After Becoming a Teacher, I Get a Genius Student System?

I'm in Gaowu, I'm already thirty and have accomplished nothing, but fortunately...

[At the age of fifteen, you have already reached the bone training level.]

【The genius student system has been activated! 】

[Teach the future Demon Lord a lesson, and make him understand that you are the king here! ]

[Reward: Perfection-level Fulong Spear Technique]

As a teacher, Li Jun scolded the future Demon Lord without fear.

Next second.

Mission accomplished!
