Starting from the small town Northwest Military Region, follow the mountains to the northwest and fly over the wilderness.
In the first half, you can still see scattered villages and towns and patrolled military outposts, but in the second half, there is nothing.
The green on the ground faded away little by little, and in the end all that was left was weathered rock.
Lin Feng was sitting cross-legged on the dragon's back, and the flow of energy and blood in his body was obviously slower than when he was in the capital.
The communicator signal is also getting weaker and weaker.
After flying about two hundred kilometers further, Earth Dragon's speed slowed down.
Not tired.
It is hesitating.
The dragon's head moved left and right twice, and a low buzzing sound came from its throat.
This kind of sound Lin Feng only heard it once in the Hundred Thousand Mountains Core Zone, Earth Dragon's instinctive reaction when faced with Dragon Vein.
There is something underground ahead.
Lin Feng's mental power is going down.
Passing through the weathered rock formations, through the gravel belt, and about three hundred meters down, there is a pulse of energy.
The frequency is very slow, about once every four or five seconds.
Like something breathing deep underground.
Lin Feng Take out Jade Tablet from Storage Ring and check the coordinates again.
Arrived.
"Fall."
Earth Dragon folded its wings and dived, stepping on the wasteland ground with its four claws, crushing a layer of weathered rock.
Lin Feng jumped off the dragon's back and scanned around.
There are no landmarks within a few kilometers, just a flat wasteland.
The coordinates on Jade Tablet point to a location thirty meters north of your feet.
Lin Feng walked over.
The weathered rocks under your feet are no different from anywhere else.
It's hard when you step on it, and the surface is covered with a layer of fine sand.
Exploring mental strength.
At a depth of thirty meters, the energy pulsation becomes more obvious.
But no traces can be seen on the surface.
Lin Feng raised his foot and stomped it down.
Qi and blood are poured into the soles of the feet, and the power of the second stage of Martial Saint is fully output.
Boom!
All the weathered rocks within a radius of ten meters below the feet were shattered, and the gravel was scattered everywhere.
Expose the stone slab below.
The surface is densely engraved with Array Pattern.
The lines have been filled with sand and soil, and you can't even see them unless you look carefully.
Lin Feng squatted down and used his hands to remove part of the sand on Array Pattern.
The direction of Array Pattern is spiral, converging from the periphery to the center.
There is a fist-sized groove embedded in the center.
The shape is exactly the same as the bottom of Jade Tablet.
Lin Feng pressed Jade Tablet in.
No response.
He tried again and pressed down.
Still no response.
Jade Tablet is embedded in the groove and does not move at all, and Array Pattern does not light up either.
Lin Feng took out the military license and read the instructions above.
"Secret Realm entrance activation method: Qi and blood infusion + Psychic Power double unlocking. It requires Martial Saint level or above to trigger."
He took the license back.
Press your left hand on Jade Tablet, and Qi and blood will gush out from your palm and pour into Array Pattern along Jade Tablet.
At the same time, the spiritual power is pushed out from the center of the eyebrows and penetrates into the lines of Array Pattern.
Buzz!
Array Pattern is on.
The dark golden light starts from the outer spiral pattern and runs towards the center in circles. Every time it lights up, the ground shakes.
The whole process lasted half a minute.
When Array Pattern in the innermost circle also lights up, the stone slab underfoot begins to move.
The entire stone slab sank two meters, revealing a stone door.
The stone gate is three meters high and two meters wide.
The door frame is engraved with the same Array Pattern as the ground, but the door panel itself is smooth.
The material is not like stone, but rather like some kind of metal, with a faint dark light on the surface.
There was a crack in the middle of the stone door from top to bottom.
The seam is getting wider and wider.
The door opened.
Inside is a stone staircase passage extending downward.
You can't see the bottom, it's so dark.
But something came out of it.
An air that cannot be described as smelly.
Lin Feng took a sip.
This smell was familiar to him.
This is the taste after a large amount of blood is oxygenated.
But the smell is too strong.
Earth Dragon took two steps back.
Lin Feng looked back at it.
The stone gate is only two meters wide and three meters high.
The size of Earth Dragon cannot fit inside.
"Stay outside and don't run around. If something comes close, yell."
Earth Dragon's dragon head clicked.
Lin Feng glanced at the sky again.
Fierce Vulture is hovering high in the sky.
"Come down low and guard this entrance."
Fierce Vulture retracted half of its wings and dropped to about ten meters in height.
It's arranged.
Lin Feng turned around and faced the stone door.
Crimson Gold Spear cannot be used, the cracks on the barrel have not been repaired.
He took out the remaining twenty-four Starfall Nine-Tribulation Blade from Storage Ring, divided them into two groups and hid them in his sleeves.
Indestructible Golden Body operates, and golden lines float on the surface of the skin.
Step into the stone gate.
When I stepped on the first stone step, the stone door behind me began to close.
Lin Feng didn't look back.
I thought about this situation before I came in.
S-Rank Secret Realm is not open to wasteland. The entrance is closed after entering, which is normal.
The military's documentation didn't mention this, probably because they haven't been there themselves and don't have data.
The sound of the stone door closing sounded behind me for three seconds and then disappeared.
The light also disappeared.
It was completely dark in the passage.
But Eye of Ten Thousand Beasts of Lin Feng does not need light.
The vertical pupil lit up in his left eye, and everything in the darkness became clear.
The stone steps are cyan, the height and width of each step are exactly the same, and they are cut very regularly.
The walls on both sides are also engraved with Array Pattern, but these Array Pattern have been extinguished and no aura remains.
The inclination angle of the passage is about thirty degrees, going all the way down.
Lin Feng Go down.
I counted more than 400 steps.
A rough estimate shows that the vertical depth has exceeded one hundred meters.
The strange smell in the air is getting stronger and stronger.
At the 450th step, the width of the passage suddenly expanded.
From two meters to ten meters.
The stone steps also disappeared and turned into flat ground.
Lin Feng's feet stepped on the ground and paused for a moment.
Push forward mentally.
I pushed for fifty meters and didn't hit the wall.
After pushing for a hundred meters, I still haven't hit the wall.
When I pushed to two hundred meters, I hit something.
The feedback from his mental power told him that there were densely packed skeletons on the ground two hundred meters ahead.
There are humans and there are beasts.
The size difference is huge.
The smallest is only one meter, the largest...
My mental energy followed the outline of the bone.
One rib alone is more than twenty meters long.
What kind of beast can grow so big?
Lin Feng Go forward.
After walking fifty steps, I stepped on something hard.
When he looked down, he saw that it was a broken sword.
Only half of the sword's blade is left, and the metal at the fracture has been oxidized to dark brown.
But the inscriptions carved on the hilt of the sword are still vaguely legible.
Ancient seal script.
Lin Feng recognizes a few words.
"Eternal Suppression".
The words on the back are so corroded that they can't be read clearly.
He ignored the broken sword and continued to move forward.
There are more and more debris on the ground.
Broken swords, broken armor, bones, and teeth were mixed together to form a layer.
It rattles when you walk on it.
There was a war in this place.
A long time ago.
Beaten very badly.
After walking two hundred meters, the pile of giant skeletons appeared in sight.
Lin Feng looks up.
Eye of Ten Thousand Beasts glanced upward along the outline of the bones.
A huge skull is half buried in the rubble, the mandible has fallen off, and each tooth is thicker than Lin Feng's arm.
There are two eye sockets above the skull.
Empty and black.
The mental power swept across the surface of the skull, leaving an extremely weak breath of Dragon Vein.
Dragon.
This is the corpse of a dragon.
I don't know how many years have passed since my death.
Lin Feng Go around the keel and continue walking inside.
There is another one behind the keel.
The second body. The third body. The fourth body.
He kept walking and counting.
After walking about 500 meters, I counted eleven keels.
They vary in size, but each one is several times larger than his Earth Dragon.
In addition to the keel, there are other Giant Beast bones scattered everywhere.
Some of them he could tell their species based on their bone structure, but there were more that he couldn't identify.
The bottom floor of this Secret Realm is the ruins of a battlefield.
The battlefield of dragons and beasts.
The passage continues to extend deeper.
The flat ground disappeared and was replaced by an uneven patch of broken rock.
There are cracks between the broken rocks, and a dark red light shines from deep in the cracks.
The light source is unknown.
Lin Feng squatted down and took a look into the crack.
There is liquid flowing under the crack, which is about ten meters deep.
A viscous, slow-flowing liquid.
The area is not large, and visually it is just a narrow ditch.
But the temperature is very high, and hot air rises from the cracks.
He mentally probed the liquid.
The blood concentration is extremely high.
The blood concentration in this blood was several times higher than the Dragon Vein Essence Blood he drew from Bai Yong's body.
Lin Feng stood up and looked around.
The area of Broken Rock Zone is about several hundred square meters, with cracks crisscrossing it.
There is dark red liquid flowing under almost every crack.
S-Rank Unopened land Secret Realm.
The military does not have preliminary exploration data.
Now he understands why it is S-Rank.
The value of the blood in these cracks alone is immeasurable.
If it can be extracted, it will be of immeasurable help to cultivation.
Huh?
Lin Feng's eyes suddenly focused forward.
At the end of Broken Rock Zone, about three hundred meters away, there is a huge shadow.
The shadows are moving.
Slow, rhythmic rise and fall.
Breathe.
There are living things.
Immediately afterwards, a deep beast roar came from three hundred meters away.
