A snowfall continued for two consecutive days.

The sunset over West Mountain, with the afterglow of the setting sun amidst the wind and snow, appeared absolutely beautiful, yet... desolate.

The orange-red sunset illuminated the scattered white snow, casting a unique color.

A halo of red, snow falling halfway up the mountain.

Big Camphor Tree Base, Inner City.

No one paid attention to this beautiful scene, focusing intently on their tasks at hand, as the sun was about to set. They needed to finish setting up the greenhouse as soon as possible.

At this moment, the heating system had already been installed.

He Bing, holding the walkie-talkie, contacted Li Hang in the power room: "Hang, the connections here are done. You can turn on the circuit breaker and test it."

Upon hearing from He Bing, Li Hang immediately flipped the switch for the circuit breaker linking the greenhouse in the Inner City.

"The circuit breaker is on, check it from your side."

On He Bing's side, he looked at the heating vent, and within a few seconds.

Whoosh whoosh whoosh ~

The heating system started blowing warm air.

"It worked, it worked!!" Cheers erupted among everyone in the greenhouse.

Li Yu's lips curved into a slight smile, as long as the heating was resolved.

Despite an afternoon of effort, they hadn't managed to complete all the installations in the greenhouse.

But the basic heating was already taken care of, and the lighting for illumination was also installed.

As Li Yu watched the weakening sunlight with the setting sun, he said to He Bing, "Turn on the lights!"

He Bing immediately activated the lighting system inside the greenhouse.

Ding——

A row of lights lit up the greenhouse brightly, even more so than during the day.

Amid the cheers, Li Yu said to He Bing, "Alright, turn on the other greenhouses too. We're burning the midnight oil to get this done!"

He Bing could control all the lighting, irrigation, and heating systems inside and outside the city through a central control system installed in the Inner City.

Of course, each greenhouse also had an individual control system.

However, if there was a main circuit switch in the Inner City, it controlled all the circuits in the greenhouse.

Outer City.

After receiving the message from He Bing, Xiao Qian also switched on the greenhouse's systems.

Each greenhouse tested showed no issues.

Thus, the heating and lighting of the greenhouses were resolved.

Next, the irrigation and other systems were the remaining tasks.

After the heating equipment in the greenhouse was activated, the temperature inside didn't rise quickly, as the greenhouse was quite large.

Ventilation equipment was also in operation, with outside air being processed and slowly delivered into the greenhouse.

An Ya and others were laying out the irrigation pipes, with drip irrigation being the most water-efficient method.

Time passed slowly, and the sun set unnoticed, while people inside and outside the city continued their work.

In the dining hall of the Inner City, Aunt Zhou and others were busy preparing meals. Due to providing for some extra staff these days, they had to cook more food.

After the sun set, the outdoor temperature gradually fell.

But since they had already covered the sun panels and completed the heating and lighting systems, staying in the greenhouse with the heating on, the temperature inside the greenhouse gradually rose.

Half an hour later, it reached 15 degrees.

Time passed.

The sky turned completely dark.

But everyone was still busy with tasks inside the greenhouse.

By now, the outside temperature had dropped to minus 20 degrees, but inside the greenhouse, the temperature reached 20 degrees. After reaching this temperature, it was adjusted to a constant temperature mode to maintain it.

The snow covering the soil in the greenhouse also slowly melted into water due to the rising temperature, making the soil moist.

The people walked around the greenhouse, and the soles of their shoes were soon covered with mud from all the walking.

At 7 PM, Aunt Zhou and others, braving the wind and snow, pushed carts loaded with several large containers of food over.

Supplying meals for hundreds of people wasn't a simple task, with Aunt Zhou and seven or eight others busily cooking.

Inside one of the largest greenhouses.

Those from other greenhouses had all gathered here.

Fortunately, the temperature inside the greenhouse was now 20 degrees, so everyone ate inside the greenhouse.

Li Yu watched as Aunt Zhou distributed the food and asked, "Aunt Zhou, did you prepare the food for the Outer City like we talked about earlier?"

Aunt Zhou, while holding a ladle, replied to Li Yu, "Yes, yes, your Second Uncle just took Zhengping and the others and pushed the food out."

Li Yu nodded slightly. He was also busy and couldn't handle everything personally, but Aunt Zhou's words reminded him he had asked Second Uncle to help take the food over earlier.

They couldn't possibly pull an all-nighter building without having a meal to eat.

Dapao sat indelicately on the concrete floor in the middle, eating noodles, taking a bite of garlic, then a bite of noodles, and said to Li Tie beside him, "I'll admit, it's actually pretty comfortable in this greenhouse despite the noise."

Li Tie wiped the sweat from his forehead, as he always got hot while eating.

The temperature in the greenhouse rose to 20 degrees, so he took off his outerwear, only wearing a short-sleeve shirt.

"With it being so cold outside, and the temperature in here just right, it's definitely comfortable," Li Tie said, hanging his outerwear on a nearby rack.

Dapao looked up at the bright lights above in the greenhouse, which used a double-steel-frame structure.
