Please Tell Me

Emma trimmed down the runes needed for the artifact and even wrote down ways to replace them. Instead of runes, the artifact would use scanners or a programming language to retrieve the information. The visualization would still need runes to be achieved. 

"The mana cost is a tenth of what it used to be," Emma said with a smile. "If we can supply both runes and electronics using the same battery, it could be sold at the same time." 

Everyone was stunned as she managed to optimize their work in just a few minutes. Arthur smiled because this was the type of innovation that he wanted. People were too reliant on mana and runes, so it was reassuring to see them recognize the advantage of electronics. 

"Mana is a precious resource that will never be too abundant. However, there is always a possibility that it could disappear. As long as we utilize the laws of physics like Emma did, we can become independent as human beings," Arthur addressed the crowd.
