Barriers
For example, when conducting the trade, both sides would not want to be short-changed and be given techniques the net value of which were inferior to the techniques that they gave the other side.
That meant both sides needed to agree that the value of the techniques exchanged needed to be agreed to be equal by both sides.
This was where the complications arose.
For starters, what decided the value of a technique?
The Martial Union already defined the value of a technique objectively, using several parameters that it valued in a technique. Rui had already learned about it when he submitted the Pathfinder technique to the Martial Union.
The Martial Union judged the value of techniques based on four parameters; individuality, potency, difficulty, and dissemination viability.
