The graduation ceremony took a sudden turn, and all 60 people in the class were transported into the bloodthirsty wilderness! **
> School bully Chen Xiao held his lighter high and proclaimed himself the "Sun God Envoy" while the primitive people knelt down in worship.
> His first order was to sacrifice my nemesis, Lin Xi from the Department of Archeology, to the saber-toothed tiger: "Disaster, go to hell!"
>
> On a rainy night, I was pushed out of the tribal cave.
> Behind him is Chen Xiao's ferocious smile, and in front of him are the fangs of the giant beast.
> **But they forgot, my graduation thesis is "Technological Restoration of Prehistoric Civilization"——**
>
> **On the first day**, I sharpened my flint and spear to kill the ferocious beast, and the wolves stood guard for me;
> **On the tenth day**, I boiled brine and dried salt to build a salt valley, and the tribe women defected overnight;
> **On the 100th day**, I burned pottery and smelted copper to make a giant crossbow, and the three major tribes surrendered!
>
> When Chen Xiao raised his gun to my forehead: "There can only be one god in this world!"
> I smiled and pointed behind him——
> The primitive god of war whom he personally promoted was piercing the tip of a bronze spear into his heart: "The ancestors said it's time for you to repay your debt."
>
> **But the real horror has just begun:**
> The countdown to Halley's Comet appears in the tribal sacred bone fragments, and luminous bacteria crawl out of the World War II helmet...
> **We finally discovered that this wild world is actually——
> **The "Human Screening Experimental Field" of advanced civilization!
