As a system made with the objectives to made people reach really high cultivation level naturally the Cultivation Scipture were the best of the best. According to the explanation of the system the grade of all Scipture were classified by Stars like the Cultivation Talent. But the System only has 9 and 10 star Cultivation Scripture and the lowest Martial Scripture is 7 stars from what I learned. And so that was the five best Cultivation Scripture I got by the system for my affinities :

  ...... I won't say that I wasn't expecting it but it still made me sad that even with a supreme cultivation system I don't have much choice on my Cultivation Scripture, I mean I am a lawful modern person. I won't go killing people for cultivating from today onward so I don't have a lot of choice. Even so I think I would have chosen this one if I had the choice because it was particularly mysterious without any information apart what is needed for progressing in it. On top of that a Blade Scripture was included in it and it needed the highest affinity. All that made it the most mysterious of all the Scripture that I could choose. And so I choose it. So after choosing it I obtained the Manual in the Scripture part system. Naturally I was impatient to read the detailed information on this mysterious Scripture.

  I was young and I didn't understand that day that there was no more than 20 Arts in the multiverse that can boast of making someone understand the Space Laws only by studying it.
