The researcher had previously studied birds at the Bird Diversity Institute, but when the research results
were no longer available due to the extinction of birds, Echo points, a cloud city contribution system,
decreased and were evicted to lower floors of residence. Also, due to the abolition of the research
institute where he was working, he was assigned to a new research department.
The name of the research department is "Drone Healthcare and Resources Lab" Here, drones are created that
technically mimic the impact of extinct birds on the global environment A researcher who has come to study
technology to create and repair “bird mimicking robots” feels deeply skeptical.
