"Luo Su Yi, try not to face that ghost head-on," Yang Jian said. "The ghost's killing behavior started after it passed through the corridor and turned back, which it hadn't done before. In other words, the pattern of the ghost's killings lies within those actions, and during that period the only changes in the ghost's behavior were its direction and line of sight."
"Changing the direction might be useful," he continued.
Yang Jian had Luo Su Yi continue to try different approaches, and Xiong Wenwen would predict the outcomes.
Luo Su Yi nodded in agreement. He did as instructed, and didn't look back at the ghost lurking in the dark hallway behind him.
But the result was suffocating.
"It's no use. He still died," Xiong Wenwen said, revealing the outcome of his death.
Direction was not the key.
"Could it be the line of sight? We were seen by that ghost before, so..." Luo Su Yi grew increasingly terrified.
