Su Wuming had always been a man of few words, and Han Zheng had actually grown accustomed to that.
So just now, Han Zheng had been focusing on the mural the whole time and conversing with Yan Xuankong, which led to some neglect of Su Wuming.
But who would have thought that in such a brief moment, Su Wuming would have disappeared? Something wasn't quite right.
Just as Han Zheng was about to step forward to look for Su Wuming, he suddenly felt that something was amiss.
Han Zheng looked down at his feet then glanced around, his expression subtly changing.
The cave that led to the underground river they had come through had vanished.
The footprints left by Cui Zeyuan and the others on the ground were gone, and so were the footprints made by himself and Su Wuming upon entering.
It now seemed likely that it wasn't Su Wuming who had disappeared, but Han Zheng himself!
"What's going on here? Old Yan, have you noticed anything wrong?"
