Feng Qingxue's grandparents should be in this world in her current life, since the grains she anonymously sent them had not been returned.
It was not known whether they received them or if the grains were confiscated by someone else.
Regrettably, since she joined the army, she no longer had such freedom and didn't dare send them grains anymore, fearing that it would give her away. However, while she was sending letters to friends and relatives a while ago, she took the opportunity to send one to them as well, subtly warning them to take precautions.
The language used was so cryptic, entirely written in Classical Chinese, which could not be understood without certain knowledge.
In this era, after all, the majority were illiterate, and even among the literate, a sizable portion could only understand vernacular Chinese and were no longer as familiar with Classical Chinese as before.
As for her maternal grandparents, they were not yet married.
