Two modern souls accidentally fell into the wilderness of the Xia Dynasty after the loss of Taikang. One became Yeluyue, a young man from the Youqiong clan, and was responsible for the "Chinese Fire System" to preserve the fire of civilization in tribal disputes; the other turned into Tuoba Ye, a hare at the foot of Tushan Mountain, bound to the "Spiritual Pet Evolution System", struggling to survive in the jungle.
When a boy who maintains a system meets a rabbit who can think, the boundaries between humans and animals are blurred in the wilderness. One of them uses the power of the system to forge bronze and unite tribes, and the other relies on the ability of evolution to discern crises and communicate with all things. In the troubled times of Hanzhuo and feudal lords, this strange pair will use dual systems as their blades and wisdom as their shield to find their own way to survive in the wilderness above the Xia Xu.
