Very soon, the two Merfolk arrived in front of Fang Ka and spoke respectfully, "Lord Fang Ka, is there anything you wish to instruct us?"
Fang Ka glanced at the two Merfolk and then spoke, "Take a batch of Alchemy Potions to Xia Lin, and once Noel returns, have her immediately take them to the Underground City and give them to Tina."
After speaking, Fang Ka immediately walked towards the Ancient Castle.
The Alchemy Potion he was handing to the two Merfolk was the Biphasic Potion.
The Biphasic Potion can detect whether a person possesses the Demon Source of a Mage, or the Vital Acupoint of a Knight.
Simply put, it determines whether a person has the talent of a Mage or a Knight.
This thing is very easy to brew, last time when testing Gana's corpse, Fang Ka made quite a lot.
Very soon, Fang Ka came out of the Ancient Castle with two large wooden crates, filled to the brim with Biphasic Potions.
