An emperor in his later years is summoned by his sister to save the nation's fate.

The moment Lu Li made his move, the black aura of the Emperor's Banner in his hand surged.

The fierce souls of several quasi-emperors, including Tianxuan Quasi-Emperor, Zifu Quasi-Emperor, and Xiao Zhantian, roared out and transformed into a black demon god that blotted out the sky, directly pressing Yama Heavenly Venerable, who was trying to escape to the side of the Underworld Emperor, firmly into the void.

"Great Emperor, save us..."

The sound effect of Yama, the Heavenly Lord of Hell, crying for help got stuck in his throat.

"Sizzle—!"

Dozens of pitch-black soul-binding chains pierced through his head at the same time.

The divine soul of Yama, a quasi-emperor at the peak of the ninth level, was forcibly pulled out of his Niwan Palace without any suspense and instantly absorbed into the Human Emperor Banner.

His pure blood and energy were instantly drained by the Devouring Heaven Demon Art net that lit up in Lu Li's palm, turning him into a withered corpse that fell into the void.

After doing all this, Lu Li slowly turned around and placed his double pupils, which emitted a faint chaotic light, on the gloomy-faced Underworld Emperor.

"The Seven Killings Sect, was it you who single-handedly built it up?"

Lu Li stroked the Taiyin Immortal-Slaying Blade, his tone calm, but the killing intent within it made the temperature of the entire cave world drop to freezing point: "So, in that case, you, the Underworld Emperor, are also partly responsible for the cause and effect behind their repeated assassination attempts on me back then."

Upon hearing this, the Hades' lifeless eyes gradually turned cold.

Who is he? He is the Underworld Emperor who has intimidated the Eastern Wilderness for tens of thousands of years! Within this forbidden zone of the Underworld, he has the advantage of terrain, and even the current emperor, whose life force is at its peak, has to show him respect.

Because anyone who fights against him must constantly face the possibility of being deprived of their chance of survival.

Emperors are often beings who cherish their lives, and none of them are willing to waste their precious lifespan in the underworld for no reason.

"Eternal Night, I acknowledge that you have lived a second life, and the vigor of your life far exceeds my expectations."

The Underworld Emperor spoke indifferently: "But do you think that with your peak vitality you can do whatever you want in this Underworld? I will make you understand that this place will become the grave you regret stepping into for the most in your life!"

Just as the Underworld Emperor was about to launch his attack, the Great Dao runes within Lu Li's double pupils circulated rapidly.

His gaze, which disregarded all spatial barriers, instantly pierced through the layers of restrictions underground and located the secret chamber where Tianjizi was imprisoned.

Before he could begin the purge, he had to save Tianjizi's life.

"A universe hidden in the sleeve!"

Lu Li remained calm and composed, gently waving his long black sleeves.

"Buzz—!"

A sudden burst of spatial overlap laws caused the entire secret chamber where Tianjizi was located, along with the foundation and restrictions covering hundreds of feet in radius, to be forcibly stripped away and shrunk into a speck of dust with a single wave of his hand. This speck of dust instantly flew into Lu Li's wide sleeve space, thus avoiding the impact of the upcoming battle between emperors.

Upon seeing Lu Li's unfathomable spatial abilities, the Underworld Emperor's eyelids twitched slightly, but he didn't pay much attention to it.

"In the face of death, any struggle is meaningless and futile."

The Underworld Emperor snorted coldly and clasped his hands together.

"Splash—"

An ancient book, entirely black and radiating a chilling aura and the energy of the Great Dao of Death, appeared out of thin air before him.

The black book cover is engraved with a tragic relief depicting countless evil spirits devouring and all souls perishing.

This is the Netherworld Emperor's natal imperial weapon, the Netherworld Emperor's Death Mystic Book, which he has been refining for tens of thousands of years!

This imperial weapon has only one function: to forcibly deprive all living beings of their vitality.

As long as the Underworld Emperor uses his own Dao of Death as a pen, he can write the target's true name, or their imperial title or honorific known to the world, on the blank pages of this Book of Death.

The Law of Death will ignore space and forcibly drain and assimilate the life force within its body!

The Hades Emperor's withered fingers flew through the air, writing rapidly, and lines of imperial script formed from black death energy slowly emerged on the Death Mystic Book.

It was none other than—the Eternal Night Demon Emperor!

"Buzz—!"

As the characters were formed, the Netherworld Emperor's Book of Death erupted with a jet-black light.

The Great Dao of Death trembled violently, and the entire void of the cave was filled with overwhelming death energy, which descended upon Lu Li, attempting to forcibly extract all the life force from his body!

Looking at the black death aura surrounding him, Lu Li revealed a mocking smile.

"Deprive me of life? Underworld Emperor, do you really believe that my Dao injuries have not healed, and my vital energy is still as depleted as it was back then?"

"Today, I, the Emperor, will show you what true immortality and eternal life are!"

As Lu Li took a step forward, the Great Perfection Ancient Sacred Body within his body finally revived with a roar!

"Boom!"

The raging golden blood energy, like thousands of dragons roaring at the same time, surged into the sky from every pore of Lu Li's body, directly washing away and dissolving the death energy falling around him!

Immediately afterwards, Lu Li activated the extraordinary phenomenon of the Holy Body's origin with a thought.

The Celestial King descends upon the Nine Heavens!

Behind Lu Li, the void violently tore apart, and a phantom of a Celestial King, thousands of feet in size and radiating dazzling white light and primordial purple energy, suddenly appeared.

The illusory image of the immortal king had a blurred yet majestic face, wore a nine-tassel crown, and was dressed in spotless white robes.

Beneath its feet, the phantom of the Nine Heavens slowly emerged, with countless dazzling stars revolving around it.

The illusory image of the Celestial King sat cross-legged high in the heavens, only a beam of celestial light emanating from him.

Under the blessing of this supreme phenomenon, the surging vitality of Lu Li's Great Perfection Sacred Body, which was like a vast ocean, was enhanced to a state that was almost indestructible!

"Sizzle sizzle..."

The death energy released by the Netherworld Emperor's Death Mystic Book, which was enough to exhaust the lifespan of an ordinary emperor, did not have any effect of stripping away life force when it collided with this golden blood energy and the clear light of the Immortal King. Instead, it was like cold water being poured into boiling lava, producing a piercing melting sound, and instantly dissipated completely!

"What?"

A barely suppressed look of horror finally erupted in the Hades Emperor's lifeless eyes, and he exclaimed in disbelief, "Ancient Sacred Body? And a fully-fledged Ancient Sacred Body at that? How is this possible?!"

As an existence that has attained enlightenment through the path of death, his only nemesis is the monstrous physique of a person who has achieved physical sainthood and whose vitality is so vigorous that it cannot be measured by common sense!

And the Ancient Sacred Body is the strongest among them!

The Great Perfection Ancient Sacred Body possesses a life essence that is practically equivalent to a self-circulating life star field. To forcibly strip it of its vitality with death energy is tantamount to trying to scoop up an endless sea of ​​blood with a spoon!

Not only did it fail to deprive him of his life, but the next moment, a sudden, unbearable roar came from the Emperor Weapon, the Netherworld Emperor's Death Mystic Book.

A powerful backlash surged back along the law channel, directly striking the Underworld Emperor's body.

"puff--!"

The Underworld Emperor's face turned deathly pale instantly, and he spat out a mouthful of dark, supreme blood essence. The decaying supreme aura around his body also dimmed considerably, indicating that he had suffered considerable injury from the backlash.
