Chapter 415 Yang Feng said: "I count dozens of numbers.

It seemed that Yang Feng had finally started to get serious. Before, even when he was angry, he had never used any spell against me. But now, as that unmasked hatred appeared, he began to recite a spell.

Truth be told, I had seen some of the spells from the Ghost Nurturing Spell before, when I faced that security guard. What left a deep impression on me was the guard creating a room with four pitch-black walls and no doors or windows. Now that I think about it, that pitch-black room must have been made using what Yang Feng referred to as the Crow Spirit Mist.

Thinking of this, I felt slightly relieved. After all, I already knew how to break that thing; I had managed to solve the room by sheer luck in the past.

Sure enough, the black mist grew denser and expanded rapidly, covering a large area atop the school building in just a moment. Including my body, everything was enveloped within it.
