Reaching the Vientiane Realm, even within a smaller realm, the gap feels like an unbridgeable chasm. Even those famed geniuses of the Cang Mang Continent cannot fight across realms.

Though the Five Elements Chaotic Thunder Tribulation Dragon Transformation Technique is formidable, at its core, it is still a Heaven Rank Divine Skill, even if it combines insights from the Heavenly Dragon Palace and the Thunder Dao.

It can only contend with ordinary Vientiane Realm Dao Venerables and the Demon Race Demon Monarchs.

Facing the Black Dragon Demon Monarch, this move is evidently somewhat lacking.

If it hadn't been for the Heaven-Swallowing Ancient Mirror absorbing most of the attack, Jiang Shu might have already been gravely injured.

If the stalemate continues, it might attract other Demon Monarchs of the Demon Race.

After all, this is not the Endless Sea within their Cang Mang Domain.

But the Chaotic Demon Sea of the Demon Domain!

Various thoughts flashed through Jiang Shu's mind.

At this moment, True Monarch Black Dragon felt a twinge of unease. Jiang Shu himself wasn't particularly fearsome.

His worry was that Jiang Shu coming to the Demon Domain, with treasures given by the Supreme Sect Leader of the True Martial Sect, deploying methods one after another, might force him to retreat continuously. 𝘧𝘳𝘦ℯ𝓌𝘦𝒷𝘯𝑜𝑣𝘦𝓁.𝒸𝘰𝓂

Not to mention, in this Chaotic Demon Sea, he wasn't the only Demon Monarch guarding the barrier.

If other Demon Monarchs arrived, would he have to share the spoils?

He must resolve this quickly!

Decision made, the Black Dragon Demon Monarch's demon energy surged, cutting sharp traces in the space like a razor's edge, drilling into the void, sealing the heavens and the earth to close off all of Jiang Shu's escape routes.

Jiang Shu summoned the Heaven-Swallowing Ancient Mirror into the sky, its surface like a black hole, relentlessly absorbing the surrounding rampant leftover demonic power, even swallowing the light.

He took a deep breath, reaching the peak of his essence, energy, and spirit, with each acupoint in his body shining brightly, illuminating like the stars in the sky. His blood and energy burned like a furnace, and he slowly grasped the void with his right hand, as if opening the heavens and earth.

During a century of cultivation in the Wenxian Palace, he spent almost all his time understanding the Panwu Great Strength Dao Book, gaining a deeper understanding of the Power Dao.

Now, it's time to test everything.

His aura, vast as the heavens.

The Black Dragon Demon Monarch also noticed the change in Jiang Shu, with indigo flames igniting in his ominous dragon eyes, as his myriad demonic power transformed into overwhelming flames, condensing into a gigantic dragon identical to himself, silently snarling and charging at Jiang Shu.

This flame was extraordinary, chilling to the bone. Even True Monarchs who had passed the Wind and Fire Tribulation in the Nirvana Realm would be burned upon contact.

"Dying by my hand isn't a wasted life!"

The Black Dragon Demon Monarch roared, with his demon energy reaching its zenith.

Evidently, he was undergoing a complete eruption.

In the void, Jiang Shu's expression was calm, surrounded by Dao Rhymes. Ten Great Dao floated above his head, with the Power Dao hanging high like a brilliant sun.

The other nine Great Dao, like cascading Milky Ways, surrounded the Power Dao, with endless power channeling into it.

Under the ten Great Dao, Jiang Shu seemed to turn into jade, with blazing flames refining a giant axe.

Every acupoint in his body resonated, pulling countless forces into his right hand.

In the many Great Dao, the Power Dao ranked extremely high.

There's a saying that power alone can suppress all laws.

Once fully understood, it could even cleave the heavens and the earth.

Within the same realm, he would have no equal.

Even when fighting across realms against the Black Dragon Demon Monarch, he could still put up a good fight!

Before, he refrained from using it for fear of losing control due to excessive exertion, over-extending in battle, which might draw other Demon Monarchs.

Now it seems, he must gamble!

"This power... Jiang Shu, didn't you just advance to the Vientiane Realm?"

Seeing the giant axe forming before him, the Black Dragon Demon Monarch's vast eyes flickered with doubt.

Instinctively, he sensed a thread of danger.

Yet Jiang Shu was clearly displaying his own abilities.

Could he still pose a threat?

"Slash."

Jiang Shu's voice was calm, yet it echoed throughout the world.

The axe light spanned the heavens and the earth, seemingly able to split the sky, severing the space it crossed without any sign of healing, as if this was predestined, confined by an irresistible force.

This slash, the power of Jiang Shu's other nine Great Dao all infused into the Power Dao.

The terrifying power erupted with a bang.

The Black Dragon's fire, originally roaring over the Chaotic Demon Sea and more terrifying than the Nirvana Tribulation Fire, was completely cleaved apart under the brilliant axe light, with sparks scattered like fireworks falling in all directions.

This axe light's power completely surpassed the Black Dragon Demon Monarch's understanding.

In his pupils, all the light seemed to converge into this axe light.

An incomparable killing intent, advancing without retreat.

"Boom!"

The heavens and the earth became one!

Over the Chaotic Demon Sea, endless waves rose from this point, with some surrounding islets shattered entirely by the immense force.

In the void, golden-yellow dragon blood sprayed, dripping from the sky.

Each drop, like falling volcanoes, burned on the Chaotic Demon Sea.

Enormous roars echoed in the sky amid painful howls.

If someone looked up, they would see the massive black dragon originally coiled in the clouds, bleeding.
