Youlan Mu took out the only low-grade spirit sword and cut it horizontally on the slightly hardened lava, in order to prevent the spirit sword from breaking again, he carefully controlled the fluctuation of spiritual power, maintaining it at a level of about three rounds.

The spirit sword cut out squares of the same size on the dark lava surface, and then slashed horizontally underneath the sword, and with a slight pick of the tip of the sword, a square rock brick was made. As concocted, after some labor, Youlanmu cut out more than 400 rock bricks.

"Boy, what are you trying to do, build a ladder? How long will this take? Seeing Youlanmu's actions, Po Jun questioned in a wordy manner.

"Almost, just look at it."

Youlanmu encloses a slightly larger circle with rock bricks on a flat lava, leaving a certain gap between each rock brick, and then begins to lay the second layer of rock bricks, there is still a gap between each rock brick, and as the number of layers increases, a hollow chimney gradually takes shape.

"You're a stupid idea, how many bricks do you have to pile up to get to the top of the cave?" The number of broken troops fell off the road.

"You have the ability to think of a way." Youlan Mu bent down and picked up two rock bricks, and snorted dissatisfiedly.

Suddenly, Youlan Mu's palm ached, and he let go of his right hand in shock, and the rock bricks fell to the ground with a dull sound.

Looking down, a small opening was made on the edge of his right palm, and a lot of blood flowed out.

"Pounce~Pounce~" You Lanmu noticed that the rock brick that fell to the ground was still beating.

He cautiously stepped forward and turned it over, only to see a hideous fish head exposed on the surface of the rock brick, and the sharp teeth in the fish's mouth were still opening and closing up and down. Youlan Mu took a breath of cold air, what the hell is this?

Youlan Mu didn't recognize the strange fish, but the little black panther did, crawled out of Youlan Mu's collar, jumped to the ground, bit the fish head, and swallowed the fish head only when he heard the "click".

Youlan Mu rubbed the little black panther's round head dotingly, and said in surprise, "It's strange, why can't you see the shadows of other large spirit beasts around here?" ”

"What's so strange about this, either the living environment here is harsh, and there are few spirit beasts moving around, or this is the territory of a powerful spirit beast, and other spirit beasts don't want to approach." Po Jun said lightly.

"Why didn't you remind me earlier!" The second half of the sentence made Youlan Mu vigilant, and the movements in his hands immediately sped up by a point. If he really accidentally broke into the territory of a certain spirit beast, it would be fine to be able to fight, but if he couldn't, he would be in trouble. And he was still worried that the spirit beast would collapse the hollow chimney he had worked so hard to build.

"You just go faster, you can't finish it without a day's work, and the higher you build this chimney, sooner or later it will attract the attack of spirit beasts, I guess you can't build this chimney." Po Jun came to a conclusion that made Youlan Mu very unhappy.

"And what do you have to do?" Youlan Mu frowned and asked.

"It's not easy, just find a spirit beast with a larger body, lure it here, and then you can step on its back. The one-horned karmic dragon that I encountered when I first entered the Flame Hell was not bad, and it was big enough. "Po Jun came casually.

Youlan Mu was stunned for a moment, his face was as black as the bottom of the pot, and he suppressed the anger and said: "Is this an idea that people came up with, this idea is too rancid." ”

The little black panther who was lying on top of Youlan Mu's head and breathed a "woo" very cooperatively.

"Bad idea? I don't know how many times stronger this idea is than yours. Pojun protested loudly in Zhihai.

Ignoring the nagging of the broken army, Youlan Mu is like a diligent ant, carrying rock bricks back and forth between the chimney and the ground, when Youlan Mu uses rock bricks to build a hundred meters high, suddenly the earth trembles violently, and Youlan Mu, who is standing on the chimney, almost falls down because of the violent shaking of the chimney.

"Knock, knock, knock~" The shaking on the ground became more and more frequent, and its sound became louder and louder, as if a giant beast was approaching here in the distance.

The little black panther lying on top of Youlan Mu's head immediately stood up, looked at the depths of the south in horror, and went directly into Youlan Mu's arms.

Youlan Mu raised his head to look in the direction where the sound came from, and at the junction of the earth fire and the cave roof in the distance, a huge spirit beast the size of a mountain rushed over.

It had a stout horn on the bridge of its nose, its limbs short and thick, and its long, jade-shiny tail swaying from side to side as it moved. Every time it ran forward, the earth trembled.

It's a unicorn dragon! Seeing the appearance of the spirit beast clearly, Youlan Mu was suddenly shocked.

"Break the army! You crow's mouth! Seeing the unicorn dragon running in his direction, Youlan Mu scolded and hurriedly climbed down the chimney.

Despite its huge size, the unicorn dragon can run at all its strength no less than a cheetah. In the blink of an eye, the unicorn dragon had run hundreds of meters, moving straight in the scorching magma, disturbing the viscous magma and splashing it everywhere.

Youlan Mu noticed that there seemed to be a streamer at the ankle of the unicorn dragon, which looked like gold and not jade, which was completely different from its rough skin, could it be that this was the reason why the unicorn dragon was able to move in the magma at will?

Suddenly, Youlan Mu found that there seemed to be a white figure running rapidly in front of the unicorn dragon, because he was too concerned about the huge body of the unicorn dragon, and for a while, Youlan Mu didn't even notice the existence of this person.

When she got closer, Youlan Mu saw the appearance of the comer clearly, with curved eyebrows and big eyes, a small nose, a tightly bound white dress highlighting a streamlined figure, a slender ponytail is easily reminiscent of the little girl next door, and an oval egg in her arms adds a touch of naughty taste to her.

Yes, naughty to the point of cardiac arrest.

Youlan Mu still remembers the introduction of the unicorn karmic dragon in the jade slip, with thick skin and hard armor, strong defense, fire lotus as the main food, lazy temperament, rarely take the initiative to attack humans, and there is a small note at the end of the message, "Never try to provoke an adult unicorn dragon!" ”

Youlan Mu never thought of provoking the unicorn dragon, but the rampaging unicorn dragon still came to him for trouble.

"Whew!!" The unicorn dragon's angry roar rumbled through the vast underground world, as if the whole world was trembling along with it.

After Tao Ying successfully stole the egg of the unicorn dragon, she ran wildly all the way, and saw a black building suddenly built on the flat lava surface from a distance, and there was a vague figure busy back and forth on it, Tao Ying, who was chased by the unicorn dragon, immediately rushed there without hesitation.

Tao Ying waved her hand as she ran, "Big brother, help!" ”

Youlan Mu's face turned pale, her heart jumped, she turned around and ran, not to mention a pretty little girl, even if the fairy beauty came, she couldn't let him turn around.

"Boy, what a run, what a chance! If you find a way to climb the back of that spirit stone, won't you be able to reach the top of the cave? Knowing the sea in the broken army shouted.

Youlan Mu froze for a moment, looked at the Roshan with fear, gritted his teeth and circled a large circle outside, trying to detour back to the back of the unicorn dragon. However, as soon as he ran out of an arc, a snow-white egg flew through the scorching flames and flew straight towards Youlan Mu, and a clear and gentle shout came from the distance, "Big brother, run!" ”

“**！” Youlan Mu couldn't help but burst into a foul mouth, and subconsciously caught the beast egg, if he accidentally let the beast egg smash in front of him, Youlan Mu was sure that the unicorn dragon in front of him would definitely chase him to the ends of the earth.

"Whew!" Seeing that the egg thief and his helper still had a helper, the unicorn dragon roared angrily, and rushed towards Youlan Mu with trembling steps, and on the way, he directly knocked down the chimney that Youlan Mu had worked so hard to build.

Youlan Mu frowned, put the beast egg on the ground, and prepared to leave quickly, he didn't want to be hated by the unicorn dragon.

Seeing Youlan Mu's actions, Tao Ying exclaimed and shouted, "Big brother, don't!" That egg can be exchanged for a Tsukidan. ”

Tsukidan?! Youlan Mu froze in his feet, picked up the beast egg again, spread his speed, and ran with all his might.

The unicorn dragon originally saw Youlan Mu put down the beast egg, and had the intention of retreating, and a nervous heart suddenly relaxed a lot, but when he saw Youlan Mu picking up the beast egg again and fleeing, the unicorn industry dragon was instantly angered to the extreme, as if Youlan Mu's behavior was to tease it and provoke it naked.

The unicorn dragon roared, and a fireball with a diameter of three meters erupted from the depths of its throat, smashing straight towards Youlan Mu.

Sensing the movement behind him, Youlan Mu immediately turned to counterattack, tried his best to lower his body, and avoided to the left, and the scorching fireball flew over Youlan Mu's head, exploding ten meters away.

"Boom!" The entire roof of the cave trembled with the sound of a violent explosion, and some of the upside-down stone pillars broke off and fell into the air. The scorching wave of air pushed Youlan Mu a big heel, shaking his chest, and the beast egg in his hand also flew out and fell into the magma lake in the distance.

"Knock, knock~" The unicorn dragon stepped on a heavy step and rushed to a position only a few hundred meters away from Youlan Mu, and the surface of the surrounding lava shook a fine ripple as it ran.

"Hurry up! It's coming! An anxious shout sounded in the distance, and Tao Ying stood in a safe position with a pale face and shouted loudly.

Youlan Mu shook his head that was a little dizzy, and saw a layer of red fire burning on the edge of the beast pill soaked in magma, and he was shocked, and hurriedly got up and wanted to go over and fish out the beast egg. The value of this beast pill is comparable to a Tsukidan, which is a wealth that Youlan Mu cannot ignore coldly.

Seeing that Youlan Mu was still approaching the beast egg, the unicorn dragon erupted a second fireball in anger.

"Boom!" The fireball exploded behind Youlan Mu, and the surging heat wave slapped heavily on Youlan Mu's back, sending Youlan Mu flying out like a leather ball.

Youlan Mu's body shook violently, spitting blood, and landed on the magma lake in front of him, seeing that he was about to fall into the lava, suddenly his body moved three meters to the left out of thin air, and landed steadily on the top of the beast egg, pushing the beast egg to slide forward for several meters.

Tao Ying in the distance was suddenly stunned, and directly moved three meters horizontally without the help of a spiritual weapon, what kind of exercise is this! Could it be teleportation? But isn't that a secret method that only the strong in the infancy stage can do? The next scene made her speechless in shock.

A large puff of hot gas suddenly erupted from the magma underneath the beast's egg, and as the magma on the surface rolled, "Boom!! With a loud bang, a large amount of lava splattered outward from the ground, and the powerful heat current pushed the beast egg, blowing the beast egg into the air with Youlan Mu!
