Walking into the canyon, there was a clicking sound under his feet. Fade Chen looked down and couldn't help being surprised.

Because, at this moment, under his feet, there is a layer of white bones.

Because of the age and sea water, the bones were soaked very fragile, and when Fade Chen stepped on them lightly, they shattered.

And judging from the shape of the white bones, most of them are various sea beasts, with some human skeletons vaguely mixed in.

"This holy place is a bit special!"

Fade Chen muttered, exerted a little force, let his body volley, and continued to move forward.

Walking to the end of the canyon, an entrance about the height of a person appeared in front of Fade Chen.

Entering from the entrance, Fade Chen first felt his feet go soft, and then a special fragrance poured into his nose and nose, which shocked Fade Chen and refreshed him all at once.

Because, this smell is exactly the smell he smelled from Mo Li before.

"This holy place can really enhance the breath of the soul, that's great."

Fade Chen was overjoyed for a moment, and hurriedly started to practice.

In this way, Fade Chen practiced in the cave, while Jiao Lin himself guarded outside the holy land.

Time goes by little by little.

A day later, Jiaolin probed into the canyon, but found no movement from Fade Chen, so he couldn't help muttering: "It's been a day, and Mr. Chen is still inside, as expected of Mr. Chen!"

Two days later, there was still no movement in the canyon, and Jiao Lin became slightly anxious: "Master Chen hasn't come out yet, so nothing will happen. After all, if you stay inside for a long time, Shenhai will be damaged!"

Three days later, it was still quiet.

Now, Jiao Lin could hardly bear it anymore, "After all, since they discovered this holy land, the longest time their mermaid clan has persisted in the holy land is only three days."

"No matter how long it takes, Shenhai will suffer irreversible damage, which will eventually cause the entrant to become insane and die violently."

"A strong man of the mermaid clan once died suddenly because of this, thus leaving this lesson for the entire mermaid clan."

Four days later, the canyon was as usual.

Jiao Lin at the entrance really couldn't sit still anymore, couldn't help but entered the canyon, came to the entrance of the cave, and wanted to call Chen Fei out. But when he took a closer look, he found that Fade Chen inside the cave was safe and sound, and he didn't seem to be in trouble at all.

So, Jiao Lin retreated.

Five days later, everything was as usual, and Jiao Lin went to see Fade Chen several times, worried that there was something wrong with him. As a result, Fade Chen was still the same as usual, it seemed that there was no difference.

Six days later, Jiao Lin who was waiting outside was numb. He could no longer imagine what kind of person was able to stay in that holy place for six full days without any discomfort.

After all, three days is already the limit of the mermaid family. The original Jiaolin himself only lasted for a day and a half, and he couldn't bear it anymore.

"Is it really okay?"

"If Mr. Chen really has a problem and I didn't remind him, what should we do?"

...

Just when Jiaolin was struggling, Fade Chen opened his eyes in the cave at this moment.

After these six days of practice, Fade Chen felt that his spirit had strengthened a lot, and even the sea of ​​spirits had grown slightly bigger. Fade Chen wanted to continue, but then he realized that he had reached the limit, and if he continued, it would not have much effect.

Therefore, he took the initiative to end his practice.

However, Fade Chen didn't leave directly, but took a look in the cave.

After observing in such a circle, Fade Chen really found something unusual.

Around this cave, there are circles of traces, neatly arranged, extending to both sides, getting smaller and smaller, very regular.

Moreover, the soft ground under his feet does not look like gravel ground at all.

Concentrating his strength, Fade Chen stabbed at the ground and dug out a piece of ground. When he took a closer look, Fade Chen was really shocked.

Because, what he dug out was not the ground at all, but a piece of meat, a piece of meat that had been placed for a long time and fused with seawater minerals.

"This—" Chen Fei's heart skipped a beat, and he looked around the cave. Close to the circle of marks, gently scrape away, and observe carefully.

Then, Fade Chen couldn't help but widen his eyes, and said in surprise, "These are bones."

"This whole cave is not a stone cave at all, but a huge animal body."

"This huge animal died here. The flesh gradually fell off and disintegrated, and the bones on the body slowly merged with the surrounding environment. The circles of marks are the rows of ribs of the animal."

Thinking of this, Fade Chen came out of the cave and cleaned up the stones, corals and other debris around the cave.

Then, swim to the top and look down at the high command.

Now, the shape of the cave below is very obvious. It is not a stone cave at all, but a huge animal corpse, which should look like a blue whale or something.

"It seems that this so-called holy place should be transformed after the death of this blue whale."

Fade Chen landed and whispered to himself, but then thought of something else.

"However, for a normal blue whale, no matter how high its cultivation base is, it has never been heard that it has the effect of strengthening the soul? Could it be that there are other reasons?"

Thinking of this, Fade Chen entered the cave again and explored it carefully.

Finally, at the end of the cave, Fade dug through the earth and found half of a skull-like remains.

In this half of the skull, there is a small circular hole with a thin blue line extending from the center of the bone.

Fade Chen dug up a piece of bone, approached it, and suddenly found that there was a strong fragrance inside, which was several times stronger than what he felt when he entered the cave just now.

Fade Chen tried other places, and found that the blue thread was in the bones, and they all had a fragrance.

And the starting point of these blue lines is the small round hole in the skull.

Seeing this, Fade Chen had a rough guess in his mind.

This mermaid sanctuary should have been a huge blue whale sea beast at the beginning.

For unknown reasons, this sea beast either mutated itself, or swallowed some treasure, and finally formed a small ball in its head.

This small ball has the effect of strengthening the soul, from the head of the sea beast, along the bones, to spread throughout the whole body of the sea beast step by step.

In the end, the sea beast died here, and the ball in its head disappeared.

But the remnants of the sea beast's body remained here and merged with the surrounding environment to form such a cave. It was finally discovered by the mermaid clan and became their holy place.

"It's just the remaining body. After so many years, it still has such an effect. Then, how effective is the little ball in the sea beast's body!" Fade Chen couldn't help but sigh with emotion.

Afterwards, Fade Chen came out of the canyon.

Seeing this, the anxious Jiao Lin hurried up to greet him, looked around for a while, and was relieved to see that Fade Chen was fine.

Chen Fei didn't hide his secrets, and told Jiao Lin about his discoveries and conjectures.

Afterwards, he bid farewell to Jiaolin and returned to Baiyue Island.
