Although Ye Xuan's condition wasn't as serious as Shen Changling's, he felt as though his mind was about to explode as well. He felt his heartbeat gradually increase with that inexplicable sound. It almost felt like his heart was not his own.
The sound became long and drawn out. If one listened carefully, one could even detect a rhythm to it. The inexplicable rhythm lingered in the air, giving the impression of a beating heart!
Ye Xuan was shocked by this thought. How could it be a heart?
However, once he considered it, he could not dismiss this possibility.
Due to the pain, Shen Changling's facial expression became even more twisted. Even though he had sealed off his five senses, it was not a permanent solution. Soon, it lost its effect. The sound traveled along the blood-red lines and soon enveloped the entire area.
