The benefit of Spiritual Talent lies in that you can take it slowly, whereas the downside is that you might die before you've fully cultivated it. In short, if you wish to touch the realm of Immortality in this way, it's practically impossible.
To be precise, neither cultivating spirit nor Inner Qi can change the fact that there's never enough time, not enough time for you to deepen it to the cellular level, which is a problem for all life, whether cultivated or not, time is insufficient.
Xuu Chu didn't have much to feel about these because what Huang Zhong said didn't completely align with his cultivation experiences. For Huang Zhong, the spirit that integrates into the body surpasses Qi and the body, creating a sense that as long as my mind remains, I shall exist.
However, for Xuu Chu, the presence of spirit only allowed him to better control his strength and didn't have the magical implications Huang Zhong described.
