I Awakened the Swordsman in the End of the World

When the end of the world comes, the human heart is scarier than anything else. Maybe the food you just got became the food in someone else's belly in the blink of an eye, and you can only become a corpse. Maybe you just saved a girl, and she knocked you down with a knife from behind. How to survive in the apocalypse? There is no Virgin Mary or heroine in this book. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
