The Nine-Ring Demon Domain might contain a tenth ring!
But that was only a legend, never confirmed. No one even knew where the legend had come from; it was all shrouded in fog.
After all, reaching the Immortal Realm was not something one could achieve simply by wishing for it.
Even with a suitable anchoring object and one's cultivation technique perfected, one still had to wait for a particular moment—and seize it—to have any chance of breaking through.
Under normal circumstances, one had to prepare far in advance: conceal one's traces, stockpile vast amounts of resources, then enter seclusion and completely empty one's mind, quietly waiting to seize that opportunity. Even then, it took a long time to enter that state.
Breaking through realms was already troublesome enough. Let alone attempting it in a place like the Nine-Ring Demon Domain, with enemies watching from every side.
That was not a breakthrough. That was courting death.
The Immortal Realm could not be reached in one bound. It required a great deal of time—several days, even dozens of days. During that process, forget fighting; it was difficult even to move. Should anyone make a move against them, they would be severely wounded at best and die on the spot at worst.
One had to know that to interrupt such a breakthrough, there was not even any need to truly injure the person breaking through. The slightest disturbance was enough.
Who would dare break through inside the Nine-Ring Demon Domain under such circumstances?
Thus, the matter itself had become a legend.
After hearing Li Wufa's explanation, Li Su nodded and said nothing more. Since Di Gongrui had specifically reminded him of it, he would naturally understand once he found her.
As for breaking through, well, it truly was not difficult for Li Su.
