Chapter 1691: Planning, step by step

The next moment, twenty identical crickets, in the shape of a fan, rushed towards the dark black cave below, and disappeared into Chu Yan's sight instantly.
Chu Yan did not leave immediately, but turned around the black hole several times, keeping the topography changes and many details in mind.
If you are not worried about the formations and the sea eyes that affect the surroundings, Chu Yan even wants to throw thousands of insightful eyes around. By the way, analyze the formations that Tianyazong arranged here.
In particular, this formation that can isolate consciousness is really useful.
Although this idea was too strong, Chu Yan still held back. After another turn, he swam to a place about thirty miles away from the big cave and found a relatively large rock. He sat cross-legged on it and overlooked the big hole. Wait quietly.
After about two hours, this batch of pupae began to return one after another.
Chu Yan released twenty at that time, and eighteen returned this time.
The remaining two, Chu Yan waited another quarter of an hour, still did not wait to return.
Then Chu Yan can judge that there may be some accidents in the two encounters, either trapped or damaged.
"If my consciousness is not isolated by the formation method, then the two puppets will be damaged the first time I can detect it."
Chu Yan said a secretly in her heart, and then five fingers, one song, and one grab, sucked the listening stone on the eighteen magpies into her hands.
At the same time he waved his other hand.
Twenty puppets were released again this time, and flew towards the big cave puppet.
However, Chu Yan released this time instead of letting them explore at will, but divided the big cave into five large areas and twenty small areas according to the terrain changes he just observed from the outside, and then let Each of these twenty people performs their duties and explores.
When the second batch of twenty maggots went to investigate, Chu Yan was on this rock and took the pictures recorded in the listening wind stones carried by the first batch of eighteen maggots and carefully looked at them again. .
Although the light on the sea floor was dim, Chu Yan also prepared early.
The large night pearls in the Twelve National Treasures are set on the forehead, chest, back, wrists and ankles of the urn respectively.
The luminous range illuminates the surrounding three or four feet without any problem.
And the night pearl shines on its own, it won't cause the change of aura, it is simply necessary to explore the sea eye.
After watching the pictures in these listening wind stones, Chu Yan closed his eyes and meditated.
These pictures, at this time in Chu Yan's mind, began to outline and build with a three-dimensional space situation.
Soon after, Chu Yan had a general understanding of the situation between the caves.
"There is a vortex in this cave.
The vortex has an angle and there is no picture at all.
That shows that the two puppets who didn't return may well have had problems there. "
Chu Yan thought quietly.
The second batch of pupae released was late due to detailed exploration.
Three hours later, nineteen puppets returned.
Only one is missing.
The only thing missing is where Chu Yan didn't see the picture in the first batch.
"The problem is there, that killing gas should have leaked from there."
In Chu Yan's heart, he immediately had a more obvious goal.
So the third batch of puppets, this time targeting that area, was released.
The third batch of pupae was only ten.
But these ten salamanders are better than two thousand batches totaling forty salamanders.
Same as before, when waiting for the ten magpies to return, Chu Yan looked at the listening stones on the second batch of maggots aside.
After reading this, Chu Yan is already well-versed in this area, except for the place in the cave that is not seen in the vortex.
"It seems the problem is on that one."
After careful analysis in Chu Yan's heart, I felt that the biggest possibility should be similar to my previous guess.
"Below the sea, there is a secret place hidden by a large array.
This secret place has such a strong killing breath, it is either an ancient battlefield, or a powerful and powerful return to the market.
If it is an ancient battlefield, then there is no need to cover it with a large array.
Therefore, it is most likely that it is a land of great power.
That large array should have been eroded by the sea eye for years, and some corners were damaged, so the killing gas was leaked out.
Those three puppets who didn't return should have accidentally passed through the damage and entered the secret place.
I do n’t know how to break the team. After entering, I ca n’t come out naturally. "
With such an analysis, the problem that originally made people completely clueless suddenly became clear.
"Next, wait for this third batch of puppets, how many clues will be brought back."
Because of the clear purpose of the third batch of tadpoles, coupled with the fact that the required search range is not large, after half an hour, tadpoles returned one after another.
However, only five came back.
Something was lost, as early as Chu Yan expected, so he was not surprised.
What Chu Yan was more concerned about at this time was the five clues from the return, which would bring back some useful clue pictures.
Take out the listening to the wind stone, take a quick look, Chu Yan's eyes flashed a ray of light on this dim sea floor.
"Sure enough, everything is as I expected!"
Of the five puppets returned, three just recorded the disappearance of other puppets.
In one of the pictures, there even appeared a moment when the puppet disappeared, and a phantom of the picture of a pavilion suddenly appeared on the original bare cliff.
The Elders of the End of the World arranged the sea eye, so naturally there was no need to build pavilions on this sea floor.
Therefore, this pavilion must be built in that secret place.
"In the cave, there is a vortex, where the sea eye is, the source of the aura.
There are no detective formations, killing formations, or lost formations around.
I just need to go to the places where the puppets disappeared to enter the secret place. "
Chu Yan stood up and issued an instruction in his heart.
Soon after, Ji Shi's figure stopped quietly behind him.
Under the orders of Chu Yan, Ji Shi held a living sea fish in his hand and followed him, all the way into the big cave.
Because the matter is completely familiar with the topography, Chu Yan easily found the gap in the mystery.
In fact, there is no need for Chu Yan to deliberately seek.
The gap just needs to be closer to make people feel creepy.
It was as if the flames of fire and smoke, the hunting of flags, the smell of iron and blood, sprang up.
A little observation, Chu Yan was on the cliff, and found some rocks exactly the same as when a certain magpie disappeared.
Chu Yan hovered beside him without moving, and turned his eyes to Ji Shi.
Ji Shi hit the rocks all at once.
