When the demon god thought of this, he couldn't help but be shocked in his heart.

If someone obtained the bloodline of the Three Holy Beasts, it would indeed be a disaster for the Demon Clan, and what he saw now was only the beginning.

The blazing vermilion fire rose again, and a flame-shaped figure appeared, which was Xiang Jian.

He appeared intact now, and finally brought into full play the power of the blood factor of the Three Holy Beasts.

With a move of his hand, the ink torture flew towards Xiang Jian as if he was attracted by a magnet, and when he held the sword in his hand again, the combat power belonging to the main god realm was revealed, and with a wave of the long sword, it slashed towards the head of the demon god.

"It's really interesting, just a god of the earth, but he can explode two levels in a row, and he has the strength of a heavy heaven that is not weaker than the main god realm, although I underestimate you, but in the face of absolute strength, all your efforts will be in vain. ”

The demon god said leisurely, and threw the water fairy who almost choked on the ground.

Yue Yao took the Eastern Emperor, the Eastern Emperor, Dongfang Xiuji, Huang Muran, and Huang Muyuan all the way through the clouds, and soon explored all the suspicious places, but found nothing.

Yue Yao asked: "I traveled to this land in the early years, and I remember that there was a big karst cave near here, and I explored it today, but I didn't find it, do you know?"

"Yue Daoyou, I already knew it before, but it's been a long time, but now I can't remember it, it's vaguely on the edge of a cliff in a big mountain, anyway, it's not far from the big river. Huang Muyuan replied.

"That being the case, let's explore the river, and I hope my feeling is right. ”

After Yue Yao finished speaking, he took the lead in looking for the river, and the five immortals such as Dongfang Xiuji also immediately followed.

The six immortals turned into a long time, and finally went up the river and found the high mountain cliff.

It's just that there is no portal in the cave, and someone must have deliberately hidden it.

"This cave is 150 kilometers long, no less than 400 meters deep, and has many forks, but it is also an excellent hiding place. Graphite is the reincarnation of Mai Xian, the son of the 'dead' son of the Lord of the Nine Falls, and this matter is very important and must not be noticed, otherwise there will be endless troubles. Let's be cautious and go down. ”

Yue Yao warned again, and then the immortal body flashed, and then disappeared into the cliff.

The karst cave is the underground space formed by karst in the soluble rock, and its formation is the result of long-term dissolution of groundwater in the limestone area, and the insoluble calcium carbonate in the limestone can be converted into soluble calcium bicarbonate by the action of water and carbon dioxide.

Because each part of the limestone layer contains different amounts of calcareous and different degrees of erosion, it is gradually dissolved and divided into karst caves that are not interdependent, diverse, steep and beautiful peaks and strange landscapes, and the landform formed by this is generally called karst landform.

For example, Guimu Cave, Shihua Cave, and Meilong Palace are masterpieces created due to the slow erosion of water and carbon dioxide.

When water dissolved in calcium bicarbonate drips from the top of the cave to the bottom of the cave, the solubility of carbon dioxide will decrease due to the evaporation or pressure reduction of the water, as well as the change of temperature, and the precipitation of calcium carbonate will be precipitated.

After millions of years of accumulation, these precipitations gradually formed stalactites, stalagmites, etc. as

The water dissolved in calcium bicarbonate drips from the roof of the cave, and with the volatilization of water and carbon dioxide, the precipitated calcium carbonate will accumulate into stalactites, stone mantles, and stone flowers.

When the stalactites on the roof of the cave are connected to the stalagmites on the ground, they form strange stone pillars.

In nature, rainwater dissolved with carbon dioxide partially dissolves the rock formation made of limestone, turning calcium carbonate into soluble calcium bicarbonate.

Nature has repeated the above reactions for a long time and many times, resulting in the formation of various strange and magnificent karst caves, such as Seven Star Rock, Reed Flute Rock, Zhushan Cave and so on.

In the cave, there are stalactites and stalagmites in various forms, which are formed by the decomposition of calcium bicarbonate and the deposit of calcium carbonate.

Karst refers to the landform formed by the dissolution of soluble rocks, especially carbonate rocks, by flowing water containing carbon dioxide, and sometimes by sedimentation.

It is often in a peculiar shape, with caves, stone buds, stone ditches, stone forests, karst caves, underground rivers and cliffs.

In this kind of landform area, there are often many strange peaks.

The Six Immortals continue to move in the cave.

The strange peaks and caves presented in the cave are all artificially created.

Steep rock walls, curved ravines, high ice-eroded hanging valleys, and majestic small valleys also have a natural portrayal of the erosion effect of "dripping water through stones".

The wide place in the cave is like a square, the narrow place is like a long corridor, and the high place is 30 meters, and the whole cave plane is tortuous, and it can be divided into three layers vertically.

In the rainy season, there is flowing water in the whole cave, which becomes an underground river and the river falls down at the bend of the slope to form a waterfall; in the dry season, there is water in some areas, which becomes an underground lake, and there may be a pool with deep water, which may be called a bottomless pool.

Among them, there are countless stone pillars, stalagmites, and strange caves, as well as Poli Valley and Tiansheng Bridge, and various colors plus strange milky shapes, which can be called a fairyland.

This karst cave is a large karst cave group integrating karst geological and landform landscapes such as karst caves, canyons, peak forests, cliffs, streams, funnels, dark rivers, etc., with nine layers of caves, so a stone tablet has the name of "Nine Heavens".

The six immortals came to a cave with seven "halls" connected by a narrow "corridor", and in front of the cave was a huge stalagmite, and behind the stalagmite was an unreachable sinkhole, which also had a certain scale.

The landscape in front of the cave is dazzling, and there are countless peerless wonders. The waterway is mysterious and unpredictable, you can take a boat to swing a boat, tread the water to find immortals, look up at the nine heavens, the dry road winds and paths are secluded, you can stroll and watch quietly, the peak turns around, and the stalagmites and stalactites are savored.

There are also canyons and clouds, pavilions and pavilions, palaces and fairy gardens, ancient riverbeds, and the karst cave landscape is exquisite, which is beautiful, so that the six immortals are dizzying.

After passing through the hall, you will follow the path down to the mouth of a cave called the "Little Ladder", and further to the right, the road is very difficult, and you need to climb over a very high stone ladder.

Not far from the foot of the rock is the "White Car Cave".

This cave has a double opening, the entrance in front of the door can clearly see the scene of the junction of the three places of chicken, there is a small crack on the rock wall on the cave entrance, that is, the double hole of the white car karst cave.

The cave is very narrow, and people who are not small can not enter, and the road inside is dark and lightless, and no light source can enter.

The road in the cave is rugged and there are walls everywhere.

You can't enter without climbing, there is a level that is very small, for a hurdle, climb the foot of the hurdle first.

After squirming for hundreds of breaths, you can reach the beautiful and charming cave hall, the temperature in the hall is slightly higher than the outside, and it can also make people sweat in winter.

The cave is resplendent with gold, as if you are in paradise on earth.

After passing through the hall and entering a cave, you will see the stone stalactites in the cave, and the stalagmites are dizzying. The name is "Yunshui", the depth of the hole is more than 600 meters, and it naturally forms six halls.

The first hall is more than 50 meters high, 30 meters wide, and the scenery in the hall has the scenery of Crouching Tiger Rock, Black Dragon Pond, Erlong Gate, Half Hanging Mountain, Fire Cave and so on.

The second hall has fairy carvings, salt mountains, jujube chestnut mountains, lion lotus, stone people, two dragons playing with pearls, climbing pillars and other scenery.

The most striking thing in the hall is the Climbing Pillar, which is a stalagmite with a height of 37 meters, which can be called the leader of the stalagmites.

The scenery of the third, fourth, fifth and sixth halls is also very pleasing to the eye, and the colorful and bizarre natural scenery is really rare.

A group of stone immortal statues hugging each other in front of them, scattered, with different forms, like a solemn dojo, which is incredible.

Further forward a karst cave, the width of the cave is about 50 meters, the height is about 30 meters, the giant cave can accommodate hundreds of people, and there are stoves and other things.

In the cave, the big cave is set of small holes, and stone curtains, stone flowers, and cloud basins abound.

Then move forward, another cave in the gorgeous stalactites, stalagmites, etc. immediately presented in front of you, the natural cave is composed of seven caves, such as Niu Cave, Green Wave Cave, Tianshengqiao Cave, Liang Cave, Yinpan Cave.

The caves were connected to each other, and the six immortals walked for two or three hours before they finished.

Then, a large karst cave appeared, and there were stone stalactites shaped like a large green dragon on the walls of the cave.

The karst cave is mainly formed after the long-term dissolution of groundwater in the limestone area, and after a long period of dissolution, it is gradually divided into a strange landscape that is not interdependent, varied, steep and beautiful, and is naturally called the karst cave wonder.

"It is worthy of the 'Nine Heavens', this underground cave is quite gorgeous, and the strange peaks and caves are described like this, it is really a fairyland on earth. Yue Yao exclaimed.
