This story absolutely happened in the 34th year of Qin Shihuang, when Ying Zheng was 47 years old. The reason why you didn't read it in "Historical Records" is entirely due to Sima Qian's manipulation, because this story is very unfavorable for him to demonize Qin Shihuang and severely punish him for the torture and tyranny of the Qin Dynasty in his imagination. If after reading this story you not only sneer but also angrily accuse me of fabricating facts, then I can only cry in the corner and blame myself for not being born before Sima Qian. Because people generally believe that people who are closer to the historical era are always closer to the facts themselves. But in fact this is not reliable, at least compared to hundreds of years ago, we now have the terracotta warriors and horses as ironclad evidence.
