He secured the bunker. Now he has to rule the zone.

Jake Mercer survived the system reboot. He turned a cold war bunker into a Sanctuary, leveled up his [Admin] class, and forged a powerful Affinity Network with his team. But in New Harbor, standing still is a death sentence.

Phase 2 has begun: Expansion.

The city is fracturing. A chaotic entity known as the "Glitch King" is tearing holes in reality, rewriting the laws of physics to turn the streets into a twisted playground. Worse, General Stone isn't done; he's preparing a "Mana-Cascade Bomb" to wipe Jake's sector off the map permanently.

To counter a threat this massive, Jake needs more than just clever hacks—he needs an army. Or at least, a High Elf.

Deep in the corrupted subway tunnels, Jake recovers a new asset: Serara Moonwhisper, a displaced Elven Mage with the power to turn the tide. But adding her to the team pushes the Affinity Network to its breaking point.

The bond has evolved into a Local Area Network (LAN). Now, Jake, Nina, and Daphne don't just share mana—they share everything. Sensations, desires, and pain bleed across the link in real-time, turning every tactical maneuver into an intimate, high-stakes feedback loop.

Jake must master his new [Zone Architect] powers to turn his bunker into a fortress. He has to hack the Glitch King, defy the Paragon army, and keep his Cluster from burning out in the process.

The tutorial is over. It's time to conquer the map.

Network Node continues the Level Up Hero series—a cyberpunk LitRPG adventure featuring base building, reality-bending admin powers, and a complex, spicy harem dynamic that powers the very system itself.
