Cultivation of immortality begins with an eighty-year-old eunuch.

"Eunuch Chen, why don't you take a look inside and see what treasures are inside?" Eunuch Wei was so anxious that he scratched his head and cheeks.

"There are more important things to do now than magical artifacts."

Chen Fan's gaze was cold and piercing. He flipped his right hand, and a palm-sized, jet-black soul banner appeared in his palm.

It was none other than the Black Soul Banner, who had just recently advanced to the late stage of the Nascent Soul realm!

"Although the physical bodies of these old monsters are destroyed, the resentment and fragments of their souls that erupted before their deaths still linger in this world. If we don't collect them quickly, it would be a waste if they dissipate."

Chen Fan sneered and frantically poured the power of the fusion of immortals and demons within his body into the Black Soul Banner.

"Splash!"

The Black Soul Banner swelled in the wind, instantly growing to over three zhang tall. On its surface, a million living souls roared deafeningly, and a terrifying suction force swept across the entire Black Stone Plaza like a hurricane!

"receive!"

Chen Fan roared and formed a hand seal.

"Waaaaah..."

A mournful wail echoed across the square.

Four illusory figures were forcibly pulled out from various corners of the ruins.

It was the lingering soul of the Mysterious Bone Master, the Thousand Poison Old Woman, the Iron-Armored Corpse King, and the Ghost-Faced Scholar!

Although their physical bodies perished, their souls, even those at the half-step Void Refinement stage, were incredibly powerful. Even in their incomplete state, they still retained a strong sense of instinct.

"Ghostwood! You despicable villain! Give me back my life!" The remnant soul of the Armored Corpse King roared in resentment, trying to break free from the suction force.

"I curse you to die a horrible death!" The soul of the Thousand Poison Old Woman transformed into a cloud of poisonous mist, frantically crashing against the void.

"Noisy."

Chen Fan remained expressionless, his aura surging, and the pressure of the Freezing Word Technique directly pressed down on the four remnant souls, instantly immobilizing them.

"Swish, swish, swish!"

The four remnant souls were absorbed into the Black Soul Banner without any suspense.

However, just as Chen Fan was about to collect the soul of the Fire Source's true form, a sudden change occurred!

Suddenly, a blinding dark golden light burst forth from the corpse of the Fire Source, which was riddled with holes!

A miniature primordial spirit, extremely condensed and radiating pure Void Refinement pressure, actually broke free from the restraints of the Zhenyuan Nail and burst out of the corpse!

This primordial spirit looked exactly like the original Fire Source, only shrunk countless times. At this moment, it was staring intently at Chen Fan with eyes filled with endless resentment and madness.

"You little beast! You've ruined my three-thousand-year plan, and you even intend to grind my physical body to dust! Even if it costs me my soul and spirit, I will seize your body!"

The primordial spirit of the Fire Source True Body let out a shrill shriek, transforming into a dark golden lightning bolt that shot directly towards Chen Fan's sea of ​​consciousness between his brows!

He actually still retained the power for one last possession!

"Be careful, Eunuch Chen!" Eunuch Wei exclaimed in alarm.

"That's exactly what I've been waiting for!"

Chen Fan did not retreat even a step; instead, a chilling sneer curled at the corner of his mouth.

"Buzz!"

A strange gray-white rune suddenly appeared between his brows. The three concepts of cause and effect, life and death, and stillness merged perfectly at this moment, transforming into an indestructible mental barrier that stood firmly in front of his sea of ​​consciousness.

"Bang!"

The primordial spirit of the Fire Source True Body crashed heavily against the barrier, erupting in dazzling sparks. His already damaged primordial spirit dimmed instantly under the backlash from the three realms of intent.

"How is this possible! How could your spiritual power be so strong when you are just a late-stage Nascent Soul cultivator!" The Fire Source True Body let out a desperate wail. He finally realized that he had kicked an indestructible iron plate.

"Go inside!"

Chen Fan snorted coldly and suddenly thrust the Black Soul Banner in his hand forward!

"ah!!!"

With a heart-wrenching scream, the Fire Source's original spirit was completely swallowed by the endless black energy and forcibly pulled into the Black Soul Banner.

"Boom!"

As five powerful half-step and Void Refinement level souls entered his body, the Black Soul Banner trembled violently. On the banner's surface, a million living souls were forced into a corner by these five powerful old monster souls, trembling in fear.

"How domineering are these remnant souls! They actually want to turn the tables and devour the other living souls within the banner to strengthen themselves!" Eunuch Wei was horrified.

"Once it's in our hands, even a dragon has to coil up, and a tiger has to lie low!"

Chen Fan's hands moved swiftly, forming hand seals like butterflies flitting among flowers, and the pure power of the fusion of immortals and demons within his body poured into the Black Soul Banner without reservation.

"Seal the Immortal Demon Seal!"

With a low shout from Chen Fan, a complex rune of interwoven gold and black appeared on the Black Soul Banner, transforming into five indestructible chains that rushed directly into the banner, binding the souls of the five old monsters tightly and dragging them into the deepest part of the Black Soul Banner, where they were completely suppressed!

"call……"

After doing all this, a fine layer of sweat appeared on Chen Fan's forehead.

"Eunuch Chen, is that all?" Eunuch Wei stepped forward, looking curiously at the Black Soul Banner that had returned to calm.

"It's just a temporary seal." Chen Fan shook his head, his tone grave. "These five souls are too powerful, especially the Fire Source's original spirit, the Void Refining Primordial Spirit. Even in its incomplete state, it's not something I can forcibly refine right now. Forcibly refining it would only cause a backlash and destroy the Black Soul Banner. I can only seal them within the banner for now. Only when my cultivation breaks through to the Great Perfection of the Nascent Soul stage, or when I find higher-grade materials to reforge the Black Soul Banner, can I completely subdue them."

"However," Chen Fan's tone shifted, a glint of light flashing in his eyes, "once they are completely refined, the power of this Black Soul Banner will definitely reach the half-step Void Refinement level, or even the true Void Refinement level!"

After carefully putting away the Black Soul Banner, Chen Fan lifted his robe and sat cross-legged on the steps of the altar.

He laid out the five storage bags in his arms in a row in front of him.

"Now, let's get down to business."

A genuine smile finally appeared on Chen Fan's lips. All that painstaking effort and meticulous planning—wasn't it all for this moment?

He was the first to pick up the storage bags of the four half-step Void Refinement old monsters.

As the divine sense forcibly erased the remaining spiritual imprint on it, the items in the storage bag tumbled to the ground.

"Oh dear, so poor! These four old beggars, and they're supposed to be half-step Void Refinement cultivators!" Eunuch Wei rummaged through the things on the ground, looking disgusted.

Indeed, as Eunuch Wei said, the storage bags of these four old monsters were unusually shabby.

Aside from the mountains of top-grade spirit stones, numbering in the millions, there wasn't a single trace of rare and precious materials, pills, or elixirs.

"That's not surprising." Chen Fan said calmly, picking up a dull jade slip. "They've been trapped in this forbidden zone for thousands of years without any outside resources. To survive and to break through to the next level, they must have used up everything they had that they could eat and use. Even many of their magical treasures probably exploded or were destroyed in the fierce battle just now."
