Haha it is indeed confusing. The story of Soul Land- Legend of the God's Realm is a story after the story of Combat Continent I and Combat Continent II when the characters ascended to godhood and left the lower realm which is the mortal realm. The story can be found in this site, just try to paste the title. It's really short though and still ongoing.
It's this one:

His sister only gave him her dragon spear, but he received some powers from the golden dragon but it was too strong which was the dragon intention hoping that it would kill him and make Tang San go mad. So tang san used up most of his powers to seal it so he can fully absorb it slowly as he grows up and I believed yuhao was the one that send him to the lower realm
Spoiler alert!!
So I read(?) the Soul Land- Legend of the God's Realm Raw (though I didn't understand the words), the main character here is actually the Son of Tang San and Xiao Wu. Another thing is that the female protagonist of the Combat Continent II is his sister, the goddess of the butterfly. Apparently, the God's realm had war and shit happened. They had no choice but to send the child to the Lower Realm, the Douluo Continent. Before sending him though, his sister passed a power to him which was sealed. And if I'm right, the battle of the gods had something to do with the dragon god? Pity I can't understand the words ( ̄∇ ̄"). Though, whether the god's realm was destroyed or not is still unknown to me but I think it was destroyed. I also wonder what's the connection of the death of the antagonist from the God's Realm and the awakening of the Dragon King here.
PS: I can't still believe it that the main protagonist of the CC II is the god of emotion. Why emotion of all things?
PPS: the gods and goddesses
CC I:
Tang San- Sea god
Oscar- Food god
Ning Rongrong- Nine-Color goddess
Dai Mubai- War god
Zhu Zhuqing- Speed goddess
Ma Hongjun- Pheonix god (This guy seriously had the major change. 180 degree. Plus points to his looks though. 100/100)
