[Invincible protagonist][HP + MCN + Harry Potter: Magic Awakened + other magical world][Ruthless system novel][Humorous]

Young An Ang travels to the magical world and, after many hardships, becomes the Sorcerer Supreme. Just as he is about to take control of Kamar-Taj, he suddenly receives an owl from Hogwarts and awakens a heaven-defying system. As long as he completes the heaven-defying tasks, he will receive unexpected artifact rewards.

An Ang smiled. It was time to give the magical world a little shock from the Sorcerer Supreme!

Why did the Savior change from a man to a woman? Why did Professor Snape cry during class?

Why does Professor Quirrell keep getting elbowed in the back of the head by giants?

Why is Professor McGonagall obsessed with mysterious plants? What kind of bizarre quest is "Educating Hermione"?

Why did all the Death Eaters suddenly start clamoring to quit overnight?

How will this terrible darkness, which threatens multiple magical worlds, end?

It all started on the day that the Venerable Master An Ang entered the academy.
