None of these books were normal at all.
They gave off the same feeling that was only slightly inferior to the one that Ye Qing Huan gave off. However, that wasn't surprising since the cultivation technique that Ye Qing Huan cultivated was one that had sustained the Heavenly Demon Sect for years.
If the aura of these books was just slightly below that, then they would be considered treasures in any of the Five Great Sects.
No, since the four righteous sects were considered lower than the Heavenly Demon Sect, it could even be said that these were on the same level as the core cultivation techniques as the four righteous sects.
With how many books there were here, it was an absolutely shocking sight.
Though it wasn't as if cultivation techniques alone meant that one would be able to become a powerful cultivator.
It all depended on one's aptitude and how much they would be able to gain from the cultivation technique.
