Jiang Ning was puzzled: "I can understand leaving Princess Zhenming here, but why also keep Prince Xinhai?"
"I think compared to the promise to Prince Xinhai, the weight of the person is more important."
"You want to keep Prince Xinhai as a hostage?"
"Yes."
"That's impossible." Jiang Ning shook her head, "The Monarch of Silla only has Prince Xinhai as his son, if you detain his son, will the Silla prince let you off easily?"
"If he doesn't, what can he do?"
"Collaborate with the Prairie Cavalry, I guess. But I believe the Imperial Court must have a solution." Jiang Ning picked up the clamps, opened the cover of the fire basin, fiddled with them a few times, and clamped out a roasted sweet potato.
The sweet potato was actually what would be called a red yam in later generations. Jiang Ning could only follow the local customs and call it by its local name.
