The Boulder Took Away My Memory

Tribal chiefs attend international meetings with satellite phones; Paladins of the Church judge evil heretics with shotguns; The scientist controlled his mind to evenly mix the two substances in the reagent bottle; Doctors focus on rotating and enlarging the holographic projection, and use three-dimensional imaging medical equipment to perform remote surgery on patients; The workers building the fence stood on the edge of the island, looking at the cluster of houses scattered under their feet and the distant sea, sighing at the vastness of the world; ... This is a colorful world, but I just want to know why my memory is missing. (Not first person) (The protagonist is not a stone either)
