In the near future, a technology company called "Eternal Echo" has developed revolutionary technology - "Consciousness Anchor". This technology allows humans to digitally back up their complete consciousness (including memory, personality, and emotions) and upload it to the global super network "Eternal Domain". People can "live forever" here, and can even return to the real world through customized "carriers" (bionic humans). Death is no longer an end, but a reversible data migration.
