Bold hypothesis, careful verification. That had been the principle since the beginning.

Accelerating Vajra’s Active frequency to uncontrolled speeds was an experiment with real failure modes. Vajra’s mass meant the vehicle itself would be fine regardless of what happened — but the human standing in the adjacent compartment was less guaranteed. Hence the Baogai Armor, the queen ant chest plate maintaining Active circulation through the whole suit. If something went wrong, he wanted that layer between himself and it.

He locked in his concentration and began.

Hum.

Vajra’s Active frequency climbed — higher than he’d taken it before, the sensation in the guidance connection shifting from the normal comfortable resonance into something more intense, more pressured. He directed the accelerating field toward the test core: a Short-sting worker ant mandible, Level 0.057, the smallest and most expendable Activity core he had.

The mandible began to change.

Not visibly at first — only through his extended perception, the Activity within the core starting to respond to the incoming frequency. Then visibly: the surface of the curved bone-analog structure showing the first signs of surface deformation, a slight yielding, something approaching the behavior of metal near its melting point.

He had approximately three seconds of satisfaction before the mandible exploded.

Not a dramatic explosion. More like a very fast structural failure — the core disintegrating into powder under the accumulated pressure, the released Activity dispersing outward in a pulse that swept through the cargo section.

The shockwave was mild. His lungs registered it. The Baogai Armor absorbed the rest.

When the dust settled and the Active pulse dissipated, he ran a saturation check.

Vajra had gained approximately Level 0.0001 from absorbing the released Activity in the pulse.

He brushed powder off the armor and looked at where the mandible had been.

That’s actually interesting.

The explosion was a failure of the primary objective. The side effect — a pulse of released Activity that Vajra could absorb — was an unintended discovery worth examining. He filed it and moved on.

Upgrade the test specimen.

Short-sting soldier ant mandible. Level 0.071. More robust than the worker variant.

Same procedure. Same result. Explosion, pulse, Level 0.0001 absorbed.

Again.

Burrower mandible. Level 0.101. Higher Activity concentration, presumably more resistant to resonant pressure.

Explosion. Pulse. Level 0.0001 absorbed.

Again.

Teddy Tyrant fang. Level 0.149.

Explosion. Pulse. Level 0.0001 absorbed.

He was burning through his Activity core collection. He acknowledged this and continued.

Tumour-Pig crescent tusk. Level 0.187.

This one hurt to sacrifice. The crescent tusks had been among his best cores — the curved shape, the exceptional radiation intensity, the material he’d been planning to work into weapons or armor upgrades. He looked at it for a moment, then decided that understanding the resonance phenomenon was worth more than preserving a weapon component he hadn’t found the right application for yet.

He set it in place.

The frequency acceleration began.

Hum. Hum. Hum.

This time, the core didn’t immediately fail. The surface began to show the same deformation signature as the previous specimens — but it held. The material softened, the Activity concentrated within beginning to flow across the surface rather than staying locked in its fixed distribution. And then something happened that none of the previous cores had produced:

The core’s own Activity frequency began to shift in response to Vajra’s incoming field.

Not randomly — matching it, orienting toward it, the two frequencies locking into a coupled oscillation. This was resonance. This was what he’d been looking for.

It’s actually working.

He held his concentration steady and increased the frequency slightly.

The crescent tusk’s surface fully liquefied — the Active material flowing and restructuring while maintaining the core’s fundamental integrity. And from that liquefied surface, a field began forming. An Active field, extending outward from the resonating core, building in radius as the resonance deepened.

The field reached the walls of the cargo section. Then extended beyond them.

And ambient Activity — the sparse free-floating particles that normally required patient absorption over hours — began converging toward the field. Not slowly. Quickly. The field was acting like a concentration gradient, a low-pressure system drawing in Activity from the surrounding environment, pulling it toward the resonating core and by extension toward Vajra.

Vajra began absorbing at a rate Shen Cong had never observed during ambient absorption.

This is what magnetic resonance does in physical systems. A magnetized material, under resonant conditions, absorbs energy from the surrounding field far more efficiently than it does normally.

He didn’t have time to finish the thought.

One minute and thirty seconds after resonance was established, the crescent tusk failed. The accumulated stress exceeded the core material’s capacity to sustain the resonant state. It detonated.

The resulting shockwave was considerably larger than the previous failures — a full minute and a half of resonance had been building energy in the system, and all of it released at once. The Active pulse swept through the cargo section and into the surrounding environment. Vajra absorbed the pulse, and absorbed the dispersing ambient Activity that had been concentrated in the field, and absorbed what it could of the wave as it passed.

Total gain from the morning’s experiments: approximately Level 0.001.

His own Level, through Exchange: 0.752 → 0.753.

He sat down and ate lunch without resuming the experiments.

The direction was clear. The crescent tusk had held resonance for ninety seconds before failing. The Bull Demon King horns were two full Level tiers above the crescent tusk. By the same scaling, they might sustain the resonance state long enough to produce significantly more ambient Activity absorption before the failure point — or, theoretically, they might not fail at all.

But might not fail was doing a lot of work in that sentence, and he’d just destroyed a significant portion of his best Activity core collection in the process of arriving at this understanding. The horns were Level 0.215, the single most valuable material he currently possessed. Using them in an experiment that had destroyed every lower-Level specimen so far, without a clearer model of the failure mechanism, was the kind of decision that required more thought than he’d yet given it.

He spent three hours after lunch working through what he’d observed.

The failure mode appeared to be a mismatch between the resonance energy input rate and the core material’s capacity to dissipate or integrate it. Every specimen had eventually accumulated more resonant energy than its structural integrity could sustain, at which point rapid catastrophic failure occurred. The crescent tusk had lasted longer not because it was fundamentally more stable but because it had a larger capacity before reaching the failure threshold.

The solution was either:

• Find a specimen with sufficient capacity to never reach the failure threshold under sustainable resonance conditions.
• Find a way to dissipate the accumulated resonant energy before it reached the failure threshold.
• Distribute the resonance across multiple cores simultaneously, reducing the load on any single specimen.

The third option had the most immediate practical appeal. He had a collection of Activity cores spanning multiple species and Level values. If he could establish resonance across several of them simultaneously, each one absorbing a fraction of the incoming energy, the collective capacity might exceed what any single core could handle alone.

He opened his notebook and started designing.

Multi-core resonance stabilized Activity field model.
