Hesham ibn Hakam's So Called First Meeting with Imam Jafar as Sadiq (as)

I read Hesham ibn Hakam's biography by Mamghani, and already I see that the book is filled with lies just to boost of the status of the 12er shia chief Hesham ibn Hakam.
The 12er shia tell us Hesham ibn Hakam met Imam Sadeq, and in his first meeting the dozener's chief got an opportunity to learn from the imam. Lets see how the 12er shia narrate this event.

Mamghani writes:
"Hesham asked the Imam [a] about five hundred problems and questions in his first meeting and received correct answers for all of them. As a result he was so much enchanted by the divine greatness of the Imam [a] that as long as he was alive, he was the greatest defender of the Wilayah of the Ahlul Bayt (the guardianship of the Prophet's household [a])."
(Tanghih al-Maghal by Mamghani; "Usul Kafi" vol.2. Pg. 13)


500 questions in one meeting ? Even if we consider one question to be answered per minute it would take over 8 hours to get through 500 questions. Also, its seems like Hisham had some superhuman strength to absorb all this information in one meeting.  Aside from that there are no works which tell us about any of these 500 questions. In fact, even 1 question is not narrated for this meeting.
