The Swords of Slaying Immortals appear to be in the hands of the Jiejiao Sect's four Golden Immortals on the surface, but in reality, each sword was restricted by the four Saints that broke the array back then, rendering them incapable of resonating with the Jiejiao Sect's group of immortals.
It could be said that without the permission of the Saints, unless an Upper Qing Saint personally intervenes, no one could retrieve the Swords of Slaying Immortals.
Otherwise, the power of the Chan Teaching's four Golden Immortals is no match for Saintess Wudang; if they had been able to act, she would have already snatched the Swords of Slaying Immortals back long ago.
"Ideas are conceived by people, and with the wisdom of the young friend, retrieving the Swords of Slaying Immortals shouldn't be difficult for you."
