After drinking the potion, Thirteen immediately felt light-headed, and his thoughts seemed to scatter, making him unable to think properly.
However, instead of being alarmed, the boy felt amused because Rafiki's truth serum was better than he thought.
Although he could make something better, he didn't have the necessary ingredients to concoct one.
For the time being, he allowed the truth serum to take full effect on him in order to prevent the General and Rafiki from becoming suspicious of him.
As a System, his mind was his strongest weapon.
A mere truth serum was nothing to him!
Seeing the blank look on the boy's face, Rafiki glanced at the General and nodded his head.
"What is your name?" General Stark asked.
"Zion," Thirteen replied. "Zion Leventis."
"How old are you?"
"Seven and a half years old."
The General continued to ask the boy several questions, testing if the truth potion was working properly.
