"After I die, Arslan will be the chieftain. You all must respect him as much as you respect me!"

After falling into a black hole during an expedition, a young historical scholar from Jiangxia University transmigrates to a mysterious and primitive world and finds himself in the body of a youth named Arslan.

Waking up in a cave, he is quickly thrust into the complexities of a tribal life he's unfamiliar with. Arslan learns that he is now in the Beautine Clan, a group that has just lost their spiritual anchor, the holy fire, and their leader, the Grand Sheikh, is on the brink of death.

Amidst the confusion and grief, Arslan inherits the position of the new Grand Sheikh. With memories of his past life merged with Arslan's, he grapples with his new identity and responsibilities. He is bestowed with a mysterious "Grand Sheikh System," which offers him achievement points for completing tasks, but he initially struggles to understand and utilize it.

In a desperate attempt to save the dying old chief, Arslan uses his system to acquire a life-prolonging pill, extending the chief’s life by three days—however, the impending loss of the chief and the stolen holy fire press heavy on the tribe. In a surprising turn, Arslan manages to create fire through traditional methods, rekindling hope among the tribe and affirming his role as their new leader.

How will Arslan use his modern knowledge and the mysterious Grand Sheikh System to lead the Beautine Clan?
