Anticipation, what would he leave her?

that's right. The founder of The White Tiger sect was a close friend of the Shentu sect leader. Back when The White Tiger sect was first established, there was already a North Pavilion built in the sect.

and after the Shentu sect leader passed away, he left behind a will saying that if one day, a disciple from the north gate of the sky Mansion could open the North Pavilion and obtain his legacy.

then The White Tiger sect will do its best to protect this disciple and support the north gate of Tianfu from that moment on. We will share honor with the north gate of Tianfu and live and die together.

however, as long as such a disciple doesn't appear at the north gate of the sky Mansion, The White Tiger sect will not be able to help the north gate of the sky Mansion. This is the main premise. Beitang kun explained.
