Even a mana gemstone the size of a fingernail contains more magic power than tens of tons of mana metal, with a value reaching millions of gold coins. That's why the mana gemstone embedded at the top of the Holy Sword's hilt is only the size of a glass bead.
Therefore, the mana gemstone is one of the highest-grade magical materials in the Source World.
The mana gemstone that Reiger obtained earlier was about the size of a baby's fist.
In the teleportation magic formation at the dwarf's dwelling, however, there is a mana gemstone the size of an adult's fist embedded.
Such a large mana gemstone ultimately can only provide three uses for the teleportation magic formation.
After three uses, this mana gemstone is rendered useless.
This demonstrates how difficult it is to popularize teleportation magic formations in the Source World.
Unless it's a critical moment, even if a teleportation magic formation is set up, it is rarely used.
