"Don't you have a rough estimation?" Jiang Pengji had some guesses in her mind, but she did not have any precise evidence. There was only a word or two about the Hanshi powder in the many books she had read before.
According to the records of unofficial history, a roaming alchemist in the former dynasty presented a magical prescription that could prolong one's life and strengthen one's body to the emperor of Xia. The prescription could provide men with ample Yangyuan and energy for sexual intercourses. The prescription was the Hanshi powder. It was also said to cure typhoid fever.
Before the five kingdoms were separated, the Hanshi powder was a secret formula in the palace and it was not disclosed to the public; only the emperor was able to enjoy it. After the five kingdoms separated, the Hanshi powder, which was once a sacred thing, disappeared without a trace. When it reappeared, it had become a popular activity of the upper class.
