I Didn't Choose the Gangsta System, the Gangsta System Chose Me Chapter 13 - After Class

"Class 6?" the handso zombie pointed below.

Mister Jack shook his head.

"No, this is Class 10." he was turned off since this handso man was a zombie. However, he still answered politely.

"6... where?"

Mister Jack sighed and went outside to point at a direct down the hallway.

"This is 10, besides this is 9, then 8, 7, and 6. That's where your class is."

The zombie looked at where Mister Jack pointed. However, he scratched his head and made a confused expression.

Mister Jack saw this and explained how that class is not 6. However, the zombie was still confused, showing its rock-bottom intelligence.

Seeing how Mister Jack gave his best to teach the zombie the number system, addition, and subtraction, the fish spoke to Joren.

Crack* Joren clenched his fist in annoyance and broke the pen. Now its ink covered his hand and his notebook.

A terrifying aura surged from Joren.
