Pushing open the heavy oak door, there were already six or seven apprentices waiting inside, with Master Thompson organizing the test materials at a long table.
"Ah, Ron, just in time."
Thompson saw him and showed a satisfied smile on his face:
"Today's test is energy storage in alchemy, as you know, it is the most basic but also the most important skill in elementary alchemy."
Ron smiled slightly: "Yes, Master Thompson, I am ready."
"Good, your place is over there, the materials are ready."
Thompson nodded, pointing to a workbench:
"The requirement for this test is: complete the sealing of a standard energy core within an hour, with stability and purity as the main scoring criteria."
Ron came to the designated location and saw various alchemy materials on the workbench:
A piece of ordinary stone as the base, several basic mineral powders as conduits, and a small bottle of refined magic liquid to provide initial energy.
