The dim underground world is full of unknown dangers, even in the Jindan realm, masters with mana do not dare to enter the depths of the underground at will, although Yuntian and the two have treasures, they must be careful in the underground world.

The unknown is often the most dangerous.

After making up his mind, Yun Tian would choose to cross the river quickly, otherwise it would not be good if he was attacked by a strong man on this side of the river, or if he was besieged by monsters and demons.

The dim underground world can't block the sight of Yuntian at all, and as soon as he breaks through the Manifestation Realm, he completely has the ability to see at night, not to mention that there are mysterious divine thoughts that can observe everything.

The water of the underground dark river is not an ordinary transparent color, but a faint black, although this black is light, but it is full of the oppressive aura of death, so that Yun Tian has to be vigilant all the time.

Flying at a height of more than ten zhang on the surface of the river, the violent river wind made Yun Tian's body sway from side to side, but there was no danger in Soxin. The rumbling water of the river is deafening, as if the river is a waterfall, which makes people have to admire.

The whirlpools on the surface of the river, layer after layer of waves, seem to write the great danger hidden in the river, and the lifeless water contains murderous intent everywhere.

The huge water vapor made Yun Tian's whole body feel refreshed, but most of the water vapor was blocked by the Taoist clothes and Yun Rou's gang qi, so they flew smoothly and steadily, and in the blink of an eye, the two of them came to the center of the dark river, that is, the place where the river was five hundred zhang above the river.

At this moment, the originally dim underground suddenly became even darker, and streams of dark clouds shrouded the surface of the river, as if a storm was coming.

The underground world is also like a world, with rivers, mountains, plants, monsters, demons and many other creatures and animals, and naturally there are wind, thunder, lightning and rain, but it is relatively rare, and it is not surprising.

Otherwise, it is impossible for so many plants and animals to survive underground, after all, ordinary animals and plants are inseparable from the water and food necessary for the body.

Unless the kind of animal or plant that cultivates to the Jindan realm and is called a "demon", it can reduce its dependence on the body, borrow the power of thunder to cultivate the body, go to the ground to cultivate, and so on.

As we all know, some animals because of their strong physical bodies, occasionally in the mountains, take what kind of fairy grass, the flesh is strengthened again, but also can develop the brain, produce mana, such animals, called "demons"!

After all, the human body, in the final analysis, is still weaker than some animals.

However, there are few monsters that can break through to the Jindan realm and step into a higher realm, and once a monster steps into the immortal realm and has an immortal body, the physical body can change at will, drip blood and be reborn, and it will change in a thousand ways.

This kind of monster in the immortal realm is the boundless mana, starting a sect, becoming a god and an ancestor, and juxtaposing with the Immortal Dao Sect, but this kind of monster is too few.

The heads of the demon sects such as the "Heavenly Demon Sect" and the "Extreme Yin Sect" are all peerless powerhouses alongside the heads of the four sects of the Immortal Dao.

"There is a storm, so let's cross the river quickly, and if there is thunder in the midst of the storm, and it kills us, we will be injured immediately. Seeing such a scene, Yun Tian did not hesitate, his heart moved, his speed increased by three points, and Yun Rou flew across the river.

The distance of five hundred zhang is nothing for the current Yuntian, it will be reached in a few jumps, not to mention Yunrou, you can fly there with a single thought.

But strange things, more than ten breaths passed, Yun Tian could only look at the other side of the river from a distance, no matter how he and Yun Rou flew, they were still hovering in the center of the river, and it seemed that they would never be able to fly to the opposite bank.

They're standing still!

At this time, the top of their heads was completely covered by dark clouds, and the clouds were getting thicker and thicker, and in the depths of the clouds, there seemed to be electric sparks flashing.

"It's not good, we seem to have strayed into the legendary space labyrinth, it is rumored that once we strayed into the space labyrinth, unless the kind of strong person who comprehends the laws of space, it is impossible for anyone to break through this invisible labyrinth, and in the end we can only be trapped alive in this labyrinth. ”

After a few more breaths, Yun Tian suddenly stopped, looked at the other side in the distance, and said expressionlessly.

The space labyrinth is an invisible labyrinth, like a chessboard connected together, after an entrance, there is an endless space fork, one after another, intersecting in rings, there is never an end, once entered, you will fall into it, there is no way back.

What's even more terrifying is that the spatial labyrinth has no shape, no color, is completely transparent, and has no reference at all, so it can only be circled inside, and then sink deeper and deeper, and finally die completely.

The space maze also has a nice name called the Death Labyrinth.

The person who strayed into it, unless he comprehended the law of space, would definitely die, but the person who comprehended the law of space was more powerful than the master of the immortal realm, how could he meet it in ordinary times.

The spatial labyrinth can only be encountered in ancient battlefields, spatial connection points, and places where the space is chaotic, but there is this kind of spatial labyrinth on this underground dark river, which is completely unexpected by Yuntian, and it is simply unbelievable.

The possibility of encountering the spatial labyrinth is smaller than that of encountering the master of the immortal realm, and now that they have been encountered by the two of them, their luck is really to the extreme.

The two of them encountered this spatial labyrinth at this time, which was both a challenge and a kind of luck for them.

If they can break through this spatial labyrinth, their cultivation, strength, and state of mind ...... It will definitely go further, this is a big challenge, and once you succeed, you will definitely get a big benefit.

But if it fails, the consequences are unimaginable.

Knowing that the two of them had strayed into the space labyrinth, although Yun Tian was taken aback and clearly felt that extreme danger was coming, he stood in the sky without moving, pulling Yun Rou with one hand and putting one hand on his chest, letting the old monk enter the meditation and enter a state of meditation.

In the face of endless dark clouds, thunder and storms, as well as a mysterious and invisible spatial labyrinth, Yuntian is as peaceful as a sleeping child.

Yun Rou on his side heard Yun Tian talk about the space labyrinth, and his heart was also shocked, and his qi condensed again, wrapping himself and Yun Tian tightly, and then closed his eyes, as motionless as Yun Tian, as if he was thinking of countermeasures.

You must know that there is no chaos in the face of danger, the catastrophe of killing is just around the corner, and you can still be calm and comfortable, this state is a mental state, not something that can be exercised by taking a panacea, it completely depends on your own potential cultivation, that is, your roots and qualifications.

You must know that Yun Tian has not yet begun to cultivate his spirit, and his spirit is so strong, if he cultivates his spiritual power, then his spirit will be so strong!

Faintly, Yun Tian suddenly had the demeanor of a master. Even Yun Rou beside him was the same, and an inexplicable aura on his body was slowly growing.

As we all know, the more dangerous a person is, the greater the potential to improve, and any master must go through countless life and death wanderings before he can sharpen his spirit as sharp as a knife.

If Yun Tian and Yun Rou were able to put their lives on the ground today, it would definitely be an immeasurable achievement for their cultivation.

"Boom!"

Suddenly, a muffled thunder came from the dark clouds above Yun Tian's head, and the powerful current made Yun Tian's body numb, but he was still motionless, as if he hadn't heard this earth-shattering, crying ghost and god loud noise.

Boom, boom, boom!

The rumbling thunder was accompanied by strong lightning, and the violent lightning illuminated the ground, and a huge whirlpool suddenly appeared on the surface of the huge dark river, and there seemed to be a huge presence in the center of the whirlpool.
