Flying Dragon: The Secret Scroll, also known as Hiryuu no Ken: Ougi no Sho (飛龍の拳 奥義の書, Fist of the Flying Dragon: The Book of Mystery) is an action platformer developed by Culture Brain for the NES and the second game in the Hiryuu no Ken series, the first one being the arcade game Shanghai Kid. The levels consist of platforming beat 'em ups, where powerups can be collected in addition to the plot coupons of the game, along with more traditional fighting game levels.

The plot involves a Chinese martial artist named Ryuhi, who goes on a quest to avenge his master after he was killed and all but one of the titular secret scrolls were stolen. He later learns that a gang called the Tusk Soldiers were responsible and have entered the World Tournament of Contact Sports. Ryuhi signs up for the tournament so he can retrieve the scrolls and finally avenge his master with the power of Hiryuu no Ken.

In this run, Ighalli plays the Japanese version of the game for its quicker training sections and completes a single run of the game in record time, winning the world tournament and getting to the first ending of the game.
