When energy shields and steel swords coexist, when genetic modification and campfire heating coexist - welcome to the "Erosion of the Abyss". Here, civilization is rebuilt in dislocation, and the truth is buried under the faults. Lin Qi, a low-level technician who maintains "ancient technology", was exiled to the wasteland for cracking a code. He soon discovered that the high technologies being enshrined were not ancient, and the so-called doomsday was actually a civilization screening experiment that lasted for hundreds of years. Is knowledge a privilege or a right? Should civilization be guided or evolve independently? Holding the truth that will overturn the world, he will make a choice - this time, the future will be written by the earth itself.
