Collective Time Travel: I Relied on a Slingshot to Become the Boss of the Base

[Survival + Farming + No System + No Superpowers] A mysterious and unknown powerful force threw the entire office building into the wild jungle 50,000 years ago. With 24 floors and 24 isolated islands, more than 6,000 urban white-collar workers faced the primitive jungle tens of thousands of years ago. Food became the first difficulty they had to overcome. Zhang Feng clenched the courier in his hand - it was a compound bow that had not yet been opened, but he knew the dangers of human nature. Before he had strong power, he could only hide the bow in the computer room. When the base went from hunting rabbits with a slingshot, barely surviving starvation, to later manufacturing wind turbines to light up searchlights, the saying that technology is the primary productive force has continued to gain more meaning. Zhang Feng also successfully transformed from a social beast who did not even dare to kill his enemies to a king who killed decisively; In this civilized game that spans fifty thousand years, he will use the most primitive weapons to create the cruelest rules of survival. Humanity, animality, instinct, that is the ticket to advanced civilization.
