Global Hypoxia

Gu Feng lives in a gray age with declining oxygen. Mechanical giants fight dinosaurs at the border, lasers of destruction bloom in ruined cities, and the bloody setting sun envelopes the young people who have grown up in this generation. As a descendant of aliens, he just wanted to live his life quietly on earth, until that day, two mysterious lights came to the door. "Take us to save the world!" The white light said. "But what's the use of you?" Gu Feng put down the Feizhai Happy Water in his hand. "I can make everyone forgive you!" The green light showed a meaningful smile.
