Wu Hao is a girl born in the 1990s in the 21st century. She is studying for a doctorate in philosophy at a university in the United States. In order to seek the meaning of life, she attempts to explain three major philosophical propositions - Who am I? Where do I come from? Where am I going? , With the help of scientists, traveled to a fantasy world, and after experiencing the three poisons and seven sufferings of life (three poisons: resentment, anger, and ignorance; seven sufferings: birth, old age, illness, and death, love and hate, lost, and not obtained), gradually understood the meaning of life, and also developed his own set of ideological systems about the nature of human beings.
"I am Wu Hao, I have a heart, I have a heart, you, why don't you believe me?!"
"Who am I?, Where do I come from?, Where am I going?, Why do I feel a heavy emptiness that is engulfing me like a flood? Anyway, I am going to die, everyone is going to die, why am I still alive, and what is the meaning of my life?! "Empty eyes, face full of tears, dying heart, limp body, trembling hands touching Wu Ling's purple lips, even you who are in charge of life and death are dead, even you, the only one in the world who protects and loves me, is dead. How do you want me to live in this fantasy world?
"Ah Ma, don't cry. The sun will always set, but you still have to cherish the day. People will always die, but you still have to live well."
"Nao'er, don't be afraid. The sun is gone, but there is still the moon. The moon is gone, and there are stars. The stars are gone, and there are fireflies. The fireflies are gone, and there are still my eyes."
