It looked like the space merchants really weren’t planning anything sinister this time, or at least it seemed to be so from Yao Yuan's, Ren Tao's, and Xiao Niao’s observations.
The space merchants took fifteen days to transfer a large amount of tech information and details about the cosmos to humanity. After that, the big-brained aliens planned to escape using a small spaceship, abandoning their mother ship and other races. This plan was rejected by Yao Yuan because he was afraid the big-brained aliens were secretly planning a self-destructive sequence on the mother ship, which would blow up the humans on it. Who would the seek compensation from them then?
