Two things broke the afternoon’s routine.

The first: the second-generation mutant maggot pupae had completed their development. Six blowflies, each roughly the size of an infant’s fist, were bouncing around the interior of the glass enclosure with the particular aggressive energy of something that had just discovered it could fly.

He ran their Level readings. 0.037 to 0.039 — marginally above Variant 1, consistent with the ambient-exposure mutation pathway producing slightly stronger results than the acute-toxin pathway. Both had developed the same Activity core type: the needle proboscis. He designated them Second-Generation Blowflies and logged the comparison.

The research design was complete. Variant 1: first-generation, induced mutation via peach toxin. Second-generation: offspring of unmodified flies, raised on Activity-rich substrate from hatching. Both had developed Activity cores. The second-generation specimens showed marginally higher Levels. That was the data point he’d been building toward since Chapter 31.

He set one of the larger second-generation specimens aside with a portion of the remaining Bull Demon King meat for continued observation. The other five went into a single enclosure.

Will the same-clutch second-generation specimens cannibalize each other?

The question had practical implications for whether the ant larvae would require isolation, but mostly he was curious. He gave them a week.

After that: fishing bait.

He was done maintaining a blowfly colony in an enclosed metal vehicle. The smell had become a permanent occupant of the cargo section’s atmosphere, and his tolerance for it had reached its limit.

The second event was considerably more complicated.

The ant eggs had hatched.

Two larvae, each slightly smaller than a mineral water bottle — so, roughly the size of the ant queen’s egg when mature — were moving around the transparent plastic incubation container. Pale, translucent bodies covered in fine cilia, the characteristic internal organ mass visible as a dark concentration in the center of each one. When Shen Cong approached, both larvae immediately oriented toward him and began moving in his direction.

The Activity communication came through unmistakably: recognition, approach behavior, something that felt distressingly like the response of a young animal to the presence that had been feeding it.

He stood there looking at two maggot-sized insect larvae trying to crawl toward him with every indication of enthusiasm and felt his expression go flat.

This is not acceptable.

He pushed a feeling of rejection through the Active connection — not forcefully, more like the mental equivalent of a closed door.

Both larvae stopped immediately and retreated to the far end of the container.

He stared at them for a moment.

That worked.

He crossed his arms and thought about the implications.

Establishing an Active bond with insect larvae was, on the spectrum of things he’d done since the apocalypse, objectively one of the stranger ones. Having those insect larvae respond to his emotional states through the bond was stranger still. But a bond that allowed directional behavioral control — that was a different category of capability than a bond that was merely mutual awareness.

What can they actually understand?

“Come here.”

They came.

“Go away.”

They went.

“Go to the corner.”

They went.

“Roll over.”

They didn’t. A confused feeling came back through the bond — the concept not translating, or the motor capability not existing to execute it, or both.

Fair enough. They’re larvae.

“Move your body back and forth.”

Same confused response. He tried several variations on the same concept. Nothing. The command vocabulary had limits.

After a few minutes, both larvae transmitted the same simple signal simultaneously.

Hungry.

He found a piece of Veggie Willow leaf and dropped it in. They ignored it completely.

He tried a sliver of raw bull meat. They approached, tasted it, and moved away.

He tried a piece of raw fish. Same result.

He looked at the two larvae sitting in their container, apparently uninterested in everything he’d offered, and remembered what he’d observed about the Short-sting ant colony: they’d been consuming metal. Every wreck in the car graveyard, methodically disassembled and eaten.

It can’t be that simple.

He dropped a scrap of waste iron into the container.

Scritch. Scritch. Scritch.

Both larvae went for it immediately, the mouthparts producing a sound he hadn’t expected — a fine rasping, like something abrading a surface. Looking closely, he could see the structure: a ring of sharp cutting edges around the mouth opening, capable of scraping material from a hard surface and ingesting the fragments. The iron scrap disappeared in slightly over three minutes.

He stood up and looked at the pile of waste iron he’d accumulated for trap construction.

I have plenty of that.

He tipped a substantial portion into the container. The larvae ate continuously for the rest of the afternoon while he worked on the traps, their bodies expanding visibly as they processed the metal, the translucent skin shifting through stages from pale white to pale yellow as the internal concentration of iron increased.

By the time he stopped for the evening, both larvae had reached the size of a large Coca-Cola bottle and had stopped eating. Their color had stabilized at a deep yellow-brown. Each had consumed roughly two and a half kilograms of metal.

Then they began moving toward each other.

He watched, unsure what to expect.

Not combat. The movement was deliberate but not aggressive — the two larvae pressing their bodies against each other, rubbing the full length of their surfaces together in a slow, rhythmic motion.

Molting.

He recognized the behavior once he’d seen it clearly. Many insect larvae molted by rubbing against another surface to help break and shed the old cuticle. Using each other as the rubbing surface was an adaptation he hadn’t expected from captive insects, but it made sense if they didn’t have a suitable rough surface in the container.

The shed cuticle was dark brown. The new cuticle underneath was — predictably — pale and translucent again, the second-instar body fresh and newly reset.

He ran the Level reading.

0.036 before molting. 0.048 after.

A 33% increase in a single day, driven by metal consumption and the physiological transformation of the molt. He noted the figure and then noticed something else: the Active bond felt different. Clearer. More information coming through in both directions.

The second-instar larvae had more sophisticated internal communication than the first-instar. Either higher cognitive development, or a better-developed Active sensory system, or both.

He decided to test the upper limit of the behavioral vocabulary.

“Roll over.”

The second instar larvae both paused.

Then —
