i believe that its a good novel, hovewer i still dont like the time frame of development on it. i cant agree to aknowledge that 100K or 300K of people can build a modern kind of city in just 3-6 months. just the idea to rebuild and get the resources to build a city for 100-300 k people in 6 months frame time alone is crazy. dont get me wrong i do like the novel, but this is the third o forth chinese novel that get that kind of idea as if its normal fact to be capable of be done. well now its time to wait a see what the mc would do with his system

first the gold is a not magnetic metal, so using a magnet seek ifit fake money it is bad idea. also coin making in the meddle ages was a process doing by hand. all the coins were irregurar without a proper form. and a thougth about your vending machines, it will be easier just to provide credit vouchers that were to be used on those machine, and be selling it several places. but i believe that its too much tech about those when 95% of the people its not aware about how its working outside your city
