"What did he leave behind before he left?"
Li Zhian took out a key. "If he doesn't return, he told you to find what he left behind."
Cao Changjing accepted the key from Li Zhian.

Li Xuanxiao had already been guarding this place for three months.
According to Li Zhian, the entrance to the Extreme Cold Secret Realm only opened once a year.
Li Xuanxiao spread out his Spiritual Sense and deployed his various puppet clones, ensuring he would not miss the opening of the Extreme Cold Secret Realm.

None of her former vitality remained.
The bluish-purple veins on her wrists had already spread across her entire body, and even her fair neck was now covered in them.

That was the sound of Tribulation Crossing Stage spiritual power being corroded, like glazed glass shattering.

The snow falling around them turned into snake-scale-like crystals before
