In the relay station, in the hall where beast gold charcoal was burning, Xu yuanshuang took out a sound-transmitting conch and activated it with a Warlock's Secret technique.
This sound-transmitting conch was an extremely precious magical artifact. As a second-grade magician, his father had many top-grade magical artifacts, but he only had one pair of magical artifacts that could transmit sound from ten thousand miles away.
The reason why it was so precious was not because of the difficulty of the weapon refining technique, nor because the grade of the array that was integrated into it was too high.
It was the most basic problem of raw materials.
It was said that creatures like the voice transmission conch had the bloodline of gods and demons, but it was very thin.
They could emit sound waves inaudible to mortals and communicate with their own kind thousands of miles away.
