According to Dragon Saint's slow narration, Jiang Chen began to understand the truth of that era.
Back then, when the human forces left by the Dragon Clan learned that the Dragon Clan had been targeted by major forces and sealed on Dragon Island, the vast majority chose rebellion.
These people either declared themselves as sovereigns or joined the doctrines of other forces.
Only one top martial arts family among the remaining forces did not betray the Dragon Clan.
The doctrines of major forces united to hunt down the martial arts family that did not rebel against the Dragon Clan. This family was once the representative of Dragon Island among humans and was taught a set of cultivation techniques suitable for humans by the Dragon Clan, and everyone from the major forces wanted that cultivation technique.
That war was the first battle after the migration of major forces, ending in the defeat and concealment of that martial arts family.
