After forging solely in the created embryonic heavenly furnace for a few days, Mo Wen's cultivation of Yin Yang Qi was now on a par with practitioners at the pinnacle of the Primordial Soul Realm. This was all done without the shackles of the realm, exceeding the regulated breakthrough. The cultivation of a practitioner was like a well. Those who were at a higher realm had deeper wells, and breaking through to a realm was the process by which the well deepened.
But the size of the well opening varied from person to person as well, and this hinged on their talent and growth process. For a regular person, the opening of their well was about as big as a millstone, whereas Mo Wen's was as big as a pond. Though both were equally deep, the amount of water that could be stored was vastly different for each of them.
