December 21, 2012, was the doomsday predicted in the Mayan literature, but on that day, there were no meteorites, tsunamis, earthquakes, volcanic eruptions... But only mutations in human genes.
Mu Yi, a girl who is only in her first year of high school, is unfortunately a mutant of this genetic mutation. When she woke up, she couldn't look directly at her miserable appearance.
This world is no longer the original world, it has become a hell of groups of walking dead. Mu Yi was undoubtedly lucky in this mutation. She still retained her original human consciousness, but was this really a blessing in disguise? Are genes really that prone to mutation? Is this really the end of the world, or is it a huge conspiracy?
