This wizard only wants to take students

Crossed to the dark and cold wizard world.
Lucian found that his system was a little different from the normal cheat code.
System points? Chip activation?
None of them, but being a role model, turning into a spring breeze:
Teach students knowledge and give back advanced knowledge.
Care for and protect students, get rich rewards.
[Your students have learned the magic potion [Kuruz's choking cough], congratulations on getting the improved formula [Kuruz's choking cough·modified]! ]
[Your students have learned witchcraft [fireball], congratulations on learning witchcraft [fireball·large]! ]
[Your students have successfully refined the witch tool [pale mask], congratulations on getting the witch tool notebook [pale mask·modified]! ]
At first, Lucian still refused.
But after experiencing what it means to teach apprentices and feed the master to death, Lucian felt that he had completely turned into the shape of a master system.
Isn't this thing much more useful than deep blue?
