"Xuan tortoise shell?" Nie Fan was slightly stunned.

"Yes, Xuan Tortoise Shell, this Xuan Tortoise is a divine beast-level existence, although it is much worse than the Xuanwu Divine Beast, but it is also a primary divine beast, this martial art actually uses a Xuanwu Armor as a inheritance, and the level is not low. Killing Heaven explained.

Nie Fan was overjoyed when he heard it.

Looking at the Xuan Tortoise Shell in Nie Fan's hand, Nifu felt that he seemed to be a little sorry for Nie Fan, if he had done it before, he would never have felt like this, but now that Nie Fan has become a friend of his mire clan, he definitely can't see through this thing, maybe it's not very good, so he felt a trace of guilt in his heart.

"Xiao Fan, there are still three earth spirits here, which are left behind after the death of our mire tribesmen, although the origin of your future perception is not necessarily the origin of the earth, but it should be useful to you. After saying that, Mud Fu took out a round ball of earth.

Nie Fan was stunned.

"No!"

Nie Fan suddenly looked at the mud seriously, he knew that this earth spirit was cultivated by the mire tribe with great difficulty, and it could also be said to be the demon pill of the human race's dantian beast clan.

"Don't worry, one of these three earth spirits was born and died at the moment when the peak of the Yuan Emperor broke through the Yuan Sheng, but in the end, all the essence of the whole province was condensed into it, and the other two were born and died when the Yuan King broke through the Yuan Emperor at the peak of the ninefold peak, although these three earth spirits can be integrated into the earth spirit of our mire clan itself, but it will cause a certain obstacle to the people of my mire tribe. ”

"What do you mean?" Nie Fan didn't understand.

"Our mire clan has existed for a long time, and it has been shiyan many times, but after fusing the earth spirit of the predecessors, the cultivation is at most comparable to the cultivation of the predecessors, and even weaker than the cultivation of the predecessors, and it is impossible to break through, which is why our mire clan people do not fuse the earth spirits of the predecessors, these three earth spirits are also Lang Fei here, if you step into the peak of the Yuan Emperor in the future, you can also perceive the origin of the earth in the earth spirit, and it may be possible to help you break through that barrier, and it is not impossible. ”

"Or if you directly condense it as a demon pill, it is not difficult for the energy in it to help you hit a higher level. Mud said seriously.

"It's hard to be gracious. Nie Fan didn't want to take it, but looking at Nifu's serious appearance, Nie Fan knew that he thought it would make Nifu sad.

"Okay, I'll take it, and I'll do it if the mire need me someday. Nie Fan said solemnly.

"I believe it. Mud smiled.

"Okay, I won't bother you, I don't think it's so easy to rush away, I'll take you to a quiet place where you can meditate and maybe you can get the martial arts in it. ”

Nie Fan nodded slightly. Soon, Nie Fan came to a small space.

"This is the space created by our mire ancestors, this is also the only space enchantment of our mire clan, you explore here, if you want to leave, let me know and I will take you away, after all, this place is not suitable for you. Mud Fu looked at Nie Fan and smiled.

Nie Fan did not refuse, but nodded with a smile.

Immediately the mud ambushed and left, Nie Fan sat down, and the Xuanwu armor in his hand was also placed on his legs by Nie Fan, and then Nie Fan was not verbose, and directly released the power of the soul, which directly covered the Xuanwu tortoise shell in an instant.

Nie Fan was slightly stunned, his soul power could perceive any special place in this Xuan Tortoise Shell, but what made Nie Fan puzzle was that everything he perceived was not the slightest difference from what he saw.

"What's going on?" Nie Fan was puzzled.

Ji Tian was also puzzled at this time, although he was an old antique, he didn't know everything, and at this time, looking at the Xuan tortoise shell on Nie Fan's thigh, he also shook his head helplessly.

"Do you need to use anything to open this Xuan Tortoise Shell?" Nie Fan whispered, he had also told himself before, and his soul power rushed in just to get the name of this martial art, but there was no other news.

What's the use of the name, the Fa decision without cultivation is simply like the feeling of seeing a naked woman who makes people squirt nosebleeds but can't do anything.

Knock Nie Fan's middle finger bent on this Xuan Tortoise Shell, constantly tapping to find the mechanism to open this Xuan Tortoise Shell, but Nie Fan's soul power rushed in before, but nothing was found.

"Burn with your flame. Killing Heaven suggested.

Nie Fan frowned.

"If it burns out, you can stay with me. ”

"Cut, then you can do it yourself. ”

Nie Fan looked at Killing Heaven speechlessly, and then summoned some Xiao Ling, and suddenly Xiao Ling overflowed according to Nie Fan's intentions, and a faint flame rushed out, Nie Fan's palm directly covered the Xuan Tortoise Shell.

Three minutes later, the tortoise shell didn't react in the slightest.

"Intensify your efforts. Nie Fan whispered.

Suddenly, the temperature of the flame suddenly became stronger.

But after a minute, the tortoise shell still didn't change in the slightest.

"Come again!"

Nie Fan frowned, this Xuan Tortoise Shell was so strong, Xiao Ling's flames couldn't melt it, it seemed that this Xuan Tortoise Beast could not be classified among the divine beasts.

Half an hour later, Nie Fan's brows furrowed, and Xiao Ling also pouted helplessly, his flames could not cause the slightest damage to the Xuan Tortoise Shell.

Looking at Xiao Ling, who was a little tired, Nie Fan smiled apologetically.

But looking at the Xuan Tortoise Shell in front of him, Nie Fan was completely disappointed.

"The Xuanwu Turtle Beast and the Xuanwu are close relatives, and it is said that the Xuanwu Turtle Beast has a trace of the essence blood of the Xuanwu Divine Beast flowing from its body. "Killing the sky muttered.

Nie Fan looked at Killing Heaven suspiciously.

"Don't you have a basalt seed source thunder on you, you can use your basalt seed source thunder to try it out, maybe you can inspire something. Killing Heaven suggested.

After listening to Killing Heaven's words, Nie Fan also nodded slightly, there was no other way at this time, and this was the only way.

A Xuanwu mark suddenly appeared behind Nie Fan, and it was also at this moment that the Xuanwu Seed Source Thunder in Nie Fan's meridians, which could not be seen by absorption, also overflowed with blood, and followed Nie Fan's meridian pulse to Nie Fan's palm.

This is the first time that Nie Fan has really used the Xuanwu Seed Source Thunder, Nie Fan has condensed a lot of Xuanwu Seed Source Thunder in the ancestral land of Xuanwu City, although it is to help the little girl condense, but Nie Fan has also benefited a lot.

At this moment, a cyan thunderbolt overflowed from Nie Fan's palm, and there were Xuanwu marks on it.

It was also at this moment that Nie Fan's eyes showed surprise.

Before the Xuanwu Seed Source Thunder in his palm could control it, it directly sank into the Xuan Tortoise Shell on his thigh, and it was constantly circulating on this Xuan Tortoise Shell.

The Xuanwu sigil was constantly flashing with a different color from this thunderbolt, which was obviously a light black luster beating.

"Push it up!"

Killing Heaven urged.

Nie Fan nodded slightly. Suddenly, the thicker Xuanwu Seed Source Thunder rushed out of Nie Fan's palm, and then completely wrapped the Xuan Tortoise Shell, and in just ten seconds, the Xuan Tortoise Shell suddenly trembled.

There was a cracking sound from this Xuanwu Seed Source Thunder, and the crisp sound made Nie Fan's eyes light up, obviously this Xuanwu Seed Source Thunder seemed to have touched this Xuanwu Tortoise Shell.

There was another crisp click, and fine cracks suddenly appeared on the turtle shell, and purple light flowed out one after another.

"Purple level martial arts!"

"And it's a purple-level mid-level martial art!" Killing Heaven suddenly shouted.

With a crisp bang, the entire Xuan Tortoise Shell suddenly burst open, and it was also at this moment that a violent soul mark rushed directly into Nie Fan's soul sea along the soul power released by Nie Fan.

In an instant, Nie Fan's head hurt, and a feeling that made Nie Fan feel painful spread, and in just an instant, Nie Fan's clothes were soaked with cold sweat.

After a while, Nie Fan's furious soul sea finally calmed down slowly.

At the same time, the soul imprint that rushed into Nie Fan's sea of souls was also directly swallowed by Nie Fan's sea of souls, and everything in it also appeared in Nie Fan's mind.

I saw that one after another terrifying big seals appeared in Nie Fan's mind, and there was a Xuanwu mark on each big seal, which seemed so indestructible and gave people a kind of heavy depression!

"Xuanwu Seal!"

Three big characters appeared in Nie Fan's mind, looking at the terrifying big seal, Nie Fan was stunned for a moment, he was on the Hidden Dragon Continent, Xuan Xiaoyu once obtained a Xuanwu Seed Source Thunder for her, which seemed to contain a martial art, which was called the Xuanwu Seal!
