Purgatory Sulfur Plane, Incense Divinity Path central control room.
As the last crystal panel inlaid with intricate runes was fitted into the recess of the main control array, Benjamin carefully completed the calibration of the final energy circuit.
He stepped back two paces and activated the full diagnostic program.
Hum...
The entire central control room lit up with a soft milky-white glow. Countless fine energy patterns flowed across the walls, floor, and ceiling as though they had come alive.
Dozens of light screens floating in midair lit up at once, massive streams of data rapidly refreshing across them—Power of Faith collection efficiency, Spirit Energy conversion rate, energy network node stability, real-time status of the Black Giant population...
Three minutes later, every screen switched to a pleasing green, and a gentle synthesized voice sounded. "Incense Power Collection Network Module, Thought Resonance Array installation complete. Full system self-diagnostic passed. Estimated operational efficiency increase: 37.2%."
Benjamin let out a long breath and rubbed his slightly aching brow.
The installation work for this final section had been far more complicated than expected.
It had originally been planned for completion within half a year, yet it had been dragged out for nearly two years.
Most of that time had been spent resolving the compatibility issues between the "Thought Resonance" and "Faith Purification" subsystems.
Still, they had made it in time.

As special elemental lifeforms personally created by Benjamin and refined through multiple rounds of improvement, the Black Giants possessed physiological traits completely unlike those of ordinary creatures.
They did not need food or sleep, their metabolism was extremely slow, and their lifespans were long.
Even the most ordinary Black Giant
