Let's enjoy the festival, great evil dragon!

While the demon who snuck inside the old dragon is having a bit of a hard time finding the “hidden darkness“ inside his host, Lingzi and her dragon prepare to leave town. But with the festival to worship the saint of the water just around the corner the saint asks the duo to stay a few days longer until the festival is over. The prolongued stay, however, gives the demon additional time to search for darkness in the old dragon's heart.
