The Apocalypse of Suffocation: I'm the Only One Who Doesn't Worry About Oxygen

After falling in love, Lu Ran was confused and confused. When he woke up, he found that he had traveled to a parallel world - Blue Star. In the last days, Lu Ran didn't worry about oxygen, he only worried about the high demand of S-class goddesses. This place has experienced a "catastrophe", the global oxygen content has plummeted, and every breath is a luxury. Human beings can only huddle in unfinished buildings and linger on. The high temperature radiation on the surface of the earth is deadly, the underground tunnels are crawling with mutated monsters, and the giant Titans that block the sky are wandering in the sky. Fortunately, Lu Ran awakened the "atmospheric adaptation system" and was able to see the distribution of oxygen in the air! When others are suffocating and struggling, he can find oxygen enrichment points; when monsters hunt humans, he can see through their breathing weaknesses; when tyrants monopolize water sources, he can discover underground treasures of living water! From the coolie on the ground floor of an unfinished building to the new king who controls the water source. From a lone traveler to a leader who established a sanctuary. In this suffocating world, Lu Ran must use his own abilities to stir up the order of the entire apocalypse! Because here, to control oxygen is to control life and death!
