The fundamental enigma of these 36 runes is something Fang Yun doesn't have the time or qualifications to research at the moment.
But what these 36 runes can do is utilize one's own essence blood to spread throughout the entire Blood Seal Magic Artifact.
Then, one can open up the channel between the body and the Magic Artifact, allowing for complete infusion of one's Mana into the artifact.
Similarly, the Blood Seal Magic Artifact also has the ability to change its size and shape.
Fang Yun doesn't know if other Blood Sea Martial Artists have this ability.
However, during his use of the Five Elements Plants, he discovered that these two functions—necessary for the vine—can be easily accomplished with the Five Elements Plants.
In this way, as long as he figures out how to turn this vine into his Blood Seal Magic Artifact, he can completely solve this problem.
And the most fundamental restriction in refining a Blood Seal Magic Artifact is the consumption of essence blood.
