Wei Ting and Su Meng took out their phones and scanned their surroundings. They didn't expect that it would be even wider down there. It didn't look like it was dug out by hand, but was naturally formed instead.
There was also a gurgling underground river by the side. The water was so clear that one could see the bottom. There was nothing inside except for pebbles, and there was no sound when it flowed.
"There are traces of blood on the ground," Wei Ting lowered his head and said in a deep voice while looking at the ground.
Hearing Wei Ting's words, Su Meng also lowered her head to look. Sure enough, there was a small patch of blood where she had just stood. Although it was dry, it could be seen that it had just flowed not long ago.
"Could it be the person who disappeared?" Su Meng had a faint ominous premonition in her heart.
Wei Ting nodded and pointed in a direction. "It should be. Looking at the traces of blood, it should be in that direction."
