This person is Huang Zu, the Prefect of Jiangxia County in Jingzhou.
Huang Zu has been severely overlooked in history. It can be said that because of his presence in Jingzhou, Jiangdong repeatedly failed to conquer it.
He was a naval commander even more formidable than Gan Ning. If Cao Cao hadn't killed him back then, Huang Zu would never have agreed to Cao Cao chaining ships together.
The Battle of Red Cliffs might have been rewritten, and Boss Cao could have unified the Han Dynasty with that single battle.
