This wizard only wishes to be a teacher

He had crossed into the dark, ruthless Wizard World. Lucien found his system somewhat different from the usual golden finger. System upgrade points? Chip activation? None of these, but rather becoming a role model, transforming into a nurturing breeze: Teaching students knowledge, receiving advanced knowledge in return. Caring for and maintaining students, earning generous rewards. [Your student has mastered the Magic Potion "Kuru's Cough," congratulations on acquiring the improved formula "Kuru's Cough - Enhanced"!] [Your student has mastered witchcraft "Fireball," congratulations on learning witchcraft "Greater Fireball"!] [Your student has successfully crafted the wizard's tool "Pale Mask," congratulations on acquiring the wizard tool’s manual "Revised Pale Mask"!] Initially, Lucien was resistant. But after experiencing what it was like to teach disciples and outdo them, Lucien felt he had completely transformed into the form of the master system. This thing, isn't it much more useful than anything deep blue?
