Immortal cultivation starts with copying.

When Chen Yunhao followed the crowd to a sea area, thousands of people had already gathered there, and countless sirens were hiding under the sea.

This is an empty sea area with no islands around, but what attracted Chen Yunhao's attention was the empty sea area in front.

There stood a particularly majestic palace in the void, so magnificent that it looked like a mirage from afar.

The feeling of shock became even stronger when you got closer. There were eight large pillars in front of the palace, and the closed double doors alone were thirty feet high.

A heavy sense of vicissitudes, simplicity and mystery comes to you.

Thousands of monks have arrived at the scene, some in groups of three or five, some standing alone, and they can also see flashes of light coming from the distance from time to time.

However, the scene was clearly divided, with several old monsters in the Nascent Soul stage standing in the front.

Next came the Jindan stage, and further out were the foundation-building stage. The Qi-refining stage cultivators all stood at the farthest point, not daring to come forward at all.

Looking at the situation in front of him, Chen Yunhao knew that this should be a secret realm or an ancient cave.

But he didn't know what it was exactly, so Chen Yunhao didn't dare to rush into the crowd.

At the outermost edge of the crowd, he stopped a newly arrived Qi Refining cultivator.

The cultivators in the Qi Refining Stage either come here with the cultivators in the Foundation Establishment Stage.

Anyone who came alone was extremely brave, and they all rode on flying magic tools, rushing over in a dusty state.

"My dear little brother, I am a cultivator from the Black Turtle Sea. I am passing by here. Has this cave been created?"

"Senior, this is Tianyan Mansion. It appears once every sixty years. The exact location of its appearance is uncertain, but it could be anywhere in the Boundless Sea. I didn't expect it to appear in our Cancer Sea this time. What luck...!"

The young Qi Refining cultivator who was stopped by Chen Yunhao spoke to Chen Yunhao respectfully, but his face was full of excitement as he kept glancing at the huge palace.

"Tell me more about it in detail..."

As Chen Yunhao spoke, he took out a bottle of Lingxia Dan that he had made and threw it to the Qi Refining cultivator in front of him.

This Lingxia Pill is worthless to Chen Yunhao, but for a cultivator in the Qi Refining Stage, it is an unexpected gain.

"Thank you, Senior..."

The young monk happily put away the elixir.

"This Tianyan Mansion appeared very long ago, and the exact age is no longer verifiable..."

As the young cultivator continued to tell his story, Chen Yunhao roughly understood what was going on with the cave that appeared before him!

It is said that Tianyan Mansion does not belong to this world, but should be something from the upper world.

For unknown reasons, it drifted to the lower world and would randomly appear on the boundless ocean every sixty years.

Moreover, the gate of Tianyan Mansion will be opened two days after its appearance, and this gate will only last for one day, after which it will be closed and disappear again.

From the outside, it looks like a continuous palace, but once you really go inside, it is another world, probably a small world or something like that.

The monks who enter will be assigned to different areas according to their cultivation level.

There is no upper limit on the level of cultivation required in the Tianxian Palace. Anyone can enter, whether they are in the Qi Refining Stage or the Spirit Transformation Stage.

The cultivators who enter can only stay there for seven days, after which they will be sent out directly by Tianyan Mansion.

As for the location where it was sent out, it is not the place of entry. It may still be in the Cancer Sea, or it may span several seas.

Because Tianyan Mansion has appeared more than a thousand times, countless cultivators have entered it.

Therefore, some news about the internal affairs of Tianyan Mansion was also widely circulated.

It is said that although it is extremely dangerous inside, the rewards are huge.

After all, it is an existence from the upper realm. Some cultivators have obtained heavenly-level skills in it and have soared to the sky since then.

Some of them obtained elixirs that were only available in the upper realms, and eventually became Nascent Soul ancestors.

Some monks also obtained spiritual weapons and were invincible in several sea areas.

This is beneficial, but no one cares about the monks who died inside.

It is said that the number of people entering Tianyan Mansion each time varies, ranging from thousands to tens of thousands.

But in the end, only one in ten can come out alive, and high rewards also mean high risks.

This is a simple truth that everyone who cultivates immortality knows, but greed is insatiable!

Especially for most of the independent cultivators, no matter how hard they try to cultivate, they will still be mediocre all their lives. Instead of ending up in dust, it is better to go in and fight for a vast world!

After getting a general understanding of the situation in Tianyan Prefecture, Chen Yunhao was a little hesitant.

He is different from ordinary casual cultivators. He has earth-level skills, excellent spiritual roots, and an ancient mirror, which is a heaven-defying treasure.

So he doesn't need to risk his life for a bright future like others, which is why he hesitates.

If the monk had no adventurous spirit, he would never reach the final destination.

But this adventure is not a reckless rush, but a decision made after weighing the pros and cons.

It is not wise to rush forward knowing that you will die!

Chen Yunhao was hesitant at the moment, but in another day, the gate of Tianyan Mansion would be open, so he would decide then.

During the waiting time that followed, monks rushed over from afar every moment.

There were also undercurrents surging under the sea, and some sirens in the demon pill stage and the transformation stage had already hidden in the deep sea.

Not only humans can enter Tianyan Mansion, but monsters can enter as well. There are no restrictions.

As for who lives and who dies, that depends on one's personal means and luck.

Chen Yunhao found a place with few people and stood there silently.

Sometimes he doesn't know whether he is lucky or unlucky.

Generally speaking, luck is a plus. He happened to encounter something that only happens once in sixty years in the Boundless Sea. No matter how you look at it, he is a lucky man!

But even if you have good luck, you can't be blindly confident. Chen Yunhao is a cautious person. Anyway, this time he will just watch the fun. The chance of not getting in is relatively high!

By the evening of the second day, at least 20,000 to 30,000 monks had arrived in the entire sea area.

The Cancer Sea and the surrounding sea areas are mainly human-populated areas with many monks. It is not too many to have so many monks coming in two days.

When night fell, a loud bang was heard and the scene of tens of thousands of people suddenly became silent.

The huge palace gate slowly opened, and behind the gate was pitch black, like an endless starry sky, a void.

The door was only about one-third open, and the dozen or so old monsters in the Nascent Soul stage standing in the front couldn't wait to rush in.

There was a loud sound of splashing water, and more than a dozen sirens in the transformation stage who had been hiding under the sea also rushed in.

Seeing someone taking the lead, the Jindan stage cultivators could no longer hold back. Thousands of rays of light flew into the pitch-black gate one by one like meteors.

By the time all the Jindan cultivators had left, the gates had all been opened.

The remaining Foundation Establishment and Qi Refining cultivators did not follow so many rules, and they all rushed to Tianyan Mansion.
