Master Qiao still had an ace up his sleeve!
His last game-changer!
That was the Purple Robe Ghost, the Qing Dynasty ghost girl Fangfang!
Although Huang Xiaolong had encountered this secret weapon before, it did not deter Master Qiao's master plan.
Summoning ghosts, especially high-rank ones, is a challenging task for a Taoist. Besides being difficult to summon, the ghosts could potentially possess the summoner.
Fangfang, a ghost nurtured by Master Qiao for decades, started as a mere Green Robe Ghost killed by Master Qiao in his pursuit of wealth. It was this malevolent act that resulted in the birth of the Purple Robe Ghost.
Fangfang can be seen as Master Qiao's child, personally brought up by him. Through various means, he managed to control Fangfang flawlessly.
If Master Qiao were to summon a ghost at the scene, with his skills, he could only summon the wandering spirits nearby. If lucky, he could summon lower-tier Red Robe or Orange Robe Ghosts.
