### Summary
The chapter shifts from ceremonial tension to comedic revelation as Erden shows the 12-year-old Letitia an indecipherable book written by a legendary "Great Sage," believed to hold the key to fighting devils. The central plot point, which readers found hilarious, revolves around Letitia's internal monologue where she sarcastically muses that she could only read the cryptic text if it were written in Korean, only to discover it is, in fact, written in Hangul. This "convenient" twist was widely anticipated and celebrated in the comments, sparking an immediate and dominant fan theory that the sage was also an "isekai'd" individual from modern Korea. Readers connected this possibility to previous anachronisms like butane gas, solidifying the belief in a predecessor. Alongside this major reveal, commenters noted a change in the 15-year-old Erden, who displayed uncharacteristically boyish excitement and blushing around his new wife, contrasting with his fearsome reputation. Other details that drew commentary included the intensity of a blood ritual involving sliced fingers to open the book, a brief glimpse of Erden's hand, and Letitia's own comedic moments, such as her surprisingly effective punch and her preoccupation with getting a meal before facing potential death. The discovery firmly establishes Letitia's unique importance to Halstead and introduces the compelling possibility of other reincarnated individuals having existed in this world before her.
