The Strongest Tribe

Traveling through the primitive and wild world, Xia Tuo, who accidentally slapped the system to death, suddenly realized that he had done something s*upid. Dare to ask how to filter and purify salt? What and what alloy is bronze? How to make a bow and arrow? God, how could it be so difficult to be the leader of a clan… Looking at the pile of rocks and animal bones in front of him, Xia Tuo missed the system that was shot to death.
