A small lamp with the intensity of a 100W LED bulb in my previous world can consume a white crystal in 3 days if that bulb is always on, and the amount of mana it takes to launch a small fireball, my cheapest magic ability, can ignite that same bulb for 10 days.
But for ordinary people who have no mana, crystal coins are their energy source to power alchemical artifacts!
So magic crystal coins have become very popular in the capital and are slowly spreading throughout the human population and other realms.
Thanks to the library I was able to learn about the Alchemist who managed to condense mana into crystals by making a leap to the use of alchemical artifacts comes from the Noble Family Petros, a noble family at the level of the Athenahotep and Morwenna family.
Although the crystallization of mana at the beginning was very complicated and the use of high energy, over time it has been perfected by creating the first crystal coins twenty years ago.
