Ash Erosion Chronicles

Humans imprisoned dwarf masters to steal rune forging skills. Elves regarded half-elf hybrids as a shame of blood and expelled them into the sewers. Orc shamans cried to their ancestors in their dreams in the frozen soil of the north about the homeland they were expelled from. But these are nothing compared to the price the world asks of a mortal when he tries to touch power. In this continent, the paths to becoming a professional are all kinds of strange—bloodline awakening, gods' gifts, and epiphanies between life and death. However, all safe and efficient growth methods are sealed behind expensive "enlightenment rituals" and "skill tree scrolls" by temples, guilds and nobles. People at the bottom want to become stronger? Either risk your life on an unknown mutation, or sign a lifelong contract of betrayal. Linn traveled here and found that he was an exception. A piece of light blue crystal named "Slice" is suspended at the edge of the field of vision, able to analyze everything into cold, quantifiable data. People in the world have been practicing hard for half their lives and don't know how much they have achieved, he can see it at a glance; others have lost everything just for a roll of castrated basic skills, but he can deduce the complete optimal path. In this world where knowledge is power and monopoly is dominance, he has the only "eye of rules". From the first hold of a weapon in the sewers of Gray Mist City, to the repair of the first rule line that was severed by the temple, to the completion of the compilation of the professional illustrated book spanning twelve eras - when the thrones of the gods shook the heavens, he chose to dismantle this supreme authority and distribute it to all those who were willing to record it themselves.
