What's needed here is not the intense sunlight simulating the cliff face, but rather soft, diffused light penetrating through the gaps in the tree canopy.
Su Wei selected six independent LED spotlights, along with diffusers and an adjustable color temperature module.
The angle of each spotlight needs to be set individually.
This allows light to be projected onto the dead wood and moss from different directions, simulating the effect of moving light spots in the forest.
Six lights, six angles, six independent signal lines.
Su Wei stood in the center of the Woodland Base, looking up to examine the reserved installation points on the ceiling.
You can't just turn on this light randomly.
The silver-gray texture of the driftwood looks best in sidelight; direct light will flatten all the details.
Mosses need diffused light; direct sunlight will scorch the cell walls on the surface of the leaves.
He marked six points on the ceiling with chalk, and wrote down the pitch angle and horizontal rotation angle of the light fixture next to each point.
Installation, wiring, angle adjustment.
Another hour and a half passed.
Go downstairs.
River valley area.
Su Wei squatted at the edge of the Moss River Valley, inspecting the pipes of the water mist sprinkler system.
Six ultrasonic atomizers have been installed in concealed recesses on both sides of the river.
Their nozzles faced upwards, obscured by pebbles and moss.
The power cords emerged from the conduit and Su Wei connected them one by one to the control module.
The atomizers are not very powerful, each only 48 watts.
However, when six units are connected in parallel, the current will be superimposed, so an independent air switch must be installed in the circuit.
He took six miniature circuit breakers out of his toolbox and put them into the distribution box in the valley area.
Tighten the lugs, screw them in place, and close the cover.
The situation is more complicated over at the tidal pool.
The heating element has a power rating of three kilowatts.
The start and stop of the wave generator pump requires frequency converter control.
The Neptune Poseidon chiller unit itself comes with an independent electrical system.
When all three sets of equipment are running simultaneously, the peak current will exceed forty amperes.
Su Wei crawled into the equipment room on the side of the tidal pool.
This space, less than two square meters in size, was crammed with frequency converters, contactors, and a row of circuit breakers.
He took off his windbreaker, leaving only a long-sleeved undershirt, and squeezed in sideways.
The output of the frequency converter is connected to a wave generator pump.
Su Wei pressed the four power wires into the terminals and tightened them to the calibrated value using a torque wrench.
The contactor's coil control line is connected to the relay module of the central control console.
The temperature control probe of the heating rod has been inserted into the basalt crevice at the bottom of the pool, and the signal line runs along the pool wall all the way to the equipment room.
Su Wei connected the probe signal line to the input terminal of the PID temperature controller, and then set the target temperature and upper and lower limit alarm values.
Every connection point, every wire.
He squatted in the equipment room for forty minutes.
When I came out, the back of my undershirt was wet.
Matt walked over from the lobby on the first floor, holding a stack of completed clip lists.
"All pipework on the first floor has been tightened and insulation tests have passed."
Su Wei took the list, glanced at the data, and nodded.
"Basement."
The two walked down the narrow stairs one after the other.
The basement space is not large, and all four sides are cast-in-place concrete walls.
A 1.2-meter-tall industrial-grade electrical distribution box stands in the very center.
A red high-voltage warning label is affixed to the dark gray metal casing.
Su Wei pulled open the door of the electrical distribution box.
The internal three rows of air switches are neatly arranged.
The top row contains the main switch and main circuit, the middle row contains the branch circuits for each exhibition area, and the bottom row contains the signal system and low-voltage lighting.
All the wires, from the lights on the second floor to the water pump on the first floor, from the ceiling to the floor, all converge here.
Su Wei pulled out his insulated gloves and put the thick rubber gloves on his elbows.
He pulled down his goggles.
Matt took two steps back and leaned against the concrete wall.
Su Wei pressed his left hand against the metal frame of the distribution box, while his right hand rested on the handle of the main switch.

Every single wire inside the distribution box became crystal clear at that moment.
From the main incoming line to the end load, every node the current would pass through, every contact surface, and even the tightness of every screw—all of this flooded into his mind.
It's not loose.
There was no false connection.
There is no misalignment.
Su Wei switched off the main switch.
Click.
A dull, metallic clanging sound.
Then comes the branch circuit.

Buzz €€€€
A low-frequency electrical hum emanated from inside the distribution box and spread along the metal casing.
The contactor clicked three times in a row as it engaged.
The inverter's display also lit up, and the green numbers fluctuated for two seconds before stabilizing.
Then, everything fell silent.
The entire exhibition hall fell silent for a second.
Su Wei removed his goggles.
Matt stood behind him, his icy blue eyes fixed on the row of green indicator lights on the distribution box.
