[Two male protagonists/Reborn villain/Dog training/Qiangqiang/Two villains/Fall in love and kill each other/HE/Death escape/Three wrong views] [The truly vicious dog-training brother who holds the system is attacked by the reborn villain crybaby puppy brother] - After being bound to the "Protagonist Training" system, You Ningyu realized that he was a vicious male supporting character with extremely low talent in the book. The system told him that as long as he bullied the protagonist, his cultivation would improve further. So You Ningyu caught the protagonist and bullied him when he had nothing to do. He treated the protagonist as a dog, tied ropes, tripped him, placed poison on him, beat and scolded him arbitrarily... The ruthlessness of his methods even shocked the system, but the protagonist didn't even have the slightest thought of resisting. He even squatted beside his bed like a real puppy, looking at him cautiously and flatteringly: "Master..." - Later, the system pointed at the grown-up protagonist and told him: "You bullied the wrong person. This is the villain." "What?! Then am I still alive?" You Ningyu learned from the pain and packed his luggage and returned to the human world that night. He planned to go back to the Prime Minister's Mansion to hide for a while, but he didn't expect to be chased down that day. Wen Shigui's face was gloomy, and his eyes were no longer as ignorant and innocent as before. He stared at him directly and said in a cold tone: "Brother, are you leaving without saying goodbye again?" "Those who disobey will be locked up."
