A modern scholar, Mu Feng, accidentally transmigrated and upon waking up became the Great Chieftain of the Jiang Tribe. The sacred fire was snatched away, Grandpa was heavily injured, food supplies were completely cut off, and the powerful enemy Manglong Tribe eyed them covetously. Amidst the desperate situation on the verge of the clan's extermination, Mu Feng relied on modern knowledge and the Great Chieftain System to drill wood for fire, fish in the ice lake, dig wells and build walls, domesticate chickens, sheep, and wild boars, discover wild vegetables and corn, and manufacture bows, arrows, and pottery. With his wisdom, he beat back powerful enemies and led his kinsmen from hunger and cold towards stability and prosperity. However, the myriad primitive tribes lurked around, and crisis gradually approached. Mu Feng had to lead the Jiang Tribe to continuously grow stronger, ignite civilization amidst blood and fire, and establish a powerful tribe belonging to himself.
