Guo Pu was displeased, "How can such a good thing be temporarily shelved?" If it must be shelved, why show it to him? Having shown it, how could he not receive a finished product?
Fu Tinghan quickly explained, "Because at this time it's truly not usable. I didn't intend to give it to you; it's because you didn't understand how radio waves are transmitted from a radio station that I materialized it for you to see..."
Guo Pu was aware of Fu Tinghan's personality and knew it wouldn't help to argue with him, so he took a more circuited approach, "Do you know how expensive lamp oil is? Once night falls, the only places with lights in the Capital City are wealthy households. The homes of ordinary citizens don't even have a single lamp. If this tungsten filament lamp could be produced, it would benefit countless people."
Fu Tinghan came from the modern era; how could he not know?
The main issue is that they don't have electricity!
