A Single Thought Spanned More Than Fifty Years

Becoming an immortal or becoming a demon: it all depends on a single thought.

How long is a single thought? After poring through ancient books and researching the matter, a young cultivator who had little interest in cultivating immortality discovered that a single thought lasts more than fifty years.

For an ordinary person, more than fifty years is half a lifetime. But for demons and cultivators, fifty years is a very short time.

So, as it turns out, a single thought can last quite a while.
