Inventions in Primitive Society (55 Episodes, Free)

What he brings is not a miracle but a set of methods anyone can repeat. While others still smash with stone, he has smelted bronze; while others eat what the sky gives, he has dug canals and built granaries. When the neighboring clan comes with torches to raid, he hands every hunter a first pair of bronze armor and stands on the wall: 「This time it isn't a raid. It's a delivery.」 Lin Yue opens his eyes in animal skins, mud under his feet, and a sky with not one tile over it. He has landed in a primitive tribe and is worshipped as a shaman fallen from the sky. The tribe is on the edge of starvation: no food storage, no pottery, an infected wound means death, and winter is survived by abandoning the old. In three years he turns all of it around: the first kiln of pottery, the first furnace, the first bronze blades, salt drying, net weaving, bone setting, counting. The tribe grows fat, and the neighbors' eyes turn red.
