Ou Yangming's face changed. He immediately closed the bottle's cap but when he took a glance, he noticed that a bit of the immortal liquid had indeed been lost.
An ordinary person could not have distinguished the difference in the amount, but every change was visible to Ou Yangming when he looked with his mental conception. He had opened the bottle that stored the first drop of immortal liquid, and there was no change to the liquid when the bottle was sealed. Once he opened it again and allowed the fragrance inside to be released, a tenth of the drop of liquid was lost.
Although the remaining liquid was still considered a drop, to people like Ou Yangming, it had depreciated very much.
"Lil' Red, what exactly is the function of this thing?" Ou Yangming asked in a deep voice.
The little red bird flapped its wings and answered, "It's a rare immortal liquid. Apart from its basic function of prolonging one's life, it's also... Multifunctional."
