[Pharmacy] was a 9 Star Skill.
It was precisely because God's Path had yet to truly activate the function of "Precious Medicine Fusion."
God's Path had a total of four major fusion systems.
They were the Treasure Fusion System, the Skill Fusion System, the Weapon Fusion System, and finally, the Treasure Medicine Fusion System.
When God's Path descended, the treasure fusion system was first opened.
In the 10th year of God's Path, the Skill fusion system was opened.
In the 20th year of God's Path, the weapon fusion system was released.
Only the last precious medicine fusion was not available yet. Until now, every player was only given a chance to experience it once.
Ling Yi had already used up this opportunity when he created the [Natural Sacred Medicine].
If he didn't have [Alchemy] now, he wouldn't be able to fuse any more precious medicine.
It was also because of this.
