Chapter 7: Adaptive Reconstruction

Twelve segments became nine.

Leon stopped trying to translate the language and translated the pictures instead.

The embryo probably meant birth, or rebirth, or reincarnation. The sleeping body suggested suspension. Two overlapping figures could mean possession, duplication, or a legal problem no court on Earth had prepared for. The cloud of points looked far too much like disassembly without any promise of reassembly.

The full-grown human outline inside a geometric shell was the only option that implied an adult body and containment.

It could also mean execution inside a box.

Seven segments left.

He selected it.

CONTINUITY METHOD 7: ADAPTIVE ADULT BIOLOGICAL RECONSTRUCTION.

"That could be worse," Leon said.

The first wave of pain demonstrated that it could also be very bad.

Every muscle in his body contracted at once. His spine arched against the restraints and the chamber went white, then came back in pieces — the black core, streams of symbols, his own hands shaking against the seat.

DESTINATION ATMOSPHERE ACQUIRED.

The machine was sampling air from a place he had not yet reached.

OXYGEN: ELEVATED. PARTICULATE LOAD: HIGH. BIOLOGICAL EXPOSURE: NONLOCAL.

ADAPTATION REQUIRED.

Cold entered his veins with no needle involved.

A transparent diagram of his own genome unfolded above him, millions of markers going past too fast to read. The machine was not designing him from imagination. It was comparing his existing biology against destination constraints, repairing damaged expression pathways, and selecting changes inside a range it classified as human-compatible.

GENOME DEVIATION LIMIT: 2.8%. SPECIES IDENTITY: HOMO SAPIENS — RETAINED.

REPRODUCTIVE COMPATIBILITY: RETAINED.

He would have laughed at the third line if his jaw had been taking instructions. Apparently even impossible non-human medical technology understood the priorities.

The pain moved out of the muscles and into the bones.

Pressure inside his femurs and his ribs, as though invisible machinery had taken hold of every mineral surface and begun rebuilding the load paths. It did not feel like cutting. It felt like calculation being performed on living material.

SKELETAL REMINERALISATION. JOINT GEOMETRY CORRECTION.

His old shoulder injury disappeared underneath something considerably deeper. The machine found a fracture in his left wrist from when he was nine, two damaged molars, scar tissue in one lung from an infection he barely remembered having, and a slight asymmetry in his pelvis. It treated each of them as a defect, unless identity preservation overruled it.

FACIAL IDENTITY: PROTECTED. NEURAL IDENTITY: PROTECTED.

DISTINCTIVE SUPERFICIAL MARKERS: PROTECTED.

The scar through his right eyebrow stayed.

He was absurdly, disproportionately grateful for it.

Then his body lengthened.

There is no elegant way to experience bones growing fourteen centimetres in a matter of seconds. His legs felt pulled through the floor. His shoulders broadened against the seat until the adaptive padding withdrew around them. Muscle fibres tore, multiplied and reattached according to ratios he could not read fast enough to argue with.

MYOSTATIN REGULATION: MODIFIED. CARDIOPULMONARY CAPACITY: INCREASED.

He tried to scream, and discovered the chamber had taken control of his breathing. Air went in, paused, and left on a rhythm considerably more efficient than panic. His heart rate came down from a hundred and eighty to eighty-six while the pain continued at full intensity, which was its own particular horror.

Somewhere in the middle of it a respiratory model was comparing modern atmospheric assumptions against the sample ahead. Elevated oxygen improves exertion and increases oxidative stress and fire risk. So the machine strengthened his antioxidant pathways rather than simply making his lungs bigger, and Leon, in the middle of the worst pain of his life, found that genuinely elegant.

IMMUNE RESPONSE RECONSTRUCTION. MUCOSAL BARRIERS ADAPTED.

PATHOGEN LIBRARY: INCOMPLETE.

That last line mattered more than any of the others.

The machine was not making him immune. It was broadening his defences using a partial sample of somewhere it had only briefly touched. Unknown infections could still kill him, and would not be impressed by his bone density.

It is not making me safe. It is making me plausible.

He held onto the distinction, because technical limitations were easier to think about than suffering.

TELOMERE STABILISATION: CONSERVATIVE. NEOPLASM SUPPRESSION: ENHANCED.

PROJECTED NATURAL LIFESPAN: 167–203 LOCAL YEARS.

Local years, Leon managed to think. Excellent. Even the lifespan has a footnote.

RECONSTRUCTION COMPLETE.

TRANSFER.

He came back in mud.

The first thing was weight — his own, wrong, arriving through limbs that ended several centimetres further away than his body had budgeted for. His left hand was under him and his elbow was in something soft and warm, and for four seconds he could not work out which way the ground was.

The second thing was heat. Not sunlight. The air itself, thick and close, at a temperature his skin read as bathwater.

The third thing was the air going into him.

It went in richer than any air he had ever breathed and his chest took it without asking his opinion, and one full breath cleared a headache he had been carrying since the third week of October.

Leon got a hand under himself and sat up.

There was no capsule. No chamber, no restraints, no eleven metres of Bavarian concrete. He was sitting in wet black mud between the roots of something enormous, in a green light that had been filtered so many times on the way down that it had stopped having a direction.

The cube lay against his chest on its cord. Eleven centimetres. Eight point eight kilograms. Warm.

A pale line surfaced on its face.

TEMPERATURE: 29.8 °C. HUMIDITY: 82%. CARBON DIOXIDE: 0.071%.

OXYGEN: 23.4%.

RESERVE ENERGY: 0.0000041%.

LOCAL DAY: 1.

Leon read the oxygen figure twice.

Earth’s atmosphere had run at twenty point nine percent for as long as anything with a spine had been measuring it. Twenty-three point four was not a rounding error, not a local pocket, and not survivable as a mistake. It was a different planet’s worth of difference, and the machine had sampled it before he arrived and rebuilt his lungs to meet it.

He put one hand flat in the mud and pushed himself upright, and went up much further than he expected to.

For a moment he simply stood, at a height he had never occupied, in air that did not belong to him, holding a cube containing a number with six zeros after the decimal point.

Then something roared.

A long way east, low and enormous, climbing into a harsh vibrating bellow before it stopped.

It was not a sound any mammal makes.
