At that time, the grain was sent in Chu Heng's name.
However, there was a lot to be explained in this. Chu Heng was the official in charge of transporting the grain. He could say it was his own donation, or he could say he was delivering it on behalf of the Emperor.
After Chu Heng had visited the palace, he returned with a reward, which included silver rewards, some more than the silver Ye Muyu had spent on the grain.
Ye Muyu understood that the previous grain was sent in Emperor Xuanming's name, and the Emperor was very reasonable, returning all the silver back to her.
Ye Muyu didn't feel the slightest bit of heartache now. Originally, she just wanted to help Chu Heng solve a problem, but now the Emperor was very principled, returning whatever silver the family spent on behalf of the imperial court each time.
She wouldn't have to rush to earn silver anymore.
