Zhou Xi, alongside Yue Feng, was a Heaven-Talented figure, the king among Warriors at the Warrior Realm.
If Chu Hao and Yuan Tiangang could be called the youngest kings, then Zhou Xi and Yue Feng were the young kings, having risen about a decade before Chu Hao and the others on the current Fledgling Dragon List.
As time weeded out the weak, many once-celebrated talents from the Fledgling Dragon List had fallen or were outpaced by others and eliminated. Thus, after about a decade, at most only one third of the talents from the same list could remain in the same position.
When it came to the Warrior Realm, because the step to War General was incredibly difficult to cross, taking often more than a decade, talents spanning a decade in age were grouped into the same era.
