I Deliver Oxygen at the End of the World

In 2099, a meteorite hit the Blue Star, causing an extreme lack of oxygen. As expected, a company called "Fushou Technology" had developed high-end oxygen production equipment two years ago and had close ties with foreign companies. The entire city is "controlled" by this company. No oxygen is equivalent to death. Fortunately, I am reborn and I am no longer at the mercy of others!
