The Nangong Emperor was skeptical, and for good reason, as he had sent a eunuch to supervise the grain transport, who witnessed the entire process.
According to the eunuch's report, the Emperor concluded that they had been putting on a show! It was ridiculously fake!
At this time, grain was generally transported using mule carts or horse carriages. A mule cart can carry about two hundred catties of grain, while a horse carriage can carry even less.
The two granaries, containing hundreds of thousands of catties of grain, would require a vast number of mule carts to transport them all in one night. How could such a huge caravan move without making a noise?
Moreover, Nangong Country had not invented cement yet. The official road was not a cement road, but an ancient loess road. It had rained heavily two days ago, and the surface of the official road was still not dry, with some low-lying areas a bit muddy!
