In fact, as soon as everyone passed through the narrow gap, they had already seen the huge karst cave here, but they were just busy discussing the art of change and the Hundred and Eight Great Laws, and they didn't care.

It is only now that they turn their attention to the cave, where the stalactites and stalagmites make the cave a sight to behold at all times, especially since the cave is filled with clear turquoise water, making it even more fantastic.

The Hundred Tempered Steels of the Demon Sword turned into a finger twist, shuttling between the stalagmites at the bottom of the cave like a water snake, and suddenly rushed up as if he was startled by something, and shouted: "Come and see, there are crystal statues here!"

When everyone heard this, they hurriedly swam to him, only to see the Demon Sword erected in the water, and there were indeed some crystal mushroom statues of a few feet high between the stalagmites at the bottom of the cave pointed by the tip of the sword, yellow, white, green, blue and purple, the colors were dark and shallow, Mr. You Guang said: "This is not a crystal statue, but a Qingming crystal statue." ”

Yu Yunluo said: "What a skillful workmanship, but how can there be such a thing in this water hole?"

Mr. You Guang said: "This may be part of the sacrifice, or perhaps the spar of this mushroom spirit sacrificial to the snake god is to be processed, and this spar statue is one of them." ”

Xu Yibing said: "Is this also what the spell on that high platform says?"

Mr. You Guang shook his head and said, "This is my guess, in fact, we should take a look at all the high platforms in the city above, and we can get more information about this mushroom spirit." ”

Mr. Cicada said: "It's already down, it's not good to go up again, not to mention so many high platforms, I don't know how long it will take to see it, since these water holes can lead to a deeper underground world, I'm afraid we will encounter this kind of thing along the way, maybe we can get some clues." ”

"What Mr. Cicada said is, let's keep walking, these spar statues will be put away first, and maybe they will come in handy later. Feng Luqi threw all these spar mushroom spirit statues into the dimensional satchel, and then swam to the statue first, and the others followed Feng Luqi.

The statue was stopped in front of a small hole seven or eight feet wide, showing the crowd the way forward. This artifact is extremely spiritual, and when people stop, it will stop and wait, but it will wait in the direction of progress, and when people want to continue to move forward, it will guide everyone forward at the right speed.

Sensing that everyone was approaching it, the statue turned around and entered the small hole, and everyone followed in, only to see that there was a narrow cave waterway inside, with dense stalactites like sharp cones on top, and stalagmites standing below, and the gap in the middle was only three or four feet high, and everyone could no longer move forward upright, but it was not enough to become smaller, so they all leaned forward, flattened the bubbles of the water avoidance, and continued to move forward in it.

Shi Jingua didn't use the trick of avoiding water as always, and swam faster than everyone else, and soon surpassed Feng Luqi, who came first.

This waterway is five miles long, and there are no branches, just out of the waterway, a light suddenly falls from above, Shi Jingua looked up, through the clear water above, you can see a nearly circular hole. The light that fell from above was the phosphorescent light of the mushroom jungle that fell from the mouth of this cave.

The people behind came out of the waterway, saw the light falling from above, and also looked up to see the hole above, Mr. You Guang said: "It seems that this is another holy well, there may be a city or village on it, do you want to go up and have a look?"

"Forget it, it's important to hurry up and find the artifact. Honggu harnessed the bubble to swim towards the statue, and it had stopped at the hole in the rock wall on the other side.

There were three openings at the bottom of the well, leading to three dark rivers, and if they didn't have a statue to guide them, they probably chose the wrong path.

After diving with the statue for more than an hour, everyone found a total of more than ten sinkhole holy wells connected by a dark river at the bottom, and they also felt the intricacy of the dark river network under this mushroom jungle.

In the process, they also found a lot of handicrafts of the mushroom spirit, most of which were made of Qingming spar, and they were all collected into the dimensional satchel by Feng Luqi.

At this moment, they had just come out of a waterway more than ten miles long, and it looked like they had entered the Tiankeng Holy Well again, but there was no light falling from it.

When everyone looked up, they saw that a thick cloud of fine sand seemed to float on the clear water.

Mr. You Guang felt incredible, so he invited the statue to shoot a beam of divine light to illuminate the clouds, and at the same time opened the eyes of the sky to see, only to find that it was a sulfur gas layer through microvision, and the perspective made him find that above this thick layer of sulfur gas, there was a deep layer of clear water, and further up was a sinkhole hole.

Above the sulphur cloud is a freshwater layer with a very low salt content, which is lighter than sulphur, so it can float on it. Below the clouds is a saline layer, which has a high salt content and is heavier than sulfur, so it sinks under the clouds. It can be seen that this holy well is much deeper than the sinkhole they had passed through before.

Seeing these situations, Honggu couldn't help frowning: "Is there no problem with the path that this statue has pointed us out? After so long, why is it still between the holy wells, and there is no deeper underground at all." ”

Mr. You Guang said: "Princess, don't worry, in fact, we have been advancing deeper underground, this holy well is obviously much deeper than the holy well we have passed before, I believe that the dark river connected to the bottom of this holy well will definitely lead to deeper underground, and we may not enter another holy well." ”

"I hope you can do as you say, and keep going. Honggu swam to the statue first, and the others followed.

Sensing the approaching crowds, the statue entered a hole seven or eight feet wide, and the crowd entered a dark river channel, but this channel was deep and very steep.

Honggu looked back and smiled: "It seems that you really got what you said." ”

"The city I first discovered was a small city, and the holy well it enshrined was only connected to the Dark River Network, and this holy well was the center of the Dark River Network, and it also connected the road to the deeper underground world. ”

Feng Luqi said: "Sir, you mean that there should be a big city on this holy well?"

Mr. You Guang said: "Maybe, I'm just guessing, after all, this holy well is very deep and large, and it is connected to a waterway that goes deep into the ground, unlike other holy wells, but it is connected to a network of dark rivers. ”

Yu Yunluo said: "If there is really a big city, I really want to go up and see it." ”

Su Yu said: "Let's find the artifact component first, and then talk about it, you can find the secret and explore the strange at any time." ”

The crowd followed the statue and went all the way down the waterway into the ground, diving for five miles before leaving the waterway and entering a huge karst cave filled with water.

Amazingly, at the bottom of it was a jungle of phosphorescent algae, hiding a sacred well, and the surrounding city with many high temples, and everyone was immediately attracted to it, and they dived to the underwater city.
