boring hes alchemist what is he doing only what chapter did he used alchemist

He's using it every chapter creating items, modifying his body,changing materials into other materials etc. All of the stuff he's doing rn are like the Holy Grails of Alchemy especially body modification and transmutation I feel like you're looking more for a crafter manhwa than an Alchemy one but tbf this manhwa doesn't do a lot of Alchemy explanation it just pulls a "random bullshit go"
