The mage explains that bloodlines are divided into three levels: mortal, mystical, and king. If they are king levels, then why didn't the mage know about them? . . He also explains that the secret rank of a person's bloodline is only one level higher than the actual rank of the person. So, if you're a prince and you have a hidden rank of nine, that means you've got a lot of potential, but you don't have enough potential to be a king. So you need to learn how to use your bloodlines to improve your abilities. The only way to do this is to practice using techniques that complement your bloodline. The best skill scrolls at home are at the low stage of mystic level, but the best techniques are at heaven's level, which are scrolls that can even be legendary empires. The scrolls that tian-lin chooses are the scriptures of millions of shadows. This is the strongest among the nether elements, and at the peak of cultivation, one can replicate himself into millions. This will be extremely compatible with one's physical attributes.
