Just after their father's first-seven memorial service, elder sister-in-law Li Ling colluded with elder brother Lin Chuan to forcibly coerce a family division in the capacity of the eldest son, monopolizing the family property and driving mother Zhao Cuilan, Lin Yuan, and younger sister Lin Fang to the abandoned adobe house in the back mountain. In a barren year lacking grain, Lin Yuan firmly remembered his father's entrustment, shouldered the heavy burden of supporting the family, resolved to enter the mountain to hunt, and unexpectedly awakened the beast servant system. Starting from contracting an owl, he successively subdued flying birds and running beasts such as lynxes, brown bears, golden eagles, and otters, with beast servants obeying orders in the sea, land, and air. Relying on the coordinated hunting of his beast servants, Lin Yuan led his mother and younger sister to eat meat at every meal, completely reversing the bitter days.
