The week at Cedar Grove produced what it was supposed to produce.
He slept past dawn twice, which had not happened in approximately two years. Isolde ran the full-spectrum analysis on the Sovereign Catalyst crystals using the estate laboratory's equipment, which took three days and produced a research document she sent to the restricted archive with the notation that the alchemical community would need approximately a decade to properly respond to the implications. The herb specimens from the Cinder-Wilds border sector were processed and catalogued across two mornings with his assistance, the conversation that accompanied them running through the secondary metabolite classifications and the specific ways that high-mana-density soil altered the compounds he was already familiar with from the standard cultivation sources.
Sloane showed him the NOVUS archive of the dungeon footage.
He had, in fact, watched the Iron-Root Glade footage three times.
He acknowledged this when pressed.
By the final day, the specific fatigue from the dungeon sequence had cleared, the channel recovery confirmed through the standard checks, and the mana reserves were stable at the level they'd been before the Tier 5 runs.
He said his goodbyes in the specific way goodbyes at Cedar Grove happened: Isolde held on slightly longer than the duration that was technically required, and Sloane's grip on his shoulder conveyed what it always conveyed, and the car back to the capital felt like crossing a threshold in the direction it was harder to cross.
He went back.
The Palace's Tier 5 sector became his next structure.
Not because it was the limit of what was available — the Tier 6 access was still cleared — but because the comprehension work at 90% needed a specific kind of sustained engagement rather than the one-off high-intensity encounters the Mirror-Lord and the Mother-Seed had provided. Sustained high-density spatial law application in a genuinely hostile environment, over extended periods, was the pressure that moved the comprehension incrementally rather than in threshold-crossing events.
He established a daily rhythm: the Searing Basin in the morning, when his channels were clearest and the volcanic environment's thermal pressure required constant domain maintenance rather than periodic high-output response. The Gale-Glass Desert in the afternoon, which required a different form of spatial precision — the Prism-back population had regenerated sufficiently to provide active engagement, and the optical environment required the domain to manage coordinate accuracy rather than simply thermal suppression.
Nagini had developed her own rhythm within this structure, moving through the dungeon populations in the specific way a Level 50 spatial law entity moved through Tier 5 threats: not combat, logistics. She was running her own cultivation work, the beast cores she absorbed across each session producing the slow continuous growth that her status had been tracking since the Tier 7 Silverback.
The comprehension readings moved.
[Law of Space: 91%]
The 91% threshold did not announce itself the way 70% and 90% had announced themselves. It was a quieter shift — the spatial sense's resolution increasing in the specific way that was becoming familiar, the coordinate map of whatever environment he occupied becoming more present rather than simply more detailed. The difference between 90% and 91% was not dramatic from the inside. It was the difference between a very precise instrument and a slightly more precise one, where the precision was already well past what the ordinary world required.
The Facility Commander had, by the fourth day, moved past his initial professional shock into a different relationship with the daily deposit of Tier 5 haul material. He stopped asking which dungeon each day. He simply processed the intake and updated the facility's reserves documentation.
On the seventh day he issued the access to the Imperial Family's Private Collection, which was the facility's mechanism for acknowledging that a practitioner had contributed to the war chest at a level that warranted something in return.
The collection was held in a vault adjacent to the equipment storage, maintained at the conditions appropriate for Tier 6 artifact storage. He spent forty minutes reviewing the inventory with the specific attention of someone who was not looking for impressive-sounding items but for things with properties relevant to the dungeon work he was actually doing.
The Aegis of Eternity was at the vault's third section.
The material was immediately identifiable through the spatial sense's read: woven from a compound substance that existed at a phase state between conventional matter and spatial law material, the specific property of which was that it didn't fully occupy the coordinate space it appeared to occupy, existing slightly out of registration with the physical plane. The practical result was that elemental forces — thermal, kinetic, electrical — encountered the cloak's coordinate space and found it less coherent than the expected target, reducing their effective transfer by approximately 80% at current measurement.
It had no visual distinction. It looked like a dark cloak. The spatial sense made it considerably more interesting.
He put it on.
The weight settled with the authority of something that had been constructed for exactly the conditions he was working in.
[Law of Space: 92%]
The comprehension continued to move.
The Iron-Root Glade's second and third visits, in the weeks following the Cedar Grove return, had developed into the specific project that the first visit's analysis had suggested was possible.
The initial run had been destruction of the Mother-Seed to collapse the network. The second run he had been testing the boundary between how close he could bring the Mother-Seed to failure without crossing it — the specific point where the network's central node was sufficiently compromised to remove its threat without being destroyed entirely.
It was a finer-grained spatial law problem than the combat work. The Mother-Seed's architecture was an active, responsive system that adapted to the pressure he was applying. Bringing it to the precise threshold he needed — functional structure intact, parasitic directional bias removed, the repair-cycle architecture preserved — required the kind of coordinate precision that the comprehension increases were directly enabling.
By the third visit, he could bring it out intact.
Not completely intact — the process still required the Cinder-Root refinement and the spatial law boundary assertion that he and Isolde had developed in the border city apartment. But the raw material entering that process was now the complete node rather than the fragments. The difference in yield was substantial.
He sent the first complete-node crystal to Isolde via the Cedar Grove laboratory's secure receipt protocol.
Her response came back the same evening.
The output matches your projection. Three crystals from the fragment yielded measurable ambient generation. The complete node has produced eleven. The architecture is fully intact — none of the degradation I expected from extraction stress. Sending the extended analysis to the restricted archive under the original classification. — I.A.B.
P.S. Are you sleeping.
He sent a reply confirming that he was sleeping appropriately.
He was sleeping approximately appropriately.
The Commander flagged him at the end of the third week.
Not with concern — with the expression of someone who had been watching a supply chain develop and had arrived at a logistical observation.
"The Iron-Root Glade's boss regeneration cycle," he said. "Standard reset is forty-eight hours. You've been running it every sixty hours. You're staying just inside the reset window but maximising the time the core architecture has to consolidate before the next extraction."
"Yes," Markus said.
"You're farming the dungeon," the Commander said. Not accusatory. The observation of someone who had managed dungeon access for a long time and had not previously encountered this particular operational approach.
"The material has research applications that justify the extraction rate," Markus said. "The Aurelian Alchemy Institute has the relevant documentation."
"I'm not objecting," the Commander said. "I'm noting that the facility's Glade sector is currently providing the most significant alchemical material output of any sector in the complex, and the output is coming from one practitioner running the boss encounter solo every sixty hours, wearing a cloak that makes the environmental hazards largely irrelevant." He looked at the intake log. "This is going in my quarterly report."
"What notation," Markus asked.
"'Anomalous efficiency,'" the Commander said. "I'll file it under resource optimisation."
"Accurate," Markus said.
He went through the portal.
The Iron-Root Glade received him with the specific quality it had developed across three extractions: not unfamiliarly, the way a place developed a quality when you had been in it enough times to recognise it and it had been shaped enough times by the things you had done in it to carry them.
He moved through it with the Aegis reducing the thermal-botanical pressure to manageable, the spatial sense running its coordinate map, the domain maintaining the extraction window.
92% spatial law comprehension.
Eight percentage points remaining.
He went to work.
