Ten minutes elapsed with the dual-core model running independently, no frequency acceleration from Shen Cong, no external intervention.

Vajra’s saturation: Level 0.561.

The horns’ surface continued its iridescent flow. The closed field lines cycled between them, stable and self-sustaining. No decay in the resonance. No accumulation toward failure. The Activity resonance field was operating exactly as the model had predicted.

He spent the full ten minutes in pure observation rather than analysis — looking for any sign of instability, any deviation from the stable pattern, any indication that the success was provisional rather than genuine.

There was none.

This is real.

He let himself feel the satisfaction of that for a moment.

He hadn’t set out to solve the Level progression problem with this research. The original goal had been to find more sophisticated applications for Activity cores — better weapons, improved armor integration. What he’d found instead was something considerably more significant: a mechanism for accelerating Vajra’s development that didn’t depend on finding rare high-Activity food sources or high-Level evolved beasts to absorb.

He ran the math.

At current ambient Activity concentration with the field running, Vajra was gaining approximately Level 0.001 per ten minutes. That scaled to:

Per hour: 0.006. Per day: 0.144.

Current saturation: Level 0.562. Distance to Level 1: 0.438.

Three days.

He sat with that number.

Three days from Level 0.562 to Level 1, if the field sustained and the ambient concentration held. For comparison, during the apocalypse storm — the highest ambient Activity concentration he’d experienced — Vajra had managed 0.03 per day. The resonance field was producing more than four times that rate in the current, much lower ambient environment.

He checked the Geiger counter.

13 microsieverts.

The apocalypse storm’s peak had been 5 microsieverts. The resonance field was generating a local Activity concentration two and a half times higher than the worst storm had produced, in an environment where ambient Activity had declined significantly from those early levels.

The physics of this made sense once he worked through it. The field wasn’t creating Activity — it was concentrating it. Every ambient Activity particle within the field’s influence radius was being pulled toward the resonance point, creating a local density far exceeding the surrounding average. The absorption rate scaled with local density, not ambient density. He’d been limited by the ambient concentration for weeks. The resonance field effectively uncoupled his development speed from that constraint.

Not impossible. Just unforeseen.

He drank some water, watched the field continue its steady work, and opened the laptop.

The experiment report took thirty minutes to complete properly.

At the end, he needed names for what he’d produced.

Activity Resonance Field — the closed field generated by resonating Activity cores. Simple, descriptive, accurate. Short form: Activity Field.

Resonance Liquid — the liquefied surface layer of Activity core material that forms when resonance conditions are met. Functions as the conductive medium for field propagation, analogous to the poles in a magnetic system.

Field-Force Storm — the vortex of concentrated ambient Activity generated by the field’s attractive force. Drawing from magnetic field terminology: field strength described the varying intensity at different points within a magnetic field; his Activity vortex showed the same distribution pattern.

The dual-core model itself needed a name.

Bull Horn Dual-Core Activity Resonance Field was accurate and completely unwieldy.

He thought about it while finishing the last of the edible bull meat.

Totems — the Warcraft III totem structures that Tauren shamans used to train and buff their units, radiating magical effects in an area around them, was what the image in his mind kept landing on. The bull horns generating a field that enhanced everything within its radius. A totem that strengthened its owner.

Bull Demon King Totem.

He named it after the creature he’d hunted, with a reference that fit the aesthetic precisely and that he suspected no one else would ever understand. That was fine. It didn’t need to make sense to anyone else.

Vajra, enveloped in the field-force storm of the Bull Demon King Totem, absorbed Activity continuously.

The Level counter ticked upward.

August 9th.

The daily surveillance check turned up nothing. Zhang Youhai’s group didn’t appear. The township was empty in both directions, the ruins silent under the late-summer morning light.

He returned to Vajra and turned his attention to housekeeping.

The Bull Demon King meat had been aging for several days now, and the last sections had crossed past the edge of safe consumption. He buried them beneath the roots of the large mutated willow at the lake’s edge — the tree he’d been eating leaves from for its vitamin and carotenoid content, the one that had managed to provide edible greens without the intestinal consequences the Man-eater Peach Tree’s leaves had produced.

He’d been calling it the Veggie Willow in his head. He made it official in the field guide.

Veggie Willow: mutated willow tree, evolved plant category. Bark shows clear metallic transformation. Branches resist breaking. No fruit production. Leaves edible — contain moderate Activity and useful quantities of vitamins and carotenoids. Root structure normal — no evidence of corpse-feeding filament networks.

Level 0.128 today, up from 0.127 a few days earlier. Slow but continuous development, same as everything else in this world.

He patted the bark where he’d placed the buried meat.

The willow was feeding Activity-rich organic material to its root system. In return, its leaves were providing him with the vegetable nutrition that had been entirely absent from his diet since the apocalypse. The relationship had a pleasant symmetry to it.

When the willow catkins finally come — if they come — I could use them for insulation.

He stood at the lakeside and let himself think something that wasn’t tactical or analytical or preparatory.

The world is still growing. Even now. Even here.

Then he went back to Vajra and watched the Totem work.
