The fundamental reason is not that the opportunity is hard to find, but rather because the breakthrough is extremely difficult, and if one fails, it can result in death or severe injuries, diminishing one's strength with no chance to advance to the Sword Saint, leaving many once famous geniuses forever regretful.
Because the breakthrough to Sword Saint is so difficult and dangerous, many Great Swordsmen who feel they have mediocre talent don't dare to try even if they find the opportunity, and even many wait until they are nearing the end of their lifespan, feeling life holds no more for them, and only then do they risk everything in one last effort.
And this Limitless Saint Transformation Pill not only greatly increases the success rate of advancing to Sword Saint, but most importantly, even in failure, it will inflict no harm.
