Chapter 315

At six in the morning, the sky just began to lighten, and dew still hung on the grass blades outside the camp tent. Ah Ming, the eldest of the triplets, squatted in front of the folding table, snapping the last printed filter component into the plastic housing with a click. He wiped sweat from his forehead, looked up, and shouted at the tent: "Done! Module one is assembled; we just need to load it onto the vehicle."

Second Brother Liang crawled out of the sleeping bag, hair messy like a bird's nest, toothbrush clenched in his mouth as he walked out: 'Is there early Meal Ticket? I'm so hungry my front belly sticks to my back.'

No time for meals, Third Sister Ah Ling kicked open the toolbox beside her foot, picked up her backpack and began inventorying supplies: 'Those kids east of the village had diarrhea again last night; we need to set up the water purification device before the sun dries the road.'

Su Qing came over from the neighboring tent holding the water quality tester, still clutching the freshly printed lab report. She hadn't relaxed her brow, and she slapped the paper on the table: 'The upstream water sample has iron levels four times over the limit, copper also high—not natural seepage. This water is undrinkable; we need to deploy the system quickly.'

A Ming stepped over to look at the data, while twisting open the material slot of the 3D printer to change consumables: 'The original plan won't work; the large equipment is stuck midway and can't pass. We need to switch to modular deployment, using bamboo charcoal plus sand and gravel as the base, embedding biofilm, and connecting in sections.'

'Do we have enough manpower?' A Liang finally finished brushing, spat out the foam, and casually grabbed a bottle of water to rinse his mouth—only to have A Ling slap it away.

'You're still drinking water? This water isn't even fit for rinsing!'

'I, I just want to wet it a bit...'

'Even wetting it counts!' A Ling glared, 'Each person is limited to one bottle per day; don't even think about taking an extra drop.'

Su Qing ignored their bickering, already opened the Tablet to pull up the map: 'The transport team says a mudslide has blocked the main road; the heavy platform will be at least twelve hours late. We can only rely on manpower to carry components uphill. The water storage tank is on the mountaintop, eight hundred meters away, steep slope, dense forest—at most we can carry two modules per trip.'

'Then we'll make more trips.' A Ming closed the printer lid, patted the machine: 'As long as it keeps running, it's fine. A Liang handles material resupply, A Ling leads the transport team, and I'll go to the site to assist installation.'

'Wait a minute,' A Liang pulled out the spare battery from his backpack: 'This printer has been running nonstop under the African sun for three days; the cooling fan is about to burn out—if we don't let it rest a bit, it'll really go on strike.'

'Even if they strike, they have to hold out until this afternoon.' Su Qing glanced at her watch: 'Those kids can't wait. We'll first deliver the five portable units over there, let the villagers take turns fetching water, and later build fixed points.'

Before her words finished, a commotion came from afar. Several barefoot African children ran into the camp, the leading little girl holding up a broken plastic bottle, chattering in the local language. A Ling caught the key words, her face changing: 'She says the stream behind the village has turned red, is bubbling, and smells foul.'

Su Qing immediately grabbed the sampling bottle and gloves: 'Lead the way.'

Half an hour later, the group passed through the dense forest and arrived at a once-clear stream. Now the surface showed a rusty sheen, oil-film-like scum floated on it, and the stones along the bank were stained dark red. Su Qing crouched, took a mid-layer water sample with a long-handled spoon, then pulled out a portable probe to measure pH.

'Strong acidity, mixed heavy‑metal pollution.' She frowned, 'It doesn't look like a geological cause; it's more like industrial discharge.'

A Ming pointed to a concealed rock crevice upstream: 'There's movement there—sounds like water flow—but the map doesn't mark a stream.'

They pushed aside the vines and found behind the rock wall a concealed, artificially built channel, its bottom constantly discharging reddish‑brown wastewater that followed the natural slope straight downstream. A Liang launched a drone for aerial footage; minutes later it returned images: deep in the forest lay an abandoned mine shaft, surrounded by barbed wire, with armed guards patrolling the watchtowers, the insignia on the flags indistinct but clearly a local militia.

'No wonder the water quality won't cooperate.' A Ling said softly, 'Someone is deliberately dumping waste.'

'This isn't negligence; it's about controlling the water source.' Su Qing packed up her equipment, her tone sinking: 'They're not letting the locals drink clean water, perhaps to force them to relocate or to monopolize water rights.'

'So are we still going to do it?' A Liang felt a bit uneasy, 'They've got guns.'

'Precisely because they have guns, we must act.' A Ling swung her backpack onto her shoulder, 'We're carrying water purification kits, not tanks. The kids are too sick to get up—who cares whose flag it is?'

Back at camp, the three immediately launched the backup plan. A Ming adjusted the 3D printer settings, reducing the structural part originally used for the fixed bracket by one‑third and turning it into a detachable clip; A Ling organized a dozen or so slightly older African children into a line, giving each two sealed water‑purification bags and teaching them how to connect the filter cartridge and manually pressurize to draw water; Su Qing spent the night writing an operation manual, translating it into the local language, printing it out and posting it beside each unit.

By noon the next day, the mountaintop water tank had been connected to three filter modules; when the first batch of purified water flowed out, the whole village gathered. An old man lifted a ceramic bowl, took a sip, and his eyes instantly reddened. The children clapped and jumped; one little boy flung himself into the drainage ditch to wash his face, splattering himself all over.

But just then, three rundown pick‑up trucks roared into the village, tires kicking up clouds of red dust. Three men in camouflage trousers jumped out, guns at their waists; one kicked over the transition box linking the main water pipe and shouted a few words nobody could understand.

A Ming stood before the equipment, unmoving: 'What are you doing?! This is for everyone's drinking water!'

That man shoved him aside, spat on the ground, then pulled a crumpled paper from his pocket bearing some kind of seal, and read it aloud to the villagers. Nobody understood his words, but the meaning was clear: dismantle the equipment, stop using water immediately, or bear the consequences.

'They say it's "illegal water extraction,"' a boy who knew a bit of English translated, 'They claim this river belongs to the warlord, and anyone who uses it must pay.'

'Bullshit!' A Liang jumped up in anger, 'The water's poisoned to that extent, and they still have the nerve to charge for it?'

Su Qing grabbed his arm, speaking low: 'Don't confront them head‑on; preserving what we've achieved is more important.'

She quickly opened the Tablet, connected to the encrypted network, and started a live stream. The camera swept over the smashed pipes, overturned filter boxes, and finally focused on the thin figures of the children queuing for water.

'This is Maru Village in District 12 of southern Kenya,' she said evenly, 'We are a civilian tech team, carrying our own low‑cost water purification system designed in‑house to help the locality face the drinking‑water crisis. So far the first five units have been deployed, each capable of delivering three thousand liters of clean drinking water per day. But after less than six hours of operation, armed personnel forcibly destroyed them and accused us of "illegal water use".'

She paused, eyes locked on the lens: 'I want to ask one thing—when a river is artificially polluted and the people have no water to drink, who is really breaking the law? We didn't come to seize resources; we came to save lives. If saving lives is illegal, then shouldn't this law be changed?'

As the video uploaded, it was simultaneously pushed to multiple international humanitarian platforms. She closed the Tablet, turned to the Triplets and said: 'Pack up, withdraw.'

'What about the gear?' A Ling pointed at the remaining equipment.

'Keep half, hide half.' Su Qing gave the order quickly: 'Distribute all thirty of the already‑produced portable water‑purification packs to the villagers, each person taking two bags Go Home to hide. Mark them with numbers so we can later track usage remotely. Take the main printer and data drive with us; dismantle everything else that can be taken apart and scatter the parts among the households.'

The three sprang into action. A Ming had a few kids stash the core components in the firewood pile and hide them in wall cavities; A Liang buried the battery pack at the bottom of the stove pit; A Ling kept the biofilm sample close to her body, and before leaving she slipped a candy into each child's hand.

'Can we fix it tomorrow?' a little girl tugged at her sleeve and asked.

'Of course.' A Ling smiled, ruffling her hair, 'We're just moving the work to another spot.'

At three in the afternoon, the entire youth tech team withdrew to the edge of the village, to a small church hut. The hut was low‑crouched, its plaster peeling, a cross hung above the doorframe. They piled their luggage in a corner and opened the ventilation window. Outside the sun blazed, cicadas chirring nonstop.

A Ming sat on a wobbly wooden chair, panting, 'The printer still works, and we have enough material for two more days.'

'All the data is here.' A Liang patted his backpack, 'We've recorded the whole process of them smashing the machine.'

Su Qing stood by the window, sending off an encrypted message. She turned to look at the three children: 'Now we wait for a reply. But we can't stop; as long as we have power, we'll keep producing the water‑purification packs.'

A Ling took a sheet of paper from her bag and spread it out—it was the upgraded, anti‑tamper design for the next phase. She penciled a note in the margin: thicken the casing, build in a buzzer alarm, change the manual pump to dual channels.

A dog barked outside. Down the mountain road, a pick‑up truck crept past, the silhouette in its cargo bed glancing this way.

Su Qing didn't dodge; she remained at the window. She saved the final log entry and shut off the equipment's power.

A Ming suddenly said, 'Actually we don't have to force a confrontation. We could try to link up with a nearby stationed medical team—they have protective credentials.'

'Let's wait for word.' Su Qing sat down, sipped some warm water, 'Someone will surely hear us.'

A Ling kept her head down, continuing to draw; the pencil tip whispered across the paper.

A Liang gazed at the sun‑bleached clearing outside the door and suddenly said, 'You think… they might come searching at night?'

No one answered.

The indicator light on the printer in the corner blinked, the green light steadily pulsed.
