”Everything has two sides, just like light and darkness. Look at the green fairyland in front of you, doesn't it just form two sides with our human situation?"Before the 'doomsday' catastrophe, even if you were a long lived spirit or a powerful dragon family, you could only fall down and could not turn over a wave. The most ironic thing is that the source of this catastrophe is ourselves.Humans, of course, cannot escape the baptism of this catastrophe. Even if a small number of people have escaped the catastrophe, they cannot avoid the fact that 'human' has entered history.
