Chapter 427: The Method to See Through Ghosts

On one side, Wan Yunrong and Miao Yu followed Wu Xiaonan, while Xu Huo and Chu Yuan were in charge of checking the corridors since there were so many rooms in the lab. Zhu Rumin could be hiding in any one of them.

Chu Yuan used chewing gum, which was actually a prop, to stick the illumination lamp on the ceiling of the corridor. "This way, if someone passes by, they might be exposed by their own shadow," he said.

Xu Huo did not express agreement or disagreement, simply cooperating with his actions.

"How did Gan Qing figure out that Zhu Rumin was the 'ghost'?" asked Chu Yuan. "The five of us staying together couldn't tell."

"It might be because of the glass window," Xu Huo suggested. Last night, he and Chu Yuan had seen the Ghost Shadow through a window, whereas Gan Qing, who had chased Chang Chengyong out, just happened to stand behind the door, separated by a pane of glass.
