Mysterious Recovery: Science First

Hope in this era is a river that has long since dried up, leaving only scattered gravel in a lifeless riverbed. Fear is spreading wantonly in the city, and in the endless pain... Maybe death is no longer your enemy, but eternity is. Death is a beacon, no matter which way you sail, you will eventually turn toward it. Everything will pass away, only death will live forever. (The author has not read the original work, and only made a second creation based on some settings and known parts of the original work)
