Several of them are extremely intelligent people, and Chunyang has already understood what he means when he says this.

Indeed, such heavy lake water will inevitably press open the soft crust and sink into the ground, until it encounters a hard rock that can withstand the weight of the lake's water, and then it will stop sinking and converge into an underground lake, hidden underground, unknown to the public.

The fruit wine Taoist was also awakened by Chunyang's words, and after thinking for a while, he said: "If it is an underground lake, I know one. To the west of the city was a great river 100 meters wide, and it flowed into a crack in a mountain peak in the southwest, and it did not flow out. When I first heard about it, I went to investigate, and the crack was the mouth of a cave, and there was a lake in the wide, and the river flowed into it. However, the water of the lake is all ordinary water, and it is also poor in spiritual energy, just an ordinary place. ”

Chunyang nodded and said, "Even if it's an ordinary lake, we should check it out, after all, it's the closest place to guess, and we can't dig holes everywhere." ”

The dividing line of the legendary **** -

Outside the west city of the ancient city of Pingyang, there is a small plain, and at the end of the line of sight, there are faintly black mountain shadows.

On a huge wine gourd, the fruit wine Taoist imperial vessel took the four people of Chunyang, and in an instant, they arrived at the river he said. The river was extremely ordinary, formed by the streams in the mountains to the north, and instead of flowing into the Tongtian River hundreds of miles away, it disappeared into it when it passed through a group of mountains.

The river water is clear, there are countless swimming fish, shrimp and crabs are rampant, and a faint water spirit is nourishing the creatures in the river. The gourd fell, shrunk to its usual size, hung on the waist of the fruit wine, and picked up a handful of river water, so sweet!

Pure Yang threw out a green leaf, floated down the river, turned into a boat, and several people boarded the boat and sailed down the river.

And at a height of thousands of feet, a flying boat spans the sky, the shape of the boat is like a dragon, the dragon's head is hideous and solid, the body is huge and the golden scales are dense, the dragon's tail is swaying, and when it shakes, it is thousands of miles of mountains and rivers! Although this boat is so huge, it is silent in its actions, the wind and clouds are unmoved, and the ground looks up and does not cover the blue sky, it is actually a flying boat that can be invisible! On the dragon's head, an old man in a gray servant costume squinted at the five people floating on the river with a pair of cloudy eyes, and he did not notice it at all with fruit wine.

Between the white emperor and the clouds, thousands of miles of Jiangling will be returned in one day. Although the river is small, the flow is not slow, and the leaf boat, but in an hour, it will enter a crack in a mountain. Chunyang held up a pearl in his hand, and after entering the dark space behind the crack, the pearl bloomed with immeasurable light, and the bright sunlight illuminated the empty cave in the mountain, which was just a pearl of sunlight.

The mountain does not look high, but the space inside is large, under the illumination of the sunshine beads, the stone stalactites in the cave reflect the brilliant colorful light, adding countless wonderful scenes. As the river enters the cave, it slows down and drifts slowly.

Outside the cave, a dragon boat with a length of feet floats on the surface of the water, look at the appearance, it is actually the sky of the flying boat shrunken and transformed, look carefully, above the dragon's head, the old man in gray is still there, just the size of a finger! It is really unusual for a Taoist weapon to appear outside this small Pingyang City!

The five of them drifted with the boat for about 100 miles, all the way straight ahead, with few bends, and kept going down, and several people estimated that they were still thousands of meters deep underground at this time, and had long left the range of the mountains.

After walking another 100 meters, a vast underground lake suddenly opened up in front of everyone. The top of the cave is more than 30 zhang high, and dozens of stone pillars several zhang thick hang down, which plunge straight into the bottom of the lake and support the top of the cave; the water of the lake is cold, and from time to time a few flat strange fish with no eyes and no scales swim past the boat; under the illumination of the sun's beads, the bottom of the lake is black and swarthy, swallowing up the light, and only one zhang of water depth can be seen.

The boat circled around the underground lake, and there was no exit, and it seemed that this place was the end.

"Are we in the wrong place?" Bi Xiao said suspiciously: "There is no exit here, and I can't sense the place where there are abnormal fluctuations in the aura? Bixiao pouted, she couldn't find Magu's cave, she was more anxious than the eldest sister.

Instead, Chunyang smiled faintly and said, "The aura here is thin, and there is no abnormality but the biggest abnormality!"

"When I was outside, there was still a faint water spirit in this water, and when I entered this place, the water spirit was gone, isn't this an anomaly? Moreover, although the river water is not abundant, the amount of water is not small, and it flows here, but the water surface here does not rise in the slightest, and there must be a place where water flows out!"

"Look at me," the fruit wine Taoist strong divine thought came out majestically, sweeping towards the bottom of the lake, the divine thought was invisible, but the fruit wine's divine thought was too strong, and there were bursts of ripples on the water surface.

After a while, the fruit wine withdrew his divine thoughts, and his face was a little pale, which was caused by urging his divine thoughts with all his might. Shaking his head, the fruit wine said: "It's too deep here, after my divine thoughts are like water, I am subjected to a resistance, the further down, the greater the resistance, but only a thousand meters, my divine thoughts can't advance a bit." Senior Brother Donghua is right, this place is really extraordinary!"

After hearing this, Chunyang took out a wisp of divine sense and probed into the water, and sure enough, he couldn't go down a single inch if he went deep into Wuzhang. Fruit Wine glanced at Chun Yang in some surprise and didn't speak, Chun Yang knew that it was strange that he could turn his thoughts into divine consciousness, but he didn't explain, this is not the time to say this.

A few people can't help it, if they rush into the water, but it's not a good strategy, who knows if there are any water beasts and monsters in the water.

At this time, Yunxiao turned his gaze to the stone pillars that supported the roof of the cave, and said, "Look at these stone pillars, this underground lake is only a thousand meters wide, in such a deep underground, where do you need so many stone pillars to support? ”

"Okay, senior sister. Pure Yang urged the boats to circle along the stone pillars one by one.

Yunxiao took out a piece of paper, drew the position of each stone pillar, and counted it carefully, exactly thirty-six. At a glance, a few people understood that everything has a number of ways, nothing more than a formation. There are thirty-six stone pillars, which are the number of Tiangang, and no one believes that there is no formation prohibition.

Among several people, Chun Yang has just come into contact with the formation, and he hasn't figured out the principle yet, and he is a drunkard in the fruit wine Taoist, in addition to wine is a sword in his heart, Qiong Xiao loves swords, and Bixiao's character is not a person who can calm down and study the formation, and Yunxiao understands a thing or two about the formation because of the talent left over from his previous life.

With a few brushstrokes, Yunxiao connected the thirty-six stone pillars on the paper, replacing the aura running route with ink, and a formation diagram appeared in the eyes of several people.

The array is like Xuanwu, taking the northern water meaning, gathering ten thousand waters to condense the essence of Kwai water, which is a naturally formed Kwai water array! Kwai water array, gathering ten thousand waters, sacrificing the essence of Kwai water, water belongs to the superior formation, and the sects based on water often use this array to condense the essence of Kwai water in the rivers, lakes and seas. It's just that this array is naturally formed, and the effect is too poor, and it takes several years to condense a drop of sunflower water.

Yun Xiao pointed to a blank space in the north of the formation diagram and said, "This is where the center of the Kwai Water Array is, if there is anything abnormal, it should be here." With that, point a little to the surface of the lake.

Pure Yang drove the boat to the place where the clouds were pointing, and the strong divine thoughts of the fruit wine converged and went straight down within the range of three zhang, and after a while, he said: "Sure enough, under the water of thousands of meters, I noticed a trace of the essence of Kwai Shui. ”
