No tires. No instrument panel. No seat. No mirrors. No lights front or rear. The fuel tank had several holes rusted through it.

That was the motorcycle — what remained of it, anyway.

Except for one thing: mounted at the rear, apparently welded on at some point before everything fell apart, was a small iron cage. Completely intact. Not a scratch on it.

Shen Cong looked back and forth between the cage and the Plastic Rabbit, suppressing the devour-instinct that flared up every time his attention settled on the frame, and started piecing together a narrative.

Before the apocalypse hit, the motorcycle’s owner was on their way somewhere — probably to sell the rabbit. They saw the meteors coming down and ran. The rabbit couldn’t run. It was in the cage.

So it went through the same process Shen Cong did. The motorcycle woke up. The rabbit and the motorcycle formed a bond.

Whatever happened between then and now was complicated. Both of them survived — the storm, the flood, two months of a dead world. The rabbit didn’t know how to use Activity consciously, so the motorcycle absorbed ambient energy and repaired itself on its own, slowly, over time. When the flood came, the high ground kept them above water.

Eventually the rabbit left to find food — maybe following the Activity signal, which is how it ended up at Vajra, which is how Shen Cong caught it. With regular meals and a warm cage, it forgot about the motorcycle for a while. Then the Teddy Tyrant and Tumour-Pig moved into the territory — possibly drawn by the motorcycle’s Activity radiation, possibly trying to claim it — and the rabbit went berserk trying to get back.

And that’s how today happened.

The story had holes in it. Why had all those vehicles concentrated in this particular area? What had the rabbit been eating for two months? Why hadn’t the apocalypse storm killed something with essentially zero protection? Why did the corrosion intensity increase the closer you got to the center of the pile?

He couldn’t answer those questions. But the broad outline felt right.

More importantly, seeing the motorcycle had connected several things in his mind that had been sitting unconnected for weeks.

Every mutated creature he’d catalogued had an Activity core — a dense, metallic structure where the energy concentrated most intensely.

He didn’t have one. The Plastic Rabbit apparently didn’t have one either.

But he had Vajra, and the rabbit had the motorcycle.

We’re not outside the Activity core framework. We’re just a different configuration of it. The question is whether Vajra is my core, or I’m Vajra’s core.

He sat with that for a moment.

Either way, in practical terms, he was the one directing everything. His willpower was the operating principle of the whole system. Whether he was the core or the shell didn’t change who was in control.

Still — knowing the answer would let him develop the Activity more precisely. And the Activity core was clearly the central mechanism of mutation, the engine that drove everything else. Understanding it was the highest-priority research item he had.

Beyond the research question, there was a larger choice implied by all of it.

The meteor shower had changed the world. The Activity was real and it was everywhere. That left exactly two options: find a way to reverse it, to cure the changes and restore the old baseline — or accept it, work with it, use it deliberately to become something the old world couldn’t have produced.

He knew which one he wanted.

He’d watched his parents die in a car accident when he was fifteen — gone in an instant, so fast there was no time to react, no time to do anything. For seven years that moment had been the fixed point his life orbited around. The paranoia, the isolation, the six years of building Vajra — all of it was some version of I will never be that helpless again.

Now there was a path that led somewhere beyond helplessness entirely.

He just had to reach for it.

He took a long breath and pulled the larger thoughts back down.

Wanting something too badly was how you made mistakes. He’d learned that. He let himself want it, noted the wanting, and set it aside for now.

Back to the immediate question.

Which is the Activity core — the rabbit or the motorcycle?

The devour-instinct only activated around the motorcycle frame, not the rabbit. That suggested the motorcycle was the source. Which would mean, by extension, that Vajra was the source in his own case — and he was the extension, the shell, the guided expression of Vajra’s Activity.

He reached his hand toward the motorcycle frame and tried to absorb its Activity directly, the way he absorbed ambient energy from the environment.

Nothing happened.

His body had never been able to pull Activity from external sources on its own — it only came through food or through the Exchange link with Vajra. So direct absorption wasn’t available.

Two other options remained.

He could cook and eat the Plastic Rabbit, and see if that produced results.

Or he could guide Vajra to absorb the motorcycle’s Activity directly.

If eating the rabbit was the mechanism, the devour-instinct would have pointed at the rabbit, not the motorcycle. The instinct knows what it wants.

He focused, extended his willpower into Vajra’s systems, and reached toward the motorcycle.

Through the enhanced perception the Vajra link provided — the expanded sensory range that came from eighty-five percent of a large vehicle being saturated with Activity — he got his first clear view of what the motorcycle actually was.

A fireball.

Not literally, but in Activity terms: a concentrated sphere of energy, radiating outward at an intensity he’d never perceived before, pulling ambient Activity toward itself continuously, glowing in his extended sense like something that had been burning quietly for two months in the dark.

The devour-instinct surged. He stopped thinking about whether he should and just did it.

Vajra’s systems swept toward the fireball like water finding a drain.

On first contact, a large portion of the motorcycle’s Activity transferred in a single pulse — absorbed into Vajra’s frame, fed immediately back through Exchange, flooding Shen Cong’s body with a warmth that was almost electric.

This is what devour means.

The difference in absorption speed was not subtle. Compared to pulling ambient Activity from the surrounding environment — slow, patient, measured — this was like the difference between drinking from a cup and opening a valve. Faster by orders of magnitude.

He did it again.

咕咕. 咕咕. 咕咕.

The Plastic Rabbit detonated.

It threw itself against every surface of the cage simultaneously, all the composure of the last few days gone, blood-matted eyes fixed on Shen Cong with an expression that — if he was interpreting animal body language correctly — combined terror and pure rage in roughly equal measure.

He glanced at it briefly and kept going.

Each pulse of absorption sent a wave of feedback through the Exchange link — not just warmth now, but something that resonated at a deeper level, the kind of physical sensation that made him understand why people used the word soul even when they didn’t believe in it. Muscles, skin, internal organs — everything sharpening simultaneously, the Activity density in his body climbing toward levels he hadn’t approached before.

The motorcycle’s fireball was dimming visibly with each pass. The rabbit’s screaming was losing force.

On the sixth absorption, Vajra sent back something he could only describe as saturation — a fullness, a sense of having taken in as much as the system could process at once. A hard stop.

He let go of the connection.

And immediately noticed that he was on fire.

Not literally — but close enough to matter. His mouth had gone completely dry. His face felt like he’d pressed it against something hot. He could feel his core temperature rising in a way that had nothing to do with the ambient temperature in the cargo section.

He moved fast.

Three bottles of mineral water, back to back, drunk standing up. It helped. Barely.

He looked down at his arms and watched steam rising off his skin.

His hand against his forehead: forty-five degrees, at minimum.

He grabbed a full water jug, sat down on the floor, and pressed his face against the cool plastic.

If I’d done one more cycle, I might have actually caught fire.

Ten minutes of deliberate cooling before his temperature came down to something that felt survivable. He sat on the floor and let his heart rate normalize and tried to think clearly about what had just happened.

The absorption was real. The speed advantage was real. The upper limit on single-session intake was also very real, and he’d found it the hard way.

He stood up, wiped his face, and looked at the cage.

The Plastic Rabbit was flat on the floor of the cage. Not moving. Breathing shallowly.

The motorcycle frame, which had been gleaming silver-white under its surface rust layer, had gone gray. Dull, flat, lightless.

He checked the rabbit’s pulse and respiration.

Alive. Unconscious.

He looked at the motorcycle frame for a long moment.

Then he pulled out the laptop and opened a new entry in the research log.
