Sage Monarch Three Weeks did not know that Sage Monarch Seventh Cultivator of True Virtue had once possessed the Nine Virtues Phoenix Saber.
No matter what, the Nine Virtues Phoenix Saber was a Wielder of the Will's primordial treasure. With him having once been the master of such a primordial treasure, Sage Monarch Seventh Cultivator of True Virtue's vision was, of course, far beyond that of an ordinary Profound Sage as some views had been influenced by the primordial treasure. Let alone Profound Sages, there would even be some Immortals who wouldn't be able to provide him with answers.
The title, [The Most Reliable Senior of the Nine Provinces Number One Group], that he had was not given to him in vain.
Sage Monarch Seventh Cultivator of True Virtue had all sorts of knowledge related to cultivation, whether it was about forging magical treasures, refining medicinal pills, formations, or talisman-making.
