" You ..are you trying to say that the person who killed our aunt was …" Zhai Tianyu's eyes widened, it wasn't that he hasn't thought about it, he has but the thing was that he was willing to believe that something like this was impossible after all, his aunt's in-laws and close friends were really good to her but now he realised that those people were no different than the people in the imperial palace while smiling at their faces they all were waiting for the right time to kill his aunt. 

" But that is impossible," Zhai Cheng was the first one to refuse the notion as he looked at Liu Hui Ying, he wasn't willing to accept that the person who killed his aunt was someone whom he trusted, how could someone throw dirt in his eyes and kill his aunt right under his nose? It was impossible!
