Let you be the wall-facer: you turn around and join the Three-Body Problem?

"You are such a spendthrift. How much does a GPS device cost? If you install it on all the buses, plus the maintenance costs of the GPS itself, the money you spend in a day will be more expensive than your life. I'm afraid the entire bus company will go bankrupt."

Wang Miao: ???

"No, brother, what kind of metaphor are you using? Is my life so worthless?"

Lin Xuan smiled.

"Do you know how they did it?"

Wang Miao shook his head.

"ZigBee technology, a very primitive short-distance communication technology."

"This thing has no other advantages, except that it has low power consumption and is very cost-effective. It turns itself off when not in use and only starts when activated, just like the sensor lights in the corridor."

Wang Miao was somewhat puzzled when he heard this.

"That's not right. The bus stop is at least a few kilometers away from the bus. I know ZigBee technology, but it has a short-range transmission range of only about 100 meters at most, which is not even as good as WiFi."

“That’s why their method is so ingenious.”

As Lin Xuan spoke, she rummaged through the pile of garbage beside her for a long time and took out an empty water bottle and a few small hairpins.

He arranged the hairpins in a row to simulate a bus stop, and used water bottles to simulate a moving bus.

Then he placed a magnet on the car and the small clip.

"See? Install a ZigBee module on the bus and one on the bus stop. When the bus arrives at the stop, the two ZigBee systems will activate each other."

Sure enough, when the empty water bottle moved to the first small clip station, the two magnets were instantly sucked together.

Wang Miao knew that Lin Xuan was simulating the reaction after the ZigBee module was activated.

"Look, you also said that the transmission distance of this thing is not as far as a WiFi, so we will directly change the transmission method from a transmission method that continuously sends signals to the main station to a device that only sends signals to the station."

"Whenever a car reaches the platform, it is always within 100 meters of the platform. At this time, the ZigBee module on the car and the ZigBee module on the platform will act like magnets and transmit an activation command to each other."

"Then once the platform is activated, the platform behind it can directly know where the car is now. This is the most efficient use of the lowest energy items, and I just modified their transmission method."

Wang Miao looked at the model in Lin Xuan's hand, and his eyes suddenly lit up.

"Wang Miao's shock value +100!"

"Fuck, Lin Xuan, you're such a genius!"

Chapter 51: The Prelude to the Great Depression

Lin Xuan's words gave Wang Miao a lot of inspiration. He immediately modified the model of the entire space elevator, changing the original whole elevator into countless sections.

The main function of a space elevator is to transport goods, transporting people or goods into space, saving the cost of launching rockets.

The original space elevator went straight up and down, rising from the ground to the top in an instant.

After Wang Miao's transformation, it now looks more like a real elevator.

Wang Miao layered it!

From the ground to low-Earth orbit is the first level. Press the switch on the ground, the elevator rises, and pulls people into space.

The second layer keeps the original design unchanged.

When you reach the third level, things will change.

At this point, it has actually exceeded the first cosmic speed, and the space elevator at least will not fall from the sky.

When the cargo passes through the second layer, the second layer is disconnected from the third layer, and the third layer begins to connect with the fourth layer, and this process continues until it reaches the synchronous orbit, which is the location of the space station.

This method actually poses a great safety hazard, because during the entire process of disconnecting the second and third floors and connecting the third and fourth floors, the two sections of the space elevator are only pulled by a few cables hanging in space to prevent their position and distance from shifting.

If there is any attack or something, the cable will be broken.

Then the entire space elevator will set sail directly and begin its endless interstellar journey.

Riding this thing into space is as exciting as a kid in the mountains climbing a cable car across a river.

I don't think the PDC will agree to let a living person try to sit on this thing in the short term.

However, this is the only way. With current human technology, we can only do this. When lighter materials are available in the future, these old space elevators may be eliminated.

Let’s put Wang Miao’s matter aside for now. A series of major events have occurred internationally in the past few days.

First of all, the precursor to the great low point has finally arrived.

"what is this?"

Zhang Xiang looked at what Ding Yi was holding in his hand. It looked a bit like banknotes, but not quite the same.

"Food coupons, you've never seen them before, have you?"

Ding Yi said with a smile.

"That's right. You weren't even born when this thing appeared. At that time, China was going through a period of madness. Food, drink and clothing were all very tight, and they could only be distributed according to need. Everyone got only a little, which was not enough. Ye Wenjie also chose to betray all of humanity at that time."

"Hey, this is a grain coupon, this is a cloth coupon, and this is a water coupon. If you go to the street to buy something now, you can't just take money, you have to use these coupons to pay together."

"So troublesome?"

"It would be nice to have it."

"I estimate that if the current situation continues, within a few years, we may not even be able to eat white flour. Let alone having tickets, you won't be able to buy anything."

Zhang Xiang looked at the pile of colorful tickets on the table and couldn't help but sigh.

"We were still happy when we were kids. We could buy whatever we wanted."

Although Lin Xuan had stopped Diaz in the first place, the Great Depression was inevitable. Even without Diaz, the development of industry would continue to deteriorate the earth's environment.

It is worth mentioning that, as Lin Xuan expected, some conflicts arose within the PDC due to the shortage of supplies.

The first to get into trouble were the Gauls. An unprecedented resistance movement broke out in their colonies in Africa.

The Gallics urgently dispatched ground troops to suppress the rebellion.

Then in the United States, Detroit suffered a terrorist attack by ETO. A building used to store PIA data was directly blown up by ETO, causing the deaths of about 8000 people.

At this time, the island country suddenly launched an attack and had a small-scale conflict with the Korean country, attempting to occupy the entire Korean Peninsula and form a unified Pacific front.

Since the island nation became a member of the PDC Group of Seven, its ambition has been growing. It is not just attacking Korea; it wants to unify the whole of Asia.

The result was naturally that they were beaten back by Chang Weisi's army, and had to pay a large sum of war damage compensation to Korea and China, which almost caused the island country's economy to regress to the shogunate era.

The sky cleared up, the rain stopped, and the island nation felt that it could do it again.

The entire human world is like a leaky boat, leaking water everywhere. The precursor to the great depression gives people a sense of impending storm.

Chapter 52 Orphanage

The accelerated evolution of the world pattern is not only reflected at the macro level, but this change will also be infinitely magnified in the micro level of personal life.

"Grass!"

Shi Qiang looked at the text message on his mobile phone and couldn't help cursing.

"These guys are really inhumane. My retirement age has been extended to 90?"

"What a joke! Does this mean I still have to go out and catch criminals when I'm 89?"

The retirement age has only increased in the last one or two years. Originally, people could retire at the age of 60 and go home to enjoy their retirement. However, due to the economic recession, the retirement age has continued to increase. In the sixth year of the crisis era, it increased to an exaggerated 6 years old.

Wang Miao smiled.

"That's nothing, look at your bank account."

Upon hearing this, Shi Qiang checked on his phone and was immediately shocked.

"What the hell? Storage fee, what is this?"

"It means exactly what it says. If you deposit money in a bank, you have to pay them a proportional amount. The interest rate is about the same as before, but it's negative now. The more money you deposit in the bank, the more you have to pay."

"It can still be like this!"

Shi Qiang was shocked.

In the past, I have only heard of interest increases when saving money, but why is it that now I have to lose money when saving money?

"You can also apply for a property freeze and transfer your current deposit to a fixed deposit. In this case, they will calculate the money based on the previous interest rate. However, this fixed deposit is calculated in units of 100 years, and it is still unknown whether you can get the money in the end. Who knows if the bank will still exist in a hundred years, and the entire human society may no longer exist."

Shi Qiang thought about it and quickly reacted.

"For the hibernators?"

"almost."

After several years of development, hibernation technology has become relatively mature.

Since the third year of the Crisis Era, hibernation technology has been put into use, but only short-term hibernation experiments were carried out at that time.

It was not until the fourth year of the Crisis Era that Zhang Beihai proposed the Future Reinforcement Plan, and hibernation technology was widely used in military strategy.

It is more common now. As long as you have money, you can apply for hibernation.

In fact, Wang Miao had discussed the issue of hibernation technology with Ding Yi before, and why it was so fast from experiment to application.

Both sides agreed that, just like cloning technology, it was previously intentionally restricted by the PDC, no, it was previously called the UN General Assembly.

Human society is an extremely complex society. People have hatred towards anyone who lives better than themselves.

I am afraid that my brother will suffer, and I am also afraid that my brother will drive a Land Rover.

The previous development of mankind was a process of continuous improvement, with technology advancing with each passing day and mankind being happy and fulfilled.

What do you mean by creating a hibernation technology?

He hibernates, so he can go to the future and live a good life, right? Then who would want to stay in the present and live a miserable life?

Furthermore, some diseases that are difficult to cure with modern medicine may be cured in the future.

This huge sense of imbalance will make the contradiction between the lower class and the upper class more intense.

But it’s different now. With the Three-Body Crisis, everyone will just think that those who choose to hibernate into the future are simply crazy.

I might as well live a carefree life while I can. After I die, I don’t care what happens.

Sure enough, in the end, just as Wang Miao and Ding Yi predicted, the ridicule of hibernators on the Internet has never stopped.

They call those who spend all their money and choose to hibernate "fools".

But the truth is that even if they spend all their money, they cannot buy a ticket to become a hibernator.

People are like this. They used to laugh at those who studied hard all the time, and now they laugh at these hibernators. This strange mentality has never changed from ancient times to the present.

The spread of the economic recession even affected Luo Ji to a certain extent.

In the Garden of Eden.

"Why don't you eat the food? I learned a few tricks from Zhang Xiang, and I thought you would like Huaxia's Chinese food."

Luo Ji looked at Zhuang Yan who had not touched his chopsticks.

"Do you want me to ask Kanter to change the menu? What do you want to eat? Liberian ham, grilled wagyu, or a French salad?"

Zhuang Yan shook her head.

"No, I don't have much appetite."

After the two of them sat in silence for a long time, Zhuang Yan finally mustered up the courage to ask the question in his mind.

"Luo, is the life we ​​are living now really part of the Wall-Facing Project?"

Luo Ji was stunned.

"Of course, as long as you and Minmin are happy, that's part of the plan."

Minmin refers to Luo Congmin, the daughter of Luo Ji and Zhuang Yan. Kant originally said that he could arrange the best hospital nearby for her, but Luo Ji and Zhuang Yan refused. They insisted on having their child born in China.

When Luo Ji said that, he looked into her eyes for a long time before Zhuang Yan continued to ask.

"But I'm not happy."

“All mankind is unhappy.”

"Have you seen, Luo? The situation outside is getting worse and worse. I saw on the news the other day that a two-year-old child was frozen to death in the snow at minus 30 degrees Celsius because his parents were unable to raise him. The child was about the same age as Minmin, but his life ended just like that."

"I haven't watched TV or watched the news since then. The stark contrast between our lives and the suffering of the outside world has made me feel very unhappy."
