It was originally a grassy area adjacent to the garden.
But it didn't seem like he was trampled by monsters.
When you look down from a low altitude, you can see the difference between there and the surrounding area.
While the entire manor was trampled into a mess, only that place looked particularly neat and refreshing.
This in itself is an anomaly.
Moreover, there were several curved burn marks on the grass.
It was precisely because of this that it attracted Chen Xuan's attention.
After confirming the target, he controlled the griffon under his crotch to swoop down.
He quickly landed on his destination accurately.
After arriving at the grassland, Chen Xuan did not feel any strange aura.
The magic hidden space, as the name suggests, must have a hidden effect, and it will never be discovered so easily.
He wasn't even sure if he could turn it on.
After getting off the griffin, Chen Xuan walked forward and came to the places with burn marks.
He knelt down and picked up a handful of carbonized grass clippings that were almost burnt bald, with a thoughtful look on his face.
There were a total of six burn marks on the grass, as if there were some high-heat lines releasing heat at a height of about one meter above the ground.
It should be a ritual or the effect of some kind of magic circle.
The problem may not be above ground, it may be underground.
There might have been secret passages or secret rooms in the huge Akso Manor.
The [Grey Flash Altar] will never be placed outside carelessly.
Thinking of this, Chen Xuan looked at his feet.
Activate [Insight] and start looking for clues carefully.
Lines of golden information notes emerged, bringing him a lot of additional information.
When he looked at the burn marks on the grass, he quickly got valuable clues.
[Traces caused by the burning runes projected when the Gray Flash Altar is activated]
...
As expected, those traces are all related to the Gray Flash Altar.
Turning off [Insight], Chen Xuan slowly closed his eyes.
The ability to sense space makes everything around you appear in the form of points, lines and planes in your mental vision.
Except for the Baron's Castle, the Mage Association, the Library and other areas where there is interference from the magic circle.
Most of the first circle was covered by his spatial perception ability.
Including the huge Akso Manor is no exception.
There are three blind spots in the manor.
There are two places right below the main manor, and they are probably secret rooms or something like that.
There is another one just below this lawn clearing.
The existence of a blind spot means that there is some kind of interference in the space there.
In other words, the places that cannot be explored are often the places where there are problems.
The space sensing blind spot under the lawn is most likely where the [Gray Flash Altar] is hidden.
Looking at the spatial location map, the specific location should be more than 100 meters underground.
If we use brute force to reach such a deep layer, it will take at least several water clock hours.
So we still have to find the most convenient way to enter through the entrance passage.
Under the spatial induction, nothing can be evaded.
Ordinary spatial areas will become clear flat and vertical images in the mind.
And those areas hidden in magic interference will become extremely eye-catching blind spots.
As long as you see the blind spots, you will know where the problem is.
As for the passages extending in all directions, they are difficult to be completely covered by interference, and they are extremely conspicuous in the three-dimensional drawing of spatial sensing.
As long as you find the passages corresponding to the blind spots, you can quickly follow the clues to find the entrance.
Under such circumstances, Chen Xuan quickly locked the location of the entrance to the passage.
There is a secret room at the foot that is suspected to contain the main node of the [Grey Flash Altar]. The entrance to the passage is by the fountain two to three hundred meters away.
After confirming the exact location, he walked towards the location of the fountain in the manor.
There is a small circular pond about thirty meters in diameter.
In the pond stands a statue of a goddess holding a showerhead in a watering state.
A fountain gushes out from the shower head, splashing into the landscaped pond, creating ripples.
There was a serious stampede here.
The head of the statue was missing, and there were several eye-catching impact marks on its slim body.
Black and red dirt floated on the water, exuding a pungent smell.
Wherever the monster passes, it will inevitably become a mess.
The entrance to the passage is on the square base under the statue.
Chen Xuan conveniently cast a [Levitation Technique] on himself.
Surrounded by light cyan wind spirit elements, he floated up as light as a swallow and flew towards the statue.
Landing on the base 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 and lifted 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 monsters to pass through, and it is a bit cramped even for humans.
This should be the passage secretly built by Ansetus while he was lurking in the city.
After all, as long as the [Gray Flash Altar] is formed, it can cross the stratum and drop the monsters directly on the ground, without having to let the monsters return to the ground through the passage.
That secret room is just a place where the ritual altar is hidden. It does not hinder the final delivery result.
As soon as I pried open the stone slab, I was greeted by the smell of dust.
It can be seen that no one has passed through this passage for some time.
Chen Xuan frowned and began to chant and cast spells.
The spell representing the Gust of Wind technique quickly took shape under the outline of powerful mental power.
The free magic power gathered together to materialize the spell model.
When the runes shimmered and dissipated.
Instead, there were gusts of air blowing into the passage.
With Chen Xuan's attainments as a third-level spell caster.
It only takes less than two seconds to cast this second-level spell.
The air flow poured into the channel, and large amounts of dust were kicked up.
At the same time, it also brings fresh air to the passage that has not been opened for a long time.
When the gust of wind subsided and the dust settled, Chen Xuan took out the searchlight and walked down the stairs in the passage step by step.
The long passage is unremarkable.
The construction is not beautiful, and even a little perfunctory.
The walls on all four sides are made of stone and have been extensively solidified with first-order runes.
This further proved Chen Xuan's guess.
That is, this passage should have been built by Ansetus after he was controlled by the Black Demon Dragon Baile.
Go along the passage, sometimes turning, sometimes going down.
After advancing for more than ten minutes, we finally reached our destination.
At the end of the passage is a closed hall.
There is a thick rune door that isolates the inside and outside of the hall.
The entire hall is integrated, like a black square box.
Not only can it isolate the effect of spatial perception, but even Chen Xuan's third-level mental power cannot penetrate it.
Even though the passage Ansetus built was very perfunctory, the secret room he built was still water-free.
After Chen Xuan approached, he raised the [Thunder Surge] sword in his hand and poked the rune door with the tip of the sword, but no trace was left.
The secret room hall in front of you was completely built according to the standards of fortifications.
Then he input some gold-level magic elements into the sword in his hand.
"Hiss!"
A blue lightning arc suddenly appeared on the straight sword.
Even the sword trembled slightly and even made a low buzzing sound.
It seems a bit overloaded.
After all, it is just a third-level magic weapon. It is stimulated with gold-level magic. It is normal for the reaction to be large.
Chen Xuan's wrist shook slightly, and the [Thunder Surge] sword struck towards the rune gate.
"Qiang!"
"Zhila!"
The sound of the collision of gold and iron came first.
A sunken gap suddenly appeared on the surface of the gray-black rune door.
Thunder arcs shot out in all directions, and the air was filled with the smell of anxiety.
The defensive power of this rune door is good. The gap created by Chen Xuan is about two fingers deep. It looks okay, but in fact it is somewhat unsatisfactory.
You must know that he is now a gold-level powerhouse. Although his physical transformation has not yet been completed, the blessing of gold-level magic is not fake.
But even so, it can only create a small gap.
Breaking through the defense is not a problem, but it is not easy to penetrate the rune door in front of you.
God knows how thick this door is.
Putting away the [Thunder Surge] battle sword, Chen Xuan slowly stepped back.
After retreating a hundred meters away, he stopped and took out a Red Arrow 12E anti-tank missile launcher from the storage compartment.
After taking direct aim at the rune door, he pressed the launch button.
Now that we already know the defensive power of the rune gate, there is no need to stupidly chop it with a war sword.
Just use anti-tank missiles.
As an armor-piercing weapon aimed at heavy vehicles, its lethality is mainly reflected in the metal jet.
The passage reinforced with low-level runes should be able to withstand the shock wave that escapes around during the explosion.
The end cover of the Hongjian 12E anti-tank missile launched by ignition bounced off.
Small boosters ejected huge streams of flames.
The flames illuminated the passage in an instant.
The hot exhaust swept backwards, raising dust on the ground.
"Phew!"
Chen Xuan's body didn't even sway, and he steadily put down the transmitter in his hand.
"Boom!"
A distance of one hundred meters is nothing for an anti-tank missile.
Almost instantly.
When the missile accurately hits the rune door.
The front warhead was detonated first, and then the metal medicine cover installed on the front was melted by the high temperature, forming a flow of liquid metal that shot towards the surface of the rune door.
Huge explosion shock waves swept everywhere.
The stone wall of Rune Gate shook violently, but fortunately it did not collapse.
The straight passage at the rear has become the best outlet for shock waves and flames and smoke.
They were wrapped together and swept along the passage in a mighty manner.
Chen Xuan, who was standing in the passage, calmly raised his hand, and the next moment he took out a 600mm × 1750mm super large level IV bulletproof shield.
Holding the shield with one arm, he turned slightly sideways to resist the impact.
The narrow passage appeared like a wind tunnel effect under the shock wave.
The instantaneous airflow with extremely strong wind speed carried high temperature and flying metal fragments, and hit hard in front of Chen Xuan, who was defending with a shield.
"Bang!"
The huge impact made Chen Xuan take a few steps back.
The combat boots made of bronze rubbed violently on the stone floor, and even splashed out eye-catching sparks.
It's like a turbid current meets a rock, and the mighty shock wave is contained here.
The airflow and metal fragments hit the shield surface, making a crisp sound.
Then it rolls back toward the top of the channel.
It wasn't until a few seconds later that the restless airflow gradually calmed down.
The flames quickly consumed the oxygen in the channel, and the high temperature made the ground dry instantly.
Putting away the shield, he couldn't help but be a little surprised when he saw that the bulletproof surface that had withstood the impact became pitted and covered with scorch.
Using a bulletproof shield to resist the shock wave after the explosion of an anti-tank missile was something he had never dared to think about before.
Even if the shield could block the shock wave and metal fragments, the huge impact was enough to knock him directly to the other end of the passage.
The instantaneous impact was terrifying.
Even ordinary silver-level experts might not be able to stop him.
Put away your shield and hold your breath.
The dust at the end of the passage quickly cleared.
There was a small ball of flame burning on the ground next to it.
The fragments of the escaping projectile hit the walls on both sides with craters.
The most eye-catching thing was the rune door that was hit head-on.
There is a crater with a diameter of about 40 centimeters at the location where the Red Arrow 12E was hit.
This pit is funnel-shaped, wide at the top and narrow at the bottom.
The penetration depth is about seventy or eighty centimeters.
Only at the end position, the penetration hole diameter is only one or two centimeters.
You must know that the homogeneous steel armor-piercing power of the warhead of the Red Arrow 12E reaches 1000 mm.
After comparison, it can be found that the defensive performance of this rune door is stronger than the homogeneous steel in 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 Blue Star's main battle tank?
It does not represent the thickness of its armor.
For example, some tanks use polymer armor, but the actual thickness is only two to three hundred millimeters.
If replaced by homogeneous steel, the equivalent defense would be eight to nine hundred millimeters.
This does not mean that the polymer armor itself is eight or nine hundred millimeters thick, it is just a reference standard.
From this point of view, the rune door in front of me is really a stone in a pit -
smelly and hard.
Chen Xuan frowned and turned back into the passage, intending to shoot the Rune Gate one or two more times.
No matter how thick this thing is, there is a limit.
Boom and that's it.
...
More than ten minutes later, Chen Xuan wiped the sweat from his forehead while looking at the big hole in the rune that he could bend through.
There is no doubt that Ansetus spent a lot of money building this secret chamber hall!
The rune gate in front of him and the walls in the secret room are made of multiple layers of bronze, dark gold, and precision forged alloys that are alternately cast.
The overall thickness reaches more than two meters.
The cost of materials alone is as high as two to three million crowns.
This is the defense power accumulated purely by stacking materials.
The hall is very empty and simple, with no unnecessary furnishings or items.
Here Chen Xuan finally saw the main node of the [Grey Flash Altar].
He walked to the altar, intending to find the location of the hidden magic space.
I launched [Insight] as usual, and prompt text appeared soon.
[The main node of the Gray Flash Altar]
[The magic hidden space attached to it is slowly collapsing]
...
Chen Xuan felt bad when he saw these two lines of information.
But soon, a new prompt appeared!
