Youlan Mu's figure flew upwards uncontrollably, the strong air flow blew in his ears and made a "whine" sound, the hot mist sprayed on his face like a fire, and the wound on his back was oozing blood beads under the blowing of the wind.

Seeing that he rushed to a position only five meters away from the top of the cave, the huge formation pattern seemed to detect an attack, the surface fluorescent flashed, and a hazy yellow defensive enchantment appeared at the edge of the formation, quickly closing towards the center like a thin film.

"Broken Army, it's about to crash into the barrier!" Youlan Mu shouted.

"Don't worry, you can't bump into it." Po Jun said it very confidently.

At the moment when the defensive barrier was about to close, the broken army suddenly burst out with a shout, "Forbidden!" The defensive enchantment seemed to be blocked for a second, and the broken army teleported along with Youlan Mu and the beast egg, passing through the rock wall at the top of the cave and directly entering the power tower.

Tao Ying, who was standing in the distance, was dumbfounded, as if she couldn't believe what she saw, that person had disappeared with the beast egg!

"Whew!!" The unicorn dragon that had lost its target began to go berserk, spitting fireballs and frantically attacking everything around it, including the yellow defensive barrier.

"Knock~Knock~" A huge explosion sounded, the sound was deafening, and some fireballs shot straight towards Tao Ying's location.

Tao Ying's face changed several times, and finally quietly retreated, although she lost one beast egg, she still had two in her storage bag.

The beast egg cannot be stored in the storage bag for a long time, otherwise it will die, and the beast egg also needs to be instilled with aura with a secret method, otherwise it will reduce the success rate of the beast egg hatching, and she must return to the master immediately, otherwise all her efforts will be in vain.

Tao Ying took a deep look at the direction in which Youlan Mu had disappeared, and then fled quickly to the north, rushing out of the world of flames and plunging headlong into the dark black mountains in front of her.

Entering the inside of the power tower, Youlan Mu was immediately surrounded by a huge aura, and his spirit was suddenly shocked, and the pain in his back was also reduced a lot.

The little black panther in his arms also seemed to notice the change in the aura outside, revealing his little furry head and taking a deep breath greedily.

Looking around, it was an enclosed cylindrical room, small in size, with hard black crystal slabs on the walls and floor. In the middle of the room stood a three-meter-thick dark black column, the height of which was unknown.

The black cylinder was printed with strange formation symbols, and the column rotated slowly from left to right, like an unlit marquee. The outside of the cylinder is also covered with a transparent crystal cover, which is very peculiar.

Looking up, the dark black column stretched upwards, hidden in a dark curtain, making it impossible to see the top. The aura like green smoke under his feet came out from the black crystal slab, and with the movement of Youlan Mu, it floated around, as if walking in the clouds.

Youlan Mu also noticed that with the crystal cover as the boundary, the aura on the outside was pale red, while the aura on the inside was dark red, and it was obvious that the concentration of aura in the crystal cover was much higher than that outside.

"Breaking the army, is this the power tower? How does this dark black cylinder look so much like graphite? Youlan Mu asked.

"That's right, this is a power bar made of high-quality graphite and other precious minerals, and the aura is absorbed by it and converted into spiritual power to be transported to other places. Seeing that the crystal cover on the outside of the power rod is not, its function is to prevent the aura from escaping outward, and only in and out is allowed. Pojun explained.

"Woo~" Suddenly there was a cry of the little black panther behind him, Youlan Mu turned his head to look and saw that the little black panther was fiddling with the beast eggs, and from time to time he stretched out his scarlet little tongue to lick it on the smooth eggshell.

Only then did Youlan Mu notice that the bottom of the milky yellow beast egg was a little scorched, and when he stepped forward to take a look, his brows immediately furrowed.

The eggshell was scorched, presumably caused by the egg falling into the lava. Youlan Mu also noticed that there were some cracks in the blackened shell at the bottom of the egg, but there was no egg liquid flowing out, which was a very bad phenomenon, indicating that the egg white at the bottom of the egg was likely to have been scalded.

"The beast egg fell into the magma, although it was not completely shattered, but the heat had already been transmitted in, coupled with the impact of the previous magma splash, the yolk inside was shattered, and it was impossible to hatch a unicorn dragon." As confirming Youlan Mu's guess, Po Jun made a positive conclusion.

"So its value has plummeted, and it can't be exchanged for Tsukidan?" Youlan Mu asked painfully.

"It can be cooked and eaten, and the egg liquid in it is also a rare tonic, containing a lot of spiritual energy, which can improve people's physique."

Youlan Mumo was a little reluctant to hold the eggshell, and in the blink of an eye, he passed by him as soon as he worked hard to build a kidan. The little black panther squatting on the side had his eyes shining, wagging his furry tail vigorously, and looked at Youlan Mu with expectant eyes.

"Boom!" Suddenly, the power tower trembled, and a loud bang came from beneath his feet.

The power bar flashed fluorescently, the rotation speed suddenly increased, and the runes on the power bar lit up in order, and began to absorb the aura in the crystal cover, and it can be seen that the color of the aura in the crystal cover was obviously lighter.

"Whew!" Another angry roar came from under the black crystal slab, and when he heard it, Youlan Mu's face changed, the unicorn dragon hadn't left yet, and was actively attacking the power tower!

When the little panther heard the roar, he was so shocked that his fluff exploded, his claws exposed, and he looked around in horror, as if he was looking for the source of the dangerous aura.

"Boom!" The whole room shuddered again, shaking the dust between the black crystal slabs on the walls.

"Breaking the army, will that unicorn dragon break through the defenses of the power tower?" Youlan Mu asked with a solemn expression. If the unicorn dragon was allowed to break through the defensive barrier of the power tower and blast open the rock formations beneath his feet, then he really had no place to stand.

"Don't be nervous, although that big guy has two hits, it can only run rampant on the ground, and its attack ability against the air is average, so when it gets tired, it will leave."

"Is it really okay, what if it attracts the elders of the sect, after all, it is attacking the power tower." Youlan Mu thought of another question.

"It's troublesome, it's okay, look at me." The broken army laughed and stopped moving.

You Lanmu felt a cold air flow through his legs, drilling out from the soles of his feet, and he couldn't help but shiver a little from the cold.

In the lava world below the power tower, the unicorn dragon threw its head back and spewed huge fireballs into the defensive barrier, and clusters of hot fireballs exploded in the air. Suddenly, a few snowflakes floated down from the thick black smoke, and gently landed on the sharp horns of the unicorn dragon, and the unicorn dragon's pupils shrank, and he looked at the snowflake that had not melted in surprise.

In this scorching magma world, snow or ice is impossible, and there is a snowflake lying quietly on the bridge of its nose, and the unfamiliar coldness makes the unicorn dragon vigilant.

At this moment, large snowflakes began to fall on the roof of the cave, like the snow of early winter in the flame hell staged a continuous dance of ice and fire, like a dreamlike scene that made the unicorn dragon open its mouth in horror, and it was difficult to make a sound.

However, what made it even more horrified was that the snowflakes circled left and right in the air to form a face full of majesty, spanning a distance of more than 100 meters, and on closer inspection, it was exactly the same as the broken army.

Po Jun slowly opened his snow eyes that were tens of meters long, and glanced at the unicorn industry dragon, causing the latter to suffer a cardiac arrest.

"Get out!" Majestic and domineering shouts rumbled through the space.

Feeling the unique spiritual pressure of the superior, the fear in the eyes of the unicorn industry dragon became stronger, and finally he couldn't resist the dazzling eyes of the broken army, and fled far away with his tail between his legs.

The giant face in the air smiled mysteriously, instantly turned into ten thousand snowflakes, and fell into the air.

In the power tower, Youlan Mu sat cross-legged, untied the bandage on his right hand, and began to practice the fire velvet technique with the dark blue dark pattern as the main body. A little bit of aura began to gather towards the dark blue dark lines, attaching to the surface and emitting a faint red light. Suddenly, there was a soft "poof", and a small fiery red flame appeared out of thin air, writhing left and right on the surface of the dark blue dark pattern, extremely light.

"The dark blue ghost pattern is really worthy of the belief of the Youlan clan, and it can condense the aura to this extent in such a short period of time." The broken army praised.

Youlan Mu's divine consciousness is highly concentrated, and he uses the fire velvet technique with all his might, transporting the spiritual energy that is scattered into granules to all parts of the body through the meridians, providing flesh and blood and meridians to absorb it, and at the same time suppressing the operation of the sea of qi to prevent the sea of qi from swallowing this aura. With the deepening of Youlan Mu's cultivation, the skin on the surface of the body gradually glowed with a layer of ruddy luster.

The little black panther who was wandering on the side saw Youlan Mu closing his eyes and cultivating, sneaked to the side of the beast egg, while circling around the beast egg, while carrying the wet tip of his nose back and forth to sniff lightly, and finally couldn't resist the temptation of the beast egg, directly bit through the charred black shell at the bottom of the beast egg, and got in.

Youlan Mu devoted himself to the cultivation of the fire velvet technique, and for a long time, the pain caused by the fifteen rounds of spiritual power fluctuations caused by the meridians was gradually reduced, and some small scars on the meridians that were difficult to see with the naked eye were also slowly healed under the nourishment of the aura.

With the continuous inhalation of the fire attribute aura, every piece of flesh and blood, every inch of meridians was filled with an indescribable warmth, as if the whole body was full of strength.

At this moment, the dark blue and red lines were the same as a soldering iron, and the spiritual power vortex formed on its surface was frantically devouring the spiritual energy, and the flames in the center of the spiritual power vortex had skyrocketed to half a meter high, while on the other hand, the spiritual energy in the power tower was drastically reduced at a speed visible to the naked eye. Some of the fire attribute aura that had just been absorbed by the formation had not yet touched the power rod, and they were forcibly sucked away by Youlan Mu and merged into the flesh and blood.

A day later, the aura reserves in the power tower were suddenly reduced by one-third. Five days later, the power bar detected that the spiritual energy reserves in the power tower were too low, and began to accelerate rotation, and the runes on the power bar were all lit up, and the array patterns engraved on the cave wall to absorb the fire attribute spiritual energy were also fluorescent.

Dozens of miles away, the power chamber on the surface was in chaos.

"Power Tower 3 is running at full capacity, but it only provides half the spiritual power it normally provides." A white-clothed disciple sweated on his forehead.

"How is that possible! Quickly open the No. 4 Power Tower, and make sure to ensure the stability of the Flame Hell Exit Defense Enchantment. The elder sitting in the power room gave the order without hesitation.

"Yes!" The disciple was ordered to run away.

Sitting back in his chair, the elder rubbed his eyebrows with some headaches, and wondered, "What happened to the Flame Hell, how could the unicorn dragon suddenly riot and attack the exit of the passage in groups." ”

Before he could change his breath, the disciple shouted anxiously again, "The spiritual power output rate of the No. 3 power tower is less than 30%."

"What!" The elder suddenly stood up from his chair with a look of hell on his face.
