Above the Nine Secluded Yellow Spring, Du Fei sat cross-legged in the air, and the breath emanating from his body, if anyone could detect it at this moment, would definitely find that the passage of the world accompanied by his breath could be said to be stronger in minutes and seconds, and the change in this breath, although it only came from the cultivation of Dan Dao, was still breathtaking!

The strengthening of this kind of aura lasted for half a month, and then, the surging spiritual power hovering on the surface of Du Fei's body showed some signs of weakening.

In mid-air, when the last trace of spiritual power drilled into Du Fei's small world of eyebrows, his eyes, which had been closed for countless days and moons, also opened suddenly, and in those dark eyes, there was a glint of essence at this moment, and it quickly dissipated into nothingness.

"Click-"

Du Fei exhaled slowly, his hands were slightly clenched in mid-air, and he immediately felt that an extremely terrifying spiritual power wrapped up and down his body instantly roared out, and this feeling was like an ancient fierce beast lurking in Du Fei's body, suddenly waking up from his slumber.

"Not bad. Du Fei felt the change in his Dan Dao cultivation, and he could clearly feel that at this moment, he had completely integrated the four Heaven and Earth Yuan Dan into one, and from then on, he thought that these four Heaven and Earth Yuan Dan would have a new name - Reincarnation Ice Lei Dan!

And outside of here, the unprecedented sense of fullness of power above the spiritual power in the Dan Dao also made Du Fei can't help but breathe a sigh of relief in his heart.

"Master, your current Dan Dao cultivation should have a four-rank peak Dan Sect realm, if the opportunity is right, you will even be able to enter the half-step Dan Saint Realm soon, as long as you can stabilize your strength, master. And at that time, master, you are only one step away from the Dansheng realm!" Xiao Bai's figure flashed out, looking at Du Fei and speaking.

"So fast?" Hearing this, a look of surprise also appeared on Du Fei's face, although he knew that this time he would be fed back by the Heaven and Earth Yuan Dan, but even he couldn't imagine that he could make such amazing progress!

This kind of strength, not to mention the sealing realm, even if it is on the Xuanwu Continent, it can be regarded as extremely terrifying, right?

"It's not fast, originally master, you have four Heaven and Earth Yuan Dan in your body, at this moment, these four Heaven and Earth Yuan Dan are completely fused together, although it is not as good as the legendary Heaven and Earth Yuan Dan in the first place, but it should be almost the same as the second one! Xiaobai pouted.

Hearing this, Du Fei smiled, but he didn't care about the faint mockery in Xiaobai's words, he just nodded slightly, although this Dan Dao cultivation has taken a big step forward this time, but looking at the current situation, for the time being, Dan Dao cultivation should not be able to make much progress for himself, and it can reach the half-step Dan Saint Realm, which is considered the limit. And if you want to continue to make progress, you either have to find a place to concentrate on the origin power of the Heaven and Earth Yuan Dan, or you have to find another Heaven and Earth Yuan Dan to refine.

As soon as he thought of this, Du Fei had a slight headache, and he stopped thinking about it at the moment.

"But master, I suggest you don't worry about Dan Dao cultivation for the time being. Xiaobai suddenly said softly.

"What do you mean?" Du Fei frowned.

"This, if I'm not mistaken, the time limit for your Qiqi Soul Chasing Seal should also have arrived!" Xiao Bai was silent for a moment before he spoke softly.

"What!?"

Hearing this, Du Fei was not too surprised at the moment, but frowned slightly. Now that Du Fei's Dan Dao cultivation has just skyrocketed, the most important thing to do should be to find a place to cultivate and stabilize his cultivation.

But it's a pity that he doesn't have this time at the moment, at this moment, since the time limit for the Qiqi Soul Chasing Seal has arrived, then the energy contained in the Qiqi Soul Chasing Seal is probably about to seep out. Although it is said that due to the characteristics of the Qiqi Soul Chasing Seal, there should not be much problem in this process, but if this is really the case, the cultivation of his Danwu and Martial Arts will skyrocket, and if he can't stabilize it, I am afraid that in the end, he will damage his originally extremely stable foundation.

"Whew-"

As soon as he thought of this, Du Fei no longer thought about any superfluous time, but quickly sat down cross-legged, slowly waiting for the time to come.

"Boom-"

I don't know how long it took to cross my knees like this, and suddenly, the skull blood mark in the center of Du Fei's eyebrows shook slightly, and in the next moment, a blood-colored light instantly rose to the sky!

"Whew-"

These violent energies, the next moment they rushed out of Du Fei's body, were like waterfalls, swooping towards Du Fei's place from another direction.

"Reincarnation Spirit Pattern!"

Looking at this scene, Du Fei stretched out his right hand at the center of his eyebrows, and in an instant, he saw the black and white two-color reincarnation vortex floating on the surface of his body, and then assisted Du Fei to refine all these incomparably pure and violent energies.

"Whew-"

When the first blood-colored energy entered Du Fei's body, a feeling of water melting made Du Fei let out a long sigh. The energy contained in this Seventy-Seven Soul Chasing Seal has been lurking in Du Fei's body for a long time, and it has long been completely integrated with the breath in Du Fei's body, so if it is refined at this moment, there is no big problem.

A smile slowly emerged from the corners of Du Fei's mouth, and immediately, his eyes slowly closed, and then his hands posed out the mark of cultivation, and on the surface of his body, colorful light surged, which quickly incorporated those blood-colored energies into his body.

"Bang bang bang-"

And with these violent and pure energies entering his body, Du Fei's body also trembled violently, and the low sound of ringing continued to come out of his body.

You must know that the energy gathered in this Seven Seven Soul Chasing Seal is enough for people to ascend to the sky in one step, directly reach the peak of the four-rank Martial Sect realm, and even enter the half-step Martial Saint realm, the richness of these energies is a bit beyond imagination, if it weren't for Du Fei's physical strength being so strong that it is unimaginable, I'm afraid ordinary people wouldn't be able to withstand this kind of energy.

However, these energies are terrifying, but with the influx of energy, Du Fei can also clearly feel that wisps of extremely pure breath are constantly integrated into his limbs.

This kind of energy made him feel a faint sense of loss in his body after refining the ancient heavenly phoenix of the royal family that day, and he had a sense of calmness, which was just like the cells, bones, and muscles that had not been thoroughly strengthened that day, all of which were becoming more and more powerful and perfect at this time.

The colorful light is also all over Du Fei's body at this moment, and under the colorful light, a faint gray aura is also flowing, obviously, the Heavenly Phoenix Immortal Sutra and the Fortune Extinguishing Technique in Du Fei's body are all spontaneously operating at this time, and they begin to be continuously strengthened.

And with the influx of these energies, on the surface of Du Fei's body, another Heavenly Phoenix Light Pattern soon appeared, and then immediately after, a third ..... appeared

On that day, in Yinglongtai, Du Fei only condensed a heavenly phoenix light pattern, but unexpectedly, today he directly condensed two lines! The energy contained in the Qiqi Soul Chasing Seal is so rich that it is beyond Du Fei's imagination!

"If you refine everything, I don't know how far it can go!"

After Du Fei muttered a sigh in his heart, he continued to maintain a quiet cultivation state.

Time passed slowly again, but this time it was only after three days, Du Fei's closed eyes slowly opened, and after a long breath, Du Fei clearly felt that the energy that was surging and circulating in his body had all belonged to him at this moment!

And the Martial Dao Yuan Dan in the place of his own dantian qi sea has turned into the purest purple gold color at this moment!

"Four-rank peak martial arts realm!"

Almost instantly, Du Fei recognized his strength at the moment! Then a look of ecstasy appeared on his face.

After these two rounds of skyrocketing strength, that is to say, at this moment, Du Fei is not only a fourth-rank peak martial arts realm powerhouse, but also a fourth-rank peak Danzong realm powerhouse!

And after many years of cultivation of Danwu and Wu, Du Fei finally let the two forces in his body reach a relatively balanced state at the same time for the first time.

Moreover, with the fusion of these two forces, plus some other means, Du Fei was confident that under the saint-level powerhouse, there would definitely be no one who would be his opponent. Even if he is a powerhouse at the level of a half-step saint, he has the confidence to fight head-on!

"This Heavenly Phoenix Immortal Sutra seems to have been strengthened!"

Du Fei squinted and stared at the surface of his body, at this moment, there were three heavenly phoenix light patterns flickering on his body surface, and the other half appeared with a faint light, obviously, although Du Fei couldn't condense four heavenly phoenix light patterns at this moment, but the distance was not far away!

And after being strengthened again, this Heavenly Phoenix Immortal Sutra seems to make Du Fei's body contain more powerful power.

It seems that my luck this time is really good!
