Chen Hao's hand was still stuck in the soil, his fingertips covered in dark, fungus-rich soil. He paused for a moment, then quickly pulled it out, shook it a couple of times, and wiped it on his pants.

"Oh dear, we'll have to start planting again now." He said, looking down at the "Nana No. 1" seedling that had been bent over.

Nana had already reached the west side of the platform, where a robotic arm was disassembling a metal box. "The main control valve is ready for installation," she said. "Please assist with connecting the pre-installed piping."

"Here it comes." Chen Hao wiped his face and bent down to grab the wrench. His knee cracked again, and he frowned but didn't say anything.

He squatted down at the interface, aligned the valve with the pipe opening, and pressed it down. After just one turn, water seeped out from the gap, dripping down the threads.

“Something’s not right,” he said. “The opening is too small.”

Nana's probe scan: "Model mismatch. The original design used a standard M20 interface, but the actual pre-embedded part is an old-style tapered thread."

"So, we've worked for nothing?"

“A temporary adaptation solution is feasible.” She pulled up some data, “A transition flange needs to be made.”

"It sounds like cooking."

"The metaphor is incorrect."

“I know it’s a connector.” He opened his toolbox and found a piece of scrap metal. “I had some leftover material from the last time I repaired the resin tank, so I’ll make do with it.”

Nana handed him the welding torch, and Chen Hao put on his goggles. A flash of light, and the edge of the sheet metal began to glow red. He heated it while gesturing the shape, his hands trembling slightly, but he kept steady.

"I never used to shake like this when I was cheating on exams," he muttered. "Now I get nervous just fixing a water pipe."

"You were once punished by being late and had to stand for three classes."

"You still remember?"

"Archive all actions."

"I'll have to format your system sooner or later."

The welded flange was installed, and the four bolts were tightened. Chen Hao breathed a sigh of relief: "Let's give it a try."

Nana started the test procedure. Water flowed through the new connector, dripping at a uniform rate, with no leaks.

"The sealing meets the standards," she said.

"That's it then." Chen Hao clapped his hands. "Automated irrigation, officially online."

No sooner had he finished speaking than a jet of water suddenly shot out from the end of the drip irrigation pipe, hitting the edge of the flowerpot and splashing all over the ground.

"...Maybe the pressure wasn't adjusted properly," he said.

Nana immediately cut off the water supply. "Pressure testing incomplete. The temporary structure poses a risk."

"Does the meaning need to be changed?"

"It is recommended to replace it with standardized parts."

Where to look?

"The analysis of the remaining equipment in the surrounding industrial area is complete." She pointed to a partially collapsed factory building in the distance. "There are usable valve modules in the hydraulic control station."

Chen Hao looked over and frowned: "That place almost killed someone last time."

"Remotely non-disassembly".

"So I have to go?"

“I can provide support.”

He stared at the building for five seconds, then sighed, "Fine. But it's agreed, you'll be in for five minutes, grab it, and leave."

The two set off with a cutter and a portable power supply. On the way, Chen Hao kept muttering, "If I die in the ruins, remember to bury me far away, so as not to affect the feng shui of the base."

This function is not available.

"Can't you offer some comfort?"

"The current probability of death is 3.2 percent."

"Is this what you call comforting?"

They arrived outside the control station. The walls were leaning, and the steel bars were exposed. Nana first used a robotic arm to probe into a gap and brace a beam that was about to break.

Chen Hao crouched down and crawled inside, crushing several concrete slabs under his feet. He reached the control panel, opened the casing, and found a hydraulic pump inside, intact.

“There really is some.” He grinned and raised the cutter, aiming it at the connecting shaft.

Amidst sparks, the metal shaft was severed. Nana used her robotic arm to support the pump body and slowly pulled it out.

I had only retreated less than ten meters when there was a loud crash behind me, and half of the wall collapsed.

Chen Hao stood still, catching his breath, and said, "Next time you suggest somewhere to go, I'll vote against it."

"Mission successful."

"Congratulations!"

Back at the base, he placed the hydraulic pump on the control panel and wiped the sweat from his brow. "This thing is so big, how do we fit it into the irrigation system?"

After scanning, Nana responded: "Power source incompatible. Cannot be directly connected to electric drive."

"Then it's useless."

"Not necessarily." Chen Hao suddenly looked up. "It relies on hydraulics, which is very powerful. Could we change it to manual? For example, by using a foot pedal to store the power?"

Nana paused for two seconds, then brought up the modeling interface. "Feasibility verification in progress... Intermittent pressurization can be achieved through a spring energy storage device."

"I always said that humans are sometimes more useful than databases."

"Not yet proven."

"Just you wait and see."

They began the modification. Chen Hao was in charge of designing the foot pedal structure, welding a lever support out of old steel pipes. When stepped on, it would drive a piston to compress the liquid, and the pressure would be stored in a sealed chamber.

Nana wrote a simple release logic: when the pressure reaches the threshold, the solenoid valve opens automatically, pushing the water flow into the main pipeline.

During the first trial run, after treading the pedal ten times, the valve clicked open. Water rushed into the pipe, and the drip irrigation heads dispensed water one by one at a steady pace.

"It's done?" Chen Hao's eyes widened.

"Initial operation is normal." Nana recorded the data. "Pressure fluctuations are within the allowable range."

"Ours is purely handmade and high-tech."

The technology is rated as 'rudimentary but effective'.

"That's a really harsh comment of yours."

As he was speaking, he caught a glimpse of the ewes huddled together in the sheepfold, clearly indicating that they were in their lactation period.

“Mixing milk every day is exhausting.” He scratched his head. “Is there any way to make this hydraulic pump do something else as a side job?”

Nana looked at the resin container: "It can be modified into a squeeze-type separation device."

"What do you mean?"

"Using pressure to push goat milk through a filter, the fat and whey are initially separated."

"It sounds like a juicer."

"The principles are similar."

"Let's do it!" Chen Hao perked up. "The pump's been sitting idle anyway."

They removed the irrigation connection pipe, fixed the resin container to the front of the pump body, and installed a stainless steel filter screen in the middle. The outlet splits into two lines: one connects to the baby bottles, and the other drains wastewater.

The first round of testing used room temperature water as a simulation. The foot pedal stored energy, the pressure increased, and the water was pushed through the filter screen, splitting into two streams.

"The separation efficiency is considerable," Nana said.

"That's the real deal."

They brought over a lactating ewe and positioned her. Chen Hao attached the teat to her and took a deep breath.

"Power on."

Foot pedal start. After ten presses, the pressure is released. The milky white liquid flows into the container, passes through the filter under pressure, and the clear milk and concentrated milk flow into different receiving tanks respectively.

Thirty seconds later, the process ended.

Chen Hao picked up the bottle full of concentrated milk and held it up to the light: "Can this stuff be used to make cheese?"

“It can be fermented to make simple dairy products,” Nana responded.

"We've got breakfast and snacks sorted out now," he laughed. "This isn't just a farm, it's a processing plant too."

"The dual-process integration has been initially completed."

“You manage the planting, I’ll handle the breeding and processing.” He patted the machine. “That’s called a clear division of labor.”

Nana scans the running data: "First batch processing completed, efficiency achieved 120%."

"It's better than I expected."

He wiped the sweat from his forehead, walked to the small stool next to him, sat down, and picked up a cup of warm goat milk that he had just received.

“Come on, let’s celebrate the start of production,” he said, taking a sip and grinning.

"How does it taste?" Nana asked.

"It has a mild muttony smell and smells quite nice." He raised his glass. "How about we name it 'Chen Hao Brand Fresh Milk No. 1'?"

"The naming does not conform to the specifications."

"You can't expect me to call it 'Product A-7', can you?"

“We can number them.”

"Boring."

He finished the last sip and put the cup down. "Shouldn't we consider mass production next? Pack more containers, and process three sheep at a time?"

"The support structure needs to be reinforced to prevent damage from resonance."

"Then we'll thicken the steel plates."

"Insufficient material inventory."

"Shall we go scavenge some more from the ruins?"

"The risk factor has increased."

"It's alright." He stood up and stretched. "As long as the building doesn't collapse, I'll accept it."

Nana turned to the machine, and the robotic arm gently supported the machine body. The extruder was still vibrating periodically, emitting a low, compressing sound.

The irrigation system drips water in an orderly manner, with a thin stream seeping out from under each cucumber seedling.

Chen Hao leaned against the sheep pen fence, watching everything proceed as usual.

Do you think we're at the beginning of industrialization?

Nana turned her head, and the optical mirror flickered slightly.

"By definition, it already possesses the basic characteristics of automation."
