The water hole is like a huge drum washing machine, the rapidly rotating flowing water makes people spin, and it is impossible to distinguish between the south, south, north, west, up and down, left and right, and can only be swept to the bottom with the current.

Gradually, the whirlwind subsided, and the four of them were able to poke their heads out of the water and inhale heavily.

"Are you all there?" Wang Yu looked left and right, he couldn't see his five fingers around him, he couldn't see anything, he could only hear a wheezing sound.

"I'm here." Ning Xue's voice came from all around.

"I'm here too." Then came the voice of the fat brother.

"Where is this?" Liu Zihang finally spoke.

Because everyone's flashlights had fallen into the turbulence at the bottom of the water, there was no lighting equipment in the 500-meter-deep cave world, so it was naturally pitch black.

Wang Yu offered a samadhi true fire in the palm of his hand.

The firelight shone through the embarrassed faces of the four people in the water.

Then, one by one, the darkness lit up one by one.

Only then did they find themselves in a huge underground palace.

Wang Yu had no intention of inserting willows into yin, he originally just wanted to use the Samadhi True Fire to temporarily illuminate it, but after sensing the temperature and light, the braziers around this underground palace automatically ignited one by one.

The underground palace is vaulted in a semicircle and is about the size of half a football field.

At the top of the round arch is the pattern of the river map, and in the center of the palace below is the Luo Shu pattern.

There are four elephants and beasts painted in all directions, and there are already eight stars in all directions, and there are countless auspicious rays.

There were four circular pools around the palace, and Wang Yu and the others were in one of them at this time.

"Wow! It's spectacular! The fat brother couldn't help but exclaim excitedly, his archaeological soul was burning uncontrollably.

"I didn't expect that in this bottomless pit, there would be such a glorious and magnificent underground palace." Wang Yu was also shocked.

"Could this be an ancient tomb?" Ning Xue asked.

"Probably not." Fat Brother said: "The architecture of this underground palace does not follow the tomb feng shui at all, and many of these totemic buildings should not appear in the tomb at all. So I concluded that this was certainly not an ancient tomb. ”

Wang Yu agrees with the fat brother's point of view in his heart, judging from the layout of the palace and various totems, it seems to be a place for cultivating Taoism.

Liu Zihang was more than surprised by this underground palace, but not curious, compared to him, he was more interested in the huge crocodile just now: "Do you think that crocodile will chase here?" ”

Ning Xue said: "Don't worry, the entrance to the water cave is so narrow, it will definitely not be able to enter." ”

Liu Zihang asked excitedly: "Officer Ning, I heard from you just now that the crocodile was a creature from the prehistoric Cretaceous period, is it true that it fed on dinosaurs?" ”

Ning Xue nodded and reintroduced: "Its scientific name is Pruss crocodile, it is almost invincible in the water, and it often ambushes in the water to sneak attack the dinosaurs that come to the river, even if it is a carnivorous dinosaur like Tyrannosaurus rex, once it is dragged into the water, there is only one way to die." This prehistoric crocodile is generally more than 10 meters long, more than 2 meters wide, and can weigh more than 5 tons. ”

The fat brother said admiringly: "I didn't expect Officer Ning to also have research on prehistoric creatures. ”

Ning Xue smiled: "I just happened to watch the relevant science documentary. ”

Liu Zihang was puzzled: "It is obviously a crocodile that became extinct tens of thousands of years ago, why does it appear in this deep underground cave?" ”

Wang Yu said: "The world is so big, there are no surprises. Even if there were prehistoric creatures underground, it would not be unusual. But what I can't figure out is, how did such a huge crocodile survive at the bottom of this cave? What does it eat to survive? As for those small fish and shrimp in the dark river outside, I'm afraid I can't feed it. ”

The fat brother said: "Brother Yu, you are underestimating the energy density of the red cold fish." The red cold fish is a magical fish, and the energy that a small one can provide is comparable to that of a small domestic pig. That's why they emit light, because of their extreme energy density. ”

"I see." Wang Yu understood now, and then said: "Let's go, let's go and see if there is any other exit." ”

The four of them walked from the edge of the pool to the center.

"Uncle Cousin, look!" Liu Zihang suddenly pointed to the Luo Shutai in the center of the palace in surprise.

On the stone platform sat a dried corpse, black like a strip of beef that had been completely dehydrated.

Its right hand also has an orchid finger, and the whole person looks like a god.

In front of the corpse, there was also a slender black sword.

"Is he the master of this palace?" Ning Xue asked.

"How could anyone live in this place? Isn't it a lack of heart? Liu Zihang said.

"Let's go over and have a look." Wang Yu felt that the other party should be the body left behind by a monk after his death.

Its right hand, which is the orchid method, is a typical cultivation posture.

As soon as the four of them approached the steps of the stone platform, the black sword in front of the corpse began to tremble.

"Everybody back off!" Wang Yu, who noticed the abnormality, immediately pulled out the Sword of Victory and Evil.

The black sword rose from the ground, hanging high in the sky, and then the sword body pointed at Wang Yu and stabbed down quickly.

Wang Yu felt the ferocious and cruel sword intent in this sword.

He knocked the black sword back with a backhand.

After the black sword detoured, he attacked Wang Yu again.

In the palace, the sword blades are intertwined, the sword qi is vertical and horizontal, and the walls and buildings continue to collapse.

Wang Yu felt incredible, because he felt that the sword move of the black sword actually had the meaning of Maoshan Zhuxian swordsmanship, but it was extremely violent.

This black sword became more and more courageous, making Wang Yu miserable.

The three of them were also anxious when they looked at it.

Liu Zihang scolded: "It's really hateful, which turtle grandson is controlling that sword!" ”

A flash of inspiration flashed in Ning Xue's mind, and then at the risk of being cut by the sword qi, she ran towards the center.

"Officer Ning, danger!"

Seeing this, Liu Zihang and the fat brother immediately chased after them.

Ning Xue climbed onto the stone platform with Luo Shu painted on it and pushed down the dry corpse sitting in the center.

At this time, the power of the black sword in the air also weakened a little.

Liu Zihang and the fat brother understood it, and immediately helped Ning Xue push the dried corpse off the stone platform together.

The fat brother planned to set the dried corpse on fire, but after looking for a long time, he didn't find the lighter.

Liu Zihang said while untying his trousers: "Child's urine is to ward off evil spirits, and it must be useful." ”

"Really? Then I'll do it too. The fat brother immediately acted.

Ning Xue immediately turned her head to the side.

As soon as the two of them soaked in urine, the dried corpse actually emitted thick white smoke.

The black sword also died down at this time, crumbling in the air.

Wang Yu slashed the black sword into two pieces with a single sword.

The two heroes walked back with their pants on.

Liu Zihang asked, "Uncle Cousin, what's going on with this dried corpse?" ”

Wang Yu glanced at the smelly dried corpse on the ground and said, "He should be a cultivator in front of him, who accidentally went mad and died while practicing, so there is such a big ferocity in that sword." ”

Liu Zihang's eyes suddenly lit up, and he said excitedly: "Speaking of which, isn't this place a peerless cheat?" ”

Wang Yu didn't expect this, I have to say that Zihang, this kid, is well versed in the routines of film and television dramas.

This is obvious, since this cultivator went mad and died in the practice of the exercises, there must be a secret book of this exercise nearby.

And the exercises that can make people go crazy are definitely not ordinary.

At this time, the fat brother found the mechanism in the place where the dry corpse was sitting before, so he shouted: "Brother Yu, come and see." ”

Wang Yu and the other three immediately gathered up.

The fat brother said, "You see, this is where the dry corpse sat before, and there is an echo down here, and it is empty, and there should be a switch to turn it on." ”

"Let me come!"

Wang Yu has the victory and evil in his hands, where do you need to go to the trouble to find the switch.

He pressed the blade of his sword against the stone, slashed down, and the base instantly cracked, and a sunken dark grid appeared in front of him.

"There's really a book in there!" Liu Zihang shouted excitedly.

Wang Yu took out the ancient book of green skin, opened the title page, and the four big characters came into view-Zhuxian Sword Technique!

With excitement, Wang Yu continued to read down.

All things are back to basics!!

Billion Fire Nirvana!!

Trillion Eternal Doom!!

Kyogoku Po !!

This is the lower four styles of the Immortal Sword Technique!

The upper part of the Zhuxian Sword Technique is one hundred thousand, and the lower part is one trillion trillion Zhaojing.

Wang Yu didn't expect that the lower sword spectrum that Maoshan had lost hundreds of years ago would be hidden here!

No wonder he just felt that the sword moves of the black sword had a bit of the flavor of the sword technique of the immortals.

It seems that the cultivator was forced to practice the lower part without the upper sword spectrum, so he went mad and died.
