Sixteen-year-old Lin Mo was once the most promising freshman at Ivy League College, but due to a well-planned frame-up, he was deprived of his student status and expelled from the school. At home, his father was seriously injured and bedridden, his mother was frail and sick, and his younger sister was still in her infancy. The burden of the whole family suddenly fell on this young man's shoulders. In order to make a living, he stepped into the dangerous wilderness and made a living by hunting ferocious beasts to obtain materials. From the first moment when he held the rusty hunting knife and trembled, to later on killing high-level ferocious beasts by himself, Lin Mo grew up in the blood and fire. The hardships in the wilderness allowed him to develop excellent skills. By chance, he helped the military repel the tide of vicious beasts, and he has formed an indissoluble bond with the army ever since. With his extraordinary courage, precise judgment and deep understanding of ferocious beasts, he started as an ordinary soldier, rose up step by step through life and death tests, and finally became a high-ranking military official guarding a territory. He interpreted responsibility and responsibility in his own way, and at the top, he revealed the truth about his dismissal that year.
