Lin Chengfang rushed to a distance of more than ten zhang from the stone mountain, and the blazing heat wave rushed to his face, causing the water vapor around him to "sizzle" and steam into mist, and the scorching heat eroded directly into his body.

At such a distance, the heat is so high that it is hard to imagine how hot it must be in the stone mountain, and it is estimated that if you put fine iron into it, it can melt into molten iron in an instant.

Although the Dangang shield of the Demon Tail Warrior of the Demon Pill Realm can be invulnerable, water and fire are invulnerable, but such a strange scorching power is still difficult to stop.

Even if it is the existence of the Demon Yuan realm, if its own attributes cannot restrain the flames, it is also difficult for the Yuan Gang shield to ignore this high temperature.

It was precisely because Lin Cheng's water attribute was able to restrain the heat of the flames to a great extent that he had enough confidence to break into this ruin.

Although the fire can evaporate the water vapor from his body, there is a long river in the air that does not end in the Zhenhai Pearl, and the water is abundant, how can it be completely evaporated.

As soon as Lin Cheng's mind moved, the pale black river water quickly emanated from the Zhenhai Pearl, swirling around his body, wrapping it tightly, and not a trace of heat could penetrate in, and all of it was taken away by the steaming water vapor like a cloud of smoke.

More than a zhang away from the stone mountain, Lin Cheng suddenly jumped up, turned into a pale black dragon shadow, and directly crashed into a triangular opening three zhang high from the ground, which was a stone gate that had collapsed.

Rumble!

As soon as Lin Chengfang entered, it was like entering a hot steamer, and the rich water vapor wrapped around him was evaporated before it could operate.

A dragon groan sounded, and Lin Cheng's body was immediately enveloped by a black dragon more than three zhang long, which avoided the scorching heat.

And the skin and flesh all over his body were already roasted hot in that instant. If it weren't for the fact that its flesh is very tough. It is estimated that it will be directly cooked.

"Sure enough, it's a cave mountain!"

The entire stone mountain was almost in a burning state, emitting a reddish firelight, Lin Cheng used his silver pupil to sweep it widely, and he saw a messy cave mansion, if it was restored to its original appearance, it was estimated that the high-grade cave mansion in the middle tower of Sheyang Country would not be as good as it.

Lin Cheng did a simple search in this cave, but he didn't find any treasures, and immediately escaped from the triangular opening.

It turned out that this cave house existed independently. They don't communicate with each other. If you want to search for the next cave, you can only escape out of the mansion first.

However, after Lin Cheng came out, he did not explore other caves, but followed the stone wall of the stone mountain. Crawl straight down.

The stone mountain is conical in shape, small at the top and large at the bottom. More than 100 zhang down. It's a great pit.

Deeper, because the stone mountain was several times hotter than the coals, the surrounding land had already melted into liquid, forming a gap several feet wide, which was also enough for him to pass through.

Therefore, Lin Cheng flew down unhindered. Without the slightest hesitation

......。

Although Lin Cheng didn't know much about the structure of the Dongfu Mountain in ancient times, he was very familiar with the Demon Spirit Tower. In addition to the huge sacrificial pavilion and various deacon halls in the Demon Spirit Tower, there are many caves of different quality that have been built the most.

The reason why Dongfu is called Dongfu is Dongfu. It's because it's not just a place to stay, but a place full of pure demon aura that helps the Demon Tail Warrior cultivate.

And this massive amount of demon aura is not something that the demon spirit bead can afford, but is provided by the spiritual veins buried deep at the bottom of the demon spirit tower.

Because the demon aura is supplied from the bottom up, this makes the concentration of the demon aura decrease from the bottom to the top, and the higher it goes, the thinner it becomes.

In this way, of course, the quality of the cave house also decreases from the bottom to the top.

In fact, all the high-quality caves in the Demon Spirit Tower are underground, and the part that is exposed to the ground is all low-quality caves.

The surroundings of this stone mountain, from top to bottom, are all covered with caves. If you want to provide spiritual power for so many caves, the spiritual veins at the root of the mountain will definitely not be small.

Lin Cheng's purpose of going down was precisely for that spiritual vein. As for the treasures that might exist in the cave, he directly ignored them.

......

"Sneer......"

The three-zhang long black dragon slid rapidly on the scorching mountain wall, and the water and fire struck each other, making a violent sound, and the mountain walls along the way burst straight open, revealing thick cracks.

Flying to the depths of the ground, Lin Cheng sensed the fluctuations of the telekinesis of several demon powers. Obviously, they also infiltrated the cave at the bottom to search for treasures.

"Who?"

A demon master sensed Lin Cheng's breath, and although he didn't find out his cultivation for a while, he sensed the arrival of a strong man, and he was immediately frightened and snorted coldly.

When Lin Cheng heard this, he didn't pay attention to it at all, and threw it straight down.

An old man suddenly leaned out of a crack, only to see a black dragon shaking its head and tail sweeping downward, and he was immediately taken aback, and said in a lost voice: "Dragon people!"

Then, he hurriedly drilled back into the crack, apparently making some big discovery.

......

After hundreds of breaths, Lin Cheng dived to the root of the mountain more than two hundred zhang deep, and the narrow gap was full of red lava, and there was no way out.

With a slight spin in his mind, he climbed a few feet upwards and burrowed into a lava-filled fissure, which contained a cave that had long since collapsed.

The heat here is unbearable, the Zhenhaizhu in Lin Cheng's belly is running rapidly, and the suspended river water is constantly injected into the black dragon, and thousands of catties will be consumed in a few breaths, which is really terrifying.

In such a place, even the powerful Yuan Gang in the late stage of the Demon Yuan is estimated to be difficult to resist, but Lin Cheng skillfully used the principle of water to overcome fire and escaped here safely.

"Boom la la ......"

Lin Cheng walked to the innermost part of the cave mansion, opened his mouth, and spat out a column of water the thickness of an arm, spraying towards the scorching wall.

A piercing explosion sounded, and a thick mist of water steamed and surged, instantly filling the entire cave, and cracks several feet wide immediately opened in the walls.

Lin Cheng walked into the crack without hesitation, and the water in his mouth was still spraying, constantly going deep into the stone wall that was originally difficult to break.

A full quarter of an hour later, but listening to a few crisp air sounds, the stone wall nearly 100 zhang thick was actually pierced by Lin Cheng in this way.

He escaped from the crack and suddenly floated through a dark red, fiery circular passageway, with a faint stream of heat carrying him upward.

The circular passage was two feet in diameter, running straight from the bottom to the top, and was filled with vines that had been charred into char, apparently a pipe used to transport spiritual energy.

"It turns out that this mountain is really burning, could it be a spiritual mountain with fire attributes?"

Lin Cheng looked at all this, and he was really a little shocked. When he walked among the stone walls, he found that all the stones were burning with scorching flames, and the flame strength was dozens of times stronger than the flames ignited by the fire attribute lower grade demon spirit beads......

Originally, he didn't expect to be able to find this aura channel, but through the "double vertical eyes", he observed the faint fluctuations emanating from it, and he followed this fluctuation and found it.

"I want to see what the legendary spirit vein looks like!"

Although Lin Cheng had often heard of the name of the spiritual vein, he had never seen the real spiritual vein, so he couldn't help but be a little excited at the moment, licked his lips, and plunged downward.

Not long after, Lin Chengcheng rushed to the bottom of the passage against the powerful heat current, and suddenly saw a huge lava fire pool of hundreds of acres, and in the pool there was a small hill that seemed to be like a snake winding and coiling.

The hills are uneven, inlaid with dense red stones, some are the size of a fist, some are the size of a skull, crystal like jade, exude a flashing red glow, beautiful, very beautiful, mysterious.

"Is this the fire spirit vein left over from the ancient period?

Seeing this, Lin Cheng was really shocked in his heart, and at the same time extremely excited. Not to mention a whole spiritual vein, even a stone on top of that spiritual vein is estimated to be a priceless existence.

Lin Cheng grinned, and immediately spit out Zhenhai Zhu, casting the peerless magic seal "Heavenly Seal". The two dragon spirits poked out of the hanging river and turned into huge dragon arms, grabbing straight towards the spirit vein.

The double dragon is a mysterious spiritual creature derived from the Zhenhai Pearl, and its power is extremely great, and it immediately swept away the red magma, grabbed the spiritual veins into the giant hand, and suddenly scooped it up.

The winding spiritual veins slowly rose, and the magma on it flowed down like a waterfall, which looked really spectacular.

However, when the dragon arm pulled the spiritual vein up dozens of zhang high, this thing was like a living thing, and it writhed slowly, as if it was struggling......
