No, Su Chengyuan didn't hold back at all, if she wanted to laugh, she laughed out loud, without any restraint.
The other three just couldn't hold back.
An Jing's gaze instantly swept over the four who laughed and shouted: "What are you laughing at, did I allow you to laugh!"
Li Wuyu immediately stopped laughing, standing stiff as a pine tree just like Tuoba Yuyao next to him, not moving an inch.
Du Aya and Shi Shi also quickly suppressed their laughter, standing straight up with their heads up and chests out.
Only Su Chengyuan was still laughing.
An Jing, with a completely expressionless face, walked up to Su Chengyuan and looked at her with no expression as she laughed, "Is it really that funny?"
Su Chengyuan nodded as well: "Yes, it's really funny, she is also very ridiculous, and... isn't she afraid of losing her voice?"
But An Jing didn't answer her, instead she stepped aside two steps before shouting: "Su Chengyuan, step out!"
