The crane shuttled fiercely into the cracks in the ground, and at the same time, Yun Rou and Yun Tian took out a set of silver-white robes and put them on their bodies.

This costume was given to them by Liu Yun when he was leaving, and they were all high-grade treasures, with amazing defensive power, even if they were Jindan masters, they couldn't break it. With this suit to protect them, they are absolutely safe in this underground world.

The deeper into the ground, the light became more and more dim, the yin wind roared on all sides, and from time to time it was accompanied by a few strange roars, and the basin-sized bats showed a fierce light, constantly attacking Yuntian and a crane, but they were easily solved by Yuntian.

After a few breaths, Yun Tian and the two fell to the ground steadily, Yun Tian seemed to say something to the crane, the crane let out a long roar, and flew outside, leaving only Yun Tian and Yun Rou in the empty underground.

Of course, the two of them were accompanied by countless dangers lurking in the dark.

The underground abyss world is not entirely dark.

The land of the abyss is no different from the ground, there is fertile black soil everywhere, and there are many streams, tall plants, and even mountain waterfalls and flowing water.

Except that they were dark, with no sun, moon, or stars, they were not much different from the terrestrial world, and these tall plants were mostly mushrooms and a large glowing grass.

Some mushrooms are like giant umbrellas, dotted with stars, like fireflies, emitting a soft light, bringing a glimmer of light to the abyssal world underground.

This mushroom is called the luminous mushroom, which can only grow underground, and can not see a trace of sunlight, if a person cultivates to the realm of manifesting the gods, with the help of this trace of light, he can have the ability of night vision, although Yuntian is only practicing the physical realm, but in this underground, he can also see far away.

Moreover, this underground world is a good place for cultivation, in the dark, there are endless dangers hidden, and many demon beasts will kill you at any time.

It is the best cultivation method to hone one's spiritual will here, it is easy to develop one's potential, and to be in danger all the time.

Because this statement can be proved from one thing, half of the true disciples of the True Yuan Sect were cultivating underground before they reached the Jindan realm. It can be seen how great the underground role is.

More importantly, the underworld is rich in mineral deposits, such as 10,000-year-old cold iron, ink crystal, underground underworld crystal, earth crystal, turquoise stone, sea tide jade, Tianhai bone, yuan magnet, green earth...... And so on the ground rare treasures.

These materials are all necessary materials for refining flying swords and magic weapons, and they can even assist in cultivation and enhance people's spirits.

Moreover, the demon beasts in the ground are strange, and the blood of some demon beasts is a good material for refining pills, such as a kind of flying purple blood spirit snake that only grows underground, and the blood of this spirit snake can increase the strength of the flesh after refining into pills.

In the underground world, in addition to all kinds of monsters and minerals, there is also an underground indigenous inhabitant, the underground demons, that is, the earth demons.

"Big brother, is this underground, it feels fun!" Looking at the scenery in all directions, Yun Rou was a little stunned, attracted by the "good-looking" scenery here.

"Fun, don't you think!" Yun Tian shrugged his shoulders and said seriously, "Rou'er, there are many demon beasts in the underground that are good at sneak attacks, and there are countless poisons, although you have a strong qi to protect your body, you must also be careful, and always pay attention to the movements around you, so as not to have any accidents." ”

Yun Tian held a long sword in his hand, this long sword was not a magic weapon, but an ordinary "weapon", yes, it was a long sword made of mortal iron, because there was no trace of mana fluctuation on this long sword.

Yuntian is Liu Yun's son, so he naturally has a powerful magic weapon, but he is here to practice now, if he directly takes out the treasure flying sword, then it is almost an invincible existence in this underground, what kind of experience is it?

Sure enough, as soon as Yun Tian's voice fell, his back suddenly became cold, his face turned cold, his feet stepped on the ground, and a backhand sword slashed out, and the sword light seemed to be extremely closed in this dim underground.

Woo!

There was a scream behind him, and a one-man tall demon beast was slashed to the ground by the sword, rolled twice, and then stopped moving.

When I looked at it, it turned out to be a giant wolf with blood-red fur like flames, and the teeth of this giant wolf were deeply exposed, as long as fingers, as sharp as a stone could bite off.

It's an underground blood wolf.

"Underground Blood Wolf" is a unique underground monster beast, with excellent eyesight in the dark, sharp teeth can bite all rocks, and even can bite steel, eating people is even chewing bones into powder and devouring them, and the speed is as fast as lightning, extremely cunning, and good at sneak attacks.

If the master of the Manifestation Realm is not guarded, he will also be bitten to death.

But I didn't expect to be killed by Yun Tian with a sword, and he couldn't die, which shows how sensitive Yun Tian is to the things around him, how skilled he is in mastering power, and how skilled he is, to the point of being superb.

"Well, I know, I'll be careful, big brother, you have to be careful!" Yun Rou also saw this blood wolf, but when she saw that Yun Tian was fine, she was relieved, and at that moment, her anger gushed out, and she wrapped herself tightly, not daring to be careless.

"En!" Yun Tian nodded, his eyes and ears were all directions, holding the long sword in his hand, and he slowly walked towards the depths of the ground with Yun Rou.

The blood wolf is full of treasures, and the huge wolf skin is worth a thousand gold, and many dignitaries and nobles are proud to wear a blood wolf skin coat.

The reason why the blood wolf is called the blood wolf is naturally for a reason, there is a parietal bone on the top of the blood wolf's head, called the blood crystal, which contains extremely strong blood and qi, after ordinary people wear it, it can make up for the body's qi and blood, and it is also a material for refining many pills, magic weapons, and spiritual weapons.

However, Yun Tian didn't care about this thing, and he didn't have that much time to collect the blood wolf's fur and blood crystals, these things were of no use to him.

After Yun Tian left for a few breaths, several blood wolves appeared in the place where he was standing, and these blood wolves did not attack Yun Tian and the others, but devoured the corpse of this dead blood wolf, which shows how cruel the blood wolf is.

Sizzle....... Sizzle..........

Suddenly, several colorful poisonous snakes jumped up from the grass and bit Yun Tian and Yun Rou, these poisonous snakes emitted a colored poisonous gas all over their bodies, and wherever they passed, even the ground was corroded, which showed how poisonous this poisonous snake was.

Seeing this group of poisonous snakes, Yun Tian swung out an expressionless sword, and the sword momentum was like an ethereal star, cutting off the heads of several poisonous snakes and staring at the ground.

The headless snake writhed and then turned into puffs of poisonous gas that dispersed into the air, while the ground was corroded into several one-foot-deep caverns.

If Yun Tian is bitten by these poisonous snakes, the consequences can be imagined, Yun Rou looked at these poisonous snakes, her face was slightly sideways, her fingers moved, and the Biyun sword was in her hand, and she stabbed to the side.

As soon as the sword momentum fell, the two demon beasts like tigers let out two screams, and even the blood was evaporated by the sword qi.

"Good!"

These two demon beasts, Yun Tian also found out, the reason why he didn't kill them was naturally to see Yun Rou's reflexes, Yun Rou's performance was expected by him, he sighed, and walked forward.

"Hey, hey!"

Yun Rou smirked, followed Yun Tian, and walked towards the depths of the earth, where there were still many unknown dangers waiting for the two of them.

The underground world is not destined to be peaceful!
