Zheng Qing was currently using the law book provided for free by the school to scholarship students. It had a reddish-brown cover, soft mulberry paper, and measured one foot two inches six parts long, eight inches nine parts wide, with one hundred eighty pages thick.
If the spell formulas were concise and the handwriting neat, it could record eight to nine spells; if the handwriting was slightly messy, it could only accommodate five to six spells.
The law book that Zheng Qing had originally customized at the Lower Yuan Bookstores could easily hold more than ten spells. But now that law book had turned into a 'trigger' for forbidden curses, rendering it unusable.
Xin Fat Man also noticed the look of the law book that Zheng Qing was patting and raised his eyebrow: "Can you still use your original book?"
