Spirit and Flesh Unite

Lin Fei did all this for one purpose.

To avenge his master!

Since he could not rely on the Mystic Heart Sect, he could only create a force of his own.

Whether it took a hundred years or a thousand years.

Even if it took ten thousand years.

He would achieve this goal. Only by completely uprooting the Earth Dragon Sect could he face his master with a clear conscience.

This Phantom Demon Jellyfish possessed mid-stage Spirit Transformation Realm cultivation.

Its consciousness had long since been erased, leaving behind only its primordial spirit.

"If I had not returned to the Mystic Heart Sect this time and become an elder of the Alchemy Hall, I would not have had the chance to access the method and formula for refining Spirit Transformation Pills."

"However, the Mystic Heart Sect possesses very few pill formulas above fifth-grade Heaven rank. If I want to refine higher-grade pills in the future, I will have to find another way."

"But for now, as long as I can refine Spirit Transformation Pills, that will be enough."

After extracting the medicinal ingredients one by one, Lin Fei began fusing their medicinal power with the Phantom Demon Jellyfish's primordial spirit.

As the medicinal power continuously merged, the Phantom Demon Jellyfish's primordial spirit seemed to come alive again.

It continuously released power, battering against the Azure Flame Furnace.

It wanted to break free from this prison.

Lin Fei's pressure immediately surged. This was no less difficult than confronting the Phantom Demon Jellyfish directly.

With his current late-stage Nascent Soul Realm cultivation, even with the Azure Flame Furnace—now promoted to a mid-grade spirit artifact—suppressing it, he still felt immense pressure.

"The power of this Phantom Demon Jellyfish's primordial spirit, after absorbing the medicinal power, is no weaker than when it was alive."
