Moaning slightly, he glanced at Zhang Chu and the others who were still some distance away from the top of the mountain, and Zhang Chen slowly walked towards the palace.

When they come up, it is estimated that there will be some time, so take advantage of this time to investigate the specific situation of the palace first.

The feeling fell on the gate of the palace, and Zhang Chen only felt a blazing sensation coming.

I used a little force, but I was surprised to find that the gate didn't move at all!

Although he didn't use all his strength, the physical body of the peak of the Great Saint Realm plus the cultivation of the peak of the Manifestation Saint Realm,

With that power just now, even if an ordinary Great Saint Realm peak powerhouse received it, he would suffer a heavy blow!

With such strength, you can't open a door!

Taking a deep breath, Zhang Chen's spiritual power surged, gradually increasing his strength.

Sancheng...... Forty percent ...... Fifty out of ......

Sixty percent!

"Boom!"

"Zizizi!"

Zhang Chen used a full sixty percent of his strength before the palace gate roared and gradually opened.

As soon as a gap was opened, before Zhang Chen's face could smile, his face changed suddenly and retreated towards the rear.

In the next moment, a black flame flew out of the crack where the palace gate had been opened.

The black flames scorched the space, and as soon as they appeared, all the surrounding spaces dispersed.

Zhang Chen only felt that the entire peak of the Refining Instrument Peak had become extremely hot at this moment.

His gaze fell on the black flames, and Zhang Chen's face showed a look of surprise and abruptness.

It's so dangerous, it's just a little, it's almost that he's contaminated with black flames.

There is a great terror in this black flame!

Zhang Chen felt that even if he came into contact with the black flame, it would be more than lucky!

Fortunately, it was he who opened the palace gate, if it was Zhang Chu and Hua Wudao who came to open it,

The black flame just now is estimated to have killed them on the spot.

This made Zhang Chen a little lucky, thanks to him to investigate it in advance, otherwise it would have made a big mistake.

Black flames fluttered in the void, as if they had spotted Zhang Chen, and gradually moved closer.

Everywhere you go, nothing exists.

Zhang Chen couldn't help but retreat to the side of the stairs, glanced at the stairs below, and Zhang Chen gritted his teeth.

"Fight!"

If it goes on like this, I always feel a little unwilling.

The dignified monk was actually forced back by a flame that could only dimly scinch!

Zhang Chen's purple pupils suddenly flashed with a strong light, and his gaze moved, falling on the black flame.

Hongmeng Dao is supernatural, Hongmeng Dao is fire!

In the next moment, a purple flame appeared out of thin air next to the black flame, and immediately after that, it directly touched the black flame.

"Buzz!"

"Boom!"

The sound of flames burning sounded, and the purple Hongmeng Dao fire and the black unknown flame were entangled, scorching each other.

When Zhang Chen saw this scene, he showed surprise.

Hongmeng Daohuo actually confronted this black unknown flame!

For the first time in his life, Zhang Chen saw Hongmeng Daohuo meet his opponent.

Before this, whether it was the lion maniac of more than 200 people on the Tianjiao list, or the lonely night of the 30th Tianjiao list,

In the face of Hongmeng Dao Fire, they are helpless, either the strong man breaks his wrist, or he is directly burned by Hongmeng Dao Fire!

In this incineration process, there is no resistance to the kind!

Even if this black flame is stronger than Lion Maniac and Dugu Night, in Zhang Chen's opinion, it can at least be suppressed.

But unfortunately, it did not achieve the effect that Zhang Chen expected.

Although Hongmeng Daohuo did not fully stimulate his power because of his cultivation.

But Zhang Chen is confident that the current Hongmeng Dao Fire, even if it is touched by the quasi-emperor powerhouse, the only way to get rid of it is to cut off the burned part!

There is no other way!

And now, this black flame actually resisted the attack of Hongmeng Daohuo, and was still entangled with it, for a while, there was quite a tendency to be on par.

In Zhang Chen's purple pupils, the purple light bloomed again, faintly, as if there was a great terror brewing in it.

Looking at the black flames, Zhang Chen hesitated.

Hongmeng Dao Fire can only be released twice a day now, and if it is more, his eyes will not be able to stand it and suffer a traumatic blow.

At that time, it was estimated that it would not be able to be used for a while.

Zhang Chen wanted to keep it once as a hole card, but now in this situation, it seems that he can't keep this hole card.

At this moment, Hongmeng Dao Fire seemed to be annoyed, and the momentum of the flames suddenly soared, directly enveloping the black flames.

The black flame that could still compete with the Hongmeng Dao Fire, at this moment, there was a sense of powerlessness.

Seeing this, Zhang Chen showed a smile.

It seems that there is no need for him to use the second Hongmeng Dao Fire.

After hesitating for a moment, Zhang Chen came to the front of Hongmeng Daohuo.

The Hongmeng Dao Fire, which could have easily scorched the space, did not give Zhang Chen the slightest sense of heat, and even some coolness.

In this regard, Zhang Chen was not surprised.

The flames he released naturally did not cause him harm.

After all, he was curious, what was this black flame?

"The key item detected by the host has been discovered, the Holy Relic Emperor Fire, which can be recovered!"

"Excuse me, host, do you want to recycle?"

The voice of the system suddenly sounded in Zhang Chen's mind.

Holy Relic Emperor Fire?

System recycling?

What is all this?

Zhang Chen was a little confused.

Does the system also have a recycling function?

Suddenly, Zhang Chen's expression froze.

"System, you said that this black flame is the Emperor Fire of the Holy Relic Clan?!"

The Holy Relic Clan, this word and race, Zhang Chen is no stranger.

Under the Emperor City, where their Ancient Zhang family was located, there was a Holy Relic Clan.

From the ancient times, it has been sealed until now.

"Yes, the host, it is the Holy Relic Emperor Fire, this black flame is left by a strong person of the Holy Relic Clan at the peak of the Great Emperor."

"Because of the long years, the power has passed, and now the power is gone."

This black flame left behind by the Holy Relic at the peak of the Great Emperor?

Zhang Chen was a little shocked.

The origin of this black flame is so big?

No wonder it can resist the scorching of the Hongmeng Dao Fire, and its power has been greatly reduced, otherwise he will definitely die!

Zhang Chen is confident in his own strength, but he is not conceited.

Not to mention the peak of the Great Emperor, he is a strong man in the early stage of the Great Emperor, as long as he waves his hand, he can kill the current one.

Zhang Chen took a deep breath and barely calmed himself down.

"System, what about recycling you just talked about?"

"What good will I get from recycling this black flame?"

"After the system recovers the Holy Relic Emperor Fire, it can feed some of its energy back to the host."

"The host has free rein for these energies."

There was a hint of clarity in Zhang Chen's eyes.

Feed back some energy, but I don't know if these energies can allow him to break through his current cultivation?

"Whew!"

Spit out a breath of turbidity, and Zhang Chen silently chanted.

"System, recycle."
