Having made a handsome profit, Duan Qing was in exceptionally high spirits and asked Qingyao to properly escort Lord Mi out.
Mi Lan attached great importance to the matter of Evil Cultivators; either they made no move, or once they did, they had to wipe them out entirely without leaving a trace of what had transpired for the outside world to know. Retaliatory actions like the one Li Yutao had pulled could not be allowed to happen again. Moreover, no one could predict if accidents might occur, or if a powerful Evil Saint might descend. Even Mi Lan himself could not be certain whether a lethal array combined with a Holy Talisman would be enough to slay an Evil Saint. Therefore, Mi Lan preferred to pay a hefty price to have Duan Qing stay and hold the fort.
As for whether Duan Qing would slack off and refuse to put in genuine effort? Mi Lan had plenty of ways to force him to act. Since he had already come, escaping unscathed was not going to be so easy.
