What?
Si Ning blinked as it became clear Qiu Bai was talking nonsense but he knew some people would have jumped on to the Prince offer just to become powerful and have everything they ever wanted but Si Ning as someone that came from the twenty-one century doesn't like the idea of war at all, in this life he was already rich so he wasn't greedy, all he needed was power to protect himself and those important to him yet he couldn't refuse Qiu Bai to avoid being seen as someone that had taken Xiu's side.
Whether he takes Xiu or Xilie's side, Si Ning knew the war would be unavoidable because he had been going on for long. If Qiu Bai goes back to his country and be crowned the Emperor then all hope to avoid war would be lost.
