The martial arts Taiji Manual was divided into five levels. The first level was the Yin-Yang Stance, which corresponded to the Bright Force stage. The second level corresponded to the Dark Force stage, the third level corresponded to the Hua-Jin stage, the fourth level corresponded to the Dan Force stage, and the fifth level corresponded to the Supreme Force stage. There were no higher levels, and then the Superclass ruled the overall situation.
Due to the catastrophe decades ago, only the Superclass and the first level of Yin-Yang Stance were left in Taiji Fist. The remaining levels, from the second to the fifth level, were lost. At most, one could only cultivate to the peak of Bright Jin and could not cultivate to a higher level. That was why it was getting worse day by day.
However, this might be a huge disaster for Taiji Hall, but for Zhu Wuwan, it was just something that could be easily resolved.
