Scalpel: Building an Empire in the Rainforest

Top surgeon Chen Yuan crashes in the Amazon rainforest and discovers that the future corporation 'Blackstone' is conducting inhumane 'experiment field' tests there. Using modern medicine and scientific knowledge, he leads the primitive Eagle Feather tribe, employing scalpels, homemade gunpowder, and reverse-engineered future technology to transform from prey to hunter, launching a counterattack that overturns the future colonization plan and builds a rainforest empire.
