In the Loushan Cave Temple in the center of the maze, Yu Ye squatted on the ground, holding a skull and looking at it carefully.

Xiaoqing is like a mischievous child, burrowing in the cranial cavity of the skull, and the big head and thin tail will poke out from the eye holes and nostrils from time to time, as if he is doing some kind of game that only he understands; Red Powder Gu was like an old and serious elder, climbing to the top of the cave and hanging sentry.

From the skull alone, he couldn't tell which world this was a human being, and Yu Ye didn't know how to analyze how many years this person had been dead, so he looked at it for a while and put it down again, searching around for a secret passage.

I haven't found the spirit stone yet!

It should be on the ground, but after searching for a long time with his divine sense, he also found any secret passage, and after cleaning up the soil and stones on the ground, a "broken dagger" was revealed on the ground, which is naturally not a dagger, but a broken flying sword, which looks small, but can change the size with the master's mind, and the flying sword is not too big a skill, and it can be done in the sixth layer of the foundation building period, and the hilt of the sword is engraved with a beautiful "such as" word, I don't know if the road is a person or a sect name, and the broken blade is irregular, and it doesn't look like it's cut off but like it's broken.

The broken sword is also a good souvenir, so I threw it in my bag and continued to beat it around with a pickaxe, and finally found the mystery on the base of the statue.

The pedestal was made of a complete stone, and only a crack could be seen when the divine sense swept up, which I thought was formed when the mountain peak collapsed, but after sweeping away the dust, I saw that the crack was extending from both ends of an elongated gap, and the width and depth of the gap were exactly the same as the blade of the broken sword.

If the statue hadn't fallen, this gap would have been right on the edge of the shoe, maybe it would have been covered by something, it would be difficult to find, Yu Ye summoned Xiaoqing back, let the red powder Gu continue to guard the entrance of the cave, took out the broken sword and carefully inserted it into the gap.

It turned out that he was wrong, the broken sword was not a flying sword, but a key made into the style of a flying sword, and the blade was inserted into the gap without hindrance, Yu Ye heard a soft "click" sound, and then a "yah" shout, and fell down with the base.

It is a tunnel that slopes vertically downward.

The base was supposed to descend slowly, but the descending device was broken, and the mechanism that locked the base fell down as soon as it was opened, and he hurriedly flew into the air with Linyun Step, and when he fell, he was at the edge of the tunnel a little, and stood next to the bones again, and then there was a loud "tom" sound in the tunnel, and countless dust sprayed out from the mouth of the tunnel.

Yu Ye was blinded, and was frightened a lot, retreated outside to smoke and suppress the shock, and when he came back in, the dust had settled, and he took a flashlight to shine under the tunnel.

About ten meters, it's not too deep, the light of the flashlight can only shine on the broken base, the aura below is slightly thicker than above, and the cool air of Sen Sen is surging up, and it is naturally impossible to design such a secret basement just to hide the maze, there must be good things below.

After thinking about it clearly, he jumped directly from the hole, landed steadily on the broken base, and came to a stone room, but there was a sudden vibration under his feet, and he hurriedly stepped forward with Linyun, and sure enough, the base fell down again, and a large black hole with a diameter of about three meters appeared on the ground behind him, and a more gloomy cold air came out from inside, and after a while, the sound of "plopping and plopping" falling into the water came up.

There is a turbulent underground river below the stone room, it is estimated that the person who digs the stone room does not know the road, the ground is only exposed after the statue base is smashed, it is a little troublesome to go out of the road, originally straight up and down can directly move up to the tunnel mouth, now there is a big hole under the tunnel, you can't see the tunnel mouth, that is to say, you can't use Linyun step up.

Fortunately, Xiaoqing and Bao are both on their bodies, and only the Red Powder Gu is left on them, even if it takes a lot of effort to get out, it will not starve to death, the grass and leaves can be eaten, and there is at least no problem in surviving.

The maze is inlaid on the wall on the left-hand side, a total of eight spirit stones, the center of the array is a quail egg-sized array soul, there are three in the middle layer, and there are four in the outermost, the arrangement of the formation is very simple, and the real complexity is to calculate the interaction and influence between the spirit stones.

Yu Ye checked it, the aura in the nine spirit stones was almost exhausted, and it might become ordinary stones in another year or two, and the aura released didn't add up much, so he couldn't help but be a little disappointed, anyway, now there is a Tianlong beard futon to provide a lot of qi, so he is too lazy to dig it, which can be regarded as respect for the person who sets up the formation.

There is a stone bed on the right, and in front of it is a stone table, which is actually two stone platforms left out during excavation, but the stone table is wide and narrow, and a protrusion is left on the empty stone bed as a pillow.

On the wall behind the stone table is a picture of a snake with one head and two bodies, with its head at the top, and its straight body pointing downwards in both directions, in the shape of a "∧", like an open compass and a forked foot.

This is a "fat legacy", a creature in myths and legends, a snake with a single head and a double body, a pair of horns are drawn on the snake's head, the snake body is black and white, and the scales are painted clearly and delicately, but the body is too straight and does not look vivid.

Below the snake's tail, on the stone table, there are two small white squares that are crystal clear and round, very similar to mutton fat white jade, but much more transparent, it is the kind of white puzzle that Dongzang said, the one on the left is concave on the right, the one on the right is flat on the top and concave on the bottom, and the convex on the left and concave on the right.

The color and transparency are exactly the same, and there is no difference except for the shape, even if the collection is complete, I don't know how to put it together, and I can't even tell the front and back, this thing seems to be specially used to confuse people.

However, throwing his divine sense into it, Yu Ye almost screamed out, each piece of Bailiu puzzle will have some twisted and intertwined "thin threads", these threads are vacuum belts of aura, thinner than hair, and there will be several "threads" on each piece that extend to the edges with bulges or depressions.

If the threads on the puzzle pieces can be connected to each other, it is extremely easy to put together the Bailiu puzzle pieces, but it is very difficult to put together the puzzle without divine sense, after all, there is no pattern on it, and different combinations must be tried, and the complexity is proportional to the number of pieces.

Only with divine consciousness can you spell it out smoothly, could it be that this puzzle is specially for cultivators?

With the horror in his heart, Yu Ye picked up the two pieces and carefully put them in his pocket, these two pieces can be spliced together in many ways, but the "threads" can't be connected, they should belong to different positions.

So who "dug out" this thin line? Yu Ye thought for a while, and felt that if he condensed his divine consciousness into such a thin line and threw it into fragments, he might be able to suck away or push out the spiritual energy in the place he passed, but the skill that can control the divine consciousness to such a point is unheard of, and the invisible and ethereal thing like divine consciousness cannot be used to hurt the enemy.

An even more fatal question then arises - how long has the Bailiu puzzle existed? How many pieces have been found? If the ancient warriors found something made of this spirit stone, they had no divine sense and did not know the existence of the thin lines of the Dao, in case they absorbed the spiritual energy inside, wouldn't they destroy these thin lines and would no longer be able to splice them smoothly?

Yu Ye didn't know if these thin threads still existed after the aura was absorbed, and he didn't dare to try it easily, he only felt that if this puzzle was specially used by cultivators, then he would have to spend some effort to collect it, whether there were fragments destroyed or not, whether he could complete the Bailiu puzzle or not, at least he couldn't leave any regrets.

The regret in the heart is the great enemy of cultivation, it is a cruel shackle, and countless cultivators can only stay at a certain stage because they have some kind of regret in their hearts, and they will stop moving forward for the rest of their lives, leaving even greater regrets.

Therefore, most of the cultivators' personalities are very light, and there are very few people who are obsessed with something, can't hold the sand, and raise it casually, and can only cultivate the right results and live happily if they can afford to hold it and put it down.

There is nothing else in the stone room, the problem now is how to get out, the walls of the tunnel are smooth, it is impossible to climb up, and it may be possible to climb up the crane beak hoe as an ice axe to knock a hole and climb up, but if it fails, there is no way to borrow strength below, and Linyun Bu can't get out, so he can only fall into the big hole.

In any case, I can only give it a try, take out the important things in the backpack and put them close to my body, so that I can't find it after falling into the water, and then put Xiaoqing in the bag, and tell it that if it falls by itself, let the red powder Gu come back to the cave to look at the bag together, and go out to find something to eat when he is hungry.

Everything was ready, Yu Ye carried the bag in his left hand, held the hoe in his right hand, took three deep breaths, and moved to the tunnel with Linyun steps.

The tip of the pickaxe slammed the tunnel wall, and it was easily nailed in, and then it began to slide down - he was worried that the wall was not too hard, but too brittle, and he was plowed out of a deep ditch in an instant, and it was too late to regret it, Yu Ye could only throw it hard, threw his bag out of the tunnel mouth, and then fell down with helpless eyes.

Here's the water, at least don't worry about falling to your death.

Falling down more than 20 meters, the cold and biting groundwater instantly wrapped the whole body, the underground river is very narrow, only about two meters wide, about three meters deep, the water flow is very fast, and the undercurrent is surging, Yu Ye was constantly swept into the bottom of the water and surfaced, fortunately, with the help of true qi, holding his breath for more than 20 minutes is not a problem.

After floating in the water like rotten wood for more than ten minutes, his body suddenly flew into the air, and a large amount of adrenaline was secreted, Yu Ye couldn't help but let out an exclamation, dragging a long sound and falling down. It turned out that there was a huge underground cave here, and the turbulent underground river had turned into a fountain-like waterfall, and Yu Ye was "spit out" by the river, falling more than fifty meters like a cannonball, and planting his head and feet into the deep pool below.
