The world has experienced an unknown apocalyptic disaster (the "Great Silence") and the old civilization collapsed.
Lin Xuan (modern name) was actually a rich kid named "Chen Xing" who was terminally ill 100 years ago. He was cryopreserved by his father through the "Seed Project" until he woke up a hundred years later in the body of a poor boy named "Atu".
· "Grandma": On the surface, she is Ah Tu's grandmother, but in fact she is the advanced artificial intelligence (AI) created by her father, codenamed "Guardian". For a hundred years, she has been protecting the protagonist's body and simulating her family environment, waiting for the opportunity to wake up.
· Dr. Chen, doomsday prophet and founder of the "Seed Project",
· All forces including the "Renaissance Army" that rules the new world, the "Truth Society" that worships old technology, and the refugees struggling to survive, are all eyeing the "seeds".
Traveling through the old world, Lin Xuan will start the road to save the world.
