Hogwarts: I am the White Demon King

[Harry Potter fan fiction + professor writing + education reform + layout + make up for regrets after the main story begins]

[Slowly warming up! There are new education reforms every year]

Sebastian Swann, an outstanding graduate of Slytherin, heir of an ancient alchemy family, and the richest man in the wizarding world. 12 years after graduation, he returned to Hogwarts as a professor...

Snape: "Sebastian, what made our richest man choose to be a little professor at Hogwarts?"

Sebastian: "To make Slytherin great again!"

Snape: "Tell the truth..."

Sebastian: "To make Hogwarts great again! ... Put away the truth serum, Severus, you are such a bore!"

Snape: "Tell the truth!!!"

Sebastian: "It's all true, except... I still want to make wizards great again!!!"

......

ps：

1. The protagonist graduated from Slytherin, is Snape's friend, and is not very friendly to the deer dog

2. The original female protagonist (a tool person) has no sweet love. The male protagonist is focused on his career and has no children for the time being.

3. Focus on Slytherin's shrewdness and ambition, not bloodline

4. Contains two settings

5. The timeline begins in the second year of the Weasley twins, one year before Harry and the other two enter school.

6. Lightning avoidance: This is the White Lord!!! Not the Dark Lord!
