Guilty

Master Lu was not sure what to say. He knew that Lu Nanfeng would have never wanted to show this to Di Zhiqing if Liu Xiulan's actions had not gone over his bottom line.

Lu Nanfeng was aware of how much Di Zhiqing liked Lin Xiulan, so although he broke off with her, he never tried to make things difficult for her, nor did he explain himself in front of Di Zhiqing. 

However, this time Lin Xiulan had truly crossed the bottom line of what he could accept. He was furious about her repeated attempts at separating himself and He Lixue, and he could not take it any longer.

At the same time, she had clearly been bad mouthing He Lixue in front of Di Zhiqing, and now everyone knew that Di Zhiqing disliked her future daughter-in-law. This was not fair to He Lixue, nor was it fair to Di Zhiqing. 

Master Lu sighed. He knew that Lu Nanfeng had wanted to keep a semblance of cordiality with the Lin family, however this time she had truly dug her own grave.
