Cultivation Realms (Based on Reverend Insanity)
Cultivation in the Gu World is based on the fusion of primitive essence with Gu to increase the level of a Gu master.  In the case of the protagonist, his Celestial Diagram allows him to mix this system with Qi cultivation techniques.
Here is the progression of cultivation realms that we will follow for the protagonist:
Apprentice of Master Gu (1st to 9th level)
Initial phase where Master Gu collects and learns to manipulate weak Gu.
Han Feng has already passed this phase and advanced to the Master Gu Realm.
Master Gu (Rank 1 to 5)
Each rank advancement increases the capacity for primitive essence and control over Gu.
Han Feng is currently Rank 1, but secretly cultivating.
He needs to evolve without drawing attention, concealing his progress.
Master Gu Immortal (Rank 6 to 9)
Transcend mortality and refine the immortal essence.
Han Feng can mix the power of Qi cultivation, creating a unique method.
Sovereign Venerable (Rank 10 - Demigod)
Few reach this level.  Example: Venerable Immortal Renegade.
In the future, Han Feng may reach that level and challenge the supreme powers.
Supreme Being (Below only the Dao)
Transcendent existences that touch the Supreme Dao.
Only legendary figures have reached this level.

The Heir of the Celestial Diagram

The faint glow of the chrysalis flickered in the darkness of the cave, pulsing in an irregular rhythm. Han Feng narrowed his eyes, analyzing the flow of energy around the mysterious Gu.

He could feel that something was missing. The chrysalis was not just dormant—it was on the brink of evolution, but it lacked a catalyst to fully awaken.

His gaze turned to the Nebulous Wolf, still lying beside the chrysalis. The animal breathed slowly, and Han Feng noticed that subtle threads of bluish Qi flowed from the beast to the Gu.

"So that's it..." the wolf is nurturing Gu.

But why would he do that? The mist wolves were not known for forming bonds with Gu insects.

Han Feng would need to find out the reason without being discovered.

Hidden in the shadows, he activated his perception to the maximum. The energy inside the chrysalis moved like a whirlwind, absorbing the wolf's Qi, but without completing its transformation.

This meant that the wolf's Qi was not enough.

The pulse of the Gu oscillated between two types of energy, one harmonic and the other chaotic. Han Feng felt a shiver upon noticing the similarity with his Dual Chaos Larva.

Wait... and if the catalyst is something that harmonizes this duality?

Connection with the Dual Chaos Larva

He closed his eyes and channeled a thread of Qi through his Dual Chaos Larva. The response was immediate—the mysterious Gu reacted!

The chrysalis shone brightly for a brief moment before returning to its normal state.

The Dual Chaos Larva was compatible with this Gu!

This explained why he was able to feel it so clearly from the beginning. The Gu was not just any random insect—he was part of something greater.

Steal the Gu immediately and try to refine it alone.

Wait and better understand the connection between the Nebulous Wolf and Gu.

The first option was risky. If Gu wasn't ready and tried to refine it forcefully, he could destroy it in the process. Moreover, the wolf would probably chase him.

The second option required patience, but it could reveal more secrets about Gu's evolution.

If he wanted to grow without attracting attention, he needed to act intelligently. He would study this connection and find a method to transform Gu without exposing his true power.

With that thought, he retreated into the shadows, silently observing the interaction between the wolf and the chrysalis, waiting for the right moment to act.
