A "red mist" of unknown origin swept across the world, and civilization was reduced to ruins amid roaring monsters and silent silence. Former search and rescue team member Lu Yuan woke up in the apocalypse. The only thing that kept him alive was finding his sister, Lu Yao, who was studying in college in another city.
Relying on the mysterious "system" awakened in his mind that could warn of danger, Lu Yuan embarked on a journey across thousands of miles of wasteland to find his family. He will travel through the dead city occupied by "abnormalities", deal with the hearts of people who are more unpredictable than monsters, and use all means to survive.
When the truth of the world was revealed layer by layer in blood and fire, he discovered that this doomsday might not be a natural disaster. And the system in his mind seems to hide secrets related to the ultimate fate of mankind. Before the dawn is completely extinguished, he must become the spark that ignites hope, even if it burns himself to ashes.
