Wen Xin kicked the pebbles beneath her feet with a distracted motion, her head hung low as she watched the stones, answering Mu Chengxi's words without much thought, not sure herself how much time visiting Old Dong would take.

While Wen Xin and Mu Chengxi were chatting idly, Wen Xin's phone vibrated with a call from Sun Ning.

"There's something, I want Sun Ning to treat Old Dong, and now Sun Ning is calling me. I'm going to take his call first and will talk to you later."

Wen Xin didn't wait for Mu Chengxi's response. She hung up on him immediately and dialed back Sun Ning's number to return the call.

"Little princess, your Biological Laboratory is way too comfy, isn't it? Coming to join you is definitely the right choice!"

Sun Ning excitedly started talking as soon as he picked up the phone.
