Huo Ling fought with Yi Bing… and lose… again. He is just a pitiful soul. He wants to know about his death, thus he can only do Yi Bing's bidding.
And so, he faced the wall. Yi Bing was waiting for him to pass through. "… can I not?" Huo Ling asked as he turned to Yi Bing.
"There're no wards in this unit." Yi Bing said. That means, Huo Ling has to pass through the wall.
"What if I found a dead body?" Huo Ling asked.
Yi Bing frowned, started to get pissed. "You think too much. Just go in!" he snapped at him.
Huo Ling jumped out of fright and his soul moved without his will. Thus, he passed through the wall and it seems that he… didn't think too much. There's really a dead body! And it's not just one, but three! "AAAAAAHHHHH!!!" he screamed and covered his eyes as he passed through the wall again and went back to hide behind Yi Bing. "More dead bodies!" he reported to Yi Bing.
