One Hundred Thousand Years of Return Voyage

It is assumed that human civilization is the intervention of civilization from Sirius. The Sirian civilization has developed a technology that converts entities and consciousness into a stream of energy, which can travel through the stars on a super laser. Spread civilization in alien galaxies suitable for development, or communicate with alien galactic civilizations. These explorers, transformed into energy blobs, rely on the light of stars to survive and move. After arriving on a planet with living things, they select one of the best creatures and perform interference and fusion to make it suddenly intelligent, or interfere with an already intelligent creature to make its behavior develop as expected. Each time they interfere with the fusion, they will lose a team member.
