Every day, people were undergoing surgery to become extraordinary.
The technology became more and more mature, and later, surgery was no longer needed. Taking a pill and entering a device, operated by a physician, would achieve the same effect in ten minutes.
Then, one would enter an Array and sit cross-legged. The time it took for one to internally view their body's reaction chamber varied from two hours to a week, after which energy training could begin.
Those who had undergone similar surgeries found their energy training efficiency to be very high. Spending about two hours each day, one could wield a trace of extraordinary power in a month.
This was already quite exciting, as further practice could grant even stronger abilities.
The experience was too novel, resulting in most people wanting to give it a try.
