Huh... Huh...

The top floor of the Nanhuo Refining Building is full of energy. If outsiders are present, their eyes will fall off, right?

Zigu possesses the blood of the dragon. The sound of the fourth-level spirit demon breaking through to the fifth-level spirit demon is much greater than that of ordinary spirit demons. Chen Fei practices the heavenly-defying technique of Tiancan Demon Art. One person and one snake add a breakthrough, and it is considered good not to overturn the Nanhuo Refining Building.

Especially Chen Fei, who had obtained another breakthrough opportunity within seven days, had already figured out the reason. It was probably all the credit of the purple bone's natal fire?

Chen Fei had practiced on the 59th floor of the Nanhuo Refining Building for a full half month, and had a battle with the elixir demon at the peak of the Nine-level Person Pill Realm before, so it was natural to achieve a breakthrough.

However, at the top of the Nanhuo Refining Building, which does not have rich fire attribute energy, Chen Fei had to swallow some of the energy of its natal fire due to the purple bones. This energy is probably the main reason for him to make a breakthrough at this time.

It can be said that the entire Nanhuo Lian Burning Tower fire attribute energy was formed by the purple bone, the natal fire that had existed for thousands of years. The fire attribute energy that overflowed from it can be used for low-level cultivators or even the nine-level human alchemy powerhouses like Chen Huai Jiang Ran to practice.

But now, Chen Fei directly swallowed a large amount of energy from his natal fire, which could only break through the first level, or because he was not practicing fire-attributed skills. If he gave these energy to another young genius who practiced fire-attributed skills to absorb, he would probably get greater benefits, right?

Of course, except for Chen Fei's Tiancan Demonic Art's devouring power, who dares to forcefully absorb such a rich fire-attribute energy like this? Maybe in the end, the energy will not be swallowed up, but will make him burn and die.

But no matter what, at this time, every man and a snake have reached the critical point of breaking through to the next level. In contrast, Zigu's breakthrough will definitely improve its strength more than Chen Fei, after all, it is a breakthrough of a large level.

The breakthrough of one man and one snake lasted for three hours. When the top floor of the Nanhuo Liquid Building slowly calmed down, Chen Fei's breakthrough was first completed.

The red light of Tiancanyu's right arm in the dantian had already converged. Chen Fei, who opened his eyes, felt a much stronger power and elixir energy than before, and a satisfactory curve could not help but blew up the corner of his mouth.

"Eight-fold Soul Realm!"

Chen Fei stood up, chuckled, and then turned his gaze to the purple bone snake floating in the air not far ahead. The slightly blooming purple light showed the purple bone's breakthrough, and finally came to an end.

"grumble!"

A high-pitched sound of snake came from the mouth of the purple bone's snake bone. The next moment, when the purple light shone on its body again, Chen Fei, who was not far away, suddenly felt as if a wild beast suddenly woke up.

At this moment, Chen Fei even saw a touch of violence belonging to the spirit demon from the empty eyes of Zigu, and the most common one was a trace of noble dignity.

Since Chen Fei met Zi Gu in Huoyun Cave, this little guy has always shown an extremely gentle and gentle manner. Of course, that is only for Chen Fei alone, it is impossible for him to have such a feeling for the enemy who dares to hurt Chen Fei.

However, at this time, Chen Fei was stared at the empty bone eye of Zi Gu, and his vest was a little cold. In addition to the reason why Zi Gu successfully broke through to the fifth-level low-level spirit demon, there was also an indescribable feeling, as if Zi Gu was no longer the purple bone who obeyed his words.

Chen Fei had a feeling that this time he broke through to the purple bones of the fifth-level low-level spirit demon, he was afraid that his spiritual intelligence would no longer be in the hazy state he had before. It should be noted that ordinary fifth-level low-level spirit demons were similar to those of human adults.

Chen Fei was also a little worried. Is the purple bone, who has the bloodline of the Tianlong clan, still willing to follow him after his spiritual intelligence increased? That is really uncertain. That faint nobility may be the hidden attribute of the bloodline of the Tianlong clan?

The Spirit Demon clan was originally arrogant. Unless a human really conquered it in strength, it could be willing to follow this human. On the continent, except for some powerful soul doctors who can use their souls to seal the Spirit Demon to make it obedient, there are almost no other contractual means.

Chen Fei had the opportunity to use the soul method to control Zigu, but he liked this little guy very much, and in the end he did not use this method, because he had already regarded Xiaoxue Zigu and other spirit monsters as their relatives, pure relatives.

However, just now, when the purple bone initially refined the fire of his birth and broke through to the fifth-level low-level spirit demon, the strangeness in his eyes made Chen Fei feel pain, because he knew that this powerful spirit demon with a trace of the blood of the dragon flowing in his body would probably leave him the next moment.

With the blood of the dragon, how could it be willing to be with a human practitioner who is worse than it? If Zigu’s choice is based on common sense, it is indeed not too difficult.

And if you think in another direction maliciously, Chen Fei forced himself to keep the purple bones by his side as a thug when his spiritual intelligence was not opened. At this time, the purple bones broke through to the fifth-level low-level spiritual demon, and his spiritual intelligence returned to normal. I am afraid that it is not impossible to settle the accounts after the autumn.

However, just as Shen Fei was thinking about it, the purple bone suspended in the air was condensed by purple light, and then there was a trace of violence belonging to the spirit demon. The next moment, he saw it swaying its tail in the air and suddenly appeared in front of Chen Fei.

Chen Fei was shocked by this speed, but then he felt a familiar feeling coming from Zigu, without any signs. He inexplicably confirmed that Zigu was still the original Zigu, and his admiration for him had absolutely no change at all.

"Ji! Jiji!"

Although the purple bone's hollow bone eyes still had no emotion, the sound of these two snakes made Chen Fei finally relieved, and the posture of wandering around him was as always.

"Hehe, Zi Gu, congratulations!" Chen Fei relaxed and immediately spoke congratulations. After hearing Chen Fei's words, Zi Gu shouted happily twice again, then directly waved his body and suddenly landed, and finally circled Shen Fei's right arm twice.

His right arm suddenly cooled down. When Chen Fei lowered his head, he realized that he was actually invisible. Fortunately, only purple bones existed here, otherwise the man would have lost it. He quickly took out his clothes from the calm bag and put them on.

It’s just that clothes can be used to cover up, but the naked head and eyebrows are not so easy to solve. However, Chen Fei is not a person who cares about the details. These things are insignificant compared to the breakthrough in strength.

When this man and the snake were immersed in the joy of breaking through, the floor below the Nanhuo Lian Burning Building had already had a great ups and downs.

"What's going on? Why is the energy of fire attribute weakening?"

"Why can't I sense the fire attribute energy?"

"What happened? Did the Dan Demon start attacking the Nanhuo Academy?"

“…”

At this time, the geniuses in the Heavenly Courtyard on all floors of the Nanhuo Refining Building immediately sensed the weakening of the fire-attribute energy, and even some geniuses on the lower level could not sense the rich fire-attribute energy before.

However, some other keen people guessed from the perspective of the appearance of the alchemy demon before, and had never thought about all of this, because the purple bone reclaimed its own natal fire.

The Nanhuo Refining Building has existed here for thousands of years, and all of this is because the powerful natal fire of Zi Bone is releasing the natal flame of fire attribute energy all the time, providing the Nanhuo Refining Building with a continuous stream of fire attribute energy.

But now, the fire of the natal body has been re-refined by the purple bone. Although it is only a preliminary refining, it is no longer possible to be used as a nutrient for the energy of the Nanhuo Refining Burning Tower Fire.

Chen Fei had actually thought of this before, but because of the purple bone, he could not have any other thoughts.

The purple bone that began to refine the purple flame had no way to stop, and Chen Fei had no reason to stop the fire, which originally belonged to the purple bone.

Chen Fei knew the final result that would inevitably be embarrassing, but he would not regret it. Zigu did nothing wrong, but for Nanhuo Academy, the Nanhuo Refining Building will probably be just a sky-sky building for nostalgia.

Chen Fei had no intention of caring about these geniuses in the heavenly courtyard on the lower floor at this time, but when he just put on his clothes and was about to say something to Zigu, his heart was thrilled at this moment.

"What's going on?"

Chen Fei stroked his right hand to his heart, and his face had changed drastically at this moment. This palpitation was unreasonable, but it was this intuition without warning that made him vaguely guess some clues.

Because of this kind of palpitation, this is not the first time Chen Fei felt it. When he was in the Lieyun Palace in the mortal realm, as long as Shangguan Yu encountered the danger of life and death, he would have such sudden palpitations.

This kind of palpitations happened twice, and those two times later proved that Chen Fei's intuition was indeed because Shangguan Yu was in great danger.

So at this time, while Shen Fei's face changed drastically, he subconsciously thought of the things he had when he was in Lieyun Palace. Shangguan Yu was in danger, and this had already taken shape in his mind.

Chen Fei can't tell what kind of attitude he is now about Shangguan Yu, but no matter what his attitude he is, he cannot let him be in extreme danger. There is no doubt about this.

"Zigu, let's go!"

Chen Fei's palpitations became increasingly intense, and he also knew that things might have been at an extremely terrible critical moment. Perhaps something unpredictable would happen to Shangguan Yu in time.

The figures of a man and a snake quickly disappeared on the top floor of the Nanhuo Refining Building. When some geniuses on the lower floor of the Heavenly Courtyard saw the one-armed figure, they couldn't help but show a bit of horror and awe.
Chapter completed!
