Whether it's a microwave eavesdropping device or a laser eavesdropping device, the most important condition for use is that it must be able to capture the resonance caused by sound wave vibrations, especially glass because it gives the best eavesdropping effect.
Unfortunately, Anton and Chris weren't able to eavesdrop on any conversations. This could have been because Bu Cunzai wasn't in this house at all, or maybe he wasn't speaking, or of course, it could have been because he was speaking from the wrong location.
Anton kept fiddling with the microwave eavesdropping device while Chris kept checking the situation in front and behind.
The long wait yielded no results, but Anton wasn't in a hurry. In fact, there wasn't anything to be in a hurry about; all he could do was wait.
Finally, Chris whispered, "A car's coming."
Anton turned his head to look back and saw a car stopping in front of Bu Cunzai's villa. After a short wait, the villa's gate opened and the car drove in.
