The Foreign Realm, in the northwest.
This was a boundless plateau, where rolling yellow peaks joined together to form majestic mountain ranges.
At the center of these ranges lay an ancestral vein, connected to every mountain range on this limitless plateau, where the spiritual energy of heaven and earth and vital essence gathered.
Dense undying aura flowed here, equivalent to the immortal aura of the Nine Heavens and Ten Earths, making this place seem like an immortal paradise.
Before long, a slender, graceful figure appeared here. It was Yun Ying.
"What sacred ground. The Undying Kings of this realm truly live the best lives."
Little Purple marveled. A place like this was occupied by a single Undying King, with no second Undying King within several hundred thousand li.
Clearly, the Undying Kings of the Foreign Realm were all like this, each occupying a cultivation sanctuary of the very highest caliber in the Foreign Realm. Even those who had founded Imperial Clans were no exception, and could also bless their descendants with its benefits.
Yun Ying's first target was an Undying King who had not founded his own Imperial Clan. He cultivated alone in seclusion here, and his name was Yuan Ke.
Moreover, Yuan Ke's strength ranked among the most ordinary Undying Kings, and he was also one of the eight Undying Kings who had attacked Yun Ying back then and forged a karmic tie with her.
After arriving here, Yun Ying easily pinpointed Yuan Ke's location.
Although an Immortal Dao Formation covered this place, it was not particularly powerful. To an Immortal King Giant like Yun Ying, it was as good as nonexistent.
Only Undying Kings who had studied the Formation Dao and achieved something in it could lay down stronger Immortal Dao Formations, powerful enough to affect quasi-undying kings.
