Chapter 1220
Zhang Jia looked at his slightly flustered appearance and the faint blush on his face, and couldn't help but laugh after her initial excitement.
She patted Xiao Sheng's head and said gently, "Our Xiao Sheng has grown up. He can even earn gifts for his older sister now."
When Tao Zheng learned about this, he simply said, "At least he has some conscience."
Zhang Jia gave him a reproachful look: "You can't keep such a blank face in front of Xiao Sheng!"
Mingming felt the same way about Xiaosheng, always picking him up from school and saving the best food for him.
However, he was not good at expressing concern and did not know how to show his love for Xiao Sheng, so he could only keep a blank face and show it through his actions.
The hot salt rain stopped a few days ago.
The temperature inside the mid-air fortress skyrocketed like a rocket.
It started at fifty degrees.
Then it's sixty degrees, then seventy degrees.
In just two months, the thermometer's red line soared to 90 degrees Celsius.
It felt like there was a fire burning in the air.
Taking a breath makes my throat burn.
Exposed skin can easily leave a red mark from a slight touch with a metal object.
People stayed indoors, afraid to go out.
But soon, something even worse happened.
Both air-conditioned clothing and winter clothing have encountered problems.
Qi Mingyu led his team to change shifts. As soon as they stepped out of the gate of the fortress, the thermostat on the back of their neck emitted a piercing electrical sound.
Immediately afterwards, the lining against my skin suddenly became hot, as if I were holding a red-hot branding iron.
He suddenly ripped open his collar, and the numbers on the display screen flashed wildly, turning into a jumble of gibberish.
"Shoot-"
White smoke was rising from the sleeve of someone nearby, accompanied by a burnt smell.
Mine is broken too!
"It's short-circuited! This lousy clothing can't withstand 90 degrees Celsius at all!"
Curses and insults rose and fell.
The team members hurriedly took off their clothes, and their exposed skin instantly turned red from the heat.
They quickly returned inside.
In just a short while, all seven or eight sets of air-conditioned clothing became useless, lying on the ground like a pile of scrap metal.
The news quickly spread throughout the fortress.
Residents also discovered that their air-conditioned clothing and winter coats either stopped working completely or their cooling and heating effects were greatly reduced.
Panic began to spread.
When these clothes were designed, the engineers did indeed consider the extreme weather of the apocalypse.
It can withstand temperatures as low as -50 degrees Celsius and as high as 60 degrees Celsius.
But no one expected the temperature to soar to 90 degrees Celsius.
This has exceeded the clothing's maximum load-bearing capacity.
The outdated refrigeration system simply couldn't withstand such high temperatures.
Either the circuit overheated and short-circuited, or the battery was overloaded and burned out.
People were completely trapped indoors.
Let alone going out to work, even walking around inside the fortress requires extreme caution.
The patrol team's work was also suspended.
Without the protection of air-conditioned clothing, going out would be suicide.
The defenses of the mid-air fortress suddenly developed a breach.
Fortunately, a backup plan was taken when the fortress was built.
The sentry posts scattered around the fortress were all connected to the internal ventilation system.
The air conditioner in the sentry post is still working properly.
The team members on duty huddled in their sentry post, using binoculars to keep an eye on the sea and sky outside.
My heart felt heavy.
The two captains immediately convened an emergency meeting.
The meeting had only one agenda item.
We urge research institutes to overcome the technical challenges of air-conditioned clothing as soon as possible.
"One week!" Captain Chen's voice was resolute and unwavering. "I don't care what methods you use, you must produce new clothes that can withstand temperatures of 90 degrees Celsius within seven days!"
"Otherwise, the entire fortress will be trapped!"
The task fell on Lin Wei's shoulders.
The entire research institute instantly entered a state of wartime readiness.
The buzzing of various instruments, the clanging of metal, and the clatter of arguments intertwined to create a sleepless cacophony.
Lin Wei's eyes were bloodshot from staying up all night. A thick stack of old blueprints lay in front of her, and her brows were furrowed in worry.
The principle behind air-conditioned clothing is actually not complicated.
It involves laying fine cooling pipes inside the layers of clothing.
Using a built-in miniature compressor, cooled air is delivered into the lining pipes to form a constant-temperature airflow layer.
At the same time, it is powered by a battery on its chest to maintain the operation of the temperature control system.
The fabric of the clothes can also insulate against high external temperatures.
They work together to achieve a cooling effect.
To put it simply, it's like wearing a mini air conditioner on your body.
The principle behind winter clothing is similar, except that it uses heating instead of cooling.
The problem now is that the old cooling system can't withstand temperatures of 90 degrees Celsius.
As soon as the compressor started, the temperature soared, and the wiring burned out quickly.
This system was sufficient when the temperature wasn't so extreme.
But it's different now.
In a high-temperature environment of 90 degrees Celsius, the compressor needs to operate under overload to reduce the temperature to a level that the human body can tolerate.
The old battery's range was insufficient, and the circuit board's heat resistance was inadequate, making overload and short circuits almost inevitable.
“We need to change the power source.” Lin Wei stared at the disassembled air-conditioning suit, her brows furrowed. “The old battery has too little power and can’t withstand high temperatures.”
“Don’t we have a new type of micro wind generator?” a team member suddenly said. “If we put that in our clothes and use wind power, it should solve the power problem.”
Lin Wei's eyes lit up.
The new micro-wind generator, about the size of a palm, generates electricity using airflow and has a range several times longer than the old battery.
If you put this inside an air-conditioned garment, the power supply problem will be solved.
But soon, new problems arose.
Material.
The fabric of the old air-conditioning suit was made of the same material as that used in spacesuits.
This material is lightweight, tough, and can insulate against extreme temperatures.
Before the end of the world, we had stockpiled a lot of supplies.
Over the years, it has been almost completely depleted.
More importantly, with the current technological level of the base, it is simply impossible to produce any more.
Without the fabric from spacesuits, what will be used to make the outer shell of the new air-conditioned suit?
We can't just use ordinary fabric, can we?
At a temperature of 90 degrees Celsius, ordinary fabric melts upon touch.
Moreover, the old air-conditioned clothes were badly worn out from years of use.
Some had holes, and some had worn-out fabric.
It's been unusable for a long time.
Lin Wei and her team tried several different materials.
The alloy plates are too heavy; I can't walk properly while wearing them.
Fireproof cloth does not insulate against heat; heat quickly penetrates it.
Even the toughest canvas in the base couldn't withstand the scorching heat.
The experiment failed time and time again.
The atmosphere in the research institute is becoming increasingly oppressive.
Exhaustion was etched on everyone's face.
Lin Wei sat at the table, looking at the glaring sunlight outside the window, feeling completely lost.
Is there really no other way?
"Sister Lin!"
Just then, Xiaoxue suddenly ran in.
She held a piece of metal in her hand, her face beaming with excitement.
Let's try this!
Lin Wei looked up.
Seeing the metal sheet in Xiaoxue's hand, I realized it was a boiling point alloy.
