Condensing a Soul Core required two conditions: the quality of one's soul power, and sufficient spiritual power.
The full name of a Soul Core was Soul Power Core. It compressed soul power from liquid into solid form and sank into a soul master's dantian. That was a Soul Core.
In theory, as long as a soul master focused on the quality of their own soul power, once they broke through to the Soul Saint stage, the quality of their soul power would be sufficient to condense a Soul Core.
The reason only those who reached the level of Titled Douluo could condense a Soul Core was because condensing a Soul Core also required enough spiritual power to operate it.
Thus, ten thousand years later, when soul masters had the awareness and ability to cultivate spiritual power, most soul masters could begin condensing Soul Cores at the Soul Saint stage.
To condense a second Soul Core, one needed a greater total amount of soul power and higher-quality soul power. Generally, it could only be condensed when breaking through to Limit Douluo, and this was also the method by which soul masters of this era broke through to Limit Douluo.
However, in truth, just like the First Soul Core, as long as one met the standard for condensing the Second Soul Core, one could condense the Second Soul Core in advance.
But the First Soul Core and Second Soul Core could not be located in the same dantian. Otherwise, that was just asking to die.
A dantian was not a sphincter. It could not be stuffed with that many strange things.
Moreover, during the process of condensing the Second Soul Core, one also had to pay attention to how the Second Soul Core and First Soul Core coexisted.
