How to interpret Andrew's sentence "Nothing, Doctor" in Flying Life?

This sentence should imply that Andrew will raise Zhang Fei for Zhang Chi after his death.

Zhang Chi raised Zhang Fei, and only Zhang Chi raised him. However, Zhang Chi finally flew off the cliff, so Zhang Fei was neglected after Zhang Chi's death.

Looking at this line again, I think it's very likely that Yin Zheng and He Sui had a problem with having children (maybe they didn't want to have children, or they wanted children but didn't give birth in the end).
