As a spirit in a transitional state, Zhou Hu is awaiting awakening, which indicates that his situation is not good at all. It's like he's destined to keep reincarnating until his last life, ready to grab the lifeline given by fate.
As an auspicious beast, that's pretty unlucky.
In Qin Huai's spirit guide, there are many auspicious beasts, and they generally have better luck. The Wen Yao Fish is an exception, being extremely stubborn, but even so, he had the fortune of meeting a legendary good boss like Han Guishan who helped him succeed in Crossing Tribulation. That shows the luck of auspicious beasts.
And as for Dang Kang, he muddled through a failed Crossing Tribulation, then muddled through a successful one, truly a master of muddling through.
Compared to these two, the Nine-tailed Fox seems like it's been cursed by heaven.
