Summoning the Gods: Start by creating the Eternal Night.

Blood Demon Ancestor's body was surrounded by churning blood mist, and that terrifying suction force was like an invisible giant hand, forcibly drawing out the essence and blood of every cultivator present.

"No--!"

A cultivator at the Void Realm screamed as his body visibly withered away, his skin wrinkling like the bark of a dead tree.

The abundant spiritual energy instantly dissipated, and within a few breaths, it turned into a dried-up corpse, lying stiffly on the ground.

The number of cultivators in the stone chamber dwindled, those below the Void Realm were long dead, and even the Void Realm cultivators could not resist the domineering suction force and collapsed one after another.

As the essence blood continued to flow into his body, the Blood Demon Ancestor's aura rose at an astonishing speed, and the blood mist around him faintly emitted the sound of a dragon's roar.

"Celestial Realm! This demon has actually recovered to the early stage of the Celestial Realm!"

Yao Xing felt the overwhelming pressure, and his face turned ashen.

The loss of toxins and essence in his body has greatly reduced his strength, and he is now even unsteady on his feet.

Master Wufa, Daoxuan, Lingshan, and the others were in no better shape, all suffering serious injuries.

He could barely circulate his spiritual energy to resist the suction, and blood kept spilling from the corner of his mouth.

The entire stone chamber trembled violently, as if it would be torn apart at any moment by the aura of the Blood Demon Ancestor.

"We can't let him absorb any more!"

Yang Guo let out a low shout, exchanged a glance with Zhang Wuji, and at the same time unleashed all his power.

The Xuan Tie Heavy Sword in Yang Guo's hand emitted a hum, and a faint golden flame wrapped around its blade—a phenomenon caused by him pushing his internal energy to its limit.

"Break the Boundary!"

With a long roar, he swept his heavy sword horizontally, and a sword aura containing the intent of destruction tore through the sky. Wherever it passed, the blood mist was annihilated inch by inch, and it went straight for the Blood Demon Ancestor.

Zhang Wuji then formed hand seals, perfectly blending the Nine Yang Divine Skill with Tai Chi.

A dazzling ball of light rose from his palm, circulating the yin and yang energies and radiating a boundless, ever-renewing power.

"Nine Yang Breaks the Demon!"

The ball of light flew out of his hand, transforming into a giant golden dragon that roared as it charged toward the Blood Demon Ancestor.

"Overestimating yourself!"

The Blood Demon Ancestor snorted coldly. He had already entered the Celestial Realm and was full of confidence. With a wave of his hand, several blood-red giant pythons rushed out to meet the sword energy and the golden dragon.

"Boom! Boom!"

The sword energy clashed with the giant python, the golden dragon and the blood python became entangled, and the entire stone chamber erupted with an even more terrifying energy shock.

The combined forces of Yang Guo and Zhang Wuji actually managed to suppress the Blood Demon Ancestor's attack!

"How is that possible?!"

The Blood Demon Ancestor's expression changed drastically. He hadn't expected that these two young people could unleash such combat power and even suppress him, who had just recovered to the Celestial Realm!

With a determined heart, he suddenly increased the suction force, forcibly extracting the essence and blood of the remaining cultivators. Even Nirvana Realm experts like Yao Xing were forced to have their blood and qi surge due to this suction force, and almost collapsed.

"ah--!"

Four injured early-stage Nirvana cultivators could not withstand the draining of their life essence and blood, turning into dried corpses.

The Blood Demon Ancestor's aura surged once again, instantly breaking through to the mid-stage of the Celestial Realm!

"Not good!" Yang Guo and Zhang Wuji's hearts sank, as they felt the opponent's aura suddenly increase several times, and the original suppressive force was instantly reversed.

"Pfft! Pfft!"

The crimson python shattered the sword energy and the golden dragon, and with its remaining momentum, it crashed into the two of them.

Yang Guo and Zhang Wuji were struck as if by a heavy blow, flying backward and crashing heavily into the stone wall, spitting out a mouthful of blood and suffering minor injuries.

They fell to the ground and rolled right next to the Black King.

At this moment, all the Void Realm cultivators in the stone chamber had perished, leaving only Qingguo and Qingcheng barely holding on thanks to their treasures.

The Nirvana Realm experts from several major forces were also exhausted and could only watch helplessly as the Blood Demon Ancestor wreaked havoc.

Just then, Zhang Wuji's gaze suddenly fell on the Black Emperor, who was squatting in the corner.

Its mouth was bulging, and there was some red powder on the corner of its mouth. Its little eyes were darting around, clearly indicating that it hadn't done anything good.

Then he suddenly spoke to the Black Emperor:

"Black Emperor, didn't you say you were very powerful and could help us settle this? Now's your chance."

Black King was taken aback, looking at him warily: "What do you want to do?...

Before it could finish speaking, Zhang Wuji reached out and picked it up.

"Hey! Human, let go of me!" The Black Emperor struggled in his arms, kicking his limbs wildly.

Zhang Wuji, carrying the Black Emperor sword, walked to the front and called out:

"Brother Yang, you're stunningly beautiful! The Black Emperor is about to make his move; he says he'll handle this demon!"

"It said it was too powerful and might affect us, so it told us to stay away!"

"What the hell?!" Black Emperor roared, "When did I ever say such a thing?!"

Zhang Wuji ignored the Black Emperor and flung it directly in front of the Blood Demon Ancestor.

"Get out of here!"

Yang Guo exchanged a glance with Qingguo and Qingcheng. Although they were full of doubts, they had no better solution at the moment and could only follow their advice and retreat to observe from a distance.

The Black Emperor twisted in mid-air and landed steadily on the ground. He looked at the Blood Demon Ancestor, then at Yang Guo and the others in the distance.

A flicker of helplessness and anger flashed in his eyes. Now that things had come to this, there was no other way but to take action.

It shouted at Yang Guo and the others, "It's a deal! I'll help you deal with this old demon, and in return, you have to take me out of this broken secret realm and help me regain my strength!"

"Okay!" Zhang Wuji quickly replied.

The Blood Demon Ancestor stared in surprise at the little black dog being thrown over, then burst into laughter:

"Hahaha... What is this? You actually want to send a beast to deal with your ancestor? What a joke!"

As soon as he finished speaking, the Black Emperor's body began to undergo astonishing changes!

"roar--!"

A deafening roar erupted from its mouth, and its body, originally only a foot long, expanded wildly.

Its jet-black skin was covered with dense barbs, two huge black horns sprouted from its head, and its eyes shone with golden light like the sun and moon.

In the blink of an eye, it transformed into an ancient ferocious beast ten zhang tall, with two horns on its head and two wings on its back.

He exuded a terrifying aura that looked down upon the world, his head reaching the sky and his feet firmly planted on the ground, his aura was several times stronger than that of the Blood Demon Ancestor!

This is no longer an inconspicuous little black cat; it is clearly a ferocious beast!

Yang Guo and Zhang Wuji exchanged a glance, both seeing disbelief in each other's eyes.

Yao Xing, Dao Xuan, and the others gaped in astonishment, forgetting the pain they were enduring.

They simply couldn't imagine that this black dog possessed such a terrifying true form.

"What...what kind of monster is this?!" The Blood Demon Ancestor stared at the colossal beast before him, his face showing fear for the first time.

"An ancient species?! Impossible! How could such a being appear here?!"

The Black Emperor hovered in mid-air, his gaze icy as he stared at the Blood Demon Ancestor, letting out a low roar:

"You ignorant little devil, how dare you be so insolent before me? Today I'll show you what true power is!"

It raised its giant claws and, with a world-destroying aura, slammed them down towards the Blood Demon Ancestor.

The Blood Demon Ancestor was shocked and hurriedly activated his blood mist to defend himself.

"Bang!"

The Blood Demon Ancestor was sent flying, crashing into the stone wall like a kite with a broken string, creating a loud bang and leaving a huge hole in the wall.

The entire stone chamber fell silent instantly; you could hear a pin drop.

Yang Guo, Zhang Wuji, Qingguo, Qingcheng, and the surviving Yao Xing, Master Wufa, and others.

They all stared at the Black Emperor in disbelief, their mouths agape enough to fit an egg.

The Blood Demon Ancestor, who was just moments ago so arrogant and left them helpless, was actually swatted away by this little black dog... no, this ancient ferocious beast above him with a single paw?

The contrast is too great!

Black King glanced at the hole that had been smashed open and curled his lip in disdain:

"Pathetic. If my cultivation hadn't been incomplete, that claw attack would have obliterated your soul."

"Boom boom boom..."

Just then, the secret realm could no longer withstand the energy exceeding that of the Celestial Realm, or perhaps the time for the secret realm was approaching, and it began to shake violently and collapse!

The Black Emperor immediately flew to Yang Guo and the others: "This place is no longer safe to stay in; the secret realm is beginning to collapse! Come on up, I'll take you to the exit!"

Upon hearing this, Yang Guo and the others immediately flew onto the Black Emperor's back, ready to leave!

Upon seeing this, Yao Xing, Master Wufa, Dao Xuan, Ling Shan, and others also shouted:

"Mythical Beast Senior, please! Take us with you!"

However, the Black Emperor ignored them completely and flew away with Yang Guo and the others!

No one knew that after they left, deep within the hole that had been smashed into the stone chamber...

A blood-red figure slowly rose to its feet, its eyes filled with resentment and fear:

"...I, the Blood Demon Ancestor, will remember this grudge!"
