Shen Yanning travels through the primitive beast world, and right after landing, she hugs the thigh of the strongest black tiger, Hujin. The black rabbit jade pendant awakens the golden finger to survey the terrain, clear wasteland, and engage in infrastructure. Cold infrastructure heroine vs. hard-mouthed, clingy, ominous black tiger beastman. She stores grain and builds houses, leading the tribe to survive; he hunts and protects his wife, repelling all competitors. Kicking away the prejudiced old tribe, the two build a new home together.
