Zhang Tie's meritorious deed in the western theater of operations could really glorify his forebears.
According to the regulation of Taixia Country, people couldn't be awarded a title of nobility unless they had killed demons. The title of nobility acquired by Zhang Tie's dad was almost the only one that could be awarded by Xuanyuan Hill. Being inferior to prince, duke, marquis, count, viscount and baron, this title of nobility was not awarded according to the heavenly fortune ranking. It symbolized great honor and was used to award those people who had made great contributions to humans in the holy war although having not killed demons on the battlefield.
Zhang Tie's dad and mom were both awarded which indicated that the country appreciated them for having such a great son.
