"Duyang Saint Pill! What a Duyang Saint Pill!" Yi Nan was overjoyed, with this Nanyang Lihuo, he could refine the System Yang Shengdan, but the current Yi Nan would definitely not be able to ingest the slightest Nanyang Lihuo if he didn't control the power of the extreme yin!

If Yi Nan successfully refines the Duyang Saint Pill, then the moment Yi Nan steps into the Tianyang Realm, the Dan Fire can be born based on the Nanyang Lihuo, so Yi Nan's Dan Huo will directly surpass the geniuses of the same level, so if Yi Nan steps into the Tianyang Realm, then Yi Nan's combat power will increase at a terrifying speed.

The next moment Yi Nan did not hesitate at the slightest holding the Tianhan bead and directly submerged into the steps full of Nanyang from the fire, with Yi Nan stepping into the Nanyang from the fire The moment the jade coffin trembled slightly, the woman's closed eyes seemed to move at this time, if Yi Nan and Ao Long knew, it was estimated that they would be frightened, because if that kind of storage zài woke up, they might be killed directly, even the current heavenly core may not be able to stop it.

After all, the current Yi Nan has not really controlled the Heavenly Core, once Yi Nan controls the Heavenly Core, then Yi Nan's hole cards will be even more terrifying, so it will become more difficult or even impossible to kill Yi Nan.

However, the current Yi Nan has not yet entered the Origin Realm, so he cannot truly control the Heavenly Core.

Hum Nanyang Lihuo also surged rapidly with Yi Nan's entry, and it was also at this moment that the cold beads suddenly diffused with a cold power, which quickly enveloped Yi Nan, and suddenly Yi Nan sang a breath, and he quickly went down.

When Yi Nan walked towards Nanyang and left the fire, this volcanic ridge underwent a terrible change, the highest volcano shook rapidly, and endless black smoke spewed out, and in a short time the sky in this area turned black.

Some of the monks who passed by here in the distance were extremely surprised, they didn't know what was happening, but the black smoke continued to become more and more dense, and the golden sun above the sky was covered at this moment, and it didn't take long for this place to fall into darkness.

"What happened?" At this time, many monks who were far away in the Dan Sect were also shocked, especially Dan Yantian, at this time, he looked at the volcanic ridge in the southwest and frowned, at this time he was also a little worried, he intuitively told him that the change in the volcanic ridge was caused by the three of Yi Nan after they entered.

"Did that kid discover the Extreme Yang Fire?" At this time, Dan Yantian could not hide his excitement, but there was still a strong look of worry in his eyes. After all, the Extreme Yang Fire is difficult for him to compete with even now, let alone Yi Nan.

"I don't know if that kid found Tianhanzhu?" looked at Tianyu Dan Yantian in the distance, and said helplessly.

At this moment, Jin Xing and Beida Lang slowly opened their eyes, and they looked at the sea of fire slurry below suspiciously, and at this moment, they suddenly set off a terrible fire, and the continuous slapping on the shore made a roar.

"What about Brother Nan?" two flames suddenly shot out of Beida Lang's eyes who woke up, and the next moment Jin Xing did the same, they all looked around suspiciously, but they didn't see Yi Nan's figure.

"Brother Nan!" Beida Lang let out a low roar, but after a while, he didn't see Yi Nan's response.

"Damn, what can I do about this?" Jin Xing said anxiously.

"What are you worried about, Nan Gefu has a big life, he won't die here. Beida Lang shouted angrily.

Jin Xing didn't speak, and the two of them quickly walked towards the depths along this sea of magma, but they did not step into this sea of magma, so it was absolutely impossible to find Yi Nan, at this time, Yi Nan crossed Nanyang about a kilometer away from the fire, and the Tianhan Bead in his hand also changed from the size of the previous fist to the size of a thumb, looking at the ground close at hand, Yi Nan directly roared and rushed out.

As Yi Nan stepped on the ground, a terrifying yin force instantly rushed directly into Yi Nan's calf from the soles of Yi Nan's feet, and Yi Nan's whole person froze in an instant, but the unquenchable fire at Yi Nan's dantian surged in an instant, rapidly restoring Yi Nan's stiff state.

"What is this?"

At this time, Yi Nan looked at his feet suspiciously, above his head at this time, the endless Nanyang was surging from the fire but it was not sinking in the slightest, but when Yi Nan looked at his feet, his expression changed violently, and at this time, the endless black air flow below his knees surged.

"This is the power of the Extreme Yin?" said Yi Nan, who didn't seem to feel anything terrible.

"It should be, otherwise, it will definitely not be able to carry the fire of the extreme yang, and the fire of the south yang will leave the fire. Ao Long said in a deep voice.

Yi Nan nodded slightly, and then he sat down directly, and suddenly his expression changed suddenly, and the moment he sat down, the black air flow was directly suspended in his neck, and at this moment he suddenly felt a terrifying yin force rushing directly into his body.

If it weren't for the unquenchable fire in his dantian, maybe he would have become a dead man by now.

The power of extreme yin freezes the soul, and the power of extreme cold freezes the body. Of course, the power of extreme yin can also temper the physical body, but it cannot be compared to the forging of the physical body by the power of the cold. Of course, the current Yi Nan physical body has stepped into the Tianyang Realm, and he doesn't need the forging of Yin Power here, and now he just wants to let his cultivation step into a more powerful realm.

"Extreme Yin Power!

Yi Nan didn't waste time with Lang, although it didn't take long for him to step into the sixfold of the Earth-Netherworld, but now that such an opportunity allowed him to break through, he would not refuse, after all, when Yi Nan stepped into the six-fold of the Earth-Netherworld, he had experienced the penance of the Ten Thousand Blood Pool.

Now this extreme yin power is more suitable for Yi Nan's penance!

The ten changes of Qiankun suddenly moved, and in an instant, a three-layer purple-black vortex appeared on Yi Nan's head, and as this purple-black vortex appeared, the space within a radius of about a thousand miles suddenly trembled slightly, and at the same time, the power of the extreme yin here also rapidly converged towards Yi Nan.

The inextinguishable fire of sneering quickly supported Yi Nan, preventing Yi Nan's soul power from being frozen and dissipating under the power of this extreme yin, and his soul sea was filled with a rich three-color immortal fire at this moment, and with the power of the extreme yin entering the body, Yi Nan also felt a desire for his supreme dantian.

The rapid surge of the natural dantian and the earthly dantian continued to devour the power of the extreme yin that entered the body, so Yi Nan also let out a low roar at this moment, and the voice echoed rapidly in this quiet space, but there was no response.

Day by day began to pass, and on the third day, Yi Nan's body trembled violently, and at this moment, a seventh black yin power circle suddenly appeared on his body surface, which also represented Yi Nan's cultivation stepping into the sevenfold earth yin realm.

In just three days, Yi Nan rushed into the sevenfold of the Earth's Yin Realm in the power of this extreme yin, and if Yi Nan stepped into the sevenfold of the Earth's Yin Realm within three months, once he returned to Danmen, it would cause a terrible turmoil.

On the twelfth day, the entire Extreme Yin Land trembled violently, and at this moment Yi Nan let out an even more terrifying roar, at this moment, Yi Nan's eyes were dripping with black blood droplets, and his hair was slowly turning from blood to black.

At this moment, Yi Nan trembled, absorbing more and more extreme yin power in this short period of time is a pain for Yi Nan, this pain hurts the soul, at this time, the unquenchable fire in Yi Nan's soul sea is shaking rapidly, but at this time, Yi Nan's soul sea is rapidly appearing golden light, although the dragon clan's soul circle is broken, but it is not easy to break through this soul circle, even if it is the power of extreme yin.

But each impact also caused Yi Nan a lot of pain, and his head seemed to explode.

"Break it for me!"

On this day, Yi Nan roared, and with the moment he stepped into the land of extreme yin for fifteen days, Yi Nan's body trembled violently, and in Yi Nan's body, an eighth yin vein appeared in his supreme dantian, and with the appearance of this yin vein, it was rapidly condensed in half an hour.

This is a terrible thing, it takes at least three months for ordinary monks to condense a Yin Vein, but Yi Nan in this Extreme Yin Land can complete it in the blink of an eye, because only a condensed Yin Vein can impact the next realm.

At this moment, Yi Nan quickly stopped the entry of the power of the extreme yin around him, and he got up directly, at this time, he clenched his fist violently, and immediately went directly towards the fire bombardment of Nanyang, and now Yi Nan condensed the power of the extreme yin with the help of the ten changes of Qiankun, so that Yi Nan controlled the power of the extreme yin, and he wanted to try.

There was a loud bang, and Nanyang Lihuo above his head trembled violently, but at this moment, Yi Nan was not satisfied, he directly inserted one hand into this Nanyang Lihuo, and in an instant, Yi Nan's palm quickly showed signs of drying, which frightened Yi Nan and quickly withdrew.

"If you want to control the power of the extreme yin, the strongest is the peak of the earth yin realm, of course, the so-called extreme yin power is also a title, this Nanyang Lihuo should be much stronger than the power of this extreme yin, but this extreme yin here was born from the fire of the extreme yang, so he will not be devoured, but outsiders are different. ”

"I understand what that means, I know what to do. Yi Nan nodded.

Then the Tianhan Bead in his hand appeared again, and the thumb-sized Tianhan Bead melted rapidly, but at the last moment of ablation, Yi Nan grabbed a handful of Nanyang Lihuo and pressed it directly on his abdomen, and in an instant, Yi Nan's whole person trembled violently, and a blood hole appeared in his abdomen in an instant, but the next moment Yi Nan directly pressed a handful of Nanyang Lihuo directly on his three-color unquenchable fire.

In an instant, the unquenchable fire trembled rapidly, but in this fear, there was an inexplicable excitement.

"Lian!"

Yi Nan let out a low roar, a purple-black vortex directly appeared in his body, and in an instant, it directly wrapped his own inextinguishable fire, as well as that Nanyang Lihuo, Yi Nan wanted to assimilate his own inextinguishable fire, this Nanyang Lihuo, so that he could do what he wanted to do, and only in this way could he really come and go freely in this Nanyang Lihuo!
