"If that's the case, he wouldn't bother to leave marks specially. So, he just wants us to enter the tunnel cautiously..." While speaking, Ling Mo slowly moved closer and then groped to find the wall. He quickly located the position of the mark through the touch of his fingers... The wall originally had layers of mucus and moss, and after being burned, it left a layer of rough particles. Ling Mo scraped a bit off with his fingernail, and even before bringing it close to his nose, he already sniffed a faint smell of burning.
"Host Xu," Ling Mo extended his finger, "come and smell it, see if you can analyze the time elapsed since the burn."
"Hmm? Okay."
In the darkness, a breath of cool air quickly blew over Ling Mo's fingertips. This process lasted for less than two seconds, but when Xu Shuhan withdrew, Ling Mo distinctly felt her breathing become much more rapid, and at the end, there was even a kind of reluctance...
"Did you discover something?" Ling Mo asked quickly.
