Introduction to Omniscient Alchemist: A failed chemistry experiment caused the soul of lab assistant Gong Hao to transmigrate into another world, reincarnating as Xiu Yi Ge Lai'er, a commoner youth. Unfortunately, he was sold to the Nightmare Island - the empire's secret alchemical experimental base, becoming the lowest servant and potential sacrificial experimental material. Fortunately, he still has some time to change his fate: desperately absorbing all kinds of knowledge and skills, studying and improving the lost ancient alchemy, and becoming the strongest omniscient alchemist proficient in magic and martial arts. Step on dragons with magic and martial arts, and make even the demon gods tremble before my puppet army!
