The teleportation circle in Jia Chao's imagination is to directly teleport people from one place to another.

But the "teleportation circle" under his feet just suddenly opened a black hole!

Before they even had time to exclaim, the statues of the three of them fell straight down.

"Plop!"

"Plop!"

"Goo-dong!"

Galileo's experiments on the Leaning Tower of Pisa were overturned by them, and people of different weights did not reach the bottom of the black hole at the same time in free fall.

Jia Chao was the only one who didn't do freefall, he flew down slowly with a short sword.

With a new understanding of himself, he has been able to separate the short sword in his body and use it as he pleases.

In this forbidden land, the Ten Thousand Sword Technique and the Short Sword were the only means he could use.

Since there was only one short sword, he didn't help Xingyue and Youchen.

Anyway, below the black hole, there is a deep pool, and their lives will not be in danger.

It's just that what Jia Chao didn't expect was that You Chen couldn't swim.

After some tossing, this kid actually hugged the dog-headed statue in a panic.

The dog-headed statue floated brilliantly.

Jia Chao realized at this time that he was able to carry it easily just now, not because he had great strength, but because the dog-headed statue was hollow.

After pulling Xingyue and You Chen out of the pool, Jia Chao took a look at the surrounding scene.

It seems to be a natural cave, and it is pitch black.

Except for a waterhole, there was only this large rock on which they stood.

The black hole above their heads had completely disappeared, replaced by a cave roof full of stalactites.

"Chao, what are you looking at?" Xingyue climbed Jia Chao's arm, "Can you really see things?" ”

Jia Chao patted Xingyue's hand, then took out the "ceiling lamp" picked from the chess hall and handed it to Xingyue.

Xingyue looked at this "stone" that would glow on its own, and her eyes were full of surprise.

"You just picked it up in that hole? Is it a star in the sky? ”

Jia Chao: "Hmm...... Sort of! ”

I don't know how to answer, so I just make a mistake.

"I'll take a look under the water!"

After saying this, Jia Chao jumped down.

After searching for a while, he returned to the big rock.

"No! There is no passage in the water that can be left behind! Jia Chao shook off the water on his body and looked at the two Xingyue who were trembling with their bodies.

He suddenly remembered that they were almost ordinary people at the moment, and it was easy to catch a cold when they were wet on the edge of a cold pool.

So he immediately took out two sets of animal skin clothes and handed them to the two, and asked them to change their clothes.

If you want to avoid the embarrassment of changing clothes, it's easy to just put away the "ceiling lamp".

In the dark cave, no one can see anyone.

After the two of them changed their clothes, Jia Chao stepped on the short sword and searched above the water.

This time, he really found some clues.

Underneath a few stalactites, he found some strange crystals that looked like glass prisms.

Crucially, one of the prismatic crystals also has some kind of rune-like pattern in it.

Jia Chao studied for a while, and immediately went down to the big stone and took the "ceiling lamp" from Xingyue's hand.

He tried to illuminate those prismatic crystals with a "ceiling lamp", and soon made new discoveries.

He discovered that when light is refracted between multiple prisms, it can form a blurred light and shadow on the surface of the water.

Obviously, the light from the "ceiling lamp" is too scattered to create a noticeable focusing effect.

Jia Chao was a little speechless when he saw this, because he had no means to launch lasers at all.

After returning to the big rock and pondering for a while, he finally came up with a good idea.

Because he had the habit of freezing the fish, there were still some ice cubes in his spiritual sea space at this time.

I found a relatively large block of ice and trimmed it with a short sword to get a convex lens.

After wrapping a blanket in a canopy, placing the "ceiling lamp" in the skin, and adjusting the distance between the lamp and the convex lens appropriately, a large spotlight was obtained!

It is a bit difficult for ordinary people to operate this "spotlight", but for Jia Chao, who has practiced the Ten Thousand Swords Technique to the extreme, this matter is as easy as eating and sleeping.

He didn't even need to fly above with a short sword himself, he controlled the "spotlight" directly below to complete an experiment.

It works pretty well!

After the refraction of the parallel light, the pattern cast on the surface of the water is much clearer.

In the position of the pattern covering, Jia Chao found some clues.

It turns out that under this pool, there seems to be some kind of magic circle.

After trying it many times, Jia Chao found that this magic circle could not be activated no matter what method was used.

After studying for a long time, Jia Chao finally gave up.

He returned to the big rock and began to ponder this mysterious place.

There seems to be something very buried here, maybe some kind of treasure?

Thinking of the treasure, Jia Chao suddenly remembered someone.

This person was known by Jia Chao during the autumn hunt, his name was Tu Ming, and the elemental power he possessed was a strange black light.

Black?!

Jia Chao suddenly looked up at the dog-headed statue lying on the edge of the big stone.

The black light of Tuming seems to be the same thing as the black light emitted by the dog-headed statue!

And in the memory left by Tuming, he also has a sister named Tuyin, who has the power of white light!

Perhaps, that white light is the key to activating the magic circle in the water!

Thinking of this, Jia Chao felt a little painful.

Why did the people who designed the trials make the first few levels so easy?

The ancestor of Tuming and their tribe may be the one who brought the power of black and white light out of the Wuqi Cave.

They knew there was treasure here, but they left because they couldn't get past the rest of the levels.

However, by what means did they get out of the five chess holes?

Just as he was thinking hard, Xingyue patted him.

"Ah Chao, can't we get out?"

Jia Chao comforted her and said, "Don't be afraid, you can go out!" ”

At this time, You Chen, who had been silent, also spoke:

"Brother Chao, didn't you get a domino? Can that thing help us? ”

Jia Chao shook his head, "Can't!" I tried! Only with ordinary soul power can you read the information in the dominoes! In this forbidden place, you can't read it at all! ”

After he said this, the scene became quiet for a while.

Jia Chao simply lay flat, resting his head on Xingyue's lap, and his fingers were drawing in the air.

With the movement of his fingers, the "spotlight" suspended above also kept spinning around.

Jia Chao is changing the refraction of light from multiple angles and directions.

After all, with so many prisms, there can theoretically be a variety of combinations.

What if the image cast on the surface of the water is not the right answer?

Suddenly, Jia Chao felt a flash of light in front of him.
