"The Crown Prince?" Ran Yan asked, puzzled.
Li Chengqian had been rather outstanding during his youth. In the early days of the Zhenguan era, Li Shimin often went to battle personally, and each time he did, Li Chengqian was left to supervise the nation, and he performed quite well. If this had continued, he might have become a good monarch. Unfortunately, as he grew older, he became indulgent in pleasures and often disobeyed his superiors in secret.
"I heard he has a leg disability?" Ran Yan couldn't remember which history book she had read it in, but it mentioned that Li Chengqian had a leg disability that made walking slightly inconvenient. He felt it affected his image and developed an inferiority complex, so he turned to indulgences to dilute his feelings of inadequacy.
It wasn't impossible, but to say that Li Chengqian's downfall was entirely due to a "slight leg disability," Ran Yan absolutely didn't believe it.
