Lord of the Mysteries: The Dog of Fantasy and the Maid Who Tests Potions

My name is Lin Qing, and I'm a psychological counselor. I'm freaking out right now because I've transmigrated. Most people at least transmigrate as a person, but I became a big golden retriever. To turn back into a human, I have no choice but to embark on an unprecedented path to transcendence. Fortunately, there's a drop of “Chaos Source Liquid” in my mind that can absorb Beyonder Characteristics from specific pathways and put them to use. So as long as I keep my head down and survive, sooner or later I can reshape my flesh and blood and become human again! My owner, Audrey, is a beautiful and kind young lady. Not only does she generously give me shiny gold pounds, she even tests medicine for me in advance. I swear, she's the kindest young lady I've ever met! But I think I've gotten myself into trouble. I was dragged against my will into Mr. Fool's realm, and accidentally knocked a few of his cocoons down... It's fine, it doesn't matter. I'm just a dog who wants to be a dog. What Mr. Chariot does has nothing to do with me, Susie. Come to think of it, what does the Avengers Alliance formed by Emperor Roselle have to do with a big golden retriever like me? But... I might need to set a small goal first, like figuring out how to tell my medicine-testing maid, Audrey, to stop scheduling sterilization surgery for me! (P.S. The protagonist's gender follows the original work: using “he” instead of “she” is a small hint. Also, there is no female lead.)
