Why is there no Oracle Bone Inscriptions on the spell?

The spell was invented from the Qin Dynasty, and was actually interpreted by Sanskrit people. There are three kinds of Fu Tou, Shen Fu and Fu Dan.

Fu Tou: About three o'clock represents three fires.

Tattoos: It's hard to explain in Sanskrit.

Fu Dan: It was painted after the end. There are many kinds.

I wrote them all personally, because I have practiced boating.
