Wasteland Hideout: Upgrading from the Sewers

Chapter 252: Wasteland Calendar Day 43, The Shelter Undergoes Another Major Upgrade

Over the next few days, Yu Yuan focused all his efforts on upgrading and constructing the shelter.

With Carmen at the Black Shield Police Department and Mona at the Aurora Animal Assistance Association, although he couldn't directly obtain the reserve supplies of these two factions.

The intelligence information provided by their organizations was enough for Yu Yuan to quickly locate the corresponding supply points and gather the necessary materials.

Furthermore, Carmen would arrange for Er Xiao to dismantle relevant areas in advance, providing ample convenience for Yu Yuan's material acquisition.

Finally, add in the massive purchase efforts on Taotao Hole.

The shelter's facilities were rapidly being updated and replaced.

[Multi-Layer Airlock Doors], [Environmental Shield Shell], [Air Pressure and Ventilation Duct System], and [Emergency Lighting System] were all upgraded to completion.

The [Security] main door was completely replaced with heavy multi-layer airlock doors, consisting of three sealed doors. Between the doors formed two closed transition chambers, and these doors could not be opened simultaneously.

Not only did the safety rating significantly improve, meeting the requirement of trading space for safety, but it also ensured the maximum isolation of the extreme cold outdoor air during the extreme cold weather.

The outermost layer of the entire shelter's walls was now encased in stainless steel plates, possessing strong corrosion resistance, anti-aging capabilities, and also ensuring waterproofing and airtightness.Hard polyurethane foam was added in the middle of the walls to act as an insulation layer, and all walls underwent "thermal bridge breaking" treatment, maximizing the preservation of temperature within the shelter.

After the shelter's [Ventilation] facilities were upgraded again, corresponding treatments for air heating were also implemented.

Although the shelter was built underground, and the previous optimization path for the [Ventilation] facilities was entirely aimed at utilizing soil temperature for air heating.

However, facing a cold wave with a minimum temperature of -98°C, it was still far from sufficient.

Yu Yuan implemented two measures. The first was to have the heating pipes from the [Geothermal Well Plate Heat Exchanger Room] perform the first round of heating at the ventilation intake duct of the shelter.

Relying on this first round of heating should be enough to cope with the low temperatures brought by the Super Storm Period.

The second preparation was the addition of a pre-heater at the ventilation intake within the optimized [Air Pressure and Ventilation Duct System], which could consume electrical energy to directly heat incoming air during critical moments.

The rotary heat exchanger within the ventilation ducts could then physically isolate but allow close flow between the warm exhaust air indoors and the cold fresh air outdoors, enabling the introduced cold fresh air to rapidly warm up under the influence of the warm exhaust air.

This achieved an energy-saving effect.

Moreover, the fully upgraded [Ventilation] facilities had sensors distributed throughout the entire shelter.

They could be directly controlled via an intelligent panel, monitoring and regulating the entire shelter's temperature, humidity, indoor carbon dioxide levels, oxygen concentration, and more throughout the process.

The above were only the shelter's peripheral insulation facilities.

Regarding indoor heating within the shelter, the heating pipes paired with the [Geothermal Well Plate Heat Exchanger Room] also covered the entire shelter, allowing control of indoor temperature by adjusting water flow velocity, which was quite convenient.

Of course, the current temperature inside the shelter was already around 25°C, the most comfortable temperature for the human body, so heating was not required, and the heating valve was temporarily closed.

But whenever needed, it could be opened at any time, and the temperature of the entire shelter could be raised in a very short time, more than sufficient to deal with the impending cold wave.

Additionally.

Considering the shelter's future development and the potential addition of other members, Yu Yuan simply converted one-third of the underground third-floor Core Living Area into more economical and compact [Single-Person Living Quarters], a total of 10 units.

Internal corridors, public bathrooms, public showers, laundry rooms, and other public facilities were also set up.

It could be said that space utilization was maximized.

Each [Single-Person Living Quarters] had a 9-square-meter space.

The bed was a 1.2-meter-high loft bed.

The space under the bed was a work and reading area, equipped with a desk and drawer storage cabinets.

Against the wall was a standard wardrobe and a storage box.

The rooms were simple, and the furnishings were relatively sparse, but for the current environment, it was already quite good. At least it gave everyone their own independent space, and it was fully functional.

At least after Yu Yuan completed the renovations, everyone especially liked them. Dale couldn't wait to carefully arrange his books in his room.

The central Living Area was also optimized and constructed with a kitchen, Leisure Area, and restaurant based on the existing layout.

Although the area was only a little over a hundred square meters, it was still warm and comfortable enough.

As for Mie Mie and Yu Yuan's Rest Area, there weren't many changes.

Of course, Yu Yuan had a separate bathroom and Workshop set up here, ensuring his own independent space.

The area that changed the most was naturally the underground fourth-floor space, which was also where Yu Yuan spent most of his energy these past few days.

Within the 600-square-meter area, [Mammal Breeding Room], [Poultry Breeding Room], [Insect Breeding Room], [Special Cultivation Zone], and [Hydroponics Room] were arranged clearly.

Among them, the areas occupying the largest space were the [Hydroponics Zone] and the [Mammal Breeding Room], which together took up 70% of the entire floor's area.

The remaining [Poultry Breeding Room] and [Insect Breeding Room] each occupied 10%, and the final 10% of space was allocated to the [Special Cultivation Zone].

This could basically meet future development needs.

The [Poultry Incubation Nest] was directly placed by Yu Yuan in the [Special Cultivation Zone], together with the Nizi Water Arrow Turtle and the green algae.

Over these past few days, [Yakov's Nest] would produce 3 to 5 duck eggs every day, all of which were placed by Dale into the [Poultry Incubation Nest] for incubation.

One of the functional effects of the [Poultry Incubation Nest] was a -50% incubation time, meaning it would take a minimum of 3 days to confirm whether the incubated duck eggs were unfertilized eggs.

——————————————

Wasteland Calendar Day 43.

Four days had passed since resolving the threats from the Stag Shelter and the Giant Mutant Rat.

In the morning, he woke up under the influence of his biological clock, leisurely stretching.

Checking the time, it was 6:29 AM.

It must be said.

After having people in the shelter share the workload, he finally didn't have to wake up precisely on schedule every day.

Walking out of the Rest Area, he saw the black furball Zhi Zhi lying on Mie Mie's head, currently circling around Fang in the kitchen, while Fang held a carrot, feeding it to Mie Mie.

After a few days of interaction, the Stealth Rat had become very familiar with every member inside the shelter. Although everyone knew the Stealth Rat was transformed from that fierce Giant Mutant Rat before.

But now, the Stealth Rat had no relation whatsoever to the mutant rat.

Moreover, the Stealth Rat's current appearance was adorably cute and clumsy, earning the affection of all members.

Especially Masier, who would hug and cuddle the Stealth Rat whenever she had time.

But for Zhi Zhi, its favorite was still Mie Mie, particularly enjoying lying on the soft fur atop Mie Mie's head; they were basically inseparable.

And Mie Mie didn't mind it much either.

A strange balance had thus been established.

The Doctor was also very interested in the Stealth Rat, constantly trying to see if he could draw some of Zhi Zhi's blood for experiments.

Unfortunately, Zhi Zhi was not a creature in the conventional sense. Although its body had tactile sensation, it was composed of a mass of black mist and shadow.

Rather than a biological entity, it was more appropriate to call it an energy body or conceptual entity.

After several failed attempts to obtain biological blood, the Doctor gave up.

Yu Yuan simply greeted Mie Mie, Zhi Zhi, and Fang, then headed to the fourth floor.

However, as soon as he descended the stairs, Dale spotted him and excitedly shouted:

"Boss, come quick! Look! The mealworms have started mating...."
