Depending on these conditions, the use of "Hundred Miles Escape" can be considered extensive or limited.
Take He Zhengsong himself for example, now over three hundred years old, he can barely execute a few long-distance escapes spanning a hundred miles.
Based on such a situation, it is speculated that if He Zhengsong were to surpass five hundred years of age, even if he forcefully executed this technique successfully, he likely wouldn't be able to maintain his Mid Stage Golden Core realm.
Even the possibility that he could die immediately after successfully teleporting is not out of the question.
Under such circumstances, many cultivators, even if they obtained this technique, might not be able to cultivate it successfully.
Even with successful cultivation, there would be few opportunities to use this technique to save one's life.
Overall, this secret technique of escape still holds considerable value.
