Generally speaking, the condition of having only a little bit of True Spirit left means that one still has the chance for a Past Life, which is slightly better than soul flight and spirit dispersal. Such a tiny bit of True Spirit cannot even support thought; it is merely Chaos, a complete ignorance. A single breeze could blow it away.
Otherwise, the Hanging Monastery wouldn't have given up on the rescue after hearing that Guan Yan had only a little bit of True Spirit left.
Guan Yan was the unique exception.
His bit of True Spirit survived in the interstices of the Forest Sea Source Realm for five hundred years without fading. He even figured out, with his unparalleled talent, a method of cultivation based on the True Spirit.
At that time, it had already shattered Jiang Wang's imagination. And now, Guan Yan was even communicating with him in the present world through the power of the Yuheng Star from the Forest Sea Source Realm!
