Pre-Chapter Statement: This article is a fanfic about Tianmeng's guest appearance in Harry Potter. I have just started writing it, so please give me time. Besides, I can't get up at night to rush the manuscript. There is not much time, but I will never give up (please rest assured, Tianmeng fans and Harry Potter fans). PS: I have no confidence in my typing speed, but I will try my best. (Laughs) Colleagues who have read the novel version of Harry Potter can once again see the appearance of the dead Professor Albus Dumbledore and Gabriel who is studying to become a wizard in Hogwarts College in this article! (Gaga is reincarnated! She is a girl)
