Gazing at the Golden Core within his Dantian, Lin Yi fully understood everything. The Golden Core's existence was not to coexist and perform its duty with the Nascent Soul, but to nurture another Nascent Soul.
This is the creation of the Nascent Soul Realm, possessing two Nascent Souls, one yin and one yang, the upper one yang, the lower one yin.
In fact, the divine skill of reversing the Golden Core in the Tenth Level was created to lay the groundwork for the Twin Primordial Spirits.
A regular Golden Core rotation possesses ordinary elements, which are pure yang, representing yang, while the Jin Dan reversal showcases dark elements like rot and decay, as well as poison within the Wood Element, representing yin.
When he nurtured his Nascent Soul, he tapped into the pure yang qi from the Golden Core's ordinary rotation.
Now, however, if he wants to nurture the next Nascent Soul, he must reverse the Golden Core and then begin the nurturing process.
