Yao Si was suddenly reminded of something. After Li Zheng had confirmed her identity, the first thing he had told her was: you're dead!
Death was required for a conversion! She seemed to have skipped that step, so when she got killed...
So this was just her trying to correct the sequence?
"This document shows the difference in the DNA before and after you were converted," Mu Xuan said. "Even though both show that you're a fifth-generation bloodling, there's an increase in our blood compatibility. You were a pure earthling previously, slightly different from the clones' data, so no one could detect the issue."
"Wait a minute!" Yao Si was slightly confused. "You mean I was still a human. Then why... why did I have an ability and why was I stronger?" If not, it wouldn't have remained a secret for such a long time, right?
