Overacting

"If the spy grim reapers have a way to hide from the Conferment Seal's monitoring, then Di San wouldn't ask me to puncture the Conferment Seal on his body." Yi Bing said.

Yang Jie nodded in agreement since he thinks that this also makes sense. "Then, the mole…" he muttered.

"It should be one from Di San's team that time – Feng Er, Liu Lin, and Si Shui." Yi Bing said. His face is serious. "We can rule out Feng Er." He said.

"Why?" Yang Jie asked in surprise.

"She has a grudge against the secret organization for 'killing' Lili." Yi Bing answered. "Even if she can fake it, but Lili won't fake it." He said. Before Yang Jie could speak, he continued. "The both of them talked to each other as Gu Lin and I arranged for us to sus out Feng Er. So, it is not her." He explained.

Yang Jie now understood. "Then… either Liu Lin or Si Shui?" Yang Jie asked.
