This ancient book is the condensation of countless sword techniques in Chu Fengmian's mind.
Recorded within this ancient book, each page contains exquisite swordsmanship from the Ancient Times.
If this ancient book were taken out, it would definitely be enough to make countless strong individuals in the Nine Domains compete for it, even the seven major sects would strive to obtain this treasure.
But now, gradually in Chu Fengmian's mind, this ancient book is becoming thinner and thinner, leaving only the essence of the countless sword techniques recorded, while all the unnecessary impurities have been directly refined by Chu Fengmian.
Under the sweep of Chu Fengmian's divine sense, this swordsmanship was continuously condensed, gradually transforming into a single sword technique.
This single swordsmanship, reborn from the ancient book, is much stronger than any sword technique recorded in the ancient book before.
