In the dark stone path, Nie Tian followed the fire light released by the Yanlong Armor and headed straight towards the ground.

There was no need to perceive it with spiritual consciousness, there was always a vague connection between him and the blood core in the Yanlong armor.

Even without the fire emitted by the Flame Dragon Armor, with the induction between him and the blood core alone, he could accurately find the direction and go straight underground.

The stone path opened up by the refiners of the Spirit Treasure Pavilion was unfathomable, and Nie Tian went all the way down, and he didn't know how many distances he had traveled, and suddenly stopped.

His stop was not due to his own reasons, but because of the Yanlong armor...... It has sunk to the end.

At the end of the stone path, which can only accommodate the two of them, there are fragmentary traces of mining.

The flame dragon armor embedded in the blood core unleashed a surging flame, and suddenly slammed into the end of the stone path.

"Click!

The hard stone walls were shattered one after another, and the Yanlong armor seemed to turn into a sharp drill bit, constantly chiseling down on the endless stone wall.

Nie Tian saw that the Yanlong Armor used this method to forcibly open a new stone path leading to the underground.

He didn't know what was going on, but he knew that at this moment, letting the Yanlong Armor go alone and wasting too much time here would be extremely detrimental to his safety.

"Flame Dragon Armor, Blood Core ......"

He shouted again and again in his heart, hoping to be like the beginning, and the Yanlong Armor could hear his heart and return to the storage bracelet.

He knew that in the stone cave when he came, others might not want to wait, or they might leave him, but An Shiyi ...... Because of their gratitude to him, they will stay where they are and wait for him.

Waiting for too long is easy to be captured by the powerhouses of the Blood Sect and the Ghost Sect, which may put An Shiyi who is left in trouble.

He only hoped that the Yanlong Armor would respond to him, that he could stop his exploration of the underground, and return with him as soon as possible.

It's a pity that the Yanlong armor and the blood core didn't seem to hear his call, and they were still trying their best to chisel through the stone wall leading to the earth, and continued to dive down.

He was helpless, knowing that staying here would only increase the crisis, but he couldn't give up the Yanlong armor, so he could only passively follow and dive into the depths of the earth.

"Click!"

A large amount of gravel has been chiseled out by the Yanlong armor, and the stone path behind it will soon be congested.

Nie Tian often flashed in quickly before the stone path was blocked, keeping a distance of several meters from the Yanlong Armor, and continued to descend.

That strange flame dragon armor, I don't know what went crazy, burst out with amazing power, like a sharp cone, madly stabbed the earth.

Nie Tian followed in fear, feeling that he was getting farther and farther away from the surface, and his heart was becoming more and more uneasy.

"Boom!"

I don't know how long it took, and a loud bang burst from the stone that the Yanlong armor impacted.

In the depths of the earth, as if a huge mouth was deeply chiseled by the Yanlong Armor, the Yanlong Armor stayed in the huge mouth, as if he was hesitating about something.

Nie Tian noticed that from inside the huge mouth, there was a strange "gurgling" sound, and red smoke rose up.

The smoke, with a hint of sulfur, seemed to come from the magma juice underground.

"What's the situation?" he slowly leaned in and looked intently, his face changing suddenly.

He saw that under the huge mouth where the Yanlong armor was staying, there was blazing magma, and those magma were surging, emitting huge flame bubbles and steaming red smoke.

"The magma in the center of the earth can be ...... Shouldn't this be an extinct volcano?" Nie Tian was stunned.

According to Pan Tao's statement, the Chiyan Mountains were full of volcanoes spewing flames very early ago, but time has passed, and now there are only three volcanoes in the Chiyan Mountains near the Lingbao Pavilion.

Those three volcanoes were also exquisitely controlled by the Spirit Treasure Pavilion's "Earth Fire Burning Heaven" array, and they would never erupt blazing earth flames.

The flames in the center of the earth under the three volcanoes were pulled by the formation and were guided to the refining rooms one by one, and the refining room of the Treasure Pavilion was used to refine the spiritual weapons.

Once the Lingbao Pavilion encounters a great change and opens the "Earth Fire Burning the Sky" Great Array, it will pull out the Earth's Core Flame and turn into the source of the power of the Great Array.

In addition, the other peaks of the Chiyan Mountains are extinct volcanoes that have been silent for an unknown number of years.

The fire in the center of the earth under those extinct volcanoes has long since disappeared completely, and there is nothing left.

But at the bottom of this low mountain, which Pan Tao pointed out as an extinct volcano, the Yanlong armor continued to chisel down, and when he chiseled to the end, he clearly saw that what was flowing under the giant mouth was blazing magma and fire water!

"Flame Dragon Armor, are you here for the flaming water in the center of the earth?" his mind moved, and he suddenly came to his senses.

The blood core requires a huge flame power to condense blood, and the formation of a drop of blood has many wonderful uses.

In the Nie family's mine, all the fire marble stones were sucked dry of the power of the flames, and they only helped the blood core to condense a drop of blood.

And that drop of blood, when it brought him out and into a mysterious place, seemed to consume a huge amount of power, and shrunk several times.

Now, the blood core and the flame dragon armor are one, and it seems that there is an urgent need for more surging flame power, and those magma flames from the center of the earth here seem to be the flame power required by the flame dragon armor.

It's just that the Yanlong armor has clearly chiseled through layers of thick stone walls, and finally arrived here, why does it seem a little hesitant?

When he was puzzled, he suddenly saw that the Yanlong Armor was releasing monstrous flames, and suddenly fell towards the magma fire water under the giant mouth.

But, at this moment, a mutation protruded!

Those hot and turbulent magma and fire liquids that seemed to be able to instantly turn any living creature into blood and water, a thin layer of space on the surface, instantly appeared with crystalline ribbons.

The ribbons seem to be made of jade and crystals, soft and long.

Countless crystal-like ribbons, intertwined, like a magnificent giant net, covered the surface of those magma and fire liquids.

Nie Tian only glanced at it, and found that those crystal-shaped ribbons were like veins in flesh and blood, and there were many exquisite runes flowing in the ribbons.

Those runes were of different colors, some like leaves, some like stars, and some like wriggling beasts.

"The refiner of the primeval era, the ancient talisman that communicates the power of heaven and earth!" Nie Tian was shocked.

During this time, he followed Wu Lone, heard a lot of things about the ancient qi refiners, and also knew a little bit of the subtlety of the ancient runes, and he was still trying to learn it recently.

The exquisite runes flowing in those crystal-shaped ribbons are clearly primeval runes, containing mysterious powers that can connect heaven and earth and make mountains and rivers fission.

At this time, he realized that those streamers had existed in the first place, but they were usually hidden and invisible.

"Sniff!

Numerous streamers, runes inside, suddenly emitted a dazzling light.

An irresistible force burst out from the grid formed by those ribbons, rushing straight towards the Yanlong Armor.

The Yanlong armor that was trying to sink was pushed by that force to fly back from the giant mouth and fall back onto a piece of gravel at Nie Tian's feet.

The blazing flame released by the Flame Dragon Armor seemed to dim a lot after trying it and being stopped by those crystalline streamers.

"Isolate the flame dragon armor from falling into the magma fire liquid. The lava in the center of the earth that was rolling and seemed to be surging and erupting also seemed to be blocked by the crystalline ribbons, unable to rush out of the center of the earth, unable to gush wildly. Nie Tian looked at it for a while, his eyes were full of surprise, and he was seriously thinking about why the densely intertwined ribbons hidden deep in the heart of the earth existed.

"Whew!"

While Nie Tian was secretly pondering, the Yanlong Armor, which had just stopped for a while, flew out again, falling straight towards the magma fire water under the giant mouth.

It was the same as last time, and inside those crystal-like ribbons, countless magnificent primeval runes suddenly lit up again.

The next moment, Nie Tian saw that the Yanlong armor was pushed by a strong force again, and it was thrown out again.

This time, Nie Tian was finally sure that the reason why Yan Long Armor insisted on reaching the depths of the earth's core despite his persuasion was to pour into those magma flames from the center of the earth.

Unfortunately, the ribbons that cover the magma and fire seem to cut off any living beings and objects from falling in.

Not only that, but the boiling and furious flames of the Earth's Center were also blocked, unable to erupt and ignite the extinct volcano and make it violent and blazing again.

Nie Tian, who was standing on the side, stayed for a short time before he saw Yanlong Armor try again.

But the result remained unchanged, and the Yanlong armor was still thrown out of the giant mouth and turned away again.

After three times, the flame light released by the Flame Dragon Armor became more and more dim.

It finally stopped, and did not continue to move, but it still ignored Nie Tian's shouts, and still insisted on staying outside.

It still doesn't seem to give up, it seems to ...... Still waiting for something.

Time passed little by little, and Nie Tian noticed that the steaming, fiery red smoke seemed to be attracted by the Yanlong Armor, and flowed into the blood core on the Yanlong Armor's chest little by little.

The smoke, which also comes from the molten earth flame in the center of the earth, also has a faint power of fire.

The Yanlong Armor failed to work three times, and after consuming a lot of strength, it seemed to be regaining strength through the fiery red smoke that was better than nothing, waiting for the next impact.

Nie Tian was very anxious in his heart, he just wanted to leave this ghost place as soon as possible, and wanted to leave the Chiyan Mountain Range.

But the Yanlong armor was always waiting, and he was reluctant to discard the Yanlong armor, so he could only wait helplessly.

At this moment, he gradually became convinced that the combined Yanlong Armor was a spiritual weapon that had reached the psychic level!

Only a psychic-level spiritual weapon can respond to his soul cry, establish a subtle soul connection with him, and take the initiative to break away from him and act with his own consciousness.

The spirit weapon has produced an independent consciousness, and with wisdom, it can be channeled, and it can be called a psychic spiritual weapon!

According to his master, Wu Lian, not to mention leaving the Heavenly Domain, even the nine realms of the entire Falling Star Land, and the spiritual weapons that have reached the psychic level are very rare.

Such a rare treasure, he would rather risk death than let go.

So he waited hard, just waiting for the moment when the Yanlong armor gave up, and immediately stayed away from this place with the Yanlong armor.

After another while, he looked numbly at the magma and fire liquid under the huge cavern, and suddenly saw that the flame juice became more and more turbulent and boiling.

This time, the Yanlong Armor did not move, and the countless crystal-like ribbons that could cover those lava and fire waters, and the primeval runes inside, all became brilliant and dazzling!

Nie Tian's eyes widened, and he looked down in amazement, and suddenly saw that there seemed to be a huge blurred shadow moving in those fiery flame juices.

Naturally, he released his spiritual consciousness and wanted to perceive.

"Whew!"

But the spiritual consciousness he released, as soon as he approached those crystal-like strange ribbons, disappeared into intangibility, and there was nothing left.

"Whew!"

At this moment, an earth-shattering beast roar came from the blurred shadow of the magma and fire.

"Boom!"

Nie Tian, who was caught off guard, had a splitting headache, and the corners of his mouth and nostrils couldn't help but flow a trace of blood.

......
