The entire universe erupted into turmoil!
Before this, although Haotian the Great Emperor had traversed the six Forbidden Zones and even struck out forcefully, he had always stopped short of a true battle.
Even in Immortal Mountain, if the Undying Daoist had not come out on his own, there most likely would not have been an earth-shaking battle.
Thus, in the eyes of many, Haotian the Great Emperor had merely been displaying his might while taking the opportunity to plunder the Forbidden Zones.
When Haotian the Great Emperor arrived at the Underworld, everyone thought he would act as he had before.
No one had expected that Haotian the Great Emperor had not come to plunder the Underworld.
Haotian the Great Emperor had come to kill!
That was right! Ying Hao had indeed come to kill!
After their ancestor, the Sun Human Emperor, passed away, the Underworld Supreme had set his sights on their lineage in order to refine the Sun bloodline.
Aside from the Source God, whom he had slain back then, the Underworld Supreme Yuan Gui had also made a move.
Blood debts had to be repaid with blood. This battle was unavoidable!
"Junior, you're being far too arrogant. Do you really think you can become a Supreme's enemy?"
As the cold voice rang out, the Underworld Supreme Yuan Gui walked out of the Underworld and looked at Ying Hao with eyes brimming with killing intent.
Yuan Gui regretted that he had not acted in time back then, allowing the person before him to grow into an unprecedented enemy.
"There's no need for threats. I came here only for revenge!"
Ying Hao stood atop the void. Emperor Qi surged ten thousand zhang around him, making space tremble and rumble as terrifying pressure spread throughout the universe.
Yuan Gui had appeared, and Ying Hao could not be bothered to waste more words. He struck out with one palm, and a great sun slowly rose, hanging high in the heavens.
"Junior, you're going too far! Do you really think suppressing the Undying Daoist made you invincible under heaven?"
Yuan Gui's voice was cold and emotionless. He knew that Ying Hao's killing intent was resolute, and that there was no longer any possibility of avoiding this battle.
Yuan Gui roared. His entire body was covered in blood-colored fur, savage and terrifying, like a vicious ghost, as he struck out forcefully.
Boom!
Amid the tremendous rumble, terrifying powers intertwined. Yuan Gui's palm exploded, and blood dripped down.
Yuan Gui's expression turned livid. He had witnessed the battle between Haotian the Great Emperor and the Undying Daoist and knew that Haotian the Great Emperor's strength was extraordinary.
However, although the Undying Daoist was a Supreme, he was not an Ancient Emperor and had never possessed an era of invincibility under heaven.
For that reason, even after the Undying Daoist underwent Ultimate Ascension, his strength was actually somewhat weaker than theirs.
Yet only after truly exchanging blows with Haotian the Great Emperor did Yuan Gui understand just how terrifying this person was.
He was so powerful that it was unreasonable. He did not look like a Great Emperor who had entered his twilight years; instead, he seemed to be at the peak of his prime.
Yuan Gui was shocked and furious. He fought back with all his strength, but that great sun continued pressing down unwaveringly.
"Ah!"
As a shriek rang out, blood splashed thirty thousand feet into the air. Yuan Gui's entire arm broke inch by inch, and blood poured down like rain.
The True Sun Fire clung to him like maggots on the bones, and boundless agony filled his entire body, but Yuan Gui could no longer care about it.
He had already been locked onto by Haotian the Great Emperor's Dao. The great sun was pressing down on him—this was meant to take his life!
The Imperial Dao Law swept across the entire universe. The Heavenly Dao and the myriad Daos wailed, and Yuan Gui underwent Ultimate Ascension!
If he could, he naturally would not have wanted to undergo Ultimate Ascension. But if he did not, he would die.
After undergoing Ultimate Ascension and returning to his peak, he became a flawless Ancient Emperor. He would then be invincible beneath the heavens!
Ying Hao and Yuan Gui unleashed their killing moves at the same time. Terrifying power intertwined, and tens of thousands of zhang of chaos drowned everything.
All living beings in the universe were terrified. Another divine battle erupted, even more violent than the previous one.
"Are you still not making your move?"
Yuan Gui suddenly roared and rapidly retreated, tearing through the void as he arrived at the edge of the universe in an instant.
Yuan Gui panted heavily. The blood constantly dripping from his body made it clear how much pressure he had endured in the previous battle.
Ying Hao's expression was cold as he pursued relentlessly. The moment he stepped into the edge of the universe, dazzling Immortal Light appeared.
It was a treasure wheel wreathed in Immortal Light. It tore through the vast universe and emerged, its entire body black yet crystalline.
"Nether Venerate's Heaven-Piercing Underworld Treasure!" Ying Hao said calmly.
The treasure wheel shone brilliantly. Surging rays of light flowed like water, while billions of auspicious radiances rose into the air, making the void tremble.
This was Cao Yusheng's Ultimate Emperor Weapon from the past. After enduring the tempering of time, it had become even more extraordinary and had already developed a spirit.
Beneath the Heaven-Piercing Underworld Treasure stood a monster covered in long fur. Demonic energy surged around him, making him resemble Yuan Gui.
"Haotian the Great Emperor truly has extraordinary insight, but you will definitely die today! Remember my name. I am Source Demon!"
Source Demon looked down upon the world. His aura was extraordinary as he sneered at Ying Hao, his eyes revealing intense killing intent.
When Source Demon appeared with the Heaven-Piercing Underworld Treasure, Yuan Gui breathed a sigh of relief, but his heart was filled with even greater hatred.
According to their original plan, he would draw Haotian the Great Emperor's attention while Source Demon suddenly attacked with the Heaven-Piercing Underworld Treasure.
The plan had been flawless. It was highly likely that Haotian the Great Emperor would be slain before he even had the chance to consume the Immortal Medicine.
However, they had misjudged Haotian the Great Emperor's strength. Shortly after exchanging blows, Yuan Gui had already been forced to undergo Ultimate Ascension.
He looked toward Haotian the Great Emperor, his eyes filled with greed. He wanted to live, and Haotian the Great Emperor was his only chance.
With such extraordinary qualities, and with a Great Emperor in his twilight years still possessing such battle prowess, Haotian the Great Emperor should be able to extend his life.
"Big words! I am the Great Emperor of the Human Race. Why should I fear insignificant wretches like you?"
Ying Hao's expression was cold. Facing two Supremes, he advanced instead of retreating, tearing through the void as he moved forward, as forceful as ever.
He extended his hand. Five Elements Power gathered, and five-colored radiance shot into the sky before pressing forward.
Green, yellow, red, black, and white appeared. Moving at an inconceivable speed, they pressed down simultaneously toward Source God and Yuan Gui.
Source God and Yuan Gui were instantly horrified. Feeling an aura that made them tremble, they hurriedly joined forces to offer up the Heaven-Piercing Underworld Treasure.
The Nether Venerate's Emperor Weapon slowly rotated, revealing a scene of the Underworld as it pressed down toward Ye Fan, manifesting tens of thousands of great Dao symbols.
This star region instantly became like a swamp, obstructing Ying Hao's advance. Various Dao runes flickered, possessing unmatched power.
Ying Hao was completely unafraid. Five Elements Power surged wildly from his five organs, and five-colored radiance shone dazzlingly.
Boom!
An earth-shaking collision erupted in an instant. Terrifying power raged through the void, completely drowning out the figures of the three.
Ying Hao's bearing was solemn as he stared at the Heaven-Piercing Underworld Treasure. This Emperor Weapon of the Nether Venerate was indeed extraordinary.
Ever since he had used Lingbao Heavenly Venerate's Five Elements essence to cultivate the divine ability Five-Colored Divine Light, he had diligently practiced it all these years.
The divine ability Five-Colored Divine Light had long since become vastly different from before, yet it was still blocked by the Heaven-Piercing Underworld Treasure.
After years of refinement by the Underworld Supremes, this Emperor Weapon was now likely not far from becoming an Immortal Artifact.
At the same time, Yuan Gui and Source God exchanged a glance, and both could see the deep shock in each other's eyes.
The Heaven-Piercing Underworld Treasure was their ultimate weapon prepared for Haotian the Great Emperor. Yet after a single collision, it had already begun to totter?
If this continued, once the Heaven-Piercing Underworld Treasure could no longer hold, would they not have to face Haotian the Great Emperor directly?
Suddenly, Source God and Yuan Gui's expressions changed drastically once more, as though they had seen something inconceivable.
