At first Saleen thought he could continuously use trial and error to understand the theory behind the magic patterns, however; he had not expected the blue current to use up this much energy.
It seemed like only Alchemy City could withstand such expenses. Saleen's finances alone were limited and he could not afford to use such methods to uncover the secrets of the electric current.
In less than a second, he had used up more than two-thousand gold coins. Such methods of spending had to be the fastest in history, even quicker than dumping gold coins into water.
The standard weight of a gold coin in the empire was twelve grams, two-thousand gold coins were heavier than twenty kilograms. Saleen still did not feel satisfied after spending over twenty kilograms of gold coins.
