sprung up on the periphery.

The indigenous people of the Naroa continent have a sense of planning ahead.

When the plague has not yet broken out, a large amount of emergency resources are often reserved.

Now, with the mobilization order in place, this batch of resources quickly came in handy.

They were transformed into defensive forts and fortifications.

Give Ataxus Megacity extra chips for the next apocalypse.

There are a lot of people passing through the gates of the giant city.

Many people did not disguise themselves at all, but wore a hood to cover the side of their face, which is quite common among travelers.

And the practicality of the pocket is undeniable.

It can not only shield the wind and sand, but also cover the face to a certain extent.

After passing through the passes from the outer line of defense, you can see the tall walls of the first circle of Ataxus standing with the naked eye.

This is the strongest line of defense in the Ataxx City, and the first line of defense against the City itself.

Compared to these towers, the walls of Magdam are children's toys.

The towers on the third floor of the Ataxus Giant City are hundreds of meters high, and the thickness is generally twenty or thirty meters.

The tower was wide enough for four or five carriages to run parallel above.

Not only that, but a rest room and storage room were built inside the castle tower.

This is also the origin of the name "castle tower".

It's both a building and a wall!

And as the perspective gradually approaches the Ataxus Big City.

Everyone could see the glow of the runes on the walls flickering in rhythm.

It was a high-level defensive rune and defensive magic array.

When the battle is in progress, they provide additional defense to towers and garrisons stationed above.

In addition, there are many firing ports on the castle tower, on which are set up magic cannons and rune giant crossbows.

You must know that this castle tower will not be attacked by the enemy, it is a dragon turtle with thorns,

All enemies who dare to launch an assault will be counterattacked.

As you get closer, the towering walls become even more magnificent.

Especially when it stretches in other directions, there is a feeling of head that you can't see at a glance.

To tell the truth, this is the territory of the Eight Classics that should have city walls!

If Chen Xuan came here in person, he would definitely make such an exclamation in his heart.

Compared to the towering city tower that was 100 meters high, most of the defense lines he had seen seemed insignificant.

At this time, if you zoom out further, you can clearly see that the giant city is the center.

Many roads, large and small, radiate in all directions.

It's like a spoke ring inside a wheel.

There are several main roads that correspond to the entrances to the gates in all directions of the towers.

There were more sergeants stationed there, there were a lot of them, and they were well matched.

There are all kinds of infantry, cavalry, crossbow marksmen, and spellcasters.

In addition, there are quite a few fourth- and fifth-order detection towers.

This type of detection tower can completely penetrate a certain range of stealth targets.

As long as the stealth level does not exceed the level of the detection tower, there is a possibility of being spied on.

If you walk into the city gate at this time and pass through the passage of the city tower more than 30 meters long, you will officially step into the Ataxus giant city.

On the ground in the city, all the main roads are paved with bluestone.

The stone road is not smooth but strong enough to withstand the daily rush of traffic.

And that's just the outermost circle of Atax.

The further you go to the center of the city, the second circle, the first circle, and the core area will pass through one after another!

The buildings on the third floor look similar to Bang City.

It is basically a two- to three-story mixed stone and wood building, with the occasional watchtower.

In addition, there are extremely high stone towers with a height of three or four hundred meters all over the city.

There are at least hundreds of them as far as the eye can see, and they are like pillars stuck in the city.

There are also several cables connecting the different stone towers.

Each cable has a box-like gondola running back and forth.

"Good guys, you actually use cable cars to form the city's public transportation system!"

Not only that, but higher in the sky, there are airships of different sizes.

Some small airships can take off and land directly.

As for large airships, they can only land in special airship ports.

Various types of magic shuttles and vehicles are also common.

Compared to a real giant city, Bangcheng is like a small country town.

This is the real Otherworldly Big City!

There are several cable car towers nearby.

In fact, these cable car towers occupy such a large area that when you get closer, you can see that they are more like a skyscraper.

There is a magic energy hanging basket inside, and the overall structure is similar to an elevator.

If you want to ride the cable car, you must first go to the cable car tower.

Then go up to the cable car platform through the gondola and finally wait for the arrival of the cable car in the designated direction.

These things are designed with the weight of the alien race in mind.

All baskets and cables are reinforced.

With this means of transportation, it can greatly increase the efficiency of traffic in the giant city.

The most important thing is that it is easy to manage.

After all, there are many places in the big city where you can't go by car or horseback.

As for flying, it is even less allowed.

Except for the messengers, the airrider scouts, and those with privileges.

The city of Ataxis is permanently closed to the sky, and any alien flying target that enters it is likely to be shot down by various towers and crossbows.

The height of 100~1200 meters above the ground in the city belongs to the no-fly zone.

Usually, you can only see the airships licensed by the giant city, the magic shuttle, the dragon eagle troops, and a few special air horses roaming.

The rest of any unauthorized projectiles and monsters at this altitude were attacked.

Even the birds that approached the towers were shot down.

Big City has long had an extremely rigorous process in terms of internal defense.

This set of standards has been implemented for thousands of naroa years.

It is said that people become fine when they are old, and if a city is old enough, it can also become fine.

There is basically no problem with the Ataxs Mega City internally.

Even if there were, it has been exposed for thousands of years.

It can be said that the city has withstood the test of time, and many problems have long been solved or optimized.

Therefore, when coming to Ataxus Megacity, most people can only choose to take the cable car or walk obediently.

Either that, or just drive on a limited stretch of road.

However, for many first-time visitors to the Big City, the cable car ride is a novelty experience.

Sitting in the cable car overlooking the city is another style.

The cable car is charged according to the station, and the distance between the two cable car towers generally costs 2~3 crowns.

It's not cheap.

After entering the castle from the third circle, you need to change trains at the cable car tower 8 times to reach the second circle.

It's a bit like Blue Star changing buses.

In other words, if you want to take the cable car to the third level, it will cost you at least twenty or thirty crowns.

There are all kinds of people riding the cable car, and they are always busy and crowded.

But they are like blood vessels that build a new ecology of giant city exchanges.

If you follow the third circle towards the center, you will be able to see the towers of the second circle.

Located on the top of the cable car tower several hundred meters high, you can still see the edge of the wall of the first circle.

It is worth mentioning that the tower on the second floor is actually a little taller and grander than the tower on the third floor.

The accurate data of the height of the castle tower on the third ring is 125 meters ~ 135 meters.

There is a slight difference in the height of different sections of the city.

Some are high, some are lower.

The height of the castle tower on the second circle has reached an astonishing 165 meters ~ 180 meters.

The average thickness has also increased from 35 meters to 50 meters, which is really tall and thick!

Speaking of which, this is a typical layout that is tight on the inside and loose on the outside

This arrangement shows the division of classes within the city.

Ordinary people and poor people lived in the third circle, and rich merchants and petty nobles lived in the second circle.

The great nobles lived on the first level.

As for the ruling class, it must live in the core area.

Maybe there are quite a few estates on the first floor.

The "unpretentious" life of the nobles of the Naroa continent.

Everyone has a luxurious estate.

Compared to the third circle, which occupies the largest area.

The first and second circles are like the true core of the city and where the thriving area is located.

It's also the essence of the big city of Tux.

The third layer is more like the result of years of population growth and expansion.

After all, most of these Terran kingdoms in the Endless Continent today have thousands or even thousands of years of ancient history in Naroa.

In such a situation, the degree of class solidification can be imagined.

And because of the existence of external causes of the invasion of demonic disasters.

Both giant cities and state cities have great defensive potential.

The average start of three city wall defenses is definitely very exaggerated.

In this regard, even state cities such as Magdam are no exception.

The second floor is not only a castle tower, but also a tall and sturdy tower.

Even the sergeants defending the city looked more elite.

The magic arrays and runes arranged are not only more numerous, but also of higher rank.

There are also all kinds of rare equipment for defending the city.

By analogy, the defense level of the towers on the first ring of Atax's giant city is definitely even more terrifying.

However, when the Demonic Plague breaks out, the defense pattern should be adjusted.

The transition from internal defense to external defense is almost inevitable.

Otherwise, the current Ataxus Megacity would not be actively building outlying forts and defensive lines.

Only by blocking the defensive position outside the city can you give full play to the advantages of the defenders as much as possible.

And at this time, the town hall of this magnificent giant city.

A meeting is being convened urgently.
