How? If the novel is accurate, so please correct me if I'm wrong, he was killed to keep the army from rioting over lack of food?
For the record, can't find him in Rafe's tome though that isn't always an answer to real or fictional but can't find him in any translated sgz, ZZTJ and encyclopaedia says he is fictional
“You, are a rebellious son who abandoned his father. You are a cruel brigand who murdered his lord. How can Heaven and Earth put up with you for long? And unless you die soon, how can you face the sight of men?”
