Waking up, billions of people are scattered across various sky islands. Each person starts with a fishing rod, able to fish for supplies from the cloud clusters. While everyone is waiting for supplies in the cloud clusters to bite the hook, Yun Fan uses the replication system to place a circle of fishing rods around the sky island. When others enter the agricultural civilization, Yun Fan's aerial caravan has already embarked on a long voyage. When humanity prepares to rebuild civilization, Yun Fan's extraterrestrial base has been officially established and has begun looking out towards the endless river of stars.
