Otherwise, if the soul spirit's strength is insufficient, not only is failure likely, but there's also a risk of injuring oneself during the soul-splitting process. In severe cases, it might even lead to direct demise.
Secondly,
during the initial soul-splitting, one requires a divine sense that is stronger than one's own soul spirit as support.
The strength of this divine sense must be at least close to twice that of the soul spirit's strength. Fulfilling this condition also presents some difficulty.
A cultivator's divine sense is generally comparable to the strength of their soul spirit. The stronger the soul spirit, the stronger the divine sense naturally becomes.
Wanting the divine sense to surpass the soul spirit requires external assistance.
It could be through the use of certain elixir medicines or spirit grass to stimulate, or some special magical treasures, or even certain cultivation techniques that can enhance one's divine sense in a short time.
