Leaving behind the eccentric merchant Lao inside the small cave hideout after having successfully recruited him to join the sect and handed over the things Elder Dust Fairy had asked him to give him so he could properly be identified by the Domain Lord Realm Elder who would be showing up to take him back to the sect, Chu Yang soon found himself at the shore of the river where the entrance to the tunnel leading into the cave hideout was located.
Because of the relatively secluded location next to the river that the hatch was located in, he managed to easily make it out without being noticed by anyone in the process.
Of course, one of the reasons why he wasn't noticed was also because most of the cultivators normally on the nearby streets had long since left, either to search for weaker cultivators to use for exploring the ancient ruins or to escape from becoming a scout of these stronger cultivators.
