Qiao Yanyu's treatment wasn't difficult.
Previously, Qi Xibei had informed Qiao Yanyu not to take the medicine the crown prince had sent over. Qiao Yanjue did as he was told.
Therefore, the difficulty was greatly reduced.
"Did you leave that pill behind?" Qi Xibei asked.
"Yes."
Qiao Yanyu nodded and took out a small bottle.
The bottle was very small, about the size of a thumb. No one would be able to discover it even if he hid it on his body.
Even when Qiao Yanyu jumped into the water, he didn't fall out.
"Let me see." Qi Xibei reached out his hand.
"Alright."
Qiao Yanyu handed the bottle to her.
Qi Xibei had high attainments in alchemy, but this was not his specialty.
Qi Xibei opened the bottle cap, and a sweet smell rushed out.
The smell was quite sweet, not like poison at all.
However, after sniffing a few more times, one would realize that something was wrong.
