Upon reaching them, Mark stared at his sister and lectured her in a calm tone, "Your father had lent me this place, Princess Shang. But, that doesn't mean that you can do whatever you can and expect that no one will speak against you.
This is supposed to be a ground where the weapons are demonstrated. Since it is big enough to train, one can spar if they want and I have no issue with that. However, if you intend to kill each other, please do elsewhere.
I held back earlier because your brother is with you but it looked like you take everything for granted and don't care about the consequences."
Mark indeed doesn't want to disappoint a valuable client like the second prince but he couldn't turn a blind eye when his temporary property was going to be damaged because of these two imperial children, especially Shang Jiao. Moreover, he was also a little bit irked by how the princess went back on her promise about tagging along with Lin Xue.
