A few minutes later, the students were gathered in the gymnasium. Everyone had to go through a mana scanner,
The mana scanner was set up at the entrance of the gymnasium, standing tall like a security checkpoint. It looked like a large, metallic archway with glowing lines running along its frame. As each student stepped through it, a soft blue light passed over their body, scanning for any signs of unusual mana or abnormalities.
If everything was normal, the light turned green, and the student could proceed. If something unusual was detected, the light would turn red, and they would be flagged for further investigation.
The dean stood at the front, explaining the situation clearly. "We've had reports of these creatures called Siphon Wraiths. They look like mosquitoes with black, sticky wings and a large bump on their backs. They drain the life force and mana of their host. If you see anything like this, report it immediately."
