The Nine Mystic Mountain of the Western Frontier and the White Tiger Clan of the Southern Wasteland were allies.
Back then, when Tuoba Cheng succeeded to the position of the Nine Mystic Sword Sect's sect master, the White Tiger Clan sent over the essence of the White Tiger bloodline.
The two factions had a lot of interactions after that.
Before Han Muye came to the secret realm, Tuoba Cheng instructed him to help the White Tiger Clan as much as possible.
The White Tiger Clan was considered the strongest among the demon race, and they were more magnanimous in their actions.
It was precisely because of this that the other large clans viewed them as an enemy.
According to the investigation of the Nine-Tailed Cat Clan, the White Tiger Clan was besieged by the Yellow Lion Clan and the Purple Leopard Clan in the secret realm. They had suffered considerable losses.
