The apocalypse had given Shen Cong a strong visual impression of the new world: sky very blue, ground very gray-yellow, mutated creature blood very red.
Green had been essentially absent.
Until now.
He raised the telescope and looked.
A tree. Full canopy, branches heavy with what looked like fruit — red fruit, the deep saturated red of ripe peaches. Growing alone on a low hillside slope, isolated, the only living thing in a landscape that had otherwise been scoured down to bare rock and mineral sediment.
A peach tree.
A tree.
There’s a tree.
He said nothing and drove toward it.
Ten minutes later, Vajra was parked at the base of the slope, less than a hundred meters from the tree. He didn’t get out immediately. A lone tree surviving in conditions that had killed everything else was inherently suspicious, and the telescope view had shown something else on the ground beneath it that he wanted to examine more carefully before approaching.
Several animal carcasses. Partially decomposed, the torsos open, bones exposed. He could make out what looked like a monkey, something that might have been a wild boar, what appeared to be the remains of a large snake.
All of them within a few meters of the trunk.
He watched for ten minutes. The leaves moved in the light wind. Nothing else stirred.
He loaded the slingshot and put steel balls into the carcasses and the tree trunk in sequence. Testing for reaction. There was none.
He suited up, armed up, and climbed down from Vajra.
Rather than approaching directly, he went around the slope and climbed to the ridgeline above — higher ground, full view of the surrounding terrain. The area was barren in every direction. Exposed limestone, the same white-gray that had flanked the 208 all morning, no loose sand or gravel to speak of. Whatever had let the peach tree survive, it wasn’t because anything had protected it — the rock had simply been too hard for the storm to strip away.
No movement anywhere. Terrain too hard for Burrowers. He descended toward the tree.
The smell of the carcasses hit him at thirty meters. He kept moving.
At the base of the trunk, he stopped and pressed the fang-knife against the bark.
Clang. Clang. Clang.
Not the dull thud of wood. Something harder, denser — the collision sound of metal against stone, or metal against metal. He tapped again in a different spot and got the same result.
He felt the bark with his palm.
Cold. Smooth. Activity radiation moving through it at a steady, quiet rate — not intense, but continuous, the way Vajra radiated when passive.
The tree mutated. Of course it mutated. Nothing survives here without mutating.
He ran his thumb along a leaf. The edge had the faint resistance of something harder than plant tissue, a quality he was starting to think of as the early signature of metallic transformation — the same quality he’d felt in Activity cores before they’d fully developed. He shook a branch and got a sound like wind through thin metal sheeting rather than rustling foliage.
Is this tree turning into metal?
Then he examined the fruit.
The peaches were the size of an infant’s head, uniformly deep red, hanging heavy. He pulled one free and held it.
No metallic quality in the flesh — that transformation seemed to be limited to the structural components of the tree. But the Activity radiation coming off the peach was a different matter entirely. Stronger than any Activity core he’d handled. Stronger than the queen ant’s chest plate. The sensation of holding it was almost uncomfortable, like holding something that was generating a low-frequency vibration just below the threshold of hearing.
He looked at the fruit in his hand. Then he looked at the carcasses.
He crouched over the monkey remains, covered his nose, and used the fang-knife to poke through the decomposed material.
Mutated monkey — he could tell from the altered proportions and the enlarged canine teeth that had the characteristic dark silver of Activity cores. But the Activity in the body itself was completely gone. Drained. Dead long enough for even the residual radiation to dissipate.
He levered the carcass over with the knife.
Beneath it, where the body had been lying, was a network of white filaments. Fine as thread, densely packed, threaded through the decomposing fur and into the soil beneath. He followed one strand with his eyes to where it disappeared into a rock crevice, then pulled out the entrenching tool and dug carefully.
The filament ran through the shallow soil layer, navigating around rock fragments, and connected to the peach tree’s root system.
The tree is feeding on the carcasses.
He turned over the other bodies. White filament networks beneath all of them, all connecting back to the same root structure. The tree had sent roots to every corpse within its reach.
The picture assembled itself quickly.
Fruit loaded with Activity — irresistible to any mutated creature that could sense Activity radiation. The creatures come to eat. The peaches kill them. The roots move in and extract whatever Activity and nutrients the bodies contain. The peaches that grow from that extracted energy are even richer, attracting the next generation of visitors.
An Activity-powered predator trap, disguised as a fruit tree.
He looked at the peach in his hand with a different kind of appreciation.
I absolutely cannot eat this.
The Activity density in the fruit was genuinely extraordinary — exactly what he needed, exactly what would accelerate Vajra’s recovery and his own development. And it was almost certainly lethally toxic to anything that consumed it. The evidence was on the ground around him.
He spent a moment being disappointed about this in a focused and practical way.
Then his thinking moved, the way it usually did when he hit an obstacle, toward what the thing could be used for.
He thought about the prehistoric crocodile. He thought about whatever had been chewing through rebar in the Carrefour basement, which he still hadn’t identified. He thought about the category of threats that were too large or too armored for his current weapons to reliably handle.
A peach that killed mutated animals with unknown-mechanism toxicity, thrown by someone with one and a half to two bulls of throwing strength, into an open wound made by an Activity-infused javelin —
That’s worth keeping.
He wasn’t going to eat them. He was going to harvest them, study them properly, and develop a delivery method.
He cut a branch section with the fang-knife. Dug up a root segment with the entrenching tool. Picked three peaches, handling them through his cut-resistant gloves. Loaded everything into the cargo section.
Research first. Applications after.
He found the cleanest piece of equipment available, sliced a thin section from one peach, and sealed it in a glass vial. Reached into the blowfly enclosure and transferred one fly to a second vial. Introduced the fruit fragment.
Then he sat back and watched.
Toxicity test, subject one. Begin.
