บท 68: How… just how?

The smirk on Harry's face only widened as he muttered two words: "Mana steal."

[Mana steal activated]

[+5000EXP]

His eyes widened slightly, the amount of EXP he gained when he used [Mana steal] on Han couldn't compare to this.

Ever since that day when he used the skill on Han, this was the second time he would be activating the skill. 

It wasn't that he was pitying the students and didn't want to steal their mana, it was just that it would be too risky. 

The mana sense of the academy instructors was very strong and acute, if Harry tried to steal mana from an Elementalist in the academy, the chances that he would be discovered by an Instructor were quite high. 

However, here he was safe from any risks. The librarian in the spell library was only a stage two elementalist so her mana sense wasn't strong enough to detect him stealing mana, the mana sense of the few students in the library was also weak so his skill couldn't be detected.
