National Disaster: I Can Extract the Entries

When a disaster strikes, humans around the world are simultaneously transported to a different space called the "Blood Wasteland". Each person gets an "Awakening Stone" and a "Basic Thatched Cottage" as the initial stronghold. Monsters are rampant here and resources are scarce. Hunting monsters can obtain "source energy crystals" (general currency and upgrade materials). Collecting resources can upgrade buildings and production tools. All awakened people must communicate, trade, and form teams in the "regional channel". The initial coverage radius of the regional channel is 10 kilometers. When the number of survivors in an area falls below a certain threshold, the areas will "merge", ushering in stronger monsters and richer resources. Survivors can continue to grow stronger and eventually find the "Door of Return" to return to the earth transformed by the disaster.
