It was heavily guarded, and every soldier was wearing armor all over his body, so he couldn't see his face clearly, but his body was filled with a fierce aura.

Just from the aura released invisibly, Chu Nan estimated that these soldiers were at least gold-level peak existences, and even platinum-level powerhouses!

"It's too strong!"

Chu Nan was horrified in his heart.

The Heavenly Desolate Empire is worthy of being the Heavenly Desolate Empire, and even the soldiers are gold-level peaks, platinum-level existences. Of course, it is mainly because this is the entrance to the underworld that these heavy troops will be sent to guard it.

But despite this, Chu Nan was also frightened by the background of this Desolate Heaven Empire.

In the past, when he first came out of Arashiyama City, he thought that among the major forces in this empire, the platinum level was already the existence of the top sky, but as his cultivation became more and more powerful, he found that things were far from the case.

The platinum level may be a threshold to enter the circle of powerful people in this empire.

......

And in this heavily guarded place, there is a towering black tower, the tower is completely black, I don't know what material it is made of, but it makes people feel a feeling of palpitations.

The black tower in front of him was like a desolate beast roaring towards the sky.

After Zhou Tianci came to the front of the black tower, he put a token into a slot above the door, and suddenly, the door slowly opened.

Chu Nan looked surprised from behind, but these people around him seemed unfazed, it seemed that they had already been here many times.

Chu Nan suddenly thought of a question, so he couldn't help but ask Luo Yan on the side: "By the way, it's not that the tasks in the underground world are rich in rewards, logically speaking, there should be a lot of people here who go to do tasks?

Luo Yan replied in a low voice: "Brother Chu Nan, in fact, although the palace tasks are rich in rewards, they are limited, originally these tasks were used to experience the prince, but in the past, many princes who were a little less powerful would invite some powerful disciples of the sect as helpers, and over time, they evolved into what they are now." ”

After hearing this, Chu Nan suddenly realized: "It turns out that this is the ......"

At this time, Luo Yan said again: "Moreover, during this period of time, there have been some abnormal changes in the underground world, and many princes have also suspended their missions, so it is like what I see now......

After hearing this, Chu Nan was taken aback.

Indeed, their cultivation is definitely the top layer among the younger generation, and in this extraordinary period, only a talent like Zhou Tianci would dare to take on the task.

However, Chu Nan still asked, "What kind of mutation is it?"

"Almost. ”

Luo Yan nodded: "That matter involved the demons underground, so many princes stopped. ”

The strength of the underground demons, invincible at the same level, once the ordinary monks encounter it, they are simply crushed, even if there are many people, only them, who are in the same level, are in the top layer, and they have the strength to hunt the underground demons, of course, just hunting, the same realm, single, human beings are not the opponents of the underground demons at all.

......

As the group entered the Black Tower, Chu Nan saw that on the first floor of the towering Black Tower, there was an ordinary-looking ancient well in the center.

The moment he saw this ancient well, Chu Nan's face changed.

He had seen this ancient well before!

It was in the realm of ethereal spirit painting, in the ruined ancient city, a mysterious ancient well, and there was a small black tablet next to it, and there were many terrifying and abnormal things at that time.

"This ......"

Chu Nan had a lot of speculation in his head for a while.

"Could it be that what is in the ethereal painting realm is not the truth of history, but the prediction of future history?

After all, this kind of ancient well is not common, and Chu Nan is very sure that the ancient well in front of him is really exactly the same as what he saw in the Void Spirit Painting Realm at the beginning.

Moreover, later in the ancient tower of the snow field, Chu Nan once saw a prediction about his old age, and when he thought about it, he was suddenly terrified.

There is a real possibility that the scene in there is not a corner of the truth of history, but some kind of prophecy......

......

"Chu Nan, what's wrong with you?"

Luo Yishu, who was next to him, saw that Chu Nan suddenly stayed in place, and his face looked very frightened, so he hurriedly shook his arm.

"Oh...... It's okay. ”

After Chu Nan came back to his senses, a layer of cold sweat broke out on his back.

Then, he looked around the ancient well, looking for the mysterious black tablet.

At this time, Zhou Tianci had already arrived in front of the ancient well, and then, he took out a sharp knife and swiped it lightly towards his finger, and a drop of blood dripped into the ancient well.

Airplanes!

Suddenly, the ordinary-looking ancient well, at this moment, there was a huge movement.

A pitch-black mist came out of it, and when it poured in, everyone seemed to hear the roar of the devil in it.

Although they have seen this scene a lot, after encountering it again, everyone still can't help but change their faces slightly.

"Black Mist?"

When he saw the black fog, Chu Nan was startled again.

However, he sniffed it lightly and found that this black mist was not the black mist he had encountered in the Ethereal Spirit Painting Realm, and the essence of the two was not the same.

This kind of black fog has a taste of "creation".

As for what the taste of creation was, Chu Nan had felt it.

At the beginning, when the gold medal instructor Chu Jianshan was guiding them in the Drum Peak, he had shown the means of creation, and there was a special aura in it, which was faintly revealed by this black mist.

But on the top of the ancient well, the black mist gradually condensed.

Like a devil with teeth and claws.

But after a while, these black fogs gradually stabilized, scattered and condensed, and actually took on the appearance of a portal.

In this portal, the black mist condensed into a whirlpool, and when people looked at it, they felt that their spirits and souls were sucked in.

"Let's go, let's go in!"

As Zhou Tianci said this, he took the lead in jumping into the whirlpool of black mist condensation, and suddenly, his figure disappeared as if it had been swallowed by the mouth of some fierce beast.

The rest of the people were obviously used to it, and they followed behind Zhou Tianci without hesitation, and jumped into the black mist portal one after another.

......

Gradually, Chu Nan became the last.

He did not rush into the whirlpool, but secretly probed and observed the ancient well, and even searched for a while nearby.

I found that the ancient well was the same, but there was no black tablet here that I had seen in the Ethereal Spirit Painting Realm, and the speculation in my heart suddenly became confusing again...... Emperor Ou spared his life
