the first story was secrets which took place in modern day time
VChan04: this is the sequel so it's about 20 years in the future
VChan04: the only reason they don't have some things that we do is because they are on a different planet
VChan04: and the only technology they care for is anything dealing with battle or murder
VChan04: and the basics of course
VChan04: and their scientists have a few things of their own so they might have different names for similar products
VChan04: also, they have minimum communication with earth, almost as if earth in general doesn't know about them, but the head of the planet do (think conspiracy theories about aliens)
VChan04: and in trade for being quiet and trading a few things, they don't get blown up or destroyed by the Saiyans

This was an IM I had with someone about if Vegetasai had halogen lights.

Overall, Vegetasai has a few points that are primitive and a few that are modern day and a few more that are futuristic. This is all because of the different planets they purge and races they come across. Hope this explains a few things.
