Li Yan Island was previously occupied by Dai Mao. Due to Dai Mao's substantial cultivation and the presence of a Fifth-Rank Trap-Killing Formation, no one dared to provoke him.
However, now that a few individuals had defeated Dai Mao, the effectiveness of that Fifth-Rank Trap-Killing Formation also disappeared.
As a result, many cultivators from nearby islands caught wind of this and came to investigate the exact situation.
At first, things weren't too bad.
The lingering might from defeating Dai Mao deterred anyone nearby from coming to investigate.
But the world has no wall that blocks all winds.
Soon enough, news about the situation on Li Yan Island spread.
Furthermore, these people knew clearly that among the group, the strongest, Lu Youjiu, was not on the island.
Thus, they began to get restless, eager to seize Li Yan Island for themselves.
Though not a large island,
Li Yan Island must have had its unique allure for Dai Mao to have taken an interest in it.
