Demon Sutra mastery

It had been a while since he obtained the demon sutra and in the period, he was able to feel how extraordinary it was, but at this moment, it could be said that the change was massive. 

More importantly, it was not that he could not practice the technique to a higher level rather limited by realm. Even in the moment, it seemed that after he broke through to the essence Qi stage, it seemed that the practice at the mastery stage seemed to have opened up itself, as though it was sealed. 

The most important thing was that he could grasp a lot of information and it seemed to inform him of the fastest means to practice on this stage without worrying about foundation. In the same time, he was able to confirm that this demon sutra was indeed unique, but he was not in a rush yet. The means he had to fight the enemies might have worked before, but at this state he would not be able to exert much combat power in the same realm unless he improved on them.
