After the death of the dark and turbulent patriarch, he actually asked me to dig out the forbidden a

After following Su Wen and getting acquainted in the mansion for a few days.

Ning Chen also settled down in this Baiduan family.

After being familiar with it for a while.

Ning Chen also slowly learned about why the heavens and spirit worlds are divided into four great immortal emperors.

Actually.

In that fairy world.

The powerhouses at the first level of the Immortal Emperor are actually not in the minority.

Even, it can be said that in today's fairyland.

A powerful existence at the level of an immortal emperor exists in almost every transcendent, powerful ancient clan.

only.

This is a powerful existence at the level of the Duofang Immortal Emperor.

But they also have to obey the orders of the Four Great Immortal Emperors.

It is said that it was hundreds of millions of years ago.

A mysterious secret realm descended from the fairy world.

It's called Daoyuan!

In this abyss of mystery.

There are many strong men in the fairy world.

You can step into it and seek a more powerful force.

In the end, there were only four people who got that powerful power almost every time!
Although these four are strong at the level of Immortal Emperors.

But it is to control the power beyond the level of Immortal Emperor.

Therefore, it is possible to rule all directions.

Even spread the hand of control to the heavens and spirit worlds.

And, according to the record.

It seems that all of this is related to a dark turmoil that once swept the heavens!

Mind this.

Ning Chen also probably knew.

This is the so-called Dao Yuan.

Who is left behind.

Moreover, the four great immortal emperors each pass [-] million years.

It will be replaced.

At that time, when Daoyuan reappeared, all directions would be shaken.

Between heaven and earth, there will be a brand new dark turmoil.

Endless fighting, the end of the battle.

The four people who obtained the mysterious power in Daoyuan will reproduce the power that divides the fairy world.

And behind all this.

What the hell is it for.

Why does Daoyuan cause turmoil in the world every time [-] million years pass, causing boundless killings.

No one ever thought about it.

Ning Chen was also puzzled by this.

It started when Ning Chen had acquainted with the mysterious existence in the dark.

This person has been constantly launching dark turmoil, causing massacres again and again.

So much so that an unknown number of creatures have fallen into it between heaven and earth.

His purpose is really hard to guess.

In desperation.

Ning Chen stopped thinking about it.

Also after three days.

On this day, Su Wen came to inform Ning Chen.

You can go to the Cangjing Pavilion to check the experience of ancient books.

Therefore, Ning Chen followed him to the depths of this magnificent mansion.

The mansion of the Baiduan family can be said to be heavily guarded.

Except for the uninterrupted guards for twelve hours.

There are also countless prohibition formations hidden in this mansion.

If it wasn't for practicing Dayan Puppet Art, the divine sense is extremely powerful.

Maybe Ning Chen couldn't discover so many mysteries at all.

now.

The two walked through the mansion.

It took about several hours of work.

Finally came to a certain hall in the mansion.

Here, apart from the heavily guarded guards, there were not a single disciple of the Baiduan family that could be seen everywhere.

Moreover, around this hall, there are even more powerful restrictions hidden.

Obviously, it was guarding against someone sneaking into this place secretly.

At this moment, Baiduan Tushan had been waiting on the main hall for a long time.

After seeing the two of them, he said to Ning Chen with a smile on his face:
"Little friend, you should remember some experience, don't waste time!"

Ning Chen nodded slightly, and naturally said:

"It's natural."

Afterwards, Baili Tushan waved his hand, and in the blink of an eye.

Hundreds of top-grade immortal stones suddenly floated out from his palm.

In an instant, it fell into the huge formation above the ground of the main hall.

buzzing~~~
With bursts of roaring sounds.

Above the main hall, even the slightest spatial fluctuations gushed out!

Then, a burst of mysterious light lit up.

Immediately, a huge teleportation array was completely activated by it.

Baiduan Tushan signaled, and Ning Chen followed him into it.

It was just after a while of teleportation.

Ning Chen and Na Baiduan Tushan then came to a secret space.

Waiting for Ning Chen's divine sense to sway, he examined it carefully.

But I discovered that this place turned out to be a small world!

"The methods of the Baiduan family are really extraordinary, they are able to open up such a small world."

At this moment, Ning Chen couldn't help but sigh.

The Small Thousand World is the world in the Great Thousand World, that is, the world below the first-class plane of the Pangu Realm.

Often such a world is not stable.

It will last for a few million years at most, and then it will dissipate on its own.

Among them, life will not even be born.

Naturally, some powerful faction groups.

If you want to preserve something or the existence of ancient books, exercises and so on.

In fact, the best way is to open up a small thousand world by yourself.

used for storage.

The small thousand world in front of me is just like that.

Baiduan Tushan smiled lightly, but led Ning Chen towards a tall tower ahead.

Around the tower, there are many various buildings.

And in these buildings.

Ning Chen could sense the presence of some powerful auras.

Obviously, even here, there are masters sitting in charge.

"Little friend, after entering, you have one year to look up your experience in it. After one year, the old man will remind you to come out. During this period, the old man will wait here for you."

After Ning Chen nodded slightly.

and headed for the black tower,

Take a closer look.

Ning Chen found out.

This black tower turned out to be very similar to the black tower of the Artifact Refiner's Guild.

It's just, the black tower of the craftsmen's union.

Compared with this black tower.

But it is very different!

"This black tower is probably already at the level of a fourth-grade fairy weapon!"

At this moment, Ning Chen carefully checked the formation level on the black tower.

For a moment, he couldn't help but sigh with emotion.

Around the black tower, there is not a single guard guarding it.

And the surrounding guards are all far away from the black tower.

It's as if, in this black tower, there is an ancient beast imprisoned.

daunting.

Simultaneously.

The first time Ning Chen came to the black tower.

I also felt a weird feeling.

"It seems that there is a familiar feeling!"

Because of the self in the previous second life.

He has intervened in many things in the heavens and spirit world.

At this moment, Ning Chen felt an inexplicable familiar feeling beside the black tower.

all of these.

This place seemed to be the place Ning Chen had been to in his previous life.

But if so, the system should respond!
With full of doubts.

Ning Chen stepped into it slowly.

but.

It also followed Ning Chen into the black tower.

Under this black tower.

In a dark abyss.

a mysterious existence.

It was the pair of eyes that were as huge as mountains that opened
