Qin Gu traveled across the Qin Dynasty and became the "idiotic" seventeenth prince living among the people. Facing the First Emperor who visited under a pseudonym, he bluntly stated that his elixir was poisoned and asserted that the Qin Dynasty would be in chaos. Ying Zheng was frightened and returned to the palace. He followed the instructions and rescued himself, and even sent elite guards to protect him secretly. He didn't know that this "silly son" had a shocking plan to turn the world around.
