Why Hasn't the Protagonist Turned Evil Yet?

A nurturing, beautiful, tragic bottom who loses his teaching license × a sweet yet devious, devoted, dark and possessive top

Nian Xianyue had hit the jackpot: he was transmigrated into a xianxia novel as a cannon-fodder shizun.

His task was simple: torment his protagonist disciple, Luo Shuangtian, as much as possible. Once Luo turned dark, stabbed him with a sword, and embarked on his path to becoming the ultimate hero, Nian could go home and collect his bonus.

So he played the wicked shizun with complete professionalism, putting his disciple down, withholding resources, and ignoring him emotionally. His professional standards were impeccable.

Even disciples from other peaks privately complained that the master of Lingjue Peak was far too harsh, mercurial and unpredictable, and utterly detestable.

But Luo Shuangtian's reaction took everyone by surprise:

“Shizun scolds me to spur me to improve!”

“Shizun withholds resources to teach me self-reliance!”

“Shizun ignores me... I must not be trying hard enough!”

Nian Xianyue: ...

Young man, do you need counseling and legal aid?

He tried to spell it out: “I'm a bad person.”

“No, Shizun is the best person in the world!”

“I torment you every day.”

“That's just Shizun's unique way of teaching me and showing his love!”

“If you keep this up, I'll really hit you.”

The young man's eyes lit up. “Shizun is going to train me personally? I'll go get my sword!”

“...”

Was this mission even possible anymore?

His disciple's mindset kept veering further off course, and there was no way to get things back to how they were.

Then, on a snowy day, the plot forced Nian to unleash all his malice and personally pierce his disciple's spiritual core. As the System announced Luo's corruption value, it cheered: [Congratulations! Affection has exceeded its limit!]

Only then did Nian realize that beneath the mild-mannered, taciturn protagonist's exterior lurked a psychologically twisted mad beast.

Later, Nian Xianyue died protecting the sect. His mission was complete, but his soul was sealed away. The last thing he heard was the young man's bloodcurdling whisper.

“Someone will pay for Shizun's blood...”

When he opened his eyes again, it was ten years later, and he was in an unfamiliar body.

The System wailed: [Host, the protagonist is about to turn the entire cultivation world upside down. Please, save my poor performance record...]

A new mission appeared, but its goal was completely different. Wearing a face even he found unfamiliar, Nian Xianyue tried to infiltrate the palace called Frostmoon.

Until someone nearby said with a puzzled look:

“Your Lordship has been right behind you this whole time.”

Nian Xianyue shuddered. Then he heard a low, ghostly voice.

“Stay by my side forever... Shizun.”

*One-on-one romance, both are each other's only partner, happy ending.
