After all, he had managed to sneak into the ancient underworld with great difficulty. If he left at this time, all his efforts over the years would be in vain.

Fortunately, he cut off one of his souls and had always wanted to contact Duan De's soul.

His purpose was to pass the message on so that the strong people in the fairyland could be prepared so as not to be caught off guard by the weirdness.

“The current fairyland is no longer what it used to be. There are only a few fairy kings, not even quasi-fairy emperors, and it is completely unable to resist weirdness.

"Where is our good brother? Do you have any news about him? If he is here, the monsters will not dare to attack the fairyland!" Duan De asked.

"I don't know where he went. I haven't heard from him for a long time since I came to the ancient underworld!" Cao Yusheng responded.

At this moment, he has realized the seriousness of the matter.

He originally wanted to spread the news so that the strong people in the fairyland could prepare in advance.

But judging from Duan De's answer, the strong men in the fairyland had long been extinct, and even if they knew the news in advance, they would not be able to resist the strange army.

"This is also the reason why we came to you. We want to establish contact with the former Emperor of Heaven through you!" Yang An said.

He didn't interrupt the whole time in order to understand the whole story.

Now, he has understood Cao Yusheng's situation in the ancient underworld and explained their problems directly.

"Want to establish contact with my brother? It is indeed a good idea. If he can return, he can indeed resist the weirdness, but is this too difficult?" Cao Yusheng replied helplessly.

Although he was in the ancient underworld, he also noticed some abnormalities.

He had been trying hard to contact Emperor Huang Tian, ​​but no matter how hard he tried, he was ultimately unable to get through.

In addition, he could feel that the traces of Emperor Huang Tian were gradually disappearing and had even affected his memory.

At this stage, he can't even reveal the real name of Emperor Huang Tian. What this means is enough to fill people with fear.

Although his brother was extremely powerful, this situation always worried him.

“According to our deduction, the Heavenly Emperor has already reached the source of the weirdness and is probably fighting with a terrifying existence.

This level of battle has already transcended time and space, so it is normal that we can't get in touch!" Yang An explained.

He already knew where Emperor Huang Tian was, and even knew what kind of battle Emperor Huang Tian was going through.

It will be a terrible battle unprecedented in history, lasting for several epochs.

No matter how invincible Emperor Huang Tian was, when facing the three strange ancestors, he naturally had no time to take care of other things.

However, there are other reasons as well. If the three strange ancestors could not continue to resurrect, they would have been killed by Emperor Huang Tian long ago.

Emperor Huang Tian had no time to take care of the fairyland, so they could only take the initiative to try to contact it.

"You're right, but I'm afraid you will be disappointed this time. I can't contact him!" Cao Yusheng sighed again.

He has been observing Yang An all the time, after all, he was the one who came to the ancient underworld with his soul.

The cultivation level of Immortal King realm is nothing, but through the description of Duan De's soul, he already knew that Yang An was not simple.

Not only can it easily erase dark matter, it can even erase black blood.

Moreover, Yang An’s several disciples were also very extraordinary. Even in the ancient immortal era where he lived, they were the top geniuses.

In addition, Yang An also has the strength of a quasi-immortal emperor, and can fight against the quasi-immortal emperor of the ancient underworld and gain the upper hand.

All these situations are enough to show how extraordinary the young man in front of us is.

“Of course, we cannot find Emperor Huang Tian through conventional means, so we plan to travel through the long river of time and return to the ancient era of immortals!” Yang An explained.

Cao Yusheng was the key to his plan, so he naturally had nothing to hide and directly revealed all the contents of the plan.

If you want to locate the most accurate era, you naturally need Cao Yusheng's help.

Cao Yusheng's move, combined with his own acquisition of Emperor Huang Tian's hair, is currently the safest way.

“A strong person at the Immortal Emperor level does not need to be bound by time. If you can locate the exact time, it is indeed a good method!

But I don’t know my brother’s condition!” Cao Yusheng said.

It is very clear that the premise of all these plans is to ensure that Emperor Huang Tian is still alive.

If his brother had already died, it would be of no use traveling through time to find him at the right time.

"You don't have to worry about this. Emperor Huang Tian is still alive in this world. I once traveled through the long river of time and met the young Emperor Huang Tian and got his hair." Yang An explained.

He naturally understood Cao Yusheng's concerns, but the desolate world was indeed still alive.

Otherwise, he would not have been led into the long river of time and met the young Emperor Huang Tian.

"You actually got my brother's hair. It seems that, if I take action myself, the probability of success is very high!" Cao Yusheng said in surprise.

As a quasi-immortal emperor, he naturally knew the difficulty of crossing the long river of time. Even a quasi-immortal emperor could not easily travel through the long river of time.

In his opinion, if Yang An is given enough time, his future may even be comparable to that of his brothers!

In addition, he also knew that it was very important to establish contact with Emperor Huang Tian when the weirdness was about to revive.

Without any hesitation, a drop of blood appeared in his hand as he spoke.

If you look closely, you can see that the vitality of the blood is almost overflowing, and it's like a big world inside.

This is Cao Yusheng's blood essence, a drop of blood essence of a quasi-immortal emperor. It contains extremely terrifying power, which can even easily destroy a world.

With this essence and blood, combined with Emperor Huang Tian's hair, he was able to locate the correct time in the long river of time.

“This is my blood essence, combined with my brother’s hair, you should be able to locate the right time.

But I still want to remind you that the long river of time is full of dangers. Even if you have the strength of a quasi-immortal emperor, you must be careful!" Cao Yusheng said.

As a powerful quasi-immortal emperor, he can indeed travel freely in the long river of time, but he cannot interfere with the direction of the long river of time.

If he were to change forcibly, even he would suffer backlash and even end up dying.

There is no wrong version in the 1619 book forum!

Only by reaching the realm of Immortal Emperor can one enter the long river of time unscrupulously and even kill enemies in the long river of time.

He knew that Yang An had experience in going back in time, but his brother was an extremely powerful man, and the stronger he was, the greater the danger.

A slight mistake could cause a huge backlash from the river of time. Even if Yang An possessed the strength of a quasi-immortal emperor, he might end up dead.

“Of course I know this, I will not interfere with history, I am just bearing witness to the past and leaving a mark.

With the strength of Emperor Huang Tian, ​​as long as he leaves a mark, he will definitely be able to establish contact with us!" Yang An said.

He guessed that the current Emperor Huang Tian might have already achieved the level of sacrifice.

Otherwise, even if the three strange ancestors joined forces, Emperor Huang Tian would not be able to fight with the ancestors for such a long time.

In fact, he doesn't need to take the initiative to look for it. He just needs to appear at the right time and Emperor Huang Tian will sense it.

With Emperor Huang Tian's current power, even if there are endless years and countless worlds between us, as long as Emperor Huang Tian wants, he can find me.

"Since you already have a plan and know that the weirdness is about to revive, leave quickly!" Cao Yusheng drove them away.

The ancient underworld is filled with strange substances and black blood, which is extremely dangerous. The longer you stay here, the more dangerous it becomes.

"Before I leave, I have one more question I want to confirm!" Yang An said.

He had finally met Cao Yusheng, so he naturally couldn't leave easily.

Cao Yusheng has been dormant in the ancient underworld for countless years, so he should be able to answer some of the questions in his mind.

"Ask quickly and leave after you're done!" Cao Yusheng was already getting a little impatient.

"I want to confirm which strange creature is presiding over this grand sacrifice." Yang An asked.

When he first faced the weirdness, he already knew that the grand sacrifice was about to take place.

The strangely launched grand sacrifices have occurred countless times in the heavens and all realms. Each time it was an unimaginable disaster, and countless lives would perish.

But few people know that every grand sacrifice requires a main priest, who usually comes from one of the four bridgeheads.

Although he already had some guesses about the chief priest in his mind, he wanted to get the exact answer from Cao Yusheng so that he could make better preparations.

When he heard about the grand sacrifice, Cao Yusheng looked at Yang An with some surprise, not understanding why Yang An knew all this?

"It seems that you know a lot of secrets, but this is not a secret. I can tell you that this grand ceremony will be presided over by Hunhe!" Cao Yusheng replied.

He knew very well that since Yang An asked such a question, he must know what the grand sacrifice meant.

Not to mention in the fairyland, even in the heavens and myriad worlds, there are very few people who know about the grand sacrifice.

Moreover, after each grand sacrifice, all realms turned into nothingness and all living things withered, so naturally no one would know about it.

The fact that he knew about the grand sacrifice already showed how extraordinary Yang An was. What's more, Yang An also asked where the grand sacrifice would be presided over.

This means that Yang An not only knows about the great sacrifice, but also has insight into the truth behind the great sacrifice and has been exposed to strange secrets.

"It is indeed the Soul River! It is consistent with my guess. It seems that the war is inevitable!" Yang An thought to himself.

Cao Yusheng's answer was exactly the same as his guess, and made him realize the urgency of time.

In the original history, the great sacrifice launched by the Soul River was extremely tragic, and even the Emperor Wu Shi eventually died in it.

In order to stop the weirdness, the battle at Soul River is inevitable, but with his participation, there is still a chance to reverse the outcome.

Yang An had already gotten what he wanted and the answers he wanted, so he naturally would not stay in the ancient underworld for long.

After thanking Cao Yusheng, he and Duan De set off to return to the fairyland. (End of this chapter)
