Zhang Xiuya initially struggled mightily in his heart. To avoid a secret from being exposed, he started agreeing to do trivial things for Green Lotus. As the tasks he did grew in number, there was no turning back for him.
His soul gradually became twisted, until eventually, he stooped to the point of scheming against his own fellow sect brothers and sisters.
Lin Yun, listening to Zhang Xiuya's account of his downfall, couldn't help but sigh with regret. The world was indeed dangerous, and Green Lotus was certainly cunning and treacherous.
If Green Lotus had asked Zhang Xiuya to harm his sect mates from the start, he would definitely have refused. But by starting with small things and gradually getting him involved in bigger ones, he reached the point of no return, and could only be used by her.
