The experiments that Jeff dabbled in weren't normal one's that researchers would usually do. Jeff only realised how powerful his system was when he started to study it in-depth. And his starting point was with the very first reward he'd obtained from completing his very first mission, Apocalypse Shop.
This shop, although small, had its own pecs. It provided unique items and goods that were then sold to the customers like Cleansing Water which rid one's body of impurities by simply drinking it. It also had other goods like the Calming Mind Ice Cream, Skincare Dew, Healing Mud and other products which the consumers were extremely interested in.
Jeff also realised that when inside the shop, everyone looked at him with reverence and awe as though he was a great figure, also that the shop was built in such a way that no outside interferences like Curses, Divinations, Tracking Spells and all kinds of phenomena worked inside the shop. Everyone inside was safe.
