Soon, an hour passed, and there was nothing to be seen outside of the lava flow, only bubbles popping up one by one, gurgling, and then bursting and exploding, filling the air with a rich, pungent smell of sulfur.

The temperature around the surroundings remained unchanged, but everyone felt that the heat was unbearable, and their tongues were dry, so they hurriedly took out the kettle, and the cold water in it was also heated in an instant, and the temperature began to rise, and when it was drunk in the mouth, it became warm water.

Judging from the current situation, if you hold on for another hour, some people will reach the limit, and if you hold on for another two hours, Chu Duan will also feel uncomfortable.

If his cultivation was restored to the Yuan Extreme Realm, he could persist for a longer time.

"Wait another hour to see, if not, you have to exit first, rest and recover before coming in. Pei Wushou said.

The lava river came from a distance, as if there was no end in sight, it was not static, and if you carefully distinguished, the magma flow was flowing slightly, but it was too viscous to be seen.

And I kept staring at the magma flow, and after looking at it for a long time, I felt as if my eyes were stuffed into flames, burning red and a little sour and swollen.

Half an hour passed, and except for Chu Duan, the other five felt uncomfortable with their eyes and had to close their eyes and rest for a while.

At this time, Chu Duan saw a strange air current, appearing in the sky above the magma flow, hovering from a distance, with teeth and claws, like a small snake, with a pale yellow body.

His eyes narrowed, and Chu Duan stared at the air flow more carefully, and found that the air flow was condensed but not dispersed, and a trace of scorching heat was restrained in it.

The spiritual thoughts immediately condensed into a bundle, released it, and in the blink of an eye, he touched the pale yellow breath, felt the burning heat in it, and with a movement of his mind, he turned into an invisible hand and grabbed it, and immediately grabbed and pulled the pale yellow aura, and accelerated to get closer to Chu Duan.

Tell the difference. After comparing the characteristics of the desolate fire qi in the center of the earth that Pei Wushou said, Chu Duan concluded that this was the desolate fire qi in the center of the earth, and he woke up the others and opened his eyes one by one to look at the pale yellow aura.

"The desolate fire gas in the center of the earth, that's right, it is the desolate fire gas in the center of the earth. One of them was pleasantly surprised, a little envious, but not a desire to possess.

"I'll put it away and distribute it later. Chu Duan said. Take out the prepared white jade bottle, and put this earth-centered desolate fire qi into the white jade bottle for preservation.

The others had no objection, even if Chu Duan took this Earth Heart Desolate Fire Qi for himself, they wouldn't say anything, because it was collected by Chu Duan when they closed their eyes and rested.

With the harvest of the first Dao of Desolate Fire Qi in the center of the earth, it inspired the others to stare at it with wide eyes one by one, waiting for the Desolate Fire Qi in the center of the earth to appear.

It's just that. The probability is too small and slim.

Another half an hour passed, and there was still no second desolate fire in the center of the earth.

"No, I can't take it anymore. ”

"Me too. ”

"Let's get out of here and rest for a while. ”

"Senior Brother Chu. Let's get out of the house and rest first. Pei Wushou said, although he can bear it for a while, but at most it will be about a quarter of an hour.

"You guys go out and rest first, I can hold on for a while. Chu Duan said. In fact, he could still hold out for two hours, because he had the Heavenly Desolate Sword Body and the strong spiritual intent. And Pei Wushou and the others, the Heavenly Desolate Sword Body has not even been cultivated at the first level.

"Then be careful. Pei Wushou said, turned around with the other four swordsmen, and walked towards the outside of the Desolate Fire Valley in the center of the earth, the temperature outside was much lower, so he came in after resting.

Chu Duan was like a sword, his body was straight, standing on the edge of the magma flow, staring ahead, when his eyes were sore and swollen, he closed it slightly and rested for three breaths before opening it.

In the blink of an eye, another hour passed, and with Chu Duan's good patience, it was inevitable that he would be a little impatient.

The probability of the occurrence of the desolate fire in the center of the earth is too low, and the temperature in this place is high, in this environment, the body feels scorching from the inside, and it is inevitable that you will be upset and impatient.

At this time, Chu Duan's eyes lit up, and he saw a pale yellow aura slowly circling over, no, not one, but two.

Two pale yellow breaths in a row swirled one after the other.

The trace of impatience in Chu Duan's heart dissipated, and his spiritual thoughts diffused out again, grabbing the two desolate fire qi in the heart of the earth, speeding up and approaching, and then quickly collecting them into the white jade bottle.

At this point, Chu Duan had harvested three earth-centered desolate fire qi.

What is the effect of the earth's core desolate fire qi, Chu Duan is still unclear, but in the outer palace, the price of the geocentric desolate fire qi is very high, it is said that each dish is worth a bottle of the lower grade true desolate pill, and the lower grade true desolate pill, the outer palace disciples can only receive a bottle for free every year.

Of course, the role of the Earth's Core Desolate Fire Qi and the True Desolate Pill is different, and it is really a complete comparison.

For example, Chu Duan would rather exchange most of the lower-grade True Desolate Pill for the Earth's Heart Desolate Fire Qi, so that he would be able to better refine the Heavenly Desolate Sword Qi.

Pei Wushou and the others recovered, walked in, and continued to wait.

An hour passed, and there was no gain, Chu Duan turned around and walked out of the Valley of Desolate Fire in the center of the earth and went outside to recover.

When you are tired, you rest, and when you recover, you go to the side of the magma flow, during which some teams also pass by, but they all go deeper into the Valley of the Desolate Fire in the center of the earth, and they do not snatch it with Pei Wushou and others.

And so, three days passed.

Although I am tired of leaving the Valley of the Wildfire in the Heart of the Earth to rest outside, I will feel tired and tired from the bottom of my heart when I stay here for up to three days.

Therefore, Chu Duan and the others discussed it and decided to return to the Heavenly Desolate Earth Palace first.

Although I felt mentally tired, after three days, I still gained something more or less, so everyone's heart was very happy.

The distance of thousands of miles was not far for them, and there was no danger along the way, and the six of them did not stop, passing by a city, and rushed to the mountain gate of the Heavenly Desolate Divine Mountain.

Enter the mountain gate, go up the stairs, and return to the outer palace of the Heavenly Desolate Palace.

"In the past three days, we have obtained a total of forty Dao Earth Desolate Fire Qi, now, let's distribute it. Pei Wushou said, his tone was a little excited.

"This time, Senior Brother Chu contributed the most, and I suggest Senior Brother Chu to allocate the most. One of them said.

"Seconded. ”

"Well, if it weren't for Senior Brother Chu, I'm afraid that we would have been kicked out and wouldn't have gained anything, so we should take the big head. ”

The people Pei Wushou was looking for had a good mentality, and they all agreed that Chu Duan would take the lion's share, in fact, among the forty Dao Dao Desolate Fire Qi, Chu Duan alone collected 12 Dao, and the remaining 28 Dao was collected by each of them.

It's just that they are a team, and they have already agreed to be distributed together.

"In this way, Senior Brother Chu will share the ten Dao Desolate Fire Qi, and the five of us will divide the remaining thirty equally. Pei Wushou said and looked at Chu Duan: "What does Senior Brother Chu think?"

"Okay. Chu Duan had no objections, and neither did the other four.

After the happy distribution, everyone agreed that they would separate after acting together next time.

Chu Duan returned to the room with the ten earth-centered desolate fire qi, intending to test the effect of the geocentric desolate fire qi.

The sword qi cultivation at the beginning of the Qi Sea Realm, but in terms of the degree of refinement, it is extremely high, but it has not yet reached the limit.

Sitting cross-legged on the bed, Chu Duan took a deep breath, exhaled slowly, and then exhaled slowly, eliminating distracting thoughts, and then, took out the white jade bottle, and took out a piece of the earth's center desolate fire qi from it, and with a mouth, the pale yellow geocentric desolate fire qi was immediately inhaled from his mouth, down his throat, and into his stomach.

Suddenly, Chu Duan felt that there was a warm air flow circling in his stomach.

The spiritual mind entered the body, seeing everything in the body, the Heavenly Desolate Sword Qi was carried, and Chu Duan controlled the desolate fire qi in the center of the earth into the dantian, and then, with the carried Heavenly Desolate Sword Qi swirling in the meridians.

The desolate fire qi in the center of the earth is constantly burning, and the desolate sword qi is purified little by little, and it is also constantly consumed in the process of purification.

Time passed, a quarter of an hour passed, and the desolate fire in the center of the earth was also consumed cleanly.

Chu Duan stopped cultivating, opened his eyes, opened his mouth and exhaled a breath of white air, which shot into the sky like a sword, and only dissipated a few meters away.

"Yes, the effect of refining is obvious, three more ways, I can quench the Heavenly Desolate Sword Qi to the limit, and I will be able to break through to Xiaocheng. Chu Duan said secretly, took out the white jade bottle again, and ingested three earth-centered desolate fire qi at one time.

With the Heavenly Desolate Sword Body of the second layer of Chu Duan, it can completely withstand the high temperature scorching of the three Earth-centered Desolate Fire Qi, and the Heavenly Desolate Sword Qi is carried up again, with the scorching of the three Earth-centered Desolate Fire Qi, the purification speed of the Heavenly Desolate Sword Qi is faster.

This time, it took a full three quarters of an hour for the three Earth Center Desolate Fire Qi to be consumed, and Chu Duan's Heavenly Desolate Sword Qi had also been obtained to the current limit as he wished, and it could no longer be refined, it was time to break through.

He took out the porcelain bottle, poured out five lower grade true desolate pills, threw them directly into his mouth and swallowed them, the power of the elixir dissolved, forming a strong impact, Chu Duan immediately carried the Heavenly Desolate Sword Qi and cultivated.

The more pure the energy, the more energy needs to be absorbed when breaking through, just like Chu Duan's now, his Heavenly Desolate Sword Qi is really too pure, dozens of times purer than other Qi Sea Realm entry swordsmen.

Therefore, if Chu Duan wants to break through, the energy required is also many times that of other swordsmen, and the medicinal power of the five lower grade true desolate pills was exhausted, but Chu Duan was stuck on the edge of the breakthrough, he quickly took out five lower grade true desolate pills and threw them into his mouth, quickly swallowed them, and the medicinal power dissolved again.

This time, the energy provided was sufficient, and when the medicinal power of the five lower grade True Desolate Pills was fully absorbed, there were bursts of explosions in Chu Duan's body, as if firecrackers, and the Heavenly Desolate Sword Qi instantly burst in the meridians, splitting and surging, and the surrounding Pure Desolate Qi was injected into Chu Duan's body like an empowerment, and it was quickly transformed into Heavenly Desolate Sword Qi.

A quarter of an hour later, everything fell silent, and Chu Duan's cultivation also successfully broke through, and the Qi Sea Realm was Xiaocheng, and the overall strength was slightly improved.

Without feeling any joy, Chu Duan didn't stop, took out the remaining six Earth Desolate Fire Qi, and sucked it into his stomach at once, refining the Heavenly Desolate Sword Qi that had just broken through. (To be continued......)
