In the movie, researchers tackle taboo topics.

They use humans as material and study a variety of possibilities.

In some chilling experiments, the three plans were accidentally intertwined.

Yang Yiwu began to seriously consider whether he should not continue to let these children watch it.

Of course, the specific scenes of the experiment were not presented in a straightforward way, but judging from the light and shadow, the expressions of the experimenters, the final results, etc., it is easy for people to have many imaginations about it, and each imagination is enough to become a nightmare.

Yang Yiwu felt something was wrong.

Although he also admitted that at this critical moment of human survival, there would inevitably be some sacrifices and some things that went beyond past cognition and moral standards, but what he saw and heard before his eyes still exceeded his poor imagination.

The humans in the movie have given up all dignity, rules, morals, and humanity, and completely abandoned the social order that has been formed over tens of thousands of years, leaving only the purest animal nature, an image that they present in order to survive.

Such an image of Yang Yiwu may only be seen in some war documentaries or some insane cases.

It shows what humans will do when they lose their humanity.

Even more chilling is the scene where researchers who once said they were the hope of humanity and the last bastion are ruthlessly experimenting on their fellow human beings.

Yang Yiwu saw that the students subconsciously covered their eyes. Although these scenes were not too bloody or violent, they were filled with a cold and indifferent feeling.

Just like there are no ghosts in truly terrifying horror movies, movies that depict despair are not all about blood and flesh flying everywhere.

Yang Yiwu shuddered at the thought of the loss of humanity in such an apocalypse.

Compared to this kind of salvation, perhaps it would be more satisfying to just destroy everything.

If, before this, Yang Yiwu still watched this movie with the mentality of watching a special effects blockbuster to see how the heroes save the world, then at this moment, from now on, his mentality has completely changed.

Rather than a disaster film, this is more of an apocalypse.

It shows the psychological changes of human beings when facing doomsday. When giving up something, the living human beings are even more terrifying than those natural disasters.

Yang Yiwu could only watch helplessly as the people in the movie completed all of this step by step and stepped into the abyss.

Use body transformation technology to transform the monsters found in the wormhole, use consciousness uploading technology to infuse human thinking into those monsters. These crazy actions are completed little by little by those once proud scientists. Even the whole society begins to agree with these. People crazily want to become worms. They walk into the laboratory as if they are flocking to the promised land and crawl out as worms.

Yang Yiwu felt something rising in his throat, but in fact there was nothing there.

Even the wind and snow hitting the glass outside the window didn't seem so scary. What Yang Yiwu saw in the movie was the embodiment of despair.

Compared to the students who were shocked by these direct stimulations, Yang Yiwu thought of more.

Because, in this world, such behavior has happened before.

During wartime, people in certain countries carried out inhumane things with this kind of thinking, and in their opinion, this was an act of saving humanity.

History tells Yang Yiwu that what happened in the past will happen now and will happen in the future.

Even now, when faced with major disasters, the operations of some places make Yang Yiwu's blood pressure spike. It is hard to say whether these places can save more people while maintaining humanity in the real doomsday.

At this point in the film, Yang Yiwu can no longer see any reason for these humans to be saved.

They abandoned everything that made them human and became the Swarm.

Amid earthquakes, tsunamis, typhoons, and volcanic eruptions, the swarms of insects soar, resisting these natural disasters with their bodies that surpass humans. They pass through wormholes and go among the stars.

Only those humans who were infected with radiation, possessed superpowers but had a short lifespan, remained in the only remaining shelters, struggling to survive.

A scene that left a deep impression on Yang Yiwu appeared.

It was a city devastated by an earthquake. Above the devastated ruins, green sprouts were sprouting from the ground.

After unknown years of disaster, these geological changes finally subsided.

Humans, those mutated humans finally walked out of the shelter.

A sun rises, and humans walk alone in the desert.

At this moment, Yang Yiwu inexplicably thought of a sentence he had seen on a social networking site before.

[Life will always find a way].

Over billions of years, this planet has experienced many more tragic mass extinction events, and countless creatures have disappeared forever in the long river of history.

But every time, after extinction, some life always survives and thrives on the planet again.

Yang Yiwu saw a team exploring the desert. They were trying to find a solution to the insect swarm problem.

Beyond the dunes, the team saw a group of buildings.

When he saw the building, Yang Yiwu couldn't help but tremble.

Because that is the future city where those scientists live.

In this city, robots are still cleaning the streets and the buildings seem to be well preserved.

The explorers came to the front building, pushed the door open, and saw a scene of lush greenery.

A young girl is sleeping soundly surrounded by animals, and she is the artificial intelligence robot left behind by the man in the previous movie.

For who knows how many years, she has been waiting here, waiting for humans.

In an instant, the past and the present, survival and destruction, the humans of the old era and the humans of the new era were connected at this moment.

The girl woke up and noticed the explorers. She smiled the same smile she had a hundred years ago.

"Welcome back."

The girl said, and her voice seemed to travel through time, from the old era to the new era.

A butterfly fluttered past her and flew towards the sunshine.

The movie ends.

It is difficult for Yang Yiwu to describe his feelings.

In just two hours, he witnessed the ugliest things in humanity, but also the most precious things in human nature.

The scene at the end of the world was like the darkest night, and he could only yell and curse helplessly.

Even though humans seem to have survived in the ending, the invasion of insects and their short lifespan still make people see no hope.

Perhaps, only when he saw the girl robot did Yang Yiwu feel that there are some things in this world that will never change.

He saw his students crying.

These students, who lacked experience, might have shed tears because of witnessing the ending, but Yang Yiwu could not cry.

He felt only deep despair.

Just like the wind and snow outside, it never stops.
