In the distance, Qian Ying saw Zhou Zixing standing behind the building without moving for quite a while and could not help sending a voice transmission. "Elder Zhou, did you insert that horn?"
He was roughly a hundred meters away from Zhou Zixing. Normal speech would work, but he would have to shout. At that distance, if he spoke too softly, Zhou Zixing might not be able to hear him clearly.
But shouting would damage his dignity. Voice transmission was far more convenient, and it consumed very little Xiantian power.
After hearing Qian Ying's voice transmission, Zhou Zixing explained the situation.
After hearing it, Qian Ying considered it briefly before transmitting again. "Check whether it can be turned after insertion, or whether it needs to be pressed or something. Try everything. Maybe the method was wrong. If none of that works, pull out the horn and insert it again. Perhaps you moved too quickly just now, or perhaps the timing was wrong."
Qian Ying recalled that the button in the hollow had only appeared during the day and vanished at night. Thus, he considered that perhaps the timing of insertion had been wrong, or perhaps the horn had been inserted incorrectly.
In any case, this building had existed for a very long time. Perhaps inserting the horn had failed to trigger the mechanism inside it. It would not hurt to try a few more times; perhaps something would happen.
"Alright, I'll try again!" Zhou Zixing felt that was possible as well. He stepped closer, intending to test it and see whether he could provoke any reaction.
However, before Zhou Zixing could even reach out, he suddenly heard a faint sound!
Zhou Zixing heard the noise but could not find its source, nor did he know what had made it. He
