Although the sky was extremely dark and the riverbed was almost pitch black at this time, Shen Luo relied on his good memory and quickly found the approximate location of the black stone group.
He was well prepared and took out a "treasure hunting talisman" and a Yuan stone directly from his chest.
At this moment, I am at the bottom of the river, but the talisman treated with tung oil is stuck on the palm of my hand, and the color of the rune on it has not faded at all.
Shen Luo secretly breathed a sigh of relief and activated the Xiao Hua Yang Gong.
The light on the "treasure hunting talisman" flashed, but it did not form the desired white light ball, obviously failing.
After a few breaths, Shen Luo tried all the remaining "treasure hunting talismans", but unfortunately his good luck did not come again and the familiar scene did not reappear.
Shen Luo was not discouraged. After all, the area of this black stone was not large. If there really was a treasure here, it would be much easier than searching the piles of rocks in the river without any clue.
He was just about to stuff the few useless talismans in his hand back into his arms when a whirlpool suddenly appeared in the river around him, causing him to stagger. The talismans in his hand flew out of his hands and were swept away by the surging river water.
Shen Luo ignored the useless talismans. After floating to the surface to take a breath, he continued to swim towards the black stone.
A useless talisman made a few circles in the river and happened to float over the black rocks.
At this moment, another mutation occurred!
Suddenly, a layer of faint blue light appeared on more than a dozen black stones, which was quite conspicuous at the bottom of the river. These faint blue lights quickly condensed together to form a faint blue light curtain several feet in size, covering all the stones.
The talisman hit the dark blue light curtain and shattered into pieces silently.
Shen Luo’s eyes widened and he stopped immediately.
The scene before him reminded him of the magic circle set up by Yu Yan and other immortal masters when they joined forces to fight against the Wolf King in his dream.
Of course, the dark blue light curtain in front of him could not be compared with the Liuhe Fire Array formed by Yu Yan and others, whether in terms of range or power and momentum.
He stared intently at the dark blue light in front of him, and after a moment of hesitation, he dug out a bowl-sized stone from the bottom of the river and threw it over.
The stone slowly drew an arc in the river and hit the dark blue light curtain.
With a "bang", the stone shattered as soon as it touched the light curtain, turning into small pieces of gravel that shot around.
When Shen Luo saw this scene, he felt a chill in his heart. He picked up a stone the size of a human head from the bottom of the river and threw it over with all his strength.
This much larger stone hit the dark blue light curtain and exploded again. It looked extremely fragile, but the dark blue light curtain did not move at all, not even a flicker.
He did not try again, but jumped towards the surface of the river. After surfacing, he took a few deep breaths and quickly calmed down.
Heavy rain was pouring down on the river. The big raindrops kept hitting his face, which was quite painful. Fortunately, the flow rate of the river did not change much for the time being.
Shen Luo took a short rest and dived back to the bottom of the river again.
But the dark blue light curtain above the black rocks had disappeared at some point.
Everything that just happened seemed like a dream.
Although Shen Luo felt very surprised, he recalled the power of the dark blue light curtain and did not approach it rashly.
