The so-called Primordial Spirits of Three Separations referred to three separated incarnations which had their own primordial spirit.
This skill divided all the knowledge one gathered in his whole life into four categories. One could then assign each of them to his three incarnations: primordial spirits as well as his own body respectively. Every incarnation or the primordial spirit it carried, would be used to develop a particular technique and focus on honing its skill. In this way, one man could possess a combat capability equivalent to the combined power of four men. Meanwhile, it would also improve one's martial phase. Hence, it was a very powerful Divine Sense.
