Astrophysicist Dr. Vulcan's subversive theory that the universe is composed of macroscopic life forms has been ridiculed by mainstream academic circles. When the Andromeda Seven Galaxy was dissolved by the cosmic "antibody", the United Human Government was forced to use Vulcan to take over the "Spark" program. Vulcan and genetic engineer Lena Costa boarded the "Spark" spacecraft to escape, and discovered that human DNA contained 0.0003% Of junk sequences that were homologous to life forms in the universe. After being captured by the host, Vulcan sacrificed himself to transform into a biobeacon, using his life to imprint the evidence of the same origin on the universe's immune system. Before the energy in the embryo cabin ran out, Lena received a 0.0004% Homologous signal - a "double helix beacon" established by another civilization. She eventually encoded human genetic characteristics and communication algorithms and sent them, declaring the civilization's stance of seeking "symbiosis".
