Liu Zhiguang really had a knack for martial arts. Although he wasn't much interested in reading books, he took great pleasure in studying military treatises. Moreover, anything he read once, he could integrate and apply effortlessly. There was an instance when Liu Siliang was working the fields with his sons, and during a break, Liu Zhiguang arranged cornstalks into a formation. Were it not for this slip that exposed him, perhaps Liu Zhiguang would never have discovered his older brother's secret.
However, the military treatises that Liu Zhiguang read were mostly purchased from street stalls, some were damaged and incomplete, while others had faded writings that were hard to discern. There wasn't much choice; these old books were much cheaper than the new ones. The silver that Liu Zhiguang saved by skimping on food each month wasn't enough to buy even one new book, but it could get him several old ones.
