With the addition of Shen Feitian's Heavenly Remnant Demon Trick Devouring Power, although the refining of the last nine purple heavenly tribulations of the purple bone could not achieve the best results, this time the breakthrough of the Heavenly Tribulation was not fatal to him.

I saw that in the snake body wrapped in purple fire, wisps of purple thunder and lightning raged on the purple bone's body, and finally slowly dissipated, and at the same time, the clouds above the sky seemed to have exhausted the last trace of strength, and they disappeared in just an instant.

"Whew......"

And just as Shen Fei and Xiaoxue raised their heads to look at the sky where the clouds had opened and the fog had dispersed, an angry roar suddenly came, and in that purple light, the entire snake body of the purple bone began to roll.

Through the light shield of the Purple Bone Natal Fire, both Shen Fei and Xiao Xue could dimly see that the constantly tumbling snake body, and the snake scales on it that had just been shattered by the Heavenly Tribulation, seemed to be growing back piece by piece, and the growth speed was extremely fast.

Only about half a pillar of incense has passed, and the purple bones that were dying just now have become vigorous again, and even the breath in the body has begun to skyrocket.

A purple snake shadow several feet long rose into the sky, flying in the sky, and purple fire emitted from its body from time to time, so that Shen Fei and Xiaoxue both knew clearly that maybe the purple bone at this time had reached the tenth order low-level, right?

Sou......

The purple bones that came and went in the sky, but for a certain moment, it was a snake's body, and then the two people below were stunned to see that the purple horn of the purple bone, which was originally located at the top of the snake's head, actually shrank back towards the snake's head at this moment.

"Purple Bone He...... It's not going to take on human form, is it?"

Thinking of a possibility, Shen Fei couldn't help muttering, and this guess also made Xiao Xue's eyes beside him shine, and there was a trace of extreme expectation.

You must know that the spirit demon clan, as long as they break through from the eighth order to the ninth order and go through the transformation tribulation, they will generally transform into human form, such as Xiaoxue, and the colored kite that follows Shangguan Yu.

However, the situation of the purple bone is obviously a bit special, it is obvious that it has reached the ninth order level, and it is obvious that it has already endured the transformation of the heavenly tribulation, but it is only a purple sharp horn growing on the forehead.

Now looking at the purple sharp horns retracting into his mind, Shen Fei Xiaoxue thought of that possibility, if this is not transformed after breaking through to the tenth-order spirit demons, it will be really too unbelievable.

But Shen Fei and Xiaoxue's wishes were destined to be frustrated, the purple bones in the sky, after the purple sharp horns retracted into their minds, the snake mouth let out a more majestic roar, and at the same time, there was a strange change on his snake head.

Originally, it was just a raised purple sharp horn, but this time there was a bulge at both ends of his snake's head, and the strange horns that emerged from both sides of his head made Shen Fei and Xiaoxue look at each other.

"What's that?"

Xiao Xue made a meaningless voice in her mouth, she knew that Shen Fei couldn't answer this question, just to vent the doubts in her heart.

When Xiaoxue's voice fell, the things at both ends of the purple bone snake's head had grown wildly, and at this moment, Shen Fei suddenly found that the thing that grew out of the purple bone seemed to be a little faintly familiar.

"It's Dragon's Horn!"

Originally, Xiaoxue didn't think about what she wanted Shen Fei to answer, but at this moment, she was exclaimed by the latter, because when she was in Nanyan Lake, the Southern Fire Academy of the Human Spiritual Realm, when the Dragon Turtle Kan Xun, the overlord of the Realm, had just come out, he was such a dragon horn.

Although the Dragon Turtle Kanxun is fundamentally different from the Heavenly Dragon Clan, the Lord of the Spirit Demon Realm, that head is extremely similar, and Shen Fei has already popularized the differences and commonalities between the two at the beginning, so there is no doubt at this time.

Shen Fei had always suspected that the Purple Bone, a fiery spirit snake, was related to the Heavenly Dragon Clan, the most mysterious and powerful race in the Spirit Demon Realm, especially after the Purple Bone had refined back to his natal fire and then refined two snakes.

Because the ordinary Fire Spirit Snake may not be able to reach the level of the Purple Bone at all, and some magical things are not something that ordinary Fire Spirit Snake Spirit Demons can express.

Reaching the ninth level without transforming into a shape, and now breaking through to the tenth order, he has not turned into a human form, and even has two dragon horns growing at the head of the snake, which seems to confirm some of Shen Fei's speculations all along.

"Could it be that in the previous life of this guy Zigu, he was really a certain powerhouse of the Tianlong clan?"

Hearing Shen Fei's exclamation, Xiaoxue was also thoughtful, as a spirit demon, some of the inheritances in her mind must have some understanding of the mysterious dragon clan, and as soon as Shen Fei reminded her, she thought of a lot at the moment.

It's just that above the sky, the change of the purple bone is not finished, and when the dragon horns at both ends of its forehead grow to a certain extent, four protrusions suddenly appear at the front end of its snake body and not far from the snake's tail.

"Is it ......?"

Shen Fei, who had been staring at the purple bones, thought of that possibility in his heart, and couldn't help but look happy, he really wanted to see if the guess in his heart was true?

The fact did not surprise Shen Fei's expectations, only to see that a moment later, after the purple bone roared up to the sky, from the four places of his snake body, four hideous palm claws suddenly appeared.

"Sure enough, it's a dragon's claw!"

Seeing this, Shen Fei no longer doubted, the biggest difference between the heavenly dragon and the snake spirit demon is that the dragon is born with claws, while the snake spirit demon does not, at this time, after the purple bone breaks through the heavenly tribulation, not only the dragon horns are born on the head, but also the dragon claws grow on the body, and the appearance of the legendary heavenly dragon clan is getting closer and closer.

The purple bone that gave birth to two dragon horns and four dragon claws, the appearance at this time was very different from before, it seemed that it was really a purple dragon flying around in the sky, which looked extremely pretentious.

And looking at the flying purple bones, Xiao Xue seemed to think of something, and suddenly turned her head and asked, "Shen Fei, aren't the Tianlong clans all water attributes?

Shen Fei had to get some simple information about the Tianlong clan popularized by the ghost elders, and when he heard Xiaoxue say this, he was immediately stunned, the secret path is not compatible, and the attributes of purple bones are really a big problem.

But how did this person and a tiger know that the purple bone not only belonged to the Tianlong clan, but also belonged to the only fire attribute Tianlong of the Tianlong clan, and it was precisely because of his fire attribute that the dragon clan elders cut the dragon body into four pieces on the broken dragon platform.

Of course, these memories of the past life are not only unknown to Shen Fei and Xiaoxue, but also to Zi Gu himself, and it is impossible to know until he finds the metamorphosis of the snake head and refines it.

After another half an hour, the breakthrough of the purple bone this time was finally completed, and the purple snake body that was several feet long was already rapidly shrinking under a change, and finally turned into a mini purple snake that was only a few feet long.

"Hehe, purple bone, second sister, I still like your cute appearance!"

Watching the purple bone fall from the sky, Xiaoxue, who was relieved, was joking again, and it didn't have the anxious appearance when he watched the purple bone die just now.

Zi Gu naturally knew Xiao Xue's character, and a smile flashed in the snake's eyes, but he turned the snake's head and said to Shen Fei: "Big brother, this time, thank you very much!"

Although the purple bones were deranged by the powerful Nine Purple Thunder Heavenly Tribulations just now, he still remembered the loud shout in the haze very clearly, and he knew that if it weren't for that loud shout, he was afraid that he would have been scattered by now.

Especially the trace of devouring power contained in that natal fire, now that Zi Gu thinks about it, it is definitely not his own power, and he has fought side by side with Shen Fei countless times, he can naturally guess something.

Therefore, Purple Bone's words were heartfelt gratitude, because it was the heavenly grace that pulled him back from the hands of death, and it was the guarantee that he could reach the current tenth-order low-level spirit demon.

"Zi Gu, since you call me big brother, don't say such things again in the future!" Hearing this, Shen Fei's face sank, and the words he said were also extremely serious.

Shen Fei was serious here, but Xiao Xue had already taken over and said: "That's right, Zigu, what are you polite to this guy, anyway, he has a lot of enemies, you can help him kill a few more enemies in the future!"

Hearing Xiaoxue's words, the purple bone snake head nodded, in fact, if he hadn't appeared just now, maybe Shen Fei would have died in the hands of Zhaoguang, the deacon of the Soul Doctor Holy Mountain, and it was really unclear who was helping whom in this matter.

But anyway, now that the three brothers and sisters are together, everything is happy, Shen Fei sighed slightly, and said, "Purple Bone, your breakthrough should have been completed, right?

In Shen Fei's opinion, the purple bone snake's body has changed greatly, and the breakthrough must have been completed, but unexpectedly, his voice fell, but the purple bone shook the snake's head and said: "It takes a process for the spirit demon clan to break through from the ninth-order high-level to the tenth-order low-level, and my current demon pill qi has not been completely transformed, and it may take a little time." ”

"How long will it take?" Shen Fei frowned, to be honest, after discovering that the Soul Doctor Holy Mountain Xiaoshan Subjective Yu had already targeted him, he urgently needed help, and Purple Bone, the spirit demon helper who had broken through to the tenth order, was undoubtedly very powerful.

"About a month!" Purple Bone gave such an answer, and Shen Fei didn't say anything more, he knew that now that Purple Bone had just broken through, if he didn't hurry up and transform the Demon Pill Qi, maybe it would be a big trouble for his future improvement.

"However, this transformation demon pill qi is different from the previous refining of the snake tail, and it doesn't need a human protector!" Purple Bone said this, and the snake eyes had already turned to Xiao Xue's body, and the meaning was extremely obvious.

Shen Fei didn't doubt this, if he only transformed the demon pill qi now, the purple bone could be stopped at any time, and with the tenth-level demon pill qi of the purple bone, I'm afraid that no human or spirit demon would dare to come to him for trouble, right?
