Although the sky was extremely dark and the bottom of the river was almost pitch black, Chen Luo quickly found the approximate location of the black stone group with his good memory.

He was prepared and took out a "treasure hunting talisman" and a Yuan stone from his chest.

At this moment, I was at the bottom of the river, but the talisman treated with tung oil was stuck on my palm, and the color of the runes on it did not fade away at all.

Chen Luo secretly breathed a sigh of relief and activated the yang power.

The light on the "Treasure Hunt Talisman" flashed, but it did not form the desired white light ball, which obviously failed.

After a few breaths, Chen Luo tried all the remaining "treasure hunting talismans", but unfortunately good luck did not come again, and the familiar scene did not reappear.

Chen Luo was not discouraged. After all, this black stone was not large in area. If there were really treasures here, it would be much less difficult than searching for piles of rocks everywhere in Hanoi without any clues.

He was about to stuff a few talismans in his hand back into his arms, when a whirlpool suddenly emerged from the surrounding river, causing him to stagger. Several talismans in his hand came out of his hand and were swept away by the surging river water.

Chen Luo didn't care about the useless talismans. After floating on the water and changing his breath, he continued to swim towards the black stone.

A waste talisman made several circles in the river and happened to float past the black stone group.

At this moment, the change regenerates!

A layer of dark blue light suddenly appeared on the dozen black stones, which was quite conspicuous at the bottom of the river. These dark blue lights quickly condensed together to form a dark blue light curtain of several feet in size, covering all the stones.

The talisman hit the dark blue light curtain, split silently.

Shen Luo's eyes widened and his figure stopped immediately.

The scene in front of him reminded him of the magic circle set up by Yu Yan and other immortal masters in the dream when they worked together to fight against the wolf king.

Of course, compared with the Liuhe Fire Array formed by Yu Yan and others, the dark blue light curtain in front of you is incomparable to the same level, neither the range nor the power nor the momentum.

He stared at the faint blue light curtain in front of him, and after a slight contemplation, he possessed himself and dug out a stone as big as a bowl from the bottom of the river, and waved his hand and threw it over.

The stones slowly drew an arc in the river water and smashed on the dark blue light curtain.

With a "bang", the stone just touched the light curtain and immediately shattered, turning into a small piece of gravel, and bursting towards the surroundings.

Chen Luo saw this scene and felt cold in his heart. He possessed himself and picked up a stone the size of a human head from the bottom of the river, and threw it over hard.

This much larger stone hit the dark blue light curtain and burst again, looking extremely fragile, while the dark blue light curtain did not move at all, and did not flash even.

He did not try again, and swam towards the river. After floating out of the water, he took a few breaths and quickly calmed down.

The river was pouring down, and the raindrops as big as beans kept hitting his face, which was quite painful. Fortunately, the flow rate of the river had not changed much for the time being.

Sink for a while and dive back to the bottom of the river again.

But the dark blue light curtain on the black stone group disappeared at some point.

Everything just now was like a dream.

Although Chen Luo felt very strange in his heart, he recalled the power of the dark blue light curtain, and did not approach him rashly.

He thought for a moment, possessed himself and picked up a stone from the bottom of the river, and threw it over with all his might.

As soon as the stones fell above the group of stones, a faint blue light flashed on more than a dozen black stones, and more than a dozen lights flew out, instantly condensed into the dark blue light curtain again.

The stones smashed on the light curtain and shattered silently again.

Chen Luo's heart skipped a beat and he was scared.

The faint blue light curtain disappeared, and it seemed that it was just a hidden track. As long as there is external interference, it will appear immediately.

After a little while he was in a slump, the man stepped back for a while again, staring at the dark blue light curtain.

Someone set up a formation in this black stone group, and there must be something strange inside. Perhaps the nameless heavenly book could be hidden here.

As soon as he thought of this, he took out a small thunder talisman and a Yuan stone from his arms.

This dark blue light curtain seems to be unable to be cracked by ordinary means. Now he only has the method of the small thunder talisman, which may be effective.

The sinking operation reduces the Yang power and activates the small thunder talisman.

The little thunder talisman cracked with a "sweep", and a white lightning flash emerged.

Shen Luo's body was instantly paralyzed, his hands and feet were trembling involuntarily, and his whole body felt as if he was pierced by countless small needles, which was extremely painful.

"Oh no, I forgot that the power of lightning can be transmitted in the water..."

His consciousness is still there, and he is very upset in his heart.

However, the pain of sinking was not too long. After the white lightning appeared, it immediately shot out forward, and the pain of sinking the body was immediately reduced.

The white lightning instantly crossed a distance of seven or eight feet and hit the dark blue light curtain, like a white snake, drilling into it.

The dark blue light curtain immediately trembled violently and flashed wildly. Moreover, the originally not thick light curtain became thin at a speed visible to the naked eye, and it was about to completely collapse.

But at this moment, the white lightning first exhausted its power and disappeared without a trace.

Shen Luo narrowed his eyes, reached into his arms with a trembling hand, took out the second small thunder talisman, and immediately used his skills to activate it.

The little thunder talisman shattered, and another white lightning flash appeared out of thin air.

Chen Luo's body became numb again, and his hands and feet began to tremble violently again, but he ignored these things and looked straight at him with his eyes fixed on his way.

Lightning flew out and hit the dark blue light curtain again.

The already thin blue light curtain was hit by a white lightning again, and immediately trembled violently again, quickly becoming thinner. Finally, with a "bang", it turned into countless blue lights and drifted away.

But at this moment, a faint white light appeared on the middle of the dozen black stones, just the black stone at the nose of the skeleton pattern, but it disappeared immediately.

Although the white light appeared for a very short time, it did not escape the falling eyes.

Chen Luo did not approach him rashly, and picked up a stone from the bottom of the river again and threw it over.

The stone did not break this time, but fell on a black stone, rolled for a while, and fell to the bottom of the river.

He was happy in his eyes, floated onto the water surface and took a breath, then returned to his original place again, swam forward with confidence, and searched around the black stone that emitted white light, carefully searching inch by inch.

At this time, perhaps due to heavy rain, the river flow rate suddenly became turbulent.

Shen Luo's body was staggered and hurriedly grabbed Black Stone before he could stabilize his steps.

He felt a stern and hurriedly accelerated the investigation.

According to this trend, I was at most looking for half a stick of incense and had to go back, otherwise it would be very dangerous. However, the protection array has been destroyed by me now, and under the turbulent water flow, it is difficult to ensure that I can remain the same the next day.

Besides, the heavy rain is storm-like, whether it can stop the next day is still a matter of two things.

Soon, he touched a stone cave the size of a bowl next to a black stone.

This cave is different from the mud caves he touched before. The holes are smooth and round, obviously not formed naturally, but seem to be artificially carved.

Chen Luo was delighted and hurriedly reached in.

The inner wall of the small hole is also very smooth, showing a cylindrical shape extending towards the ground, and the cave is filled with mud and sand.

Fortunately, the mud and sand did not solidify, so his hands could fully explore. After careful touching, he found nothing, so he continued to delve his arm.

The cave was quite deep, and the sunken body was almost pressed against the bottom of the river, and then he could barely reach the bottom. His fingers suddenly touched a hard and flat thing.

He didn't hesitate too much, and immediately grabbed the thing and tried hard to pull it up.

But this thing was hidden too deeply and was covered with mud and sand, with great resistance, so there was no twitching.

At this time, the water flow speed increased a lot again, almost making him unable to stabilize his body.

"Fight!"

Chen Luo put his heart on the ground, lying his upper body on the ground, barely stretched out his hands in, grabbed the thing, and pulled it with all his strength.
Chapter completed!
