Travel Through Another World and Catch up with the Changes in Martial Arts

Late at night, Zhang Wen was sitting alone in his room, looking at the table with bright eyes: The one on the left is a red lacquered square book box, with the inscription on the top "New Edition Seventeen of the Imperial Encyclopedia of Da Chen's Martial Arts", Da Chen's Official Martial Arts Encyclopedia! The one on the right is a black lacquered 'piano case', with the words "Secret box type long-handled fire·Ping'an Pavilion private order" printed in ink on the lower right corner. This is clearly a rifle! … A sword in one hand and a weapon in the other. Zhang Wen's journey into the world of martial arts has begun.
