Seeing the "Genius Doctor" showing an unpleasant expression, Xiao Zaihe's heart sank. He dared not insist any further, quickly replying: "Since it's a superior's order, the subordinate... the subordinate will wait here."
At this moment, he felt a sound coming from his sound transmission stone.
To achieve long-distance sound transmission, a sound transmission amulet would be used up each time. Hidden within the sound transmission amulet is a small sound transmission formation. Even the lowest grade can transmit sound within five kilometers, and the price is quite high. As for advanced sound transmission amulets that can reach over a thousand kilometers, their price is astronomical. This is why people are generally reluctant to use up sound transmission amulets unless it is very important.
Xiao Zaihe quickly took out the Sound Transmission Jade. Xiao Tiannan's thunderous roar immediately resonated in his mind, making him turn pale as he involuntarily let out a cry of alarm: "What!?"
