According to the normal conversion rate of mana for a tier seven treasure of 200, it's equivalent to consuming 20,000 mana.
This Mouse Demon has 160,000 mana, having used nearly half during the previous battle, leaving seventy to eighty thousand mana, which cannot withstand such terrible depletion.
Within one minute, nearly 20,000 was depleted, and with Ao Run's relentless attack, the Mouse Demon's mana was exhausted in just four minutes.
Seeing its mana running out, the fierce glow disappeared from the Mouse Demon's eyes, replaced by clarity, and it spoke human words:
"Human, spare my life, I am willing to recognize you as my master and serve you."
Before Su Yu could respond, Ao Run reacted with strong opposition:
"He's too smelly, if you agree, never touch me again."
Su Yu.....
He showed his stance with actions, wielding his swords even more fiercely.
