At the time, Black Demon and his group had just escaped the pursuit of that Hundred-Thousand-Year Soul Beast in the Star Dou Forest, only to encounter a Spirit Hall Soul Saint squad after emerging.
With no other choice, they split into two groups and fled separately. Black Demon had only two options before him: flee to the Star Luo Empire, or flee to the remaining kingdoms and duchies.
The Star Luo Empire was militarily powerful and had never tolerated Fallen Spirit Masters like them. If Spirit Hall informed the Star Luo authorities that Fallen Spirit Masters had fled into their territory, whether it was the imperial family or the major sects of the Star Luo Empire, they would send people to hunt them down. Their lives would not be easy there either.
But if he fled to the other kingdoms and duchies, the advancement of his Blood-Devouring Nether Fang would be delayed again. After all, the continent's renowned Soul Beast gathering grounds were all located within the Two Great Empires.
At that moment, Black Demon remembered the Nether Vine Soul Douluo in the Tianyang Mountain Range. Relying on the unique traits of his Martial Soul, that fellow had dug tunnels beneath the Tianyang Mountain Range and established himself there for more than a decade.
The most dangerous place was often the safest. Over all these decades, no one from Spirit Hall had discovered that a group of Fallen Spirit Masters was hidden beneath the Tianyang Mountain Range.
Thinking of the abundant Soul Beast resources in the Tianyang Mountain Range that could help the Soul-Devouring Nether Fang advance, as well as having the Nether Vine Soul Douluo as a companion, Black Demon simply headed straight for the Tianyang Mountain Range.
To thoroughly mislead the Spirit Hall pursuers behind him, he deliberately
