In the Last Days, I Just Want to Be a Civilized Person!

[Survival in the end of the world + egoism + decisive killing + new era + not the Virgin + single female protagonist] The crimson sun rises, and the red rain of death falls! On February 2, 2041, in the Civilization Era, a crimson sun rose. Those who received the crimson light strengthened their bodies and became strengthened ones. Three days later, red rain fell, and the air of death spread all over the world. The road to strengthening is filled with death energy, known to the world as the Crimson Era! Mo Bufan took his wife and was reborn half an hour before the era restarted. The death energy that everyone fears is the best resource for him. Where others strive to improve their realm, he ranks highest and has the strongest combat power. Mo Bufan came back from rebirth, gained the power to swallow death energy, and killed his enemies in his previous life, in the era of cholera and crimson. Everyone says that in the last days, human nature is terrible! But what's worse... "You didn't even ask and just killed him? That's boring!" Someone screamed crazily before dying. "You crazy person!" "What I'm saying is, I'm letting you get out of trouble painlessly in advance!" Mo Bufan was a little speechless. In fact, he wanted to be a civilized person in the end of the world! After all, he kills people quickly, artistically, and... Civilized!
