Countdown: Humanity's struggle to survive against yesterday

Chapter 85 Research on Unconventional Sleep

Jiang Ning did not assign Sun Fumin any specific tasks, but simply allowed him to act according to his own abilities.

After hearing this, Sun Fumin grinned and didn't seem to mind.

This time, he had already made up his mind. While others could take turns resting, he insisted on staying by Jiang Ning's side for two or three months to see what would happen if he didn't follow along.

This is the problem we faced during our last break.

Everyone stayed in Jiangning for a month before leaving. On the first day of experiencing the world's reversal, they felt dizzy and had nosebleeds, and felt a great burden.

Sun Fumin brought up this idea during that video conference, but the others did not agree.

However, Sun Fumin had already made a decision in secret, believing that this was also a kind of scientific experiment.

Rather than looking for someone else, we should just go with him.

Since he's Xiao Ning's childhood friend, he's practically one of their own. If even one of their own isn't willing to take the lead and always asks others for help, it will only make it harder for Xiao Ning to extricate himself from the situation later.

In layman's terms, "He who eats another's food is bound to be bound by his kindness, and he who takes another's money is bound to be bound by his kindness."

Jiang Ning continued assigning tasks, and finally looked at Chang Niankong.

"Master Chang, the first step of the plan doesn't require your involvement yet. Like Sun Fumin, you can start by doing what you can!"

"clear!"

Chang Niankong nodded.

In this plan, his contribution is needed in the second and fourth steps. When the samples are selected, he needs to communicate with Jiang Ning remotely, memorize the sample names, and recite them to Jiang Ning one by one.

This allows Jiang Ning to know about changes in external data even while inside the mysterious space.

Seeing that Su Mian, Lu Xue, and Zhang Jimin were all in their positions, Jiang Ning lay down on a recliner and entered the mysterious space.

One minute later, the three of them started to activate all of Luoshu's computing power as planned.

In less than thirty seconds, the colors on the three computers and the screens on all four sides of the underground level changed.

Street scenes, rooms, and areas flashed across the surrounding screens like a slideshow.

There is a saying in Buddhist scriptures: "One flower, one world."

On the electronic screens surrounding us, each screen seems to be performing this sentence, showing all kinds of life, flowers, trees, tall buildings, cars, birds, and insects, constantly changing in an instant.

The surrounding images were like a movie sped up a hundred times, and the human vision simply couldn't keep up. Sun Fumin, Chang Niankong, and all the staff who had stopped working in the hall felt dizzy and lightheaded after watching for only a short while.

A knowledgeable middle-aged staff member, witnessing this, exclaimed in surprise, "Even the radio signals and radar have been activated..."

"What do you mean?" Sun Fumin, with his sharp ears, heard this and quickly stepped forward to ask.

Upon approaching, Sun Fumin saw the name on the other person's name tag: "Sun Fanzhi!"

"Wow, it's still our family name."

"Teacher Sun, what did you just mean? Didn't Xiao Ning say we were only counting who was sleeping and who was awake? Why are the wireless signal and radar activated as well?"

Sun Fanzhi knew Sun Fumin, so he was considered a minor celebrity.

I heard some time ago that he went to see Political Commissar Zhou out of boredom and unexpectedly discovered that even against the backdrop of a great regression, humanity can still cultivate a new temperament, which greatly surprised the entire scientific community.

The two had never spoken before, but seeing Sun Fumin's question, they smiled and asked in return, "Aren't you from the Returning Heaven Group conducting sleep testing surveys?"

"Yes!" Sun Fumin nodded.

"Do you even know what people used to rely on for sleep monitoring?"

"Is that even a question?"

Sun Fumin pointed to a bracelet on Chang Niankong's wrist, "Isn't it a sleep tracker?"

"The core working principle of sleep trackers is 'estimation,' not calculation. In addition to trackers, there are actually many other professional methods in medicine and psychology for sleep research."

"For example..."

Sun Fumin, who had nothing else to do at the moment, quickly pulled Sun Fanzhi aside and invited several other researchers nearby who were unable to work to sit together.

It looked more like a tea party.

Sun Fanzhi did not object to this, but simply smiled faintly.

"Electroencephalograms, electrooculograms, heart rate monitoring, respiration monitoring, and blood oxygenation monitoring are all authoritative sleep tests."

"But what does this have to do with the radio and radar you mentioned?"

"All of these are called contact-based sleep monitoring devices. In addition, there are non-contact environmental sensor devices."

Seeing that Sun Fumin was still completely confused, Sun Fanzhi couldn't help but mutter to himself, "Why does the Huitian Group recruit just anyone?"

This shows absolutely no scientific literacy!

But as an adult, you certainly wouldn't ask or inquire about it.

So, based on the fact that they shared the same surname and were colleagues, Sun Fanzhi decided to give this person a proper talk.

"Non-contact environmental sensor devices can be placed indoors and primarily extract sleep information by monitoring body movement and breathing activities. Common types include camera-based devices, devices based on radio signals and radar, and devices based on infrared technology."

"Oh! Now I understand!"

Sun Fumin took out the cigarettes he had brought from his hometown and offered them to everyone. Finding that no one was smoking them, he put one in his mouth. Seeing that several women were staring at him, he finally decided not to smoke it.

"Teacher Sun, can I understand that Luo Shu not only forcibly took over all the cameras, but even controlled the home Wi-Fi? I remember Wi-Fi also transmits signals, right?"

Upon hearing this, Sun Fanzhi nodded in surprise. He hadn't expected that Sun Fumin wasn't completely ignorant; he could apply what he learned to other situations.

"Wireless radar can be used for object detection and ranging. Pulse-based ultra-wideband radar can measure minute movements with high precision, thereby achieving accurate monitoring of respiratory rate. In fact, if you ask Team Leader Jiang, he will know that WIFI has long been widely used for monitoring vital signs during sleep."

This is because breathing and heartbeat cause deformation of the abdomen and chest, which alters the propagation path of WiFi signals, and WiFi signal status information can record these signals.

Many wealthy families have already installed these complete health early warning systems. Based on this technology, if an elderly person faints or experiences a sudden illness, the home health AI can directly issue an alarm and call for help.

"Oh!" Sun Fumin exclaimed in surprise, feeling greatly enlightened. He thought to himself, "Once Old Zhang is done with his work, I must ask him properly, is it really that amazing?"

Seeing that there was nothing to do for the time being and that all the computing power had been used by the Huitian Group, the other staff members also gradually gathered around.

A few people went to assist Su Mian, Lu Xue, and Zhang Jimin, but most of them stayed around Sun Fumin.

Before Sun Fumin could ask any more questions, the elites from all walks of life began to excitedly analyze the situation themselves.

Some even suggested that a program should be immediately developed to use mobile phone transmitters to collect everyone's information.

There are also smart refrigerators, ceiling lights, toilets, and other household appliances. Anything with a controller and sensors can have a signal cracker programmed to make it easier to collect information.

Sun Fumin and Chang Niankong were increasingly shocked as they listened. They could only conclude that when it came to dirtiness and audacity, these scientists were the best.

For Sun Fumin, cracking the cameras and surveillance equipment and being able to visually observe who was sleeping and who was awake was already considered high-tech.

This group of people has such wild imaginations, from bedding to kitchen and toilet supplies, and they get more and more excited as they talk.

Some have suggested using navigation satellites for a comprehensive, blanket scan, which would solve the problem of some mountainous areas lacking cameras.

Towards the end of the discussion, the topic shifted to how to increase the coverage of Skynet. Without any privacy or moral repercussions, everyone uttered astonishing remarks, which was truly eye-opening.

Two hours passed quickly.

Jiang Ning did not choose to leave the mysterious space, but instead stayed inside.

Su Mian and the other two began to compile the information.
