Starting as a Wallfacer, his defection to the Three-Body Problem shocked the world.

Lin Xuan's words gave Wang Miao a lot of inspiration. He immediately modified the model of the entire space elevator, changing what was originally a single elevator into countless segments.

The primary function of a space elevator is to transport goods, taking people or cargo into space, thus eliminating the cost of launching rockets.

The original space elevator was vertical, rising straight up and down in one go from the ground to the top.

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

Wang Miao divided it into layers!

From the ground to near-Earth orbit, that's the first level. Press a switch on the ground, and the elevator goes up, taking people into space.

The second layer, on the other hand, retains the original design.

When we reach the third level, things will change.

At this point, the space elevator has already exceeded the first cosmic velocity, so it will at least not fall from the sky.

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

This method actually has significant safety risks, because during the entire process of disconnecting from the second and third floors and connecting the third and fourth floors, the two space elevators are only held together by a few cables suspended in space to prevent their positions from shifting.

In case of an attack or something, the cable will be broken.

Then the entire space elevator will set sail and embark on its endless interstellar journey.

Taking a ride on this thing to space is as thrilling as a child in the mountains climbing a cable car to cross a river.

It is estimated that the PDC will not agree to allow living people to try sitting on this thing in the short term.

However, this is the only option available at present. With current human technology, this is the best we can do. Perhaps in the future, when lighter materials are available, these old space elevators will be phased out.

Putting Wang Miao's matter aside for now, a series of major events have occurred internationally in the past few days.

First, the harbingers of a major downturn have finally arrived.

"what is this?"

Zhang Xiang looked at what Ding Yi was holding; it looked a bit like banknotes, but not quite the same.

"Grain 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. Back then, China went through a crazy era. Food, drink, and clothing were scarce, so everything was distributed according to need. Each person only received a tiny amount, which was far from enough. It was during that time that Ye Wenjie chose to betray all of humanity."

"Here, this is a grain coupon, this is a cloth coupon, and this is a water coupon. When you go out to buy things now, you can't just use cash; you need to use these coupons for payment."

"So troublesome?"

"It would be nice to have it."

"I estimate that if things continue like this, in a few years we might not even be able to afford white flour anymore. Forget about having ration coupons, you won't be able to buy anything."

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

"We were so much happier when we were kids, we could buy whatever we wanted."

Although Lin Xuan stopped Radiiaz immediately, the Great Depression was inevitable. Even without Radiiaz, industrial development would have continued to worsen the Earth's environment.

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

The first to run into trouble were the French, who launched an unprecedentedly large resistance movement in their colonies in Africa.

France urgently dispatched ground troops to suppress the unrest.

Then, back in the United States, Detroit was attacked by the ETO. A building used to store PIA data was directly destroyed by the ETO, resulting in the deaths of approximately 8000 people.

At this time, the island nation also suddenly launched an attack, engaging in small-scale conflicts with South Korea, attempting to occupy the entire Korean Peninsula and form a unified Pacific front.

Since becoming a member of the G7, the island nation's ambitions have been growing. It's not just attacking South Korea; it wants to unify the whole of Asia.

As a result, Chang Weisi led his army to drive them back, and they had to pay a large sum of war damages to South Korea and China, almost causing the island nation's economy to regress to the Shogunate era.

The sky cleared, the rain stopped, and the island nation felt confident again.

The entire human world is like a ship with a leaky bottom, seeping water everywhere. The harbingers of a great downturn give people a sense of impending doom.
