When Ying Zheng learns from me that the immortal pills he takes every day are actually poison, and then hears me say that the First Emperor won't live for more than a few years, he becomes so furious that he spits blood and curses me as an unfilial son. It all started when I traveled back to the Qin Dynasty and accidentally mistook the First Emperor, who was disguised as an ordinary man, for my father. From then on, Great Qin gained a bickering father-and-son duo. I criticize my dad's elixirs, berate his steward, and even teach him a thing or two about governing the country.
