Cast their skills and enter the vast plains, low-level demons are still the most primitive way of living.

Small tribes are formed, inhabited by them, and when humans come, they will attack them in groups.

Looking up, each layer was not as oppressive as Liu Wuxian thought, the first layer was very high, hundreds of meters high, and there were many huge trees growing in the underground world, dozens of zhang high.

Most of these trees are dominated by black leaves, some bearing fruit on them, others are covered with rattans, all plants that Liu Wuxian has never seen before.

In addition to the demons, there are many demonic beasts underground, and they coexist with the demons.

These demonic beasts are not the same as the mysterious beasts on the ground, and the demon beasts and the mysterious beasts swallow the essence of the sun and the moon to evolve.

Warcraft absorb demonic energy, and the underground world is filled with demonic energy.

For the demons and monsters, this is their spiritual food, and for the human race, this is poison.

Absorbing too much demonic energy, human beings will cause confusion, and even slowly demonize, lose consciousness, and become demons.

Liu Wuxian was not worried, the demonic qi poured in, and was instantly absorbed by the Heaven Swallowing God Ding, converted into new energy, and penetrated into the depths of the Heaven Swallowing God Ding.

"Rub!"

The demonic qi in the Heaven Devouring God Ding suddenly erupted, like a storm, startling Liu Wuxie.

"What's going on, absorbing a large amount of demonic qi can actually strengthen the Heaven Devouring God Ding, making the demonic flame more and more pure. ”

This discovery made Liu Wuxian shocked, could it be that the Heaven Devouring God Ding was a Demon Ding?

Quickly ruled out this possibility, it can refine both spiritual energy and demonic energy, which is definitely not as simple as a magic weapon.

Since the demonic qi did not do any harm to himself, he could devour it boldly and boldly, and the demonic flames in the Heaven Devouring God Ding became stronger and stronger.

In the future, the speed of refining will only be faster.

When you enter the deep plains, you can see hordes of demons looking for food.

There is not much interest in hunting this kind of earth-level demon, and the target is the fifth-order demon clan.

The speed accelerated, and the crane dance was cast for nine days, like a meteor, disappearing in place.

A demon hadn't noticed Liu Wuxian yet, only to see a gust of wind blowing, and Liu Wuxian disappeared.

During this period, he also encountered those demons who didn't open their eyes, blocking the road and intercepting them, thinking that Liu Wuxian was just an ordinary person, but he was killed by Liu Wuxie.

The hot demon blood melted into the Heaven Devouring God Ding, turned into a pitch-black liquid, and poured into the Desolate World.

The Heavenly Dao Divine Book unfolded, and there was an extra black spirit pattern on it, representing the Demon Dao, and it was another sequence.

After a day, find the entrance to the second floor.

Most of the demon beasts entrenched in it are fifth-order and seventh-order demon beasts, so you have to be careful next.

The fifth-order demon clan is equivalent to the human True Dan Realm, the sixth-order is equivalent to the Tiangang Realm, and the seventh-order is equivalent to the Celestial Phenomena Realm.

The ordinary fifth-order demon clan was no threat to him, but it would be dangerous to encounter the sixth-order demon clan.

The first thing he did when he saw the seventh-order demon clan turned around and ran.

He is very strong now, and he doesn't dare to collide with the Celestial Realm.

The second layer is larger, and the rolling demonic energy overflows from the ground, and the area has become larger, but there are many fewer demons living there.

The strange thing is that the second layer is not plain, the ground is uneven, and there are many passages, more like underground labyrinths, and many passages have no idea what is inside.

The line of sight is blocked, and the next step is to look slowly.

Choosing a passage, Liu Wuxian plunged into it, and performed the Ghost Pupil Technique, with a panoramic view of the surrounding kilometers of distance, even if there were stones blocking it, it would not be able to block Liu Wuxie's sight.

The speed slowly accelerated, and before I knew it, I had entered the second layer of the semi-axis zone, and I didn't dare to approach the core.

The real core area, with the best environment, has long been occupied by the seventh-order demons.

"Whoosh!"

A black shadow suddenly rushed towards Liu Wuxian without warning.

The Ghost Pupil Technique was sacrificed, but there was still a loophole, and the Ghost Pupil Technique could only lock one area, and if there was danger behind him, he wouldn't be able to find it at all.

The black shadow suddenly burst out from the lower right corner, and the ghost pupil technique could only see the front, and it was difficult to guard against the sides.

"Whew!"

The evil blade suddenly slashed down, and a trace of black blood sprayed onto the stone walls on both sides, and a demonic beast more than one meter high fell to the ground, and was blocked by Liu Wuxie's sword.

"Blackstone Rhino!"

This is a type of Warcraft, they like to hide in the dark, their bodies can change color, turn themselves into a stone, and when a human passes by, they will suddenly sneak attack.

Sacrifice the Heaven Devouring God Ding, swallow the black stone rhinoceros into it, and turn it into thousands of drops of black liquid, which is too wild and true to have a demonic nature.

The next step was to be more careful, and the pace slowed down a lot.

After walking for about a cup of tea, the vision in front of me suddenly widened, and out of the passage, a small plain appeared, and a wide underground river appeared.

Several demons were drinking water by the river, and there were some powerful demonic beasts, frolicking downstream.

Liu Wuxie's eyes locked on the three-headed fifth-order demons, and one of the tasks was to kill the five-headed fifth-order demons.

The body quietly approached, so as not to startle the snake, this place is full of dangers, act carefully.

Under normal circumstances, the seventh-order demon clan lives in the core area and does not go to the position of the half axis.

From the entrance of the second floor to the center, it is called the Half Axis.

From the center to the entrance of the third layer, this is called the core area of the second layer, and this area has the most mellow demonic energy.

As long as Liu Wuxian does not cross the half-axis area, there will be no major problems with safety.

Like a predatory leopard, it suddenly stopped when it was still thirty meters away from the demons.

The three-headed demon seemed to have discovered something, raised his head, and his eyes roamed around.

After inspecting for a long time, he made sure that there was no danger and continued to drink the river water.

Right now!

Liu Wuxian was like a swift leopard, his body suddenly ejected, turned into a meteor, and disappeared in place.

Thirty meters away, in the blink of an eye.

The evil blade turned into a merciless sword light and disappeared in a flash.

Before the three demons could react, the sword light had already been cut down, and blood spurted out, staining the river red.

A black cloth flew out, wrapped the three heads, and put them in a storage bag.

The Heaven Swallowing God Ding was sacrificed, refining the three demon clans, and a large amount of liquid was poured out, and the true qi of the Taihuang was becoming more and more pure.

"Roar, Roar, Roar, ......Roar, Roar, Roar, Roar, T

Not long after the killing, several terrifying roars were heard from not far away, and there were many demons around, and they were lurking in the river.

"Not good!"

Liu Wuxian only cared about the ground, but he didn't expect that there were also demons in the river, and more than a dozen demons came out, if it was a fifth-order demon, one of them turned out to be a sixth-order demon.

More than a dozen demons jumped out from under the water and pounced on Liu Wuxie.

Not daring to fight, he fled into the distance as soon as possible.

In the underground demon world, don't fall in love with war, there are demons everywhere, once you are contained, you will soon be besieged by a large number of demons.

The most terrifying thing is that sixth-order demon clan, whose strength is very terrifying, comparable to the human Tiangang Fivefold Realm.

No matter how strong Liu Wuxie's strength is, he doesn't dare to fight with the master of Tiangang Five.

The demon race is huge, the speed is far inferior to the human race, the height of the second layer is far less than the first layer, there are caves everywhere, and they dare not fly rashly, so they can only choose to walk on the ground.

"It's dangerous!"

After entering the cave, after turning around, he finally entered a safe area, Liu Wuxian said secretly.

No wonder it is said that the underground demon world is full of dangers, and it is true.

Finding a clean place to sit down, resting, and running continuously is a test for the spirit and true qi.

Take out the five tasks, all of them are completed in the underground demon world, not necessarily one by one, you can intersperse with each other.

The five tasks are to kill five fifth-order demons, obtain a demon dragon egg, collect a demon flame grass, a blue blood beast magic pill, and a Xuanyin butterfly.

Each task is not simple, and Liu Wuxian wants to complete it in half a month, which is very difficult.

According to the difficulty of the task, the difficulty of stealing the magic dragon egg is ranked first, and the second is to catch the Xuanyin butterfly.

The other three tasks are relatively easy, the Demon Flame Grass depends on luck, the Blue Blood Beast is a kind of magical beast, extremely cunning, its blood is green, it should be used as a medicine guide.

After resting, continue to go deeper, hunting demons while looking for the whereabouts of the Demon Flame Grass by the way.

The underground cannot feel the changes of the sun and the moon, and can only calculate the time through the hourglass, and it has been underground for more than a day.

"Qiang Qiang ......"

There was a sound of weapons colliding ahead, only humans would use weapons, could it be that someone was fighting with the demons.

The underground world is intricate, and Liu Wuxian follows the source of the sound and slowly approaches.

Bypassing a stone wall in front of me, I saw a woman besieged by dozens of demons, all of whom were powerful, all of them were sixth-order demons.

The woman turned her back to Liu Wuxie, and she couldn't see her face, but she felt a little familiar.

The body was pressed closer to the corner of the wall, and the thirteen-headed demon let out a chattering laugh.

"A woman who hasn't played with humans for a long time, today I will torture you and eat you. ”

One of the demons let out a lewd laugh, and looked at the woman in front of him with unscrupulous eyes.

The woman screamed, her body reversed, and she happened to face Liu Wuxie and saw her face.

"It's her!"

Liu Wuxian said secretly.

The woman was none other than the woman sitting on Liu Wuxie's right side at the Xuanyu Auction House.

During this period, Liu Wuxian was kindly reminded several times.

In that case, everyone present was falling into the ground, and only she reminded Liu Wuxie.

"To save her or not to save her?"

Liu Wuxian stood in place, lost in thought.

It stands to reason that he has nothing to do with this woman, and if he makes a rash move, he may die at the hands of the demons.

Let him turn around and leave like this, and he couldn't bear it, after all, the other party reminded him a few times, although he didn't help himself.

Good and evil, Liu Wuxian is very clear.

After three breaths, Liu Wuxian made a decision!

"Save!"

If he leaves like this, I'm afraid he will feel guilty for the rest of his life.

The woman fell into the hands of the demons, and the result can be imagined, she was ravaged by more than a dozen demons, and finally slowly tortured to death, devouring the essence and blood in her body.

Saving people requires skill, and with his strength, he is definitely not the opponent of these demons, so he can only use skill.

took out a rune paper, quickly carved it with both hands, and the sixth-order spirit patterns jumped on the paper.

Use the spirit runes to blow up these demons and rescue the woman.

The space for the woman to move is getting smaller and smaller, and there are several colors hanging on her body, dripping with blood, and she is swept by the claws of the demons.

If it is not treated in time, the demonic energy on the wound will erode into the body.

Three breathing times, the spirit rune was successfully portrayed.

If people knew that three breaths would depict a sixth-order spirit rune, I am afraid that they would be scared to death.

For an ordinary seventh-order spirit rune master, it takes ten breaths to carve a sixth-order spirit rune at the earliest.
