Time slowly passed through the space in the depths of the magma ocean, and in the center of the formation of this space, an emaciated figure sat quietly cross-legged, and the true qi continued to swirl out, slowly refining the ancient heavenly phoenix essence blood suspended in front of him, and vaguely, this space had the sound of wind and thunder constantly lingering.

With the passage of time, these ancient Heavenly Phoenix essence blood were constantly refined, and after the last drop was refined by Du Fei, his originally closed eyes suddenly opened, and after frowning slightly for a moment, he muttered to himself: "Refining this essence blood has made the Heavenly Phoenix Immortal Sutra close to Dacheng, but I can't cultivate the colorful flames that that guy brings." ”

Speaking of this, Du Fei also shook his head slightly, the power of the colorful flames cast by the ancient heavenly phoenix that day seemed to be a little stronger than the wind and thunder, originally Du Fei thought that if he refined its essence blood, he should also be able to promote the evolution of the Heavenly Phoenix Immortal Sutra, but now it seems that this is not the talent of the ancient Tianfeng clan, but I don't know where the ancient Tianfeng learned it.

"That's it, anyway, the Heavenly Phoenix Immortal Immortal Sutra is now close to Dacheng, and its power is much stronger than before, and besides, I'm just a little bit away from the fourth-grade low-level martial sect realm now?"

At the same time that Du Fei was refining the ancient Tianfeng essence blood, Du Fei's strength was also constantly rising, this time to refine the ancient Tianfeng essence blood, Du Fei calculated about it, it should have taken more than a month, this time is not short, and the ancient Tianfeng essence blood obviously contains extremely terrifying energy, so it is extremely normal to let yourself reach this level.

It's just that just refining the ancient Heavenly Phoenix essence blood to reach this level, Du Fei was not satisfied, originally he wanted to use the opportunity of refining the ancient Heavenly Phoenix essence blood to allow himself to reach the fourth-grade low-level martial sect realm.

Du Fei only understood after the battle with the Ancient Heavenly Phoenix that the strength of the powerhouses of the Four-Rank Martial Sect Realm, not to mention anything else, in terms of true qi alone, ordinary powerhouses could not compete with them at all. If it weren't for the fact that the ancient Tianfeng was seriously injured and disappeared because of the Nirvana Tribulation, and had to borrow Gu Lingzheng's body, then Du Fei's group wanted to take him down that day, which was tantamount to a fool's dream!

Moreover, Du Fei is in the sealed realm at the moment. Although it was only a little more than a month later, Du Fei could see that because of the extremely limited cultivation resources in the sealed realm, the environment of this sealed realm could be said to be extremely cruel, and he had killed that Leng Wusheng and offended the relationship between the Shadow Demon Sect, if he didn't have enough strength, then let alone finding a chance to leave the sealed realm, whether he could save his life was still a matter of two words!

Therefore, at this best opportunity, Du Fei wanted to raise his strength to the fourth-rank low-level martial sect realm! In that case, relying on his physical strength and Danwu dual cultivation ability, he should be able to at least fight with the fourth-rank middle-level martial sect realm powerhouse, and even the fourth-grade high-level martial sect realm powerhouse would be able to try it himself.

Therefore, being able to break through to the fourth-grade low-level martial sect realm is the most important thing!

Of course, Du Fei also understands the difficulty of breaking through to the fourth-rank low-level martial sect realm, he just entered the fifth-grade peak martial sect realm more than a month ago, it can be said that the foundation has not been laid yet, and it is impossible to make a breakthrough naturally, and if you want to continue to break through, you need to rely on a little fierce medicine!

As soon as he thought of this, Du Fei shook his palm, and the ring he had taken from Zhou Qing that day appeared in his palm.

The palm of his hand casually brushed over the Rong Ring, and suddenly he saw a pile of dense demon crystals instantly falling in front of Du Fei, looking at these demon crystals, Du Fei couldn't help grinning.

Although these demon crystals are not Yanzong Dan, the energy contained in them is definitely not to be underestimated, plus there is an ancient formation here at this moment, so if you want to improve your strength, it doesn't seem to be too much of a problem!

As soon as he thought of this, Du Fei no longer wasted time, but the imprints of his hands changed, and in an instant, extremely terrifying fluctuations instantly spread out in all directions, covering those demon crystals under Du Fei's true qi control, and then the imprints in Du Fei's hands changed again.

"Buzz—"

With Du Fei's movements, in an instant, he saw that there were extremely terrifying various energies on the demon crystal that instantly shot out, and then Du Fei's movements were constantly poured into Du Fei's body.

Du Fei's body trembled slightly, and the Heavenly Phoenix Immortal Sutra in his body was running rapidly, and only this exercise could make Du Fei forcibly accept this rich energy.

And with the infusion of this rich energy, Du Fei's breath slowly climbed again, although the speed of this climb was not very fast, but it was a real increase.

The space in the magma ocean fell into silence again, only the extremely dense energy in the field continued to swim, and then as if it had been guided by some kind of guidance, it continued to pour into Du Fei's body.

Time passed slowly again in the midst of cultivation, and in the blink of an eye, half a month passed again.

"Boom-"

When the time of half a month came, the figure that was originally sitting quietly trembled slightly, and at this moment his aura had become extremely strong, and there was no difference between him and the so-called fourth-grade low-level martial arts realm powerhouse!

However, this is not really a fourth-grade low-level martial arts realm powerhouse!

If he wants to become a fourth-grade low-level martial arts realm powerhouse, what Du Fei needs to do is very simple, that is, to survive the sect breaking tribulation again!

"Time, it seems to be almost there!"

Du Fei muttered, and then the soles of his feet suddenly stepped on the ground, but his entire body was already shooting out quickly upwards!

............

Beyond the crater, at the edge of the basin, in this uninhabited place at this moment, there are tents standing, many of them flickering, and faintly bursts of sound come out.

These figures are naturally the stewards who stayed here before, and now in this necromantic abyss, with the end of the ancient Tianfeng dispute, eight or nine out of ten people from all sides have died, and the remaining forces are also retreating rapidly, obviously not wanting to provoke Du Fei, the evil star, and only the butler has not left for some reason.

Guan Ting stood at the edge of the basin, her eyes gently staring at the crater in front of her, at this moment, the aura on this little girl's body was extremely terrifying, and it was obviously infinitely close to the realm of the fourth-grade low-level martial sect! Moreover, the feeling of sickness in her body had disappeared, and was replaced by a youthful vitality.

Obviously, after refining the ancient Heavenly Phoenix Demon Crystal, this little girl also got a lot of benefits. It's just that she doesn't dare to impact the fourth-grade low-level martial arts realm, and it is estimated that she will only try it when the elders are around!

Just an ancient Heavenly Phoenix Demon Crystal has made this little girl's strength skyrocket to such a point, no wonder countless people fought to the death for this thing before!

"Don't worry, even you, this little girl, can completely refine the Ancient Heavenly Phoenix Demon Crystal, it's just a few drops of Ancient Heavenly Phoenix Essence Blood, can he still fail?"

And just when Guan Ting was stunned, Guan Yan suddenly walked to her side, also looked at the crater and said lightly.

When Guan Ting heard this, she also nodded slightly, and then said with some hesitation: "However, Brother Du Fei has been down for a month and a half......"

"At this time, let's wait quietly, even if you don't feel at ease, it is impossible for us to go down, because no one knows what that guy is doing underneath......" Guan Yan sighed, "However, if my guess is right, this guy is afraid that with the help of the ancient Heavenly Phoenix essence blood, he will directly impact the fourth-grade low-level Martial Sect Realm! ”

"Hmm... Then wait and see. Hearing this, Guan Ting hesitated for a moment before nodding lightly and speaking.

"Huh!?"

Just when Guan Yan wanted to say something, suddenly, her brows were furrowed, and then her fierce eyes froze, and she grabbed Guan Ting's arm, and in an instant, the figures of the two instantly retreated to the rear.

"Everyone!

Between retreating, Guan Yan also gave the order quickly, accompanied by his voice, although many people didn't know what was happening, but they still retreated as quickly as her.

"Bang-"

At the moment when the butler's man quickly retreated, suddenly, he saw that above the originally calm crater, there was a magma pillar that suddenly rose to the sky, and then, these magma were pouring down in all directions, and almost at the same time, a figure appeared in mid-air in an instant.

"Brother Du Fei!" Guan Ting was overjoyed when she saw this familiar figure, and she wanted to meet it.

However, as soon as her body moved, Guan Yan grabbed Guan Ting's wrist, shook her head slightly, and said, "At this time, it's better for you not to get close to your big brother Du Fei, otherwise, even I won't be able to protect you!"

"Why?" Guan Ting's face was stunned, as if she couldn't understand it.

"Is this so hard to guess?" Hearing this, Guan Yan also shook her head speechlessly, then stretched out her hand and pointed to the sky, and said lightly, "Look, what is there!"

Hearing this, Guan Ting's gaze quickly swept over, and then she clearly saw that above Du Fei's head, I don't know when, the thick clouds began to converge continuously, and among the clouds, there was an extremely terrifying thunder dragon constantly swimming......

"Breaking the Sect!"

Guan Ting came out silently, and her little face froze instantly!Brother Du Fei is so fast, he is about to break the sect tribulation again!?
