What are the details in "The Three-Body Problem" that are horrifying to think about?

The whole "Three Body" is scary enough without even thinking about it... The dark forest... We humans are always ready to develop and develop, but we are cleared by aliens with a map cannon...

Even if we escape the fate of total annihilation, the earth occupied by aliens will still be a hell-like existence. It is not our home at all. The moral sense and world view of aliens are incomprehensible to humans.

"What about the food?! Where does the food come from?!" Someone else shouted, their fear of Tomoko had disappeared, leaving only extreme despair. Tomoko looked around at everyone in the hall, "Food? Isn’t this all food? Everyone, look around you. It’s all food, living food.” Tomoko said this very calmly.

Even if we don’t talk about external competition, there are still many educational things in our daily life. For example, Cheng Xin when she first appeared in the second film was also an outstanding warrior, and she could do anything for the future of the earth. For example, she was the only one who abandoned the bottom-line moral sense of human nature and made the decision to "give away only her brain" in an extraordinary period.

However, once she got the love of Yun Tianming, the status and wealth that Yun Tianming brought to her star, and the status of the sword holder, she no longer felt a huge sense of oppression. She immediately I just know how to follow my heart, I don’t want to make any difficult decisions, and I don’t want to be stained with any sins.

At the end of the novel, the earth, and even the universe, died because of her indecision, which of course would not be the case in reality.

However, living in sorrow and dying in happiness may be something that each of us needs to be wary of!
