Having found a suitable training place for the Jade Blood Flame, Le Yun flew to the center of the fire cave, then descended to the surface of the magma lake, and then jumped into the hot magma again.

When a person falls into a magma lake, the calm magma layer becomes turbulent, creating a circle of ripples. When a person sinks into the magma, the ripples become slower and slower, and soon resume. calm.

The magma in the fire cave is denser and more viscous than the magma in the criss-crossing tunnels. Leyun sinks into the magma flow, and the magma sticks to the surface of the robe like glue, with very little resistance. big.

Of course, no matter how much resistance there is, it cannot stop her from diving. At most, she can only walk slower.

After diving for more than eight thousand feet in the thick magma, we finally reached the bottom of the fire cave.

The fire cave looks like an ordinary fire cave, and the bottom is the same reddish brown as the cave wall.

But in Le Yun's eyes, there is a secret hidden at the bottom of the fire cave - there is an invisible barrier at the bottom.

The invisible barrier is about one foot wide, invisible, colorless and without aura fluctuations. In Le Yun's eyes, it looks like a layer of luster on the surface of the rock.

But it is undoubtedly a barrier.

Le Yun was able to find where the barrier was because the aura of the ground corresponding to the fire cave where it was located was a bit denser than other areas, and the surrounding ores were more and of purer quality.

Of course, she can only distinguish the intensity of the spiritual energy, and does not know what is in the fire veins. Even if she finds the destination, she can only identify the densest spiritual energy in the central area of ​​the fire cave.

She thought there was a gestating fire hidden deep in the magma. She only knew the secret realm of the fire cave when she dived to the bottom of the cave and saw the invisible barrier.

Sneaking to a distance within reach of the barrier, Le Yun sensed it. The invisible barrier was stable and solid, and she could not sense any ominous energy.

The light of the barrier is as thin as cicada wings, but Le Yun's sight cannot penetrate it. It is a natural barrier naturally derived from the power of heaven and earth, not man-made.

There is a natural barrier formed by the power of heaven and earth, which means that there must be spiritual objects or rare treasures from heaven and earth within the barrier.

The natural barrier is located under the fire cave. Visually, spiritual objects or rare treasures from heaven and earth are related to fire.

After a little analysis, Le Yun made a bold guess - there is likely to be some kind of rare heaven and earth spiritual fire or spiritual fire within the barrier.

With speculation in her mind, she was also a little excited.

In order to confirm whether her guess was correct, Le Yun entered the barrier without hesitation.

Going in and out of man-made boundaries, for safety reasons, she often follows the characteristics of the formation.If the door is in an auspicious position, there are no restrictions on traveling to and from the natural boundary.

There is no rejection when entering the barrier, but the feeling of dizziness and dizziness cannot be avoided.

After a short moment of dizziness, Le Yun entered a silent and silent world, and all she could see was a red rock wall.

The red color of the rock wall is so dazzling that it looks like a red light with fifty-cent special effects, making it difficult for people to look directly at it.

The red color is warm and unrestrained, dazzling and luxurious.

"Fire element... spiritual gold?" Le Yun saw the red rock clearly and was so shocked that she moved to the wall and couldn't help but reach out and touch it.

The rock wall is as smooth as a mirror, red as a burning flame, and filled with hot breath.

Touching the rock wall, Le Yun confirmed that it was not her eyesight. The red rock wall was pure fire spiritual gold.

At the same time, even with the protection of the immortal robe, she still felt the blazing fire energy coming from the sky and the earth. People in the robe's light shield still felt like staying in a sauna. The heat was coming from all around, making people sweat.

The temperature inside the barrier is dozens of times higher than the temperature of the magma outside the barrier. If an ordinary person were dropped, it would be burned to ashes in less than a minute.

The temperature in the barrier was too high, and Le Yun couldn't bear it. She wiped the fine beads of sweat from her forehead, took out two array disks and threw them at her feet, then reluctantly took out another Cut the ice bone and place it on the array plate to cool down.

At such a temperature, hundreds of millions of years of ice will not have much effect.

As soon as the Ice Bone appeared, there was a hint of cold air. The cold air immediately drove away the heat, causing the temperature inside the robe's light shield to drop sharply.

With the ice bones, the inside of the robe light shield has become an air-conditioned room, which is very comfortable.

After adapting to the temperature changes, Leyun observed the environment.

She landed in a solid cylindrical cave, which was about one mile in diameter. The four walls were made of pure fire-type spiritual gold. There was a thin layer of fire gold about five hundred feet above her head. Enchantment.

Looking down, the cave looks like a bottomless pit with no end in sight.

The fire-type spiritual gold was heart-wrenching, but Le Yun resisted her desire to be a mining rat and walked downwards along the cave.

The cave was very deep. She flew down thirty thousand feet, and the fire spiritual gold on the cave wall turned into a green spiritual gold mine. About thirty thousand feet further down, The green spiritual gold mine turned into a jet black spiritual gold mine.

About four thousand feet further down, the jet-black spiritual gold mine turned into dragon-patterned black rock divine gold.

Seeing the familiar dragon-patterned black rock divine gold, Leyun had a hunch that the bottom of the cave should not be far away!

　The facts were as expected. After flying less than five thousand feet, a red light was faintly visible below. As it continued to move downward, the red light group became larger and brighter, and the temperature in the cave also steadily increased.

Flying further down for more than 10,000 feet, the vertical cylindrical cave reached the bottom.

Below is an underground sea of ​​​​fire as vast as the sea. Above the sea of ​​​​fire is a sky like a sky curtain. The cylindrical cave seems to have a skylight on the sky.

The ceiling of the sky above the sea of ​​fire is entirely made of dragon-patterned black rock divine gold. The surface of the sea of ​​fire is about nine thousand feet away from the ceiling.

The magma in the sea of ​​fire is like sea water, and it creates waves even when there is no wind. The magma waves sway layer by layer, forming countless vortices.

In the central area of ​​the sea of ​​​​fire is a huge vortex. The center of the vortex is a huge rock with a diameter of more than ten thousand feet, shaped like a mountain, and completely transparent like crystal.

The huge rock is truly colorful, surrounded by raging fire. Ordinary spiritual eyes cannot penetrate the flame layer. The color of the fire is the standard flame color, but it condenses into a layer of fire attribute. boundary, protecting the giant rock from leakage.

A lotus-shaped spark condensed in the center of the flame, and a fire as big as an adult man's fist floated in the center of the lotus spark.

The fire was translucent, faintly cyan and gray under the light of the fire.

Le Yun entered the large underground cave of Liaodong from the vertical cave. She found that the temperature was too high and even an ice bone was not enough, so she took out another ice bone to cool down.

With the second ice bone to resist the heat, she flew downwards, and when she was about ten thousand feet away from the underground sea of ​​​​fire, she took out several billion-year-old ice and threw it into the formation plate to cool down.

Flying further down to about 700 feet away from the surface of the sea of ​​fire, Le Yun stood in the hot fire cave, looking at the fire protected by the blazing flames, her whole person was... confused .

"I think I must...have gone to the wrong place."

After staring at the fire for a long time, Le Yun muttered to herself, she knows that fire What kind of spiritual fire is it?

That fire, if I’m not mistaken, its name is “Taixu is really fire”.

The Taixu Returning True Fire is the divine fire, which can make everything return to its origin.

Taixu Huizhen Fire was born in chaos along with Chaos Spirit Fire, Jiuyou Cold Ice Flame, and Dongxu Clear Flame. It is the earliest spiritual fire in the world.

The Taixuhuizhen fire in the center of the underground sea of ​​fire naturally cannot be the Taixuhuizhen fire that was born in the ancient times. It can only be a new fire that was born naturally.

Recognizing Taixu and Zhenhuo’s fire, Leyun suspected that the way she came in was wrong.Yes, what about that? When she entered the barrier, did she step first with her right foot or her left foot?

She doubted herself once, and without saying a word, she quickly took the little fox out of the star core space. Her little heart was frightened. Being happy alone is not as good as having fun with others. She must let the little fox take a look. .

The little fox and the little monkey are busy collecting fruits and medicinal materials from the star core world every day, taking care of rare spiritual plants and farmed snow fat blood and fruit shells. They go out early and come back late every day.

After working hard all day, I slept soundly at night.

He was sleeping soundly. The little girl moved him out of the star core space and held his big tail upside down. The star was sleeping and shouted: "Little girl, little girl, why don't you become a human again? !”

“Little fox, take a look, look what amazing treasure I have discovered.” Le Yun grabbed the little fox’s big tail and lifted a fox upside down, asking him to Face the flames in the sea of ​​fire.

The sleepy little fox immediately became energetic when he heard that he had found another rare treasure. He didn’t care that the tail was still in the little girl’s hand, hanging upside down, and raised his head to look over. .

He saw the endless sea of ​​fire, saw the lotus-shaped sparks in the fire mass, and fixed his gaze on the translucent fire in the sparks.

"Tai... Taixu is really hot?!"

The little fox murmured, and then shouted: "Every day... Oh my god, this world can actually Is it really popular to give birth to Taixu?! How is it possible!"

"Why is it impossible?" Le Yun lifted the big tail of the little fox and swayed it like a swing, she was so happy Incredible, hey, the little fox was also frightened!

The little fox’s reaction was even more intense than hers, which meant that she was not a stranger.

She is mentally balanced.

"Taixu True Fire and Chaos Spiritual Fire are the most difficult spiritual fires to breed in all worlds. The conditions for their birth are very harsh. The place of birth must be a fully sealed natural fire cave. Not only To have sufficient aura, there must also be enough Hongmeng Qi for the fire to absorb.

After the fire embryo is condensed in the fire cave, it will take billions or even tens of billions of years of gestation. It may be successfully condensed into fire.

In the process of nurturing fire, if there is any accident, such as the sealed place is opened, or the Hongmeng Qi is insufficient, or the fire spirit is thin, the temperature changes, etc. For reasons of waiting, even if the fire is about to take shape, it will inevitably fail in the end.

Not to mention that Yunlan almost fell into the world, even in the spiritual world with rich spiritual energy, there is no place where there is enough space to breed Taixu and Zhenhuo. The chaotic aura of this divine fire.

The temperature and sealing conditions of this fire cave meet some of the conditions, but there is clearly no chaotic aura.Qi, this alone cannot give birth to Taixu or Zhenhuo. "

The little fox opened his golden eyes and doubted that he was alive. The spiritual energy in this place was obviously not too strong, and there was no chaotic spiritual energy. How did the fire be successfully conceived?
