[Harry Potter] The Snake Ancestor at Hogwarts

[The main story and the reading-reaction bonus chapters for Part Two are complete. Part Three, The Last Slytherin, is in the works. See the author's profile for details.] [The new story, Formation Across the Primordial World, is currently updating.] Salazar Slytherin came from the mud. Pure-blooded, devious, and cunning. He craved power and liked ambitious young men. He was the first to propose the Pure-blood doctrine, believing that magical education should be limited to children from purely magical families. This belief caused a rift between him and the other three Founders of Hogwarts, and in the end he left the school alone. According to the records of the wizarding world, he was the most terrifying Dark wizard of the Middle Ages: powerful, shrewd, sinister, and frightening... Yet one day, everyone at Hogwarts suddenly discovered that Salazar Slytherin, the supposedly decrepit old man who looked like a monkey and had a sparse, long beard that nearly dragged along the hem of his robe, was apparently, possibly, perhaps, maybe... a beautiful little girl?! Casablanca Slytherin gazed innocently at everyone with her big, misty eyes and tilted her head. Behind those eyes, black as the night, the sky seemed to clear after the rain, gazing at her tenderly. Note: 1. This is a pseudo-genderbend story. Because of a misunderstanding, everyone thinks the Serpent Founder is a cute girl, and they all say their worldview has been shattered~ 2. Truly two souls in one body. Although the author loves little girls, my Salazar is still a male idol. Also, the author's headcanon about the Serpent Founder is immense!!!! 3. The background incorporates Hebrew mythology, but Heaven and Hell represent only natural alignments and factions, not good and evil. Angels and demons are just making cameo appearances. The main goal is to give S.S. and G.G. special advantages and a reason to appear a thousand years later. 4. The original work belongs to the great JK. The author will do their best to study it carefully. However, given the author's terrible writing and reading comprehension, OOC is inevitable. Canon sticklers, please go easy on me. 5. The main CP is tentatively Serpent Founder X Lion Founder. The secondary CPs depend on how the story develops. There may be Draco/Hermione, the Serpent Founder's sister X Harry, and other pairings that break up canon couples. Of course, GGAD will absolutely not be broken up! ■■■ ADVERTISEMENT ■■■ Ongoing story, Formation Across the Primordial World: Demon Emperor Dijun CP Sect Master Tongtian. It combines the Primordial World genre, Taoist mythology, Investiture of the Gods, Journey to the West, Lotus Lantern, and more. I'm trying to update daily.
