Lin Wu met with an accident.

Mou Chuan explained to her, "Eighteen years ago, a meteorite fell in Lingnan. At first, it just brought some natural disasters, and the thirty-six strongholds thought that was the end of it. But gradually, they discovered that the villagers began to go mad and harm people for no reason, and domestic animals, as well as wildlife, would mutate. Newborns were mostly deformed. They felt something was amiss and, after several investigations, they found the location of the meteorite."
