Money, tools, and martial arts

Some common knowledge:

-=Money=-

10x silver coin == 1 gold coin

100x gold coin == 1 low-grade spirit stone

1000x low-grade spirit stone == 1 mid-grade spirit stone

1000x mid-grade spirit stone == 1 high-grade spirit stone

Note: the coinage below the silver coin is also known as peasant money so this young master doesn't know about them.

Fun fact: cultivators can create spirit stones using their Qi but the process is not fast and a minuscule number of cultivators would take the time to do so, so most of these spirit stones are the ones that were formed naturally.

-=Tools=-

Magic Tool, Spirit Tool, Treasure Tool, Spirit Treasure, True Spirit Treasures, and Fairy Artifacts (each grade has rank 1 to 9 with three sub ranks; low, mid, and peak).

Fun fact: there are only seven known Fairy Artifacts in the world and they are in possession of the seven holy lands of the divine central continent.

-=Martial arts=-

Lower, Middle, Upper, Earth, and Heaven (each of them has ranks of 1 to 9).

Fun fact: having a good martial art usually would paint a target on your back because others would also want to have it…
