Thunder Pool.

Lu Bei used his magic powers, and all the way down, the golden cyan light ball covered the clouds and mist formed by the thunder, and then stood above the void.

looked around, but saw the surrounding white thunder flashing sharply, dazzling eyes.

The white thunder arc kept swimming like a small snake, and a pure masculine and destructive aura filled the place.

At his feet, the white thunder water is not rippling, and there seems to be infinite killing opportunities hidden in the calm.

At this moment, the earth-shaking dragon groans sounded, and there was a bang...... The pure yang thunder water set off turbulent waves hundreds of feet high.

A hundred-foot-sized, silver-shimmering thunder dragon revealed a huge dragon body.

The horns of the thunder dragon dragon are magnificent, the dragon scales are as big as a silver basin, and the light and shadow on it are faint, and they are in a trance.

"Groaning ......"

The light and shadow suddenly condensed, and the two pale pupils of the thunder dragon suddenly shot out two bolts of lightning, and the dragon's eyes moved, as if there were three thunder lotus flowers blooming silently.

"Roaring ......"

The Ancient Thunder Dragon shook its head and tail, the dragon's mouth suddenly opened, and the thunder light balls flew and shot towards Lu Bei.

Lu Bei was stunned for a moment, not dodging or dodging.

"Click..."

The white thunder ball of light burst open, and one after another pure yang thunder slashed down on Lu Bei's body, but it was blocked by the floating life diagram.

"Van Lei?"

Lu Bei muttered, his eyes thoughtful.

And the Ancient Thunder Dragon seemed to see Lu Bei despise him so much, and he became even more angry.

Roaring angrily, while spitting out countless thunderballs towards Lu Bei again, the two claws quickly incited, and one after another thunder arcs and thunder blades appeared, attacking Lu Bei.

Lu Bei was a little impatient, raised his palm, and slapped it casually.

The primeval thunder dragon was caught off guard, and it hit a stumbling blow in the air.

"Ling...", the innate spirit treasure refining demon pot appeared in Lu Bei's palm, the mouth of the pot was suddenly open, faint and faint, like a whirlpool, and a great suction force that could not be resisted, sucked the roaring Taigu Thunder Dragon into it.

Seeing this, Lu Bei's face was strange, and he thought, this ancient thunder dragon ...... It's too unhelpful.

Thinking like this, he turned to think of something, and his face changed greatly, "The Ancient Thunder Dragon won't be refined by me, right?"

hurriedly put his divine thoughts into the demon refining pot that was running, and when he saw the movement in the pot, he was silent.

He made a move, and a crystal clear, chicken-sized thunder bead appeared in his palm.

The aura of the origin of the innate thunder overflowed in all directions.

"Whoa..."

Lu Bei's eyes were slightly surprised, and he muttered, "Dragon Ball?"

He vaguely understood, turned to look at the thunder pool under his feet, looked at the color of the thunder pool, and thought, "This thunder pool has a total of thirteen layers, I want to come to this thunder dragon...... However, we still need to go down and investigate. ”

With this thought, Lu Bei's figure flashed, and he quickly supported the defensive force of the floating life map, which was to dive towards the thunder pool.

And the further down you go, the wider the view.

"The reddish thunder pool?"

Passing through a line of red and white demarcation, Lu Bei looked out through the light curtain of the Innate Defense Spirit Treasure Floating Diagram.

But when I saw it, I was wrapped in a light red thunder water that could not see the edge.

"It seems that the color of each heavy thunder pool is different......

While he was thinking, not far away, a thunder dragon with a body of thousands of feet appeared with a dragon body that covered the sky and the sun.

The extremely oppressive momentum shrouded towards Lubei.

However, for what Lu Bei said, it was like a breeze blowing on his face, and he regarded it as leisurely.

Lu Bei's eyes flickered, his five fingers clenched into fists, and suddenly burst out, King Kong became a seal, and the vast mana rushed into the sky, invincible.

The red primeval thunder dragon was blasted away by a punch, but there was still a red ball of thunder light, which flickered several times and fell on Lu Bei's body.

"Crackling ......"

Although he was blocked again by the Floating Life Diagram, Lu Bei still frowned.

Sure enough, as he guessed, this thunder dragon was just the embodiment of the power of the Dao source, and each weight was different.

Thinking of this, he didn't delay, the Innate Spirit Treasure Demon Refining Pot was poured into the origin mana, but it was concocted in the same way.

And the red primeval thunder dragon flickered a few times in the thunder pool, and was included in the demon refining pot.

Before long, a glittering pale red thunder bead appeared in Lu Bei's palm.

The red thunder turned into a mist, and the red light flickered non-stop, which was very magnificent.

Lu Bei was silent for a while, and slowly took out another white dragon ball, and as soon as the two came into contact, they were abruptly blended!

Lu Bei's cold eyes flickered, and he was slightly shocked in his heart.

If you can really condense the dragon ball of the primeval thunder dragon and then refine it, it is impossible to say that you will be able to deduce the origin of thunder to the true innate realm.

At that time, it will not be Da Luo, but also Da Luo.

Lu Bei's original casual attitude was to become serious.

Dive down again......

The third weight, the red thunder dragon, flew with one punch, and the five breaths of the demon refining pot were refined into blood-colored dragon balls.

The fourth, the orange thunder dragon, three fists flew away, and twenty breaths of the demon refining pot were refined into orange dragon balls.

The fifth, the yellow thunder dragon, flew with four fists......

......

......

Until the ninth layer, a purple thunder dragon exuding the aura of the Great Luo Golden Immortal was wandering in the ninth layer of the thunder pool.

Sensing Lu Bei's breath, he suddenly opened his dragon eyes, his eyes flowed, and above the void, purple chains suddenly appeared, flying, circling, and whipping towards Lu Bei.

"Da Luo!"

Lu Bei's heart sank slightly, he didn't dare to make a hard connection, and when his figure flickered, he fled into the distance.

"Boom..."

However, the speed of the purple thunder chain was extremely fast, and there was still a split that landed on Lu Bei's body.

The Floating Diagram slowly unfolded, and the scattered and impermanent dark air flow was actually beaten by the purple thunder chains.

"It's not good..."Lu Bei thought in his heart, and a blue-purple diamond-shaped crystal suddenly flew out from the center of his eyebrows.

The power of Kunlun Mirror's movement instantly acted on Lu Bei's body, and he quickly left this place before the defense was broken through by the Floating Life Map.

In the sky above the Nine Thunder Pool, Lu Bei looked at the tumbling Thunder Pool below, his eyes uncertain.

He sighed softly, "Sure enough, if you want to cultivate the Thunder Dao outside the Five Elements Dao, it's not that simple. ”

Instead, he took out a thunder bead with overlapping and flashing seven-colored lights...... Dragon Ball of the Ancient Brontosaurus.

"Come to think of it, if the last purple dragon ball is integrated into it, I will use this as a basis to comprehend the innate thunder dao, and I should be able to complete the transformation of the origin of thunder from acquired to innate ......"

Lu Bei thought like this in his heart, and he was somewhat regretful.

The thunder dragon below with the aura of Da Luo Jin Immortal is obviously not easy to deal with.

And according to Lu Bei's observation, this primeval thunder dragon, even if it is the ninth layer, is not the true appearance.

It's just the source of the thunder, the Dao image manifested in the ninefold thunder pool, according to local conditions.

Moreover, when he returned, he found that the breath of the thunder dragon was recondensing!

Then, the tenth to the thirteenth......

Lu Bei thought about it, but couldn't think of anything, so he just muttered, "Since you can't go down to the thunder pool, let's do it for the time being." ”

Instead, he turned his gaze to the Seven-Colored Thunder Dragon Bead and said to himself, "If there is a lack of purple, let's call it the Purple Pole Thunder Bead." ”

Lei Zhu seemed to have wisdom, trembled a few times, flashed a streamer, and flew into the dantian.
