Breath of the Ocean Planet

The land of the ocean planet is divided into two, with people living in areas of different oxygen levels having different skin colors. A-Xin lives in Zone G, A-Su belongs to Zone R, and A-Ruo is the only one who can freely cross between Zones G and R, as she is actually amphibious. The trio embarks on a series of adventures. In reality, the poisoning case of Zhongli Xiaoxin reveals a hidden abusive relationship between the two classes, amplifying human suspicion, panic-driven psychological states, and the sorrow of losing oneself. Breathing in the world should be equal. A-Xin, A-Su, and A-Ruo create a forest system, ultimately granting the planet's people the freedom to breathe.
