[Alchemy + Genius + No System + Time Travel + Invincibility] Xia Xuan traveled through time and became a dying child on the Shenxi Plain. At the age of twelve, he was entrusted by the legendary alchemist Shi Jian to Li Wei, the president of the Alchemy Branch of Furnace City.
Xia Xuan used the fragments he picked up to save the kitten, but was called a heretic by the temple inspectors. The machine he built based on modern knowledge was criticized by the Alchemy Federation as plagiarism. His invention of the internal combustion engine was called useless by high-level alchemists...
Xia Xuan went into seclusion for five years. When everyone thought he was oblivious to everyone, Xia Xuan secretly invented a bracelet that could fight against order; when the temple wanted to control him again, he found that the magic did not work; when the Alchemist Association wanted to hire him again, he couldn't afford it.
In a magical world, one does not cultivate immortality or learn magic, but masters the rules and advances in technology.
