Chapter 145

Su Jing stood in front of the workbench in the basement control room of the villa, her fingertips tracing the spread-out fragments of manganese ore—

These are high-level ores brought back from the "Wilderness Monster World" dungeon. They gleam with a pale blue light, and you can feel the stable energy contained within them when you touch them with your fingertips.

On the workbench were metal components salvaged from the robot's spare parts: a miniature water pump, a humidity sensor, a multi-directional nozzle, and a roll of high-temperature resistant silicone tubing.

What she needs to do is use her supernatural abilities to fuse manganese crystals with these components using the minerals, creating a spirit herb irrigation device that can automatically water plants.

"Su Jing, can these shiny stones make the water pipes flow by themselves?" Little Jin squatted on the edge of the workbench, its short golden fur dusted with ore powder, its black eyes fixed on the manganese crystal fragments, its voice filled with curiosity, its little paws gently digging at a silicone tube.

"Previously, you had to press a button to water the plants with the robot. Can this one be made without pressing a button?"

"Yes, the energy of the manganese crystal can drive the water pump. With the addition of a humidity sensor, it can sense the dryness or wetness of the soil and automatically water the plants."

Su Jing smiled and picked up a manganese crystal fragment the size of a fingernail, a faint blue glow emanating from her fingertip—

When her mineral-controlling ability is activated, she can clearly "see" the energy patterns inside the manganese crystal.

She placed the fragment at the core of the miniature water pump, channeling her supernatural power into it through her fingertips. The pale blue energy patterns slowly merged with the pump's metal circuitry, and a faint blue light instantly illuminated the pump's surface. The display screen then showed "Energy access successful, standby power 1W".

Little Jin leaned even closer, her little nose almost touching the water pump. "Wow! It's lit up! It's even prettier than the robot's lights!"

It suddenly remembered something, ran to the nearby parts box, and used its paws to pull out a small humidity sensor.

"Can you tell if the soil is dry by putting this in the ground? You always used this to test the soil when we were planting spirit herbs!"

“Yes, that’s it.” Su Jing took the sensor, embedded another, smaller fragment of manganese crystal into the sensor’s probe, and injected her supernatural power again—

This time, she specifically controlled the energy intensity to ensure that the manganese crystal and the sensor's sensing chip were perfectly aligned.

"This way, the sensor can measure the humidity of the spiritual soil more accurately, with an error of no more than 5%. The humidity requirements of the Qi-gathering grass, the hemostatic grass, and the thousand-year spiritual grass are different, so we can set thresholds for them separately."

As assembly began, Su Jing first fixed the miniature water pump, which incorporated manganese crystals, into the silver metal shell. The water pump's inlet was connected to a silicone tube, and the other end extended to the pure water storage tank in the space.

The water outlet was connected to three multi-directional nozzles, each capable of rotating 360 degrees, providing just enough coverage to reach a row of medicinal herbs in the planting area. Next, she connected the humidity sensor's cable to the water pump's control chip, reinforcing the interface with her mineral-based magical abilities—

The pale blue energy condenses into a thin film at the interface, which can prevent the circuit from loosening and reduce energy loss.

"Number 3, come over and test the water pump head."

Su Jing gave the order to the robot waiting beside her. Robot No. 3 immediately moved to the workbench, and its robotic arm lifted the irrigation device, aiming the nozzle at the empty water bucket next to it.

Su Jing lightly tapped the start button on the water pump, and the manganese crystal core instantly lit up. The miniature water pump started with a "hum," and clean water flowed through the silicone tube into the nozzle, sprinkling evenly into the bucket.

The display screen simultaneously shows "Current humidity threshold: 60% for the aerobic grass area, 55% for the hemostatic grass area, and 50% for the millennium spirit grass area. The water pump head is 0.5 meters, which meets the height requirements of the planting area."

"Success!" Little Jin jumped excitedly on the workbench, accidentally knocking over a silicone tube. It hurriedly pressed it down with its paw.

The voice in her mind was apologetic: "I'm sorry, I'm sorry! I didn't mean to!" Su Jing smiled as she picked up the tube and reconnected it. "It's okay, I'll make two more. There are three sections in the planting area. I'll put one in each section, which will be enough to cover all the spiritual herbs."

Over the next two hours, Su Jing built two more irrigation devices following the same steps.

Each unit has its parameters adjusted according to the needs of the corresponding zone's spirit herbs: the irrigation nozzles in the aerobic grass zone have a higher density, and the watering time is 10 seconds per cycle.

The spray nozzles in the hemostatic herb area have a gentler angle to prevent water from knocking over the seedlings; the irrigation system in the thousand-year-old herb area has reduced the number of nozzles and a single watering time of 5 seconds to prevent excessive water from causing root rot.

Xiao Jin helped hand over parts and wipe away ore powder throughout the process, and occasionally reminded her with her mind: "Su Jing, this manganese crystal fragment is a bit small, will it not have enough energy?"

Su Jinghui patiently explained, "The energy in these fragments is enough to power the irrigation system for 30 days. Then you can just replace one of them. It's very convenient."

As the three irrigation devices were moved into the space's herb planting area, the setting sun was already shining through the small window of the control room.

Su Jing placed the irrigation devices according to the zones: the one for the aerobatic grass zone was placed in the east corner, with the nozzles aimed at the rows of seedlings;

The hemostatic herb area is placed next to the central passage, with silicone tubing extending along the edge of the sacred soil;

The herbs in the Millennium Herb area are placed next to the cultivation box, with the spray nozzle set to fine mist mode.

She pressed the main start button, and the three irrigation devices lit up with a faint blue light at the same time. The humidity sensor was automatically inserted into the soil, and the display screen showed "Irrigation device is connected to the network. The current soil moisture in the aeration grass area is 58%, which is below the threshold. Watering will be carried out in 10 seconds."

Ten seconds later, the nozzles in the aerobatic area sprayed out a fine mist of water, which landed evenly on the roots of the seedlings without splashing a single drop onto the cotyledons.

Su Jing used a miniature scanner to check the soil moisture, and it quickly showed "60%, reaching the threshold, the irrigation device is on standby".

"I don't need to come and water it every day anymore; the irrigation system will take care of itself." She breathed a sigh of relief and said to Xiao Jin in her mind. Xiao Jin was lying next to the irrigation system in the Millennium Spirit Herb area, gently touching the fine mist spraying from the nozzle with its paw. "So I don't have to hand the robot the watering can anymore? Then I can help you loosen the soil more!"

After finishing with the irrigation equipment, Su Jing didn't rest. She walked to the temperature monitoring screen in the space and looked at the records: In the past three days, the temperature in the underground operating room has risen from -5℃ to 2℃, and the temperature inside the space has also risen from 25℃ to 27℃.

She frowned, and memories of the apocalypse from her past life suddenly flooded her mind: after the extreme cold, there would be a continuous heat wave, with the surface temperature reaching 60°C. Without cooling equipment, spiritual herbs would wither and die, and food would spoil.

"We need to prepare in advance for extreme heat."

Su Jing immediately went to the material storage area and transferred the heat-sensitive flour and rice to the temperature-controlled shelf (temperature set at 15℃). She also checked the ventilation system of the spirit herb planting area and increased the power of the exhaust fan.

She opened the communicator's points panel and looked at the number "30,000+ points". She made a plan in her mind: Tomorrow she would buy solar cooling equipment and sunshade materials from the system store. The planting area needed shade, and the operating room also needed to be equipped with cooling equipment, otherwise the robot would malfunction under high temperatures.

Xiao Jin seemed to sense her seriousness, ran to her feet, and rubbed her trouser leg with its little paws. Its voice softened in its mind: "Su Jing, is it getting hot? Can we eat ice when it's hot? You said before that ice is cool and delicious."

Su Jing squatted down and touched its head, and it responded consciously: "It's getting hot. Once we buy cooling equipment, we can use the pure water from the space to make ice cream, which can also cool down the spirit herbs."

Xiao Jin's eyes immediately lit up. "Great! I want sweet ice, the kind with crushed spirit herb seeds in it!"

Su Jing smiled and nodded, her gaze falling once again on the temperature monitoring screen—the extreme heat hadn't arrived yet, but it was always good to be prepared.

With the automatic irrigation system freeing her hands, she can now focus on preparing cooling supplies to ensure that the herbs, food, and Little Gold can all safely get through the upcoming extreme heat.
