"Boom, boom—"

The thunderclouds in the sky seemed to be enraged by Du Fei's arrogance, and between the rolling clouds, the thunder became stronger and stronger, and they continued to roar down, fiercely beckoning towards the place where Du Fei's body was.

"Bang bang bang-"

In the face of such an increasingly powerful Nine Heavens Thunder, Du Fei's face still did not change in the slightest, he just stepped on the soles of his feet, and suddenly a white light appeared on his body!

"Wu Zonghuan!

With the appearance of Wu Zonghuan, the clouds that had been rolling in the sky suddenly appeared an extremely short silence, as if someone had choked his neck, which was extremely strange.

And Du Fei also raised his head and stared at the sky, and suddenly, he had a strange feeling, as if he had done something wrong at this moment.

Xiao Bai, who was originally squinting at Du Fei, also changed his expression at this moment, he looked up at the sky, and suddenly saw a hole like a whirlpool suddenly appeared in the middle of the thick dark clouds in the sky, and in the hole, there was a faint layer of thick clouds diffusing out!

"It's ...... Double Breaker!?"

Looking at this scene, Xiao Bai's pupils shrank suddenly, obviously he didn't expect that there would be a double sect breaking tribulation! That is to say, at this moment, the power of this breaking sect tribulation will skyrocket exponentially! And at the same time, because of the relationship between the double breaking sect tribulation, Du Fei's original chance of succeeding in crossing the tribulation has also dropped to five or five.

You must know that generally speaking, every time you are impacted and promoted, there will only be one Sect Breaker, and the reason why there will be a double Sect Breaker is generally someone to help, or the impactor has the strength to advance twice at the same time. Obviously, Du Fei did not help, so the biggest possibility is because he has the strength to advance twice in a row.

"Or is it the influence of that Martial Sect Ring?" Xiao Bai squinted his eyes and thought, but after a while, he gave up investigating the reason, because no matter what, the most important thing at this moment was that Du Fei was able to succeed in the tribulation!

"Boom, boom—"

It's just that after stopping for a moment, the Nine Heavens Thunder in the sky fell wildly again, but this time, the power of these thunderbolts increased several times, even with the Martial Sect Ring Protective Body, Du Fei's body was constantly trembling. It's just that under this kind of bombardment, Du Fei also clearly felt that the true qi in his body was undergoing a qualitative change, and at the same time, his strength was constantly getting stronger.

The appearance of this change also made Du Fei's heart arrogant and loud, he let out a long howl, and tried his best to urge Wu Zonghuan to face this double sect breaking tribulation.

"It seems that the master can even withstand this double sect breaking tribulation, it's really not interesting......" Xiao Bai stared at Du Fei for a moment, then pouted, Du Fei's appearance, obviously under the accumulation of thick hair, really has the strength to advance continuously, so this scene is not something it can worry about, at the moment its eyes also fell into the air, after a while, the corners of his mouth were suspicious, and he said to himself: "Use the Nine Heavens Falling Thunder Refining to strengthen that Spirit Dannu, I don't know what the effect is?"

The side of the Qi vein.

Li Feng and the others looked up at the thunder in the sky, and their faces were extremely weird. They were all people who had seen the Sect Breaking Tribulation more than once or twice, but it was clear that they had never seen such a powerful Sect Breaking Tribulation. Under such a continuous offensive, even though they were not in the middle of it, they also felt a burst of scalp tingling.

"This kid won't impact the Martial Sect Realm at the same time as the Sixth-Rank Intermediate Martial Sect Realm, right?" Tie Zhen hesitated for a moment before he said in a deep voice.

"This, unlikely, right?" At this time, the strange look on the corpse's face had also disappeared, and after hesitating for a moment, he was not quite sure.

"If we can really attack the six-rank mid-level martial sect realm at the same time, whether we succeed or not, we will have to kill this son!Otherwise, this son will be our henchman!" On the other hand, Li Feng gritted his teeth slightly, and said with a slight coldness.

Hearing this, after the corpse Chen and Tie Zhen glanced at each other, they both nodded slightly, at this moment, this guy called Du Fei had already brought them a lot of threats.

......

Time passed slowly, and almost in the blink of an eye, the time of the day passed. And this day, the thunder in the sky has become unimaginably dense, and in the end, even the air above the gas well is filled with thunder slurry, which also makes the surrounding Yanzong Qi become violent.

It's just that the Sect Breaking Tribulation is not endless after all, so when the sky gradually became cold the next day, the clouds in the sky finally slowly subsided, until they finally disappeared completely.

In the air well, Du Fei's body that had been standing sat down again, and at this moment, the martial arts ring on his body had disappeared, but his skin seemed to be more and more crystal clear. It's just that this kind of crystal clear is different from that of a woman, and it seems to be full of power and deterrence, and it is extremely dazzling.

"Whew-"

A moment later, Du Fei's eyes suddenly opened, and faintly, there was also thunder in his eyes, and then, he saw that the Yanzong Qi that had originally permeated his body was suddenly shocked.

"Bang Bang Bang-"

As Du Fei slowly stood up again, a violent sound came out of his body, but with each sound, an extremely powerful force erupted.

Du Fei's face did not change in the slightest, but his palm was lightly clenched, and he immediately punched out!

"Bang-"

The fist wind roared out, like a sharp blade, and slammed into the surrounding protection, instantly causing a slight ripple to spread on the protective light shield.

The power of this punch is at least several times stronger than before!

"Did it work?"

While talking to himself, Du Fei closed his eyes slightly, and his mind calmed down to the place where his dantian qi was in the sea. There, the originally crystal clear Inner Dan has turned into a golden Yuan Dan, although the Yuan Dan is only half the size of the previous Inner Dan, but the extremely strong aura is permeating from it. And in the sea of dantian qi, Du Fei's true qi has all been transformed into a faint white, and Du Fei can clearly sense that the power contained in a wisp of true qi in it is several times that of before!

"It's... Six-rank mid-rank martial arts realm!?"

After hesitating for a moment, Du Fei confirmed this, and at the same time, a smile appeared at the corner of his mouth, this time, everything was really unexpected, I couldn't imagine a gas well, but he was able to make himself rush two levels in a row, and his strength reached the sixth-grade middle-level martial arts realm!

"Master, have you succeeded?" Xiao Bai's gaze quickly fell on Du Fei's body, although it had already guessed the answer, it still couldn't help but ask.

"Well, it worked!"

Du Fei nodded with a smile, he could clearly feel that his strength at the moment was the difference between heaven and earth compared to before, and he was originally a little afraid of the powerhouses of the sixth-grade middle-level martial arts, but at this moment he could basically ignore them all!

Now he already has confidence, even if he encounters the likes of Yin Yan that day, he also has the strength to fight with him! As for Ye Qingma, who forced him away from the Da'an Dynasty that day, if he encounters it again at this moment, Du Fei is also confident that he will be completely killed!

"Congratulations to the master!" Xiao Bai and Du Fei were heart-to-hearted, and they were also extremely clear about these things, so they smiled at the moment.

"Not only that, but I also got some good things in this crossing. Du Fei smiled, and immediately turned his palm, and suddenly saw a sphere composed of thunder appear in the palm of his hand, although the sphere was small, but the breath that permeated it was thrilling!

"This is!Heavenly Tribulation Divine Thunder in the Nine Heavens Thunder!?"

Looking at the thunderball in Du Fei's palm, Xiao Bai said with a shocked face.

"Hehehe, my eyesight is very good, this thing was extracted by me when I was in the tribulation, don't look at it as only such a small group, but under my compression, there are at least hundreds of thunder powers in it, what, it's a good thing, right?" Du Fei threw the thunderball in his hand and said lightly.

Hearing this, the corners of Xiao Bai's eyes twitched slightly, and after a while, he sighed and said: "Your guts, I won't say it, you had better wrap this thing with a reincarnation spirit pattern, only the power of reincarnation can make it possible to keep it in a stable state." However, if this thing is used well, it is a rare killer weapon, and it will even be even more terrifying than after you use the mixed pill method. ”

"Really, so that means I didn't do anything wrong by taking the risk of collecting these Heavenly Tribulation Divine Thunders?" Du Fei smiled lightly, and immediately flipped his palm, and slapped the thunderball in his hand into the small world in the center of his eyebrows.

This scene, even with Xiaobai's heart, the corners of his eyes twitched slightly.

"By the way, what happened to Xiaohu and Lingdannu?" After clapping his hands, Du Fei said lightly.

Hearing this, Xiao Bai remembered that there was such a thing, and at that moment, with a wave of his palm, he suddenly saw an opening in the protective light shield, and then two figures rushed in from the outside.

"Huh?"

Seeing these two figures, Du Fei's eyes narrowed slightly, and the remaining hair on Xiaohu's body at this moment had become a little dark, and an extremely powerful force diffused out of his body, and his strength had strangely skyrocketed to the point of the peak realm of the half-step demon king, which was only one step away from the real demon king.

As for the spirit pill, its strength has not changed much at this moment, but its body seems to have become more and more powerful, and Du Fei can sense that there seems to be a touch of thunder power in its body.

"Have you used the Heavenly Tribulation Divine Thunder to refine this elixir?" After thinking for a moment, Du Fei said lightly.

"Well, this spirit pill will contain a bit of thunder power in the future, if you make a move, it is estimated that if you are not careful, even the powerhouses of the sixth-grade middle-level martial arts sect will suffer a lot of losses!" Xiao Bai said with a treacherous smile.

Hearing this, Du Fei also smiled bitterly, and immediately waved his hand, and put away the spirit pill slave, and after hesitating for a while, his eyes fell on Xiaohu's body, and after thinking for a while, he said in a low voice: "Xiaohu, if I expected it correctly, cultivating here will benefit you a lot, and this is also your chance, why don't you cultivate here and strive to impact the Demon King Realm as soon as possible, how about it?"

There was obviously a hint of reluctance on Xiaohu's face, but after a while, it still gritted its teeth and nodded slightly.

Seeing this, Du Fei nodded and said, "Xiaobai, on the premise of canceling the air seal, the formation here can still be opened, right?"

"There should be no problem. Xiaobai spread his hands.

"Okay, then after I take off the air seal, let Xiaohu cultivate here by himself, with the protection of that protective light shield, it won't be in any danger! Du Fei nodded lightly, and immediately stretched out his palm, and immediately saw the air mark on the stone pier and flew back into his hand.

After Xiaohu let out a low whimper, he had already begun to cultivate, and after seeing this scene, Du Fei's face showed a somewhat satisfied smile.

"Let's go, next, we should continue to go deep into the depths of this ancient ruins, but before that, some troubles must be solved!" Du Fei grinned, and immediately stepped on the soles of his little white feet, and his figure had already flashed out of the qi veins......
