"Nine turns of Nirvana, nine turns of internal breath!"

Calming down, Nie Yun sank the thick true qi into the sea of qi in an instant, and the seven great dantians led the madness to operate according to a special trajectory!

The Nine Turns Nirvana Gong is very weird, and it can also increase cultivation during normal operation, but once this cultivation accumulates to the point where it can be transformed, there will be no further progress, and then it must impact Nirvana!

Although Nirvana is very dangerous, if it is successful, it is like being reborn from the fire, whether it is the body or liliang, there will be a qualitative leap, which makes people greatly improve their strength!

Just like the current Nie Yun, if he cultivates step by step, he can break through from the peak of the True Qi Realm to the early stage of the Out of Body Realm at most, but Nirvana is different, once he succeeds, he can at least reach the peak of the Out of Body Realm, or even the early stage of the Chenggang Realm!

Jumping one level at a time and doubling his strength is the main reason why the Nine Turns Nirvana Skill is dangerous to cultivate, but it still makes Nie Yun choose it without hesitation!

"Breath flow, Nirvana!"

With a low shout, Nie Yun's whole person was like an old monk, and he instantly entered a state of nirvana

．

"Yun'er doesn't eat or drink, nothing will happen!" Nie Ling looked at the cave where Nie Yun was retreating, looking anxious.

Since her son went into retreat, she, the biological mother, has been picking fruit every day, and even catching some wild beasts and roasting them outside, but she didn't recognize them on the first day, and the food was brought back untouched!

It's okay if she doesn't eat for a single day, Nie Ling won't be too anxious, but she still hasn't eaten the next day, and no one has come out of the cave on the third day!

All the way to the fourth day, the fifth day......

It's the 10th day today!

If it weren't for the tiger-headed beast desperately guarding the entrance of the cave, and his son had also explained before, I'm afraid he would have been unable to resist rushing in!

No matter how strong the strength of the Qi Sea Nine Heavens is, even if it reaches the Nine Folds Supreme, it will not be able to break the valley, and if you don't eat or drink for ten days, what is going on?

"This tiger beast is Yun'er's contract demon beast, if there is a problem, it will definitely be the first to rush in, don't worry!"

Nie Xiaotian stood beside his mother Nie Ling, although he was not worried about it, and kept rubbing his hands, he betrayed him.

However, at this time, he no longer had the same sluggish appearance as before, his eyes were bright, and his demeanor was full of liliang, and at a glance, he knew that it was the manifestation of the first layer of the Lingxi Refining Body Technique!

"Also, Xiaotian, have you noticed that Yun'er has been completely different from before since she woke up that time, she is a lot more confident, and she seems to have more secrets on her body!" Thinking of her son's various miracles, the anxiety in Nie Ling's heart was reduced a lot, and she sighed.

"This may have something to do with his master, many strong people like to hide their names, even if they accept apprentices, they don't want apprentices to say who he is, Yun'er doesn't want to say, let's better not ask, save him embarrassment!" Hearing his wife say this, Nie Xiaotian nodded, and suddenly smiled, "He has a good master, his strength is improving quickly, and his self-confidence is normal, but I never thought that he actually had a beast taming dantian and could subdue demon pets!"

"Yes, Yun'er has surprised us too much, it seems that you, the first day of Luoshui City, are probably going to change your name!"

"It's also my son who changed his name, haha, as long as he is stronger than me, what is this false name?Besides, I'm not a first-day genius anymore!" After Nie Xiaotian Heavenly Spirit Refining Body Technique was completed at the first level, his entire mental state was completely different from before, and he seemed to have returned to the high-spirited age of the year.

"Hehe!" Seeing her husband's mental state change, Nie Ling was also very happy, nodded, and was about to continue talking, when she suddenly heard a roar in her ears.

Thundered!

There was a tremor under his feet, and a special aura immediately erupted from Nie Yun's retreat, and the powerful aura made the faces of the two of them change at the same time.

"What is this?"

Feeling this breath, Nie Xiaotian and the others felt as if they were standing in the midst of the stormy waves, and they couldn't resist at all!

"Could it be that Yun'er has been promoted? Even if it is promoted...... It's impossible to have that kind of strength, what's going on?"

When Nie Yun was in retreat, he only had the strength of the peak of the fourth true qi realm of the Qi Sea, even if he was progressing, the fifth layer was in the middle stage of the body realm, but the breath in front of him, liliang was tumbling like a mountain, and the breath was as rich as a tide, it was definitely not something that could be found in the middle stage of the body realm!

Not only is there no middle stage of the out-of-body realm, but even the middle stage of the Chenggang realm will never be!

"Brother?"

The movement was so loud that Nie Xiaofeng, who had been cultivating, also came to his senses at this time, walked out of his place of residence, and looked at the cave where Nie Yun was retreating, with an inexplicable shock in his beautiful eyes.

"Brother Nie Yun......"

Nie Tong also walked over, and at this time, his petrified legs were actually able to bend slightly when he walked, and it seemed that there were already signs of de-petrification!

Nie Yun also taught him the Spirit Rhino Refining Body Technique before the last retreat, and although he did not cultivate the first layer to Dacheng like Nie Xiaotian at this time, he also relieved his petrified legs and made his actions more convenient.

As the supreme technique of the Demon Race, it is definitely no problem to alleviate petrification, but the time for Nie Tong to petrify is too long, and if you want to completely eliminate it, it is impossible to complete it without a few months of hard cultivation!

"Uncle Xiaotian, this breath is from my younger brother......"

Nie Xiaofeng looked at Nie Xiaotian with a puzzled face.

"I don't know, but it looks like Yun'er should be out of the customs......" Nie Xiaotian didn't confirm whether this breath was emitted by his son, but thinking of his son's various miracles, he still nodded.

"Brother is going to get out of the customs, but this breath ......" Nie Xiaofeng covered his lips with his palms, his eyes were round, he couldn't believe it, ten days ago, he only had a true qi realm peak brother, and five days later he would have such a strong coercion!

Rumble!

Before she finished her words, the tidal wave of aura suddenly retracted and disappeared in an instant, and then the stone cave where Nie Yun was retreating "boomed", and countless gravel surged out of it, blasting the dust all over the ground in all directions, and the entire valley was filled with dust, making it impossible to see what was going on inside the cave.

"Yun'er ......"

Not seeing what was going on in the cave, Nie Xiaotian and Nie Ling glanced at each other, and each saw a trace of anxiety in each other's eyes.

With such a powerful explosion, could it be that his son's cultivation went mad and there was a problem?

Can...... I've never heard of such a powerful explosion going mad!

Wow, wow, wow!

Just when the four of them were full of anxiety, suddenly there was a sound of gentle footsteps landing on the ground in front of them, and then a figure emerged from the gray dust.

"Dad, mother!"

The figure saw Nie Xiaotian and Nie Ling, who were full of anxiety in front of him, and smiled faintly, revealing his white teeth.
