The receiving of messages was easy, but transmission was a bit more complicated.
"The domain will need to be able to transmit signals, which means that I will need to have guidelines on how to produce the needed signals," Rui murmured. "What is the best way to produce the kind of electromagnetic activity that elven brains are evolved to produce?"
There were numerous principles of physics that Rui could rely on to produce electromagnetic activity, but the simplest one was to alter the electromagnetic activity of his own brain to match that of the kind of signals that elves produced.
According to the elven research data that he had obtained, elves had much greater brain activity when communicating with nature.
It was sort of like how Martial Apprentices had much greater brain activity while fighting because the cognitive endowments that they had received were only available in combat. The elves appeared to have something similar in regards to their brain activity.
