The Red Race had subjugated the Nanni Nation hundreds of years ago, but during this long period, they had not advanced further into the Wood Dynasty's territory. One reason was that they themselves were not yet unified internally, and the other was to find a safe sea route.
Now, the sea route has finally been found. Although it is not foolproof, sending thirty warships, at least twenty can reach the Nanni Nation, which is enough to launch an attack across the sea.
They call their continent "Heavenly Kingdom," and beyond it is all wilderness, a land that can be conquered by divine decree.
The deity they worship, known as the "King of Time and Space Conquest," has frequently bestowed miracles in the Heavenly Kingdom, presenting an entire set of Cultivation systems that can reach the Power of Nine Mountains, equivalent to the Ninth Great Realm of a cultivator!
However, like in the Wood Dynasty, for some unknown reason, believers above the Power of Six Mountains are very rare.
