But is this really the case?
Just look at Lu Yuan to know the answer.
He cultivated the Fortune Dao, a Burning Life Method that, although it consumes the cultivator's lifespan extremely quickly, with life passing more than ten times faster than a normal cultivator.
However, as a return for the price paid in lifespan, Lu Yuan's cultivation speed was also seven to eight times, or even eight to nine times faster than that of a normal cultivator.
Even though the return he gained still wasn't as much as the life he spent.
Yet, looking purely at the rate of his rapid progress, his cultivation speed was indeed considerable.
Even so, with such a swift speed, it took Lu Yuan from his seventh year in the Hongdao to the fifth year in Shenwu before he succeeded in Gathering One Qi.
In between, he spent eight years, officially entering the Immortal Sect.
If calculated according to an eightfold increase in cultivation speed, it equates to sixty-four years for an ordinary person.
