HP: Don't Mess with That Eastern Professor in Black Robe

Chen Ke, a senior Internet writer, accidentally fell across dimensions due to an outrageous web game advertisement and landed on the lawn of Hogwarts in 1992. He also accidentally injured Sprout, the Herbology Professor. This sudden accident caused him to be targeted by Albus Dumbledore, the greatest wizard in the wizarding world. With half a push, he was forced to take over the cursed Defense Against the Dark Arts professor and become the new dean of Hufflepuff College. No one knew that this seemingly ordinary yellow-skinned oriental young man was actually a full-level magic god with terrifying power that could overwhelm half of the wizarding world. He could easily break Voldemort's vicious curse in the Defense Against the Dark Arts position, and he could even fight against all black magic on his own. He can perform top-notch magic without a wand, and he can read through Hogwarts' thousand-year-old books with just a flick of his fingertips. He can not only purify the darkness with the purest holy light, but also use Chinese fireworks to warm the teachers and students of Hogwarts. He has also quietly discovered the unknown secrets of this magical world. When a max-level Eastern mage breaks into the magical world of Harry Potter, Dumbledore's deep layout, Voldemort's comeback, and the fate of the magical world will eventually be completely rewritten because of him!
