The burly black man followed Richard to the upper level of the bookstore with some trepidation, but to his relief, Richard didn't reveal his "offensive behavior" to the shop owner Hadi and left the bookstore directly.
After leaving the bookstore, Richard quickly exited the Underground Market and returned to the laboratory.

Laboratory, main lab.
Richard laid out the eight books he had purchased in a row on the table, his eyes shining with certainty about his previous conjecture.
Of the eight books, three were copies of "Path to Nobility" that he already owned, with codes from the Black Spirit Empire emblem being 1, 2, and 25 respectively. Three were copies of "My Autobiography - Moratos" that he already owned, with codes of 18, 27, and 36 respectively. One was a copy of "Blood and Fire" that he already owned, with the code being 20. The last one was a magic book called "Soul Wail," with the code being 5.
