The sky was still overcast. No sun.

For the first time in a month, Shen Cong set foot on solid ground — and found that the ground he remembered was gone. Yellow sand, broken rock, and gray dust stretched in every direction. Not a single patch of green anywhere. It looked less like Anhui Province and more like the edge of a desert that went on forever.

Home. Wuwei. Hefei’s probably gone too.

He stood there for a moment, scanning the wasteland, looking for any sign that something had survived. The storm had scoured the land clean. The only proof that this was still Earth — and not somewhere else entirely — was the handful of steel load-bearing columns standing alone in the distance, exactly where the warehouse used to be. One of them was bent at a perfect ninety degrees.

Shen Cong pushed down the bleakness rising in his chest and walked over to where the warehouse floor had been. He looked around for a moment, then crouched and tried to dig through the sand and gravel with his hands. Too slow. He jogged back to Vajra, grabbed an entrenching tool, and came back swinging.

His body after a month of the Vajra link was something else. He worked through the sand at a pace that would’ve left the old him doubled over and gasping. Now he barely broke a sweat.

Before long, he’d opened up a substantial pit.

The Activity really does enhance my body. I would’ve been wrecked doing this a month ago. Now I don’t even feel it.

The Activity — that was the name he’d come up with for it himself. The strange ability. The reason he and Vajra were connected.

When he’d come around after blacking out on the day of the meteor strike, he’d noticed the link almost immediately — a vague, persistent sense of the truck’s condition bleeding into his own awareness. Over the following month, locked inside with nowhere to go and nothing but time, he’d probed at it constantly. Testing, experimenting, reasoning through what he felt. By now, he had a rough working theory.

The meteor that hit the warehouse should have left a crater. At meteor-impact energy levels, the shockwave alone should have obliterated everything in the immediate area — including Vajra, and Shen Cong inside it. Instead, the warehouse was gone but the ground was almost undisturbed. Whatever that meteor was made of, it wasn’t ordinary rock.

It had carried something. Some kind of energy.

And that energy had done something to Vajra’s metal — something Shen Cong could only describe as waking it up. He didn’t know whether Vajra was truly alive in any meaningful sense. But the truck had unmistakably developed a kind of awareness, and it was using that awareness to slowly repair its own damage. That quality — that aliveness in the metal — was what he called the Activity.

When the meteor first hit, Vajra had been badly damaged. Large sections of the outer armor had melted. Internal wiring had burned out in multiple places. But when Shen Cong quieted his mind and focused on the connection, he found he could guide the Activity — nudge it into drawing in ambient energy from the surrounding environment and using it to patch the damage, slowly but steadily. He could also direct it to make limited physical changes to Vajra’s structure according to his will.

He’d named that function Extension.

The Activity had two other functions as well.

The first was Amalgamation — the ability to absorb and integrate. When the meteor hit, only Vajra’s metal frame had been infused with the Activity. But guided by Shen Cong, the Activity could expand outward, consuming the various components attached to the frame — electronics, mechanisms, anything — drawing them into itself and making them part of one unified whole. The reverse was also true: remove a component from Vajra, and within a short time, the Activity in it would fade and die.

The second was Exchange — the feedback loop between Vajra and Shen Cong. When he poured his focus into Vajra’s various systems, reinforcing his will through each part of the vehicle, the connection deepened. He could operate Vajra directly through his own brainwaves, without touching the controls. And in return, the Activity flowed back into him — gradually, consistently strengthening his body.

Active metal. Three properties: Extension, Amalgamation, Exchange.

That was a month’s worth of research, distilled.

There were almost certainly more properties he hadn’t uncovered yet. And plenty of questions he still couldn’t answer. The most fundamental one being: what exactly was the relationship between him and Vajra? By any normal logic, a vehicle infused with a mysterious life-giving energy should either evolve into some kind of autonomous transformer or just slump into a large, inert blob. The fact that it had instead formed a symbiotic bond with its driver — treating Shen Cong’s mind as its own — wasn’t something he could explain.

Not that I’m complaining. A stronger Vajra means better odds of surviving whatever this world has turned into.

The pit was deep enough now. At the bottom was a steel plate.

This was the hidden entrance to the underground room beneath the old warehouse. Shen Cong’s persecution complex had never let him feel safe without layers of redundancy, so the majority of his most important supplies and equipment had been stored down there, behind a steel barrier. That steel plate had done its job — the underground room was intact.

The shelves and workbenches inside were in a mess — toppled and scattered across the full 150 square meters, clearly rattled by the meteor’s shockwave. But most of it was still usable.

For the next three days, Shen Cong shuttled back and forth between Vajra and the underground room. He wasn’t in a rush to leave yet.

Vajra had taken serious damage. A month of passively absorbing ambient Activity had helped, but the recovery was slow by nature — the Activity couldn’t simply reshape matter at will. Some components needed to be physically replaced before they could be drawn into Vajra through Amalgamation and properly integrated.

In whatever spare time he had, he also got the truck’s radio set back online and started scanning frequencies for any sign of life.

Every channel returned the same thing: static.

When he needed a break, he climbed up to the roof of the truck and looked out. Sand in every direction, all the way to the horizon. The world was completely silent. No dogs. No insects. Just wind and emptiness and him.

Another week passed.

By the end of it, Vajra was fully restored. Every piece of equipment had been drawn through Amalgamation and made part of the whole.

The truck still ran on diesel — but part of the power supply now ran off a battery bank, and Shen Cong had installed two solar panels to supplement it when fuel ran low. It wasn’t a great solution. With a full tank, the three engines ran at full capability. But once the diesel was gone, he’d be down to battery power alone — enough to run a single motor at reduced speed, pushing Vajra forward at roughly jogging pace. Every two hours of travel would need a solar recharge cycle.

He’d had no choice. Fuel took up too much space to stockpile more than what he already had.

Vajra’s fully operational. Time to move.

His mechanical watch read June 28th. Shen Cong lowered the steel plate back over the underground room entrance and shoveled the sand back in to cover it. Before sealing it, he left one thing inside: a longwave transmitter, set to a frequency only he knew. If he ever needed to find his way back, he’d be able to home in on it.

Out here now, with sand covering everything in every direction, there was no other way to mark a location.

This place was his roots. He wasn’t willing to lose even that.

He picked up the welding torch one last time.

On the remaining steel columns — the only structures still standing — he burned a message into the metal:

Tune to FM 90.8 — Survivor Shen Cong — I have left.

That done, he took one last look at the columns.

Then he climbed up into Vajra.

Armor sealed. Radar raised. Throttle down.

The engines roared to life. A thin ribbon of exhaust curled up from the pipe extending above the cab. The steel battle rig — its armor reshaped by Shen Cong’s guided Activity into a smoother, spike-studded shell, its chassis raised, its wheels widened to handle broken terrain — rolled forward, pressing deep tracks into the sand and gravel, and headed north.

Toward Wuwei.

Toward what used to be home.

A moment later, a gust of wind moved across the plain. Sand lifted and swirled and resettled. When it was done, the tire tracks were gone.

If not for those few columns still standing their quiet vigil, the place could have been a desert from the beginning of time.
