Deep within the fragmented neurons of Han, Fang Yuan found a memory buried in layers of trauma. It was a visual data-stream: Han, younger and dressed in robes of liquid silver, standing before this very obsidian wall.
"The Null-Point Engine," the memory-Han whispered. "It doesn't run on mana. It runs on Paradoxes. To activate the interface, one must present a logic that exists and doesn't exist simultaneously."
Yuan's eyes snapped open. He understood. The Council of Order didn't just break the machines; they imposed a "Fixed Law" upon them. But Han, in his genius, had built a back-door.
The Memory Fragments Revealed:
The Key: The "Interface Port" is a Bio-Mechanical Lock. It requires the DNA of an Architect, but more importantly, it requires a Negative-Energy Pulse.
The Weapon's Name: This wasn't just a relic; it was the "Aegis of the Void-Slayer" (رداء ذابح الفراغ)—a Rank 6 exoskeleton designed to delete the existence of anything it touches.
The Location of the Core: The port in front of him was just a "Sensor." The actual core—the heart of the machine—was hidden inside the Planetary Core itself.
"So, the entire planet of Iron-Grip is the casing for the weapon," Yuan thought, a dark, indigo realization washing over him. "And these slaves... their labor is actually generating the friction needed to keep the engine's cooling-system active."
Yuan placed his hand on the obsidian. He didn't use Han's broken DNA. Instead, he channeled a Null-Logic Paradox: A command that says 'Open' and 'Closed' at the same Planck-second.

The obsidian wall didn't slide open; it pixelated and vanished, revealing a silver suit of armor that looked like it was woven from the silk of a dead star.
