Dugu Changkong's disciple was Wu Junyan.

A man who valued promises more than his own life.

When Wu Junyan was young, Dugu Changkong took a liking to him. An immortal crane invited him, and the sky was filled with a rosy glow.

In a very secret place, Dugu Changkong took Wu Junyan as his personal disciple, imparting all his skills. It wasn't the Dao techniques of the Linghe Sect, but the core techniques of the Mystic Azure Sect.
