Chu Yetianhong is an Ancestor-level character to the Chu Heavenly Clan.
Chu Yetianhong was an unprecedented talent in the Lower Realms solely off the fact that he managed to ascend 8 steps of the Nine Levels Heavenly Lightning Steps. Chu Yetianhong also activated 5 stages of the Chu Heavenly Clan's Bloodline Altar.
However, Chu Yetianhong's most admirable feat was the Chu Heavenly Clan's reliance on his martial might to aid the Chu Heavenly Clan's ascent out of the Ancestral Martial Lower Realm to the Hundred Refining Ordinary Realm.
In addition to that, Chu Yetianhong even lead the Chu Heavenly Clan to battle their way into the Great Chiliocosom Upper Realm and even established their status as the Ruler of this Upper Realm. As a result of this, the Chu Heavenly Clan became the Overlord of several Lower and Ordinary Realms as a result of this.
Unfortunately, Chu Yetianhong succumbed to an illness as a result of overexerting himself. However, even though tens of thousands of years have passed since Chu Yetianhong's conquest of the Great Chiliocosom Upper Realm, the Chu Heavenly Clan still remains an overlord of an Upper Realm. This is a testament to Chu Yetianhong's martial might and therefore the effect his deterrence has.
