Throwing aside the dark blue magic crystal in his hand, which was worth at least fifty imperial gold coins, Di Xue continued to walk forward calmly.

He has been walking in the underground world for half a day, this underground world is very wide, and Di Xue has walked for so long and still has not seen the end.

Along the way, he inspected a lot of magic crystals, and found that most of the natural magic crystals piled up in this mountain were still medium and low-level, and high-quality ones were still very rare.

Different from the natural magic crystal ores common on the mainland, the magic crystals in the underground world far exceed the ordinary magic crystal ores in terms of volume.

From time to time, you can see the crystal pillar that is taller than a person being inserted diagonally on the ground, this large magic crystal is not very high in quality, and it is not even as good as the artificial magic crystal, but its rare volume is still breathtaking.

It's like an abandoned treasure trove.

If it were an ordinary explorer who walked into this treasure house, I am afraid that he would have gone crazy for a long time, and every qiē here represents endless wealth, but Di Xue is naturally not a person who is short of money...... He didn't have the idea of emptying all the piles of magic crystals here.

And after exploring the underground world for some distance, Di Xue is more interested in the delicate plants that accompany the magic crystals than the magic crystals that represent endless wealth.

Flowers are rarely seen in the fog forest, and the vegetation in the dim fog forest is luxuriant, but most of them are weeds, trees, vines, etc., and the thorny thorns are even denser, and the delicate flowers are rarely seen.

Even if there are flowers, they are ugly and vicious man-eating flowers.

But in this underground world, where I don't know how deep it is from the ground of the fog forest, the further you go in, the more blossoming the small wildflowers bloom.

There are also dyed leaves and green branches that bear exquisite fruits, and many magical beasts feed on them.

Di Xue picked two ruddy fruits and tasted them, and found them particularly sweet and delicious.

There are several other underground rivers in the underground world that meander and flow, some of them are like the underground rivers that Di Xue saw at the beginning, and the water comes from the holes in the stone dome above, which should come from the fog forest on the ground, and some are pure underground water flows, all of which flow in the same direction.

To the distance, where the light blooms.

The soil beneath your feet became softer and softer, as if it exuded the earthy smell of the vast plains, and the grass and flowers became more and more flourishing, and the young birds whispered, and the fragrance of the flowers permeated the air, and the surroundings became brighter and brighter, making it hard to believe that this was in the underground world that was not deep above the ground.

What kind of existence is this?The doubts in Di Xue's heart became more and more as she approached the center of the underground world.

It wasn't until after walking a distance, bypassing a large mountain of magic crystals, that Di Xue finally saw the source of the radiant bloom, and he couldn't help but let out a sigh......

It's really beautiful.

The high stone dome cracked a huge crack in the distance, the crack was wide and long, as if the entire underground world was divided into two halves, and around the crack were gems as bright as a galaxy, and in the crack was a colorful flow of light, like the brilliant aurora on the sky dome of the arctic ice field in the legend of exploration.

Dozens of underground rivers converge from all directions, forming a huge underground lake under the cracks, the lake is as quiet as a mirror, reflecting the colorful colors and the black-winged elves dancing with a little golden light on the lake, and the wooden boats full of flowers row across the lake, and the reflection in the mirror of the lake is like a dream made by illusion magic.

And in the center of the lake, the giant tree stands tall for thousands of feet, the crack on the top of the stone dome, the vigorous and thick trunk is like a mountain, supporting the crown of the tree with a radius of many zhang, and the green leaves on it are dense, pieces of crystal, emitting a green light, and the light of thousands of green leaves gathered together makes the center of the underground world like a round of emerald sun hanging all year round.

"Ancient Tree of Life...... Di Xue muttered to herself, there was no doubt, this must be the Ancient Tree of Life of the Elven Clan, because only the Ancient Tree of Life can grow to such a huge size.

Just as Di Xue was deeply attracted by the beautiful scenery in front of him, there was a faint noise behind him.

The grass and wildflowers on the soft soil began to tremble, not by the breeze, but by the ground on which they had roots.

Not far away, there was a deafening roar accompanied by the light of the fire.

The giant tiger like a hill that Di Xue had seen from afar before came here with an incomparably fierce anger for some reason.

Di Xue gasped, this is a demonic beast close to the realm of the Beast King, and it is not easy to deal with it when it is obviously in a rage at this time.

The tiger roared and shook the stone dome, Di Xue was ready to avoid the route of this giant fire tiger, he didn't want to be attacked by such a powerful demonic beast for no reason.

But just as he had just taken the first step, the giant tiger shattered a pile of magic crystals, and suddenly smoke and dust rose everywhere, and a black figure appeared in the smoke.

The giant tiger was chasing the black figure, only to see the person rush out of the smoke and flying magic crystal fragments, and run rapidly on the ground, but just now it seemed that she was hit by a magic crystal fragment in the calf, and her running speed became slower and slower, and her steps were a little staggering.

Behind her was a pair of black butterfly wings, but her wings seemed to be injured as well, shaking weakly behind her back as she ran.

Looking at the pair of wings like black butterfly wings behind her, Di Xue knew that this was a dark elf, and it seemed that she was still a female dark elf.

Di Xue hesitated, wondering if he should save the female dark elf.

I don't know if it's a coincidence or not, Di Xue saw the female dark elf, and the female elf also saw him.

Perhaps out of the instinct of survival, the female dark elf screamed and ran in the direction of Di Xue, which resembled "the same kind".

“！@#￥%&*......”

The intermittent elven language came, Di Xue's face was full of black lines, this time he was saved even if he was not saved, he had learned elven language, and he could understand that the dark elf was shouting for help.

The giant tiger watched the weak female elf in front of him slower and slower, and roared proudly, not knowing if he was saying "You shout, you shout that no one will come to save your ...... if you shout and break your throat"

Di Xue didn't break his throat or nobody, but he had to recite a magic spell amid a deafening roar.

"Tranquil and gentle water breath, condensed pure ice spirit, in the name of my will, condense the power of ice protection!"

The giant tiger is obviously a fire-attribute demonic beast, and behind Di Xue is a gurgling underground river, where the water element is abundant, and water is the best way to resist fire, so he naturally uses a source water magic - "Ice Condensation Guardian".

The originally gently flowing river began to stir, it was the power of the spiritual will that was extracting the water element in it, and the water element in the invisible air around Di Xue became more and more abundant, and even his gorgeous black robe was dyed with a little water droplet.

The water elemental continued to converge, and the red blood red crystal on the spade staff became ice blue and crystalline, constantly exporting Di Xue's spiritual power outward, and the temperature around him also began to drop sharply under the effect of magic.

The moist water vapor in the air was compressed in one place in an instant under the action of spiritual power, and it was frozen before it could quickly turn into water again, and the purest water element extracted by the spiritual power in the underground river froze into cold and hard ice at a speed visible to the naked eye, gradually forming an ice wall behind Emperor Xue.

The ice flowers bloomed, and the ice wall continued to expand in the creabling sound of the ice, gradually enveloping the Emperor Snow, forming a hollow cone that shrouded him below.

The ice pick was close to forming in a matter of seconds, but Di Xue left a gap in front of her that could be used by one person.

The female dark elf who was chased by the giant tiger was almost out of strength during the flight, and her extremely pale cheeks were flushed with two unhealthy blushes from running, and she was only struggling to survive with the will to survive.

At this time, she saw that the black-robed man not far away seemed to be a very powerful magician, and she couldn't help but have a glimmer of hope in her heart, and her muscles barely increased a little strength in her trembling legs, and she ran towards Di Xue.

The giant tiger, of course, didn't want the female dark elf to be saved, and let out a tiger roar, opening its mouth to spit out a ball of fire in the chase.

Flames rolled from the fireball, and the crimson flames left death marks in the void and struck the female dark elf. Seeing that the ice pick Di Xue was in was already close in front of her, but the burning sensation behind her was getting stronger and stronger, the female dark elf closed her eyes in despair, and her body burst out with the last trace of strength and rushed towards Di Xue.

Seeing that the female dark elf was about to be hit by the fireball, Di Xue had no choice but to divide a trace of spiritual power, and the staff in her hand pointed at the fireball, and the front end of the fireball suddenly flowed with ice blue light, and the situation was critical, Di Xue had to spend most of her energy to maintain the magic ice pick of the talisman, and she could only cast a bachelor's primary source water system barrier in order to temporarily slow down the speed and energy of the fireball.

Fortunately, the fireball spit out by the giant tiger was only a breath of fire, and the fire elemental energy in it was not too strong, and the speed weakened by the weakening of the water magic of the Emperor Snow, and the fire light on it also faded a little.

At this moment, the female dark elf finally ran to the ice pick, and then rushed into Di Xue's arms.

Di Xue stopped her, and then her spiritual power suddenly came out, and the magic was activated, and the water element quickly froze, completely sealing the guardian ice pick in an instant.

However, in an instant, the guardian ice pick was fully formed, braving the slightest cold, enveloping Emperor Xue and the female dark elf inside, and through the frosty ice, two black figures could be seen embracing each other.

The fireball spit out by the giant tiger also hit the ice pick the moment it closed, but the power of this fireball has been weakened a lot by Emperor Xue's magic, and it only hit a few faint cracks on the ice pick, and melted some frost.

Immediately after the fireball, the giant tiger burning with flames all over its body also came to the guardian icicle of Di Xue, the ice pick more than two meters high in front of it was just like a child's toy, the eyes of the giant tiger were also a flame, its terrifying tiger mouth opened to reveal a row of sharp teeth, with its huge size, it looked very fierce and intimidating.
