Cultivation has no years, the most boring, and time passes in the blink of an eye.

This month, Yunchen's Qi Yuan system gradually moved closer to the middle stage of the Huayuan Realm, and 1,500 medium-grade Yuan Stones were frantically consumed by him, and all 500 pieces of them became waste stones in a month.

Finally survived for the second month......

Yunchen entered the Fire Cloud Cave again.

"Ten days?"

The guard deacon of the Huoyun Cave heard Yunchen say that he would directly spend ten whole days cultivating in the Huoyun Cave, and the corners of his mouth twitched.

It's all over once, what's the matter?

"Hmm, please open the formation door, senior brother!" Yunchen nodded.

"Okay, okay!"

The guard deacon nodded, and he couldn't say anything, he could only sigh that the disciples of the Martial City List didn't use the cultivation time as money.

As soon as the array gate opened, Yunchen flashed into the Fire Cloud Cave and came directly to a depth of nine hundred zhang.

Yunchen had no pressure to enter such a depth, which made him feel incredible.

Looking at the deepest part of the thousand, Yunchen exhaled, and the restlessness of the mixed element fire in his body became stronger and stronger, which proved that there was really something in the deepest part of this fire cloud cave that attracted it.

Thinking of this, Yunchen supported the body protection qi element and walked to a thousand zhang depth, but even if he supported the body protection qi element and his own body strength, this first thousand zhang flame still made him feel that his whole body was scorched.

He figured he wouldn't be able to survive thirty breaths here.

"Underground?"

Yunchen endured the burning pain on his body and swallowed as he looked at the rolling magma on the surface.

He slowly ran the Hybrid Element Technique, and the Hybrid Element Flame in the palm of his hand became restless at this time, and then frantically absorbed the power of the flames in it, and soon a piece of magma under his palm turned into a charred rock.

"There is a way to ......"

Retreating to the ninth hundredth zhang, Yunchen adjusted his state slightly, the power of the flame at the first thousand zhang was really too strong, Yunchen believed that even Muhe's fire did not have such a high temperature, it was simply suffocating.

After a few moments, Yunchen traveled to a depth of 1,000 zhang again, and then activated the Mixed Element Flame and began to absorb the power of the flames of the surface magma.

Repeating this back and forth, Yun Chen only stared at one place to absorb and refine, and soon a large area of scorched black rock appeared in front of Yun Chen.

Then his eyes lit up, and a giant roaring sword appeared in the palm of his hand, and the next moment his eyes flashed and a sword smashed down......

Bang!

An explosion sounded, and a huge pit suddenly appeared under the Roaring Sword.

Looking at the deep pit in front of him, Yunchen frowned, because the Giant Roaring Sword was not a treasure weapon and could not infuse Qi Yuan, so with the power of his physical body alone, his destructive power was much smaller.

Then Yunchen's eyes lit up, he put away the Giant Roaring Sword, and a silver spear appeared in his left hand, which was the treasure spear that Yunchen had not paid much attention to, Youlong.

In fact, he had never used a treasure weapon before, and today was the first time, and the dragon spear was cold in his hand, and a trace of coolness suddenly came from his own hot body.

He tried to infuse his qi yuan into the dragon lance, and his eyes lit up.

"This is the treasure?"

After the qi yuan was poured into the dragon lance, Yun Chen felt the difference, because it was indeed similar to the description of the shopkeeper, and it could really enhance the power of the qi element, about forty percent.

"No wonder everyone wants a treasure weapon, with a treasure weapon in hand, the combat strength will also be greatly improved. ”

Putting aside such thoughts for the time being, Yunchen poured Qi Yuan into the Dragon Lance, and then burst out with the strength of his whole body, and slammed the ground with the spear in both hands.

Rumble!

There was an explosion again, and Yun Chen himself flew out and retreated to the ninth hundred zhang level, he underestimated the power of his own gun, although it was only brute force and did not use any martial arts, but this brute force also shocked Yun Chen.

Looking at the thousands of feet ahead, a huge pit suddenly appeared, and under the deep pit was a fire and water staircase, and the thick magma was like molten iron that had been burned for thousands of years.

How long does it take to burn the earth beneath the surface to such an extent?

Seeing this, Yunchen finally had an idea.

That is, there must be a fire at the source of this fire and water, and the mixed element fire is so restless because there is a fire hidden in this fire cloud cave!

There are many places in this world that resemble volcanoes, volcanoes erupt, but by no means for no reason, but because there is a powerful fire in the volcanic body.

The fire is hidden in the ground, because the fire is never extinguished, so it will always burn, and the powerful fire will melt everything in the world.

This is the case with the formation of volcanoes, when the fire is constantly scorching the ground, and when the mountain is melted and fragmented, the volcano will enter the eruption period, and the consequence is destruction.

In this world, fire is a thing of destruction, even the faintest kindling, as long as it is long enough, it can burn the whole world, and not a single grass will grow.

Yun Chen originally thought that the Ten Great Cultivation Ground Fire Cloud Caves were made of local materials, and the power of the flames here was the running formation, but he didn't expect that in fact, the role of the formation was not to operate the power of the flames, but to disperse the power of the flames, and the flame area from level one to level ten.

And the real source of the power of the flames in this fire cloud cave is actually a tinder.

Who put it? The Lord of Martial City? This made Yunchen ponder slightly, his guess should not be wrong.

"It turns out that the top ten cultivation places are not only cultivation grounds, but also chances, the gravity field refined in the gravity room last time is like this, and the same is true of the fire in this fire cloud cave!"

Yunchen guessed that each of these ten cultivation places should be an opportunity, but how to get it depends on their respective creations.

At this time, Yunchen finally figured it out, the fire was in front of him, he didn't want to miss it, if he could get this thing, his strength would definitely soar, and in the future, he would also solve the matter of refining his own medicine.

However, how can this underground magma go down on its own?

This is the closest place to the fire, and the power of the fire is also the strongest.

"With such a strong flame power, I really don't know how long this flame has been burning here!"

Although he didn't see the tinder, Yunchen was sure that the tinder was below.

It stands to reason that Wucheng has only been established for a hundred years, and this Fire Cloud Cave is only a hundred years, and if such a flame power can be formed in a hundred years, this fire will definitely not be too bad.

Is it the middle grade of the human rank, or the top of the human rank?

Yunchen recognized the fire in the hands of Mu He and Lie Feilong, they were all beginner in the human rank, although Mu He's fire was stronger, but it was also cultivated for decades, far from reaching the level of the middle grade.

According to the time calculation, the terrifying high temperature formed here, this fire under the surface is at least a medium grade, and it is very likely to be a human rank.

As for the ground level fire Yunchen, he didn't dare to think about it, because such a high-intensity fire Yuan Dan realm powerhouse would fight for it, how could the city lord of Wucheng put it in this fire cloud cave to make an opportunity to leave it to the disciples of Wucheng.

There are many fires in this world, especially low-grade fires, but fires have one characteristic, that is, all fires are incompatible, even if the heaven-level fires want to fuse or devour human-level fires.

Tinder has its own uniqueness, and the result of the fusion of different fires is destruction.

Therefore, many people will cultivate their own fire after getting the fire, and use various fire attribute materials, including pure yang stone and other materials to cultivate their own fire, from the human level to the high level.

Or after encountering a high-grade fire, the original fire is discarded and used to pass it on to future generations.

Or a spark like the one in the Fire Cloud Cave is used as a reward for chance, and so on.

Therefore, the fire in this Fire Cloud Cave is definitely not a high-level fire, otherwise it would have been taken by someone a long time ago, how could it be his turn?

Thinking of this, Yunchen was a little worried, because he found that the mixed element fire he had condensed with the Mixed Element Technique was also a fire, would it conflict with the fire underground?

Although the mixed element fire is not a real fire, it can only be regarded as a pseudo fire, but it is also a fire, and the fire cannot be blended, so don't use it even if you get it at that time, isn't it fucked?

Moreover, his Mixed Yuan Flame was condensed by him with the Mixed Yuan Technique, which was impossible to throw away, unless he gave up cultivating the Mixed Yuan Technique.

Relative to the fire, not to mention the human level, even the heavenly level could not make him give up cultivating the Mixed Yuan Technique, this kind of anti-heaven technique of ten condensing ten mixed element seeds, no fire can replace it.

However, the mixed element fire in his body was extremely eager for the underground fire at this time, which made him wonder again......
