Yu Xi suddenly fell into a coma, her face showing signs of death.
The Yu Kingdom sought help from Immortal Mortal Island, but mortals not yet on the island were not under its protection and thus, assistance was out of reach.
As her brother, Yu Chen, upon learning from the State Preceptor that an immortal treasure that could save Yu Xi could be salvaged from the Extreme Immortal Sea, spent a whole year leading people out to sea, salvaging from its surface.
A year's time is not long for a cultivator.
But for the mortals of the Mundane World, it marks the revival of spring and the dormancy of winter.
And the seemingly calm surface of the sea did not guarantee eternal safety.
Apart from fishing out delicious fish and shrimp, the immortal-level treasure divined by the State Preceptor wasn't even seen.
So, when they saw Lu Xingyan and his companions emerge unharmed from the deep sea, Yu Chen and his people's first reaction was that they had encountered a sea demon.
