Sky Curtain: The Darwin Incident at the outset, the Declaration of the People's League

It can monitor any corner of the earth and eavesdrop on anyone's conversation.

Every scientific experiment, every secret meeting, and every covert act of resistance by humanity was conducted right under the noses of the Trisolarans.

Humans have become invisible.

This is the first blow the Trisolarans have dealt to humanity—locking down their technology, ensuring that humanity can never surpass them.

But humanity is not going to sit idly by and wait to perish.

Humanity soon realized that the Trisolarans had a fatal weakness—they could not see through human thought.

The Trisolarans' minds are transparent; their communication is completely open and honest, and what they say is everything they think.

Therefore, they cannot comprehend "deception"—an instinct deeply ingrained in human society that is completely absent in the Trisolaran civilization.

Humanity has decided to exploit this weakness.

An ultimate strategy codenamed "Project Wallfacer" has been launched.

Four "Wallfacers" were selected and granted the greatest authority in the history of human civilization: the ability to mobilize any resource, implement any plan, and without having to explain it to anyone.

All they needed to do was deceive the Trisolarans with illusions, carving out a path for humanity to survive in an absolutely transparent world.

Among the four wall-facers, there is one who is the most inconspicuous.

In the image, a cynical young scholar leans back in his chair, his eyes filled with disdain for the world.

Luo Ji, a cynical and unproductive ordinary scholar.

He was the only human designated to be killed by the Trisolaran world.

[ETO's assassination attempt ironically propelled him into the position of a Wallfacer.]

At first, Luo Ji only wanted to escape.

He used his privileges to live a secluded life by a lake in Switzerland, with his lover, as if the end of the world would never come.

[Until his lover entered a frozen state, preparing to travel through time to the future.]

Luo Ji has nowhere to retreat, nowhere to avoid.

One night, he began to think.

He recalled a few words Ye Wenjie had said to him many years ago.

At the time, he thought it was just idle chatter between elders and juniors, and completely meaningless.

Now that I think about it...

"Cosmic sociology...two axioms: First, survival is the primary need of civilization. Second, civilization continues to grow and expand, but the total amount of matter in the universe remains constant."

"There are two more concepts: the chain of suspicion and the technological explosion."

Following these two axioms, Luo Ji, through the chilling logic, touched upon the cruelest truth of the universe.

The Dark Forest Theory

Only then did he understand why he was the target of the Trisolarans' hunt.

After his epiphany, he began to take action.

In the scene, Luo Ji stands in an empty field, facing the starry sky.

He held a gun to his temple.

Luo Ji has found a weapon to fight the Trisolarans.

The Dark Forest Theory

He demonstrated his power to the Trisolarans by hurling insults at them—broadcasting the coordinates of a star to the universe via the sun.

Then, through the Sophon, he issued his ultimatum to the Trisolaran world.

"Now, I, Luo Ji, am speaking to the Trisolaran world."

He gambled with the lives of all humanity to establish a terrifying balance.

If the Trisolaran fleet dares to continue advancing, he will broadcast the coordinates of the Trisolaran world to the entire universe.

At that time, a more advanced civilization will intervene and wipe the Trisolaran system, along with its fleet, away like dust.

Of course, Earth's coordinates will also be revealed.

This is the Dark Forest's deterrent—it's a matter of mutual destruction.

[Dare to come closer? Then we'll die together!]

It can be said that Luo Ji saved humanity.

Unfortunately, humanity is not grateful to Luo Ji.

【why? 】

Because the world always operates in such a peculiar way.

He held the switch of deterrence, protecting humanity for more than half a century.

Gradually, he grew into an old man, a lonely night watchman sitting in the darkness, a weapon in his hand.

The Trisolarans' attack could strike at any moment; he must be ready at any time to press the button that destroys both worlds.

He did only one thing.

[Living, holding on]

But humanity ultimately failed to pass on this determination.

Decades later, humanity elected a new "Swordholder".

Her name is Cheng Xin, a woman known for her love and kindness.

In the scene, a gentle woman walks to the position of the swordsman.

[In the face of the sudden attack launched by the Trisolarans, she hesitated when confronted with a critical choice.]

She failed to press the button that would destroy two worlds and save human civilization.

Deterrence failed.

The Trisolaran droplet weapon instantly destroyed all of humanity's gravitational wave transmitters.

Humanity's sword has broken.

The Dark Forest Deterrence Era Ends, the Trisolaran Invasion Era Begins

Humans were relocated to Australia, and civilization suffered an unprecedented catastrophe.

Just when the Trisolarans seemed to have victory in their grasp, fate took another turn.

The human warship "Blue Space," which was reportedly on the run, did not actually escape.

They exploited the Trisolarans' weakness of transparent thinking, secretly establishing a transmitter capable of broadcasting the coordinates of the Trisolaran world.

As the Trisolaran fleet approached Earth, preparing to take it over, the "Blue Space" broadcast the coordinates of the Trisolaran system into space.

Less than a year later, the apocalypse arrived.

The Trisolaran system was completely destroyed by an attack from unknown "light particles".

A star was pierced through, and the Trisolaran world was reduced to nothingness in the flames.

The Second Fleet of the Trisolarans, having escaped the catastrophe, became orphans wandering the universe.

The Trisolaran civilization was nearly wiped out.

Before humanity could even celebrate, an even greater despair loomed over them.

Are there other hunters in the universe?

The coordinates of the Three-Body world have been exposed—so, how far away can humanity's coordinates be?

[Shortly afterward, the solar system was marked by an unknown "observer"]

In the scene, an entity far beyond human comprehension—a cosmic cleaner known as the "Singer"—is routinely cleaning up exposed targets in the dark forest.

He opened the warehouse and casually took out an old-fashioned weapon—a two-dimensional foil.

One of the most terrifying ways to destroy things in the universe.

The three-dimensional space that is touched will be irreversibly "two-dimensionalized".

Stars, planets, life, civilization—everything was compressed into a flat plane.

[A true game-changer!]

The solar system has begun its fall.

Jupiter was flattened, transforming into a magnificent vortex on a two-dimensional plane.

Saturn was flattened, and its rings spread out in a two-dimensional plane.

The Earth is flattened—oceans, continents, and clouds are spread out on a two-dimensional plane, all the relics of human civilization, all history and memory, all love and hate are compressed into a picture with no thickness.

Luo Ji, humanity's last Wallfacer, was reduced to two dimensions along with the solar system—in his final moments, he found only peace.

He protected humanity for more than half a century, and even in his final moments, he remained standing.

Human civilization is almost extinct.

But the story isn't over yet.

Cheng Xin and her friend Ai AA escaped the solar system aboard the "Star Ring," the only light-speed spaceship equipped with a warp drive engine.

They drifted through the universe, witnessing its vastness and desolation.

They encountered a mysterious civilization called the "Zeroers"—a super-civilization attempting to reboot the entire universe.

The "Zero Returnists" believe that the universe is dying, its dimensions are folding, and its matter is being consumed by the war in the Dark Forest.

The only way to save the universe is to return all the stolen matter—to restore the universe's mass to a level sufficient to trigger a new Big Bang.

Cheng Xin and Ai AA made the final decision—they launched their spaceship and all the supplies it carried into the "return movement" of space.

They didn't know if it would work; they just felt that something should be done.

The universe has existed for countless billions of years.

At the edge of the universe, a new Big Bang is brewing.
