In the end of the novel ROCH, there is this passage:
To me, the phrase "complement each other" suggest that these two manual will help one another thus further suggest they should be learn together. But I thought these two manuals had highly opposing theories.. so how could these two manuals be consider complimentary?Master Damo had written another book, which was the ‘Nine Yang Manual’. This book had the same value as the ‘Nine Yin Manual’; as a matter of fact, these two books complement each other.
