"This is Keen-scented Powder. Have someone sprinkle it on Emperor Ziyan, and I will be able to track wherever he goes,"
Lin Caisang said, reaching into her small bag and taking out a large porcelain bottle and placing it in front of Prince Niu.
Looking at the large porcelain bottle in front of him, the corners of Prince Niu's mouth twitched almost imperceptibly.
He knew what Keen-scented Powder was, but such a thing still had a scent. It might be useful for others, but it probably wouldn't work on Emperor Ziyan.
"There are many capable and peculiar people around Emperor Ziyan; this Keen-scented Powder might be useless,"
"How could it be useless?"
Hearing his words, Lin Caisang chuckled dismissively.
"The Keen-scented Powder I have concocted is colorless and odorless to humans. Don't worry, no one but my Da Bai can smell it."
"Colorless and odorless?"
Prince Niu raised his eyebrows and looked at the porcelain bottle on the table.
