Fang Zhen leaned forward, carefully examining the content displayed on the screen.
He had run tests before. Items that couldn't be used in Casting couldn't be dragged into the synthesis slot. For example, the Blood Essence Stone couldn't be moved there.
But the Smart Pills in his hand could be.
According to the Casting formula book, the Smart Pills were either the primary component or a required material. It had to be one of the two.
Fang Zhen rubbed his chin.
He didn't have that many items in his inventory. He could figure it out through a process of elimination.
Four or five minutes later, Fang Zhen successfully figured out what could be Cast with the Smart Pills.
It was the Energy Gel.
The mango-flavored Alchemy Medicine that restored Spiritual Power and stamina.
Although he still hadn't figured out which was the primary component and which was the required material between the Energy Gel and the Smart Pills, it wasn't a major issue.
Fang Zhen felt an impulse.
