"He is dying, it is mourning."
Nuclear pollution, destruction of the atmosphere, melting glaciers, unknown viruses in the universe and other hazards have swept across the entire Blue Star. Creatures are deforming, and some humans are infected with unknown diseases and become unspeakable monsters. Human space is shrinking, but they still struggle against nature.
Feng Youyin has known its pain since he could remember it. This blue planet gave birth to him, and he became the only successor of this planet.
Purpose: Protecting the environment is everyone's responsibility.
