Wang Xu, who used the soil system primary Dao technique, escaped into the damp sludge under the floor of the hall, although the earth escape technique was not a profound earth system Dao technique, however, Wang Xu usually did not use this Dao technique often, so he was still very unfamiliar with this earth system Dao technique.

Therefore, when Wang Xu escaped into the sludge, he could only slowly retreat downwards while studying this Taoist technique as much as possible.

Fortunately, after the excavation escape, Wang Xu was able to see the objects in the surrounding soil layer during the escape, which made Wang Xu a lot easier, at least he would not be like a blind man touching an elephant and struggling in the soil.

At this time, Wang Xu, who had already dived into the soil layer dozens of meters deep, suddenly found that the surrounding soil was very soft, and it was full of water, which looked like cement and did not look like ordinary soil.

Because the surrounding soil conditions were very different from Wang Xu's judgment, when Wang Xu searched the soil layer below the teleportation array for almost five minutes, he still didn't find the six godhead crystals.

Suddenly, a violent vibration of "boom ......", like water waves, started from the hall and spread out to the surrounding soil layer, at this moment, Wang Xu, who was hiding in the soil, was almost broken by the energy of the vibration, fortunately he gritted his teeth and held on, otherwise, he would have to be buried alive in the soil.

Feeling the powerful energy around him that could tear through the strata, Wang Xu understood that the hundred or so Extreme Explosion Talismans he had scattered in the hall had exploded, and those arrogant spiders had already become minced meat.

Suppressing his curiosity to go over and see what was going on, Wang Xu continued to wander through the soil, looking for the six godhead crystals.

After eating four or five Qi Replenishing Pills in a row, Wang Xu had been wandering around in the soil layer for half an hour, but he still didn't see the six Godhead crystals, at this time, he muttered in his heart, could it be that those six Godhead crystals had been taken away?

After thinking for two or three minutes, Wang Xu thought of a possibility, he felt that because the surrounding soil contained a lot of water, and the six godhead crystals had been buried under the soil for thousands of years, so, at this moment, the six godhead crystals were likely to have sunk deep into the ground.

Now that he had a clear judgment, Wang Xu fled to the depths of the earth, and after passing through two layers of groundwater, Wang Xu escaped into a large karst cave.

Wang Xu, who was standing on a stone island the size of a round table in the middle of the cave, looked around after releasing several glowing mahogany swords to illuminate the pitch-black space around him.

He saw that this circular cave was about the size of a football field, almost six stories high, and the bottom of the cave was full of water, and under the clear water, it was so black that he couldn't see the bottom at all, and he couldn't see any moving creatures, but he saw several black holes on the cave wall below the water, and those holes were only as thick as a calf, which looked like they should be the channels of the underground rivers.

On the top of the cave, there are stalactites of different lengths and thicknesses hanging upside down, those stalactites are constantly dripping downward, countless water droplets, on the water surface of the deep pool at the bottom of the cave, rippling out a circle of intertwined ripples.

Wang Xu also saw that there were a lot of stalactites on the top of the cave, so many that the roof of the cave was densely covered, and what was even more amazing was that the stalactites were all different in color, including white, black, red, and even gold.

After seeing the wonders of the top of the cave, Wang Xu looked down at the deep pool under his feet, and he found that in this black and oily pool, there were five small stone islands standing abruptly, in addition to the one under his feet, there were four.

Suddenly, Wang Xu saw that on one of the small stone islands not far from him, there were a lot of things piled up, due to the lack of light from the glowing mahogany sword, Wang Xu couldn't see what the pile was, and he could probably see some metal objects similar to armor and helmets.

Just when Wang Xu stepped on the flying sword and was about to fly to the small stone island full of things, suddenly, with a "pop!", a water column with a height of one person and a thigh thick appeared on the surface of the water, and the water column seemed to have life, and shot towards Wang Xu who was flying in mid-air.

As soon as Wang Xu saw the water column coming, he immediately kicked the flying sword hard, and then, using the reaction force, Wang Xu rushed forward and rushed to the small stone island, and then, Wang Xu turned to look at the water column.

I saw that after the water column hit the flying sword, it quickly cooled, and in an instant, it condensed into an icicle, freezing the flying sword inside.

Seeing the miserable appearance of his flying sword, Wang Xu's back instantly had a layer of cold sweat, he took a deep breath, wiped the sweat on his forehead, and muttered in his heart: Fortunately, I reacted quickly, otherwise, it would be me who was frozen.

Without giving Wang Xu any time to rest, with a "poof!", a black tentacle thicker than a telephone pole emerged from the water, and this tentacle instantly hit the flying sword in the icicle, and in the next second, the icicle and the steel flying sword shattered into a sky of ice mist together.

"I'll go!" Wang Xu scolded secretly, his heart was full of shadows, and his heart said, fortunately, the tentacle didn't sweep towards me, otherwise, at least I would have to break a few ribs.

Just when Wang Xu was secretly glad that he was not miserable enough, suddenly, with a few roars of "Teng, Teng, Teng ......", countless black tentacles rushed out of the deep pool, with a mist in the sky, covering the sky and the sun, sweeping towards Wang Xu.

Between the lightning and flint, Wang Xu first dodged a black tentacle that swept over his head, and then, turning over and raising his hand, he pasted an extreme explosive talisman on the black tentacle above his head, and then, with a hard kick, flashed a black tentacle pressed from the top of his head, and then, with a flick of his hand, on this black tentacle, an extremely explosive talisman was also pasted.

Immediately afterwards, after Wang Xu bowed down and dodged a black tentacle that stabbed him in the waist, he quickly sacrificed a peachwood sword, which instantly made the peachwood sword bigger, blocking his back, blocking five black tentacles that swept from behind at the same time.

Hearing a chaotic sound of "bang, bang, bang......", when the peachwood sword was stirred into a piece of sawdust by the five black tentacles, Wang Xu had already picked up a new flying sword and flew to another small stone island.

"Boom, boom!" Two loud sounds, accompanied by the fire in the sky, the countless stalactites on the top of the cave, and the two black tentacles that were pasted with the extreme explosion charm by Wang Xu, were blown to pieces by the extreme explosion charm, and the colorful stone chips accompanied by the dirty blood in the sky fell on the water surface of the deep pool.

In the next second, the pool began to surge, and countless huge bubbles emerged from the pool around the small stone island where Wang Xu was standing just now, and then, a black object that seemed to be higher than the cave came out of the pool water, with a full water mist and a huge roar, and fell on the small stone island with a "bang".

Wang Xu turned around quickly, and at a fixed glance, he finally saw who was plotting against him, only to see that on the small stone island opposite, a three-story black octopus was wriggling.

This octopus originally had eight black tentacles full of white suckers, but two of them had just been blown off by Wang Xu, and only six were still wriggling.

On the broken surface of the two tentacles that were blown off by the black octopus, black blood kept bubbling outward, and gradually, the dirty blood stained the entire deep pool into a deep black.

"Who are you?" the black octopus actually spoke, still speaking the continental lingua franca.

"Who are you?" Wang Xu asked the black octopus rhetorically, he didn't plan to grind with the octopus opposite, he planned to kill it quickly, because Wang Xu had already seen the six godhead crystals he dreamed of, and the six godhead crystals were inlaid by a black octopus on a golden crown, and the crown was inlaid on his head by the black octopus.

At this moment, Wang Xu did not observe any weaknesses of the octopus, because the octopus is not only fast, but also has strong attack power, in addition, its attack range is not small, and it is a local snake that is familiar with the terrain here, so Wang Xu feels that it is still very difficult to deal with it on its territory.

"Whew!", the black octopus was enraged by Wang Xu's answer, and it stretched out its six tentacles to the top of the cave, and the six tentacles grabbed the six sharp stalactites on the top of the cave, and then, towards Wang Xu, the black octopus threw out the six stalactites at the same time like throwing darts.

At that moment, Wang Xu found that the black octopus was still quite smart, it knew that its extreme explosive charm was very powerful, and it could easily blow up its tentacles, so it no longer used its tentacles to attack itself, but used the countless stalactites on the top of the cave to carry out long-range attacks.

"Ding!", Wang Xu waved his sword to cut off a stalactite that flew towards him, dodged the remaining five stalactites, felt the sharp pain from his wrist, he said in his heart, it seems that I can't fight with it, its strength is indeed above me, I can only take advantage of its weakness and kill it.

After dodging another round of black octopus dart attacks, Wang Xu released a fireball spell towards the black octopus's head, only to see a small fireball the size of a fist shining bright red light, flying towards the black octopus at a rapid pace.

When the black octopus saw the small fireball flying towards it, it didn't panic, stretched out a tentacle, and slapped it on the water in front of it, and saw that an icicle instantly appeared on the water, blocking the path of the small fireball flying towards it.

"Whew!", a small fireball hit the icicle, and the icicle was blown into a piece of Xiaoice, and the Xiaoice piece was instantly evaporated into a flood of water vapor under the residual heat of the fireball.

Taking advantage of the opportunity of water vapor to block the black octopus's vision, Wang Xu stepped on the flying sword and flew towards the octopus quickly, just as he was about to throw an extremely explosive talisman on the top of the black octopus's head, with a "whoosh" sound, a black tentacle swept horizontally from the mist, and this tentacle was like a steel whip, when the chest was drawn on the breastplate on Wang Xu's chest.

"Dang!" with a loud bang, first Wang Xu's breastplate was dented, and then, Wang Xu himself flew out upside down like a cannonball, and then, with a "bang!", hit the wall of the cave, and finally, with a "poof", fell into the deep pool......

Seeing the black octopus after Wang Xu fell into the deep pool, he quickly got into the pool and swam quickly to Wang Xu's location, ready to enjoy a beautiful meal......
