Chu Yun didn't know what his face showed, but whatever it was it made Gu Wei chuckle. The truth was that Chu Yun didn't expect Gu Wei to have any intense feelings for anyone besides his children. He certainly had never seen him display that level of care for anyone who wasn't Xiao Zai.
Gu Wei must have really liked the Queen Consort, because it was a lot easier for him to have killed Qin Ming -- if not immediately after the Queen Consort's death, then at some point during the years she spent out of sight in the Cold Palace. He would have saved himself a lot of trouble. But he hadn't done any of this just to get rid of an enemy.
He had completely destroyed her, in memory of his friend.
Chu Yun wondered if he felt closer to the Queen Consort when he visited Concubine Qin and saw her like this. Did it bring him peace?
