The next moment, twenty identical puppets formed a fan shape and headed towards the dark and gloomy black hole below. In the blink of an eye, they disappeared from Chu Yan's sight.

Chu Yan did not leave immediately, but walked around the black hole several times, memorizing the changes in the terrain and many details.

If he were not worried about affecting the surrounding formations and sea eyes, Chu Yan would even want to throw thousands of Insight Eyes around, and by the way, analyze the formations arranged by the Tianya Sect here.

Especially this formation that can isolate spiritual consciousness is really useful.

Although this idea was too strong, Chu Yan still resisted. After another circle, he swam to a place about thirty miles away from the big cave. He found a relatively large rock and sat cross-legged on it, overlooking the big cave.

Wait quietly.

About two hours later, these puppets began to come back one after another.

Chu Yan sent out twenty of them at that time, and this time eighteen came back.

Chu Yan waited for another quarter of an hour for the remaining two, but still did not come back.

Then Chu Yan can judge that these two puppets may have had some accident and were either trapped or damaged.

"If my consciousness was not isolated by the formation, I would have noticed the two puppets as soon as they were damaged."

Chu Yan secretly thought to himself, then he moved his five fingers and grabbed the wind-listening stones on these eighteen puppets and sucked them into his hands.

At the same time, he waved his other hand again.

This time, another twenty puppets were released and flew towards the big hole.

However, Chu Yan did not let the puppets released this time to explore at will. Instead, he divided the big hole into five large areas and twenty small areas based on the terrain changes he had just observed from the outside.

These twenty puppets each perform their duties and explore.

When the second batch of twenty puppets went to investigate, Chu Yan was on this rock and carefully read the scenes recorded in the wind-listening stones carried by the first batch of eighteen puppets.

.

Although the light at the bottom of the sea was dim, Chu Yan was also prepared early.

The large luminous pearls from the treasures of the Twelve Kingdoms are respectively inlaid on the puppet's forehead, chest, back, wrists and ankles.

The luminous range can illuminate the surrounding three to four feet without any problem.

Moreover, the luminous pearls emit light on their own and will not cause changes in aura, making them a must-have for exploring the Eye of the Sea.

After seeing these scenes in Tingfeng Stone, Chu Yan closed his eyes and meditated.

These pictures, at this time, began to be outlined and constructed in a three-dimensional space in Chu Yan's mind.

Soon after, Chu Yan had a general understanding of the situation between the big holes.

"There is a whirlpool inside this cave.

The vortex has an angle that doesn't get the picture at all.

That means the two puppets who didn’t come back probably had a problem there.”

Chu Yan thought quietly in his heart.

The second batch of puppets released came back relatively late because they were being explored in detail.

Three hours later, the nineteen puppets came back.

Only one is missing.

The only thing missing was the place where Chu Yan didn't see the picture in the first batch.

"The problem is there. That murderous aura should be leaking from there."

Chu Yan suddenly had a more obvious goal in his mind.

So the third batch of puppets was released this time targeting that area.

There are only ten puppets in the third batch.

But these ten puppets are far more sophisticated than the total of forty puppets produced in two thousand batches.

As before, while waiting for the return of these ten puppets, Chu Yan looked at all the wind-listening stones on the second batch of puppets.

After reading it, Chu Yan already knew all the other locations in this sea area, except for the place where the whirlpool in the cave was not visible.

"It seems that the problem lies in that area."

Chu Yan analyzed it carefully in his mind and felt that the most likely possibility was similar to his previous speculation.

"Below the eye of the sea, there is a secret place hidden by the formation.

This secret place has such a strong aura of killing, it is either an ancient battlefield, or the place where a powerful person with great killing intent returns to his ruins.

If it were an ancient battlefield, there would be no need to use a large formation to cover it.

Therefore, it is the most likely place for the great power to return to ruins.

That large formation must have been eroded by the Eye of the Sea for many years, and there was damage in a corner, so a trace of the murderous spirit inside was leaked out.

The three puppets who didn't come back probably accidentally entered the secret place through the damage.

The puppets don't know how to break the formation, so once they get in, they won't be able to get out."

With such an analysis, the problem that was originally completely confusing suddenly became clear.

"Next, let's wait and see how many clues this third batch of puppets will bring back."

Because the purpose of the third batch of puppets was clear, and the required search area was not large, the puppets came back one after another after more than half an hour.

But there were only five puppets who came back.

Chu Yan had expected some losses, so he was not surprised at all.

What Chu Yan is more concerned about at this time is how many useful clues the five puppets will bring back.

Taking out the wind-listening stone and browsing it quickly, a ray of light suddenly flashed in Chu Yan's eyes in the dim seabed.

"Sure enough, everything is just as I thought!"

Three of the five puppets who came back happened to record the disappearance of the other puppets.

In one of the scenes, there was even a moment when a puppet disappeared, and the shadow of a pavilion suddenly appeared on the originally bare cliff.

The elders of the Tianya Sect arranged the sea eye, so naturally there was no need to build pavilions and pavilions on the seabed.

Therefore, this pavilion must have been built in that secret realm.

"There is a whirlpool in the cave, which is where the Eye of the Sea is and the source of spiritual energy.

There are no probing formations, killing formations, or confusion formations around.

I only need to go to where those puppets disappeared to enter that secret place."

Chu Yan stood up and issued an instruction in his heart.

Not long after, Ji Shi's figure stopped quietly behind him.

Under Chu Yan's order, Ji Shi grabbed a living sea fish in each hand and followed him, diving into the big hole.

Because he was already completely familiar with the terrain, Chu Yan easily found the gap in the secret realm.

In fact, there was no need for Chu Yan to search for it deliberately.

That gap can make people feel creepy just by getting closer.

It's like the smoke of a beacon fire, the flags are flying, and the smell of iron and blood arises spontaneously.

After a brief observation, Chu Yan found several rocks on the cliff that were exactly the same as when a certain puppet disappeared.

Chu Yan hovered beside him without moving, looking at Ji Shi.
