บท 643: Chapter 642: Unexpectedly, Mu Chengxi was treated as a test subject

"However, in the Biological Laboratory, my authorization was too low, and I didn't have any data to refer to, so I began conducting research on my own."

Wen Xin squinted at Sun Ning; she didn't quite believe what Sun Ning was saying. She knew once someone entered the Biological Laboratory, they would never have a chance to leave, let alone live freely in Independent State.

Meeting Wen Xin's skeptical gaze, Sun Ning smiled lightly, "I know you don't believe me, but it just so happened that I found a hidden passage in a long-abandoned lab and seized the opportunity to escape from the laboratory."

"When I first joined the biological research, I wasn't using the identity 'Sun Ning'; instead, I used the name of a young apprentice of my mentor. After escaping, I resumed my real identity, which naturally means nobody knows what happened. Little princess, you are the only one!"

While speaking, Sun Ning displayed a rather proud demeanor, as if boasting about his own cleverness.
