On the way back to the Immortal Realm, Wang Xuan has been thinking about a question, what kind of existence is the ancient underworld, and who created it.

Obviously, the ancient underworld was not formed by heaven and earth, but by the handiwork of one person. It is not difficult to guess who this person is.

Except for the most powerful man in history, looking at countless worlds, absolutely no one can create a place like the ancient underworld.

Why did the other party create the ancient underworld? Was it to create real reincarnation? Or did it have other unknown purposes?

Everything disappeared with the passing of that invincible strong man, and the purpose of the existence of the ancient underworld can no longer be traced.

In those endless years, before Weirdness had yet to arise, the Ancient Underworld might have changed many owners.

Of course, even Weird cannot fully control the ancient underworld, and it is even less possible for these nominal masters to control the underworld.

But these nominal owners have left immortal traces here, making the true face of the ancient underworld even more difficult to trace.

The reason why he asked whether Weiyi had completely controlled the ancient underworld was not because he wanted to know the answer, but to see if Cao Yusheng knew the answer.

Obviously, Cao Yusheng knows the answer, which means that Cao Yusheng already occupies an important position in the ancient underworld.

If there is anything Duan De is best at, it is naturally digging along the way. This is true in the human world, and it is also true in the fairyland.

As Duan De's true form, he is better than his master. This is what theory should do. Maybe he can dig out some secrets in the ancient underworld.

This is a place created by an invincible strong man. Even the smallest secret is an unimaginable creation for anyone.

In the original plot, Cao Yusheng struggled to find the person he longed for, but he was still unable to break through to the realm of the Immortal Emperor.

This is not the right choice. He should have a longer-term vision. After all, as long as he is strong, he can completely resurrect the past people.

Before leaving, he actually made it clear enough. Whether Cao Yusheng can understand or continue to go his own way depends on his own destiny.

Now his strength is still far behind. When his strength improves in the future, he will definitely come to the ancient underworld to pursue the buried secrets.

After returning to the Immortal Realm, Wang Xuan began to travel through time. When something strange was about to happen, the sooner the better.

However, it is not an easy task to penetrate the long river of time and return to the chaotic ancient times long ago.

Even powerful people at the level of quasi-immortal emperors cannot manipulate the river of time at will, and cannot go to the time node they want to go at will.

The most important thing is that Wang Xuan and others are not quasi-immortal emperors yet, they are just a group of immortal kings, which is naturally difficult to achieve.

To do this, you must find special nodes, and then use the power of the entire world to penetrate the long river of time.

This is actually somewhat similar to the road to immortality in the past. Only at the right time and at the right place can you meet the right person.

This is not a big problem. Whether it is Wang Xuan, Ye Fan, or Duan De, they are all masters in Origin Technique.

Find special nodes, lay out amazing terrain, and use the power of heaven and earth to help them penetrate the long river of time.

"Master, going through the long river of time and traveling to a distant era is beyond the reach of heaven. Let us take action!" Ye Nannan said with a solemn expression.

The others also looked solemn. Traveling through time was not something the Immortal King should do at all.

Although they are all unparalleled talents, each of them is extremely confident, but they cannot guarantee that they will not be lost in the endless river of time.

The safer way is to wait until the quasi-immortal emperor to travel through time, so that safety can be guaranteed.

"It's okay! You don't need to take action this time. I'm just going to explore the path first and evaluate the difficulty of traveling through the long river of time!" Wang Xuan said.

How could he not know how difficult it would be to travel through time at this time, but now the arrow was on the string and he had to take action.

Breaking through to the realm of the quasi-immortal emperor will not be achieved overnight. By the time they break through, the strange creatures will probably be almost ready.

At that time, although it will be more secure to travel through the long river of time, powerful strange creatures will definitely intervene.

This is not an exaggeration. They traveled through the long river of time in order to contact the Emperor of Desolate Heaven, and the powerful and strange creatures would definitely be affected.

Even if you are a powerful person at the level of a quasi-immortal emperor, fighting in the long river of time will be extremely dangerous, and you will get lost if you are not careful.

Moreover, when that time comes, whether they still have the chance to travel through time is a question.

Although it was dangerous now, at least there was no one to disturb him. He could try slowly and find a suitable path.

"I'll go with you. After all, I have a close relationship with that person. Maybe I can get something unexpected!" Duan De said in a deep voice.

This time he went to the ancient underworld. In addition to finding his own body and knowing many secrets, he actually gained other things.

With the help of his true body, he has successfully broken through to the realm of the Immortal King, and is now qualified to travel upstream through the long river of time.

This is something that others cannot envy. After all, Duan De and Cao Yusheng come from the same origin, and they can be integrated into each other.

After fusion, you can share realms and cultivation experience. Cao Yusheng is now a quasi-immortal emperor, and Duan De's cultivation level is naturally rising.

It is foreseeable that for a long time in the future, Duan De's cultivation will improve rapidly and he will continue to approach the quasi-immortal emperor.

Even if Duan De breaks through to the realm of quasi-immortal emperor before Ye Fan and others, it is not an exaggeration.

It is precisely because of the experience of practicing the original body that Duan De has the confidence to make such a decision and prepare to travel through the long river of time with Wang Xuan.

"In that case, then you will go on the road with me, go upstream along the long river of time, and go to different time nodes!" Wang Xuan thought for a moment and said.

He knows very well that this time there is a high probability that he will just try it first, and it will be difficult to successfully locate the right time node in one go.

Time is unpredictable, and even with a drop of Cao Yusheng's blood to guide them, the most they can do is go to the era of Emperor Huang Tian.

But whether it was when Emperor Huangtian had just embarked on the path of cultivation or when Emperor Huangtian had not yet become an immortal was something that was unpredictable.

What they are looking for is Emperor Huangtian who has just become the Immortal Emperor. In the vast river of time, he is equivalent to a drop of water.

How difficult is it to find a special drop of water in the ocean? Just thinking about it can make one's scalp tingle.

At this time, Duan De already had the cultivation experience of the original body and had a deep connection with Emperor Huangtian. In fact, he was the most suitable candidate to travel through the long river of time.

But even if Duan De takes action himself, it is difficult to guarantee that he will be able to find Emperor Huang Tian at the right time. Everything depends on luck.

"You must be careful, even if you just travel through the long river of time, it will cause unpredictable consequences!" Jiudaoyi said in a deep voice.

He and the other three veterans had to lament that today's young people are so powerful. They are just immortal kings and dare to travel through time.

Not to mention, these young people have to search for a powerful person in the long river of time, and the cause and effect involved is too great.

If you are not careful, you will be completely lost in the long river of time. This is by no means a lie, but something that will happen with a high probability.

When Ye Fan and others saw that their master was paying attention, they didn't have much to say, but their hearts were very heavy.

They know very well that everything is because their own strength is not strong enough. If they are strong enough, why should their master be like this?

If they were all quasi-immortal emperors now, they could all enter the river of time. Why would they need to take risks like now?

This feeling is not pleasant. Ye Nannan and others have secretly vowed in their hearts that they must practice hard and break through to the realm of quasi-immortal emperor as soon as possible.

"Don't worry! Come with me now and penetrate the long river of time. Whether I can return safely depends on you!" Wang Xuan said in a deep voice.

They have found a special node in the Immortal Realm, and have laid out a shocking terrain, and have a large formation that can mobilize the power of heaven and earth.

But this is still not enough. Everyone needs to work together and gather all their strength to truly penetrate the long river of time.

After Wang Xuan enters the river of time, Ye Fan and others will still need to protect this place and not let it be destroyed.

Otherwise, when Wang Xuan returns from the long river of time, he will not be able to find his way back, and will eventually be completely lost in the long river of time.

Moreover, if the river of time is touched and a strong person with cause and effect is induced, the other party can also follow the river of time to kill.

And the strong men at that level will at least start out as Immortal Kings, and there is a high probability that they will be at the level of Quasi-Immortal Emperors, and there may even be Immortal Emperors.

When Wang Xuan travels through time, this place is not allowed to be destroyed. Therefore, Ye Fan and others have a very heavy task.

After preparing everything, everyone took action at the same time, using the Mother Qi Cauldron of All Things, the Wu Shi Bell, the Void Mirror, etc. across the sky to strike an unparalleled blow.

A group of Immortal Kings took action, which was already terrifying. In an instant, the world trembled and was torn apart, and a huge gap appeared.

With a "poof" sound, the fairy light surged, and then a great river surged out. The power was so powerful that it caused chaos in the rules of the avenue and unstable order.

The combined blow of everyone tore apart time with incomparably powerful force, causing the world to tremble, and the long river of time to surge forward.

Looking at the endless river of time, everyone has fear and expectation on their faces. This is the long river that runs through the past, present and future.

Theoretically speaking, if you go upstream in this river, you will go to the distant ancient times and see those people and things that have disappeared.

If you go straight down the long river of time, you will go to the unpredictable future, and you may be able to see what will happen in the future.

But this long river of time is also very unusual. A powerful person once said that if you mess with the long river of time at will, you will eventually be played with by time.

Therefore, even an extremely powerful person can only travel through the long river of time to witness, but dare not interfere.

Wang Xuan nodded to Ye Fan and others, stepped out, and entered the long river of time. Duan De also gritted his teeth and followed closely.

The moment they entered the long river of time, both of them felt a vast force, so shocking that it was almost irresistible.
