On Chu Xuan's side, after various attempts, he also made the old ghost swear on the Six Souls Banner. Whether it worked or not, he couldn't just swear without the old ghost doing so.
The old ghost hesitated for a moment but ultimately obeyed.
Although the Six Souls Banner didn't react, seemingly without the function to bind oaths, Chu Xuan felt a bit more at ease and asked the old ghost to fully enhance his speed.
The old ghost then applied the "Ten Thousand Miles Wandering Soul Curse" on him, temporarily transforming into a soul for flight. The speed was much faster than Chu Xuan's own Sword Flight.
Despite this, the people from the Li'an Demon Sect departed first, and Chu Xuan was delayed for quite some time without any means of long-distance tracking, only able to ask the old ghost for directions and headed towards the Demon Sect's mountain gate.
