5x5 Multi-Blind gone horribly wrong in Line Walker 2 movie

[abunickabhi]

Movie: Line Walker 2 Invisible Spy (Cantonese movie) Director: Jazz Boon (hats off for trying out this random idea of 5MBLD in this movie.) ~2560 letter pairs memorised by each kid, if they are using stuff to save algs, ~2700 letter pairs if they are doing it via the beginners method, the memo should take about 5-6 hours if they are world class, maybe more, if they are reviewing a lot. No idea why the director Jazz Boon chose to delve into 5MBLD.
