Bai Yishan was very efficient and sent Han Sen all the information of Heresy Mantra the second day.
Since Heresy Mantra had not been adapted into a hyper geno art, it was written in an ancient language and was very hard to read.
It was an age when everyone practiced martial arts, most people knew some terms in the ancient language, and so did Han Sen. However, Heresy Mantra was still beyond his understanding.
Luckily, the professors that studied Heresy Mantra before had left a lot of footnotes. And the previous volunteers had provided notes and data as well, which had helped Han Sen greatly.
Bai Yishan also gave Han Sen some tips, which would help Han Sen avoid making mistakes when practicing Heresy Mantra. It seemed that Bai Yishan had also done profound research on this ancient martial art.
