As soon as he thought about it, he did it.
He Song, holding several Thick Earth Amulets, left the cave with a solemn expression.
However, the moment he left the cave, his expression suddenly relaxed.
Not far away, a sound-transmitting paper crane stood at the periphery of the Illusion Array, seemingly unable to find its target.
Spirit power flowed through the paper crane, emitting a faint light, but it remained motionless, like a lifeless object.
He Song quickly reacted.
The Sound Transmission Skill, after exchanging breaths with a friend, only needed to release a paper crane or a bird to contact the other party. It was the preferred skill for Qi Refining stage cultivators to communicate over long distances.
Of course, if the other party was within a defensive array or had hidden their breath with the Breath Concealment Formulas, the Sound Transmission Skill would not be able to locate them and would stay where their breath disappeared.
