In a daze, Xiao Yu slowly opened his eyes and stared directly at the craggy stone wall on the top of the cave, as if he was thinking about something.

"It turns out ... I completely confused the way of condensing aura... Because of Ye Lao's guidance, Xiao Yu found that although he thought of the essence, he chose a completely contradictory way, which is why he was so tormented by the aura in his body.

"Hehe, what Master said is right, if I am fighting with people now, who will wait for me to compress the aura to the end? Xiao Yu laughed self-deprecatingly twice, then twisted his body a few times and slowly got up from the hot ground.

"Hehe, that broken Dan furnace is unlucky enough. Xiao Yu looked at the Dan furnace that was blasted into the stone wall by himself, and couldn't help but shake his head and walked over.

"Click... ”

Xiao Yu grabbed the two furnace ears and used a slight force to pull out the Dan furnace embedded in the stone wall.

"Looks like I'm going to have to spend some more time with you. Xiao Yu said that, and then pulled the Dan furnace and walked to the center of the cave.

Because he also knew that if the aura was compressed in the body, there would be countless meridians of its own that could be relied on, but if you wanted to compress the external aura to the extreme, it would not be as simple as just now.

"Whew... ”

After his body fully recovered, Xiao Yu let out a sigh of relief, and his eyes were resolutely fixed on the Dan furnace in front of him.

"If you want to compress the aura ... It feels a little similar to summoning a fire sword, but... Can a flame that has been condensed into a solid one be used for alchemy?"

As soon as the words fell, Xiao Yu stretched out his two fingers and summoned two crimson fire swords.

Then, with a slight force, he pressed the tip of his sword against the wall of the furnace.

"Ding... ”

With a crisp sound, Xiao Yu couldn't help but shake his head, and then dispersed the two fire swords, frowning and thinking.

"No, although the fire sword is also produced by compressing the aura, it can't be used for alchemy... It's also.,It's all solid, what are you burning?。。。 ”

"That is to say... The final flame compressed should be close to solid, but it must not solidify, so that it can have the characteristics of flame and maximize its power. ”

"Hmmm... That's how it should be... Try it!" Thinking of this, Xiao Yu used his dantian aura again, forcing the raging flames out of his palms.

"It's so scattered... Xiao Yu looked at the flames he spewed out covering a distance of one zhang in front of him, and couldn't help but shake his head and said to himself, "But what method should I use to compress the spiritual energy?"

As soon as the words fell, Xiao Yu accelerated the flow rate of the spiritual qi in his body, and at the same time, the two fire dragons that erupted from his palms also suddenly produced a burst of deflagration, but in addition to the area covered by the raging flames becoming larger, there was no condensation effect that Xiao Yu expected.

"No, how can you condense the flames without the help of external forces... After a while, Xiao Yu put away his aura again, frowned and fell into deep thought.

"There is no limit to the aura released, it is impossible to achieve the effect of compression in the body, the reason why the fire sword can be condensed and formed is because of the Five Elements Decisive Exercises, if you don't let the aura run along a specific route, it is impossible for me to compress the aura to that extent... ”

"But... Now, if I were to reinvent a set of meridian charts for compressing the aura by myself... I guess it's the Year of the Monkey and the Horse Month... ”

"Well, it looks like we're going to have to figure out how to find a way. ”

Thinking of this, Xiao Yu opened his eyes and continued to force the two fire dragons out of his palms, adjusting the amplitude of the spiritual energy output in his body, and carefully observing the changes in the flames.

However, a quarter of an hour later.

"No, no matter how you adjust the strength of the aura, you can't achieve the effect of condensation... It doesn't look like this path is going to work. ”

Xiao Yu rubbed his temples, and simply lay down on his back, staring blankly at the stone wall on the top of the cave.

"It's really hot enough in this place... ”

"If you keep ordinary people inside, you won't be able to bake them dry?"

"Even if you can't bake it, at least it will be dehydrated... ”

Xiao Yu muttered to himself thoughtlessly, in fact, he didn't know what he was going to do now, he just wanted to lie quietly on the ground like this.

"Water... Hehe, try it. ”

Thinking of this, Xiao Yu stretched out a finger, and after activating the aura in his body, a water ball the size of a glass bead appeared on his fingertips.

"Ahh ”

In the next second, the small water balloon was instantly evaporated by the surrounding heat, and even Xiao Yu didn't see how it disappeared.

"I'm going, so fast? Why don't I feel like it's so hot in this hole? Xiao Yuteng sat up suddenly, fanned the hot air around him a few times, and said in surprise.

"Come again!"

Immediately after, Xiao Yu held a water ball the size of a football on the palm of his hand, but in the next second, it was also evaporated by the surrounding heat in an instant.

"I rub ... Come again!"

This time, Xiao Yu did not summon the water ball again, but shot out a thick water dragon from his palm as if he had just spewed flames.

"Ahh ”

Although the amount of water sprayed this time was much larger than before, the water was still evaporated by the heat before it had evaporated far away.

"No... It's not the temperature ... But... However, this time, Xiao Yu finally saw how the water evaporated, and also found the culprit of this situation.

"It's a good thing that those raging fire attribute auras do... Could it be that it is because the two are mutually reinforcing, so they are crazy about encircling and suppressing the water attribute?"

Xiao Yuqing clearly saw that the two water dragons that he sprayed out turned into messy water droplets after they left his hand, as if they had been destroyed by something, and those water droplets were broken and turned invisible in an instant because they were fighting for themselves.

"Hmph... In that being the case ... Then master, I'll tease you!" After speaking, Xiao Yu made a fierce effort and shot a thicker water dragon out.

At the same time, Xiao Yu also controlled the flow of water in his hands, tried his best to avoid the encirclement and suppression of the surrounding fire and spiritual power, and fought his way out of the encirclement again and again, and was strangled again and again.

"Hahahaha, it's interesting, it's much more fun than playing games!" Although the water dragon in his hand may still live to a foot away, Xiao Yu didn't care so much, and he was still happy to fight against each other's fire spiritual power.

After about a stick of incense, Xiao Yu stretched out his arm again and sprayed a second thick water dragon from his palm.

In this way, Xiao Yu waved his hands and controlled the two water dragons to toss and turn, playing with relish in this empty cave.

"Bang!"

Suddenly, because of a momentary negligence, Xiao Yu actually collided the two currents together.

"Damn, this can't be controlled?!" Because of the low-level mistake he made, Xiao Yu couldn't help laughing at himself in his heart.

However, the two currents that collided in one place, because of the different angles of their convergence, began to twist and spin together, forming a thick whirlpool in the air.

"Hey?" When Xiao Yu carefully observed this whirlpool, he found that it magically broke through the limit of a distance of one zhang and extended directly to a place of about one zhang and a half.

"It's awesome! It's grown a lot. Xiao Yule said happily.

"Then work harder!See how far you can run!" With that, Xiao Yu controlled the flow of water in his hand and spun quickly in one direction.

As the speed of rotation increases, the length of the vortex slowly increases.

Two zhang...

Two zhang five...

Sanzhang...

Wuzhang...

After only a stick of incense, the whirlpool in Xiao Yu's hand actually extended to five zhang away, but at this moment, he directly put away the aura in his body and looked at his hands thoughtfully.

"This is because ... The power of the whirlpool after compressing the flow of water... ”

"If water could be compressed ... Why can't the fire?"

Thinking of this, an expression of ecstasy appeared on Xiao Yu's face, so he directly activated the fire attribute aura and spewed out two thick fire dragons.

"Let's go!"

As soon as the words fell, Xiao Yu controlled the two fire dragons to collide and rotate in a clockwise direction.

The speed of rotation became faster and faster, and the flame vortex became more and more condensed, and as time passed, a trace of black light appeared in the center of the vortex, Xiao Yu knew that it was the appearance of the flame after it was compressed to the extreme.

"Hahahaha, come again!" Seeing this scene, Xiao Yu laughed and continued to exert strength, and the flame vortex also produced more black light under his deliberate control.

"Boom!"

However, just as Xiao Yu was having fun, the tip of the flame vortex actually hit the stone wall of the cave and let out a piercing roar.

"Damn! Oh no, don't collapse the mountain!" The next second, Xiao Yu quickly dispersed the flames in his hand, and looked vigilantly at the inconspicuous hole in the stone wall, which was where the flame vortex hit.

"Whew... Fortunately, it's just a small hole. After a moment, Xiao Yu breathed a sigh of relief and continued: "But... The power of this flame vortex can be! It actually drilled a hole in the stone wall, and... The cut is quite good, not bad. ”

"Hey, hey... With this hand, it seems that the spirit absorbing formation can't be stopped. Xiao Yu crossed his waist and laughed, and an excited expression appeared on his face, because he didn't expect that he could find a way to compress the power of the flame in such a short period of time.

He then sat cross-legged and regained the aura he had consumed during this time.
