A week later, Zhang Ning left the volute space and carefully explored the underground lake cave where it was located.

In Zhang Ning's original world, the caves were all dressed up and laughing against the door, but now he is in a natural and original natural cave - no colorful lighting effects - and ...... There's really nothing to look at, it's just a bunch of weird-shaped stalactites.

After looking around the underground lake for a week, Zhang Ning meditated again, and waited quietly while delving into the Qingxu Sect's peerless learning, which had only been updated after the advanced Jindan period.

Three days later, on the night of the fifteenth full moon.

There was no light in the cave, but Zhang Ning knew that the date would not be wrong, because the underground lake was no longer smooth as a mirror, but began to produce waves.

At first it was just a microwave, and over time, the microwave turned into a wave, followed by a big wave, a huge wave, and after a quarter of an hour, the whole lake shook while turning over the flowers, and the underground lake of several hundred square meters was like boiling porridge, and the next moment it could be pounced.

Zhang Ning's plastic fluorescent cup quickly transformed into a set of yellow and shiny armor, which was set on the key places of Zhang Ning's body with great momentum.

The lake water splashed like a torrential rain was evaporated into mist as soon as it approached Huang Yingying's light, and Zhang Ning resolutely stood in the yellow light and mist, his eyes like a torch.

The lake tumbled for a tea time, like a porridge pot turned off the fire, and the underground lake suddenly calmed down.

Immediately a small whirlpool was formed in the center of the lake, which gradually expanded, and quickly expanded half of the lake, and due to the centrifugal force of the whirlpool, the water at the edge of the lake swirled high and continued to rise.

At this time, the lake water is different from the previous stage, but is confined to the area of the lake once and no longer spills a drop.

The water level at the eye of the whirlpool in the middle of the lake drops rapidly until the white and smooth stalactites at the bottom of the lake are exposed.

This is the moment to wait!

Zhang Ning accumulated spiritual power all over his body and rushed into the wall of water, the huge amount of rotating lake water coupled with the resistance of the water itself made Zhang Ning immediately taken away several meters counterclockwise after entering.

He concentrated on the use of spiritual power, and sank to the bottom of the hundred-meter-thick rotating water wall in the torrent, and after his feet were on the ground, Zhang Ning walked steadily towards the center of the lake step by step.

After a tea time, Zhang Ning successfully crossed the wall of water and entered the calm whirlpool eye.

It is extremely quiet here, the white stalactites are very delicate, and there are four small finger-sized water droplets trembling slightly, and after more than a dozen breaths, another water bead is formed, five.

After another tea time, 18 rosaries were formed and automatically coiled into a string.

Zhang Ning, who had been waiting for a long time, used his divine sense to pull and directly put the string of bead-like transparent water beads in the center of the lake into the volute space, and the beads fell into the spiritual spring pool.

Immediately, Zhang Ning flew into the sky, hovering directly above the underground lake, and looked down to see the whirlpool of the lake fall without support......

Three days ago, under the guidance of Mickey, Zhang Ning learned that there would be a spiritual creature here, so he patiently stayed for a few more days, and sure enough, he waited for the legendary "Cave Swirl Rosary" to appear.

The conditions for the formation of this "cave swirl rosary" are extremely harsh, requiring the condensation of a large body of water in a cave due to the formation of a vortex due to natural tidal forces.

This kind of spiritual creature has the function of increasing the medicinal effect of the same alchemy, so it is priceless and marketable, and only exists in legends.

Zhang Ning flew towards the entrance of the western cave, he couldn't stay here for a long time, even if there were no monks passing by, the breath of the spirit would attract difficult demon beasts, and it would be useless to stay longer.

After a few hundred meters to the west, the entrance of the cave winds southward, and Zhang Ning continues along the connected karst caves.
