"That's it!" Yun Fei glanced around with satisfaction, and took out the small black pebble from his arms.

After coming out of the Heavenly Spirit Tree Realm, Yun Fei mastered the method of using aura, and because of this, the "aura" possessed by Yun Fei's Xuan Qi has far exceeded before, and with this kind of Xuan Qi infiltrating the stone, Yun Fei can obtain this eight-grade Xuan Technique in a short period of time.

"Come on, let me see how big your appetite for the stone is!" Yun Fei sat cross-legged, the Xuan Qi in his body roared out like an angry dragon, and roared towards the stone.

The stone was quietly suspended in the air, absorbing Yun Fei's Xuan Qi like a bottomless pit. Except for a slight glow on the surface, there is no abnormal movement.

A vague figure appeared on the glowing surface of the stone, which swirled in circles around the stone, seemingly forever tired.

Yun Fei was extremely familiar with everything, and the fur he had learned came from the floating shadows that appeared on the surface of this stone.

Now, what Yun Fei wants to learn is the true essence of this eight-rank mystical technique!

From past experience, we can know that this is a protracted battle, and Yunfei is fully prepared.

Yun Fei's eyes were slightly closed, one hand pointed to the stone in front of him, and the other hand aimed at the Xuanchi under his feet, and a steady stream of Xuan liquid poured into Yun Fei's body from the soles of his feet, and then poured into the stones after the processing of his eight-grade exercises.

"Woo......" In the depths of the Xuanchi, the Xuan Qi is soaring, and Yun Fei is in full swing cultivating his Xuan Technique.

The milky white Xuanqi, which was originally extremely thick, turned into tiny wisps of pure Xuanqi after being processed and purified by Yunfei's processing plant.

Yun Fei was like an old monk in a trance, repeating the same action without hurry.

In the depths of the Xuanchi, the boring cultivation continued, and Yun Fei was in a state of deep cultivation, with no concept of the passage of time in the outside world.

I don't know how long it took, Yun Fei slowly opened his eyes, he looked at the stone in front of him, the blankness in his eyes flashed, and he changed to a look of surprise.

The original dark stone has completely disappeared, and has turned into a crystal clear jade. Above the beautiful jade, a small humanoid floating shadow was flying rapidly, looking extremely mysterious.

"Finally...... Did it succeed?" Yun Fei's voice was a little hoarse, and he tried to move his limbs, but found that his body was extremely stiff.

"It's so hard, time flies so fast. Yun Fei smiled bitterly, according to past experience, to reach this level, at least one had to not eat or drink, and meditate and cultivate for ten days before it was possible.

Yun Fei's heart moved, and the pale yellow earth Xuan Qi instantly flowed through his limbs and five bones, revitalizing Yun Fei's body.

"Whew......" Yun Fei let out a long breath, stretched his waist, and moved his muscles and bones.

"Now, let me see what is so magical about this eight-rank mystical technique. Yun Fei reached out and grabbed the stone, carefully examining the floating shadow above.

After a while, Yun Fei rubbed his head and asked helplessly, "Old ghost, are you still hiding from watching jokes?"

"Hehe......" the old ghost laughed, "Congratulations to the master, you have learned another eight-rank mystical technique." ”

Yun Fei shook his head and said, "I can't do anything about this thing, where did I get some eight-grade mystical skills." ”

The old ghost said: "The Xuan Qi needed for this stone is enough, and there is no clue yet, which means that it needs something else." ”

"What do you need?" Yun Fei couldn't help but ask, "It can't be an aura, right?"

"Master is wise!" the old ghost's playful voice sounded, "Since this thing is an eight-rank mystical technique, it naturally needs the iconic substance of a real realm powerhouse to be able to open it." ”

Yun Fei couldn't help frowning, sighed and said, "Alas! The pseudo-eighth-grade Xuanqi is not the real eight-rank Xuanqi after all, it seems that you still have to use the aura." ”

In fact, Yun Fei knew that using aura was the best way, but during this period of time, Yun Fei had deeply realized the importance of aura, and he was reluctant to use the aura in the dantian to open this stone.

"Alas, I didn't expect to work so hard for so long, and in the end, I still need aura. Yun Fei said with a look of regret.

There are so many spiritual energy in the dantian, and Yun Fei's method of accumulating spiritual energy is very slow now, every time he uses up a trace of spiritual energy, Yun Fei will feel distressed for a long time.

The old ghost persuaded: "Master, you have done a good job. Your pseudo-eight-rank Xuan Qi has lowered the requirements of this stone for spiritual energy a lot. Now, I can tell the master the good news in advance. ”

Yun Fei asked listlessly, "Oh, what good news?"

The old ghost said: "For now, this eight-rank mystical technique in the master's hand is quite similar to the "Shadow Martial Technique". ”

"What do you mean? Are you saying that these two mystical techniques are equally powerful?" At the mention of the eight-rank mystical technique, Yun Fei suddenly became interested.

The old ghost explained: "There are two ways to inherit the Eight Rank Mystery Technique. One is like the "Qi He Tianyuan Stick" left by the old master, this kind of mystic technique requires the inheritor to use mental skills, coupled with dozens or even hundreds of years of hard work, before he can learn; ”

"You mean, as long as I open this stone, the eight-rank mystic technique in the stone is actually not difficult to control?" After listening to the old ghost's narration, Yun Fei's heart suddenly became hot, he looked at the stone in front of him, and a trace of determination flashed in his eyes.

"Come on!" Yun Fei endured the pain and cut his love, and pulled out a wisp of purple qi from the depths of the green dantian, sending it to the stone in front of him.

After ......the wisp of aura entered the stone, the stone began to tremble, and the floating shadow on the surface of the stone also flowed faster and faster.

After a while, the stone was quiet again.

"What? or no?" Yun Fei gritted his teeth and summoned out a wisp of aura again.

"Bang!" the second wisp of aura entered the stone, and the stone exploded, and a colorful floating shadow popped out of it and swept into the air.

"Master, chase after you, don't let that shadow run away!"

The old ghost's shouts exploded in Yun Fei's heart, and Yun Fei chased after him in the air without even thinking about it.

The speed of the floating shadow of "Whoosh...... was extremely fast, and it disappeared into Yun Fei's eyes in the blink of an eye.

"Damn!" Yun Fei couldn't help but burst into a foul mouth, he had worked hard to instill ten days of Xuan Qi, and he had also cost Yun Fei two wisps of spiritual energy, and it was gone in the blink of an eye!

"No! we have to catch up!" Yun Fei made up his mind, even if he chased to the end of the Xuanchi, he would have to chase this eight-rank Xuan Technique.

"......" Yun Fei's figure cut through the white mist at the height of the Xuanchi and came to the highest point of the Xuanchi space.

"There!" the old ghost instructed Yun Fei to look upwards to the right.

Yun Fei turned his gaze and saw a colorful floating shadow hovering high in the sky.

"That thing...... Trapped in a space barrier. The old ghost was meticulously observant, and at once he spotted the walls of space around the floating shadow.

"This thing is so fast! In the blink of an eye, it has reached the edge of this Xuanchi space. Yun Fei was secretly surprised in his heart, and after seeing that thing was trapped in the space barrier, his hanging heart gradually relaxed.

The old ghost said with palpitations: "In the final analysis, this thing is just an eight-rank mystical technique, and without the control of a real realm powerhouse, it can still turn the sky upside down!"

"It's good that I didn't run away. Yun Fei slowly swept towards that side, he could clearly see the existence of the spatial barrier, and he didn't have to worry about accidentally falling into the spatial barrier.

Soon, Yun Fei came to a position not far from the colored floating shadow, looking at the colorful floating shadow close at hand, Yun Fei couldn't help but smile bitterly: "This thing is really a scourge. I don't even know what it is, and I've already wasted two wisps of aura. ”

The old ghost smiled and said, "Master, don't be busy scolding first." You're about to use up the third aura. ”

"Alas!" Yun Fei sighed, and once again summoned a wisp of aura from the dantian, Yun Fei wanted to pierce a hole in the space barrier, but he still had to use the aura to do it.

Yun Fei condensed the transparent color Xuan Qi into a needle shape, and the needle position lingered with a touch of purple, and slowly leaned towards the spatial barrier.

"Poof......" A slight sound sounded, and the needle pierced a small hole in the spatial barrier, and the colorful floating shadow trapped in it immediately rushed out along the small hole, and wanted to flee into the distance.

"Hmph! I still want to run!" Yun Fei snorted coldly, grabbed the floating shadow, and swallowed it into his stomach without saying a word.

Yun Fei's heart moved, and the transparent colored Xuan Qi wrapped in the colored light and shadow went straight to Yun Fei's legs along the meridians, and then the Xuan Qi faded, and the colored light and shadow slowly dissolved into Yun Fei's legs.

"Infernal Step"!" The colorful floating shadow entered the body, and the name of that mysterious technique also appeared in the sea of Yunfei at the same time.

The mysterious technique created by the real people before the Great War of Gods and Demons is an eight-grade mysterious technique that pursues the ultimate speed, and if it is used by high-level real people, it can reach a terrifying speed that ignores space!

"No wonder it's called "Infernal Step", it turns out to be so powerful. Yun Fei couldn't help but sigh in admiration.

"How's it going, master, are you happy?" said the old ghost's voice.

Yun Fei said cheerfully: "Then you need to say, of course I'm happy." After getting "Infernal Step", Yun Fei completely left the three wisps of spiritual energy he had lost.

The old ghost said in a strange voice: "Master, since you have learned "Infernal Step", then hurry up and use it now." ”

"No hurry, no hurry. I'll wait until I've studied it seriously and mastered the mysteries of this mystical technique. The old god Yunfei replied on the ground.

"The hosts. The old ghost's voice was a little hoarse, "You better do it now, I'm afraid it's too late." ”

"When is it too late?" Yun Fei asked in surprise.

"See for yourself!" said the old ghost thoughtlessly, and then fell silent completely.

"What look?" Yun Fei looked up blankly and glanced around.

"Oh my God! this is ...... Space collapses?"
