Walking into the black portal, Zhang Chen did not feel the dizziness he had when he had passed through the space passage before.

This black portal is like a real portal.

Except that you can't see anything after entering, it's no different from a normal portal.

"Da! Da! Da! ”

Inside the black passage, there was only the sound of footsteps.

Zhang Chen and Zhang Daotian held hands to prevent accidents.

I don't know why, but the power of divine thoughts cannot be used here, and I can only rely on the sense of touch to confirm that each other is not around.

I don't know how long I walked, but finally, a bright light appeared at the end of the endless darkness.

Seeing this, Zhang Chen said in a deep voice.

"I'm going to the inner part of the secret realm soon, pay attention to the surroundings!"

Zhang Daotian and the five of them didn't answer, but the palms of the hands holding each other tighter.

Walking out of the darkness, Zhang Chen's brows furrowed slightly.

Because he felt an unusual energy all around him!

This energy is not Reiki, but an unknown energy!

At this moment, the system prompt sounded in Zhang Chen's mind.

"It is detected that the host has entered the Great Emperor Inheritance World Ten Thousand Martial Ancient Realm, which meets the system standards, and activates a sign-in opportunity."

"May I ask the host, do you want to check in?"

Wanwu Ancient Realm?

Is this the name of this Inheritance Realm?

Zhang Chen did not sign in immediately, the most important thing at this time is to be familiar with the surrounding situation.

Glancing around, Zhang Chen found that they had come to a palace.

The place they had just walked in had been turned back into a rock wall, and only the occasional inscription showed that it was unusual.

There was nothing in the palace except them, not even Hua Tian and the others, who had entered first.

The palace gates opened, proving that they had left first.

After Zhang Chen found that there was no danger, he breathed a sigh of relief slightly, but his brows were still furrowed.

"Although there is also aura in this palace, it is relatively thin."

"The most intense is an unknown energy that has never been seen before!"

His eyes fell on Zhang Daotian and the five people, and Zhang Chen's face showed an inquiring look.

"Do you know about this energy?"

Zhang Wanzhao and Zhang Cang also sensed that the energy around them was different from that of Kunpeng Ruin, and shook their heads in confusion.

"Your Highness the Divine Son, we don't know either."

Zhang Chu and Zhang Wenxuan frowned, and also shook their heads.

"This kind of energy has never been seen before, and it is even more destructive than that of Reiki."

"It's just that, this kind of energy is too violent, although it is full of destructive power, it does not have the rich vitality of the aura."

"If you absorb this kind of energy to cultivate, the combat power of the same realm will increase, but the lifespan will be greatly reduced."

Zhang Chen nodded in agreement.

"Yes, I also perceive that it is more destructive, but it lacks vitality."

"If you use this energy to break through to the Saint King Realm, it is estimated that you will only have a lifespan of one or two thousand years, which is ten times faster than that of a spiritual power cultivator."

The monks of the Northern Netherworld Realm, the powerhouses of the Saint King Realm, can almost survive for 200,000 years.

It is far from being comparable to the 20,000-year lifespan.

This kind of energy is very strong in combat, but it is exchanged for longevity.

Compared to this unfamiliar energy, Zhang Chen was more willing to cultivate aura.

At this time, Zhang Chen found that Zhang Daotian frowned and didn't say a word, as if he was thinking about something.

"Brother Daotian Clan, what do you know?"

Zhang Daotian nodded slightly, his brows still furrowed.

"I do have some speculations, and I can't hide it, I had an adventure in the Kunpeng Ruins in my early years, and it was a monument."

"That monument was left in the Kunpeng Ruins by a powerhouse from the primeval period, and I learned from that monument that aura is not the only cultivation energy!"

"Before the endless years, there were other energies competing with the aura, and countless cultivation paths were derived."

"It's just that there are more and more spiritual qi in the world, so that the spiritual energy cultivation method occupies an orthodox position, and the rest of the cultivation methods are gradually eliminated until they disappear!"

When the words fell, Zhang Chen's pupils shrank suddenly.

In addition to spiritual power cultivation methods, there are other cultivation methods!

They had never heard of this secret.

Zhang Daotian took a deep breath and said in a deep voice.

"I suspect that this extremely destructive but lifeless energy around us is the cultivation energy second only to the aura before the endless years."

"This energy is called Xuanqi! In the description, Xuan Qi has the ultimate destructive power, but the vitality is lacking. ”

Xuanqi?

If nothing else, the surrounding energy should be Xuanqi.

Zhang Chen's pupils became deep.

It is called the cultivation energy second only to the aura, and if you really want to talk about it, the aura and the energy around them can be regarded as having their own merits.

The vitality of the aura is more intense, and it is easy to live a long life when cultivating.

The energy around it is full of destructive power, which is more suitable for the pursuit of ultimate power.

Zhang Chen looked at Zhang Daotian and asked.

"Have you ever known if the place where this endless years ago was located was the Northern Netherworld Domain?"

If there were countless cultivation paths in the Northern Netherworld Dao Domain before the endless years, both the aura cultivation method and this Xuan Qi cultivation method existed.

Then the possibility that this Wanwu Ancient Emperor came from other new worlds would be extinguished.

Zhang Daoyou shook his head.

"Your Highness the Divine Son, that's all I know from the monuments, and that monument is incomplete and most of it has been destroyed."

"From those few words, I have summed up the information just now."

"Somewhere a long time ago, there were countless cultivation methods, and finally the world evolved to allow the aura cultivation methods to dominate and win a big victory."

"More, I don't know at all."

When Zhang Chen heard this, he felt a little regretful.

If there is more information, then it can be directly judged whether this Wanwu Ancient Emperor is the Great Emperor powerhouse who existed in the Northern Netherworld Dao Domain before the endless years.

Now that the information is insufficient, the origin of the Wanwu Ancient Emperor is still a mystery.

Even combined with the surrounding Xuan Qi, Zhang Chen had a feeling that perhaps this Wanwu Ancient Emperor was from a world that majored in Xuan Qi.

Shaking his head, Zhang Chen restrained his emotions and said in a deep voice.

"Our exercises are not in harmony with the Xuan Qi, don't absorb these Xuan Qi around us."

"Next, there will be battles that will consume spiritual power, and use pills or heavenly treasures to recover."

Zhang Daotian and the five of them glanced at each other and nodded solemnly.

"Your Highness the Son of God, you too, be careful."

Zhang Chen turned around and looked outside the main hall.

"Let's go along and take a look, this secret realm is the emperor's secret realm after all, don't let those guys rob up the good things!"

After speaking, his body moved first and flew outside the main hall.

Zhang Daotian's expressions froze, and they also followed.

Indeed, now is not the time for them to dwell on these things, and it is imperative that they keep up with the large forces and make reasonable use of those three priority selection privileges.

As Zhang Chen said before, we can't let those three priority selection privileges go to waste.

After Zhang Chen and the others left, the hall regained its tranquility, and only inscriptions appeared from time to time, adding some vitality to the hall.

……

Walking out of the main hall, Zhang Chen and the others came to a complex building complex.

The style of these buildings is more crude and wild than that of the Northern Netherworld, and there is no sense of detail at all.

In front of a palace-like building not far away, Zhang Chen and the others saw Hua Tian and the others again.

Zhang Chen suppressed the system prompt sound that kept ringing in his mind and looked in the direction of Hua Tian and the others.

In front of Hua Tian and them, there seems to be a strong prohibition.

Inside the forbidden area is a medicinal field, which contains countless heavenly treasures that exude a rich fragrance.

Seeing these heavenly treasures, Zhang Chen's expression froze.

"Ten Thousand Years Treasure Medicine!"

The elixirs in that medicine field are actually all 10,000-year-old elixirs!

The lowest years are at least 30,000 or 40,000 years old!

And there are hundreds of elixirs in that medicine field, to say the least!
