Origin of Civilization

An international flight carrying 300 people fell into a rift in time and space. When structural engineer Lu Chen woke up from the ruins, there were two moons above his head. This is not Earth. The giant beast howled in the dark, and the primitive tribe with chalky face patterns raised their stone axes. Twenty survivors, the wreckage of a plane, and a three-dollar pen. Lu Chen has no system and no storage space. He only has the structural mechanics in his mind, twenty years of blood and sweat on the construction site, and a very costly ability - knowledge engraving. When the opponents inside shouted for rescue, he had already started to build the first wall; when the projectile device of the Stone Tooth Tribe penetrated the camp, he discovered something even more terrifying under the stone wall - an ancient ruin that had been operating for thousands of years and was slowly waking up.
