Life-and-death Immortal Aperture!

The Gu formation in Snowy Mountain blessed land was not set up by Old Ancestor Xue Hu.

He was a rank eight great expert, but he could not set up such a Gu formation.

To set up this Gu formation, Old Ancestor Xue Hu personally went to ask the number one formation path Gu Immortal in Northern Plains, Sun Ming Lu, for help. Sun Ming Lu was a righteous path Gu Immortal, he had a firm personality and refused to cooperate, Old Ancestor Xue Hu knew that he could not be forceful, he put down his status and asked him for help numerous times.

After seven invitations, in which Old Ancestor Xue Hu talked about Lady Wan Shou at the final time, Sun Ming Lu finally was convinced.

Even though Sun Ming Lu was someone with extremely firm will, he treasured love and loyalty. Old Ancestor Xue Hu was setting up the refinement path Gu formation for his beloved wife, their love touched him, therefore he helped.
