Siheyuan: I Have a Devil Fruit Tree

[Courtyard house! No cultivation! The System doesn't pop up constantly! The main plot moves forward through the story!] [This book has absolutely nothing to do with One Piece. Don't pick it up by mistake!] A professional soldier arrives at a courtyard house and discovers that his comrade's little girl is being bullied... He doesn't waste words and gets straight to work. From then on, the beasts become fertilizer. What kind of fertilizer? Devil Fruit fertilizer, of course! I'll sacrifice you all... and let my Devil Fruit tree branch out and flourish. The protagonist's personality: When he's pleased with himself, he never lets anyone off the hook, and even when he's in the wrong, he still insists on arguing his case.
