"Feng Shui Masters who nurture immortals are feared and shunned by tycoons like Song Tianyi."
After all, everyone knows that "immortals" are highly malevolent. They may assist you initially, but once they've helped to a certain extent, they will turn on you and harm you.
Those who frequently employ Feng Shui Masters who nurture immortals inevitably face terrible fates.
Moreover, these immortals not only harm the families they frequently assist; often, as the Feng Shui Masters age, the immortals may even harm the very Feng Shui Masters who once nurtured them.
Such immortals, inherently rebellious, do not bring good fortune.
Using them once or twice might be okay, but frequently? Heh, you'll surely be harmed!
As a result, influential figures absolutely keep their distance from Feng Shui Masters who nurture immortals.
