1. Everything will end one day, the sun and the universe will die one day. Why do humans alone think that they should be immortal? I tell you, the world is currently paranoid and foolishly fighting a hopeless battle. Regarding the three-body crisis, we can completely change our way of thinking. Throw away all worries, not just those related to the crisis, but all worries before the crisis, and enjoy life to the fullest with the time you have left.

2. Do you know what the Wall-Facing Project is? Its success depends on its incomprehensibility. The Wall-Facing Project The highest state is that no one on Earth or the Trisolaran World can understand it except the Wallfacer himself.

3. Do you know what is the highest expression of valuing a race or civilization? Killing them all is the highest priority for a civilization.

4. The truth is simple, it is this kind of thing, which makes you wonder what you thought about yourself after hearing it Why can't I find it?

5. Now we need to find two axioms for the civilization of the universe: 1. Survival is the first priority of civilization. One need. 2. Civilization continues to grow and expand, but the total amount of matter in the universe remains unchanged.

6. Exponents are the devil in mathematics. If there is a bacteria in the sea that is invisible to the naked eye, , divides once every half hour, and given enough nutrients, its offspring can fill all the earth's oceans in a few days.

7. As long as the technology mastered by civilization exceeds a certain threshold, the expansion of life in the universe will be very difficult. Horrible. For example, at the current speed of human navigation, Earth civilization will crowd the entire galaxy in one million years. One million years is only a short time on the scale of the universe.

8. Words such as good and evil are not rigorous in science, so they need to be treated The meaning is limited: goodwill means not taking the initiative to attack and destroy other civilizations, while bad faith means the opposite.

9. Human beings are the same species, have similar cultures, and live in the same interdependent ecology Circle, close distance, in such an environment, the chain of suspicion can only extend one to two levels before being eliminated by communication. But in space, the chain of suspicion can extend very long, and things like the Dark Battle have already happened before being resolved by communication.

10. My heart is already a pile of burned ashes, and I have no ability to be angry.

——Liu Cixin's "Three-body 2: Dark Forest" (Luo Ji)

11. Now, I will stop my heart from beating, and at the same time, I will become two The greatest criminal the world has ever known. I deeply apologize to both civilizations for the crimes I committed, but will not repent because this is the only option. I know Tomoko is around, but you never pay attention to the call of mankind. Silence is the greatest contempt. We have endured this contempt for two centuries. Now, if you want, you can continue to remain silent. I only give you Thirty seconds.

——Liu Cixin's "Three-body 2: Dark Forest" (Luo Ji)

12. Human beings have not been able to clearly see the dark forest state of the universe, not because of the lack of civilizational evolution. Maturity lacks cosmic consciousness, but because humans have love.

——Liu Cixin's "Three-body 2: Dark Forest" (Luo Ji)

13. I know that there is love in the Three-body world, but it is not conducive to the overall survival of civilization. It is suppressed in the bud, but the vitality of this bud is very tenacious and will grow in some individuals.

14. I have a dream. Maybe one day, bright sunshine can shine into the dark forest. At this time, the sun here is setting, and now only the top of the mountain is exposed, like a bright gem inlaid on the top of the mountain. The child has run away, bathing in the golden sunset together with the grass.
