Jia Ping'an time-traveled to Great Qin, happened to encounter a newly appointed county official who died by falling off a cliff, and thus assumed his identity. To protect his identity, he worked hard to govern the locality, developing the impoverished county into a utopia. Thinking he had hidden it very well and would be promoted and receive noble titles in the future, he never expected that the original owner's father was actually coming back! As it happened, on this day the First Emperor returned from his eastern inspection. He made an unannounced visit and pushed open the gates of the Jia residence. Looking at the mountains of potatoes piled up in the residence, the First Emperor's eyes lit up. Then looking at the honest Jia Ping'an, he decided to conceal his identity and impersonate his father.
