In fact, Zhou Wen basically couldn't hear Zhang Yuzhi. Along the way, he tried to get used to the world's sounds Truth Listener brought to him.
However, this was just too difficult. Ignoring the fact that he could receive all kinds of the sounds, Zhou Wen could only occasionally hear the right channels even if it was a sound coming from right in front of him.
