During the cultivation of Martial Arts, a cultivator needed to experience four Postcelestial stages, including Martial Student, Martial Disciple, Martial Artist, and Martial Soldier. In the four stages, the cultivator could achieve the best condition of his body through refining his human body, blood, bones, organs, and so on. These would form the foundation of his Martial Arts cultivation later on. Musen referred to these as the Foundation Establishment of Martial Arts.
In fact, the primordial stage was the real beginning of the Martial Arts cultivation. When a martial cultivator reached the primordial stage, he would be able to choose his own Martial Arts. Though Martial Arts were just one of the 3,000 Ways of Great Way, it contained thousands of changes. This meant everyone's comprehension of the Martial Arts would be unique.
