The biggest difference between the Yuan Dan Realm and the Weather Realm is the gap in strength, the gap between the strength and the Yuan Force is as insurmountable as the gap between heaven and earth, because of this, the strong people of the Yuan Dan Realm have natural restraint in the face of the weather realm cultivators, unless they have such a domineering strength as Yu Feng, otherwise they will only be completely abused.

The chaotic cave is full of rubble, potholes, filled with cold air currents, and the sound of water droplets dripping on the stones from time to time echoes in the cave, extremely harsh!

In another corner of the cave, the power has already climbed to the peak of the weather realm, and the energy particles are not much under this consumption, and it seems that he also feels that the situation is not good, Yu Feng's solemn face can't help but sweat a little more, and his lips are tightly closed.

The silence was about three hours, and suddenly the whole cave shook again, and the violent shaking made the rocks on the surrounding stone walls fall one after another, like rain, unconsciously, looking for the root of the vibration is Yu Feng in the knees, the energy particles have already been refined, and finally at the last moment, Yu Feng ushered in the opportunity to break through.

The whistling air flow around suddenly became fierce, like a knife and an arrow, scraping over the stone wall and leaving a shallow white mark, whistling by, and instantly Yu Feng was in the midst of that fierce energy storm, allowing the storm to invade, but the figure sitting cross-legged below was towering and motionless.

"Huh?"

A faint luster enveloped Yu Feng at a speed that was previously visible to the naked eye, and a faint golden light filled every pore of Yu Feng, and a soft feeling swept in.

"Hiss~~~!"

gasped, and in an instant, the surrounding airflow rushed into Yu Feng's body, and the blood vessels that communicated all parts of the body were spasmodic and twisted, and the strong pain made Yu Feng frown, and he couldn't help but scream.

"Do you still want to run?

As soon as his mind moved, all the power in Yu Feng's body burst out, blocking the air flow scattered in his body, and all of them concentrated in the dantian, the infinite air flow swallowed and condensed, and the huge energy swirled in a swirling nest, under the fusion and collision of what kind of power, even the original power in Yu Feng's body was sucked into it, and the power in the body became uncontrollable, and it became one!

The feeling of exhaustion came to his brain, sweating like rain, and in a daze, Yu Feng's whole person became chaotic, and he seemed to gradually come into contact with a completely unfamiliar power.

"Bang~!"

A vigorous explosion of the sound of the explosion suddenly spread, under the detonation of which force, the ground around Yu Feng was scraped three feet apart, and suddenly opened his eyes, and a spirit burst out, sharp like a sword, which made people throb their souls.

"Is this Yuan Li?"

Clenched his fists, the corners of his mouth unconsciously outlined a trace of arc, and while rising, he secretly felt the surging power in his body, and a golden Yuan Dan in his body was quietly suspended around his lower abdomen, and that was the sign of the Yuan Dan realm powerhouse - Yuan Dan, which is the source of the strength of the Yuan Dan athletic powerhouse, carefully felt the power within the Yuan Dan, and in an instant, Rao is Yu Feng's heart couldn't help twitching a few points, the strength of this power is not comparable to the strength of the weather realm cultivation at all.

It is precisely because of this that stepping into the Yuan Dan realm can only be regarded as entering the threshold of cultivation, however, but this simple threshold has made countless strong people unable to touch it for the rest of their lives.

Changed out of the tattered and sour clothes, stood up, and looked at the dilapidated stone walls around him, which had long been unrecognizable, although the tomb was strange and abnormal, and even the danger in it was far beyond his ability to bear, fortunately, there was Aoyun, otherwise, there was a chance that his life would be left here.

Although there are no precious spiritual weapons, martial arts and the like, but breaking through to the Yuan Dan realm harvest is already quite satisfactory for Yu Feng, after all, according to his own estimate, if he is lucky, it will probably take at least half a year to break through to this realm, not including some of these unfavorable factors, and now it is so light to break through to this realm that countless strong people yearn for, how can he not be happy?

Not only that, but the experience of many powerful forces in this ancient tomb mansion also made Yu Feng's slightly impetuous mentality even more silent, and every time it came to the moment of life and death, he couldn't help but find that he was so small, so small that the other party could wipe you out at will, and all you could do was wait for death!

"Whew~!"

Packing up his feelings, he took a deep breath, tidied up his robe, looked at the narrow exit, and calculated that it had been about eight days, so long as he walked out of Evil Moon Mountain, this level would be passed.

"I can't imagine that so much time has passed before I know it!"

Stretching his waist, Yu Feng couldn't help muttering to himself, the "crackling" sound of stretching his muscles and bones was extremely crisp, and the next moment the afterimage flashed, floating and slightly blind, connecting the ground.

The broken cave mouth hesitated, and the aura in the entire cave disappeared with the disappearance of the undead corpse, and then lost the deterrence of the demon beast, three hours later, Yu Feng, who was always full of darkness in front of him, suddenly stabbed a white light, and the fresh air couldn't help but make Yu Feng, who was corroded by the dirty air in this cave, greedily sucked a few mouthfuls, and the mood became more and more happy, but this good mood did not last long, that is, it was found that the moonless violent bear, and the thousand illusion white worms, and of course, the behemoth on the periphery - iron-scaled crocodile!

"Damn, these brutes didn't leave!"

scolded angrily, looking at these beasts who surrounded the cave Yu Feng was actually angry, and the people who were tortured by this group of beasts before were also quite wolf, but the mountains did not turn around, and now Yu Feng, who had advanced to the Yuan Dan Realm, was not stunned at all in the face of these beasts again, and was worried that there was nothing to practice and give full play to his strength, since these beasts insisted on sending them to death, then he didn't mind giving them a ride.

The figure did not stop, the thunder abyss battle sword came out, the yuan force roared, like a flash flying out through the space, the blade rubbed the space, split, the eyes were solemn, and the thunder arc summoned before also turned into a slender thunder snake at this moment, scattering in all directions, covering the entire sword blade.

"Roar~~!"

The roar shook the sky, and when he smelled Yu Feng's scent, the silent demon beast group suddenly went crazy, glaring at the crimson crazy eyes, opening his bloody mouth, and Sen Sen's fangs even dripped mucus, rushing towards Yu Feng like crazy, and at the same time, the starry light rose like a star curtain hanging from the sky, like a light net flashing with a glittering luster towards Yu Feng's mask.

"Gollum, Gollum~!"

The iron scales surged with a jet-black sheen in the sunlight, revealing a powerful defensive force, and every turbulence of the huge body made the space tremble.

The huge beast pupil locked onto Yu Feng, waved the heavy giant tail, and the space was painful, and a huge black light and shadow swept in his eyes, shaking the space, and the rapid whistling sound pierced the eardrum.

The corners of his mouth hooked a strange arc, snorted coldly, and the next moment the Yuan Force sprayed like a tide, instantly stirring in all directions, the power contained in the Yuan Force surprised De Yufeng, and he was not afraid of the beast at all. "Sonorous ~!" The thunder light shone, a sword and the giant tail collided together, sending out a series of golden sparks, cleansing out the aftermath of energy like substance, diffusing in all directions, not retreating but advancing, the soles of his feet slammed a step forward, with the help of the giant tail, he instantly came to the huge head of the iron-scaled crocodile, held the Lei Yuan sword with both hands, snorted angrily, and cut out the sky in the next moment.

Dao Dao's fierce sword qi exploded, feeling the powerful power, the iron-scaled crocodile's eyes also had endless fear in it, and he wanted to escape, but his huge body was a drag at the moment, compared to Yu Feng's speed, it was extremely clumsy, a breath of death was permeated, and the beast's eyes were full of fear.

"Boom~!"

When the blade landed on the head of the iron-scaled crocodile, in an instant, the black scales that came into contact instantly split in half, and the bubbling blood continued to gush outward like a fountain, and the body moved, but the beast known for its defensive power was completely defeated under the hard-to-face battle with Yu Feng, his eyes were scattered, and his eyes widened, I am afraid that what he didn't imagine was that the guy in front of him had only disappeared for a few days, but the growth of his strength was so fast, you must know that even in the face of ordinary Yuan Dan realm cultivators, it was more than enough to deal with the defense of the iron-scaled crocodile！

But in the face of Yu Feng, it was extremely vulnerable. "Click~!" The figure stood and looked at the iron-scaled crocodile in front of him, and a crisp sound was transmitted with a "click", and it split in half in an instant, and the clear chopping marks were extremely neat, and it seemed that even the cells inside were evenly split in half.

Seeing this, the originally fierce Moonless Storm Bear and the two major demon beast groups of Thousand Illusion White Worms were also shocked, a demon beast as strong as the Iron Scale Crocodile was so vulnerable in front of Yu Feng this time, and they were afraid that the result would not be much better. "I've been chasing Lao Tzu for so long, now let you also taste the taste of wolf bèi~!" Looking at the chaotic demon beast group, Yu Feng appeared with a bloodthirsty smile, and the next moment, his face suddenly became sharp, locking the Thousand Illusion White Worm, the sword blade cut the space, and in an instant, dozens of thunderbolts of sword slashed the sky towards the direction of the Thousand Illusion White Worm. "Squeak~!" The powerful power made these beasts instinctively feel fear, and the harsh sound was extremely sharp, and they scattered in all directions, but the sword slash speed was extremely fast, and there were still many thousand phantom white insects swallowed up by the sword qi, and where the sword slash passed, large pieces of white insect corpses were spread all over the ground, and the sound of clattering was like rain. "Hey~~!" watched the Thousand Illusion White Worm Wolf fade away, his eyes turned away, and finally landed on the big man.
