In an instant, the flame aura in his body immediately swelled up like a balloon that had been blown up, and in an instant, it turned from a small trace of aura into a flame dragon shape that faintly showed a terrifying dark red color, carrying a magnificent roaring momentum, and rushed straight towards the wind and thunder aura that was trying to break through.

Under the astonishing power exuded by the flame dragon, the wind and thunder aura, which was still alive and kicking, suddenly stopped bombarding the barrier and became a little hesitant. Under the suppression of the powerful fiery red aura, he trembled slightly, as if he felt a fear from his heart for the flame dragon.

Gao Yun secretly breathed a sigh of relief, and hurriedly urged the amazingly powerful flame dragon to forcibly break through towards the center of a silver-white wind and thunder aura team.

In an instant, the wind and thunder aura was like a group of herbivores on the open grassland, and it was attacked and encircled by a huge group of lions, and the formation was immediately chaotic and collapsed.

A large area of silver-white energy was quickly divided and surrounded by the red dragon, under the collision of terrifying aura, a circle of astonishing energy spread out like ripples of water, and the fiery red and silver-white aura were desperately entangled, but in a few breaths, the red aura would take the advantage, and the wind and thunder aura trembled, and the original dazzling light quickly faded at a speed within the reach of the eye......

Under the two-order change of the Flame God Forging Body Technique, in less than a stick of incense, the Flame Aura achieved a near-complete victory. The slightest wind and thunder aura was constantly devoured by the roaring flame dragon, and the ones who were lucky enough to escape were all refined by the terrifying temperature of the flames. Soon, one after another, the giant dragons dissolved into the torrent of spiritual energy again, and the mighty spiritual energy that was originally churning and jumping gradually returned to its original calm.

As the wind and thunder aura was completely refined and absorbed by the flame aura in Gao Yun's body, in the original crimson aura river, a lightning-like silver glow faintly appeared on the surface, accompanied by a slightly piercing thunder and lightning sound.

Gao Yun slowly opened his eyes and let out a long breath. In his dark eyes, a subtle flash of lightning flashed imperceptibly.

Feeling the wind and thunder aura faintly coming from the aura in his body, Gao Yun was a little excited, but also a little dissatisfied.

With only so much wind and thunder power, it seems that it is still far from the amazing power of the wind and fire god thunder!

Gao Yun shook his head slightly, took out another Feng Lei Dan from the porcelain bottle, looked at it intently, and swallowed it in one gulp......

In the firewood room, a trace of thunder and lightning flashed from time to time. However, Gao Yun had already covered all the windows in advance, so he was not worried about being spied on by others.

Gao Yun was sitting cross-legged in the open space in the center of the room, meditating on pranayama with his eyes closed.

He had just finished refining thirty Wind Thunder Pills, and although the process was quite smooth, and the refining was becoming more and more proficient, it was still a bit reluctant for Gao Yun's current cultivation to continuously urge the second-order qi technique.

However, the intense consumption of aura has also yielded fruitful results.

Gao Yunzhou's body was faintly shining with a hint of silvery-white moving luster, and if he looked closely, it was actually a small light of thunder and lightning, mixed with crackling wind and thunder.

Gao Yun slowly opened his eyes, and the originally subtle and invisible microscopic thunder in his eyes suddenly became mighty, and a sharp and domineering thunder and lightning aura instantly burst out of his eyes, shooting straight at a wooden stool in front of Gao Yun.

I could only hear a soft explosion of "snort", and the wooden bench was shattered by this seemingly subtle small lightning bolt and turned into a small lump of pitch-black debris!

Gao Yun was also taken aback by this powerful force, and felt that the wind and thunder aura was suppressed. Otherwise, one after another small lightning bolts will go out, and the firewood house will have to be demolished!

Gao Yun stood up and twisted his body slightly, and there was a crisp sound of bone friction in his body. After more than two hours of continuous refining, even if he was strong-willed, he felt back pain, leg and foot soreness.

After taking a short breath, he felt the flame aura mixed with the wind, thunder, and silver light in his body, and the surging feeling made him feel a little refreshed.

"Okay, the wind and thunder aura is done, let's go to the back mountain. ”

The Wind and Fire Divine Thunder unleashed by Master Flowing Fire made Gao Yun tremble and tremble all over his body just by thinking about it. If you cultivate in the room, you can't be sure what will happen, but Gao Yun subconsciously thinks that it won't be a good result.

What's more, for such a powerful hole card as the Wind and Fire God Thunder, Gao Yun doesn't want to be eye-catching. After all, if someone in the palace asked about the source of the spiritual formula, it would be really difficult to answer.

After all, the matter of Master Liuhuo must not be said, and it is easy for people like him to get such a high-level spiritual secret from someone who has no status and status.

Gao Yun changed into a black shirt that was not easy to detect, and went straight to the back mountain.

The entrance to the mountain pass in the back mountain is not far behind Uncle Feng's thatched hut. When Gao Yun was alchemizing before, he chatted with Uncle Feng about the back mountain, and also learned about the general situation of the back mountain.

Spirit beasts are rampant in the back mountain, and it is said that some disciples have found spirit beasts with nine star levels in it. Due to the frequent occurrence of disciples and even tutors entering the back mountain and disappearing immediately, in order to avoid unwarranted personnel losses, the palace master of the generation a few years ago directly ordered the back mountain to be designated as a forbidden area, and strictly forbidden anyone in the palace to enter.

But in addition, according to Uncle Feng, in order to refine the pill, and the distance is very close, he often secretly goes to the back mountain to pick some rare medicinal materials. As far as he saw along the way, it was very safe to enter the place close to ten miles from the entrance of the back mountain, and even the spirit beasts could not see a few, and after ten miles, he would encounter a cross-section canyon, and there was a broken iron cable wooden bridge connecting the two banks. As for the place behind the wooden bridge, he had never set foot in it, firstly, the medicinal materials within ten miles were enough for him to refine all kinds of pills, and secondly, he sensed a trace of dangerous aura from the distance on the opposite bank.

Therefore, Gao Yun thought about going to the back mountain to cultivate the Wind and Fire Divine Thunder, even if he made a relatively large movement, he was not worried that he would be discovered.

The sky is still dark, and the shadows of the trees in the dark mountain forest are longing, which is creepy at first glance. However, Gao Yun looked indifferent and rushed forward quickly. Having cultivated to the fivefold realm, he is no longer the hairy kid he was before, not only has his senses become very sharp, he is always aware of the things around him, but he is also well aware of the energy fluctuations within a few miles.

At the beginning of the short road, the wind and waves were calm, and it seemed that this back mountain was really a paradise. But after going some distance deeper, Gao Yun found that there were fluctuations of spirit beasts all over all directions, and it seemed that it was an impossible task to completely avoid spirit beasts and advance.

Gao Yun's expression was slightly solemn, he took out the long sword, and between the infusion of spiritual energy, the surface of the sword body was suddenly covered with a layer of dark flame sword, which was different from the past, and there was a faint silver electric light beating happily on it.

"Since we can't go through, we have to find a way. ”

Gao Yun whispered to himself, and in the next moment, his figure shot out like lightning, sweeping towards the side where the spirit beast's aura was weaker.

"Boom"!

There was a dull thud, and a brown spirit beast with a body that was about a foot long and covered in sharp hooks and thorns struggled slightly, and fell heavily to the ground. On the surface of his skin, thunder and lightning could be seen flickering slightly.

Beside the spirit beast, Gao Yun gently fell to the ground.

He glanced around, looking at the corpses of the spirit beasts scattered all over the place, and a smile appeared on his face.

Afterwards, Gao Yun sat down in the open space in the middle of the spirit beast's corpse and began to meditate on refining the spiritual aura light that flew out of the spirit beast's body.

After a while, Gao Yun opened his eyes and frowned slightly, along the way, he had already refined more than twenty groups of spiritual energy, but he didn't feel any changes in the spiritual energy torrent in his body at all.

Alas, the higher the rank, the more difficult it will be if you improve, and just killing some spirit beasts is no longer enough.

Along the way, he also carefully rummaged through the corpses of spirit beasts, and luckily found three beast souls and put them in the bracelet. Two of them are still fire-based, and after cultivating the Wind and Fire Divine Thunder, they can be taken back and handed over to the master.

Gao Yun pursed his lips, and with a tap of his toes, he rushed towards the clearing he had seen earlier.

After a short walk, he came to the bottom of a slightly empty valley. I1387
