Tribulation of Heaven and Earth

I was born in a cultivating family, but I was not persecuted like in the novel, because our Long family has always been a single lineage. It is said that the things we cultivated were too powerful and we were punished by God. I always thought these were the nonsense spoken by my grandpa after he drank soju and became confused. But I didn't know until that day that everything my grandpa said was true, about dragons coming out of the sea, earth dragons turning around, and underworld happenings...
