Not impossible

In the dead of night, Shao Zhengyang tossed around in his bed. 

He sat up and went out of the house. The moon and stars shone above the passing inky dark clouds, painting a beautiful picture, which contrasted with how Shao Zhengyang felt conflicted inside. 

"What's wrong? You've been absent-minded the entire day!" Yu Wen Shi came out of the house, walking towards his disciple. 

Shao Zhengyang immediately stood and gave up his seat. "Master." 

Yu Wen Shi waved his hand, signaling him to sit down as he himself sat on a rock nearby. "What's on your mind?" 

~How can I sleep? It's a grave matter!~ Shao Zhengyang sighed. 

Earlier today, Lu Mingshu came up with the condition that the jade terrace line would have to stand by her side if she ever conflicted with the Zhou's.
