When I Am the Only Male Creature Left in the World

[Micro-apocalypse + no heroine + survival] Never look at the moon. Wu Yulong received a text message that night. He who didn't believe in evil insisted on seeing it. I didn't expect to miss it when I fell asleep. It is precisely because of this that he escaped. I was imprisoned by my aunt for two years just for smoking a cigarette. After seven hundred and thirty days of devastation. When his life was in danger, the system finally awakened. Two years of imprisonment in the dark have left him with information bias. I have no idea what the outside world is like. I didn't know that energy couldn't be stored. Not to mention that he was the only man left in the world! What will you encounter in the future? A cannibal tribe? Unknown creature? Does he have to rely on him alone to carry on the family lineage all over the world? He is the only weak man left and clings to the strong to survive. Or use the system to strengthen yourself and trample everything under your feet? How to choose the problems you face? All this is destined. Man still conquers nature!
