Yi Bing watched Di San, Feng Er, Liu Lin and Si Shui left. Since it was only Yi Bing's speculation that there might be a Soul Fragment on Huo Ling, possessing him so his personality changed again, Di San can't gamble on it. Even just one Soul Fragment can destroy a world.
However, they can't ignore it, too. But since Yi Bing was there to watch over Huo Ling, he left with the others to look for the other possibilities where a Soul Fragment might be.
After Di San and the others disappeared from his sight, Yi Bing glanced at Huo Ling who, like earlier, was also looking at him. "What are you looking at me for?" Huo Ling asked.
Yi Bing. "…" wasn't it you who was looking at me first? How shameless can you be lying with that guileless look on your face and with your eyes open?! Are you not afraid of retribution?! He took a deep breath to calm himself and then spoke. "Sect… master Huo. Can you remember now anything of your sect?" he asked.
