Description:
In the modern world, qi is money.
The days of traveling martial
artists and mountaintop masters are over. Power is controlled by
corporations, modernized martial arts sects, and governments. Those at
the bottom of society struggle as second class citizens in a world in
which power is a commodity.
Rick has attempted to separate
himself from the world of cutthroat killers, but is drawn in by a chance
to participate in a contest at the highest levels. The resulting trials
will take him across the world against many different opponents, but he
knows that his sponsors ultimately just want to use him for their own
profit. In the end, he'll need to decide what it is that he really
wants...
