[One Female Lead] + [No System] + [Cultivation]
When Shangguan Chenjin wakes up, he discovers that he has transmigrated into the world of Harry Potter,
where he has become an "orphan."
After Dumbledore sends him to live with the Delacour family, he discovers that his mind contains cultivation techniques.
But he hasn't practiced for long before Voldemort comes after him, trying to kill him...
Shangguan Chenjin: "Heh heh heh. With cultivation techniques, doesn't that mean I can save Dumbledore and Snape, and all those regrets can be avoided?!"
Snape: "Shangguan Chenjin, what are you doing? Fifty points from Gryffindor!"
Shangguan Chenjin: "What if I suddenly don't want to save him anymore..."
Snape: "Forget it, I'll give the points back."
Shangguan Chenjin: "I'll save him, I'll save him! I have to save him!"
(The protagonist values friendship and family because of certain circumstances. He's a good person, but he isn't a pushover when it comes to his enemies.)
(The author may set up a lot of plot threads early on, but they'll be resolved later.)
