A modern college student travels to a cultivation world and becomes an ordinary cultivator with mediocre aptitude, trapped in a mine of the demonic sect. A jade pendant connects him to the official forces of his original world. Relying on technology and supplies, he rises rapidly and crafts magic artifacts with modern techniques. He exposes the truth that the so-called sect is actually a lair of savage beasts. Allying with forces from his homeland, he subdues the beasts, shares cultivation resources, prepares for the upcoming great war, and sparks a massive counterattack of the human race.
