Bai Cheng gets sent to an online game world by a bolt of lightning falling from the sky, and his starting class turns out to be a C-rank Contract Summoner.

Good thing his class isn't enough on its own, because the system's here to pick up the slack.

"Contract Cultivation System bind successful!"

Just as Bai Cheng thought he could sweep through the game with powerful contract spirits, he discovers something's a little off about this system.

What do you mean race doesn't matter, talent doesn't matter, but the contract spirit's age is what really matters?

"This system will grant cultivation bonuses or attribute bonuses based on the age gap between the host and the contract spirit!"

"Note: per system guidelines, this system does not condone the employment of child labor. Violators will be punished."

And among the 3 starting contract spirits, the only one that seems to fit the requirement is a 3-year-old, young, female Little Octopus.

Bai Cheng: System, let me explain!

System: Explain what? Just zap him!

Waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaah......

......

"That guy's got a little white-haired loli with no expression on her face sitting on his shoulder, and she can summon tentacles."

"Floating in front of him is a little red dragon loli, covered in flames, with wings and scales."

"Trailing behind him is a shy little pink-and-white-haired loli who can transform, and when it comes to actually cutting people down, she's more ruthless than anyone."

"Oh right! He also randomly sparks with electricity from time to time!"

That's how people who know Bai Cheng describe him.

Bai Cheng: I'm just raising some lolis, so how did I somehow end up invincible?

System: Zap zap zap zap zap zap, I'll zap you to death, you pervert!

The system's rewards run on age gap, but that doesn't mean you're only allowed to contract with the young ones!
