On one side, they were also surveilling them, ensuring they didn't do anything untoward during this process.
Before leaving, Xu Heng put one hand into his pocket and pressed the button on an object inside.
Deeper inside, Xu Heng was worried that if he pressed the button again, it may not function as intended, or the signal may not be received by those outside.
Even now, Xu Heng was somewhat anxious, afraid the signal he was transmitting would not be picked up.
But soon, a smile appeared on Xu Heng's face. He felt the button in his pocket vibrate three times consecutively—it was a sign that the signal had been sent and received by the other party.
Wang Ye glanced at Xu Heng and noticed that the smile on Xu Heng's face was a bit ghastly, but also somewhat relieved, as if he had let go of many things in that moment.
And with that, he had fewer concerns to worry about.
Could it be that Elder Xu contacted someone outside?
