The World Ends In 27 Days

Chapter 81: Warmth Was a System

Qinghe began the Freeze shelters inspection at Beiyuan Geothermal Station the day after they went through all the Flood shelters.

The protected living structure had been built into bedrock beyond the mapped volcanic hazard zones. The idea was that the geothermal wells supplied heat and hot water through three sealed exchange systems, while generators converted excess thermal energy into electricity.

No single well was required to keep the shelter warm, but more heat was always better.

Shichen had divided the residential core into independently heated sections. If one circulation loop failed, doors could seal the affected area while the other two maintained safe temperatures.

Qinghe approved the design for a reason none of the construction reports mentioned.

Cold didn’t kill only through exposure.

It thickened blood, increased strain on the heart and made every existing injury more painful. Inadequate heat would affect judgment and coordination before anyone recognized how impaired they had become.

Zhiyi walked beside the geothermal equipment with her tablet open. She verified 18 replacement circulation pumps, 72 valve assemblies and enough seals, lubricants and treatment chemicals to maintain the closed loops for more than four years.

"Backup heat?" she asked.

Shichen showed her six electric boilers and 120,000 liters of stabilized fuel stored in protected tanks. "The boilers can maintain the residential core if every geothermal loop fails."

Zhiyi checked the fuel measurements rather than accepting the delivery manifest.

Beiyuan’s clothing inventory contained 72 complete outerwear sets, 144 thermal base-layer sets, 36 pairs of insulated boots and 240 pairs of wool socks. Sixty sleeping bags were rated for temperatures far below anything permitted inside the shelter.

Qinghe added chemical warming packs, heated blankets and equipment for treating hypothermia.

The food contained a larger proportion of fats, powdered dairy and high-calorie emergency meals than the Heat or Flood inventories. Zhiyi checked the quantities without opening the residential freezer.

It was empty and powered down.

Nothing perishable had been left inside a property they wouldn’t occupy for six years.

By noon, Beiyuan was complete.

Nanshui Pumped-Storage Station lay 90 kilometers south, far outside Beiyuan’s geothermal failure zone. Its critical infrastructure occupied caverns inside the mountain, protected behind access tunnels and reinforced doors.

Water released from the upper reservoir turned turbines before collecting below. Pumps could return it when excess power became available, creating a closed energy cycle.

"The upper reservoir will freeze," Zhiyi said.

"The surface will," Shichen agreed. "The intake is below the projected ice depth, and the pressurized conduits remain inside the mountain."

Zeyu had supplied remotely operated drilling equipment in case ice blocked an exterior access point. Jingwei had secured three routes into the station, including an emergency tunnel invisible from the public road.

Qinghe inspected the residential heating system. Waste heat from the turbines supported the primary loop, with electric boilers and 160,000 liters of stabilized fuel providing backup.

Nanshui held the same winter clothing quantities as Beiyuan, plus 24 flotation suits for work near open water and 12 insulated rescue harnesses.

Zhiyi selected replacement components from the turbine, pump and heating inventories. She compared serial numbers, confirmed storage conditions and marked each category complete only after the physical stock matched her records.

She checked food, medicine and water with the same precision.

The freezers remained off, because there was no point in wasting electricity in a place that they weren’t currently living in.

Hanchuan watched her pass them without opening the doors, his expression revealing nothing.

Longyuan Military Archive was the final property.

The abandoned archive had been built to survive attack rather than weather, but that didn’t mean it wasn’t suitable.

Its buried reinforced structure contained multiple controlled entrances, fuel storage and enough interior space to create insulated living areas without weakening the exterior shell.

The old systems had been removed.

New ventilation, heating and electrical networks followed the same protected-core design used throughout the other shelters. Longyuan lacked geothermal energy and moving water, which made its fuel reserves more important than those at Beiyuan or Nanshui.

Four underground tanks contained 480,000 liters of stabilized fuel. Separate generators and boilers occupied isolated mechanical rooms so a fire or failure in one couldn’t disable the others.

Zhiyi reviewed the consumption model.

"At minimum residential load, this exceeds four years."

"It includes power for repairs, ventilation and food production," Shichen explained. "It also includes a 20 percent loss margin."

She recalculated the totals before accepting them.

Longyuan stored more replacement burners, pumps and filters than the other Freeze shelters because every degree of warmth depended upon machinery they needed to maintain themselves.

Qinghe inspected the medical room last.

Its equipment could treat burns, frostbite, fractures and respiratory illness. Medicines vulnerable to freezing occupied insulated cabinets inside the protected core. Every fluid that might expand and rupture had been stored within temperature-controlled containment.

Nothing had been left near an exterior wall merely because the room remained above freezing today.

When Qinghe returned to the main corridor, Zhiyi was checking the final clothing cases.

She counted the sealed vacuum packages before comparing their sizes with the personal records. Hanchuan stood close enough to touch the back of her neck but didn’t interrupt.

The other three men had begun to relax.

Zeyu had stopped pretending not to be impressed by the fuel tanks. Jingwei approved the separate entrances, while Shichen looked at the completed structure with the exhausted satisfaction of someone who had finally reached the end of a schedule.

Qinghe understood their relief.

Nine shelters stood ready.

If the disasters occurred, they had done everything possible to survive them.

If they didn’t, no one had been harmed by possessing food, hospitals, power stations and secure buildings.

Only Zhiyi didn’t appear relieved.

She marked Longyuan complete and immediately reopened the full property list as though another task might appear beneath it.

There wasn’t one.

"Everything is here," Qinghe told her gently.

"I know," she replied briskly with a nod of her head.

Her answer wasn’t disagreement. It sounded more like she didn’t know what to do with the fact.

Qinghe didn’t ask her to explain it because he didn’t want to start upsetting her.

On the other hand, Hanchuan had already noticed, and his hand remained steady against her neck while she stared at nine completed property records.

All three Freeze shelters were finished.

What was Zhiyi going to do now?
