The "Essence of Swordsmanship," which Ye Weiming had previously received as a task reward, did not differ much from the secret books of martial arts insights he had obtained from corpse examination, both in name and in description.
In his opinion, after going through this book, it would probably boost his proficiency in swordsmanship by 450,000 points at most.
However, that was more than enough!
With this 450,000 points of swordsmanship proficiency and the massive amount of Cultivation Points he had accumulated from practicing his swordsmanship, it was enough to significantly enhance his strength, whether by upgrading the intermediate "Yue Girl Sword Art" to the perfect 10th Level or raising the "Heaven-shocking Nine Swords" Technique to the 6th Level.
However, with his current accumulation, he could only choose between these two enticing options; he couldn't upgrade both sword arts simultaneously, which was slightly disappointing.
