Blood Rain!

After the Ba-Serpent was led away by their patriarch, the entire clan began to migrate to the Northern Kingdom. They had raised many black snakes with the bloodline of the Ba-Serpent, as well as green snakes, other than the Ba-Serpent. Although these snakes were not as powerful as the Ba-Serpent, they were very big and swam very quickly because of the Ba-Serpent's bloodline. Every time the Ba-Serpent Clan Patriarch led the Ba-Serpent to battle, they would bring those snakes and quickly follow.

It was so that they could quickly plunder the fruits of victory when the Ba-Serpent occupied another country.

Moreover, as a tribe that worshiped the Ba-Serpent, the members of the Ba-Serpent clan had almost arrived at the Northern Kingdom when the Ba-Serpent fought Hu Jiujiu in the Imperial City.
