Arc 231Demon Cave War and Alchemy
Saine kept Mechanical Civilization's main forces out of the Demon Cave war while supplying equipment and analysis to profit from the conflict and obtain Rule Fragments. The Demon Cave Master's origin backlash reshaped Saine's plans for new Dimension Supreme Treasures, while dangerous experiments led him to prioritize Wall-E's consciousness continuity.
- Saine developed the Sinking Model, approved the Mechanical Angel Civilization branch, and learned from Locke that stable contact with the Material Star Realm required reaching the Lord of Dimension level.
- Saine named Little Tenth's unborn child Saelot Grant and created a specialized gestation environment for him.
- The Evil Spirit King attacked the Demon Cave Master, while Saine supplied the Stein Empire without committing Mechanical Civilization's main legion.
- Wuzhuo joined the Evil Spirit King, and Saine traded battlefield analysis for the Demon Cave Master's Rule Fragments as the Temple Lords reinforced the siege.
- Locke warned Saine that the attackers remained far from killing the Demon Cave Master, and Saine began designing the Ten Thousand Mechanical Law Ring, Dimension-Severing Cage, and Wall-E's transformation.
- Saine tested the Ten Thousand Mechanical Law Ring prototype and worked with the Despair Matriarch to develop the Dimension-Severing Cage's layered blockade.
- The Demon Cave Master sacrificed star sectors and civilizations to unleash an Origin backlash, injured his attackers, and retreated as his homeland civilizations turned against him.
- Saine revised his treasure designs against origin backlash and made Wall-E's existence continuity the highest constraint after simulated core modifications caused consciousness collapse and contamination.
