Disguise

The man was covered in wood-like material, they could not see his body but they could conclude that he was a human from his posture and bearing.

Sol and his group did not show themselves to the man and decided to hide first and decide what to do with the man.

"let's go and ask him if he knows where is the city," Jennie suggested, She was about to go first when Sol grabs her by the hand.

"No, we don't know if he comes from the mortal realm like us or actually soul of the dead, we could not take the risk of exposing ourselves," Sol reasoned.

"that's right, we should disguise ourselves first, and it would be suspicious to ask him where the city location is," Tom added.

"The city should be near since he is cutting a tree here, we could just continue to follow the river," Tea said.

Everyone else agreed with her logic, meeting a person there means there was a city nearby, the closer they were to a city means that they would meet more people.
