"Sol, why are you stopping so suddenly? Is there any danger ahead?" Tea asked him as he suddenly stopped walking while looking to the side.
They had been traveling in the underworld for two months and they had got closer to their destination but the closer they are to the gate of the underworld, the more dangerous it becomes, the number of strong creatures increases as they get closer.
There were multiple instances where he stopped suddenly in their journey and told Tea to hide her presence while hiding his own presence, they would be detected by a major demigod if they did not and it would be the end of them.
In the long run, Tea did not need him to tell her and she already hid her presence whenever he stopped walking, she did not want to take any chance and attracted a possible danger.
