Gu Lianni quickly raised her hand to cover her mouth and nose. Although the gases in the Divine Fire Domain were already toxic and could not be inhaled, and she had long cast a spell to hold her breath, she still had a subconscious defensive reaction, alertly saying, "What are you trying to do?"
Seeing her distrustful demeanor, Shi Chun also rolled his eyes at her, too lazy to explain. He gestured abstractly over the incense in his hand, drawing symbols in the air with the casting of his spell, causing the rising smoke to turn and descend, drifting away after falling a certain distance.
Shi Chun pinched his index finger and thumb to measure the distance the smoke had fallen straight down, then pointed to the ground and said, "That's right, the Divine Fire should still be beneath us, approximately a hundred yards from the surface."
