In the wasteland of the apocalyptic plane, there is a weak green sapling, and under the tree lies a sleeping girl.
Countless fireflies emitted light day and night, using their last bit of soul fire to protect them. Every bit of fluorescence, every flash of light and dark, seems to tell the most persistent beliefs and deepest memories in a person's soul! "Live on, live on!" The cycle repeats!
When the last bit of fluorescence dissipated and the saplings were about to wither, the will of the plane let out a sigh and used up its last strength to make a deal with the mysterious man. From then on, the tree of life and the only survivor of the apocalyptic plane set foot on the infinite world, using equal transactions to inherit civilization and explore the end of life!
