After purchasing the Astral Swirl, Lin Feng also went to search for the remaining six levels of Nonuple Body Tempering. There was indeed Nonuple Body Tempering in the school's shop, but the number of purchases was very small.
Lin Feng thought carefully and roughly understood some of the reasons.
The last six levels of Nonuple Body Tempering required 100 merit value per level. This was simply daylight robbery. At this price, almost no one was willing to buy it. It was just too expensive.
The reason was very simple. The Nonuple Body Tempering was not a martial art that used Astral Power, but a martial art that mobilized pure physical strength. Why would any inhuman expert who had broken the genetic lock care about physical strength?
All inhuman experts who had broken the genetic lock had shifted their focus to studying Astral Power. For example, a casual strike from a first level Metamorphic Realm martial artist could only exert about 100 tons of strength.
