The space beneath the lake in the forest.

When Lan Hua appeared near the barrier, Ba Xia was still lying on the side, enjoying the light of the barrier.

After chasing Baxia away, the Purple Fire Turtle glanced at Lan Hua.

Lan Hua nodded slightly and looked at the black dragon.

Black Dragon was unusually calm, after all, he had failed too many times before.

Lan Hua drew her bow and nocked an arrow, activating the Yin-Yang Heavenly Technique to its fullest extent. Her Yuan Power transformed into pure Yin Power, bursting forth from her body and surging into the Cloud Piercing Arrow.

The golden arrow piercing the clouds emitted a dazzling black light, which was caused by the condensation of pure Yin energy.

The pure Yin energy was still being injected, and the Cloud Piercing Arrow actually emitted a faint buzzing sound, indicating that the injected energy had reached saturation.

If the Yuan Power is activated again, the Cloud Piercing Arrow will be unable to withstand the pressure and will explode on the spot.

"Now is the time!"

He released the bowstring with his right hand, and the arrow, carrying a long burst of energy, flashed past and struck the barrier.

boom!

The collision of the two extremely powerful forces produced a devastating explosion, ten times more powerful than the previous one.

The ball of light from the explosion grew larger and larger, roaring outwards and kicking up a storm of debris.

"Earthquake!"

The lakebed shook violently, startling Baxia, who quickly grabbed the Purple Fire Turtle's legs and shouted repeatedly.

Not only were the Black Dragon and the Purple Fire Turtle shocked, but even Lan Hua was stunned.

The power of this explosion was almost comparable to the self-destruction of a Yuan Dan; it was practically a miniature nuclear explosion.

Suddenly, a black light burst forth from the shockwave, incredibly swift and exuding an aura of dominance.

"My inner core!"

The black dragon roared and immediately flew up to grab the shooting inner core.

"After waiting for a thousand years, my inner core can finally be united as one!"

Black Dragon was excited, a hint of fanaticism in his eyes.

Before Lan Hua could congratulate him, the black dragon swallowed the inner core in one gulp and then sat down cross-legged.

The Purple Fire Turtle laughed and said, "Brother, why have you become so impatient? You want to fuse the inner core right now!"

The black dragon closed its eyes tightly, clasped its hands together, and a surge of black demonic energy erupted, forming a sphere of light that enveloped it.

The black orb of light grew brighter and brighter, and the black dragon's aura grew stronger and stronger, making it look somewhat eerie.

At this moment.

A small black dragon slowly appeared on the top of the black dragon's head, swimming rapidly around its body.

Lan Hua was somewhat surprised, because that small dragon was the primordial spirit of the black dragon.

Sudden.

The swimming dragon roared, emitting a dazzling light, and a slight change occurred.

The small horns began to grow and become two dragon horns. Four limbs also grew on the dragon's body, with four claws on each leg.

Lan Hua was shocked. "The black dragon is transforming into a dragon!"

"I never imagined that the black dragon's cultivation had become so powerful that it was actually about to transform into a dragon!"

The black dragon suddenly opened its eyes, and its body transformed into a gigantic dragon, hundreds of feet long, swimming in the bottom space of the lake.

Although the lakebed is spacious, it is still not enough for the black dragon to roam freely.

"roar..."

The black dragon roared and charged toward the spatial exit.

Although his primordial spirit has transformed into a dragon, his physical body is still that of a jiao (a type of dragon). Only when his physical body also transforms into a dragon can he be considered to have truly transformed from a jiao into a dragon.

Lan Hua and the Purple Fire Turtle exchanged a glance and quickly followed them out.

As the two rushed out of the lake in the forest, the black dragon continued to dance in the air above the lake, emanating a terrifying aura.

All the beasts in the Southern Boundary Forest were alarmed, gazing longingly at the black dragon soaring in the sky.

Suddenly, the sky was filled with swirling clouds and wind.

The once clear sky was now covered with dark clouds, and faint rumbles of thunder could be heard.

"This is... the Dragon Transformation Tribulation!"

The Purple Fire Turtle was greatly surprised, "Brother Black Dragon, be careful!"

"I know!"

The thunder grew louder and louder; the tribulation was imminent.

"roar..."

At that very moment.

Several earth-shattering dragon roars echoed from the horizon.

Two enormous golden dragons emerged from the void, piercing through the dark clouds and hovering above the terrifying lightning.

The two dragons roared and suddenly charged at each other.

Just as Lan Hua was filled with doubt, the two golden dragons faced each other, their tails connected, forming a huge circle.

The two golden dragons suddenly froze, as if they had turned into jade, only radiating boundless golden light.

The Purple Fire Turtle exclaimed in surprise, "That's... Dragon Gate!"

"Brother Black Dragon, once you overcome the Dragon Transformation Tribulation and pass through the Dragon Gate, you will become a true member of the Dragon Clan!"

At this moment, Lan Hua was filled with utter shock and disbelief, her mind reeling. "This is the transformation into a dragon! This is the Dragon Gate!"

Rumble!

A bolt of lightning suddenly struck.

That thunderbolt was a full half-zhang thick, enough to destroy mountains and split the earth.

The black dragon roared, showing no fear, and charged towards the thunderbolt.

A silver lightning bolt struck the black dragon, causing it to shudder and its originally shiny scales to dim.

Fortunately, the black dragon survived.

However, that was only the first of the nine bolts of lightning.

Rumble!

Another thunderbolt struck, even more powerful than the first.

The black dragon roared and pulled through again, its thick scales having lost their luster.

The Purple Fire Turtle roared, "Keep going! Don't give up!"

The black dragon was determined and withstood eight bolts of lightning in a row, its skin torn open and its scales falling off.

Those thunderbolts were formed from the power of rules, and were a hundred times more powerful than ordinary thunder.

Lan Hua began to worry about the Black Dragon.

At this moment, the black dragon looked exhausted. The eight bolts of lightning had exhausted his strength, and he could barely fly in the sky.

With all the scales peeled away and his protective armor gone, how could he withstand the final bolt of lightning?

Rumble!

A flash of light appeared, and the last bolt of lightning struck.

That bolt of lightning was several times thicker than the black dragon's body; even a Yuanxiang Realm expert would be reduced to ashes if struck by it.

"I want to transform into a dragon..."

"Damn you, God! I've cultivated for over two thousand years, all for this day!"

"roar!"

The black dragon mustered its last bit of strength and charged toward the bolt of lightning.

boom!

The terrifying lightning engulfed the black dragon, tearing its skin and flesh apart, but not a drop of blood was spilled; it was all reduced to ash.

A strong burnt smell filled the air.

The enormous dragon's body seemed to lose its life, falling straight down into the forest lake, splashing up a sky full of waves.

"Brother Black Dragon!"

The Purple Fire Turtle cried out, its voice filled with sorrow.

There was no movement in the lake for a long time.

Lan Hua sighed, "Did the dragon transformation fail?"

Looking up at the sky, the thunderclouds dissipated, leaving only the Dragon Gate standing.

However, the brilliance of the Dragon Gate grew weaker and weaker, and it seemed that no longer they were looking forward to the Black Dragon's transformation into a dragon.

Suddenly, the low growls of countless beasts echoed through the forest, seemingly lamenting the Black Dragon's defeat.

Sudden.

The lake water flowed slowly, then grew stronger and stronger, and a huge body burst out of the water, flying into the sky and towards the Dragon Gate.

It was the black dragon that had survived the tribulation of becoming a dragon.

Purple Fire Turtle and Lan Hua were overjoyed.

After the black dragon passed through the Dragon Gate, countless rays of light shone on its body, causing an astonishing change in the black dragon.

A giant black dragon appeared, over two hundred feet long, exuding a terrifying aura.

"roar..."

After the dragon's roar, the black dragon flew to the lake and came to Lan Hua and the other person, transforming into a handsome human form once again.

In the Southern Boundary Forest, all the beasts bowed their heads, and once again, a loud roar resounded.

This is the reverence that all beasts have for the dragon race.

The Purple Fire Turtle laughed, "Brother Black Dragon, when you fell into the water, I thought you were going to kick the bucket!"

Black Dragon smiled and said, "Brother, I've already transformed into a dragon, so just call me Black Fierce!"

Lan Hua laughed and said, "You made us worry for nothing. Congratulations, Senior Hei Lie!"

Hei Lie looked at Lan Hua, smiled slightly, and with a wave of his right hand, a purple bead appeared in his palm, the bead burning hot.

"I was able to transform into a dragon thanks to you; otherwise, I don't know when I would have reached this point!"

"This is the inner core you wanted. It was given to me by Brother Yuan Tuo, who said it could help me overcome the Dragon Transformation Tribulation!"

"Thank goodness I made it through!"

Lan Hua accepted the turtle's inner core and said, "Thank you!"

Suddenly, two more objects appeared in Hei Lie's right hand.

Lan Hua was taken aback. "Senior Hei Lie, what do you mean by this?"
