It was originally a meadow adjacent to the garden.

But it doesn't seem to be trampled on by monsters.

When you look down from a low altitude, you can see the difference between it and the surrounding area.

When the whole estate was trampled into a mess, only it looked exceptionally neat and fresh.

This in itself is an anomaly.

And on that meadow, there are still a few crooked burn marks,

It was precisely because of this that Chen Xuan's attention was aroused.

Once he had settled on his target a little, he controlled the griffin under his crotch and swooped down.

Soon it landed on the destination with precision.

After coming to that meadow, Chen Xuan didn't feel any unusual aura.

The Hidden Space, as the name suggests, definitely has a hidden effect, and it will never be so easy to find.

He wasn't even sure if he could turn it on.

Turning over and getting off the griffin, Chen Xuan paced forward and came to the places where there were burn marks.

Squatting down and picking up a handful of carbonized grass clippings that were almost burned bald, he looked thoughtful.

There were a total of six burn marks on the grass, as if some hot lines were releasing heat at a height of about a meter above the ground.

It should be a ritual or the effect of some kind of circle.

The problem is not necessarily on the ground, it may be underground.

It is possible that the vast Axel Manor would have had a secret passage or a secret room or something like that.

The [Gray Flash Altar] will never be placed outside with a big grin.

Thinking of this, Chen Xuan looked at his feet.

[Insight] is activated, and you will begin to carefully search for clues.

Rows of golden message notes appeared, bringing him a lot of additional information.

As he looked at the burn marks on the grass, he quickly got a valuable clue.

[Traces formed by the burning of runes cast when the Grey Flash Altar is activated]

……

Sure enough, those few traces were related to the Ash Flash Altar.

Closing [Insight], Chen Xuan slowly closed his eyes.

The ability to sense space makes everything around you appear in the form of dots, lines, and planes in the form of mental vision.

Except for the Baron's Castle, the Mage Guild, the Library, and other areas where there is interference with magic arrays.

Most of the first circle was enveloped by his spatial perception.

Including the huge Akso Manor is no exception.

There are three blind spots in the estate.

Two of them are directly below the main manor, and I guess they must be secret rooms or something.

There is another one just below the lawn clearing.

The presence of blind spots means that there is some kind of interference in the space.

In other words, what can't be explored is often the place where there is a problem.

And this space-sensing blind spot under the lawn is likely to be the hidden location of the [Gray Foil Altar].

Looking at the spatial location map, the specific point should be more than 100 meters underground.

If brute force were to be used in such deep formations, it would have to be delayed for at least several hours.

So you still have to find a way to enter through the entrance passage is the most convenient.

Under the sense of space, nothing can be hidden.

Ordinary areas of space will be turned into clear flat vertical drawings will appear in the mind.

Areas that are hidden in the magic will become conspicuous blind spots.

Just by looking at the blind spots, you can know exactly what is wrong.

As for the passage in all directions, it is difficult to be completely covered by interference, and it is extremely conspicuous in the spatial sensing vertical drawing.

As long as you find those passages corresponding to the location of the blind spot, you can quickly find the entrance.

Under such circumstances, Chen Xuan quickly locked the location of the entrance to the passage.

The secret room that seems to be hiding the main node of the [Gray Flash Altar] at the foot, and the entrance to the passage is next to the fountain two or three hundred meters away.

Once he had confirmed the exact location, he walked to the location of the fountain in the manor.

There is a small circular pond with a diameter of about 30 meters.

Inside the pond stands a statue of a goddess holding a shower in her hand.

A fountain gushes out of the shower, sprinkled in this landscape pond, rippling a ripple.

There was a serious stampede here.

The statue's head was missing, and there were several striking strikingly impact marks on the slender body.

The surface of the water was filled with black and red dirt, giving off a pungent smell.

Wherever the monsters go, it will inevitably become a mess.

And the entrance to the passage is on a square pedestal under the statue.

Chen Xuan casually performed a [Levitation Technique] on himself.

Surrounded by pale cyan wind spirit elements, his body as light as a swallow fluttered up and flew towards the statue.

Landing on the pedestal of the stone platform, Chen Xuan quickly found the entrance to the passage.

The entrance was covered by two large stone slabs, and no protective magic circle was applied.

He took out the [Thunder Surge] sword and pried it along the edge to open the entrance.

It is a square passage with a length and width of about 2 meters.

It is not suitable for strange-shaped monsters, and even for humans, it is a bit cramped and cramped.

This is supposed to be a passage that Ansetus secretly built while he was lurking in the city.

After all, as long as the [Gray Flash Altar] is formed, it can cross the ground and drop the monster directly on the ground, without the need to let the monster return to the ground through the passage.

The chamber was nothing more than a place to hide a ritual altar. It does not hinder the final delivery result.

As soon as I pried open the slate, I was greeted by a smell of dust.

It can be seen that this passage should have been unattended for some time.

Chen Xuan frowned and began to chant and cast spells.

The spell representing the gust of wind quickly took shape under the outline of the powerful spiritual power.

The discrete magic converges to make the spell model material.

When the runes shone and the light dissipated.

Instead, gusts of wind blew into the passage.

With Chen Xuan's attainments as a third-order spellcaster.

It also takes less than two seconds to complete this second-order spell before and after casting.

The air flow is poured into the tunnel, and large clouds of dust are kicked up.

At the same time, it also brings fresh air to the passage that has not been opened for a long time.

Only when the gusts of wind subsided and the dust settled, did Chen Xuan take out the searchlight and walk down the steps in the passage step by step.

The long passages have no bright spots.

The construction is not beautiful, and even a little perfunctory.

The walls on all four sides were made of stone, and they had been solidified over a large area of first-order runes.

This further proves Chen Xuan's guess.

That is, this passage should have been built by Ansetus after it was controlled by the Dark Dragon Belle.

Follow the passage, sometimes turning, sometimes down.

It took more than ten minutes to finally reach the destination.

At the end of the passage is an enclosed hall.

A heavy runic door separated the inside and outside of the hall.

The whole hall was integrated, like a black box.

Not only could it isolate the effect of spatial perception, but even Chen Xuan's third-order spiritual power could not penetrate it.

Don't look at the passage built by Ansetus is very perfunctory, but the secret room he built is still not mixed with any water.

After Chen Xuan approached, he raised the [Thunder Yong] battle sword in his hand and poked the rune door with the tip of the sword, leaving no trace.

The hall of the chamber in front of you was built entirely to the standards of fortifications.

Then he injected some gold-level magic essence into the battle sword in his hand.

"Shhhh

I saw that the straight sword body suddenly swirled with a blue arc of thunder.

Even the sword body trembled slightly, and even let out a low beep.

It looks like it's overloaded.

After all, it's just a third-order magic weapon, and it's normal to have a large reaction when it is stimulated by a gold-level magic element.

Chen Xuan's wrist shook slightly, and the [Thunder Surge] battle sword slashed towards the rune gate.

"Boom!"

"Zila!"

First, the sound of the collision of gold and iron came.

A depression suddenly appeared on the surface of the gray-black rune door.

The arcs of thunder shot out in all directions, and the air was filled with the smell of scorching.

The defense of this rune door is good, and the gap that Chen Xuan has cut is about two fingers deep, which looks okay, but in fact it is a little unsatisfactory.

You must know that he is now a gold-level powerhouse, although the physical transformation has not yet been completed, but the blessing of the gold-level magic element is not fake.

But even then, it can only make a small gap.

It's not a problem to break the defense, but it's not easy to chisel through the rune door in front of you.

God knows how thick this door really is.

Putting away the [Thunder Surge] battle sword, Chen Xuan slowly stepped back.

After retreating to a distance of 100 meters, he stopped and took out a Red Arrow 12E anti-tank missile launcher from the storage compartment.

After aiming directly at the rune door, he pressed the launch button.

Now that you know the defensive power of the Rune Gate, there is no need to stupidly slash with your sword.

Just go directly to the anti-tank missile.

As an armor-piercing weapon for heavy vehicles, its lethality is mainly reflected in metal jets.

And the passage reinforced by low-level runes should be able to withstand the shock wave that escapes to the surrounding area during the explosion.

The end cover of the Red Arrow 12E anti-tank missile launched by ignition bounced off.

Small boosters shoot out raging flames.

In the blink of an eye, the flames illuminated the passage.

The scorching exhaust swept backwards, kicking up dust on the ground.

"Whew!"

Chen Xuan's body didn't even shake, and he steadily put down the transmitter in his hand.

"Boom!"

A distance of 100 meters is not worth mentioning for an anti-tank missile.

It's almost instantaneous.

When the missile hits the rune gate accurately.

The front warhead was the first to detonate, and then the metal pill cover mounted on the front end was melted at high temperatures, forming a stream of liquid metal that shot at the surface of the rune door.

A huge blast blast wave swept in all directions.

The stone wall of the Rune Gate shook violently, but fortunately it did not collapse.

The in-line tunnel at the rear became the perfect outlet for shock waves and flames.

They were wrapped together, swept along the passage.

Chen Xuan, who was standing in the passage, raised his hand unhurriedly, and the next moment he took out a 600mm×1750mm super-large level IV bulletproof shield.

Holding a shield with one arm, he made a gesture of resisting the impact slightly sideways.

The cramped passage has a wind tunnel effect under the infusion of shock waves.

In an instant, the extremely strong wind current, wrapped in the high temperature and splashing metal fragments, slammed into Chen Xuan, who was defending with a shield.

"Bang!"

The huge impact force made Chen Xuan take a few steps back.

The bronze boots rubbed against the stone floor, and even burst into striking sparks.

It was as if the turbidity current had hit a reef, and the shock wave was contained here.

The air flow and metal fragments collided against the shield with a "clanging" sound.

Then it rolls back to the top of the channel.

It wasn't until a few seconds later that the agitated air flow subsided.

The flames quickly consumed the oxygen in the tunnel, and the heat made the ground dry in an instant.

I put away my shield and watched the bulletproof surface that had been subjected to the impact become pitted and scorched, and I couldn't help but be a little surprised.

Using a bulletproof shield to resist the shock wave after the explosion of an anti-tank missile, such a thing he would not have dared to think of before.

Even if the shield could block the shockwave and metal fragments, the impact was powerful enough to slam him directly at the other side of the tunnel.

The instantaneous impact is terrifying.

Ordinary silver-level powerhouses may not be able to stop it.

Put away your shield and hold your breath.

The dust at the end of the passage quickly cleared.

There was also a small flame burning on the ground next to it.

The fragments of the escaped projectile hit the walls on both sides of the potholes.

The most eye-catching thing was the rune door that was hit head-on.

The location of the Red Arrow 12E blow had a crater about forty centimeters in diameter.

This pit is funnel-shaped, wide at the top and narrow at the bottom.

The depth of the wear is about seventy or eighty centimeters.

It's just that at the end, the penetration aperture is only a centimeter or two.

You must know that the homogeneous steel armor-piercing power of the warhead of the Red Arrow 12E reached 1000 mm.

After comparison, it can be found that the defensive performance of this rune gate is stronger than the homogeneous steel in the blue star.

Of course, homogeneous steel is just a concept used to measure equivalent armor.

In fact, how many millimeters is the so-called defense coefficient of the main battle tank of the Blue Star.

It does not represent the thickness of its armor.

For example, some tanks use polymeric armor, and the actual thickness is only two or three hundred millimeters.

Replaced with homogeneous steel, it can reach eight or nine hundred millimeters of defense.

This does not mean that the aggregate armor itself is eight or nine hundred millimeters thick, but only a reference standard.

From this point of view, the rune door in front of me is really a stone in a pit-

- Stinky and hard.

Chen Xuan frowned, turned around and retreated into the passage, intending to give the rune door one or two more shots.

There's a limit to how thick this thing is.

Boom and that's it.

……

More than ten minutes later, Chen Xuan looked at the big hole in the rune that he could bend through and wiped the sweat from his forehead.

Needless to say, Ansetus definitely paid a lot of money to build this Chamber of Secrets!

The rune gate in front of him and the walls in the chamber were made of alternating layers of bronze, dark gold, and fine-wrought alloys.

The overall thickness reaches more than two meters.

The cost of materials alone can be as high as two to three million crowns.

This is a defense that is purely based on the accumulation of stockpiles.

The hall is empty and simple, with no superfluous furnishings and items.

Here, Chen Xuan finally saw the main node of the [Gray Flash Altar].

He walked over to the altar, intending to find the location of the Hidden Space.

[Insight] was launched as usual, and soon a prompt text appeared.

【Main Node of the Grey Foil Altar】

[The hidden space attached to it is slowly shrinking]

……

Seeing these two lines of information, Chen Xuan suddenly felt bad.

But soon, new hints appeared!

…… (End of chapter)
