Xiao Hongliao knew one of the methods.
And when she was teasing Ding Sigu, she had done that.
That was the only beautiful memory.
Ding Sigu got up and stumbled toward the medicine pouch.
Special herbs that Xiao Hongliao carried with her were all in this pouch; Ghost Servants were not adept at using external things, so they casually discarded such objects.
Ding Sigu clutched the red medicine pouch tightly.
For the first time in his life, he might have conceived a thought even more insane than doing evil—he wanted revenge, to avenge Sister Hong Liao. Sister Hong Liao's death couldn't be in vain, even if he was alone, entirely alone, he wanted to make that damned Ghost Servant die!
Ding Sigu opened the red medicine pouch, revealing several small cloth bags inside.
Ding Sigu recollected the steps Xiao Hongliao took in making that special powder and started to recreate it bit by bit.
After numerous attempts, he had succeeded.
