Deep in the canyon, dense trees obscured the ground, and an iron-spine wolf lurked in the grass more than a person high, ready to search for passing monsters.

"Hiss~"

There was a sudden and soft sound, and a black shadow seemed to pass by on the branches.

The Iron Ridge Wolf lowered its body and sniffed carefully, and then lurked again, the faint aura of the second-level demon beast was not enough to make it take precautions, and the speed of the black shadow was obviously not the target of its predation......

Behind a boulder a hundred meters away, the black shadow wiped the cold sweat from his forehead, this was already the fifth third-level demon beast he had avoided in two days, and the closer he got to the depths of the canyon, the more high-level demon beasts grew.

"Fortunately, with the effect of this demon qi pill, they really treat me as a weak demon beast...... I don't know if the birth of this strange treasure has anything to do with the turmoil of the heavens and the earth, but Ling Lao said that the changes in the heavens and the earth must have abnormal phases, and we can't help but find out the reason in order to prepare for the catastrophe, and it is related to the safety of the entire Anxi Province", he underestimated it in his heart, and then continued to use his divine sense to warn the surroundings, and slowly dived into the depths of the canyon.

This black shadow was naturally Lin Fan, and after thinking about it for a while, Mu Qingyun still allowed him to carry out this dangerous mission.

The fledgling under the eagle's wings can never soar into the sky, only by experiencing wind and rain can the future be achieved, if Lin Fan has been living under his wings, he will not be able to become a strong man, because the strong are never cared for, and the second calamity of the nine tribulations is coming, and there is not enough strength......

So after Mu Qingyun was approved, Feng Lao took out the Demon Qi Pill and made a detailed map of the canyon, and Mu Qingyun and everyone instructed Lin Fan to stay in place and wait for his return.

Lin Fan stepped into the depths of the canyon under the expectant gaze of everyone.

......

Holding the map drawn by Feng Lao in animal skins, Lin Fan carefully identified the surrounding environment.

"It looks like we're almost in the area where the earth fire erupts, so there shouldn't be any monsters there......

However, Yang Ce said that now that the lava pool has shrunk a lot, and the temperature in the vicinity has dropped a lot, the demon beasts should be very clear......

You can only take one step at a time."

After thinking for a while, Lin Fan put away the map and continued to go inside.

An hour later, after Lin Fan walked out of this wood, a strange rocky wilderness came into view.

At a glance, there was rubble everywhere, and strangely shaped boulders of a height were all over the gravel, and the wilderness was not flat, and the terrain was getting lower and lower all the way forward, but the temperature around it was gradually rising.

The gravel wilderness has a wide field of view, and there is no shelter except for a few boulders that can be hidden.

Although he couldn't see any demon beasts, Lin Fan still cautiously moved forward slowly with the help of boulders as cover.

But after a few hours, until the sky gradually darkened, not a single demon beast found it, but the temperature around it was getting higher and higher, and the sweat on Lin Fan's body slipped down like raindrops......

As the sky darkened, it could be seen that there was a fire in the far distance, and the fire that suddenly lit up and quickly extinguished flickered in the distant wilderness.

"What is this, are the demon beasts setting off fireworks......", Lin Fan wondered.

But without waiting for himself to take a closer look, suddenly a sense of crisis came out from the bottom of Lin Fan's heart, and a cool breath seemed to crawl from the tail vertebrae down the spine to the top of his head, Lin Fan's whole body was tense and his heart was beating wildly, and he could sense that the air around him suddenly became hot without his divine sense, and the gravel under his feet suddenly shook violently.

"Bad ......"

Lin Fan exclaimed, his speed increased to the limit, and he accelerated more than twenty meters away, but the moment he just landed......

"Whew~"

Behind him, where he had just stood, a huge pillar of fire with a diameter of more than five meters and a height of dozens of meters suddenly spun and rose from the ground, and quickly disappeared under the night sky.

This pillar of fire came and went in a hurry, if it weren't for the fact that the temperature of the surrounding air had risen a lot, accompanied by the smell of sulfur, Lin Fan would have even thought that he was dazzled.

Looking at the area where the pillar of fire rushed out of the ground, the red gravel that was now scorching, Lin Fan's heart was beating wildly, if his reaction and speed were a little slower, I am afraid that he would have turned into charcoal by now......

Looking at the red rubble that emitted heat with palpitations, and then at the flickering fire in the distance, Lin Fan swallowed his saliva and said with a bitter face, "This is the earth fire, right......?" No wonder there are no monsters here, but I'm afraid that they will turn into charcoal......"

According to the induction just now, there was no warning of this fire before it erupted, and the position where the distant fire seemed to appear was not fixed, and only the moment it erupted from the ground could it be prevented by the vibration of the rubble under his feet.

"The boulders are heavy and there are no gaps, and there should be no earth fire gushing out from under those strangely shaped boulders, and the earth fire should only erupt ...... this gravel ground with gaps," Lin Fan made an inference after observing the surrounding environment.

Don't wait for him to finish.

"Whew~~~"

A huge pillar of fire suddenly gushed out from under a boulder in front of him, and the pillar of fire rotated and wrapped around the boulder, and because of the blockage of the boulder, the pillar of fire did not rise into the air, but spun like this, and scorched the boulder for more than ten seconds until the flame energy was exhausted, and the pillar of fire gradually disappeared.

Lin Fan's eyes widened and he opened his mouth to look at the boulder that was roasted by the earth fire, his whole body was red and melted, and his right eyelid jumped wildly a few times, and at this moment he finally understood how this strange-shaped boulder was formed......

"Well, I was wrong......

It seems that I have thought too much, and it is more dangerous for the pillar of fire to not rise under the barrier of the boulder......", Lin Fan overturned his previous speculation, and at the same time dispelled the idea of dodging the earth fire on the boulder.

He doesn't want to be a roast duck yet......

Looking at the constantly flickering firelight in the distance and the surrounding environment, Lin Fan gritted his teeth, his divine sense shrouded the ground around him, and he ran all the way to the depths of the wilderness with his feet.

......

"Whew~"

ran for most of the hour, and narrowly avoided a ground fire.

Lin Fan gradually made some discoveries, in addition to the fact that the ground would shake a little before the eruption, a small area of the eruption that had erupted would not erupt a second time in a short period of time due to the temporary release of underground energy.

This was definitely good news for Lin Fan, who kept his eyes on the front as he ran, keeping his eyes firmly on the place where the fire was shining, and then tried to pass through the edge of the fire area that had just erupted.

Although it was impossible to write down the location of the eruption of the ground fire in a hurry, fortunately, the ground gravel would be burned red after the eruption of the ground fire, which was especially conspicuous in the night, which also made Lin Fan feel very relieved and made full use of it, and finally made the next journey a little easier.

But even so, Lin Fan still dodged after a few inductions, and was almost swept away by the earth fire.

"Whew~"

A small pillar of fire suddenly burst out from the sole of his foot without warning, hitting Lin Fan directly.

Lin Fan was shocked in his heart, the smaller this pillar of fire rose out, the weaker the vibration caused by it, and he couldn't sense it at all......

Lin Fan only felt a scorching heat around him, and there was a sharp pain all over his body, Lin Fan desperately urged Zhenyuan to protect his body, but Zhenyuan's isolation from the high temperature was very limited, and his skin instantly turned red and there were even small blisters bulging out of his skin.

"It's over......", Lin Fan exclaimed.

"You idiot, quickly urge the Dharma Body ......"

Just when Lin Fan felt puzzled, Ling Lao in the Shenhai space shouted violently.

Lin Fan's heart was shocked, and he hurriedly ran "Five Yuan Transformation and Life Decision".

In the Shenhai space, the "Transformation Tree" emitted a faint green light that lingered on the surface of Lin Fan's body, and the green light isolated the high temperature to repair Lin Fan's injuries while actually wrapping the slightest ground fire and dragging it towards the Shenhai space.

Lin Fan felt something, wrapped all the ground fire around his body with the pale green true yuan released by the "Transformation Tree", and controlled the entangled earth fire to slowly approach one of the taproots of the "Transformation Tree".

One of the taproots of "The Tree of Transformation" sensed the approach of the earth fire and emitted a faint fluorescence, quickly absorbing these earth fires and slowly absorbing them.

Lin Fan sensed the actions of the "Transformation Tree" and was overjoyed in his heart, these five taproots need to absorb five kinds of energy respectively, and the Fire Yuan Crystal will definitely not be able to find it for a while, but I don't know if absorbing some earth fire will work......

Lin Fan carefully observed and comprehended, the taproot absorbed all the earth fire that was dragged into the Shenhai space in a few breaths, and after a few faint fluorescence flashes on this taproot, the taproot gradually returned to its original fluorescence and disappeared, but at this time, there was a thin red fluorescence on the taproot.

This thin one is really too far away from the entire taproot, Lin Fan dragged his chin and secretly calculated for a long time, feeling that if he wanted the entire taproot to turn red, it was estimated that he would have to absorb at least a few thousand earth fires......

And look at myself now, my clothes are scorched, my hair is smoking, half of my eyebrows are almost burning, the redness on my body is gradually fading, and the slight burns have almost been restored by "The Tree of Transformation".

But this process continues thousands of times......

Not to mention how long it will take to complete, it is still unknown how many times he can resist the earth fire, Lin Fan thought about it......

Forget it, it's more realistic to find the Fire Element Crystal.

Looking at the thin red streaks on the taproot that emitted faint fluorescence, Lin Fan had a deeper understanding of the first sentence of "Five Yuan Transformation and Life Decision".

It seems that it is not only, the essence of the gold element, the marrow of the wood element, the flower of the water element, the crystal of the fire element, and the core of the earth element, these five kinds of heaven and earth wonders.

As long as it is pure heaven and earth energy, the taproot of the "Transformation Tree" will absorb it, but these energies are relatively thin, so it has little effect.

And with this experience, Lin Fan was not so afraid of the ground fire, and adjusted his route and continued to approach the depths of the canyon.
