"Just to clarify," Han Yi hadn't chosen the Ancient Illusion Sky because it was the weakest within the Ninth Heavens; his decision was merely about convenience, not weakness.
For someone like Han Yi, who had reached the Infinite High Rank and possessed the Yue Guang Ancient Device, he could subdue any of the Heaven Palace realms, except for the Great Wisdom Sky.
Although Great Wisdom Sky outwardly claimed to have only two upper Heavenly Lords, which are beings of the Outer Path Realm, Han Yi suspected some secrets lay hidden. Inside Great Wisdom Sky, there might very well be peak Heavenly Lords surpassing the upper ones, corresponding to beings of the Harmonization Realm.
Dealing with the Harmonization Realm was not something Han Yi could achieve silently. He would need to exert all his strength, just as he had against the High Priest of Purgatory Island previously.
