Hearing the tragic wail coming from the cave behind him, the four Cangyun disciples who hadn't gone far all changed their faces drastically, and they didn't dare to turn their heads, and hurriedly rushed to the depths of the passage.

Bai Yi had already walked far away, and he still heard the screams, and his feet couldn't help but be a little faster.

"A thousand insectivores, troublesome things. ”

In a whisper, Bai Yi walked through a small karst cave and into a relatively spacious passage.

The jade pendant on his waist moved slightly, and Yan Shan's question came: "Do you recognize the insect demon of the underground world?"

"The fourth-level insect demon, comparable to a Jindan monk, moves slowly, eats everything, and has seen it in books. Bai Yi said casually.

"The old man has cultivated for thousands of years, and he has also entered the depths of the earth, and he has seen some underground insect demons, but he has never seen such a big strange insect, and you have read a lot of books. ”

Yan Shan seemed to be praising it, but his tone was obviously not convinced, how old Bai Yi was, if the strange things in the cultivation realm were compiled into a book, the monks might not be able to read them for decades, let alone a sixteen or seventeen-year-old boy who had just entered the cultivation realm.

Bai Yi's face was a little gloomy and he continued to hurry, as if he hadn't heard Yan Shan's strange tone, and not long after, an underground river channel more than two zhang wide appeared in the distance.

Although the river is not wide, the current is quite rapid, and it seems that it is only the smallest branch of the underground channel.

Before coming to the river, Bai Yi's face improved slightly, even the smallest river channel would indicate the direction of the way, as long as he walked along the river, he would have the opportunity to return to the ground.

Crash!

Before Bai Yi's footsteps could stand firm by the river, a black shadow suddenly churned out in the river in front of him, which turned out to be a strange man with a hideous face but lifeless.

Bai Yi always used his spiritual sense to perceive the surroundings, but he did not penetrate deep into the river, and the sudden appearance of the strange man surprised him, but after a while, Bai Yi returned to normal, took a few steps back, and did not even use the flying sword.

The one who leaned out of the water was a young woman, her face was pale, and she was wearing the Dao robe of the Hanyu Sect, and the most strange thing was that this female disciple of the Hanyu Sect actually only had the upper half of her body, starting from the waist, and it was actually covered with fish scales!

"Merfolk?"

Yan Shan's voice of surprise came from the jade pendant, this kind of legendary foreign object, even the thousand-year-old ghost king had never seen it.

"It's just a nun who has become food. ”

With Bai Yiqing's cold whisper, the female cultivator of the Cold Jade Sect suddenly opened her mouth, as if she was about to shout something, but she couldn't make a sound, and the fish scales under her suddenly stood up, completely enveloping her upper body, leaving only a head full of pain.

Click, click......

The scales on the nun began to squirm slowly, and then gradually sank into the water, and on the scales, a white fish's eye swept past the water.

It turned out that it was not a strange mermaid at all, but a cultivator who had half of his body swallowed by a strange fish!

Seeing the strange fish submerged in the water, even Yan Shan, who was a ghost, felt cold in his heart, this gloomy world was full of dangers, and if he was not careful, he would be buried in it, and there were probably very few monks who could get out of this underground world.

Keeping a distance from the river, Bai Yi picked up a low-level spirit stone and walked forward again, recovering the spent spiritual power while looking for an exit.

The river in front of him became wider and wider, and when Bai Yi walked out of more than three miles, the river was already ten zhang wide, and there were two branch rivers confluence on the road, which made the water flow of this river more rapid.

When Bai Yi walked to the end of the river, his eyes opened up in vain.

Ahead, there is still the underground world, but the space around it has become more spacious, and there is no edge in sight, and there is no end in sight.

The icy waters of the river rushed into the vast world and continued to flow far away, and in this open area appeared some unknown vegetation, all growing along the river, very dwarf, like patches of sparse wild grass.

Bai Yi's position at this time was still in the passage, and if he walked a short distance further, he could leave the passage and enter the open area.

Just as he was about to raise his footsteps, Bai Yi's eyes suddenly moved, and the flying sword was instantly sacrificed, hovering in front of his master.

Bai Yi sensed that there were many monks standing on both sides of the passage, and they were motionless, no one made the slightest sound, and if they didn't perceive it with their spiritual sense, they wouldn't be able to detect it at all.

Bai Yi did not move, but carefully sensed it for a long time, and his face became more and more heavy.

Outside the passage, there were hundreds of monks, all of them carved clay sculptures, breathing weakly, and their eyes were blank.

Suddenly, Bai Yi thoughtfully glanced at a stone wall less than three feet away from him.

The stone wall was on the left, and it was nothing but a few depressions.

As soon as the jade pendant on his waist moved, Yan Shan just wanted to speak, but the jade pendant was immediately covered by Bai Yi's spiritual power, preventing Yan Shan from speaking.

Glancing at the stone wall, Bai Yi lowered his head and groaned, not knowing what he was thinking, at this time, there was a strange sound of rubbing against the ground in the darkness behind him, as if something was crawling against the ground.

Looking back at the darkness behind him, Bai Yi's eyebrows tightened, raised his hands, and began to pinch the spell.

This time, Bai Yi's two hands pinched at the same time, and the spells in his two hands were completely different, and they actually cast two different Dao methods at the same time.

With the urging of the Dao Method, Bai Yi's body gradually faded, and finally disappeared completely, and the aura of his body was even more covered by the Dao Technique, and there was no trace of it.

The technique of invisibility, after being cast, can conceal the body and turn into nothingness, it takes a strong spiritual sense to see through, and the secret method that can only be performed in the Jindan realm can be barely comprehended by some extremely talented monks in the foundation building period.

When Bai Yi performed the stealth technique, in the sunken stone wall, an undetectable spiritual power fluctuation faintly appeared, and soon disappeared again.

In addition to the stealth technique, Bai Yi also had another Dao technique, called the breath-holding technique.

Although the stealth technique is strange and extraordinary, it has a fatal flaw, that is, the form is void and the qi exists.

Void refers to the transformation of the body into nothingness, and the existence of qi means that the breath is still there.

Among the demon beasts in the cultivation world, there are many demon beasts with an extremely sensitive sense of smell, even if the cultivator uses stealth techniques, it is difficult to escape the tracking of the demon beasts, after all, after stealth, the body is not seen, but the breath will still remain, once the demon beast attacks in the direction of the breath, it can still kill the cultivator in the stealth.

The main effect of the breath-holding technique is to shield the caster's ontological aura, and after casting, the cultivator's aura will be completely covered, and it is often used to avoid demon beasts with a keen sense of smell.

Being able to let Bai Yi cast two concealment Dao techniques at the same time shows how terrifying the things crawling behind him are, and it didn't take long for this passage to be shrouded in a huge black shadow.

It was a huge maggot-like monster, gray, headless, and without eyes, and its body was full of folds, and with each distance it crawled, the ground it passed became a little shorter, revealing new dirt.

This giant monster insect is actually devouring the ground it passes by!

In the rustling sound of wriggling, the strange insect crawled to the end of the passage, raised its integrated head, sniffed left and right, and after the strange insect raised its head, it appeared a gap of different sizes at the bottom of its body.

Those gaps were all over the body of the strange insects, and each of them was full of fine fangs, which looked not only disgusting but also very terrifying, and it was these countless 'mouths' that devoured everything that the strange insects passed.
