Only after binding himself to the “Protagonist Development” System did You Ningyu learn that he was the vicious male supporting character in the book, with very little talent.

The System told him that every time he bullied the protagonist, his cultivation would improve by one step.

So You Ningyu bullied the protagonist whenever he got the chance. He treated him like a dog, putting a leash on him, tripping him up, poisoning him with Gu, and beating and berating him at will…

His methods were so ruthless that even the System was left speechless. But the protagonist never showed the slightest desire to fight back. He even acted like a real puppy, keeping watch beside You Ningyu's bed and looking at him with cautious, ingratiating eyes. “Master…”

Later, the System pointed to the grown-up protagonist and told him, “You bullied the wrong person. That's the villain.”

“What?! Am I even going to survive this?”

You Ningyu took the lesson to heart. That very night, he packed his things and returned to the mortal world, planning to hide at the Chancellor's residence for a while. But someone chased after him that same day.

Wen Shigui's expression was dark, and his eyes no longer held the innocent confusion of his youth. He stared straight at You Ningyu, his voice icy. “Brother, are you leaving without a word again?”

“People who don't behave… have to be locked up.”
