How strong is the power of the Fourth-tier Martial King level?

Previously, Su Xiaobai could only sense it vaguely, but now, as the master of this power, he could tell you very clearly… strong, extremely strong — it felt as if the entire world was within his grasp; even a casual slash could trigger a resonance with heaven and earth!

Moreover, the amplification brought by the shadow was comprehensive.

Whether it was cultivation techniques, power level, endurance level, agility level, and so on… all of them were being superimposed by an extremely high multiplier!

The most crucial point was that Su Xiaobai had cultivated so many techniques, covering almost every aspect, to the extent that his entire being had no weaknesses or flaws at all!

Boom! Boom! Boom! Boom!…

In just an instant, the clash between two Fourth-tier Martial Kings triggered a doomsday-like scene.

Massive saber beams, each spanning tens of thousands of meters, rained down at a rate of thousands per second. Yanxuan had nowhere to dodge and could only choose to meet them head-on!

But he was not willing to be outdone either.

As he swung his massive twin maces, fire and metal attributes bolstered his strikes, also causing the heavens to collapse and the earth to shatter!

The two battled fiercely in the skies ten thousand meters high.

Endless lights flickered and danced across the sky.

Flames, frost, lightning, poisonous mist, darkness… all kinds of elements were pouring out madly!

The deafening roars filled the world, pounding into everyone's ears — it no longer looked like a mere fight but rather the signs of the destruction of stars!

"What's going on with this Sculpted Moon Azure Dragon…"

"Just now he was struggling even to withstand a single blow, so how is he suddenly able to go toe-to-toe with Lord Yanxuan?!"

"Not to mention, the number of techniques he wields is simply overwhelming… just among King-level techniques, he has three, and over a dozen Transcendent-level techniques, many of which are even of the highest grade!"

"With such talent, forget 'Ninety-Nine Mountain Passes,' even the 'Thirty-Three Layers of Heaven' might not be able to stop him!"

"If he advances a bit more in realm and level, getting onto the 'Vast Chaos Ranking' would be no difficult task!"

The six-winged birdman with dark golden eyes was shocked beyond words; monstrous waves surged in his heart, and even his dark golden pupils trembled!

Such a world-shaking, unparalleled prodigy, even in a place like the Vast Domain, would be incredibly rare… so how could one possibly be born in a barren and feeble place like Earth?!

"But this is exactly my chance to act!"

After his initial shock, the six-winged birdman did not forget his mission.

He couldn't deal with Sculpted Moon Azure Dragon.

But the other humans on Earth could not stop him at all!

If he wanted, he could easily sweep through all human Martial Kings single-handedly!

Puff!

Just as the six-winged birdman was preparing to act, a golden light suddenly shot through the back of his head, piercing his forehead and taking his life before he could even react!

The golden light retracted — it was a long spear emitting a golden glow. With a sudden flick, all the blood on it was shaken off.

The lifeless body of the six-winged birdman fell helplessly.

Behind him appeared a tall man in a white martial robe, his long black hair flowing in the wind.

He made no sound, concealing his aura completely, silently watching the fierce battle between Su Xiaobai and Yanxuan in the distance.

"Hmm?"

Meng Qianzheng seemed to sense something.

His gaze shifted from the battle and instantly noticed the man in the white martial robe.

His face immediately showed a look of joy. Just as he was about to bow respectfully, the man in white smiled gently and waved his hand, signaling him not to.

The commotion here also attracted the attention of other human Martial Kings.

When they followed the gaze and saw the man in the white robe, they couldn't help but grow excited and stirred, all wanting to bow, but were similarly stopped by the man's wave.

Still, someone couldn't help but whisper excitedly, "I knew it — the City Lord would definitely appear!"

That's right.

The man in the white robe was none other than the strongest among Earth's humans — the one who had rescued humanity from the brink of destruction multiple times, the mysterious founder behind the first human organization established secretly in the Vast Domain — the Lord of the Forbidden City, Luo Yu!

Luo Yu's life was nothing short of legendary.

Before the Great Cataclysm arrived, he had already, through a unique method of Qi refining, surpassed all humans on Earth, becoming the first to reach the unprecedented Martial God realm!

It must be known that at that time, even the strongest beings on Earth, those who claimed themselves as 'deities', were only at today's Demi-God level of Martial Commanders… almost everyone believed that the world was shackled, and no further breakthroughs were possible.

But Luo Yu shattered the shackles in one leap, achieving true Martial Godhood and becoming a truly transcendent deity — it was from then on that the "Martial God" realm was recognized.

When the space fissure first appeared, it was also Luo Yu who, with the body of a Martial God, crossed through the rift and discovered the Vast Domain.

However, this also exposed Earth's humans to the Siwu Clan.

Luo Yu often blamed himself, feeling that it was his own momentary curiosity that brought disaster upon humanity…

Thus, he trained desperately, risking his life repeatedly to save humanity, while also adventuring through the Vast Domain, growing ever stronger — to the point where he had now surpassed Martial King and became a Martial Emperor, someone even the Siwu Clan deeply feared!

It was because of him that the Siwu Clan had yet to launch a full invasion of Earth… but Luo Yu was far from complacent.

As the space fissures grew larger, and the cultivation levels of those who could pass through increased… a full-scale invasion by the Siwu Clan was inevitable!

Once that day came, even if he exhausted all his strength, even at the cost of his life, he would be unable to prevent Earth's occupation and humanity's destruction!

Therefore, he had long since made preparations, establishing the Forbidden City in the Vast Domain to grow humanity's forces — all to protect Earth and humanity better.

Yet Luo Yu hadn't expected that the Siwu Clan's bloodlust towards Earth would surge so strongly, abandoning all other battlefronts to lead an army directly to Earth!

To stop them, he fought two Martial Emperor-level Siwu Clan beings single-handedly.

The Forbidden City's entire forces also fought desperately outside the space fissure, intercepting the invading Siwu Clan army!

They intercepted them outside the fissure because if the enemies entered Earth, even killing them would be meaningless.

However, during the battle, Luo Yu noticed that one Fourth-tier Martial King-level Siwu Clan sneaked through and entered Earth.

He dared not delay even a moment, immediately burning his blood essence to severely wound and repel the two Martial Emperors and the invading army!

Then he compressed his own power level down to Fourth-tier Martial King and rushed back to Earth.

What he didn't expect was that the Fourth-tier Martial King-level Siwu Clan did not cause a massacre on Earth…

Instead, he was actually intercepted by a mere Peak Martial Commander-level youth!

Moreover, he was forced to the point of burning his blood to dig out his inner potential just to fight back!

Yet even so, he still couldn't suppress that Peak Martial Commander!

"This little guy… is really strong!"

Luo Yu's eyes sparkled.
