1. Blue Star: The environment has collapsed, and mutated monsters roam everywhere. A highly advanced civilization known as the “Guardians” has arrived, using a “Light Curtain” to keep most monsters at bay and temporarily preserve human civilization, but resources are running low.
2. Exploration of Other Worlds: To obtain resources, the “Guardians” have opened five regions. Every day, “Explorers” are randomly selected from countries around the world to enter them. Each person can upload supplies once per day, and the “Guardians” will return them to their country with a random multiplier ranging from one hundred to ten thousand times.
