After thousands of years of reproduction, the entire continent is gradually covered by lush towering ancient forests, and human stations are scattered in all directions like scattered islands.

The Cloud Breaking Sect, since it was destroyed more than ten years ago, the entire sect is now overgrown with weeds, some sparse planted trees have been drilled out of the soil, looking at it from a distance, it looks more like a large wasteland, like this, after decades, I am afraid that there will be no trace of human activity anymore.

In a barren forest tens of thousands of miles away from the Cloud Clearing Sect, on the surface, this place is no different from other places, but if someone accidentally steps into it, they will find that there is another world here.

Inside and outside the formation, it is like two worlds.

The dilapidated hall is no different from twenty years ago, but if you look closely, you will find that it has been renovated and looks like an ordinary farmhouse.

The figure of the green robe was motionless, and around the main hall, the spiritual power of heaven and earth was like smoke and wisps of smoke all year round.

At this moment, at Kong Laosan's dantian, a golden pill about the size of a dragon's eye, full of emerald color, was quietly suspended, and around the pill, there was a thin layer of cyan mist like smoke, with each exhalation, these mist faintly converged above the pill, and in the mist, there was a faint trace of spiritual fluctuations.

"Dan Qi Transformation!"

If some experienced seniors were here, they would definitely recognize Kong Laosan's situation at this time, "Dan Qi is reborn, Dan Fire is condensed!"

Building the foundation and knotting Dan, one heaven and one earth.

Of course, once the spiritual power in the cultivator's body reaches the realm of the Dan, the spiritual power in the cultivator's body will increase exponentially, swallowing a large amount of spiritual power and stabilizing itself.

After reaching the knot, the spiritual power of heaven and earth is like a river, and then trying to rely on the inherent meridians in the body to wash and refine over and over again is undoubtedly a very stupid approach, so condensing the Dan fire has become a necessary way for the cultivator to condense the Dan.

The external spiritual power that is scorched and swallowed by the Dan Fire is initially refined, and then further purified and refined through the meridians, and directly fused into itself, and the efficiency is undoubtedly much higher.

At this moment, Kong Laosan's state is like this, with the condensation of the Dan Qi above the Jindan, the fog that was originally like smoke and hazy looks like a hazy fog gradually condensed, clustered into a flame about the size of a finger cover, after a long time, when all the fog gathered here, in the center, a faint trace of divine soul power fluctuated out, this divine soul power was like a little spark, and the mist was ignited in an instant.

Danhuo, also known as "natal fire", is a kind of natal fire formed by the essence of the cultivator, with the improvement of cultivation, the power of the danhuo will become stronger and stronger, can be used against the enemy, alchemy, refining tools, etc., all kinds of wonderful uses.

However, at the moment when Kong Laosan's wisp of Dan Fire had just condensed and formed, a sudden change occurred.

Originally, it was quietly suspended above the dantian, dim, and the soybean-like extreme flame seemed to sense something, and suddenly rioted.

A little yellow light reveals the pure power of the sun, in the center, a faint red "乂" character text appears and disappears from time to time, but in just a few breaths, the power of the yang penetrates, with a slight sound like a bubble bursting, the "Yi" character text burst for a moment, and is instantly burned into nothingness, at the same time, the soybean-sized fire swarms towards the Dan fire that has just been condensed and formed.

"Buzz ......"

Kong Laosan only felt the dantian tremble, and a scorching extreme yang power evaporated from the dantian, instantly spreading all over the limbs, the whole body instantly became blood red, blood beads seeped out from the pores around the body, and the original cyan robe seemed to be scorched, and the folds were attached to the body.

At this moment, Kong Laosan's whole person was like a red-hot prawn, holding his abdomen with both hands, twisting on the ground in extreme pain, constantly struggling, and at the dantian, two flames with little difference in volume seemed to melt into one, one green and one yellow, intertwined with each other, and distinct.

The Extreme True Fire is domineering and blazing, revealing the power of the pure extreme yang, trying to fuse this cyan Dan fire that has just been generated, but the cyan flame is relatively weak, although it is trying its best to resist the erosion of the other party, but they are not at the same level as each other, if it is not for the Jin Dan, with the endless aura support of the dantian, I am afraid that it will be swallowed by this extreme fire in an instant.

It took three days for Kong Laosan to wake up from his coma......

In the thatched hut, Kong Laosan, who had just woken up, had a trace of confusion in his eyes, looked at the whole body of Clean and Autumn, his old face was red, and he hurriedly took out a brand-new cyan robe from the storage bag that fell on the side, and after dressing up, he silently recalled what happened before.

The Extreme Flame broke through the seal and wanted to devour the Natal Pill Fire that had just been condensed and formed in the body, and the two fused, and a terrifying scorching power was born from the dantian, burning the entire body red, and even the consciousness was scorched by this supreme yang power.

Just when he felt that the whole person was about to be burned to ashes, a large amount of Xuanyin Qi that was originally hidden in his meridians, flesh, and acupoints automatically gathered into the dantian......

Thinking of this, Kong Laosan's eyes moved slightly, his mind was introverted, and he went to explore the body, but he saw that below the mouth of the heart, at the Jiang Palace, the position of the dantian in the body, a little soybean-sized flame was burning quietly, the fire heart was blue, and a layer of pale yellow flames was wrapped outside, and he silently felt it, and a true fire power of the most masculine and rigid spread out from it, and this power was domineering and abnormal, far beyond the power of the Dan fire formed by ordinary Jindan cultivators.

However, when Kong Laosan noticed the scene in the lower dantian, the whole person was stunned on the spot, originally ten years of knotting, plus ten years of retreat, it was worth the size of a dragon's eye, but at this time, it was actually half the size of a fist, this kind of appearance, it was almost the same as those ancestors who had been knotting for hundreds of years, and even the realm of the middle stage of knotting was not far away.

In just a few days, the strength has skyrocketed to such a situation, which makes Kong Laosan have an unreal feeling, continue to investigate, Kong Laosan is more and more frightened, in addition to the strength realm has skyrocketed a lot, the bones, meridians, internal organs, and physical body seem to have been transformed by some kind of force, more than several times stronger than before the retreat, at this moment Kong Laosan even has a feeling that just by relying on the power of the body, he can crush the Jindan cultivators of the same realm.

The Xuanyin Body, as one of the nine best furnaces in the Immortal Cultivation Realm, brings benefits to cultivators not as a short-term ascension to the realm, but as a long-term effort to improve the physique and Mianze Daoji.

At the beginning, he and Ke Zhen'er not only solved the hidden dangers in the other party's body, but also the benefits to themselves were unimaginable, and now, they indirectly saved their lives.

Thinking of this, the corners of Kong Laosan's mouth hooked, and the shadow of the beautiful woman flashed unconsciously in his mind......

After condensing the Danhuo, you may be able to try the refining of the natal weapon next.

Thinking of the natal magic weapon, Kong Laosan automatically thought of the refining method called the "Evil Slashing" magic sword, but when he thought of those legendary materials, he couldn't help but have a secret headache.

Sighing, Kong Laosan shook his head a little annoyed and walked out of the main hall.

At this moment, three rays of light pierced the void, and Kong Laosan didn't care about it, and his subconscious thoughts were swept away, but he was slightly stunned.

Judging from the way they dressed, the three people in front of them seemed to be cultivators of a certain sect, two men and one woman, except for the woman who was still in the early stage of foundation building, the other two had reached the middle stage of foundation building, and they seemed to be being chased by something, and they were running away with a panicked face at the moment.

"Could it be that a certain sect has encountered another beast tide?"

I thought to myself, but I didn't plan to be nosy.

However, Kong Laosan didn't have such thoughts, but the three people in front of him had already set their eyes on Kong Laosan, seeing that Kong Laosan seemed to be alone, the two cultivators who had reached the middle stage of foundation building glanced at each other, and instantly understood each other's meaning, and galloped in the direction of Kong Laosan without thinking about it, the woman on the side seemed to be a little unbearable, opened her mouth, but seemed to think of something, just pursed her lips, and fled in this direction with the two.

Seeing this, Kong Laosan subconsciously frowned, put his hands behind his back, and remained motionless.
