Since Rezen is not aware of how extensive the Chief's knowledge was, he absolutely cannot answer truthfully. After all, even he still doesn't know just how 'special' his mana was
However, there is one thing that Rezen knows. A special ability at the hands of a weakling is nothing but trouble in most cases
Rezen cannot deny what he had already done and there is only one thing he could do
"I-I... I don't know. I... I just felt that if I let the seed absorb my mana... s-something will happen..." Rezen replied as if he was really shocked at his own action and its result
He stared at his palm then glanced at the potato plant before staring at his palm again
"W-why... h-how did I do that..." he mumbled lowly but it was still loud enough for the Chief to hear
"Rezen..." the Chief's tone became harsher than before, she wants to pry on Rezen's secret but before she could do so, Rezen already upped his acting game
"A-argh....!"
