Who Says You Can't Become an Immortal at Hogwarts?

"Who says you can't become an immortal at Hogwarts?" "Have you ever practiced immortality? If you haven't, don't jump to conclusions!" Zhang Xi, who had never practiced immortality, cherished the Taoism taught by his family, learned magic at Hogwarts, sang songs, and somehow became an immortal! You want to ask how he became an immortal? "Basilisk, good friend! Lend me your snake gall to make elixirs, and your flesh and blood to make your magic stone." "Dementors are also good ghosts! Not only do they not blame me for pouring black dog blood on them, they also help me explore Yin and Yang." "Ministry of Magic, good friends! Let me visit the Department of Mysteries wherever you like. Minister Fudge and Professor Umbridge are both good people!" "Voldemort, what a great man! He lent me his luck and his soul for research." Zhang Xi finally concluded: "What I have achieved today is all due to everyone's selfless dedication!"
