I, Xiao Jingyun, have been working on the code for forty years, and finally died suddenly one second before ascending to the immortal world, and was reincarnated into this world of immortality. Relying on the perseverance that made me a great person in my previous life, I practiced hard for thousands of years and successfully ascended again! But what awaits me is not supreme glory, but being relegated to the lowest level of servant in the spiritual mine because of my "mediocre abilities and lack of background"! Immortal officials are superior and regard me as an ant; my colleagues bully me and regard me as a waste. They don't know that in my eyes, the entire fairy world, and even the supreme heaven, are lines of code full of bugs! Is the technique defective? I directly optimize the underlying algorithm and achieve god-level skills in one second! Is the magic weapon defective? I changed the material code with my backhand, and scrap metal turned into an innate treasure! Are the laws of heaven unfair? Haha, today I will let you see what dimensionality reduction strikes from programmers mean! I will use code as a sword and logic as an edge to rewrite the order of the world and let all the gods and Buddhas in the sky... Operate under my rules!
