Nailisi acted on her own and killed the sorcerer at Yaoyang City, but she remembered Saleen telling her to head home before dark, and it was not an order she wanted to disobey.
She convinced Aston to cheat Sufonso and left the magic tower, planting magic bug eggs on the 12 magic apprentices. The eggs would have hatched any time by Nailisi's will, making it easy for her to deal with the apprentices.
Nailisi left behind five demonic spirits and shapeshifted them into mages using Ultimate Shapeshifting, leaving them behind at the tower. The demonic spirits were also capable of hatching the eggs, which would have served well in cutting off the possibility of the magic apprentices betraying her.
As for Aston, Nailisi saw no need to use any tricks. If the white-robed mage actually managed to finish his task without being subjected to any kind of control, Nailisi would not have minded looking for a teacher for him.
