I Stack Attributes in the Apocalypse

"The tower is out. The end is now." The mysterious tower in the city, the endless demons coming out of the mist. This was the end of humanity. But not the end of Lu Ming. ... When doomsday descended, Lu Ming awakened the attribute panel. Push-ups increased strength. Deep squats strengthened physical strength. Running improved agility. Fighting, shooting, parkour, fitness and so on and so forth... were all digitized. He could level up upon reaching a certain level. When others were desperately fighting, all I had to do was stack my attributes until I reached the highest level. When I reach the highest level, I'll write my own history. Lu Ming: I am busy now. Maybe later.
