Shangguan Wanru learned about the Imperial Court's preparations for a military campaign against Nangong Country several days later. She discovered this while looking for Prince An in his study and overhearing his conversation with Shangguan Ruixi.
"The first batch of grain and provisions has already been covertly transported out. The roads are slippery due to the snow, making it unsuitable for further transportation at the moment. However, once the weather warms up and the ground no longer freezes, you must hurry to send out the second batch of provisions. Be careful not to be discovered," Prince An said
"I understand, father, don't worry. It is the end of the year now, and there are many merchants transporting goods; each team is quite long. We also disguise ourselves as a merchant team, and no one will be suspicious of us. Alas, if it wasn't for Yijin giving birth, I would love to lead an army to attack Nangong Country," replied Shangguan Ruixi.
