In the valley of the desolate fire in the center of the earth, the temperature is getting higher and higher, and everywhere you enter the eyes, it is all red, which makes people feel that their eyes are red and painful.

Chu Duan advanced rapidly, penetrating seven hundred miles into the Valley of Desolate Fire in the center of the earth, bursts of scorching qi continued to seep into his body, everywhere, and confronted the power of ice in Chu Duan's body.

In the confrontation, the power of the ice spirit was consumed a little bit, and the speed was extremely fast, and the high temperature that invaded the body was weakened, and it was only about fifty percent, which made Chu Duan feel very uncomfortable, and hurriedly took out a flawless quality ice spirit pill and swallowed it.

The effect of the Flawless Quality Ice Spirit Pill is good, and with the Ice Spirit Frost Skill, the temperature in the body drops sharply, all the scorching power is quickly dispersed, and the cold qi hits the whole body, which is very comfortable.

Chu Duan silently felt that Dacheng's Ice Spirit Frost Skill combined with the Flawless Quality Ice Spirit Pill had actually weakened the temperature by more than ninety percent, plus his cultivation to reach the sixth turn of the Nine Transformations Realm, he could completely fight against it, and it was effortless.

Seven hundred miles is considered to be the deep part of the Central Wilderness Fire Valley.

Along the way, Chu Duan heard some intermittent conversations about the desolate heat of the earth's heart.

It seems that the desolate flame in the center of the earth was severely injured by a sword king and hid, and if it can be found, it is the best time to subdue it.

Therefore, these people went deep into the interior of the Earth's Central Desolate Fire Valley, in order to find out the badly damaged Earth's Desolate Flame and subdue it.

Chu Duan's heart moved, and this thought also came to mind.

"Dacheng Ice Spirit Frost Skill plus Flawless Quality Ice Spirit Pill...... You can give it a try. A glint flashed in his eyes, and Chu Duan said secretly, going deeper again, crossing seven hundred miles.

Chu Duan entered the Valley of Desolate Fire in the center of the earth many times, this was the first time he had crossed the distance of seven hundred miles, and he went deep again, and the temperature really continued to rise, but under the cooperation of Dacheng's Ice Spirit Frost Skill and the Flawless Quality Ice Spirit Pill. Weakening the temperature by more than ninety percent, allowing him to deal with it calmly.

Deeper into the Valley of the Earth's Wildfire, the scene is different.

About fifty miles further, there are no more than simple lava pools and mountain walls formed by the accumulation of magma ash over countless years.

There are countless cracks in the mountain wall, and in the cracks, there is a constant flow of magma.

Chu Duan also found that there were many potholes on the mountain wall, some deep and some shallow. Some are big and some are small.

The small ones are only like fists, and the shallow ones can see the bottom at a glance, while the large ones are more than one person high, and the deep ones are bottomless.

Chu Duan swept quickly in front of these potholes, and his spiritual thoughts diffused out, showing a fan-shaped sweep out of the cavities, and there were thousands of potholes here.

Suddenly, he stopped. Because a very deep pit was discovered, and the spiritual power was condensed into a bundle, which could go deep for 20,000 meters, Chu Duan discovered. Inside, there seems to be something.

This pit is neither big nor small, and it can almost allow a person to slowly go deep inside.

After thinking for a moment, Chu Duan shrank back. The cat bent over his waist and went into the hole, and his body was as nimble as a swimming fish. Quickly go deeper, with the spirit in front of you, acting as a scout.

The temperature in the cave was getting higher and higher, and it felt as if the whole person was being roasted on a blazing fire, and the frost power in the body and the power of the ice spirit pill were mixed, releasing bursts of cold to sweep through the whole body, fighting against the scorching heat, making Chu Duan feel a feeling of dire straits, and began to feel uncomfortable.

The deeper you go, the deeper the uncomfortable feeling becomes.

Chu Duan felt as if he was constantly walking deep underground, the higher the temperature, the greater the pressure, the wider the passage, and there were countless small potholes around, like branches of the cave passage, I don't know where the passage leads.

The deeper you go, the more red the hole becomes.

About a hundred miles deep, a wide expanse appeared in front of Chu Duan's eyes.

This is an underground cavity, the size of a football field, the height is also tens of meters, thick and slender rough stalagmites hang upside down in the air, around, there are also a lot of stalagmites, one by one like a sharp sword, the whole body is dark red, exuding amazing high temperature.

This cave belly, half of the dark brown earth, half of the magma pool, the magma pool is boiling, the terrifying high temperature, is constantly emitting from the magma pool, the steaming heat fills the entire cave belly, making the air distorted, the smell of sulfur fills the surroundings, the swordsman who is not enough to cultivate comes here, he will die of suffocation and sulfur within three breaths, and his internal organs will be eroded and destroyed.

Even a swordsman like Chu Dui couldn't stay here for a long time, but Chu Duan was different, he had extremely high control over himself, because he directly shielded his breath and turned it into internal breathing, which would not be disturbed by the sulfur poison gas.

The entire belly of the cave was fiery red, red light was everywhere, extremely hot, here, it made Chu Duan feel uncomfortable, the Ice Spirit Frost Skill combined with the Flawless Quality Ice Spirit Pill only weakened the temperature by eighty.

Eighty percent is actually a very high percentage, but the temperature here is much, much higher than outside, even if it is weakened by eighty percent, it still makes Chu Duan feel uncomfortable, very uncomfortable.

Standing on the dark brown land with the eight-sided Heavenly Desolate Sword in his left hand, Chu Duan looked around carefully, and his spiritual thoughts also diffused, enveloping the surroundings, and examining them carefully.

In the corner of the magma pool, there are lotus flowers growing one after another, which are the Earth Fire Desolate Lotus that was found before.

The value of the Earth Fire Desolate Lotus is extremely high, bringing a lot of contribution points to Chu Duan, and there is more than one Earth Fire Desolate Lotus here, roughly speaking, there are at least five or more, all of them are picked and brought back to the Heavenly Desolate Earth Palace, which can be exchanged for thousands of contribution points.

Spiritual thoughts continued to be released, skimming over the boiling pool of magma, confirming that they could detect danger in the first place.

It was quiet, and nothing could be heard except the gurgling of boiling lava.

It's just that his intuition tells Chu Duan that here, it's not as safe as it seems.

Stepping forward, step by step towards the Earth Fire Desolate Lotus in the magma pool, after a while, Chu Duan walked to the side of the Earth Fire Desolate Lotus, collected the Earth Fire Desolate Lotus, collected the first Earth Fire Desolate Lotus, continued to collect the second flower, and then collected the third flower.

Soon, the five Earth Fire Desolate Lotuses were collected by Chu Duan and collected into the space ring, and when he looked elsewhere, he found one after another Earth Fire Desolate Lotus.

This place is very secretive and has existed for a long time, which is very suitable for the growth of the Earth Fire Desolate Lotus.

Each Earth Fire Desolate Lotus has existed for more than a thousand years, and its quality is several times better than the one Chu Duan found outside before, and its value will naturally be higher.

Once you have reached the sixth flower, start collecting the seventh flower.

In a short time, Chu Duan collected a total of twelve Earth Fire Desolate Lotuses, and when he was about to collect the thirteenth, he suddenly felt a palpitation, relying on his intuition that had swam on the edge of life and death many times, he immediately reacted and quickly retreated, and at the same time, a red shadow broke through the sky and shot towards Chu Duan like lightning.

A strong sense of crisis came to his face, making Chu Duan's heart beat wildly, his eyebrows seemed to be broken, his bones were terrified, his blood was cold, and the burning heat in his body collapsed in an instant.

With his extraordinary eyesight, Chu Duan saw that the red shadow was a flame snake, a more powerful existence than the flame snake he had killed before, his whole body was fiery red, and his body was like a flame crystal, crystal clear.

The speed of the flame snake was extremely fast, like lightning breaking through the sky, opening its mouth, a cloud of yellow aura gathered in it, and Chu Duan immediately felt the scorching heat that almost burned itself to ashes, and rushed towards it.

In an instant, the sword was released, and the power of the ice spirit, together with the spiritual mind and the heavenly desolate sword qi, combined with the shaking mountain energy, was launched, and a sword was sharpened.

The speed of the flame snake was extremely fast, and the speed of the sword was not slow, colliding in an instant, Chu Duan immediately felt a shock in his palm, and the sword almost flew out of his hand, while the flame snake was slashed by his sword and fell towards the magma pool in the distance.

In such a place, Chu Duan didn't dare to act rashly, the temperature of the magma was too terrifying, and there was a terrible flame snake, no, maybe more than that.

Unloading the power of the shock and clenching the eight-sided Heavenly Desolate Sword, Chu Duan's eyes narrowed, staring closely at the place where the flame snake fell, and with his strong spiritual intent, he swam and scanned on the surface of the magma pool.

The touch of Fang Cai's sword and the collision made Chu Duan know that the Yan Snake had not suffered any injuries, and that it must be hiding under the magma pool, ready to attack Chu Duan at any time.

Chu Duan looked at it and thought about whether to leave here and return to the Heavenly Desolate Earth Palace first to make his strength stronger and come back, or whether he should continue to wait for a while to see if there was a chance to kill the flame snake.

It can be imagined that this flame snake's inner dan must be better than the previous flame snake's inner dan, and maybe he can make his cultivation break through the Nine Transformations Realm and return to the Yuan Extreme Realm in one fell swoop.

Returning to the Yuan Extreme Realm and re-refining the Heavenly Desolate Sword Yuan, Chu Duan's overall strength will increase several times and become more powerful.

Standing still, the breath of the whole body is restrained, the beating of the heart is also reduced again and again, and the whole person seems to have turned into a statue.

The flame snake was also hiding, observing Chu Duan's every move, looking for the best opportunity, as if the two sides were competing for endurance.

Suddenly, Chu Duan's body moved slightly, revealing a flaw, although the flame snake had no wisdom, it had an amazing instinct, and immediately caught the moment's negligence and launched an attack.

Silently, the red lightning tore through the sky again, breaking through the magma pool, and the yellow flames condensed into a fireball, blasting towards Chu Duan, and the flame snake followed closely behind, launching an attack.

The temperature of the yellow fireball was restrained, even more amazing, Chu Duan didn't dare to take it hard, Feihong Illusion stepped into the air, narrowly avoided the yellow fireball, and stabbed out with a sword.

There was a little frost white on the tip of the sword, which was the condensation of the power of Dacheng Ice Spirit Frost Frost Skill, fusing the sword qi spiritual intention and mountain shaking power, concentrated into one point, erupted in the way of extreme entry, and stabbed on the forehead of the flame snake.

Ding, as if gold and iron collided, the powerful force exploded, a scorching storm swept away, the terrifying force of the shock made Chu Duan take a few steps back, and the flame snake also flew out upside down under this sword, Chu Duan retreated at the same time, with the help of the power of the counterattack, it rotated with the help of the power of the countershock, turning into a more fierce and ferocious attack, and a sword slashed out.
