With Clay's Multithreading Parallel Thought Processing combined with the Self-Mastery skill, he could remember all the knowledge and information he has acquired through all means in his lifetime. Using the knowledge and some speculation on science, technology, theology, literature, fantasy, sci-fi, and the occult that he'd accumulated over decades previously on Earth, finally being completely available to his recollection, Clay began researching for ways and means to level up and breakthrough to the Ascendance Stage without painting a red dot over himself. Utilizing science and magic theories from the occult, anime, manga, novels, and other sources, he combed and put together, and finally acquired a skill called [Forbidden Knowledge] which enabled him to experiment via simulations in his mindscape before bringing the fully-researched and functional spells out to reality.
